Wind energy is used as clean energy and plays a very important role in global energy structure adjustment and transformation. However, as the capacity of a single machine of the wind turbine generator is larger and the operation time is longer and longer, various accidents are more and more, wherein the fire accidents of the wind turbine generator occupy a large proportion, but as the wind power plant is often built in a remote area, once the fire happens, the fire engine is difficult to reach the site in time. And the wind turbine generator is often installed at high altitude several tens of meters or even hundreds of meters away from the ground, so that fire is generated, and the effect of extinguishing fire on the ground is difficult to take. Therefore, the loss is great when the wind turbine generator is in a fire accident.
