A kind of fire extinguishing aerial bomb used for forest canopy fire

Abstract

The invention provides an extinguishing bomb for forest crown fire. The extinguishing bomb comprises a bomb body and a tail wing. The bomb body is a cavity body and comprises a sealing plug, a shearing part, a gas generating device and a fire extinguishing agent storing chamber. The sealing plug is in fit connection with a nozzle at the top end of the fire extinguishing agent storing chamber. One end of the shearing part is connected with the inner side face of the sealing plug, and the other end of the shearing part is connected with the front end of a pushing rod. The gas generating device and the fire extinguishing agent storing chamber are separated through a metal sleeve tube. The rear end of the pushing rod is connected with the front end of a combustion chamber, and the rear end of the combustion chamber is connected with a gas generator of the gas generating device. An intelligent temperature sensing control device is arranged in the tail wing and connected with the gas generator. The extinguishing bomb has the advantages of being simple in structure, convenient to assemble and the like; the extinguishing bomb is a safe extinguishing bomb, can be adaptive to long-time storage and transportation and other service treatment, and has high reliability and safety.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a safe fire extinguishing aerial bomb used for forest canopy fires. Background technique [0002] There are more than 220,000 forest fires in the world every year, and the burned forest area exceeds 6.4 million hectares, accounting for more than 0.23% of the world's forest coverage. my country's forest area is 120 million hectares, and the forest area engulfed by fires every year is 1.1 million hectares, accounting for 0.8% to 0.9% of the national forest area. Therefore, forest fire fighting has always been an important part of disaster prevention and mitigation. . [0003] Forest fires are usually divided into three types: surface fires, tree crown fires, and underground fires according to their burning objects and burning parts. Among various types of forest fires, forest fires dominated by canopy fires are the most harmful, and the existing fire fighting equipment cannot directl...

Problems solved by technology

However, due to the particularity of tree crown fires, there is no fire-fighting equipment for long-range, rapid and suppressive fire fighting, so tree crown fires often become the most important factor leading to major forest fires
