Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically relating to a fire protection device for new energy electric vehicles used in parking lots. Background Technology

[0002] With the increasing popularity of new energy vehicles, spontaneous combustion accidents involving electric vehicles in parking lots or charging stations are frequent, especially in underground parking lots where the enclosed space makes it difficult for fire trucks to quickly intervene, leading to the easy spread of fires and causing serious damage. When lithium batteries catch fire, the internal chemical reaction does not require oxygen, and traditional fire extinguishers (such as dry powder and carbon dioxide) cannot effectively extinguish the fire, while water-based fire extinguishing agents may accelerate the reaction.

[0003] To prevent the spread of fires after they occur in electric vehicles, current technology involves setting up fireproof compartments in parking spaces to enclose the electric vehicles, which can help extinguish fires and prevent their spread. However, setting up a fireproof compartment in each parking space is not only costly but also takes up parking space. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a fire-fighting device for new energy electric vehicles used in parking lots. This invention incorporates a vehicle body sealing mechanism via a position adjustment component on a moving mechanism. When a fire occurs, the fire-fighting equipment located in a fire truck space or other location is moved to the burning vehicle using the moving mechanism. By operating the first and second operating levers, the vehicle body sealing mechanism is moved to the burning vehicle, sealing it to extinguish the fire and prevent its spread. The fire-fighting equipment does not need to be installed in every parking space, reducing costs and the area occupied in the parking lot.

[0005] According to some embodiments, this utility model provides a fire-fighting device for new energy electric vehicles in parking lots, adopting the following technical solution:

[0030] Specifically, the vehicle body sealing mechanism 2 can seal the electric vehicle that is on fire, thereby achieving the purpose of isolation.

[0031] like Figure 2 As shown, the adjustment component 201 can adjust the position of the body sealing component 202 so that the body sealing component 202 is adjusted to the top of the moving mechanism 1 and the top of the electric vehicle 5. The adjustment component 201 can be a telescopic rod or a telescopic frame. In one embodiment, the position adjustment component 201 includes a first operating rod 2011, a first rotating connector 2012, a second operating rod 2013, and a second rotating connector 2014. Optionally, two first operating rods 2011 are provided on the housing 102 by welding or other means. The first operating rods 2011 can be fixed rods or telescopic rods. A certain angle is provided between the first operating rods 2011 and the housing 102. Each first operating rod 2011 is provided with a second operating rod 2013 through the first rotating connector 2012. The end of the second operating rod 2013 away from the first operating rod 2011 is rotatably connected to the vehicle body sealing component 202 through the second rotating connector 2014. The first rotating connector 2012 and the second rotating connector 2014 are rotating connectors that can rotate within a certain angle range.

[0032] In one embodiment, the second rotating connector 2014 is rotated manually or with the aid of other operating equipment, causing the body sealing assembly 202 to move from the top of the moving mechanism 1 to the top of the electric vehicle 5. In another embodiment, both the first rotating connector 2012 and the second rotating connector 2014 are configured as motors or other power devices, capable of automatically changing the angle between the first operating lever 2011 and the second operating lever 2013, and automatically changing the angle between the second operating lever 2013 and the body sealing assembly 202.

When in operation, the isolation plate 302 can be pulled to the bottom of the electric vehicle 5 by firefighters to provide isolation. Two limiting blocks can be provided on the isolation plate 302, respectively at the two ends of the slide rails 3012, to prevent the isolation plate 302 from detaching from the slide rails 3012. The isolation plate 302 can be made of inorganic mineral, fiber-reinforced, or resin-based composite fireproof material, such as ceramic fiber composite material.
