The dial 4, the transverse knob 6, the vertical knob 7, the laser generator 11 and the total reflection prism 12 are positioned in the same vertical plane of the aluminum alloy shell 2; the vertical knob 7, the laser generator 11 and the total reflection prism 12 are positioned in the horizontal plane of the same height of the aluminum alloy shell 2; the axes of the dial 4 and the transverse knob 6 are coincident. The vertical knob 7 is mounted on the transverse knob 6. The total reflection prism 12 is fixedly arranged on the vertical knob 7.
The transverse knob 6 can transversely rotate relative to the aluminum alloy shell 2; the vertical knob 7 can vertically rotate relative to the transverse knob 6; the total reflection prism 12 can rotate in both the transverse and vertical directions.
The laser beam generated by the laser generator 11 is reflected by the total reflection prism 12 and then is emitted to a datum point on the top of the cabin through a window of the aluminum alloy shell 2; the laser beam generated by the laser generator 11 can swing transversely and vertically along with the rotation of the total reflection prism 12 after being reflected by the total reflection prism 12.
The working principle of the invention is as follows:
first, the device aluminum alloy housing 2 and the bottom plate 13 are connected by screw threads, and the wind vane 9 is clamped on the symmetrical inclined surface groove of the housing. And then the position of the wind vane 9 is adjusted up and down, and the direction of the wind vane 9 is rotated, so that the zero pointer 3 is aligned with the zero scale mark on the wind vane 9. At this time, the zero pointer 3 points to coincide with the center plane of the wind vane 9, and the zero pointer 3 points to be the zero degree direction of the wind vane 9.
And the position of the total reflection prism 12 is adjusted, the vertical knob 7 and the horizontal knob 6 are rotated to enable the scale pointer 5 to reach the zero position of the dial 4, at the moment, the included angle between the reflecting surface of the total reflection prism 12 and the laser beam is 45 degrees, and the emergent light of the laser beam reflected by the prism is the same as the zero-degree direction of the wind vane 9.

On the plane of the nacelle roof, a point is selected along the center line of the nacelle roof from the device L, and is marked as a datum point, and the datum point is separated from the center line L1. At this time, the line between the reflection point of the total reflection prism 12 and the reference point is parallel to the center line of the wind turbine, which can be regarded as the wind direction of the wind turbine.
At this time, the scale pointer 5 starts to adjust from the zero scale, and when the laser point formed by the laser beam on the nacelle roof is overlapped with the reference point, the direct deviation value of the scale pointed by the scale pointer 5 and the zero scale is the zero deviation of the wind vane 9. Readjusting the scale pointer 5 to point to zero scale, and loosening the wind vane 9 to fix the nut; rotating the wind vane 9 to enable the laser point to coincide with the datum point; and (5) fastening a wind vane 9 mounting nut to finish the installation and calibration of the wind vane 9.
