BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show a case where a floating structure is a ship as an embodiment of the present invention. The water line D. The metal fitting 6 is attached to the vicinity of the center of the ceiling of each compartment 1 formed inside the portion of L or less, and the bag body 2 that is sized to be pressed against the inner surface of each compartment 1 when inflated is in a contracted state. The bag body 2 is housed between the mounting hardware 6 and the ceiling, and is in the ceiling portion of each section 1.
A gas cylinder 3 as a compressed gas supply means is held between the mounting hardware 6 and the ceiling at a position near the storage part of the container, the inlet of the bag 2 and the gas cylinder 3 are provided with an electromagnetic valve 5 as an opening / closing valve. When the solenoid valve 5 of each of the gas supply pipes 4 is opened, the compressed gas 7 is supplied from the gas cylinder 3 to the corresponding bag body 2 and the whole area of the corresponding compartment 1 is connected. The bag body 2 is inflated.

The bag 2 is made of an elastic material such as rubber, and has strength enough not to be damaged even if it touches a protrusion in the compartment 1. In addition, each gas cylinder 3 has a compressed gas amount capable of quickly inflating the bag body 2 over the entire area of the compartment 1, and the internal pressure of the expanded bag body 2 is the head pressure acting on the compartment 1. The volume of the compartment 1 in which each bag 2 is to be inflated and the water line D. The supply amount of the compressed gas 7 can be adjusted according to the depth of L or less.

Further, an inundation detector 8 for detecting inundation and emitting a signal is installed at the inner bottom of each compartment 1, and based on the inundation detection signal from the inundation sensor 8, for example, in each compartment. Flooded compartment display portion 9 displaying the flooded compartment 1 so as to be able to identify the flooded compartment 1 by turning on the corresponding flood warning lamp 10, and each bag body 2 arranged in each compartment 1
A control panel 12 including a switch 11 for individually giving an opening command to the solenoid valve 5 of the gas supply pipe 4 connected to the
Are provided in a control room (not shown).

As shown in detail in FIG. 3, the water immersion sensor 8 includes a recess 13 provided on the floor surface of the compartment 1 and an arm member 14 in which an intermediate portion is swingably supported by a rotary shaft 15. The float 16 is attached to one end, and the operating piece 17a is attached to the other end. When the float 16 is displaced upward in the recess 13 about the rotary shaft 15, the operating piece 17a is lowered to move the switch 17a. The contact is closed to send out a water infiltration detection signal. Therefore,
When the section 1 is flooded, water flows into the recess 9, and the float 12 is pushed up from the initial state shown by the solid line in FIG. 3 as shown by the chain double-dashed line in FIG. 3 as the water level in the recess 9 rises. And the operating piece 17a at the other end of the arm member 14 that descends as the float 16 rises is the switch 1
7 will be activated and a flooding detection signal will be emitted.

Due to a grounding, a collision with another ship, a collision of an object, or the like, the water line D. When the hull skin I of the portion of L or less is damaged and the damaged portion 18 as shown in FIGS. 1 and 2 is generated, the compartment 1 inside the portion where the damaged portion 18 is generated is generated.
Water will be flooded inside. The inundation detector 8 detects the inundation of the compartment 1, and the inundation warning lamp 10 corresponding to the compartment 1 of the control panel 12 is turned on to promptly notify the inundation of the compartment 1 to the inundated compartment 1. Since it can be quickly identified, the switch 11 of the control panel 12 corresponding to the submerged compartment 1 is operated to open the solenoid valve 5 of the gas supply pipe 4 connected to the bag 2 stored in the submerged compartment 1. When operated, the compressed gas 7 is supplied from the gas cylinder 3 to the bag body 2 as shown by the chain double-dashed lines in FIGS. 1 and 2, so that the bag body 2 is quickly spread over the entire space of the submerged compartment 1. Inflated to. At this time, since the internal pressure of the bag body 2 is set to a required pressure higher than the water head pressure acting on the compartment 1, the internal pressure of the bag body 2 expanded with respect to the damaged portion 18 in which the water is inundated. Because it will be pressed more strongly due to
The damaged portion 18 is closed so that the water can be stopped.

As described above, when the damaged portion 18 is generated in the hull outer plate I and the corresponding compartment 1 is flooded, the solenoid valve 5 of the gas supply pipe 4 is simply opened to save labor and time. It is possible to quickly inflate the bag body 2 in the submerged compartment 1 without needing to cover the damaged portion 18 with the inflated bag body 2 and prevent water from being inundated in a short time. At the same time, since the bag body 2 inflated by the compressed gas 7 exists in the compartment 1 corresponding to the damaged portion 18, the buoyancy of the compartment 2 can be secured, the balance of the hull is not lost, and the navigation of the ship is prevented. It is possible to suppress deterioration of performance.

