[0002] The most common cause of electric vehicle fires is the fire igniting of the electric vehicle battery. The current common solution is to continuously cool the vehicle with a large amount of water. For example, Chinese Patent Publication No. CN117731983A, the patent titled "New Energy Vehicle Fire Extinguishing Chamber", mainly includes "after the towing device drags the new energy vehicle into the fire extinguishing chamber body, the first spraying mechanism is used to spray fire extinguishing material towards the bottom of the new energy vehicle".

[0003] However, once an electric vehicle battery catches fire, it burns rapidly and reaches extremely high temperatures, making it difficult to approach. Furthermore, the battery pack carries the risk of secondary explosion. The corresponding towing device's rope is typically made of steel wire rope and metal hooks, which are quite heavy. Under these circumstances, it is difficult to quickly and effectively connect the towing device to the violently burning vehicle. To solve this problem, we propose a new technical solution.

[0030] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0031] Please refer to Figure 1 Figure 10 The immersion movable new energy vehicle fire extinguishing module provided by the embodiment of the present application comprises a loading warehouse 1, a booster water tank 2 and a winch unit 3 are installed at the first end of the loading warehouse 1, a base cylinder 4 in communication with the booster water tank 2 is movably installed at the inner bottom of the loading warehouse 1, a water spray arm cylinder 5 is coaxially inserted and sleeved on the base cylinder 4, the water spray arm cylinder 5 can be driven by the water flow of the booster water tank 2 to pass from below the chassis of the burning vehicle, a hook rod 6 is movably installed on the extending end of the water spray arm cylinder 5, the rod body of the hook rod 6 is connected with the cable of the winch unit 3, and when the winch unit 3 is wound, the hook rod 6 and the water spray arm cylinder 5 form a hook claw state capable of hooking and pulling the burning vehicle;

[0032] ​Specifically, the loading bin 1 is a top-opened flat bin body, which can be transported by a drawbar hook transport vehicle. The loading and unloading principle between the drawbar hook transport vehicle and the loading bin 1 is a prior art and is not described herein. The loading bin 1 is entirely coated with an insulating paint layer. Preferably, the color of the insulating paint layer is red insulating paint, which is beneficial to improve the safety hazard of electric shock in fire extinguishing of the new energy vehicle. The number of the pressurized water pumps installed on the tank body of the pressurized water tank 2 corresponds to the number of the pressurized water pumps. The fire-fighting water stored in the tank body of the pressurized water tank 2 contains water-soluble magnesium hydroxide fire-retardant extinguishing agent. Preferably, the magnesium hydroxide fire-retardant extinguishing agent is S-46-AB type fire-retardant agent. The output pipeline of the fire-fighting water of the pressurized water tank 2 is provided with an on-off valve. Preferably, the on-off valve is a pneumatic control on-off valve, which includes a high-pressure gas cylinder, a pressure reducing valve and an electromagnetic valve, so as to realize pneumatic control of the on-off valve. The principle is a prior art and is not described herein. Preferably, the winch unit 3 includes a winch 3.1, which is installed on the loading bin 1 through a cross beam plate 3.2. The cable on the winch 3.1 is guided through a plurality of fixed pulleys and connected with the hook rod 6. The winch 3.1 can be selected as an electric winch or a hydraulic winch. The electric winch has a pulling force of more than 5 tons. The winch 3.1 is externally provided with corresponding protective heat insulation shielding plate members, which are prior arts and are not described herein.

[0033] The base cylinder 4 is located at the central position of the inner bottom of the loading bin 1. The cross-sectional outer profiles of the base cylinder 4 and the water jet arm cylinder 5 are preferably rectangular. The length direction line of the base cylinder 4 is parallel to the length direction line of the loading bin 1. The cylinder port direction of the base cylinder 4 is directed to the direction where the loading and unloading port of the loading bin 1 is located. The cylinder port of the water jet arm cylinder 5 is inserted into the base cylinder 4.

