[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described below in conjunction with the accompanying drawings and embodiments.

[0027] In the past, when fires occurred in new energy electric vehicles, they were usually extinguished by fire-fighting water or foam extinguishing agents. However, due to the instability of lithium batteries, which are prone to reignition or even explosion, it is difficult to isolate oxygen and thus cannot effectively extinguish the fire.

[0028] This application provides a new energy electric vehicle accident handling and transport vehicle that can tow a burning accident vehicle into a sealed cavity and isolate it from oxygen, cool it down, and extinguish the fire, thus extinguishing the fire while avoiding damage to the surrounding environment.

[0029] See Figures 1-7 As shown, the new energy electric vehicle accident handling and transfer vehicle provided in this embodiment includes: vehicle body 10, cargo compartment 20 and fire-fighting equipment 30.

[0030] The vehicle body 10 includes a cab 11, a chassis 12, and multiple wheels 13. The cab 11 is located at the front end of the chassis 12, and the multiple wheels 13 are rotatably mounted on the bottom of the chassis 12.

[0031] In this embodiment, a fuel engine or an electric motor is typically installed in front of the cab 11. By controlling the cab 11, the fuel engine or electric motor can be controlled to drive the wheels 13 to rotate and steer via a transmission mechanism, thereby controlling the movement or steering of the vehicle body 10. In other words, after towing the burning vehicle into the cavity, it can be moved by the vehicle body 10 to an open area away from crowds or important buildings to prevent damage to other people or buildings caused by the explosion.

[0032] The carriage 20 is mounted on the chassis 11. The carriage 20 includes a first body 21, a flexible connection assembly 22, a second body 23, a door 24, a traction mechanism 25, and a tilting drive assembly 26. The first body 21 and the second body 23 are connected by the flexible connection assembly 22. The door 24 is located at the rear end of the second body 23. The door 24, the second body 23, the flexible connection assembly 22, and the first body 21 form a receiving cavity 200. The traction mechanism 25 is installed in the receiving cavity 200. The tilting drive assembly 26 is installed between the chassis 11 and the first body 21. The tilting drive assembly 26 drives the carriage 20 upwards and towards the rear end of the chassis 11, so that the rear end of the second body 23 contacts the ground, and keeps the first body 21, the flexible connection assembly 22, and the second body 23 in a tilted state. The traction mechanism 25 is used to tow the accident vehicle into the receiving cavity 200.

[0033] Specifically, the rear end of the second box 23 has an opening, and a door 24 is installed at this opening, which can be closed or opened. When it is necessary to tow the accident vehicle, the door 24 is opened, and at the same time, the opening at the rear end of the second box 23 is kept facing the front or rear of the accident vehicle. The tilting drive assembly 26 drives the box 20 upward and towards the rear end of the chassis 11, so that the rear end of the second box 23 contacts the ground, and the first box 21, the soft connection assembly 22, and the second box 23 are kept in a tilted state. Then, the towing mechanism 25 tows the accident vehicle into the cavity 200.

[0034] In this embodiment, the first box 21 and the second box 22 are both made of explosion-proof materials. Furthermore, the inner walls of the first box 21, the second box 22, and the door 24 are also provided with a high-temperature resistant layer to prevent the heat of the burning accident vehicle from being transferred to the outer wall of the compartment through the inner wall.

[0035] The fire-fighting device 30 includes: a first spray assembly 31, a second spray assembly 32, an inert gas supply mechanism 33, a fire water supply mechanism 34, and a filter and exhaust mechanism 35. The first spray assembly 31 is located at the top of the receiving cavity 200 and can be used to spray onto the top of the accident vehicle to reduce its temperature. The second spray assembly 32 is located at the bottom of the receiving cavity 200 and can be used to spray onto the bottom of the accident vehicle to reduce its temperature. The inert gas supply mechanism 33 is installed on the outer wall of the first housing 21 or the second housing 23 and is used to supply inert gas to the receiving cavity 200 to displace oxygen within it. The fire water supply mechanism 34 is installed on the outer wall of the first housing 21 or the second housing 23 and is used to supply fire water or foam extinguishing agent to the receiving cavity 200. When the amount of fire water or foam extinguishing agent in the receiving cavity 200 reaches a certain level, the chassis of the accident vehicle can be submerged in fire water to achieve better cooling and fire extinguishing effects. A filter exhaust mechanism 35 is installed on the door 24. This filter exhaust mechanism 35 is used to exhaust and filter toxic gases produced by the accident vehicle within the cavity.