Further, since the gas cylinders 3 are individually connected to the bags 2 provided in each of the compartments 1, the compressed gas supply portions are arranged in a distributed manner, which results in high resistance (damage). The ability to limit the damage to the main functions and performance when receiving the damage and prevent the complete loss) can be obtained.

Further, the operator can easily and quickly recognize which submerged section 1 the submersion is to be made by monitoring the submerged warning lamp 10 on the submerged section display section 9 on the control panel 12, and the illuminated submersion warning lamp is lit. By operating the switch 11 corresponding to the submerged section 1 that is easily identified from 10, the bag body 2 can be inflated in the submerged section 1 to prevent the submersion, so that the submerged section 1 can be prevented from being submerged. The labor and time required can be reduced.

Next, FIG. 4 shows another embodiment of the present invention. In the structure similar to that of the ship as the floating structure shown in FIGS. 1 to 3, the bag body and the refractory material are used. As the bag body 2a made of a product, when a fire occurs in the compartment 1, the bag body 2a equipped in the fire compartment 1 can be extinguished by inflating the whole area of the compartment 1.

To this end, a fire detector 19 for detecting a fire and emitting a signal is provided at a required position of each section 1, for example, a ceiling portion, and further, from a flood sensor 8 arranged in each section 1. The control panel 12a is provided with a switch 11 for opening and closing the solenoid valve 5 of the gas supply pipe 4 connected to the bag body 2a of each section 1 and the submerged section display unit 9 for displaying the submersion section 1 based on the water detection signal. On the basis of the fire detection signal from the fire detector 19, for example, a fire is displayed so that the compartment 1 in which the fire has occurred can be specified by turning on the fire warning lamp 21 individually corresponding to each compartment 1. The control panel 12a including the generation section display unit 20 is provided. Further, the submerged compartment display section 9 for displaying the submerged compartment 1 based on the submersion detection signal from the submerged sensor 8 arranged in each compartment 1 and the gas supply pipe 4 connected to the bag body 2a of each compartment 1 are provided. A switch 11 for opening the solenoid valve 5 is provided on the control panel 12a.

Other configurations are the same as those shown in FIGS. 1 to 3, and the same components are designated by the same reference numerals.

According to the present embodiment, a section 1 (see FIG.
If there is a fire in the leftmost section 1),
A fire detector 19 provided therein detects a fire and emits a fire detection signal, and the fire warning lamp 21 of the control panel 12a corresponding to the fire occurrence section 1 is turned on based on the signal, The operator can immediately know the fire occurrence and can quickly identify in which section 1 the fire occurred. Therefore, the operator operates the switch 11 at the lower end of the control panel 12a corresponding to the fire occurrence section 1 to open the solenoid valve 5 of the gas supply pipe 4 provided in the fire occurrence section 1, and 4, the compressed gas 7 is supplied from the gas cylinder 3 to the bag 2a so that the bag 2a made of a refractory material is rapidly expanded over the entire space of the fire-generating compartment 1. Let them extinguish the fire. At this time, since the fire can be extinguished without using water or a fire extinguishing agent as in the conventional case, it is possible to eliminate the need for time-consuming post-processing work such as draining water after the fire extinguishing and cleaning the fire extinguishing agent. It is possible to reduce the labor and time required for the fire prevention work.

When the outer shell I of the ship is damaged and water is submerged in the compartment 1 from the damaged part, the bag 2a covers the entire area of the submerged compartment 1 as in the embodiment shown in FIGS. It is possible to prevent the infiltration of water into the compartment 1 by closing the damaged portion by expanding the partition.

Next, FIG. 5 shows still another embodiment of the present invention. In the same structure as that shown in FIG. 4, the gas cylinder 3 is attached to the bag 2a arranged in each compartment 1.
Instead of individually connecting the gas supply pipes 4 to each other, a compressor 22 as a compressed gas supply unit is provided at a required position in the hull, and one end of the gas is connected to the compressor 22. The other end of the pipe 23 was branched so as to correspond to each section 1, and the tip end of each branch tube 23a was connected to the inlet of the bag 2a arranged in the center of the ceiling of each section 1. It is a thing.

