Abstract
Description
Technical Field
[0001] The utility model relates to a special fire-fighting vehicle dedicated to electric vehicles. Background Art
[0002] Electric vehicles are powered by power batteries. Existing electric vehicles usually use lithium batteries as their power batteries. Lithium batteries are prone to combustion, and lithium batteries contain oxidants that are not easy to extinguish after combustion. Therefore, electric vehicles are difficult to extinguish after combustion, and firefighting is difficult. This is a safety hazard that electric vehicles urgently need to address.
[0003] Fire trucks are the main firefighting tools of the fire brigade. Fire trucks have their own water tanks and use high-pressure water guns to spray water jets to extinguish fires. However, due to the combustion characteristics of electric vehicles, spraying water has no effect on the combustion of lithium batteries. It can only play a cooling role. The fire extinguishing effect is poor and cannot prevent the spread of fire. Summary of the Invention
[0004] In view of the above-mentioned deficiencies, the present invention provides a special fire-fighting vehicle for electric vehicles, which can prevent the fire from spreading when the electric vehicle battery burns.
[0005] In order to achieve the above purpose, the utility model adopts a special fire-fighting vehicle dedicated to electric vehicles, including a body, a water tank and a grabbing and lifting device are provided on the body, the grabbing and lifting device is arranged on the body inside the water tank, the grabbing and lifting device includes a rotating seat, a lifting seat, a retractor, a lifting arm, a lifting rope, and a hook. The rotating seat is arranged on the body, the lifting seat is arranged on the rotating seat and rotates, the end of the lifting arm is hinged on the lifting seat, the lifting rope is wound in the retractor, the lifting rope hangs downward from the front end of the lifting arm, and the hook is connected to the top of the lifting rope.
[0006] The utility model is further configured such that the boom includes an outer arm, a middle arm, and an inner arm. The middle arm is telescopically sleeved inside the outer arm, and the inner arm is telescopically sleeved inside the middle arm. The end of the outer arm is connected to the lifting seat, and a pulley seat is provided at the front end of the inner arm. The lifting rope passes through the pulley seat and hangs downward.
[0007] The utility model is further configured such that the retractor is arranged behind the lifting seat.
[0008] The water tank of this utility model is designed with a larger bottom area than the electric vehicle and is filled with water sufficient to submerge the vehicle. In the event of a fire in an electric vehicle, the vehicle is captured by a lifting device and placed in the water tank. The water in the tank submerges the vehicle, cooling it and preventing the lithium battery from igniting other parts of the vehicle. The hook of this utility model can also be an electromagnet.
[0009] The beneficial effect of the utility model is that the electric vehicle is placed as a whole in the water tank through the grabbing and lifting device, the electric vehicle is cooled, and the burning lithium battery is placed to ignite other parts of other electric vehicles and surrounding flammable items.

[0011] Figure 2 It is a top view of the first state of a specific embodiment of the utility model.
[0012] Figure 3 It is a top view of the second state of a specific embodiment of the utility model. DETAILED DESCRIPTION
[0013] like Figures 1 to 3 As shown, a specific embodiment of the present utility model is a special fire-fighting vehicle for electric vehicles, comprising a vehicle body 1, on which a water tank 2 and a grabbing and lifting device 3 are provided. The grabbing and lifting device 3 is provided on the vehicle body 1 inside the water tank 2, and the grabbing and lifting device 3 comprises a rotating seat 31, a lifting seat 32, a retractor 33, a lifting arm 34, a lifting rope 35, and a hook 36. The rotating seat 31 is provided on the vehicle body 1, and the lifting seat 32 is provided to rotate on the rotating seat 31. The end of the lifting arm 34 is hinged on the lifting seat 32, and the retractor 33 is provided. It is arranged behind the lifting seat 32, and one end of the lifting rope 35 is wound in the retractor 33. The lifting rope 35 hangs downward from the front end of the lifting arm 34. The lifting arm 34 includes an outer arm 341, a middle arm 342, and an inner arm 343. The middle arm 342 is telescopically sleeved in the outer arm 341, and the inner arm 343 is telescopically sleeved in the middle arm 342. The end of the outer arm 341 is connected to the lifting seat 32, and the front end of the inner arm 343 is provided with a pulley seat 344. The lifting rope 35 passes through the pulley seat 344 and hangs downward, and the hook 36 is connected to the top of the lifting rope 35.
[0014] The water tank 2 of the utility model is designed to have a larger bottom area than the electric vehicle, and the water tank 2 is filled with water that can cover the electric vehicle. When the electric vehicle 4 is on fire, the electric vehicle 4 can be grabbed by the grabbing device (such as Figure 2 As shown), the electric vehicle 4 is placed in the water tank 2, and the water in the water tank 2 submerges the electric vehicle 4 (as shown Figure 3 As shown), the electric vehicle 4 is cooled to prevent the lithium battery from igniting other parts of the electric vehicle 4 and surrounding flammable items.
[0015] The hook 36 of the present invention can also be an electromagnet or a movable mechanical claw.
