[0001] The present invention relates to an aquatic rescue vehicle, self-propelled by turbines,
arranged at the distal ends of a substantially U-shaped body and a rescue method in
which such a vehicle intervenes.
Background
[0002] Self-propelled U-shaped rescue vehicles have been shown to be particularly effective
in rescue operations for victims in seas, rivers or reservoirs of dams and are currently
a highly sought-after alternative by the market to traditional rescue means, namely
lifebuoys.
[0003] The speed of the intervention and the rescue coupled with the possibility of remotely
controlling the rescue means are the reasons for the aforementioned demand that is
registered either by the owners of recreational boats or professionals or by the maritime
authorities or the concessionaires of bathing areas.
[0004] The vehicle described and disclosed in
EP 3041733 B1 is considered the state of the art closest to the present invention. A U-shaped vehicle
self-propelled by turbines arranged at the distal ends of the flaps is disclosed.
However, the most critical part of the rescue, which is the deposition of the human
being in the vehicle and its removal from the water, as well as the speed of the rescue,
are aspects not considered in the state of the art of the applicant's knowledge and
the object of the present invention.
Object of the invention
[0005] The present invention aims to provide this type of rescue vehicles with greater operability
and safety.
[0006] It was found that an important factor in rescue operations is the removal of the
human being that is injured or in distress from the aquatic environment. It is the
object of the present invention to provide a self-propelled water vehicle in which
the approach and deposition or self-deposition of the injured person in the rescue
vehicle, as well as the rapid removal of the immersed part of the injured person from
the water is effectively achieved.
[0007] Rescues take place under the most varied sea conditions and a rescue vehicle must
respond to the most demanding rescue conditions, namely sea conditions with strong
waves and surf that offer strong resistance to the progression of a vehicle travelling
on the water surface. It is intended with this invention to reduce the friction or
resistance to the progression of the U-shaped vehicle on the water surface in order
to achieve higher operating speeds and a longer battery life.
[0008] Another objective of the invention is to facilitate the access of a user, who may
be a lifeguard, an accident victim or both, to the vehicle, preventing entry into
the vehicle from being hampered by any obstacle such as a boat's rail.
[0009] The invention also intends to be a methodology for rescuing the crew of a vessel
that has to be evacuated. Traditionally the crew of a struggling sailboat is rescued
by aerial means, for example a helicopter, by launching a cable from an aerial means,
directly to the deck where the people to be rescued are located. The crew will then
cling to the cable to be lifted into the air. It appears that in choppy sea conditions,
rescue through this process is challenging due to the difficulty of aligning the helicopter
with the cable and the vessel. The present invention allows the crew to be rescued
by the same cable, suspended from the air, not over the vessel that has to be evacuated,
but over the rescue vehicle, whose geographical position is controlled remotely from
the helicopter. It is thus easier to align the helicopter with the rescue vehicle
and the castaways, as their position is controlled remotely since they are attached
to the rescue vehicle and its position is controlled from the air.
[0010] According to the present invention, a water rescue vehicle is provided, as defined
in claim 1.
[0011] For a better understanding of the present invention, a preferred embodiment is now
described, purely as a nonlimiting example, with reference to the accompanying drawings,
in which:
- Figure 1 shows a schematic top view of a water rescue vehicle according to the invention;
- Figure 2 shows a schematic two-dimensional top view of the water rescue vehicle, according
to the invention;
- Figure 3 shows a schematic sectional view of the water rescue vehicle according to
the invention;
- Figure 4 shows a schematic sectional view of the water rescue vehicle, according to
the invention with a human in a supine position;
- Figure 5 shows a schematic sectional view of the water rescue vehicle, according to
the invention with a human being in the ventral position;
- Figure 6 shows a schematic sectional view of the water rescue vehicle, according to
the invention, with two humans;
- Figure 7 shows a schematic view of a scenario for rescuing a number of humans in the
water.
[0012] With reference to these figures, an aquatic rescue vehicle is shown, according to
the invention.
[0013] In particular, Figure 1 shows a rescue vehicle in the aquatic environment 1, self-propelled.
[0014] The invention comprises a main body 101, constituted by a U-shaped bow portion 2,
from which two flap portions 3 are projected laterally at the distal ends 4, from
which propulsion turbines 5 are housed.
[0015] Not shown in the figures, is how the main body also houses electric batteries, which
can be charged by induction.
[0016] The interior space of the U-shaped body is occupied by a support/slide membrane 6,
able to receive the body of a human being on the surface of the water.
