[0001] The present invention relates to a lower heat-generating device for a deck in a ship.
More particularly, the present invention relates to a lower heat-generating device
for a deck in a ship, which is exothermically mounted below the ship deck so that
safety accidents due to freezing from the bitterly cold weather are prevented from
occurring, which can be additionally installed at an existing structure so that an
economic efficiency is ensured, which is installed independently so that maintenance,
repair and management are facilitated, and which is installed below, but not above
a structure so that inconvenience is not caused to a walker and a worker during the
walk and work.
[0002] In general, a structure such as a stairway or a corridor installed on a ship or a
marine structure is made of a ferrous material. However, in case of an iron stairway
installed on a ship or a marine structure that is exposed to the same cold weather
as the polar region for a long period of time, there is caused a problem in that a
footplate of the stairway is prone to be frozen so that a walker and a worker are
exposed to safety accidents.
[0003] In order to address and solve this problem, heat-generating devices are disclosed
which prevent the footplate of the stairway from being frozen. However, such conventional
heat-generating devices entail a problem in that since maintenance and repair of the
entire heat-generating device is required when its erroneous operation or breakage
occurs, the stairway may be frozen during the maintenance and repair period, thereby
making it difficult to use the stairway and increasing the maintenance and repair
cost. Furthermore, in the case where the heat-generating device is installed at an
existing structure, a user suffers from an inconvenience having to reconstructing
to install the heat-generating device after dismantling a stairway or a corridor,
as well as the conventional heat-generating device has a disadvantage in that it is
installed above, but not below the structure so that inconvenience is caused to a
walker and a worker during the walk and work.
[0005] Starting therefrom, the present invention was made to solve the aforementioned problem
occurring in the prior art, and it is an object of the present invention to adapt
the heat-generating device for a deck in a ship, to be exothermically mounted below
the ship deck and providing a good heat transfer, so that safety accidents due to
freezing from the bitterly cold weather are prevented from occurring, which can be
additionally installed at an existing structure so that an economic efficiency is
ensured, which is installed independently so that maintenance, repair and management
are facilitated, and which is installed below, but not above a structure so that inconvenience
is not caused to a walker and a worker during the walk and work.
[0006] To accomplish the above object, in accordance with an embodiment of the present invention,
there is provided a lower heat-generating device for a deck in a ship, including:
an enclosure member having a filling space defined therein and a plurality of fastening
holes formed on a bottom surface thereof, the enclosure member being opened at a top

and configured to transfer heat to the ship deck positioned above the heating cable;
a fixing member disposed on the heating cable and configured to securely fix the heating
cable on the heat-insulating member so that the heating cable is held in position;
and a controller mounted at the outside of the enclosure member and electrically connected
to the heating cable, the controller being configured to control the generation of
heat from the heating cable and the supply of electric power.
[0007] Further the lower heat-generating device includes a heat diffusion member configured
to be filled in an air layer formed between the underside of the ship deck and the
top surface of the fixing member to exhibit a heat-insulating effect, the heat diffusion
member having a shape corresponding to that of the air layer.
[0008] In accordance with a preferable embodiment, the heat-insulating member includes one
or more concave depressions formed at a region of the air layer where the heating
cable is not arranged so as to increase the volume of the air layer, the heat diffusion
member being formed and filled to have a shape corresponding to that of the air layer.
[0009] The lower heat-generating device for a deck in a ship in accordance with a preferred
embodiment of the present invention as constructed above has the following advantageous
effects.
[0010] The lower heat-generating device is exothermically mounted below the ship deck so
that safety accidents due to freezing from the bitterly cold weather can be prevented
from occurring. In addition, the lower heat-generating device can be additionally
installed at an existing structure so that an economic efficiency is ensured, and
can be installed independently so that maintenance, repair and management are facilitated.
Further, the lower heat-generating device is installed below, but not above a structure
so that inconvenience is not caused to a walker and a worker during the walk and work.
[0011] The above objects, other features and advantages of the present invention will become

[0012] The matters defined in the description, such as the detailed construction and elements,
are nothing but specific details provided to assist those of ordinary skill in the
art in a comprehensive understanding of the invention, and the present invention is
not limited to the embodiments disclosed hereinafter.