[0036] In this embodiment, when inert gas is supplied to the cavity 200 through the inert gas supply mechanism 33, the door 24 is closed with a small gap. Then, the inert gas supply mechanism 33 operates to supply inert gas into the cavity 200. The air in the cavity 200 will be squeezed out to the outside of the carriage 20 through the gap, thereby reducing the oxygen content in the cavity 200 and achieving the effect of indirect fire extinguishing.

[0037] In a preferred embodiment, the inert gas supply mechanism 33 can supply nitrogen to the cavity 200. Of course, in other embodiments, other inert gases can also be used, and the specific choice can be made according to actual needs.

[0038] In one embodiment of this application, one end of the first housing 21 is closed and the other end has a first opening. The two ends of the second housing 23 each have a second opening. The flexible connection component 22 is a frame-type flexible connector, with one end connected to the first opening and the other end connected to the second opening at one end of the second housing 23. The door 24 is installed at the second opening at the other end of the second housing 23. This forms the carriage 20. The frame-type flexible connector is elastic, such as... Figure 5 As shown, when the first housing 21 and the second housing 23 are in an inclined state, the frame-type flexible connector extends from top to bottom, as... Figures 1-3 As shown, when the first housing 21 and the second housing 23 are reset, the frame-type flexible connector retracts and resets.

[0039] To ensure that the frame-type flexible connector can withstand the weight of the accident vehicle during towing, in this embodiment, the carriage 20 further includes: a telescopic support plate structure (not shown in the figure). The two ends of the telescopic support plate structure are rotatably connected to the bottom of the first opening of the first box 21 and the bottom of the second opening at one end of the second box 23, respectively, and are located at the inner bottom or bottom of the frame-type flexible connector. The telescopic support plate structure can extend with the extension of the frame-type flexible connector and contract with the contraction of the frame-type flexible connector.

[0040] Understandably, the telescopic support plate structure can work with the first box 21 and the second box 2 to support the weight of the accident vehicle in both the telescopic and retracted states.

[0041] To facilitate monitoring of the status of the accident vehicle within the 200-cubic-meter cavity, such as Figures 6-8 As shown, the new energy electric vehicle accident handling and transport vehicle provided in this embodiment also includes a video monitoring mechanism 40, which includes a camera 41, a display 42, and a signal transmission module 43. The camera 41 is preferably a high-temperature resistant and explosion-proof camera, installed inside the cavity 200. The display 42 and signal transmission module 43 are installed inside the driver's cab 11, and both are connected to the camera 41. The camera 41 is used to capture video within the cavity 200 and generate a video signal, which is a video of the accident vehicle. The display 42 is used to convert the video signal into video so that operators in the driver's cab 11 can observe the fire and firefighting situation of the accident vehicle and take timely adaptive measures, such as increasing the amount of fire-fighting water. The signal transmission module 43 is used to transmit the video signal to a data center, which is a fire control center, allowing personnel in the fire control center to view the status of the accident vehicle for timely and effective command.

[0042] In order to avoid unnecessary injury to other people by getting close during the handling of accident vehicles, the new energy electric vehicle accident handling and transfer vehicle provided in this embodiment also includes: multiple sound and light warning lights 50. The multiple sound and light warning lights 50 are installed on the outer wall of the first box 21 and / or the second box 23. The sound and light warning lights 50 can flash warning lights and play warning audio at preset intervals to warn other people not to approach the transfer vehicle.

