Wind driven generator

The invention relates to a wind driven generator which comprises a generator and a fan body, and the generator comprises a generator shaft; the fan main body is connected with a generator shaft, and the fan main body is provided with an inflatable chamber which can be closed; when the air inflation cavity is filled with air, the fan body can be unfolded into a preset shape; the unfolded fan body rotates around the axis of the generator shaft under the action of wind power so as to drive the generator shaft to rotate. By means of the structure, when wind energy is converted into electric energy for power generation, a certain buffering effect is achieved, the risk that the fan body hits birds, aircrafts and the like in the rotating process can be reduced, meanwhile, huge damage to surrounding organisms and the environment due to blade breakage in extreme weather with the too large wind power level is reduced, and the service life of the fan body is prolonged. The safety of the wind driven generator in the oper