[0034] In actual use, for example, when the new energy vehicle is on fire, the loading bin 1 is transported to the fire extinguishing site by the drawbar hook transport vehicle. The drawbar hook transport vehicle places the loading bin 1 in the front area of the new energy vehicle on fire through the self-provided drawbar hook. Then the high-pressure water flow in the pressurized water tank 2 enters the base cylinder 4. The water jet arm cylinder 5 is stretched out towards the outside of the base cylinder 4 under the push of the high-pressure water flow. The water jet arm cylinder 5 is further stretched out from the loading bin 1. At the same time, the winch unit 3 is reversely rotated to release the cable. The cylinder bottom end of the water jet arm cylinder 5 drives the hook rod 6 to completely pass under the chassis of the burning vehicle until the water jet arm cylinder 5 reaches the maximum stretching length. At this time, the winch unit 3 also reaches the maximum cable release length. During the stretching process of the water jet arm cylinder 5, the distance value between the highest point position of the hook rod 6 and the ground is much smaller than the distance value between the chassis of the burning vehicle and the ground. At this time, the hook rod 6 is in a state of avoidance.

[0035] When the winch unit 3 occurs the positive rotation of winding the cable, at this time the hook pull rod 6 is pulled by the cable of the winch unit 3, so that the hook pull rod 6 occurs the positive deflection, at this time the distance value between the highest point position of the hook pull rod 6 and the ground is much larger than the distance value between the burning vehicle chassis and the ground, the hook pull rod 6 and the water jet arm barrel 5 form the claw state capable of hooking the burning car, the hook pull rod 6 also reaches the maximum positive deflection position, with the winch unit 3 continues to rotate positively to wind the cable, at this time the hook pull rod 6 drives the water jet arm barrel 5 to retract towards the base barrel 4, at the same time, the hook pull rod 6 in the claw state also completes the hooking with the burning car, and then hooks the burning car into the loading chamber 1.

[0036] During the whole dragging process, no other auxiliary equipment needs to be additionally arranged, the structure is simple, the fire resistance is strong, the burning vehicle can be automatically hooked, the quick and effective dragging connection with the severely burning vehicle is effectively realized, time is saved, and the fire rescue work can be rapidly carried out.

[0037] Another embodiment provided by the present application is that the loading chamber 1 comprises a flatbed truck box 1.1, a tail plate 1.2 is hingedly installed at the tail end bottom of the flatbed truck box 1.1, and a pulling assembly 1.3 connected with the tail plate 1.2 is installed on each side of the truck box 1.1; when the burning vehicle moves in the flatbed truck box 1.1, the pulling assembly 1.3 drives the tail plate 1.2 to close at the end of the truck box 1.1.

[0038] The tail plate 1.2 has a blocking position and an inclined position on the flatbed truck box 1.1; the tail plate 1.2 can form a water storage space with the flatbed truck box 1.1 at the blocking position; the tail plate 1.2 and the flatbed truck box 1.1 are overlapped at a gap position and are provided with corresponding high-temperature-resistant sealing pads, so that the water storage space is ensured to be water-tight; and the tail plate 1.2 can form a slope surface at the loading and unloading opening of the tail end of the flatbed truck box 1.1 at the inclined position, which is beneficial to the transfer of the burning vehicle on the ground to the flatbed truck box 1.1; preferably, a plurality of rotating rollers 1.4 are installed on the surface of the tail plate 1.2, which is beneficial to further reducing the friction resistance of the vehicle passing through the inclined position of the tail plate 1.2.

[0039] In actual use, when the vehicle is located on the ground, the tail plate 1.2 is switched from the blocking position to the inclined position under the action of the pulling assembly 1.3; and when the vehicle is located in the flatbed truck box 1.1, the tail plate 1.2 is switched from the inclined position to the blocking position under the action of the pulling assembly 1.3.

[0040] In still another embodiment of the present application, the pulling assembly 1.3 comprises a sleeve 1.31 fixed to the top of the flatbed 1.1, the length direction of the sleeve 1.31 is parallel to the length direction of the flatbed 1.1, a toothed rod 1.32 is movably arranged in the sleeve 1.31, both ends of the toothed rod 1.32 extend out of the sleeve opening of the sleeve 1.31, one end of the toothed rod 1.32 is connected to the tail plate 1.2 through a pulling rope 1.33, the other end of the toothed rod 1.32 is provided with a transmission assembly 7 in transmission connection with the winch unit 3, the transmission assembly 7 comprises an extension rod 7.1 coaxially fixed to the winding shaft of the winch unit 3, a gear 7.2 capable of one-way meshing transmission with the toothed rod 1.32 is fixed to the extension rod 7.1;

