Field of invention
[0001] The present invention relates to flood protection device configured to prevent water
ingress through a pipe member such as a drain or a toilet.
Prior art
[0002] Water ingress through pipe systems is a major problem. Accordingly, several water
damage protection systems have been developed in order to protect against costly water
damage. Water leaks are not always easy to notice and furthermore, by the time people
realize that their pipe is leaking, a major damage may already be done.
[0003] A typical prior art flood protection device is configured to be installed in an invasive
way, e.g. installing a sewer valve into a pipe system.
[0004] US 4494345 A discloses a sewer valve that is configured to prevent back flow of sewage into a
structure during abnormally high water conditions. The sewer back flow valve comprises
sensing means located at the top of the sewer line and an inflatable annular bladder
responsive to a sensing means to permit passage of sewage through the annular bladder
under normal water level conditions and operable to prevent back flow of sewage through
the annular bladder under high water level conditions. The sewer valve is however,
not suitable for being used in pipe systems as such. The sewer valve has to be installed
in an invasive manner which means that bores and/or cuttings have to be provided in
the pipe systems. Accordingly, installation of such system is irreversible, expensive
and requires skilled personal.
[0005] GB 2480885 A discloses a flood protection device for preventing water ingress through a sewer
pipe connecting a building to a sewer main. The flood protection device comprises
a valve engageable with a sewer pipe which, when closed, effects blockage of said
sewer pipe. The flood protection device moreover comprises a valve actuation mechanism
responsive to water contact. The valve actuation mechanism is configured to close
the valve upon contact with water. The valve actuation mechanism includes an inflatable
bladder configured to, upon inflation, effect closure of the valve. The flood protection
device also comprises means for inflating gas into the inflatable bladder.
[0006] Unfortunately, this flood protection device has to be installed in an invasive manner
which means that bores and/or cuttings have to be provided in the pipe systems. Thus,
installation of such flood protection device irreversible, expensive and requires
skilled personal.
[0007] US 20110005615 A1 discloses a fluid backup preventing system capable of blocking a pipeline. The fluid
backup preventing system is intended for being arranged in a clean out duct provided
at the pipe-line intended to be blocked. Moreover, the fluid blocking system is pneumatically
coupled to an external pneumatic circuitry arranged outside the pipeline.
[0008] US 4417598 A discloses a pneumatic valve system intended to seal of the flow of a liquid. The
pneumatic valve system is connected to an external pressure source (air compressor).
[0009] GB2480005A shows a gas cartridge with Carbon Dioxide or Nitrogen, which is used to inflate an
inflatable bladder for the prevention of ingress of rising floodwater.
[0010] Thus, there is a need for a flood protection device which reduces or even eliminates
the above mentioned disadvantages of the prior art. It is an object of the present
invention to provide a flood protection device that is configured to prevent water
ingress through a pipe member and that does not require an external pressure source.
[0011] It is a further object of the present invention to provide a flood protection device
that can be arranged in pipe systems in a non-invasive way and that is capable of
preventing water ingress through a pipe member.
[0012] It is also an object of the present invention to provide a flood protection device
that requires no batteries or electricity.
[0013] It is also an object of the present invention to provide a flood protection device
that can easily be arranged in and be removed from a pipe system.
Summary of the invention
[0014] The object of the present invention can be achieved by a flood protection device
as defined in claim 1. Preferred embodiments are defined in the dependent sub claims
and explained in the following description and illustrated in the accompanying drawings.
[0015] The flood protection device according to the invention is a flood protection device
configured to prevent water ingress through a pipe member, which flood protection
device comprises:
- a blocking member for use in the pipe member of the pipe system, wherein the blocking
member is an inflatable member,
- an actuation device,
- an actuation device configured to inflate the inflatable member whereby the inflatable
member is configured to block the pipe member,
- an actuation mechanism operable upon contact with water or manually, wherein the actuation
mechanism is configured to activate the actuation device and hereby make the blocking
member block the pipe member of the pipe system wherein the flood protection device
is configured to be arranged in the pipe member and to be removed from the pipe member
without damaging the pipe member and with no structural change of the pipe system.
No cutting, drilling or other invasive procedure is required in order to arrange the
flood protection device in the pipe member.
