Wind driven generator blade deicing device and installation and use method

The invention provides a wind driven generator blade deicing device and an installation and use method. The wind driven generator blade deicing device comprises a plurality of air holes formed in the tail end of a fan blade, and the outer portions of the air holes and located on the surface layer of the fan blade are covered with flexible covering films; the air holes are communicated with an air supply pipeline used for supplying air, and the air supply pipeline is communicated with an air source device used for providing high-pressure air. And an exhaust pipeline is arranged on the air supply pipeline. The deicing device solves the problem that the blades of the fan are coated with ice, normal operation of a fan unit is not affected in the deicing process, automatic or remote manual deicing can be achieved, the maintenance cost is low, the deicing efficiency is high, the air consumption is small, the requirement for 3000 times of deicing operation can be met through one-time inflation of the compressed air