[0013] Fig. 1 is an exploded perspective view showing a lower heat-generating device for
a deck in a ship, Fig. 2 is a cross-sectional view showing a lower heat-generating
device for a deck in a ship, and Fig. 3 is a schematic diagrammatic view showing a
use state in which a lower heat-generating device for a deck in a ship.
[0014] The lower heat-generating device for a deck in a ship includes: a enclosure member
10 having a filling space 11 defined therein and a plurality of fastening holes 12
formed on a bottom surface thereof, the enclosure member being opened at a top thereof;
a heat-insulating member 20 configured to be filled in the filling space 11 of the
enclosure member; a heating cable 30 exothermically arranged on the heat-insulating
member 20 and configured to transfer heat to the ship deck positioned above the heating
cable; a fixing member 40 disposed on the heating cable 30 and configured to securely
fix the heating cable 30 on the heat-insulating member 20 so that the heating cable
is held in position; and a controller 50 mounted at the outside of the enclosure member
10 and electrically connected to the heating cable 30, the controller being configured
to control the generation of heat from the heating cable 30 and the supply of electric
power.
[0015] Hereinafter, constituent elements and their connection relationship of the lower
heat-generating device for a deck in a ship will be described in detail with reference
to Figs. 1 and 2.
[0016] Herein, the enclosure member 10 is an element where constituent elements which will
be described later are filled and installed, and that serves to form the entire outer
appearance of the lower heat-generating device 1. The enclosure member 10 has a filling
space 11 defined therein and a plurality of fastening holes 12 formed on a bottom
surface thereof. In addition, the enclosure member 10 is opened at a top thereof.
[0017] The enclosure member 10 may be formed in a quadrangular shape having various sizes.
The enclosure member 10 is formed to have the filling space 11 therein in such a manner
that four sidewalls having a predetermined height protrudingly extends vertically
upwardly from a bottom of the enclosure member 10. The fastening holes 12 serves to
allow fixing bolts weldingly fixed to the underside of the deck to which the lower
heat-generating device 1 is mounted to be fastened with fixing nuts on the underside
of the enclosure member 10 therethrough. In this case, the fastening holes 12 are
not formed at regions where the heating cable 30 is arranged. In addition, the aforementioned
connecting hole 13 serves to allow a connecting cable 51 connected to the controller
50 which will be described later to be introduced into the enclosure member 10 therethrough.
[0018] The heat-insulating member 20 is filled within the filling space 11 of the enclosure
member 10 as described above, and serves to prevent heat released from the heating
cable 30 from being transferred to the bottom, but not in the direction of the ship
deck. In other words, the heat-insulating member 20 prevents heat from being released
to the bottom and releases the heat from the heating cable to only the upper deck
so as to increase the heat efficiency of the lower heat-generating device. The heat-insulating
member 20 preferably employs a conventional heat-insulating material for heat release
and water proof purpose. In this case, a top surface of the heat-insulating member
20 brought into direct contact with the heating cable 30 is preferably coated with
a refractory material to prevent a fire from occurring due to heat released from the
heating cable 30.
[0019] Meanwhile, the heating cable 30 is exothermically arranged on the heat-insulating
member 20 filled in the filling space 11, and serves to generate heat by itself through
the electric power supplied under the control of the controller 50 so that the generated
heat is transferred to the ship deck to prevent the ship deck from being frozen.
[0020] The heating cable 30 employs a conventional heating cable 30, and the heat-insulating
member 20 on which the heating cable 30 is seated may have a groove (not shown) formed
thereon to correspond to the shape of the heating cable 30. In the case where the
top surface of the heat-insulating member 20 is not coated with a refractory material,
a separate refractory film may be interposed between the heat-insulating member 20
and the heating cable 30.
[0021] In addition, the fixing member 40 is provided on the heating cable 30 seated on the
heat-insulating member 20. The fixing member 40 serves to securely fix the heating
cable 30 on the heat-insulating member 20. The fixing member 40 employs a conventional
aluminum tape, and is closely attached to the heating cable 30 without any spacing
so that the shape of the heating cable 30 seated on the heat-insulating member 20
is exposed to the outside.