[0016] According to the invention, the actuation device is a gas cartridge comprising compressed
gas such as Carbon Dioxide or Nitrogen whereby the gas cartridge is arranged within
a surrounding inflatable balloon member.
[0017] Hereby, it is achieved that the gas cartridge can provide a fast and efficient filling
of the inflatable member (e.g. a balloon member) and a compact flood protection device
can be achieved. Furthermore, the gas cartridge can is protected against impact while
being arranged in the pipe member during the positioning process.
[0018] Further, the flood protection device can be arranged in a pipe member without being
connected to an external pressure source. Further, the pipe member does not need to
be modified and that no clean out duct is needed to install the flood protection device.
Moreover, the flood protection device can be arranged in pipe member in a non-invasive
way and still prevent water ingress through a pipe member. The flood protection device
can easily be arranged in and be removed from a pipe system.
[0019] The term "without damaging" means that no structural change of the pipe system is
required. This means that no cutting, drilling or other invasive procedure is required
in order to arrange the flood protection device in the pipe member.
[0020] Hereby a quick, efficient and reliable blocking of a pipe member can be achieved.
[0021] Also, a very efficient and reliable way of blocking a pipe member can be provided.
[0022] Moreover, the inflatable balloon member is able to block pipe members of various
geometry and sizes.
[0023] Also, an efficient and reliable blocking member configured to block pipe member is
achieved.
[0024] An inflatable balloon member provides a very flexible clocking means that also provides
a large contact surface (blocking surface) between the inflatable balloon member and
the pipe member. Hereby an effective blockage can be achieved. Moreover, an inflatable
balloon member allows particles and objects in sewage water to be enclosed by the
inflatable balloon member.
[0025] It may be an advantage that the blocking member is mechanical and therefore requires
no electricity (and hence no battery or connection to the mains is required).
[0026] As long as the actuation mechanism is configured to activate the actuation device
and hereby make the blocking member block the pipe member, the actuation mechanism
may be any suitable actuation mechanism operable upon contact with water.
[0027] The actuation mechanism may be a unit comprising several other members or a unit
connected to other members. The actuation mechanism is responsible for controlling
the flood protection device.
[0028] The flood protection device is configured to be arranged in the pipe member and be
removed from the pipe member without damaging the pipe member. This means that the
flood protection device can be arranged in a pipe member in a non-invasive way so
that the flood protection device can be removed or replaced when desired.
[0029] This is a major advantage compared to the prior art flood protection devices. Money,
time and inconvenience can be saved by using a flood protection device according to
the invention.
[0030] It may be an advantage that the flood protection device comprises a string member
configured to guide the flood protection device into a desired position within a pipe
member.
[0031] Hereby it is achieved that the flood protection device can be positioned in pipe
systems comprising a bending and another challenging structure.
[0032] The string member may be made in metal or plastic so that the required stiffness
is provided. At the same time a metal string member will allow the string member to
be bent if required. The cross section of the string member may be circular, oval,
square, rectangular or have any other suitable geometry.
[0033] Advantageously, the flood protection device comprises an unblocking member mechanically
connected to the string member, where the unblocking member is configured to unblock
the blocking member from blocking the pipe member when pulling or pushing the string
member. It may be an advantage that the string member comprises an inner string member
slidably arranged within an outer string member formed as a pipe. Hereby it is possible
both to pull the flood protection device with the outer string member and to pull
the flood protection device by using the inner string member by way of example. This
may in particular be beneficial in embodiments of the invention, in which the string
member is required to be configured to unblock the blocking member.
[0034] It may be an advantage that the flood protection device comprises a water detection
member configured to activate the actuation device and hereby make the blocking member
block the pipe member.
[0035] Hereby the presence of water can be detected and thus the actuation device of the
flood protection device can be activated in order to make the blocking member block
the pipe member as soon as water is detected by the water detection member.
[0036] It may be beneficial that the flood protection device comprises an electric water
detection member.
