Description

technical field [0001] The invention relates to a fully automatic dry powder fire extinguishing device for fire fighting, in particular to a fire extinguishing device for automobile engine compartments and key parts of fixed places, belonging to the field of emergency rescue and fire fighting equipment, in particular to a fully automatic dry powder fire extinguishing device. Background technique [0002] At present, the number of automobiles is increasing, and fire accidents occur frequently, especially the phenomenon of mass deaths and injuries of large buses. This has attracted great attention from relevant government departments. , the safety and reliability of the fire extinguishing device itself and the quickness of starting are even more important. At present, the engine compartment fire extinguishing devices on the market mainly include aerosol automatic fire extinguishing devices and hanging explosive fire extinguishing bombs. Both of these fire extinguishing devices...

AI Technical Summary

Problems solved by technology

At present, the engine compartment fire extinguishing devices on the market mainly include aerosol automatic fire extinguishing devices and hanging explosive fire extinguishing bombs. Both of these fire extinguishing devices put the main shell containing dry powder into the engine compartment. Due to the limitation of the space in the engine compartment, , taxis, trucks and other medium and small vehicles generally have no installation position, only large passenger cars can be installed, and the effect is average, only primary fire extinguishing

In addition, most of the manual work cannot detect the fire in the engine compartment in time, which delays the best time to extinguish the fire, and ultimately there is no chance of escape. There are also some automatic fire extinguishing devices that may have failed after several years of installation, but the driver does not know, and eventually loses the opportunity to extinguish the fire