[0041] Further, the loading bin 1 is provided with a spray pipe unit 8, the spray pipe unit 8 comprises a pipe support 8.1 fixed to the corresponding toothed rod 1.32 at both ends, the pipe support 8.1 is located on the stroke of the moving vehicle in the flatbed 1.1, a conveying pipe 8.2 in communication with the booster water tank 2 is mounted on the pipe support 8.1, the conveying pipe 8.2 can be selected as a steel wire hose, a dispersion pipe 8.3 in communication with the conveying pipe 8.2 is fixed to the pipe support 8.1;

[0042] In actual use, for example, the vehicle is completely in the flatbed 1.1, at this time, the vehicle moves in the flatbed 1.1, at this time, the advancing end of the vehicle pushes the pipe support 8.1, so that the pipe support 8.1 moves horizontally in the length direction of the flatbed 1.1, since the pipe support 8.1 is fixed to the toothed rod 1.32, at this time, one end of the toothed rod 1.32 pulls the tail plate 1.2 through the pulling rope 1.33, so that the tail plate 1.2 is deflected from the slope position to the blocking position, when the tail plate 1.2 reaches the blocking position, at this time, the winch unit 3 also reaches the maximum cable winding position, stops winding the cable, and the water spraying arm cylinder 5 reaches the maximum retraction position;

[0043] It needs to be specially pointed out that, in the process of the pipe support 8.1 moving horizontally in the positive direction, the other end of the toothed rod 1.32 also moves in the positive direction towards the gear 7.2, so that the toothed rod 1.32 is meshed with the gear 7.2, in this process, since the gear 7.2 also rotates in the positive direction synchronously with the winch unit 3, the gear 7.2 and the toothed rod 1.32 do not have meshing transmission force, when the winch unit 3 reaches the maximum cable winding position, at this time, the toothed rod 1.32 is in meshing state with the gear 7.2;

[0044] When the tail plate 1.2 reaches the blocking position, the booster water pump in the booster water tank 2 at this time transmits the fire-fighting water to the dispersion pipe 8.3 through the conveying pipe 8.2, and then the fire-fighting water is sprayed on the vehicle to cool and extinguish the fire by the dispersion pipe 8.3, and the water flow also gathers in the water loading space of the flat car box 1.1, so that the rising fire-fighting water can soak the vehicle battery pack to isolate air and cool it down, in addition, a plurality of water spraying pipes connected with the booster water tank 2 are also fixed on the inner wall side of the flat car box 1.1, and the water spraying pipes are provided with water spraying holes on the pipe body facing the side of the vehicle, so as to cooperate with the dispersion pipe 8.3 to extinguish the fire and cool the vehicle;

[0045] When the fire extinguishing is finished and the vehicle needs to be removed from the flat car box 1.1, the winch unit 3 is reversely rotated at this time, so that the gear 7.2 also synchronously reversely rotates with the reverse rotation of the winch unit 3, at this time, the gear 7.2 and the toothed rod 1.32 generate meshing transmission force, the toothed rod 1.32 is reversely moved by receiving the meshing drive of the gear 7.2, so that the tail plate 1.2 is no longer pulled by the traction rope 1.33, and the tail plate 1.2 at the blocking position is pushed and switched to the slope position by the reverse movement of the toothed rod 1.32;

[0046] At the same time when the toothed rod 1.32 reversely moves, the pipe frame 8.1 also reversely horizontally moves by receiving the drive of the toothed rod 1.32, so as to generate a pushing force for the vehicle to separate from the flat car box 1.1, which is beneficial to the removal of the vehicle from the flat car box 1.1, when the gear 7.2 and the toothed rod 1.32 are separated, the pipe frame 8.1 also reaches the maximum position of the reverse horizontal movement.

[0047] In another embodiment of the application, the end side of the base cylinder 4 is fixed with a shaft cylinder 9, the axis of the shaft cylinder 9 is perpendicular to the axis of the base cylinder 4, the axis of the shaft cylinder 9 is parallel to the horizontal plane, the cylinder end of the shaft cylinder 9 is rotatably inserted with a flow guide pipe 10 connected with the booster water tank 2, the flow guide pipe 10 is a hard pipe body fixed with the loading bin 1, and the both ends of the shaft cylinder 9 protruding from the cylinder body of the base cylinder 4 are rotatably installed with support ear plates 11 fixed with the loading bin 1.