[0037] It may be an advantage that the flood protection device comprises a water detection
member arranged in the space of a shield member having an inner layer and an outer
layer, and that the shield member is provided with one or more apertures configured
to evacuate air or gas from the space of a shield member, and that the shield member
is configured to allow water to enter the space between the inner layer and the outer
layer through one or more apertures in the outer layer and to be discharged through
one or more apertures in the outer layer, and that the shield member is configured
in such a way that water will enter the shield member through one or more apertures
in the shield member and make the water detection member wet when the shield member
is submerged in water.
[0038] Hereby it is achieved that the flood protection device can be placed in a pipe member
with water flowing activating the blocking member and hereby blocking the pipe member.
At the same time the flood protection device is capable of blocking the pipe member
when water enters into the shield member when the flood protection device is submerged
into water (e.g. in case of water ingress through the pipe member). The flood protection
device will be activated only when submerged in water regardless of the direction
of the flow.
[0039] It may be an advantage that the water detection member is a compound (e.g. a tablet)
that is plugging a connection member (e.g. a pipe) while the water detection member
is kept dry, where the water detection member is configured to be dissolved or react
upon contact with water.
[0040] Hereby, a cheap, efficient and reliable water detection member can be achieved.
[0041] It may be an advantage that the inflatable balloon member is provided with at skid-proof
outer layer making the inflatable balloon member suitable for blocking pipe member
with a slippery inner surface.
[0042] It may be an advantage that the flood protection device is configured to be activated
by external means e.g. a remote control.
[0043] Hereby it would be possible to activate and/or test the flood protection device if
required.
[0044] The flood protection device according to the invention may be scaled in order to
fit into pipe members of various sizes.

Detailed description of the invention
[0046] It is referred in detail to the drawings for the purpose of illustrating a flood
protection device.
[0047] Fig. 1 is a schematic side view of a flood protection device 2. The flood protection
device 2 comprises an inflatable member 4 shaped as an inflatable balloon 4 (also
known as a bladder) that is in fluid communication with a gas cartridge 6 (e.g. compressed
gas such as Carbon Dioxide or Nitrogen). The flood protection device 2 moreover comprises
an activation mechanism 8 having a water detection member 10 arranged centrally in
a spherical double layered shield member 12.
[0048] The water detection member 10 is configured to activate the activation mechanism
8 when the water detection member 10 is in contact with water. The water detection
member 10 may be an electronic water detection member or a chemical compound (e.g.
a tablet) that is dissolved when being brought into contact with water.
[0049] A metal or plastic string member 22 is attached to the activation mechanism 8 of
the flood protection device 2. The string member 22 is configured to be used to position
and attached the flood protection device 2 in e.g. a drain (see Fig. 4 or Fig. 6)
or a toilet (see Fig. 5). The string member 22 can preferably be made in metal or
another material that is stiff enough to push the flood protection device 2 through
a bending (e.g. in a pipe bending) and flexible enough to allow for the required bending
of the string member 22 during positioning the flood protection device 2.
[0050] Fig 1. b) illustrates a close-up view of the shield member 12 shown in Fig. 1 a).
The shield member 12 is basically spherical and comprises an inner layer 14 arranged
within an outer layer 16. The water detection member 10 is symbolised by a black spherical.
A vent aperture 28 is provided in the top region of the inner layer 14 of the shield
member 12. The vent aperture 28 is configured to vent the shield member 12 (so that
air housed in the shield member 12 can be evacuated when water enters the shield member
12).
[0051] Water drops 50 may enter the shield member 12 through apertures 20 provided in the
outer layer 16. The water drops 50 will then stream down the outside surface of the
inner layer 14. Eventually, the water drops 50 will leave the space between the inner
layer 14 and the outer layer 16 through apertures 18. Accordingly, water drops 50
as illustrated in Fig. 1 b) will not activate the activation mechanism 8. Therefore,
the flood protection device 2 may be placed in a pipe, a drain or in a toilet without
being activated by water entering through the apertures 20 provided in the outer layer
16. This means that when the water is flowing freely during normal function, the flood
protection device 2 will not be activated.
[0052] However, when the shield member 12 is submerged in water, the water will enter the
space 32 within the inner layer 14 through the lower apertures 26 in the inner layer
14. Hereby the air housed in the space 32 within the inner layer 14 will be evacuated
through the vent aperture 28 and further through the upper apertures 20 in the outer
layer 16.
