A fire water gun with water cutting function

Abstract

Disclosed is a fire-fighting lance with a water cutting function. The fire-fighting lance with the water cutting function comprises a conveying water pipe, an extinguishment lance spray nozzle, a jet cutting lance head and an ultrahigh-pressure water generator. The output end of the conveying water pipe is connected with a water conveying valve body, the front end of the water conveying valve body is connected with an output water pipe through a pipe connector, and an external-thread pipe head is arranged at the front end of the output water pipe, passes through a through hole of a fixing plate arranged on the bottom side of a fixing sleeve and is connected with an internal-thread pipe opening of the extinguishment lance spray nozzle in a threaded mode. A sealing separating plate is welded in the middle of the fixing sleeve, a sealed high-pressure cavity is formed in the portion, located on the top of the sealing separating plate, of the fixing sleeve, and the front end of the high-pressure cavity is communicated with the jet cutting lance head. Water is sprayed from the extinguishment lance spray nozzle to conduct fire extinguishment, and therefore the firmness and the stability of utilization of the jet cutting lance head are enhanced; and water is sprayed out of the jet cutting lance head, glass, boards and other things existing in the extinguishment lance spray nozzle fire extinguishment process are cut and broken, and therefore the extinguishment lance spray nozzle can conveniently spray water to the portion which is on fire, and the efficiency of fire rescue is improved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting water gun with water cutting function. Background technique [0002] The fire water gun is a device used to spray fire extinguishing substances in the firefighting process, and it is the most basic firefighting equipment in the field of firefighting. The use of the existing fire-fighting nozzle can realize the on-off of the fire-extinguishing substance by turning the valve handle of the ball valve switch. After the ball-valve switch is opened, the fire-extinguishing substance is sprayed from the fire-fighting nozzle to the fire site for fire extinguishing. However, in the actual fire extinguishing operation, often due to the obstruction of glass, wooden boards and other objects on the building, the water sprayed from the fire water gun cannot reach the fire site directly, and firefighters need to risk their lives to carry out fire fighting with fir...

AI Technical Summary

Problems solved by technology

However, in the actual fire extinguishing operation, often due to the obstruction of glass, wooden boards and other objects on the building, the water sprayed from the fire water gun cannot reach the fire site directly, and firefighters need to risk their lives to carry out fire fighting with fire axes and other equipment. Spray water from the fire hose to the fire site

During demolition, firefighters are easily injured by glass fragments or wood debris and falling fire objects, which also reduces the fire extinguishing efficiency
