Abstract
Description
Technical Field
[0001] The invention relates to a turbojet fire extinguisher, in particular to a turbojet fire extinguisher with a telescopic connecting rod. Background Art
[0002] Wind-powered fire extinguishers currently play an important role in forest fire prevention, and turbojet fire extinguishers are an upgrade of them. However, due to the defects in the principle of turbojet fire extinguishers, the wind power generated by its turbojet is relatively strong, and the nozzle will produce overheated air, so that the nozzle cannot be used like ordinary wind-powered fire extinguishers. The long nozzle is used to guide and discharge air, so the nozzle of the turbojet fire extinguisher is much shorter than that of ordinary wind-powered fire extinguishers. When performing wind-powered fire fighting, either the distance between the nozzle and the fire source becomes longer, which greatly affects the effect of fire fighting and also leads to a lot of energy waste, or the firefighters hold the short-tube turbojet fire fighting equipment very close to the fire source, which requires firefighters to get close to the fire source when extinguishing the fire, resulting in the fire source being closer to the firefighters, which is easy to cause danger. Summary of the invention
