Abstract

The invention discloses a main-sub type airborne fire extinguishing bomb. A window breaking assembly is mounted on the end face of the front end of a main body of the fire extinguishing bomb through afront connecting cover, a rear connecting cover is mounted on the end face of the rear end of the main body of the fire extinguishing bomb, and a front connector of a micro rocket engine is mounted in a mounting hole on the outer end face of the rear connecting cover. A sub fire extinguishing bomb filling cabin is located in the main body of the fire extinguishing bomb, and each sub fire extinguishing bomb is respectively fixed in the filling cabin. A temperature control switch of each sub fire extinguishing bomb faces one end of the micro rocket engine. The firing speed of the fire extinguishing bomb is higher than 20m/s, the fire extinguishing area can reach 30m<2>, next firing operation can be carried out by hanging the fire extinguishing bomb on an aerial platform again after the firing is finished, the preparation time is less than ten minutes, and a group of batteries are enough for multiple firing. The main-sub type airborne fire extinguishing bomb has the characteristics of simple structure, convenient operation and light weight, can avoid secondary damage to indoor people caused by fragments splashed after fragmentation, and has good safety.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing bombs, and in particular relates to a mother-in-two type airborne fire extinguishing bomb. Background technique [0002] With the rapid development of industrialization and urbanization in our country, the number of high-rise buildings has increased sharply. Once a fire breaks out, its danger and fire extinguishing difficulty are far greater than those of ordinary low-rise buildings. The traditional water gun fire extinguishing method is lacking in efficiency and safety. There is a limit on the height of fire extinguishing. In recent years, some fire extinguishing devices that launch fire extinguishing bombs have appeared, including missile fire extinguishing fire trucks, fire extinguishing drones, etc., and the UAV platform can achieve higher launch heights, and the cost is also lower. With a huge market prospect, the unmanned aerial vehicle platform and fire extinguishing bomb launch ...