[0048] Further, the shaft cylinder 9 is sequentially provided with a first cylinder opening 12 and a second cylinder opening 13 on the circumferential surface of the cylinder body in the base cylinder 4, and the pipe body of the flow guide pipe 10 is provided with a pipe side opening 14 in the pipe body in the shaft cylinder 9, so that when any one of the first cylinder opening 12 and the second cylinder opening 13 overlaps with the pipe side opening 14, the booster water tank 2 and the base cylinder 4 are in a conductive state.

[0049] The base cylinder 4 can be deflected with the shaft cylinder 9 as the center, and the deflection of the base cylinder 4 forms a sector-shaped estimation surface perpendicular to the horizontal plane. The base cylinder 4 has a horizontal position, a first elevation angle position, and a second elevation angle position within its deflection range. The included angle of the first elevation angle position is smaller than that of the second elevation angle position.

[0050] When the base cylinder 4 is in the horizontal position, the axis of the base cylinder 4 is parallel to the horizontal plane, and the first cylinder opening 12 overlaps the pipe side opening 14, so that the water flow in the booster water tank 2 is boosted by the booster pump and then discharged by the flow guide pipe 10. The water flow in the flow guide pipe 10 enters the base cylinder 4 through the first cylinder opening 12 and the pipe side opening 14, thereby providing driving force for the water spray arm cylinder 5 to extend outwardly from the base cylinder 4.

[0051] When the base cylinder 4 is in the first elevation angle position, the pipe side opening 14 is blocked by the cylinder wall of the shaft cylinder 9, and the first cylinder opening 12 and the second cylinder opening 13 are also blocked by the pipe wall of the flow guide pipe 10. The first cylinder opening 12, the second cylinder opening 13, and the pipe side opening 14 are staggered with each other. At this time, the water flow in the booster water tank 2 cannot enter the base cylinder 4, and the base cylinder 4 and the flow guide pipe 10 are in a blocked state.

[0052] When the base cylinder 4 is in the second elevation angle position, the second cylinder opening 13 overlaps the pipe side opening 14, so that the water flow in the booster water tank 2 is boosted by the booster pump and then discharged by the flow guide pipe 10. The water flow in the flow guide pipe 10 enters the base cylinder 4 through the second cylinder opening 13 and the pipe side opening 14.

[0053] In actual use, when the hook pull rod 6 is converted from the avoidance state to the hook claw state, the included angle between the axis of the hook pull rod 6 and the horizontal plane increases. Under the support of the rod body of the hook pull rod 6, the base cylinder 4 is switched from the horizontal position to the first elevation angle position, and the base cylinder 4 is deflected upward, thereby facilitating the further approach of the hook pull rod 6 to the vehicle for hooking and improving the stability of the hooking and pulling process. When the hook pull rod 6 in the hook claw state enters the loading compartment 1 from the ground, the inner bottom surface of the loading compartment 1 is higher than the horizontal ground. Under the support of the rod body of the hook pull rod 6, the base cylinder 4 is switched from the first elevation angle position to the second elevation angle position. The base cylinder 4 is deflected upward again, which is beneficial to increase the gap between the bottom of the vehicle and the inner bottom of the loading compartment 1, increase the space for containing the fire-fighting liquid between the vehicle and the loading compartment 1, thereby improving the cooling and heat conduction effect and solving the problem of insufficient thickness of the cooling layer formed by the fire-fighting liquid due to the close distance between the battery pack and the bottom of the loading compartment 1.

