Abstract
Description
Technical Field
[0001] The present application relates to the field of fire extinguishing under a roll-on / roll-off ship, and in particular to a fire extinguishing foam device for the chassis of a marine electric vehicle. Background Art
[0002] With the rapid economic development, electric vehicles have been widely used. In the transportation of passenger and vehicle ro-ro ships, the transportation of electric vehicles has become very convenient. Because electric vehicles are different from other fuel vehicles, the batteries of electric vehicles are all at the bottom of the vehicle and are very dense. During transportation, it is not possible to completely guarantee that there will be no contact and other unexpected situations. The batteries of electric vehicles may sometimes have safety problems such as "explosion" and "spontaneous combustion".
[0003] With respect to the above-mentioned related technologies, the inventor believes that the traditional method of ship fire extinguishing is to extinguish the fire by directly spraying water with a high-pressure water gun. However, since the battery module of an electric vehicle is under the vehicle, the traditional method of using water to extinguish the battery fire cannot effectively cause excessive losses. Summary of the invention
[0004] In order to solve the problem that the traditional marine fire extinguishing method cannot effectively extinguish the fire when the bottom of the electric vehicle catches fire, the present application provides a marine electric vehicle chassis fire extinguishing foam device.
[0005] The present application provides a marine electric vehicle chassis fire extinguishing foam device that adopts the following technical solution:
[0006] A fire extinguishing foam device for a chassis of a marine electric vehicle comprises a water tank, a plurality of nozzles are fixedly connected to the water tank, a first water inlet pipe is fixedly connected to one side of the water tank, and a moving component for driving the water tank to move is arranged at the bottom end of the water tank.
[0007] Optionally, the water tank includes a water inlet portion connected to the first water inlet pipe.
[0008] A covering portion is provided on a side of the water inlet portion away from the first water inlet pipe, the covering portion is relatively connected to the water inlet portion, and an effective area of the covering portion is larger than an effective area of the water inlet portion.
[0009] Optionally, the nozzle is an atomizing nozzle, and the spraying direction of the nozzle is upward.
[0010] Optionally, the first water inlet pipe is connected to a first joint at one end away from the water tank, and the first joint is connected to a fire-fighting water pipe.
[0011] Optionally, the first connector is a quick-release connector.
[0012] Optionally, a second water inlet pipe is fixedly connected to one side of the first water inlet pipe, a second joint is provided at one end of the second water inlet pipe away from the first water inlet pipe, and the second water inlet pipe is relatively connected to the foam device.
[0013] Optionally, a switch valve is provided on the second water inlet pipe, and the switch valve controls the medium in the second water inlet pipe to enter the water tank.
[0014] Optionally, the moving assembly includes a plurality of universal wheels located at the bottom end of the sink.
[0015] Optionally, the first water inlet pipe is connected to the water tank at an angle, and the first water inlet pipe gradually inclines downward from an end away from the water tank to an end close to the water tank.
[0016] Optionally, a handle is provided on the first water inlet pipe, and the handle is fixedly connected to the first water inlet pipe.
[0017] In summary, the present application includes at least one of the following beneficial technical effects:
[0018] 1. The nozzle can atomize the water to form a water wall. The water inlet pipe is connected to the water tank at an angle, so that the liquid inside the first water inlet pipe can be quickly injected into the inside of the water tank.

When water enters the first water inlet pipe, the flow rate inside the first water inlet pipe is greater than the flow rate of the second water inlet pipe near one end of the first water inlet pipe, so that the pressure at the position of the first water inlet pipe near the second water inlet pipe is lower than the pressure at the position of the second water inlet pipe near the first water inlet pipe, and the foam in the second water inlet pipe is sucked into the first water inlet pipe and enters the sink.

The coverage area of the fire extinguishing medium sprayed from the covering part 12 is larger than the coverage area of the fire extinguishing medium sprayed from the water inlet 11.
[0030] In some embodiments, the water tank 1 is an annular water tank 1, and the water inlet 11 and the covering part 12 surround a closed rectangular space. In other embodiments, multiple covering parts 12 are provided, and the water inlet 11 is relatively connected to multiple covering parts 12, and the multiple covering parts 12 are all located below the bottom plate.
[0031] The water inlet portion 11 is provided with a plurality of nozzles 2 on both sides along the horizontal direction, and the plurality of nozzles 2 on both sides are arranged in a staggered manner. The covering portion 12 is provided with a plurality of nozzles 2 on both sides along the horizontal direction, and the plurality of nozzles 2 on both sides are arranged in a staggered manner. The nozzle 2 is relatively fixedly connected to the water tank 1. When water enters the water tank 1, the water in the water tank 1 will be sprayed out through the nozzle 2. The nozzle 2 is an atomizing nozzle 2, and the spraying direction of all the nozzles 2 is upward. The nozzle 2 can atomize the water to form a water wall.
[0032] A driving assembly for driving the water tank 1 to move is provided at the bottom end of the water tank 1. In some embodiments, the driving assembly is a universal wheel 3 installed at the four corners of the water tank 1. The universal wheel 3 can move forward and backward in 360 degrees, so that the water tank 1 can be better moved to the bottom of the electric car.
[0033] The first water inlet pipe 4 is connected to one end away from the water tank 1 with a first joint 41, which is fixedly connected to the first water inlet pipe 4 and connected to an external fire hose. The first joint 41 is a quick-release joint, which facilitates quick disassembly of the first water inlet pipe 4 from the external fire hose.
[0034] The first water inlet pipe 4 is connected to the water tank 1 at an angle, and the first water inlet pipe 4 gradually inclines downward from the end away from the water tank 1 to the end close to the water tank 1. The inclined first water inlet pipe 4 facilitates the rapid injection of liquid inside the first water inlet pipe 4 into the water tank 1.
[0035] A handle 5 is provided on the first water inlet pipe 4, and the handle 5 is provided at the lower part of the first water inlet pipe 4 and is fixedly connected to the first water inlet pipe 4.

[0038] When the switch valve is opened, foam enters the second water inlet pipe 6. When water enters the first water inlet pipe 4, the flow rate inside the first water inlet pipe 4 is greater than the flow rate at the end of the second water inlet pipe 6 near one end of the first water inlet pipe 4, so that the pressure at the position of the first water inlet pipe 4 near the second water inlet pipe 6 is less than the pressure at the position of the second water inlet pipe 6 near the first water inlet pipe 4, and the foam in the second water inlet pipe 6 is sucked into the first water inlet pipe 4 and enters the water tank 1, and the nozzle 2 sprays the foam in the water tank 1. When the switch valve is closed, the foam will be stored in the second water inlet pipe 6, so that the foam will not be sprayed out from the inside of the nozzle 2.
[0039] When working, the handle 5 is pushed to drive the four universal wheels 3 to push the water tank 1 to the bottom of the electric car, and then the fire hose on the fire hydrant on the ship is connected to the first joint 41, and the water is allowed to flow into the water inlet part 11 and the covering part 12 of the water tank 1 through the first water inlet pipe 4 by water pressure, and the water is sprayed out through the nozzle 2 connected to the water inlet part 11 and the covering part 12 to form atomization and form a water wall. When foam is needed, the foam device is connected to the second joint 621 on the second water inlet pipe 6 to open the switch valve. The foam enters the water tank 1 and is sprayed out through the nozzle 2.
