AI Technical Summary
In existing technologies, maintenance personnel lack clear installation references when replacing wind vanes, resulting in inaccurate installation positions that affect wind turbine yaw control and power generation efficiency.
A wind vane installation positioning indicator device for wind turbine generator sets was designed, comprising a fixed base, a locking mechanism, and an indicating mechanism. It uses a mechanical pointer to point to the 0° or 180° position, providing an accurate installation reference.
The mechanical pointer ensures the accuracy of the wind vane installation, avoids installation deviations, and improves the precision of wind turbine yaw control and power generation efficiency.
