Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to a multi-functional vehicle fire extinguishing device. Background Technology

[0002] In real life, vehicle fires are becoming increasingly common. During a vehicle fire, fire extinguishers and other fire-fighting devices are usually used to assist in extinguishing the fire, thereby enabling the fire to be put out quickly and reducing property damage.

[0003] In practical work, the existing fire extinguishing devices have relatively complete structures and functions, which can meet basic usage requirements, but the following problems still exist:

[0004] In actual use, due to the diversity and complexity of car fires, such as the frequent fires of truck tires and the high probability of fires in the chassis and battery packs of cars and new energy vehicles, traditional fire extinguishers cannot extinguish fires according to different situations. At the same time, fire extinguishers need to be held close to the car and operated continuously to extinguish fires, which reduces the overall safety and makes it inconvenient to target fires in the chassis, tires and battery packs.

[0005] Therefore, this utility model provides a multi-functional vehicle fire extinguishing device. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a multi-functional vehicle fire extinguishing device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a multi-functional vehicle fire extinguishing device, including a chassis fire extinguishing structure, a tire fire extinguishing structure, a T-pipe, and a connecting pipe. The chassis fire extinguishing structure and the tire fire extinguishing structure are fixedly installed to the T-pipe via the connecting pipe. The chassis fire extinguishing structure includes a galvanized pipe, which consists of a rectangular tube body and three straight pipes equidistantly fixed to the inner wall of the rectangular tube body. One side of the galvanized pipe is provided with three first clamping interfaces and two connecting round pipes. The tire fire extinguishing structure includes a T-shaped pipe, the bottom end of which is equipped with a second clamping interface, which is fixedly installed to the connecting pipe. Both ends of the T-shaped pipe are fixedly connected to two corrugated pipes, and one end of each corrugated pipe is fixedly connected to a round steel pipe.

[0008] In a preferred embodiment, the two connecting round pipes are connected by a first clamping interface, and one end of the two connecting round pipes is connected to two other first clamping interfaces. One of the first clamping interfaces is installed with a galvanized pipe, and the other first clamping interface is fixedly installed with a connecting pipe. A universal nozzle is fixedly installed on the top of the rectangular tube body of the galvanized pipe, and the number of the universal nozzles is sixteen. A one-way nozzle is fixedly connected to the top of the straight tube of the galvanized pipe body, and the number of the one-way nozzles is twelve.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the first card interface, the connecting pipe and the galvanized pipe can be connected, and at the same time, under the action of the one-way nozzle and the universal nozzle, a water mist coverage can be formed, thereby quickly cooling and extinguishing the chassis and battery pack.

[0010] In a preferred embodiment, a first fixing plate is fixedly connected to the four corners of the bottom of the galvanized pipe, a second fixing plate is provided at the bottom of the first fixing plate, and a caster wheel is fixedly installed at the bottom of the second fixing plate. A first screw hole is opened on the inner wall of the first fixing plate, a second screw hole is opened on the inner wall of the second fixing plate, and a threaded clamp is threadedly connected to the inner wall of the first screw hole and the second screw hole.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the first fixed plate and the second fixed plate, the casters can be installed, which in turn allows the galvanized pipe to be moved with assistance, thereby enabling the galvanized pipe to move to the car chassis and battery pack for fire extinguishing.

[0012] In a preferred embodiment, an electric telescopic rod is fixedly installed on the outer surface of the T-shaped tube. A first steel rope is fixedly connected to the output end of the electric telescopic rod. Two springs are symmetrically fixedly connected to one end of the first steel rope. A second steel rope is fixedly connected to one end of each spring. A fixing ring is fixedly connected to the outer surface of the circular steel tube. The second steel rope is fixedly connected to the fixing ring.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the electric telescopic rod, the first steel rope can be driven to move, which in turn can drive the spring to move, which in turn can cooperate with the second steel rope, which can adjust the position of the circular steel pipe, which can then move to a suitable position, and thus extinguish the fire on the tire.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. For the vehicle chassis cooling device, galvanized pipes, 16 universal nozzles, 12 one-way nozzles, 4 universal wheels, and 3 first-clamp connectors are used for connection; for the vehicle tire fire extinguishing device, round steel pipes, stainless steel corrugated pipes, and electric telescopic rods are used, so that different fire extinguishing structures can be selected for fire extinguishing according to different fire extinguishing situations.

[0016] 2. Connect the fire truck to the fire hose for water supply; after the device outputs water, push it under the burning vehicle; the device can be modified for different sized vehicles, such as using the omnidirectional nozzle to create a water mist coverage at different angles. The main body of the device can be disassembled and assembled quickly and easily, and can be used to deal with fires of different sized vehicles. The omnidirectional nozzle and the one-way nozzle can be adjusted to two modes: hot water spray and direct water flow. This can cool the vehicle's battery pack from all angles, reduce the battery pack temperature, and achieve the purpose of extinguishing the fire.

