Movable pulse air pressure spraying water gun and fire extinguishing method

Abstract

The invention provides a movable pulse air pressure spraying water gun and a fire extinguishing method. The movable pulse air pressure spraying water gun comprises a pulse gun, a high-pressure water pump which supplies water to the pulse gun through a water conveying hose, and a gas cylinder which supplies to the pulse gun through a high-pressure gas conveying hose; a water inlet switch is mountedon the water conveying hose; a pressure reducer is mounted on the high-pressure gas conveying hose; the pulse gun is provided with an inflator and a launch canister; an air valve is installed betweenthe inflator and the launch canister and controlled by a trigger structure which is arranged at the bottom of the inflator to be opened or closed; the high-pressure gas conveying hose is connected tothe side wall of the inflator; the water conveying hose is connected to the side wall of the launch canister; an atomizing nozzle is detachably mounted at the front end of the launch canister, the launch canister is further used for mounting a fire extinguishing bomb and an incendiary tool; and an arc-shaped airflow groove is formed in a valve seat of the air valve. The movable pulse air pressurespraying water gun has the functions of water mist fire extinguishing, fire extinguishing bomb fire extinguishing and ignition; and the airflow groove in the valve seat of the air valve is designed into an arc-shaped surface, so that the pressure of the movable pulse air pressure spraying water gun is improved.

Description

technical field [0001] The application relates to a mobile pulse air pressure spray water gun and a fire extinguishing method. Background technique [0002] Due to the characteristics and laws of forest fires, it is very difficult for human beings to use hand tools to extinguish fires in the face of large-scale forest fires. With the development of society and the continuous progress of science and technology, technologies such as meteorology, remote sensing, computer, laser, communication and aerospace are booming, and chemical and biological technologies are constantly updated, coupled with the application of modern scientific management, providing advanced forest fire fighting. means and technical conditions. For example, the application of infrared, radar, laser, satellite remote sensing and other technical means to monitor forest fires in real time, the application of new technologies such as water fire extinguishing, aviation fire extinguishing, chemical fire extingui...

AI Technical Summary

Problems solved by technology

For example, the application of infrared, radar, laser, satellite remote sensing and other technical means to monitor forest fires in real time, the application of new technologies such as water fire extinguishing, aviation fire extinguishing, chemical fire extinguishing, artificial rain enhancement and computer forest fire management systems, etc., in order to improve the ability to control forest fires, Minimizing the loss of forest fires has provided guarantees; but there is still a need for more effective and safer fire extinguishing devices and methods to ensure the safety of firefighters

[0003] The pulse air pressure spray water gun uses water mist to extinguish the fire, and uses high-pressure gas to spray water from the port of the mobile pulse air pressure spray water gun. It has the function of reducing dust and exhausting smoke, so it is widely used in fire fighting of forest fires; but the existing pulse air pressure spray gun has a single function, has the disadvantages of unstable pressure, too long stroke of the water inlet switch, and inconvenient operation.