Each of the branch pipes 23a of the gas supply pipe 23 is provided with a solenoid valve 5 which is opened by a switch 11 of the control panel 12a, like the solenoid valve 5 shown in FIG. When a relief valve 24 is provided on the tip side of the bag and the bag 2a connected to each branch pipe 23a is inflated by the compressed gas 7 supplied from the compressor 22 by opening the solenoid valve 5, In order to prevent the internal pressure of the bag body 2a from rising above a predetermined pressure set to be higher than the head pressure acting on the corresponding compartment 1 by a required amount, the excess amount of the compressed gas 7 to be supplied is increased by the relief valve 24. It is designed so that it can escape more.

Other configurations are similar to those shown in FIG. 4, and the same components are designated by the same reference numerals.

According to the present embodiment, the damaged portion of the hull outer plate I causes a flood in the corresponding compartment 1, or a fire occurs in the compartment 1 to cause a flooded compartment display portion of the control panel 12a. 9 and the warning lamp 10 on the fire occurrence section display 20
When or is lit, the switch 11 of the control panel 12a corresponding to the section 1 in which the occurrence of water or fire is displayed is connected to the bag 2a of the section 1 in which the water or fire has occurred. When the solenoid valve 5 of the branch pipe 23a is opened, the bag 2a can be inflated over the entire area of the compartment 1 by the compressed gas 7 supplied from the compressor 22, which is different from the embodiment shown in FIG. Similarly, it is possible to prevent water ingress and fire prevention in the compartments 1, and since it is sufficient to install one compressor 22 as a compressed gas supply unit for a large number of compartments 1, for each compartment 1 The entire structure can be simplified by eliminating the need to provide the gas cylinder 3.

The present invention is not limited to the above-mentioned embodiments, and in each of the above-mentioned embodiments, the case where the device of the present invention is applied to three sections 1 arranged in the lateral direction is exemplified. However, the number of partitions 1 to be applied may be increased or decreased and can be freely set from a single number to a large number,
In addition, the arrangement can be applied to the compartments 1 arranged in the vertical direction or the horizontal and vertical directions. If the structure is a floating structure having a hollow compartment 1 surrounded by an outer wall other than the ship, the compartment 1 That can be applied to the bags 2, 2a in the compartment 1
The installation position of may be a position other than the vicinity of the center of the ceiling part as long as it is a position where it is easy to inflate the bag body 2 and 2a in the entire area of the compartment 1 and does not interfere with it. If it is possible to promptly detect the inundation generated in the compartment 1 and issue the inundation detection signal, it is possible to adopt a configuration other than that shown in FIG. 3, and the control panel in the embodiment of FIGS. 1 to 3. 12 and the submerged section display part 9 of the control panel 12a in the embodiment of FIG. 4 and the embodiment of FIG. 5 are displayed as long as they are displayed so that the submerged section 1 can be easily identified. Water flood warning lamp 10
It is possible to employ any display means other than the above, and the fire occurrence section display unit 20 of the control panel 12a in the embodiment of FIG. 4 and the embodiment of FIG. 5 can easily identify the section where the fire is occurring. Any display means other than the fire warning lamp 21 may be adopted as the display means so long as it is displayed as described above. In the embodiment of FIGS. Instead of connecting the gas cylinders 3 individually, the compressor 22 may be connected via the gas supply pipe 23 having the branch pipe 23a as in the case shown in FIG. 4, and the bags 2 and 2a. An on-off valve that manually opens and closes the solenoid valve 5 is provided in the gas supply pipe 4 or the branch pipe 23a of the gas supply pipe connected to the on-off valve to manually operate the inundation of the compartment 1 and the occurrence of a fire. Open the bag by 2 and 2 May be so as to inflate the,
In this case, the gas supply pipe 4 and the branch pipe 23a of the gas supply pipe connected to the bags 2 and 2a arranged in a certain compartment 1 are once drawn to the adjacent compartment or the neighboring compartment, and the adjacent compartment or the neighboring compartment. It suffices to install an on-off valve on the gas supply pipe 4 and the branch pipe 23a located inside the fire detector 1 in each section 1 in the embodiment of FIG. 4 and the embodiment of FIG.
9 and a water infiltration sensor 8 are provided to prevent the fire from being extinguished and prevented by inflating the bag 2a made of a refractory material over the entire area of the compartment 1 when a fire or flood occurs in the compartment 1. I have shown that it can handle both,
Of course, the bag 2a made of refractory material may be used only for the purpose of extinguishing fire. In this case, only the fire detector 19 may be installed in each target section 1.
It is needless to say that the control panel 12a may be provided with only the fire occurrence section display section 20 and the switch 11, and various changes may be made within the scope not departing from the gist of the present invention.
