[0002] A forest fire extinguishing bomb is a special fire extinguishing tool for forest fires. A forest fire extinguishing bomb usually consists of a bomb body, a fire extinguishing agent, a fuse, a detonating device, etc. When the forest fire extinguishing bomb is launched or thrown into the fire scene, the fuse will be triggered under certain conditions, and the detonating device will quickly release the fire extinguishing agent in the bomb body. The fire extinguishing agent forms a strong impact force and diffusion force at the moment of explosion, which can quickly cover a large area of the fire area. At the same time, the fire extinguishing agent effectively inhibits the spread of the fire by absorbing heat, reducing temperature, isolating oxygen, etc., achieving the purpose of extinguishing the fire. The forest fire extinguishing bomb can be remotely launched to the fire scene through equipment such as a launcher, avoiding the danger of firefighters getting close to the fire source and improving the safety of fire extinguishing.
