High-expansion foam type and explosive combination synergistic firefighting part for aerial bomb

Abstract

The invention discloses a high-expansion foam type and explosive combination synergistic firefighting part for an aerial bomb, and belongs to the technical field of forest fire fighting. The high-expansion foam type and explosive combination synergistic firefighting part for the aerial bomb comprises a fighting part shell, a high-expansion foam extinguishing agent, a primary explosive, a sealing gasket and a head plug screw. According to the high-expansion foam type and explosive combination synergistic firefighting part for the aerial bomb provided by the invention, through the combination of'scattering' a big fire through a shock wave produced after the primary explosive is exploded, and isolating a soft fire from air through foams adhered onto combustible materials, a fire fighting manner of smothering and cooling a flame is realized, so that the high-expansion foam type and explosive combination synergistic firefighting part for the aerial bomb has the efficacies on quickly extinguishing a forest crown fire, smothering and cooling the soft fire, inhibiting resurgence and the like. According to the high-expansion foam type and explosive combination synergistic firefighting partfor the aerial bomb provided by the invention, a high-expansion foam extinguishing agent is selected, and high-expansion foams continuously ejected after foaming are quickly adhered onto the surfacesof the scattered fire and the soft fire through a covering way, so that the flame and air are isolated, the temperature is reduced at the same time, the combustion condition is destroyed, the continuous combustion of the forest scattered fire and the soft fire can be weakened, and the after-combustion of remaining fire can be further inhibited. The high-expansion foam type and explosive combination synergistic firefighting part for the aerial bomb provided by the invention has the advantages of simplicity in operation, cleanliness, environment protection, safety, reliability, high firefighting efficiency and the like.

Description

technical field [0001] The invention relates to a high-expansion foam-type combined with explosives cooperative fire extinguishing warhead for aerial bombs, 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 extinguishing: after a disaster oc...

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 tree crown fires, the purpose of the present invention is to provide an aerial vehicle. The bomb uses a combination of high-expansion foam and explosives to cooperate with the fire extinguishing warhead. The shock wave generated after the explosion of the main explosive is used to "blow up" the fire and the foam adhered to the combustible material to isolate the small fire from the air to suffocate and cool the fire. The combination of methods not only has the effects of quickly extinguishing forest canopy fires, suffocating and cooling small fires, and inhibiting resurgence, but also has the advantages of simple operation, clean and environmentally friendly, safe and reliable, and high fire extinguishing efficiency.
