Forest fires are forest fire behaviors which bring certain harm and loss to forests, forest ecosystems and human beings, and have natural disasters which are strong in outburst, large in destructiveness and difficult to dispose and rescue. Forest fires not only burn trees to directly reduce the forest area, but also seriously destroy forest structures and environments, cause the balance of a forest ecological system to be lost, reduce the forest biomass, weaken the productivity and even cause the death of people and livestock. Meanwhile, a great amount of smoke is generated by forest combustion, and the main components are carbon dioxide and water vapor, so that the air is polluted, and the human health and the survival of wildlife are harmed. Therefore, the development of forest fire extinguishing devices is very important, and the main existing forest fire extinguishing forms mainly comprise fire extinguishing water guns, pneumatic fire extinguishers, fire extinguishers and the like. The fire-extinguishing water gun mostly adopts a backpack type, takes water for fire extinguishing as a medium, and has the defects of high fire-extinguishing efficiency, limited spraying distance, incapability of approaching a fire source by manpower, large water resource requirement and the like when a forest has a serious fire; the wind power fire extinguisher rectifies and sucks external air from the protective cover, then boosts and accelerates the air and forms strong high-speed air jet flow through the fan volute and the air duct to blow out flame, but the limitation is that the height of the flame of forest fire is less than 1.5 m, the wind speed is less than 4-level, and the device is limited if a serious fire occurs; due to the fact that the fire extinguishing cannons are troublesome to transport, one cannon is controlled to be 20 square meters at most, and the fire extinguishing cannons cannot be used for extinguishing fire when mountain fire is large.
