一种电动汽车火灾扑救装置的灭火效能研究

Research on fire extinguishing efficiency of a fire extinguishing device for electric vehicles

为了研究电动汽车火灾快速扑救,笔者结合实际工作经验,设计了一种电动汽车火灾扑救装置,通过消防车出不同水压,测试扑救装置性能;选取电动汽车进行燃烧试验,观察扑救装置扑救电动汽车火灾的效果。结果表明:在消防车出水0.5 MPa和0.7 MPa条件下,电动汽车火灾扑救装置出水流量和冲击力明显优于多功能水枪;燃烧实战测试中,该扑救装置能对燃烧车辆进行有效的降温控火。

In order to study the rapid extinguishing of electric vehicle fires,the author designed an electric vehicle fire extinguishing device based on practical work experience.The performance of the extinguishing device was tested by different water pressures of the fire truck.Select electric vehicles for combustion tests and observe the effectiveness of the firefighting device in extinguishing electric vehicles.The results show that the electric vehicle fire extinguishing device has significantly better water flow rate and impact force than the multifunctional water gun under the conditions of 0.5 MPa and 0.7 MPa water output from the fire truck.In the actual combustion test,the firefighting device effectively cools down and controls the fire of the burning vehicle.
