Smoke-eliminating and fire-extinguishing device for fire fighting

Abstract

The invention relates to the technical field for fire fighting, and particularly discloses a smoke-eliminating and fire extinguishing device for fire fighting. The smoke-eliminating and fire extinguishing device for fire fighting comprises a bottom plate and a telescopic rod, a water tank is fixedly installed on the bottom plate, the top of the water tank is connected with the telescopic rod and aconnecting rod through a rotating shaft, the air inlet end of an air pump communicates with an gas hose, the bottom of the water tank communicates with a water hose, the water hose and the gas hose penetrate through the hollow connecting rod and the telescopic rod and communicate with a smoke-eliminating and fire-extinguishing cover arranged at the end of the telescopic rod, the inner part of theside wall of the smoke-eliminating and fire-extinguishing cover is hollow and communicates with a liquid spraying nozzle arranged in the inner part of the smoke-eliminating and fire-extinguishing cover, the smoke-eliminating and fire-extinguishing cover communicates with the gas hose, the hollow part of in the inner part of the side wall of the smoke-eliminating and fire-extinguishing cover communicates with the water hose; and a driving part is fixedly mounted at a position, at the top of the water tank, below the connecting rod, the driving part is connected with a rotating wheel, and the rotating wheel is provided with a nesting roller which is nested in the inner part of a nesting groove in the lower surface of the connecting rod. The smoke-eliminating and fire extinguishing device for fire fighting has the advantages of simple structure, wide fire extinguishing range, strong applicability, good fire extinguishing and smoke eliminating effects and convenience in popularization andimplementation.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to a smoke and fire extinguishing device for fire fighting. Background technique [0002] Fire prevention is the elimination of disasters, and it is also a general term for preventing and solving the man-made, natural and accidental disasters that people encounter in the process of life, work and study. After a fire breaks out, thick smoke will be produced. Stop immediately when encountering thick smoke. Never try to get out of the smoke and crawl in a low posture in the thick smoke. Due to the rise of hot air, a large amount of dense smoke will float on the upper layer. Therefore, there should be air in the place below 30 cm from the ground in the fire. Therefore, try to crawl in a low posture and keep your head Get as close to the ground as possible. Escaping from dense smoke, if people do not protect themselves properly, they will easily inhale the dense smoke into the bo...

AI Technical Summary

Problems solved by technology

The device cannot eliminate smoke and fire at the same point at the same time, and a large amount of smoke will be generated during the fire extinguishing process, which will easily cause pollution