[0043] like Figure 4 , Figure 6 and Figure 7As shown, the fire-fighting device 30 also includes a water storage tank 36, which is disposed inside the accommodating cavity 200. Specifically, the water storage tank 36 is positioned at a height sufficient to avoid accident vehicles. The water storage tank 36 is connected to the first spray assembly 31 and the second spray assembly 32. The water storage tank 36 is used to store fire-fighting water. Of course, foam extinguishing agent can also be stored in the water storage tank 36. In cases where fire-fighting water or foam extinguishing agent cannot be provided to the first spray assembly 31 and the second spray assembly 32 through fire hydrants, fire-fighting water or foam extinguishing agent can be provided to the first spray assembly 31 and the second spray assembly 32 by temporarily storing water in the water storage tank 36.

[0044] A water injection valve 361, which communicates with the water storage tank 36, is also provided on the outer wall of the first housing 21 or the second housing 23. This water injection valve 361 is used to connect to an external fire water pipe to inject fire water into the water storage tank 36, thereby replenishing the fire water supply. Of course, this water injection valve 361 can also be connected to a fire hydrant for water replenishment.

[0045] When the vehicle is burning, the gas pressure inside the cavity 200 increases. In this embodiment, a pressure relief valve 37 is provided on the first housing 21 and / or the second housing 22. The pressure relief valve 37 is used to relieve pressure when the internal pressure of the cavity 200 is greater than a preset value, so as to reduce the internal pressure.

[0046] like Figure 2 As shown, the fire-fighting device 30 also includes a toxic and harmful gas detection sensor 38, which is installed on the first housing 21 and / or the second housing 23. The toxic and harmful gas detection sensor 38 is connected to the filter exhaust mechanism 35. The toxic and harmful gas detection sensor 38 is used to detect the concentration of toxic and harmful gases in the cavity 200, and when the concentration of toxic and harmful gases is greater than a preset concentration, the filter exhaust mechanism 35 is activated or its power is increased to filter and discharge the toxic and harmful gases.

[0047] Of course, in summary, the fire-fighting device 30 also includes a temperature and humidity detection sensor 39, which is used to detect the temperature and humidity inside the cavity 200 to further determine the temperature inside the cavity 200, thereby determining whether the accident vehicle is still burning.

[0048] like Figures 1-4 , Figure 6 and Figure 7 As shown, the top of the first housing 21 and / or the second housing 23 is provided with an openable or closable exhaust window 211 to discharge the high-temperature gas inside after the fire is extinguished, thereby rapidly cooling the environment. The exhaust window 211 is preferably located on the top of the first housing 21 and / or the second housing 23.

[0049] In this embodiment, the inert gas supply mechanism 33 is installed on the top of the first housing 21, and exhaust windows 211 are provided on the top of both the first housing 21 and the second housing 23. To facilitate the operation of the inert gas supply mechanism 33 and the exhaust windows 211, a ladder 26 is provided on the outer wall of the first housing 21 and / or the second housing 23. The ladder 26 is arranged vertically to facilitate the operator to climb to the top of the carriage 20 via the ladder 26.

[0050] In summary, the new energy electric vehicle accident handling and transport vehicle provided by this invention, in practical applications, can tow the accident vehicle into the cavity via a traction mechanism, and then transport the accident vehicle to an open area away from crowds for handling, thus preventing safety accidents. During handling, inert gas is injected into the cavity via an inert gas supply mechanism to displace the oxygen inside and reduce combustion conditions. Afterwards, the doors are closed, and toxic gases are filtered and discharged via an exhaust filtration mechanism. Firefighting water is sprayed onto the top of the accident vehicle using a first spray assembly to cool it down, and firefighting water is sprayed onto the bottom of the accident vehicle using a second spray assembly to cool it down.

[0051] The above description, in conjunction with specific embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the inventive concept of this application.
