[0026] In this embodiment, when a new energy electric vehicle catches fire, the device can be pushed by the universal wheel 7, and multiple devices are placed around the new energy electric vehicle to form a surrounding or semi-surrounding arrangement. The fire wall plate 3 is used to block the spread of fire and isolate heat radiation. The fire hose is connected to the water supply pipe 5, and high-pressure water flow is input into the net-shaped pipeline 4 through the water supply pipe 5. The net-shaped pipeline 4 is a multi-path water pipeline, and the high-pressure water flow is distributed to each fixed spray head 6 through the net-shaped pipeline 4. A large area and continuous water curtain is formed on the new energy electric vehicle to quickly extinguish the fire. At the same time, when the high-pressure water flow flows through each part of the net-shaped pipeline 4, the high-pressure water flow will take away the heat of the fire wall plate 3, continuously cool the fire wall plate 3, improve the fire resistance of the fire wall plate 3, and achieve the purpose of stable blocking of fire, thereby protecting nearby vehicles and pedestrians.

[0027] It should be noted that the bracket 2 is welded to the water storage tank 1, the net-shaped pipeline 4 is welded to the bracket 2, and the fire wall plate 3 is covered on the front side of the bracket 2 under the support of the net-shaped pipeline 4. The bracket 2, the net-shaped pipeline 4, and the fire wall plate 3 are connected to each other to form a stable structure. The water storage tank 1 is used to store water, which can lower the center of gravity of the device, so that the device can be in a stable upright state during the fire prevention and extinguishing process and the moving process, and is not easy to fall over. At the same time, the water in the water storage tank 1 can also absorb the heat of the fire wall plate 3 to ensure the fire blocking and heat insulating effect of the fire wall plate 3.

[0028] The net-shaped pipeline 4 is provided with multiple vertical pipes 4a parallel to each other, the top ends of the multiple vertical pipes 4a are connected to each other through the return pipe 4b, the bottom ends of the multiple vertical pipes 4a are connected to the upper side of the water supply pipe 5, the two ends of the water supply pipe 5 are located outside the fire wall plate 3, and the multiple fixed spray heads 6 are connected to the side surfaces of the vertical pipes 4a and the return pipe 4b.

In addition, the high-pressure water flow is continuously input from the two ends of the water supply pipe 5, so as to ensure that enough water is delivered to each part of the net-shaped pipeline 4, thereby ensuring the continuous generation of a large area of water curtain and enhancing the fire extinguishing performance of the device.

[0029] The water supply pipe 5 is horizontally attached to the inner bottom surface of the water storage tank 1, the side surface of the water supply pipe 5 is provided with two branch pipes 8 in communication with the inside thereof, the ends of the branch pipes 8 away from the water supply pipe 5 penetrate through the bottom of the water storage tank 1, and are connected with a transverse pipe 10 through a rotary joint 9, the end of the transverse pipe 10 away from the rotary joint 9 is provided with a rotary spray head one 11, and the side surface of the transverse pipe 10 is provided with at least one rotary spray head two 12, and the nozzles of the rotary spray head one 11 and the rotary spray head two 12 are vertically upwardly arranged.

[0030] When the water supply pipe 5 is connected with high-pressure water flow, the high-pressure water flow is branched to the rotary spray head one 11 and the rotary spray head two 12 through the branch pipes 8, the rotary joint 9 and the transverse pipe 10, and the rotary spray head one 11 and the rotary spray head two 12 form a rotary spray water curtain to spray water on the bottom of the new energy electric vehicle in a large area, mainly for cooling control and fire extinguishing treatment of the charging battery, to prevent the charging battery from causing high-temperature deflagration due to excessive burning, and to avoid further expansion of the fire;

[0031] It should be understood that the rotary joint 9 can make the transverse pipe 10 repeatedly swing horizontally, and when the bottom of the electric vehicle needs to be sprayed, the transverse pipe 10 can be pushed from below the water storage tank 1 to swing to the bottom of the vehicle, so that the transverse pipe 10 can be quickly moved to the bottom of the electric vehicle without being hindered by the tires and repeatedly adjusting the position of the device;

[0032] It should be understood that the water supply pipe 5 is fixed to the bottom of the water storage tank 1 through the branch pipe 8, so as to increase the stability and safety of the support 2 and the fireproof wall plate 3.

[0033] It also includes a gas spring telescopic rod 13 and a spring latch 14, one end of the gas spring telescopic rod 13 is hinged to the bottom of the water storage tank 1, the other end of the gas spring telescopic rod 13 is hinged to the side surface of the transverse pipe 10, the spring latch 14 is vertically arranged on the front side surface of the water storage tank 1, the top end of the spring latch 14 is provided with a horizontal pull rod 15, the length of the horizontal pull rod 15 is greater than the length of the water storage tank 1, and the bottom end of the spring latch 14 is lower than the height of the bottom surface of the water storage tank 1.

[0034] The two ends of the water supply pipe 5 penetrate through the two sides of the water storage tank 1 and extend to the outside of the water storage tank 1. The water supply pipe 5 is fixed via the two sides of the water storage tank 1, thereby further increasing the stability and safety of the support 2 and the fireproof wall plate 3, and improving the stability and convenience when connecting the high-pressure water flow.

[0035] The fireproof wall plate 3 comprises a plurality of wall plate units 3a arranged side by side, and the material of the fireproof wall plate 3 is one or more of aluminum silicate fiber, diatomite, refractory brick, and asbestos. Dividing the fireproof wall plate 3 into a plurality of wall plate units 3a, the weight of a single wall plate unit 3a is lighter, and the pressure applied to the mesh pipe 4 is also relatively small, thereby prolonging the service life of the mesh pipe 4.

[0036] The impact-resistant baffle 16 is arranged in the water storage tank 1 and located at the rear side of the support 2. The impact-resistant baffle 16 is welded on the water storage tank 1 and adheres to the rear side of the support 2. The purpose of installing the impact-resistant baffle 16 is to strengthen the impact resistance of the structure. When the new energy electric vehicle burns and explodes, even if the fireproof wall plate 3 is penetrated, the impact-resistant baffle 16 can still protect the surrounding vehicles and personnel, and also plays a balancing and stabilizing role for the support 2 and the fireproof wall plate 3.
