Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a new energy vehicle cooling and fire extinguishing cart. Background Art

[0002] With the rapid development of social economy, people's environmental awareness is constantly improving. In the development of the automobile industry, gasoline and diesel engines are gradually abandoned, and various new energy vehicles are emerging. However, fire safety problems of new energy vehicles occur from time to time, posing a serious threat to people's lives and property safety, and feasible measures should be actively adopted to solve them. Usually, fires in new energy battery vehicles are mainly caused by batteries. The characteristics of fires are mainly reflected in the difficulty of handling, long fire extinguishing time, and fast burning speed. Therefore, it is advisable to adopt corresponding fire prevention measures at the early stage of the fire.

[0003] Since the battery of a new energy electric vehicle is usually located in the middle of the vehicle chassis, two methods are usually used to prevent fires in the early stages of the fire:

[0004] 1. Turn the new energy vehicle over to extinguish the fire. This method requires the use of large-scale lifting machinery. The operation is cumbersome and time-consuming, delaying the best time to extinguish the fire. Therefore, this method is not very practical.

[0005] 2. Firefighters hold fire hoses and spray water in a low crawling position. Since the chassis of the battery vehicle is relatively low from the ground, usually only 20 cm, this method is limited by the firefighters' line of sight and the spray angle of the water gun. This method wastes a lot of water and cannot effectively extinguish fires at various locations under the vehicle chassis.

[0006] In summary, a new energy vehicle cooling and fire extinguishing cart is proposed to facilitate the cooling and fire extinguishing of new energy battery vehicles in the early stage of fire. Utility Model Content
