Shock-wave sand stone extinguishing cannon

Abstract

The invention is concerned with shock sand-grave fire extinguishing cannon, a fire extinguishing system for forest and grassland with sand-gravel and dust. It relates to compressed gas supply, compressed gas cut-off valve, shock tube, separating valve of shock tube sand-grave cannon, sand-grave cannon, sand-grave, sand-grave transportation framework and sand-grove mining machine. The tube type ofshock tube is separated into high press cavity and low press cavity by on-off valve of film. The compressed gas supply is made up of air compressor and gas storage connecting with the tube of shock tube. The separating valve of shock tube sand-grave cannon connects with shock tube and sand-grove cannon. The sand-grave transportation framework is in type of chain or spire, and its front part connects with vibration filtration framework to sand mining machine, and its back part connects with the sand-filling hole to sand-grave cannon. The compressed gas supply connects with shock tube by compressed gas cut-off valve. The material to put out a fire is familiar and the invention has high efficiency and effect, long cannon-shot to save energy sources.

Description

Technical field: [0001] The invention relates to an equipment device that uses sand and gravel and soil dust as a medium for long-distance fire extinguishing in forests and grasslands, etc., in particular to a shock wave sand and gravel fire extinguisher. Background technique: [0002] Existing forest and grassland fire extinguishing methods, in addition to aerial sprinkling, the ground generally uses fire-fighting channel method, personnel fighting method, water jet extinguishing method and high-pressure wind fire extinguishing method. The fire passage method is a passive fire extinguishing method. The water jet extinguishing method not only has the problems of difficulty in carrying water sources and limited vehicle driving; the personnel fighting method has low efficiency, high labor intensity and high risk; wind fire extinguishing method also requires personnel Close to the fire source, there are also the problems of high labor intensity and high risk. In addition, the latter...

AI Technical Summary

Problems solved by technology

The fire escape method is a passive fire extinguishing method. The water dragon spraying method not only has the problems of difficulty in carrying water sources and restricted vehicles; Close to the fire source, there are also the problems of high labor intensity and high risk. In addition, the latter two fire extinguishing methods are difficult to be effective and quickly extinguish large-area fires and high-altitude fires.
