[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] Example: Figure 1 , 2 As shown in Figures 3 and 4, the clearing and fire-fighting vehicle of this embodiment includes a clearing vehicle body 1 and a vehicle battery fire extinguishing system. A flatbed bracket 11 is hinged to the chassis of the clearing vehicle body 1. A first lifting cylinder 12 connected to the flatbed bracket 11 is mounted on the chassis. A trailer flatbed 13 is slidably mounted on the flatbed bracket 11. A push-pull cylinder 14 connected to and pushing the trailer flatbed 13 to slide is provided on the flatbed bracket 11. A vehicle towing device 2 is provided at one end of the flatbed bracket 11 or the trailer flatbed 13 near the front of the vehicle. The vehicle battery fire extinguishing system includes a dry powder tank 3 and a dry powder automatic spray fire extinguishing assembly. The dry powder automatic spray fire extinguishing assembly is mounted on the upper surface of the trailer flatbed 13 and is connected to the dry powder tank 3 through a pipeline. A booster 4 connected to the dry powder tank 3 is provided on the chassis.

[0027] In this embodiment, the clearing and fire truck adopts the existing clearing vehicle body structure and has the existing clearing vehicle towing function. Specifically, when the entire vehicle drives in front of the target rescue vehicle, the first lifting cylinder 12 extends to drive the flatbed support 11 and the trailer flatbed 13 to lift up (the front end of the vehicle is lifted upward). Next, the push-pull cylinder 14 drives the trailer flatbed 13 to slide relative to the flatbed support 11 towards the parking space, so that the rear end of the trailer flatbed 13 lands on the ground. Next, the vehicle towing device 2 is connected to the vehicle to be rescued, and then the vehicle to be rescued is towed forward onto the trailer flatbed 13. After that, the trailer flatbed 13 slides back into place, and the first lifting cylinder 12 retracts, so that the flatbed support 11, the trailer flatbed 13 and the vehicle on it fall smoothly on the chassis. When the battery at the bottom of the vehicle being rescued reignites, the dry powder in the dry powder canister 3 is transported to the automatic dry powder spraying fire extinguishing assembly through the booster 4. A large amount of dry powder is then sprayed onto the bottom of the vehicle through the automatic dry powder spraying fire extinguishing assembly on the trailer flatbed 13, thereby extinguishing the fire during the transfer process. The safety of the rescue is greatly improved, and the overall design is very much in line with the development of the modern automotive industry.

[0028] In this embodiment, two first lifting cylinders 12 are designed, distributed on the left and right sides of the vehicle.

[0029] In a preferred embodiment, the aforementioned dry powder automatic spray fire extinguishing assembly includes a dry powder nozzle 5 with a built-in solenoid valve. Multiple dry powder nozzles 5 are spaced apart and embedded in the upper end of the trailer flatbed 13. Each dry powder nozzle 5 is connected to a diversion chamber 51 through a pipeline. The diversion chamber 51 is connected to the dry powder tank 3 through a pipeline. The solenoid valve and the booster 4 are respectively connected to the control system of the vehicle body 1 of the clearing vehicle.

[0030] In the above implementation scheme, when fire needs to be extinguished during the transfer process, the control system controls the solenoid valve to open, the booster 4 pressurizes synchronously, and the dry powder in the dry powder tank 3 is quickly transported to the dry powder nozzle 5 and sprayed out, so as to quickly extinguish the reignition (combustion) of the battery at the bottom of the transfer vehicle.

[0031] In this embodiment, multiple dry powder nozzles 5 can be arranged in a row at intervals and installed in the middle area of ​​the trailer flatbed 13, or evenly distributed on the upper surface of the trailer flatbed 13.

[0032] In this embodiment, the control system is the original control system in the cab of the clearing vehicle body 1, which is existing technology and will not be described in detail here.

[0033] In a preferred embodiment, a smoke sensor 52 is embedded on the upper part of the trailer flatbed 13 near each of the dry powder nozzles 5, and the smoke sensor 52 is connected to the control system.

[0034] In the above implementation scheme, when the vehicle battery on the transport vehicle (i.e., the vehicle on the trailer flatbed 13) catches fire (reignites), it will produce a large amount of thick smoke, which will be detected by the smoke sensor 52. The detected signal will be sent to the control system, which will then control the solenoid valve in the dry powder nozzle 5 to open and simultaneously control the booster 4 to run, thereby quickly spraying dry powder to extinguish the fire as soon as possible. The response time is short and the fire extinguishing is very timely.

[0035] In this embodiment, it is best to set eight smoke sensors 52 and dry powder nozzles 5, arranged in a line.

