Description

Technology Field

[0001] The present invention relates to a fire extinguishing device for a vehicle equipped with a fire extinguishing curtain. Background Technology

[0003] With the recent rapid proliferation of electric vehicles, charging systems are being installed in parking lots of multi-unit dwellings such as apartments; however, as the number of electric vehicles increases every year, vehicle fire accidents are also rising.

[0004] If a fire occurs in an electric vehicle or spreads to other vehicles, serious situations may arise, such as battery explosions or damage to dozens to hundreds of vehicles due to the nature of underground parking lots; therefore, fire safety measures are urgently needed.

[0005] In particular, thermal runaway from electric vehicle batteries can cause significant damage to building structures or piping installed within the building, so countermeasures are necessary.

[0006] In addition, batteries installed in electric vehicles are formed by bundling numerous waterproof secondary batteries, which presented a problem in that they are difficult to extinguish with ordinary fire extinguishers and the fire can only be suppressed when the entire battery is incinerated.

[0007] Conventional fire suppression equipment installed on the ceiling of parking lots to address this issue had the problem that, when a vehicle fire occurred, it only sprayed fire extinguishing water on the exterior of the vehicle and nearby vehicles, making it difficult to suppress the fire inside the vehicle in the early stages, and was insufficient in preventing secondary damage such as fire spreading to nearby vehicles due to flames or fire radiant heat, and fuel tank explosions.

[0008] In addition, batteries used in electric vehicles are mounted in the lower part of the vehicle body. Therefore, even if firefighting water is sprayed from the top or side of the electric vehicle, it does not reach the lower part of the vehicle body, resulting in a problem where the battery cannot be completely extinguished.
