Cluster type forest fire extinguishing bomb with multi-fuze and self-deceleration characteristics

Abstract

The invention provides a cluster type forest fire extinguishing bomb with multi-fuze and self-deceleration characteristics. The cluster type forest fire extinguishing bomb comprises a plurality of cluster type forest fire extinguishing bomb single bodies, Each cluster type forest fire extinguishing bomb single body comprises a detonating agent, a paper agent shell, a superfine dry powder extinguishing agent, a paper bomb shell, ignition fuses, a rotating shaft and an eccentric turbulence belt, wherein the detonating agent is tightly fixed to the center of the cluster type forest fire extinguishing bomb single body through the paper agent shell, the space between the paper bomb shell and the paper agent shell is filled with the superfine dry powder fire extinguishing agent, the twelve ignition fuses are evenly distributed on the paper bomb shell and fixedly connected with the detonating agent, the rotating shaft is fixed to the top end of the outer portion of the paper bomb shell, the eccentric turbulence belt is fixed to the rotating shaft and is folded and attached to the surface of the paper bomb shell, and the eccentric turbulence belt can freely rotate along with the rotating shaft and can be opened under the action of wind. The cluster type forest fire extinguishing bomb with the multi-fuze and self-deceleration characteristics has the advantages of strong maneuverability, fast response, wide coverage area, high hit accuracy, high safety and the like, realizes fast and efficient extinguishing of forest crown fire, and can be flexibly applied to fire in a closed space.

Description

technical field [0001] The invention belongs to a fire-fighting fire-extinguishing device, and in particular relates to a cluster type forest fire-extinguishing bomb with the characteristics of multiple fuzes and self-deceleration. Background technique [0002] Forest fires occur in the forest open system, and have the characteristics of strong suddenness, rapid fire spread, large fire damage area, and difficulty in fighting and rescue, causing heavy losses and serious harm to forest resources, ecological environment, and human life. In forest fire fighting and rescue, due to the impact of forest topography and traffic, the ground firefighting forces are relatively limited. They mainly rely on firefighters and soldiers to extinguish fires at close range with hand-held firefighting equipment, and personal safety is difficult to guarantee. [0003] It is a brand-new forest fire extinguishing method to adopt long-distance or helicopter to drop forest fire extinguishing bombs in...

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