[0022] In the meantime, the controller 50 is mounted at the outside of the enclosure member
10 and is electrically connected to the heating cable 30 by means of the connecting
cable 51 so that the controller controls the generation of heat from the heating cable
30 and the supply of electric power. The controller 50 is mounted at a rail of the
ship deck by one relative to three enclosure members 10 as shown in Fig. 3. In this
case, the heating cables 30 of adjacent enclosure members 10 may be designed to be
connected to one another so that the generation of heat from the heating cable 30
and the supply of electric power can be controlled by a single controller 50. Alternatively,
a temperature sensor may be additionally mounted at the controller 50 so that electric
power can be supplied to the heating cable 30 below a predetermined temperature, and
the supply of electric power can be interrupted above the predetermined temperature.
[0023] Hereinafter, the entire installation method of the lower heat-generating device for
a deck in a ship in accordance with an embodiment of the present invention will be
described in detail with reference to Fig. 3
[0024] First, the heat-insulating member 20 is filled in the filling space 11 of the enclosure
member 10, and the heating cable 30 is arranged on the filled heat-insulating member
20. Thereafter, the fixing member 40 is attached to the heating cable 30 to securely
fix the heating cable 30 on the heat-insulating member 20 so as to be held in position.
[0025] Then, the connecting cable 51 connected to the controller 50 is inserted into the
connecting hole 13 formed at one sidewall of the enclosure member 10 so that the connecting
cable 51 is electrically connected to the heating cable 30.
[0026] Thereafter, fixing bolts weldingly fixed vertically to the underside of a corridor
of the ship to be heated are inserted at lower ends thereof into the fastening holes
12 and protruded to the outside through fastening holes 12. At this time, the lower
ends of the fixing bolts protruded to the outside through the fastening holes 12 are
firmly fastened with fixing nuts.
[0027] In the above method, the lower heat-generating device 1 is mounted on the entire
underside of the corridor of the ship and the generation of heat therefrom and the
supply of electric power can be controlled by the controller 50. In the meantime,
Fig. 4 is a cross-sectional view showing a lower heat-generating device for a deck
in a ship in accordance with an embodiment of the present invention, and Fig. 5 is
a cross-sectional view showing a lower heat-generating device for a deck in a ship
in accordance with another embodiment of the present invention.
[0028] An air layer 60 is formed between the underside of the ship deck and the top surface
of the lower heat-generating device. The air layer 60 serves a heat-insulating element
that prevents external cold air from taking internal heat. A heat diffusion member
80 may be filled in the air layer 60 in such a manner that the shape of the heat diffusion
member 80 corresponds to that of the air layer 60 as shown in Fig. 4. The heat diffusion
member 80 serves to rapidly transfer heat released from the heating cable 30 to the
ship deck.
[0029] In addition, the heat-insulating member 20 may further include a plurality of concave
depressions 70 formed at a region of the air layer 60 where the heating cable is not
arranged so as to increase the volume of the air layer 60 and thus improve the heat-insulating
effect as shown in Fig. 5. In this case, the heat diffusion member 80 is formed and
filled to have a shape corresponding to that of the air layer, and also serves to
rapidly transfer heat released from the heating cable 30 to the ship deck. While the
present invention has been described in connection with the specific embodiments illustrated
in the drawings, they are merely illustrative, and the invention is not limited to
these embodiments. It is to be understood that various equivalent modifications and
variations of the embodiments can be made by a person having an ordinary skill in
the art without departing from the scope of the present claimed invention.
[0030] Therefore, the true technical scope of the present invention should not be defined
by the above-mentioned embodiments but should be defined by the appended claims and
equivalents thereof.
[0031] As described above, the lower heat-generating device for a deck in a ship in accordance
with an embodiment of the present invention can be applied to a bottom portion of
a deck of a ship or a marine structure that is exposed to the same cold weather as
the polar region for a long period of time so as to prevent the deck from being frozen.