[0053] When the shield member 12 is submerged into water, the air housed in the space 32
within the inner layer 14 will gradually be evacuated through the vent aperture 28
and further through the upper apertures 20 in the outer layer 16 until all the air
in the space 32 within the inner layer 14 is displaced by the water entering the space
32 within the inner layer 14 through the lower apertures 26 in the inner layer 14.
Accordingly, the water detection member 10 will be wet and hence actuate the activation
mechanism 8 that will cause the balloon 4 to be inflated by gas from the gas cartridge
6. Hereby, the balloon 4 will block the pipe, drain or toilet into which the flood
protection device 2 is arranged. Hereby flood will be avoided.
[0054] It is preferred that the activation mechanism 8 is configured in such a way that
the string member 22 can be used to initiate an evacuation of the balloon 4 by pulling
the string member 22. It is possible to provide the activation mechanism 8 with a
build-in (e.g. mechanical) valve mechanism (not shown) configured to be activated
by pulling the string member 22. Hereby, it is possible to remove the flood protection
device 2 in an easy way by pulling the string member 22 while evacuating the balloon
4.
[0055] Fig. 2 a) illustrates a perspective cross-sectional view of a flood protection device
2 arranged in a pipe member 24. The flood protection device 2 is seen from its distal
end. It can be seen that the flood protection device 2 an inflatable rubber balloon
4.
[0056] In Fig. 2 b) the flood protection device 2 shown in Fig. 2 a) is seen in a state
in which the flood protection device 2 has been activated. It can be seen that the
inflatable rubber balloon 4 has been inflated. Accordingly, the balloon 4 will block
the pipe member 24 and therefore, the water has no longer access through the pipe
member 24 and flood damages will be avoided.
[0057] Fig. 2 c) illustrates a perspective cross-sectional view of the flood protection
device 2 shown in Fig. 2 a) seen from the opposite side (where the string member 22
is attached). It can be seen that the flood protection device 2 comprises a string
member 22 that is mechanically attached to an activation mechanism 8. Even though
not shown, it is preferred that the flood protection device 2 comprises an activation
mechanism that is configured in such a way that the string member 22 can be used to
initiate an evacuation of the balloon 4 by pulling the string member 22 or inflate
by pressurizing through the string member 22 (that may be formed as a pipe like illustrated
in Fig 9.
[0058] Fig. 2 d) illustrates a perspective cross-sectional view of the flood protection
device 2 shown in Fig. 2 c) in a state in which the balloon 4 has been inflated. Hence,
the pipe member 24 is blocked by the balloon 4 corresponding to the situation shown
in Fig. 2 b).
[0059] Fig. 3 a) illustrates a perspective view of a flood protection device 2 shown in
Fig. 2. The flood protection device 2 comprises an activation mechanism 8 arranged
within and surrounded by a cylindrical balloon member 4. A metal string member 22
is attached to the activation mechanism 8.
[0060] Fig. 3 b) illustrates a cross-sectional view of the flood protection device 2 centrally
arranged in a pipe member 24. The balloon member 4 is in a compressed state. However,
in Fig. 3 c) the balloon member 4 is inflated and thus the balloon member 4 blocks
the pipe member 24.
[0061] In Fig. 4 illustrates a cross-sectional view of a flood protection device 2 arranged
in a waste pipe 36. A grating 34 is arranged on the top of the draining frame 52 that
is arranged on a waste pipe 36. The flood protection device 2 has a string member
22 that is attached to an indentation 42 by means of a screw 40 that is screwed into
a threaded bore in the grating 34 having a number of openings.
[0062] Fig. 4b) illustrates a close-up view of the central portion of the grating 34. The
string member 22 of the flood protection device 2 detachable mounted to the grating
34. This means that the flood protection device 2 can be easily detached from the
grating 34 in case of replace of the flood protection device 2.
[0063] Fig. 4 c) illustrates a close-up view of the flood protection device 2 shown in Fig.
4 a) in a state in which the balloon member 4 has been inflated. Accordingly, the
balloon member 4 blocks the waste pipe 36. It can be seen that the region of the waste
pipe 36 below the balloon member 4 is filled with water 44. Therefore, the flood protection
device 2 has prevented water ingress through the waste pipe 36.
