The revolution α direction of the vane plate 50 is the same as the rotation β direction of the vane plate 50 relative to the earth, the same revolution β 0 direction of the vane plate 50 as the rotation β direction of the vane plate 50 means that both the revolution α and the rotation β rotate counterclockwise or clockwise when looking down on the windmill, wherein the rotation β direction is the rotation β direction relative to the earth, and the rotation β relative to the earth is equal to the revolution α minus the rotation angle of the rotation β relative to the hinge shaft 51, and the rotation direction of the rotation α relative to the hinge shaft 51 is opposite to the revolution α direction.
When the plane where the axis of the hinge shaft 51 and the axis of the rotating shaft 30 are located is parallel to the wind direction, the included angle between the surface of the wind vane plate 50 and the wind direction is 45 degrees.
