In the figure: 1. the tower comprises a tower rod, 2, a machine body, 3, a motor, 4, a transmission mechanism, 5, an annular base, 6, a wind measuring device, 7, a first half ring, 8 and a second half ring.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

A wind vane wind alignment device of a fan, as shown in figure 1, comprises a body 2, a motor 3, a transmission mechanism 4, an annular base 5, a wind measuring device 6 and a control chip. The body 2 is mounted on the tower 1 by bearings. A transmission mechanism 4 is arranged between the motor 3 and the tower pole 1, and the motor 3 and the transmission framework are both arranged on the machine body 2. The machine body 2 can rotate relative to the tower pole 1, and the rotation of the machine body 2 is driven by the motor 3 and the transmission mechanism 4. The annular base 5 is installed on the lateral wall of tower pole 1, and the height of annular base 5 is less than the minimum height of blade, and annular base 5 is through welding or through section of jurisdiction bolted connection tower pole 1. The ring-shaped base 5 comprises a first half ring 7 and a second half ring 8, as shown in fig. 2, one end of the first half ring 7 is hinged with one end of the second half ring 8, the other end of the first half ring 7 can be connected with the other end of the second half ring 8 through a bolt, the first half ring 7 and the second half ring 8 are buckled to form a whole circular ring, namely, the ring-shaped base 5, and the tower pole 1 is positioned in the circular ring. The wind measuring device 6 is arranged on the annular base 5, the wind measuring devices 6 are arranged on the first half ring 7 and the second half ring 8, and the wind measuring devices 6 can adopt a wind measuring instrument, a wind measuring instrument and/or a wind speed sensor or adopt a wind vane in the patent CN200920194049.
