Embodiment Construction

[0016] When the present invention was implemented, its main structure included a sand mining machine 1, a sand conveying mechanism 2, a vibrating filter mechanism 3, a sand uniform distribution mechanism 4, a Venturi tube 5, a gas guide pipe 6 and a jet gas turbine 7; sand and dust The fire extinguishing medium is taken from the fire extinguishing site and collected by the sand excavator 1. The collected sand, gravel and dust are separated from other impurities by the sand conveying mechanism 2, and then the sand, gravel and dust are transported to the vibrating filter mechanism 3 , the vibrating filtration process screens out the sandstone and dust that allow the particle size to be supplied to the sand uniform distribution mechanism 4 of the fire extinguisher, and the sandstone is evenly distributed radially on the outside of the Venturi tube 5 by this mechanism. The pressure gas used as the driving force of the fire extinguisher sand is generated by the gas turbine 7, and th...

Abstract

The invention is concerned with gas sand-gravel fire extinguishing system for forest and grassland with sand-gravel and dust. It relates to sand mining machine, sand transportation framework, vibration filtration framework, sand distributing framework, venturi tube, gas leading tube and air injection gas turbine. The sand mining machine is at the bottom of the whole equipment, while working, it connects with the earth and the spade blade mines sand and dust by deadweight or the power of spring. The sand transportation framework is in type of chain or spire, and its front part connects with leading shell to the mining machine, and its back part connects with vibration filtration framework. The two ends of venturi tube is expanding and the middle of it is contracted with some radial holes at the throat, its lumen connects with gas leading tube and outside cavity connects with sand distributing framework. This invention continues to work with well effect and high power.

Description

Technical field: [0001] The invention relates to a device for mechanically extinguishing fires in forests and grasslands using sand and dust as the medium, in particular to a gas-fired sand and gravel fire extinguishing device. Background technique: [0002] At present, forest and grassland fires occur from time to time, which has brought great harm to the living environment of human beings and animals. At present, the fire fighting methods for forests and grasslands at home and abroad include aerial sprinkler, fire escape method, personnel battering method, and water dragon spraying method. And high-pressure wind fire extinguishing method, etc. The fire escape method is a passive fire extinguishing method; the water wheel spraying method not only has problems such as difficulty in carrying water sources and limited vehicle travel; People are close to the fire source, and there is also the problem of high labor intensity and high risk; in addition, manual fire extinguishing...
