[0025] The principles and features of the present invention will be described below in conjunction with the attached drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0026] Example: As shown in Figure 1 、 2 、3, and 4, the obstacle-clearing fire truck of this embodiment includes an obstacle-clearing vehicle body 1 and a vehicle battery fire extinguishing system. A flat plate bracket 11 is hinged and installed on the chassis of the above-mentioned obstacle-clearing vehicle body 1. A first lifting oil cylinder 12 connected to the above-mentioned flat plate bracket 11 is installed on the above-mentioned chassis. A trailer flat plate 13 is slidably installed on the above-mentioned flat plate bracket 11. A push-pull oil cylinder 14 connected to the above-mentioned trailer flat plate 13 and pushing it to slide is provided on the above-mentioned flat plate bracket 11. Vehicle towing equipment 2 is provided at one end of the above-mentioned flat plate bracket 11 or trailer flat plate 13 close to the vehicle head. The above-mentioned vehicle battery fire extinguishing system includes a dry powder tank 3 and a dry powder automatic spraying fire extinguishing component. The above-mentioned dry powder automatic spraying fire extinguishing component is installed on the upper surface of the above-mentioned trailer flat plate 13 and is communicated with the above-mentioned dry powder tank 3 through a pipeline. A supercharger 4 communicated with the above-mentioned dry powder tank 3 is provided on the above-mentioned chassis.

[0027] During the use of the obstacle-clearing fire truck in this embodiment, the body 1 of the wrecker adopts the body structure of an existing wrecker and has the towing function of an existing wrecker. Specifically, when the entire vehicle drives in front of the target rescue vehicle, the first lifting cylinder 12 extends to drive the flat plate bracket 11 and the towing flat plate 13 to lift up (the front end of the vehicle head is lifted upwards). Next, the push-pull cylinder 14 drives the towing flat plate 13 to slide relative to the flat plate bracket 11 towards the parking space, so that the tail end of the towing flat plate 13 touches the ground. Next, it is connected to the vehicle to be rescued through the vehicle towing device 2, and then the vehicle to be rescued is towed forward onto the towing flat plate 13. After that, the towing flat plate 13 slides back to its original position, and the first lifting cylinder 12 contracts to make the flat plate bracket 11, the towing flat plate 13 and the vehicle thereon fall smoothly above the chassis. When a fire breaks out in the battery at the bottom of the vehicle to be rescued (especially an electric vehicle), the dry powder in the dry powder tank 3 is conveyed to the dry powder automatic spraying and extinguishing component through the supercharger 4, and a large amount of dry powder is sprayed onto the bottom of the vehicle through the dry powder automatic spraying and extinguishing component on the towing flat plate 13, so as to achieve the function of extinguishing fire during the transfer process, and the rescue safety is greatly improved. The overall design very much caters to the development of the modern automotive industry.

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

[0029] As a preferred embodiment, the above-mentioned dry powder automatic spraying and extinguishing component includes a dry powder nozzle 5 with a solenoid valve built in. A plurality of the above-mentioned dry powder nozzles 5 are embedded at intervals at the upper end of the above-mentioned towing flat plate 13. Each of the above-mentioned dry powder nozzles 5 is connected to a flow dividing chamber 51 through a pipeline. The flow dividing chamber 51 is communicated with the above-mentioned dry powder tank 3 through a pipeline. The solenoid valve and the supercharger 4 are respectively connected to the control system of the wrecker body 1.

[0030] In the above-mentioned implementation scheme, when it is necessary to extinguish fire during the transfer process, the control system controls the solenoid valve to open, and the supercharger 4 synchronously boosts the pressure, quickly conveying the dry powder in the dry powder tank 3 to the dry powder nozzle 5 and spraying it out, so as to quickly extinguish the fire in the battery at the bottom of the transfer vehicle (burning).

[0031] In this embodiment, a plurality of the above-mentioned dry powder nozzles 5 can be arranged at intervals in a row and installed in the middle area of the above-mentioned towing flat plate 13, or evenly distributed on the upper surface of the towing flat plate 13.

[0032] In this embodiment, the control system belongs to the original control in the cab of the wrecker body 1 and belongs to the prior art, so it will not be elaborated here.

[0033] As a preferred embodiment, a smoke sensor 52 is embedded at the position of the upper part of the above-mentioned towing flat plate 13 near each of the above-mentioned dry powder nozzles 5, and the smoke sensor 52 is connected to the control system.

[0034] In the above embodiments, when the vehicle battery on the transported vehicle (i.e., on the trailer flatbed 13) catches fire (re-ignites), a large amount of thick smoke is generated, which will be detected by the smoke sensor 52, and the detected signal will be sent to the control system. The control system will control the solenoid valve in the dry powder nozzle 5 to open and simultaneously control the booster 4 to operate, so as to quickly spray dry powder and carry out fire fighting in the first time. The response time is relatively short and the fire fighting is very timely.

