[0002] The unmanned plane fire extinguishing ball is a new type of fire extinguishing equipment, which is carried on the unmanned plane, and the fire extinguishing ball is internally provided with fire extinguishing agent. When encountering fire, the unmanned plane can quickly fly above the fire site, and then the fire extinguishing ball is thrown to the ignition point. The response speed of this fire extinguishing mode is fast, the unmanned plane can quickly pass through complex terrain and traffic congestion area to reach the fire site, and is less limited by road conditions and other factors compared with the traditional fire truck. Furthermore, through the control system of the unmanned plane, the fire extinguishing ball can be more accurately thrown to the core area of the fire, improving the fire extinguishing efficiency. It is suitable for various fire scenes, such as forest fire. In the initial stage of fire spread, the unmanned plane carrying the fire extinguishing ball can quickly control the ignition point. The unmanned plane can also play a role in quickly and accurately extinguishing fire for some high-rise building fires that personnel cannot quickly reach.
