Description

Technical Field

[0001] The utility model belongs to the field of fire fighting devices, and specifically relates to a special cooling device for fire-causing power batteries of new energy vehicles. Background Art

[0002] With the popularization of new energy vehicles, the safety issue of new energy vehicle fires needs to be solved urgently. There are mainly two types of new energy vehicle fires. One is the fire of electrical circuits, which can be efficiently solved by using the on-board fire extinguisher; the other is the fire of power batteries, which is an oxygen-free combustion and ordinary fire extinguishers are ineffective, which is still a pain point in the industry.

[0003] Currently, the effective way is to spray the power battery with a large amount of water to cool it down. However, since the power battery is located at the bottom of the car and there are great safety hazards in the event of a power battery fire, it is extremely dangerous to artificially place a cooling device at the bottom of the car. Summary of the invention

[0004] The purpose of the utility model is to provide a special cooling device for a fire in a power battery of a new energy vehicle, which can be remotely transported to the bottom of the new energy vehicle on fire to extinguish the fire and cool the power battery. The transportation mechanism can be movably separated from the spraying mechanism and returned to a safe distance, which is safer and can also recycle waste water to improve utilization efficiency.

[0005] The technical solution is as follows:

Two fire hoses can be provided. The spray mechanism can be remotely transported to the bottom of the new energy vehicle power battery on fire through the transport mechanism. After arrival, the transport mechanism can be movably separated from the spray mechanism through the second connection part to prevent the electronic components inside the transport mechanism from being damaged in a high temperature environment, or even causing combustion to further stimulate and aggravate the fire, thereby ensuring the safety of the operating personnel and the cooling device. Then water is passed into one of the fire hoses, and the water flows to the spray head through the first connection part. The spray head extinguishes the fire and cools down the power battery on fire at the bottom of the vehicle. Due to the long cooling time, a return water pool is also provided on the outer ring of the spray head.
