In the forest fire fighting rescue, the ground fire fighting power limitation is large under the influence of the landform and the landform of the forest and traffic, the fire fighting equipment is mainly held by fire officers and soldiers to extinguish fire in a short distance, and the personal safety is difficult to guarantee.
The method is a brand new forest fire extinguishing method by adopting a long-distance or helicopter air throwing forest fire extinguishing bomb. The long-distance throwing type fire extinguishing bomb is triggered by the impact needle to fall to the ground for detonation, the fire extinguishing agent cannot be dispersed to the area of the tree crown, and the tree crown fire cannot be effectively extinguished. The helicopter is limited by the safe flying height above a fire scene, so that the fire extinguishing bomb has a larger falling speed, the existing fire extinguishing bomb mostly adopts a temperature control fuse system or a remote control fuse system to detonate the fire extinguishing bomb, the optimal detonation time is easy to miss under the influence of the reaction time of the temperature control system and the transmission time of remote signals, and the fire extinguishing bomb is detonated after passing through a tree canopy area. A small number of fire extinguishing bombs are influenced by updraft and strong crosswind in a fire scene in the falling process to cause track deviation, and then fall to a fire-free area to cause economic loss, and the comprehensive fire extinguishing performance of the forest fire extinguishing bombs is influenced.