[0036] In this embodiment, the supercharger 4 is an air compressor of a suitable model, which is delivered through the compressed air dry powder tank 3, so that the airflow carries the dry powder and sprays it out from the dry powder nozzle 5. The vehicle towing device 2 is a vehicle-mounted automatic winch (this vehicle-mounted automatic winch is existing technology, and most existing clearing trailers are equipped with it, so it will not be described in detail here).

[0037] In a preferred embodiment, a fire protection system is also included, which includes a fire hose reel 6 and a spray gun 7. The fire hose reel 6 is mounted on the lower end of the chassis, and a fire hose (a in the figure) that can be pulled out or retracted is wound on the fire hose reel 6. One end of the fire hose is connected to the dry powder tank 3, and the other end is connected to the spray gun 7.

[0038] In the above implementation plan, if the vehicle is on fire upon arrival at the destination, or if other vehicles or objects catch fire during the journey, emergency rescue can be carried out through this fire protection system. Specifically, after the vehicle is parked stably, the fire hose on the fire hose reel 6 is quickly pulled out, the booster 4 is turned on, and simultaneously, the spray gun 7 is held and sprayed with dry powder towards the fire point or an easily accessible location to achieve rapid rescue. This design integrates vehicle transportation, fire extinguishing of the transport vehicle battery, and daily firefighting, making it a very powerful system.

[0039] In this embodiment, two dry powder tanks 3 are provided and distributed on both sides of the lower part of the chassis. Each dry powder tank 3 is connected to a booster 4. The two dry powder tanks 3 are connected in series through a connecting pipe, and the automatic dry powder spray fire extinguishing assembly is connected to the connecting pipe through a pipeline. The dry powder tanks 3 are reasonably arranged, and the fire extinguishing effect of two dry powder tanks 3 is relatively long-lasting.

[0040] In this embodiment, the driver's cab of the aforementioned clearing vehicle 1 is provided with a storage room for storing fire-fighting supplies and tools. Specifically, a recessed storage room can be provided on one side of the driver's cab, and the storage room is equipped with a door or window that can be opened or closed, and can be used to store gas masks, fire suits, tools, etc.

[0041] In a preferred embodiment, one end of the trailer flatbed 13 is provided with a vertically upward extending guardrail 15, and a camera 16 is provided at the upper end of the guardrail 15. The camera 16 is connected to the control system of the cab of the wrecker vehicle body 1.

[0042] In the above implementation scheme, the control system has a display screen (located in the center console of the driver's cab), and a camera 16 is installed above the front end of the trailer flatbed 13 to observe the rescued vehicle on the trailer flatbed 13 in real time to see if the vehicle is on fire or other phenomena. The image is then displayed on the screen in real time so that the driver and passengers can observe the situation of the rescued vehicle behind them in a timely manner and make an emergency response.

[0043] As a preferred implementation method, such as Figure 5 The aforementioned chassis is provided with a trailer arm 8 at its rear end. The trailer arm 8 includes a first hydraulic cylinder 81 and a second hydraulic cylinder 82. The cylinder body of the first hydraulic cylinder 81 is hinged to the lower part of the rear end of the chassis, and the cylinder body of the second hydraulic cylinder 82 is hinged to the rear end of the chassis. The telescopic end of the second hydraulic cylinder 82 is connected to the upper part of the first hydraulic cylinder 81, and a trailer hook is connected to the telescopic end of the first hydraulic cylinder 81.

[0044] In the above implementation scheme, the tow arm 8 can tow a vehicle to be rescued at the rear of the vehicle, while simultaneously loading another vehicle to be rescued onto the trailer flatbed 13, achieving dual-vehicle rescue. Furthermore, during the rescue process, if only the vehicle needs to be moved, the extension of the first hydraulic cylinder 81, combined with the extension and retraction of the second hydraulic cylinder 82, adjusts the vertical tilting angle of the first hydraulic cylinder 81, ensuring accurate alignment and engagement between the tow hook and the towed vehicle. The design is ingenious and the operation is quite flexible.

[0045] In this embodiment, the trailer hitch can also be replaced by a product that supports the vehicle wheels (the vehicle's front wheels are hooked onto the upper part of this component, which is existing technology and will not be described in detail here).

[0046] In a preferred embodiment, the rear end of the trailer flatbed 13 is hinged with an overlap plate 131, which can be flipped upward to be vertical or flipped downward to be horizontal. The upper two sides of the trailer flatbed 13 are provided with windproof side plates 132 extending vertically upward along their edge lines.

[0047] In the above implementation scheme, the overlapping plate 131 can be flipped at a certain angle when the trailer flatbed 13 is tilted and landed, so that the vehicle can be better towed onto the trailer flatbed 13. At the same time, the overlapping plate 131 can be flipped up, and its position can be adjusted as needed during use, which is quite flexible.
