Description

Technical Field

[0001] The utility model relates to the field of wind power generation, in particular to a wind vane device for a wind turbine generator. Background Art

[0002] A wind vane is a crucial piece of equipment in a wind turbine's weather station. It converts wind direction signals into electrical signals and outputs them to the wind turbine's main control system, guiding the turbine's yaw to the wind, ensuring the turbine head maintains the proper angle to the wind direction, maximizing energy and generating more electricity. Currently, wind vanes are typically fixed to the weather station's bracket via their lower base, which features a zero mark. Zeroing the wind vane is typically performed by visually inspecting the zero mark on the vane to ensure it's aligned with the wind turbine's axis. This installation method results in low zeroing accuracy and poor consistency, impacting the wind turbine's power generation efficiency. Utility Model Content
