Forest aviation fire extinguishing bomb thrown through gravity and using method

Abstract

The invention discloses a forest aviation fire extinguishing bomb thrown through gravity and a using method, and belongs to the field of technical design of fire extinguishing bombs. The forest aviation fire extinguishing bomb comprises a fuse, a central charging pipe, a central grain, a fire extinguishing agent, a fire extinguishing bomb shell, a tail grain, a sealing ring, a tail end cover, a fastening screw and a tail fin. The fire extinguishing bomb is mounted by a forest aviation fire-fighting helicopter and is thrown at a certain height above a fire scene, when a distance between the fire extinguishing bomb and the ground reaches a preset explosion height, the fire extinguishing bomb is ignited and detonated by firing the fuse, the fire extinguishing agent is uniformly and quickly thrown to the surface of comburent under the action of central charging and tail charging, so that the fire extinguishing purpose is achieved. The forest aviation fire extinguishing bomb is thrown through gravity, and the problem that an existing fire extinguishing bomb is low in hit precision is solved. By means of the charging structure and a large fire extinguishing agent filling ratio, the problems that an existing fire extinguishing bomb is small in coverage area, uneven in fire extinguishing agent distribution and the like are effectively solved. The fire extinguishing bomb can be used for forest fire extinguishing and grassland fire extinguishing.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing bombs, in particular to a forest aviation fire extinguishing bomb launched by gravity and a method for using the same. Background technique [0002] Forest fires are sudden, destructive and dangerous, and are one of the most frequent and serious natural disasters in the world. According to the statistical data of the National Bureau of Statistics in the past 10 years, forest fires cause damage to tens of thousands of hectares of forestry resources in my country every year, with direct economic losses of hundreds of millions of yuan and indirect ecological losses that are difficult to estimate. Although the number of severe forest fires accounts for less than 1% of forest fires in my country, it is the main cause of casualties of forest firefighters in my country. It is difficult to effectively extinguish them by conventional manual fire extinguishing measures, and it is often necessary ...

AI Technical Summary

Problems solved by technology

[0006] In view of the above analysis, the present invention aims to provide a forest aviation fire extinguishing bomb and its use method through gravity delivery, in order to solve the problem of low filling ratio of fire extinguishing agent, small coverage area, uneven distribution of fire extinguishing agent, and problems caused by existing fire extinguishing bomb products. The effect of the updraft on the fire scene is difficult to reach the surface of the burning object, and the launch accuracy is not good.