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

[0036] In this embodiment, the above-mentioned booster 4 uses an air compressor of a suitable model, and conveys it into the dry powder tank 3 through compressed air, so that the airflow carries the dry powder and sprays out from the dry powder nozzle 5. The above-mentioned vehicle towing device 2 is an on-vehicle automatic winch (this on-vehicle automatic winch belongs to the prior art, and most of the existing breakdown tow trucks are equipped with it, so it will not be elaborated here).

[0037] As a preferred implementation manner, it further includes a fire fighting system. The above-mentioned fire fighting system includes a fire hose reel 6 and a spray gun 7. The above-mentioned fire hose reel 6 is installed at the lower end of the above-mentioned chassis. A retractable fire fighting pipeline (designated as a in the figure) is wound on the above-mentioned fire hose reel 6. One end of the above-mentioned fire fighting pipeline is connected to the above-mentioned dry powder tank 3, and the other end is connected to the above-mentioned spray gun 7.

[0038] In the above embodiments, when arriving at the destination for rescue, if the vehicle is on fire, or if other vehicles or objects catch fire during driving, the emergency rescue can be carried out through this fire fighting system. Specifically, after the vehicle is parked stably, quickly pull out the fire fighting pipeline on the fire hose reel 6, turn on the booster 4, and at the same time, hold the spray gun 7 and spray dry powder at the fire point or the easily rescueable direction, so as to achieve the purpose of rapid rescue. This design enables the entire vehicle to integrate vehicle transportation, vehicle battery fire extinguishing, and daily fire fighting, with very powerful functions.

[0039] In this embodiment, two above-mentioned dry powder tanks 3 are provided and distributed on both sides of the lower part of the above-mentioned chassis. Each of the above-mentioned dry powder tanks 3 is connected to one of the above-mentioned boosters 4. The two above-mentioned dry powder tanks 3 are connected in series through a connecting pipe, and the dry powder automatic spraying fire extinguishing assembly is connected to the above-mentioned connecting pipe through a pipeline. The layout of the dry powder tanks 3 is reasonable, and the fire fighting of the two dry powder tanks 3 is relatively lasting.

[0040] In this embodiment, a storage room for storing fire fighting articles and tools is provided on one side of the cab of the above-mentioned breakdown truck body 1. Specifically, a concave storage room can be set on one side of the cab. The storage room is provided with a door or window that can be opened or closed, and can be set to place gas masks, fire fighting suits, tools, etc. respectively.

[0041] As a preferred embodiment, a protective railing 15 extending vertically upward is provided at one end of the above-mentioned trailer flatbed 13, a camera 16 is provided at the upper end of the protective railing 15, and the camera 16 is connected to the control system of the cab of the breakdown truck body 1.

[0042] In the above-mentioned implementation scheme, the control system has a display screen (located in the middle control position of the cab), and a camera 16 is arranged above the head end of the trailer flatbed 13 to observe the vehicle to be rescued on the trailer flatbed 13 in real time, to check whether there is a fire or other phenomena on the vehicle, and then present the picture on the display screen in real time, so that the driver and passengers can timely observe the situation of the vehicle to be rescued at the rear and make timely emergency responses.

[0043] As a preferred embodiment, as Figure 5 described above, a trailer arm 8 is provided at the tail end of the above-mentioned chassis. The trailer arm 8 includes a first oil cylinder 81 and a second oil cylinder 82. The cylinder body of the first oil cylinder 81 is hinged to the lower part of the tail end of the chassis, the cylinder body of the second oil cylinder 82 is hinged to the tail end of the chassis, the telescopic end of the second oil cylinder 82 is joined to the upper part of the first oil cylinder 81, and a trailer hook is connected to the telescopic end of the first oil cylinder 81.

[0044] In the above-mentioned implementation scheme, the trailer arm 8 can tow a vehicle to be rescued at the rear of the vehicle, and at the same time, a vehicle to be rescued is also loaded on the trailer flatbed 13 to achieve double-vehicle rescue. At the same time, during the rescue process, if only the vehicle needs to be moved and towed away, the first oil cylinder 81 is extended, and the telescopic movement of the second oil cylinder 82 is used to adjust the up-and-down turning angle of the first oil cylinder 81, so that the trailer hook can be accurately aligned and hooked to the vehicle to be towed. The design is ingenious and the operation is relatively flexible.

[0045] In this embodiment, the trailer hook can also be replaced with a product that supports the vehicle wheel body (the front wheel of the vehicle is stuck on the upper part of this component, which belongs to the prior art and will not be elaborated here).

[0046] As a preferred embodiment, a lapping plate 131 is hinged to the tail end of the above-mentioned trailer flatbed 13. The lapping plate 131 can be turned upward to be vertical or turned downward to be horizontal. On both sides of the upper part of the trailer flatbed 13 along its edge line, there are windshield side plates 132 extending vertically upward.

[0047] In the above-mentioned implementation scheme, when the trailer flatbed 13 is tilted and lands, the lapping plate 131 can be turned by a certain angle to facilitate the towing of the vehicle onto the trailer flatbed 13. At the same time, the lapping plate 131 can be turned upward and can be turned and adjusted according to needs during use, which is relatively flexible.
