Description

Technical Field

[0001] The utility model relates to the technical field of wind vane applications, and particularly relates to an auxiliary replacement tool for a wind vane of a wind turbine generator set. Background Technique

[0002] At present, most wind turbine generator sets install and use mechanical wind vanes. During the installation process of the wind vane, the orientation of the wind vane needs to be parallel to the rotation axis of the impeller of the wind turbine generator set. After the direction indicated by the wind vane is parallel to the rotation axis of the wind wheel, the unit aligns with the wind according to the data fed back by the sensor.

[0003] In actual replacement projects, due to the lack of necessary reference objects on the top of the nacelle cover, the alignment of the main rod depends only on the visual inspection and experience judgment of the maintenance personnel, and there are usually large errors in the actual replacement process. Due to the errors in the installation process, the wind turbine generator set fails to achieve accurate wind alignment. There is an included angle between the axis of the wind wheel and the oncoming flow direction during operation, resulting in a reduction in the wind energy absorption rate and a decrease in the power generation of the unit.

[0057] A recessed portion 612, also arranged inside the clamping seat 61 and abutting against the outer wall of the fixed column 1.

[0058] With such a design, the clamping seat 61 has elasticity. When the protruding portion 611 is opened, the clamping seat 61 is sleeved on the fixed column 1, and the fixed column 1 enters and abuts against the recessed portion 612. At this time, the clamping seat 61 has a pre-clamping effect, and the position of the clamping seat 61 on the fixed column 1 is pre-stabilized.

[0059] In one embodiment, a fastening assembly is arranged on the clamping seat 61 for fastening the clamping seat 61;

[0060] The fastening assembly includes:
