电动自行车充电车棚火灾防控技术研究

Research on fire prevention and control technology for electric bicycle charging shed

本文针对电动自行车充电车棚车辆起火问题,研发了专用型水系泡沫喷淋灭火系统,并开展实体火灾试验。测试电动自行车在3种工况下的火灾温度,包括正常停放中起火、交界域处停放起火以及强风和喷头堵塞工况下起火,验证了水系泡沫喷淋灭火系统扑救电动自行车火灾的可靠性,获取了喷头工作压力、车棚顶部及车身温度、车辆周围热流密度等关键参数,为电动自行车充电车棚的防火设计和标准制定提供技术支撑。

Aiming at the fire problem of electric bicycle charging shed,this paper developed a special water foam sprinkler system,and carried out a physical fire test.Test the fire temperature of electric bicycle under three working conditions,including the fire during normal parking,the fire during parking at the boarder,and the fire under strong wind and nozzle blockage,verify the reliability of water foam sprinkler system in fighting electric bicycle fire,obtain the key parameters such as nozzle working pressure,shed top and body temperature,and heat flow density around the vehicle,and provide technical support for the fire protection design and standard formulation of electric bicycle charging shed.