[0017] It is a primary objective of the invention to facilitate human entry into the rescue
vehicle and provide for its rapid removal from the water. The objective is achieved
by varying the specific volume of the different parts of the vehicle in such a way
that the median longitudinal plane of the vehicle, coinciding with the longitudinal
plane formed by the support/sliding membrane (A, A'), is oblique to the mean plane
of the water surface (B, B'). In this way, the castaway who approaches the vehicle
not only does not find any impediment to entering it, but also benefits from a slightly
inclined flat surface that requires less effort to approach by a user. In addition,
when the propulsion starts, the vehicle presents a positive incidence angle towards
the water surface, which causes a force to be withdrawn from the human body still
immersed, in the initial moments of a rescue, to allow, in the moments following on
from this, a displacement with much less friction than with a U-shaped vehicle without
a membrane. In this way, i) it is able to relieve the tension of the rescue in the
initial moments, because the entire body of the castaway is removed from the water
with the help of the vehicle's own propulsion and ii) it has a speed of displacement
that allows a greater number of displacements for the same time of battery discharge.
It is the positive angle of incidence, combined with the position of the membrane
6, which allows a displacement, by sliding, similar to that of a water skate, faster
and with less friction compared to similar rescue vehicles of the state of the art.
[0018] According to the invention, the specific volume of the bow portion 2, is greater
than the specific volume of the distal end portions 4, of the side flaps 3, the vehicle
assuming, when willing to float on the water surface, a position in which, the longitudinal
plane formed by the support/sliding membrane 6, is oblique with respect to the plane
of the water surface, with the distal end portions 4 of the side flaps 3, from semi-submerged
to fully submerged in the water and the bow portion 2, total to partially emerged.
[0019] Advantageously, the rescue vehicle has a volume such that, when the vehicle moves
to the surface of the water, the head of the vehicle user, which is positioned close
to the bow, is protected from water, in order to facilitate breathing.
[0020] Preferably, the rescue vehicle according to the invention has handles 8, on the entire
periphery of the vehicle.
[0021] According to one aspect of the invention, the support/sliding membrane 6 is made
of a material belonging to the group of materials consisting of flexible, rigid and
semi-rigid materials.
[0022] The rescue vehicle of the invention provides that the supporting/sliding membrane
is detachable, by means of rings/stretchers 601. According to another option for embodiment
of the invention, the support/slide membrane is integral with the main body of the
vehicle.
[0023] Advantageously, the vehicle of the invention has speed controllers on the main body
of the vehicle (not shown) in the form of buttons or levers. It can also be controlled
remotely from a remote control that communicates with the vehicle via the control/communication
module 7.
[0024] In a possible embodiment of the invention, the self-propelled aquatic rescue vehicle
is inflatable. On the other hand, it can be manufactured in flexible, rigid or semi-rigid
material.
[0025] Advantageously, the self-propelled aquatic rescue vehicle incorporates a GPS-like
geographical location system.
[0026] Also, an advantage in the aquatic rescue vehicle, the vehicle's batteries can be
charged by induction.
[0027] In fig. 2 the vehicle of the invention is shown as a plan: the U-shaped bow portion
2 is rounded to overcome the progression in the aquatic environment and the distal
extremity portions 4, on the side flaps 3, are presented with a greater specific volume
than that of the bow portion, and the turbines 5 that are housed there contribute
to this difference in the specific volume.
[0028] Figs. 3 to 6 show the vehicle of the invention when occupied by one or two human
beings (10, 11, 12), the oblique positioning of the longitudinal plane of the membrane
(A, A') being visible in relation to the plane of the water surface (B, B') which
remains substantially identical in either situation, as well as whether the vehicle
is at rest or in motion. This is achieved by balancing the specific volume of the
different portions of the vehicle, taking into account the buoyancy.
[0029] The invention allows the execution of a rescue method especially useful when it comes
to rescue a group of human beings in difficulties in the aquatic environment, as illustrated
in Fig. 7. The motivation for the invention came from rescuing the crew of sailboats
in distress in the high seas. In fact, in these cases, it is often difficult to place
a rescue cable suspended from aerial means on a sailboat in distress at sea. This
is due to the fact that the sea, in altering conditions, permanently modifies the
vessel's relative position, a circumstance which adds to the difficulty of the constantly
changing position of the mast. In these conditions the vehicle of the invention lends
itself to the execution of a rescue method that comprises the following steps:
- provides a rescue vehicle 1, with a number of handles 8, floating on the surface of
the water,
- allows castaways on the surface of the water to cling to the handles 8 of the rescue
vehicle,
- aligns the rescue cable 71 arranged from an air rescue means with the rescue vehicle
1,
- corrects, in real time, the alignment of the rescue vehicle with the cable placed
from the air through the remote control that communicates with the electronic telecommunications
module 7,
- proceeds to the rescue.
[0030] Finally, it is clear that the water rescue vehicle described and illustrated here
as well as the rescue method can be modified and varied without departing from the
scope of protection of the present invention, as defined in the appended claims.
