A forest aviation fire extinguishing bomb launched by gravity and its application method

Abstract

The invention discloses a forest aviation fire extinguishing bomb that is put in by gravity and a use method thereof, and belongs to the field of fire extinguishing bomb technical design. Grain column, sealing ring, rear end cover, fastening screw, empennage. The fire extinguishing bomb is mounted by the forest aviation firefighting helicopter and dropped at a certain height above the fire scene. When the distance between the fire extinguishing bomb and the ground reaches the preset explosion height, the fuze will ignite and detonate the fire extinguishing bomb. Under the action of the center charge and the tail charge , The fire extinguishing agent is evenly and quickly sprinkled on the surface of the burning object to achieve the purpose of fire extinguishing. Forest aviation fire extinguishing bombs are launched by gravity, which avoids the problem of low hit accuracy of existing fire extinguishing bombs; through the charge structure and large fire extinguishing agent filling ratio, it effectively solves the problems of small coverage area of ​​current fire extinguishing bombs and uneven distribution of fire extinguishing agents. The invention can be used not only for fighting forest fires, but also for fighting grassland fires.

Description

technical field [0001] The invention relates to the technical field of fire-extinguishing bombs, in particular to a forest aviation fire-extinguishing bomb dropped 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 statistics of the National Bureau of Statistics in the past 10 years, forest fires cause damage to tens of thousands of hectares of forest resources in my country every year, with direct economic losses of hundreds of millions of yuan, and indirect ecological losses are incalculable. Although the number of major forest fires accounts for less than 1% of my country's forest fires, they are the main cause of casualties among forest firefighters in my country. Conventional manual fire-fighting measures are difficult to effectively extinguish them, and aerial water hoisting is often required to put out...

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.