[0017] 3. After the device starts spraying water, the rescuers operate the controller to adjust the angle of the circular steel pipe and accurately place it on the tire gaps or axle of the accident vehicle. The circular steel pipe of the device continuously sprays fine water jets to extinguish and cool the tires. During the fire extinguishing process, the rescuers can use a remote control to operate the device remotely. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown, this embodiment provides a technical solution: a multi-functional vehicle fire extinguishing device, including a chassis fire extinguishing structure 3, a tire fire extinguishing structure 4, a T-pipe 1, and a connecting pipe 2. The chassis fire extinguishing structure 3 and the tire fire extinguishing structure 4 are fixedly installed to the T-pipe 1 via the connecting pipe 2. The chassis fire extinguishing structure 3 includes a galvanized pipe 31, which consists of a rectangular pipe body and three straight pipes equidistantly fixed to the inner wall of the rectangular pipe body. One side of the galvanized pipe 31 is provided with three first clamping interfaces 32 and two connecting round pipes 33. The tire fire extinguishing structure 4 includes a T-shaped pipe 41, with a second clamping interface 42 installed at the bottom end of the T-shaped pipe 41. The first / second clamping interfaces are used for... The fire extinguishing device has a 40-pin connector, a second pin connector 42, and a connecting pipe 2. Both ends of the T-shaped pipe 41 are fixedly connected to two corrugated pipes 45. One end of the corrugated pipe 45 is fixedly connected to a round steel pipe 46, which is a galvanized steel pipe. For the vehicle chassis cooling device, a galvanized pipe 31, 16 universal sprinkler heads 34, 12 one-way sprinkler heads 35, 4 universal wheels 37, and 3 first pin connectors 32 are used for connection. For the vehicle tire fire extinguishing device, a round steel pipe 46, a stainless steel corrugated pipe 45, and an electric telescopic rod 43 are used. Thus, different fire extinguishing structures can be selected for fire extinguishing according to different fire extinguishing situations. Water is supplied to the fire truck via a fire hose; after the device dispenses water, it is pushed under the burning vehicle. The device can be modified for different vehicle sizes; for example, the omnidirectional nozzle 34 can spray water at different angles to create a water mist coverage. The main body of the device can be disassembled and reassembled quickly and easily to handle fires involving vehicles of different sizes. The omnidirectional nozzle 34 and the unidirectional nozzle 35 can be adjusted to either a hot spray or a direct stream, allowing for comprehensive cooling of the vehicle's battery pack and reducing its temperature to extinguish the fire. After the device dispenses water, rescuers operate the controller to adjust the angle of the circular steel pipe 46, accurately placing it in the tire gaps or on the axle of the vehicle. The circular steel pipe 46 continuously sprays a fine jet of water to extinguish and cool the tires. During the firefighting process, rescuers can use a remote control to operate the device remotely.

[0026] Going a step further, such as Figures 2-3As shown: Two connecting round pipes 33 are connected by a first clamping interface 32. One end of the two connecting round pipes 33 is connected to two other first clamping interfaces 32. One first clamping interface 32 is installed with a galvanized pipe 31, and the other first clamping interface 32 is fixedly installed with a connecting pipe 2. A universal nozzle 34 is fixedly installed on the top of the rectangular pipe body of the galvanized pipe 31. There are sixteen universal nozzles 34. A one-way nozzle 35 is fixedly connected to the top of the straight pipe of the galvanized pipe body 31. There are twelve one-way nozzles 35. Under the action of the first clamping interface 32, the connecting pipe 2 and the galvanized pipe 31 can be connected. At the same time, under the action of the one-way nozzles 35 and the universal nozzles 34, a water mist coverage is formed, thereby quickly cooling and extinguishing the chassis and battery pack.

[0027] The above solutions also have the problem that the galvanized pipe 31 is not easy to move, and therefore cannot be easily moved to the car chassis. Figure 2 and Figure 3 As shown: In this scheme, a first fixing plate 36 is fixedly connected to the four corners of the bottom of the galvanized pipe 31. A second fixing plate 38 is provided at the bottom of the first fixing plate 36. A caster wheel 37 is fixedly installed at the bottom of the second fixing plate 38. A first screw hole 39 is opened on the inner wall of the first fixing plate 36, and a second screw hole 310 is opened on the inner wall of the second fixing plate 38. A threaded clamp 311 is threadedly connected to the inner wall of the first screw hole 39 and the second screw hole 310. Under the action of the first fixing plate 36 and the second fixing plate 38, the caster wheel 37 can be installed, thereby assisting the movement of the galvanized pipe 31, so that the galvanized pipe 31 can move to the car chassis and battery pack for fire extinguishing.

[0028] The above solutions also have the problem that galvanized pipe 31 and other structures cannot be used for fire extinguishing of automobile tires. Figure 4 As shown, an electric telescopic rod 43 is fixedly installed on the outer surface of the T-shaped tube 41. A first steel rope 44 is fixedly connected to the output end of the electric telescopic rod 43. Two springs 49 are symmetrically fixedly connected to one end of the first steel rope 44. A second steel rope 48 is fixedly connected to one end of the springs 49. A fixing ring 47 is fixedly connected to the outer surface of the circular steel tube 46. The second steel rope 48 is fixedly connected to the fixing ring 47. Under the action of the electric telescopic rod 43, the first steel rope 44 can be driven to move, which in turn can drive the springs 49 to move, which in turn can cooperate with the second steel rope 48 to adjust the position of the circular steel tube 46, which can then move to a suitable position to extinguish the fire on the tire.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] When it is necessary to cool down and extinguish fires in the chassis and battery pack of a vehicle: At this time, the galvanized pipe 31 is moved to the chassis or battery pack of the vehicle through the caster wheel 37. The galvanized pipe 31 is then connected to the connecting pipe 2 and the three-way pipe 1 (each of the three branches of the three-way pipe 1 is equipped with a water control valve) through the first clamping interface 32 and the connecting round pipe 33. Then, it is connected to the external fire truck or fire hydrant through the three-way pipe 1. At this time, fire extinguishing operations are performed through the one-way nozzle 35 and the universal nozzle 34.

[0032] When it is necessary to extinguish the fire on the vehicle's tires, the T-shaped pipe 41 is connected to the connecting pipe 2 and the three-way pipe 1 through the second clamp interface 42. At this time, the electric telescopic rod 43 is activated, so that the first steel rope 44 can pull the spring 49 and the second steel rope 48, thereby driving the circular steel pipe 46 to move, causing the corrugated pipe 45 to deform, thereby changing the position of the circular steel pipe 46 to fit the tire and extinguish the fire.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
