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.

Embodiment Construction

[0008] The implementation main structure of the present invention comprises a compressed gas source 1, a compressed gas shut-off valve 2, a shock tube 3, a shock tube gravel cannon separation valve 4, a gravel cannon 5, gravel 6, a gravel conveying mechanism 7 and a gravel Excavator 8 becomes a coordinated integrated long-distance fire extinguishing gun through conventional technical process combination assembly.

[0009] The shock tube 3 mentioned in the embodiment of the present invention is the power of the gravel gun 5, it is a tubular structure with the same diameter, and is divided into a high-pressure chamber and a low-pressure chamber, between the high-pressure chamber and the low-pressure chamber is controlled by a transient switch valve or Diaphragm separated. The low-pressure chamber is filled with normal-pressure medium, and the high-pressure chamber is filled with high-pressure air. The principle of the shock tube 3 is to use higher gas pressure to induce the sho...

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 of shock 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 a device for long-distance fire extinguishing in forests and grasslands using sand and dust as the medium, in particular to a shock wave sand and stone fire extinguishing cannon. Background technique: [0002] Existing forest, prairie fire extinguishing mode, except aerial sprinkling type, the ground generally adopts fire escape method, personnel battering method, water dragon spraying method and high-pressure wind fire extinguishing method etc. 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 extinguished for large-area fires and high-altitude fires. Invention content: [0003] The purpose of the pres...
