Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile fire fighting, especially a fire fighting system for new energy automobile. BACKGROUND

[0002] New energy automobile refers to the automobile that uses unconventional vehicle fuel as power source (or uses conventional vehicle fuel, adopts new vehicle power device), and combines the advanced technology of vehicle power control and driving to form the automobile with advanced technical principle and new technology and structure.

[0003] The most common power source in new energy automobiles is ternary lithium battery, which has a cruising range of about 300-400 kilometers. When the battery runs out, it needs to be charged at a charging station before it can be used again. When the battery quality is not up to standard or the vehicle is assembled with mismatched batteries, it is easy to catch fire when charging.

[0004] The existing fire extinguishing device, such as various fire extinguishers, can only manually extinguish the fire when the fire occurs. Triggered fire extinguishing devices can extinguish the fire to some extent, but cannot prevent the spread of the fire. When the vehicle catches fire, other vehicles may also catch fire, and the lithium battery fire is a heat-releasing chemical reaction that continuously releases heat, producing a large amount of smoke first, and then producing an open flame when the temperature reaches the ignition point, which may cause a fire. The existing fire extinguishing devices cannot effectively prevent this process, and the vehicle may be burned to the point of being scrapped and cannot be repaired.

[0005] Prior art (publication number: CN112354104A, publication date: 2021.02.12) discloses a new energy automobile charging automatic fire extinguishing device, which can quickly submerge the automobile into the water tank before the battery of the new energy automobile self-ignites and when the smoke is generated. The tail of the automobile is quickly cooled by the water in the water tank, and the fire is extinguished. The head of the automobile is not submerged in water, reducing the damage to the vehicle.

[0006] However, the above-mentioned scheme needs to submerge the whole vehicle to achieve fire extinguishing. Not only does the water tank need to occupy a large space, but it also has the problem of being difficult to install in a parking lot for use. Moreover, the vehicle will inevitably have various problems after being soaked in water.
