[0001] The utility model relates to the technical field of wind power generators, in particular to a wind direction regulating device for a wind power generator set. Background Art
[0002] A wind turbine is a generator that drives the generator by rotating the impeller through wind power. During the use of a wind turbine, when the wind direction changes, if the wind turbine cannot adjust its direction in time, it will lose wind energy and cause unnecessary losses.

The above document still has deficiencies. When in use, the wind direction is detected by the wind vane. When the wind direction changes, the wind vane rotates to change the electric control mechanism from an open state to a closed state, so that the circuit connected to the driving mechanism is connected, thereby driving the wind vane. The driving mechanism is started to make the impeller group gradually turn, and finally the rotation axis of the impeller group is parallel to the wind vane.