[0064] The flood protection device 2 is configured to automatically inflate the balloon
member 4 and hereby block the waste pipe 36 when the water detection member (not shown)
of the flood protection device 2 becomes wet. Therefore, the balloon member 4 is inflated
when the raising water 44 in the waste pipe 36 gets into contact with the water detection
member (not shown) of the flood protection device 2.
[0065] It should be underlined that the string member 22 may be attached to the grating
34 simply by applying a hook or bending the string member 22 and hereby attaching
the string member to the grating 34 like shown in Fig. 9.
[0066] Fig. 5 illustrates a flood protection device 2 being arranged in a toilet 46. In
Fig. 5 a) the flood protection device 2 is being prepared to be arranged in the lower
region of the toilet 46. The string member 22 of the flood protection device 2 is
flexible so that the flood protection device 2 can enter the pipe system of the toilet
46. In Fig. 5 b) the flood protection device 2 has been arranged in the main pipe
of the toilet 46. The distal end of the string member 22 is detachable attached to
the toilet 46 by means of a wedge 48. It is important to underline that the string
member 22 may be attached to the toilet 46 by other means. It is preferred that the
string member 22 is attached to the toilet 46 in a manner that allows for easy and
fast replacement of the flood protection device 2.
[0067] The balloon member 4 is provided with a string member 22, by means of which it is
possible to evacuate the gas in the balloon member 4 simply by pulling the string
member 22. Accordingly, the flood protection device 2 can be removed by pulling the
string member 22 first in order to evacuate the gas (e.g. air) in the balloon member
4 and hereafter by pulling the flood protection device 2 out of the toilet 46. It
is preferred that the string member 22 is made in a stiff material e.g. metal that
makes it possible to push the flood protection device 2 into the pipe system of e.g.
a toilet like illustrated in Fig. 5.
[0068] In Fig. 5 c) the balloon member 4 of the flood protection device 2 has been inflated
and blocks the water 44 in the lower region of the pipe system and the flood protection
device 2 prevents the water 44 from rising further. Hereby the flood protection device
2 prevents water ingress through the pipe system of the toilet 46.
[0069] Fig. 6 illustrates a flood protection device 2 arranged in a waste pipe 36 of a drain
comprising a grating 34 that is arranged on the top of and received by a corresponding
draining frame 52. The flood protection device 2 comprises a long thin string member
22 that is detachable attached to the centre of the grating 34 by means of a hook
72. Accordingly, the flood protection device 2 can easily be removed from the drain
by removing the hook 72 from the grating 34.
[0070] The flood protection device 2 is arranged in the waste pipe 36 and therefore it is
configured to prevent water ingress through the waste pipe system 36.
[0071] Fig. 7 illustrates a cut-away view of a pipe 54 in which a flood protection device
2 is arranged. The pipe 54 is connected to a pipe 58 having an opening 60, through
which there is access to the pipe 54. The string member 22 of the flood protection
device 2 can be used to push the flood protection device 2 into the desired position
within the pipe 54. The inflatable balloon member 4 of the flood protection device
2 can be seen through the cut away 56 in the pipe 54. The string member 22 can easily
be detachable attached to the pipe 58 e.g. by bending the string member 22 around
the pipe 54 (not shown). The flood protection device 2 is suitable for being detachable
mounted in various types of pipe systems even pipe systems having challenging structures
such as bending.
[0072] Accordingly, the flood protection device 2 can be detachable mounted and prevent
water ingress through various pipe systems.
[0073] Fig. 8 a) illustrates another schematic view of the flood protection device 2 shown
in Fig. 1 a). The flood protection device 2 comprises an inflatable member 4 shaped
as an inflatable balloon 4 being in fluid communication with a gas cartridge 6 that
comprises compressed gas (e.g. Carbon Dioxide or Nitrogen). The interior of the activation
mechanism 8 is indicated. It can be seen that the gas from the gas cartridge 6 can
flow through a number of gas flow lines 68, 68', 68", 68"'. The gas from the gas cartridge
6 can flow into the housing of the activation mechanism 8 via a first gas flow line
68'.