[0054] In still another embodiment of the present application, the nozzle of the water spraying arm cylinder 5 is inserted into the base cylinder 4, the top of the water spraying arm cylinder 5 is provided with a plurality of spray holes 15, an inner liner cylinder 16 is fitted and installed in the water spraying arm cylinder 5, the outer wall surface of the inner liner cylinder 16 is adapted to the inner wall surface of the water spraying arm cylinder 5, the nozzle of the inner liner cylinder 16 is consistent with the nozzle of the water spraying arm cylinder 5, the inner liner cylinder 16 is provided with a notch 17 that can be aligned with the spray hole 15, when the spray hole 15 is aligned with the notch 17, the water flow in the water spraying arm cylinder 5 is sprayed towards the bottom of the vehicle through the overlapping opening formed by the spray hole 15 and the notch 17, thereby achieving the effect of fire extinguishing and cooling, the bottom end of the water spraying arm cylinder 5 is movably connected with a convex support column 18 fixed to the inner liner cylinder 16;

[0055] Further, the rod body side of the hook rod 6 is hinged to the bottom end of the water spraying arm cylinder 5 through a hinge seat 19, the hinge seat 19 is located above the convex support column 18, the bottom end of the hook rod 6 is movably connected with a support wheel 20, the support wheel 20 rolls to reduce friction when the hook rod 6 moves, the support wheel 20 is made of fireproof, flame-retardant and high-temperature-resistant material, for example, the support wheel 20 is a metal wheel, the bottom end side of the hook rod 6 in the hook claw state can generate a pushing force on the inner liner cylinder 16 through the convex support column 18, thereby forming an overlapping opening of the spray hole 15 and the notch 17;

[0056] In actual use, when the water spraying arm cylinder 5 moves outwardly towards the base cylinder 4, at this time the inner liner cylinder 16 is pushed by the water flow, thereby moving linearly in the water spraying arm cylinder 5, at this time the outer wall surface of the bottom end of the inner liner cylinder 16 is attached to the inner wall surface of the bottom end of the water spraying arm cylinder 5, the convex support column 18 is in a protruding state, the spray hole 15 is misaligned with the notch 17, the cylinder body of the inner liner cylinder 16 is in a blocking state to the spray hole 15, thereby ensuring that the water flow remains in the water spraying arm cylinder 5 during the outward movement of the water spraying arm cylinder 5 towards the base cylinder 4, so that the water spraying arm cylinder 5 can fully receive the water flow driving;

[0057] When the winch unit 3 rotates in the forward direction to wind the cable, the hook rod 6 changes from the avoiding state to the hook claw state, at this time the hook rod 6 in the hook claw state is pulled by the cable of the winch unit 3, thereby generating a pushing force on the convex support column 18 when the hook rod 6 is deflected to the hook claw state, thereby moving the convex support column 18 towards the water spraying arm cylinder 5, further driving the inner liner cylinder 16 to move synchronously in the water spraying arm cylinder 5, so that the overlapping opening of the spray hole 15 and the notch 17 is formed, at this time the fire-fighting water in the water spraying arm cylinder 5 can be sprayed outwardly;

[0058] Further, when the hooking rod 6 is in the hooking state, the base cylinder 4 is in the first elevation angle position, the fire-fighting water in the booster water tank 2 stops entering the base cylinder 4, at this time, the water spraying arm cylinder 5 is retracted towards the base cylinder 4, so that the fire-fighting water in the base cylinder 4 and the water spraying arm cylinder 5 is extruded, and is sprayed outwards through the overlapping opening formed by the injection hole 15 and the gap 17, so as to extinguish and cool the bottom of the vehicle, and at the same time, the heat dissipation of the water spraying arm cylinder 5 and the hooking rod 6 is accelerated. With the forward rotation of the winch unit 3 to wind the cable, when the base cylinder 4 is in the second elevation angle position, the fire-fighting water in the booster water tank 2 resumes to enter the base cylinder 4, and is sprayed outwards through the overlapping opening formed by the injection hole 15 and the gap 17, so as to continuously spray and cool the bottom of the vehicle.

[0059] In other words, the hooking rod 6 is installed on the water spraying arm cylinder 5 which can be extended and retracted through the bottom of the vehicle, the hooking rod 6 can be automatically hooked and dragged into the loading cabin 1 when the water spraying arm cylinder 5 is retracted, and the extension and retraction of the water spraying arm cylinder 5 can be cooperated with the opening and closing of the tail plate 1.2 at the loading and unloading end of the loading cabin 1, and at the same time, the temperature in the area close to the vehicle can be reduced during the hooking and dragging process, and the pre-fire-fighting effect is achieved, the overall structure is simple, and the operation is convenient.

[0060] The above describes some exemplary embodiments of the present application by way of illustration only, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
