Superfine dry powder extinguishing agent and explosive combined cooperative fire extinguishing warhead for aerial bomb

Abstract

The invention discloses a superfine dry powder extinguishing agent and explosive combined cooperative fire extinguishing warhead for an aerial bomb, and belongs to the technical field of forest fire extinguishing. The superfine dry powder extinguishing agent and explosive combined cooperative fire extinguishing warhead comprises a warhead shell, a preset sleeve, a superfine dry powder extinguishing agent, a main explosive and a head plug screw. The preset sleeve is screwed at a thread at the bottom of the warhead shell; then, the extinguishing agent is filled in a cavity formed by an inner cavity of the warhead shell and the preset sleeve; the filling density of the extinguishing agent reaches a preset value through a vibration filling mode; then, the head plug screw is used for fixing theextinguishing agent in the warhead shell to form an extinguishing agent cabin section; and the main explosive is pressed as a columnar body. The superfine dry powder extinguishing agent and explosivecombined cooperative fire extinguishing warhead combines two fire extinguishing modes of a shock wave burst big fire generated by explosion of the main explosive with a superfine dry powder extinguishing agent covering suffocation small fire, achieves such effects as quick extinguishing of forest crown fire and suffocation small fire and inhibition of dead fire after-combustion, and has such advantages as simple operation, safety, reliability and high fire extinguishing efficiency.

Description

technical field [0001] The invention relates to a combined superfine dry powder fire extinguishing agent for aerial bombs and explosives for synergistic fire extinguishing warhead, which belongs to the technical field of forest fire extinguishing. Background technique [0002] As one of the most important ecological resources on earth, forests are of great importance to human society. The frequent forest fires are threatening the safety of forest resources all the time. Especially in recent years, climate change and extreme high temperature weather have occurred frequently, coupled with population expansion and accelerated industrialization, the security situation of forest resources is not optimistic. Therefore, it is of great significance to conduct research on methods and equipment for quickly and effectively extinguishing forest fires. [0003] The main deficiency of the current airborne fire extinguishing equipment is the poor effect of aerial spraying fire extinguish...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the existing fire extinguishing warhead has poor effect of high-altitude spray fire extinguishing, it is difficult to suppress the fire head, suppress the spread of fire, and cannot quickly and efficiently extinguish forest fires such as canopy fires, the purpose of the present invention is to provide an aviation The combination of superfine dry powder fire extinguishing agent and explosives for bombs cooperates with the fire extinguishing warhead. The shock wave generated by the explosion of the main explosive is used to "blow up" the fire and the superfine dry powder fire extinguishing agent covers and suffocates the small fire. It not only has the ability to quickly extinguish the forest canopy. It also has the advantages of simple operation, safety and reliability, and high fire extinguishing efficiency.