[0074] A water detection member 10 arranged centrally in a spherical double layered shield
member 12 prevents the gas from getting access to the central portion of the housing
of the activation mechanism 8 via a second gas flow line 68'. When the water detection
member 10 (e.g. a water-soluble tablet) is exposed to water, the water detection member
10 will no longer 12 prevents the gas from the gas cartridge 6 from getting access
to the central portion of the housing of the activation mechanism 8 via a second gas
flow line 68'.
[0075] Accordingly, when the water detection member 10 is exposed to water the gas from
the gas cartridge 6 will flow into the inflatable balloon 4 via the first gas flow
line 68 to the second gas flow line 68' and further to the third gas flow line 68".
A valve member 66 comprising a spring member 62 and a ball member 64 is arranged within
the housing of the activation mechanism 8.
[0076] The valve 66 is configured to let out gas in case that a high pressure is built up
in the inflatable balloon 4. If a high pressure builds up in the inflatable balloon
4, the pressure causes the ball member 64 to compress the spring member 62 and hereby
the gas is allowed to escape out of the housing of the activation mechanism 8 via
the fourth gas flow line 68"'.
[0077] The flood protection device 2 comprises a string member 22 that can be used to degas
the inflatable balloon 4. Degassing of the inflatable balloon 4 is done simply by
pulling the string member 22 so that the spring member 62 is moved upwardly. Hereby
the ball member 64 will no longer be pressed against the valve mouth 70. Accordingly,
the gass from the inflatable balloon 4 will be degassed through the third gas flow
line 68" and the fourth gas flow line 68"'.
[0078] It is preferred that the gas cartridge 6 comprises just enough gas to inflate the
inflatable balloon 4. Hereby it is achieved that the inflatable balloon 4 can be degased
at the moment the string member 22 moves the spring member 62 upwards. If the gas
cartridge 6 comprises much more gas than it is required to inflate the inflatable
balloon 4, the pressure from the gas in the gas cartridge 6 will continue to keep
the inflatable balloon 4 inflated until the pressure within the gas cartridge 6 is
reduced to a level that allows the inflatable balloon 4 to be emptied via the valve
66.
[0079] Fig. 8 b) illustrates another close-up view of the shield member 12 shown in Fig.
1 b). The shield member 12 is turned upside down and comprises an inner layer 14 arranged
within an outer layer 16.
[0080] It can be seen that water drops 50 entering the shield member 12 will leave the shield
member 12 through the openings 20, 28 in the inner layer 14 and the outer layer 16
of the shield member 12.
[0081] Therefore, water drops 50 as illustrated in Fig. 8 b) will not activate the activation
mechanism 8. Hence, the flood protection device 2 may be placed in a pipe, a drain
or in a toilet without being activated by water entering through the apertures 18,
26 provided in the inner layer 14 and the outer layer 16 of the shield member 12.
[0082] In order to activate the activation mechanism 8 it is required that the shield member
12 is submerged into water. When the shield member 12 is submerged into water, the
water will enter the space 32 within the inner layer 14 through the apertures in the
apertures 20, 28 provided in the inner layer 14 and the outer layer 16 of the shield
member 12. The air housed in the space 32 within the inner layer 14 will gradually
be evacuated through the apertures 18, 26 until all the air in the space 32 within
the inner layer 14 is displaced by the water entering the space 32.
[0083] Accordingly, the water detection member 10 will be wet and hence actuate the activation
mechanism 8 that will cause the balloon 4 to be inflated by gas from the gas cartridge
6. Hereby, the balloon 4 will block the pipe, drain or toilet into which the flood
protection device 2 is arranged. Hereby flood can be avoided.
[0084] Fig. 9 a) illustrates a flood protection device 2 almost similar to the one shown
in Fig. 4 a). The flood protection device 2 is, however, attached to the grating 34
by means of a hook 72.
[0085] Fig. 9 b) illustrates another flood protection device 2. The flood protection device
2 is configured to be manually inflated. A gas cartridge 6 is attached to the distal
end of a string member 22 shaped as a pipe. Hereby an inflatable member 4 of the flood
protection device 2 can be manually inflated in order to block the waste pipe 36.
