Technical Field
[0001] The present application relates to the field of ship security technology, and in particular to a ship-based fire-fighting and explosion-suppression device. Background Art
[0002] Ships refer to commercial vehicles that are mainly used for buoyancy support in water or marine environments and can transport or carry goods or passengers. Ships are mainly composed of hulls, ship power units, ship habitats and other equipment. The hull is mainly used to accommodate goods, machinery and personnel, and provide buoyancy and stability; the ship power unit provides power for the operation of the ship; ship habitats and other equipment include navigation equipment, cargo loading and unloading equipment, lighting equipment, fire-fighting equipment, etc.
[0003] During the voyage of a ship, a large amount of combustible materials (such as fuel) must be loaded in the hull. Therefore, electrical fires, fuel fires, explosions and other safety accidents often occur on the ship. Once an accident occurs, it will bring safety hazards to the cargo carried on the ship and the crew. Firefighting equipment, as an important ship habitat, plays a significant role in dealing with such hazards. However, in the prior art, most firefighting equipment is fire hydrants or fire extinguishers, which need to be operated by the crew after the accident to extinguish the fire. The timeliness is poor, and if the accident is discovered too late, such firefighting equipment is also difficult to suppress the fire. When the fire expands, it is very easy to cause more dangerous hazards such as explosions. Therefore, there is an urgent need for a ship-based fire-fighting and explosion-suppression equipment to improve the safety of the ship during navigation. Utility Model Content

DETAILED DESCRIPTION
[0028] The following is combined with Figure 1-2 This application is described in further detail.
[0029] The present application embodiment discloses a marine fire extinguishing and explosion suppression device. Figure 1 and Figure 2 , including a fire extinguishing nozzle 2 arranged on the top wall of the hull 1. In this embodiment, the fire extinguishing nozzle 2 adopts a shower head type nozzle to increase the fire extinguishing range, thereby improving the fire extinguishing effect; a fire fighting chamber 11 is opened in the top wall of the hull 1, and the fire extinguishing nozzle 2 is connected to the fire fighting chamber 11. The top wall of the fire fighting chamber 11 is connected with a rotating member 6 through a flange. The rotating member 6 adopts a motor, and its output shaft is arranged in the vertical direction. The output shaft of the rotating member 6 is connected with a wheel disc 7 by welding. The wheel disc 7 is penetrated with a plurality of sliding holes 71 along the thickness direction. The plurality of sliding holes 71 are evenly distributed along the circumferential direction of the wheel disc 7, and the fire extinguishing nozzle 2 is located on the rotation track of the sliding holes 71.
[0030] Reference Figure 1 and Figure 2 , each sliding hole 71 is slidably connected with a fire extinguishing tank 3, and dry powder is loaded in the fire extinguishing tank 3. The peripheral wall of one end of the fire extinguishing tank 3 above the wheel disc 7 is provided with an abutment plate 36 by welding. The diameter of the abutment plate 36 is larger than the diameter of the sliding hole 71, so as to limit the fire extinguishing tank 3 from leaving the wheel disc 7. A limiting rod 361 is vertically provided on the bottom wall of the abutment plate 36 by welding. A limiting hole 73 for the limiting rod 361 to pass through is opened in the thickness direction of the wheel disc 7 to prevent the fire extinguishing tank 3 from deflecting; a reset member 72 is provided between the abutment plate 36 and the surface of the wheel disc 7. In this embodiment, the reset member 72 adopts a spring, and the reset member 72 is sleeved on the peripheral wall of the fire extinguishing tank 3, and the reset member 72 abuts between the abutment plate 36 and the surface of the wheel disc 7. Under the action of the reset member 72, the fire extinguishing tank 3 always maintains a movement tendency away from the fire extinguishing nozzle 2.
[0031] Reference Figure 1 and Figure 2 The fire extinguishing nozzle 2 is located at one end of the fire fighting cavity 11 and is provided with an access groove 21 for the fire extinguishing tank 3 above to be inserted into. An access pipe 22 is vertically arranged at the center of the access groove 21 by welding. A plurality of access ports 221 are penetrated through the side wall of the access pipe 22. The plurality of access ports 221 are evenly distributed along the circumferential direction of the access pipe 22. The access pipe 22 is connected with the inside of the fire extinguishing nozzle 2; a connecting pipe 31 is vertically arranged in the fire extinguishing tank 3 by welding, and the open end of the connecting pipe 31 passes through the bottom wall of the fire extinguishing tank 3. In this embodiment, the inner wall diameter of the connecting pipe 31 is consistent with the outer wall diameter of the access pipe 22, and the access pipe 22 can be inserted into the connecting pipe 31.

At this time, the dry powder in the fire extinguishing tank 3 can enter the inner cavity of the fire extinguishing nozzle 2.
[0032] Reference Figure 1 and Figure 2The end of the sealing plunger 32 away from the elastic member 33 is connected to a sealing pad 34 by gluing. The sealing pad 34 extends out of the connecting pipe 31 and unfolds to abut against the bottom wall of the fire extinguishing tank 3 to improve the sealing performance. When abutted by the access pipe 22, the sealing pad 34 will fold and enter the connecting pipe 31; a guide surface 35 is provided in the fire extinguishing tank 3 along the circumferential direction, and the guide surface 35 is inclined toward the direction of the connecting port 311, so that the dry powder in the fire extinguishing tank 3 can continue to flow toward the connecting port 311; an air compressor 8 is provided in the inner cavity of the fire extinguishing nozzle 2 for compressing the air and then spraying it out at a high speed. The outlet of the air compressor 8 is arranged toward the outlet direction of the fire extinguishing nozzle 2 to increase the flow rate of the dry powder.

In this embodiment, the driving mechanism 4 adopts a cylinder; an alarm device 5 is connected to the top wall of the hull 1 by bolts, and the alarm device 5 is electrically connected to the driving mechanism 4. The alarm device 5 is used to monitor the fire. When the fire is detected, the driving mechanism 4 is started, so that the fire extinguishing tank 3 and the fire extinguishing nozzle 2 are abutted and connected, and dry powder is sprayed to extinguish the fire. The alarm device 5 can adopt a smoke alarm.
[0034] The implementation principle of a ship-based fire-fighting and explosion-suppression equipment in an embodiment of the present application is as follows: when the alarm device 5 detects that there is a fire in the hull 1, the drive mechanism 4 will be controlled to start, and the drive mechanism 4 will drive the start-up fire extinguishing tank 3 to move toward the direction of the fire-fighting nozzle 2, the fire-fighting tank 3 is docked with the fire-fighting nozzle 2, the access pipe 22 is inserted into the connection pipe 31, the sealing plunger 32 moves, the elastic member 33 is compressed, the access port 221 and the connection port 311 are connected, and the dry powder in the fire-fighting tank 3 will enter the inner cavity of the fire-fighting nozzle 2, and the dry powder will be diffused through the air flow blown out by the air compressor 8, thereby achieving the effect of fire-fighting and explosion-suppression, and improving the safety of the ship during navigation.
