Adjustment device for adjusting inclination of a wind turbine

The present invention relates to an adjustment device for adjusting inclination of a wind turbine which includes a base, a blade unit including multiple blades and each blade having an adjustment unit, a detection unit connected with the blade unit so as to detect the azimuth angle of the blades relative to the axis, and a processing unit connected with the detection unit and the adjustment unit so as to drive the adjustment units to control the pre-set pitch angles of the wind turbine blades relative to the azimuth angle. The pitch angles are increased from the initial value toward positive or negative direction, or maintained the pitch angles at the first and second critical values according to the upwind or downwind status of the blades to increase the ability of automatically activated and reduce possibility of stalling, and obtain high efficiency of power generation.
