Cluster Forest Fire Extinguishing Bomb with Multiple Fuzes and Self-Deceleration

Abstract

The invention provides a cluster type forest fire extinguishing bomb with the characteristics of multiple fuzes and self-deceleration, comprising several cluster type forest fire extinguishing bomb monomers; Superfine dry powder fire extinguishing agent, paper cartridge case, ignition fuze, rotating shaft, eccentric spoiler; the detonating agent is tightly fixed in the center of the cluster forest fire extinguishing bomb through the paper agent case, and the superfine dry powder fire extinguishing agent is filled in the paper cartridge case and the single center of the cluster forest fire extinguishing bomb. Between the paper cartridges, 12 ignition fuzes are evenly distributed on the paper cartridges and are fixedly connected to the detonating cartridges. The rotating shaft is fixed on the outer top of the paper cartridge, and the eccentric spoiler is fixed on the rotating shaft and is folded and attached to the paper. The surface of the shell can be freely rotated with the rotating shaft, and the eccentric spoiler can be opened by the wind. The invention has the characteristics of strong maneuverability, fast response, wide coverage, high hit accuracy and high safety, realizes rapid and efficient forest canopy fire, and can also be flexibly used for confined space fire.

Description

technical field [0001] The invention of the invention belongs to a fire extinguishing device, in particular to a cluster type forest fire extinguishing bomb with the characteristics of multiple fuzes and self-deceleration. Background technique [0002] Forest fires occur in open forest systems, and have the characteristics of strong suddenness, rapid fire spread, large fire damage area, and difficulty in extinguishing and rescue. They cause heavy losses and serious harm to forest resources, ecological environment and human life. In forest fire fighting and rescue, due to the influence of forest topography and traffic, the ground firefighting power is relatively limited, mainly relying on fire officers and soldiers holding firefighting equipment to put out fires at close range, and personal safety is difficult to guarantee. [0003] The use of long-distance or aerial-dropping forest fire bombs is a new method of forest fire fighting. Among them, the long-distance throwing fi...

AI Technical Summary

Problems solved by technology

Among them, the long-distance throwing fire extinguishing bombs are all detonated on the ground by the impact needle excitation method, and the fire extinguishing agent cannot be diffused to the crown area, which cannot effectively extinguish the crown fire.

Helicopters are limited by the safe flying height above the fire field, resulting in a relatively high falling speed of the fire extinguishing bombs. However, most of the existing fire extinguishing bombs use a temperature-controlled fuze system or a remote control fuze system to detonate the fire-extinguishing bombs, which are affected by the response time of the temperature control system and the transmission time of remote signals. , it is easy to miss the best detonation time, which will cause the fire extinguishing bomb to detonate after passing through the canopy area

A small number of fire extinguishing bombs are affected by the updraft and strong crosswind in the fire field during the falling process, causing the track to deviate, and then falling to the fire-free area, causing economic losses and affecting the comprehensive fire extinguishing performance of forest fire extinguishing bombs
