AI Technical Summary
The existing anemometer bracket is installed at the tail of the nacelle, which leads to turbulent wake, resulting in distorted wind measurement data, high risk of equipment wear, inconvenient operation and maintenance, and serious interference from hot airflow, affecting the control accuracy and safety of the wind turbine.
Design a ventilation cover adapter structure for an anemometer bracket, which adopts a bracket base, support arm, central column and quick-release mounting flange, combined with high-strength bolts and shock-absorbing protection components. The installation position is moved to the windward side of the ventilation cover to avoid the wake area, and vibration is attenuated by rubber damping pads and spring dampers to achieve quick assembly and disassembly.
It significantly improves wind measurement accuracy, enhances structural stability, extends equipment life, reduces operation and maintenance costs and safety risks, and improves wind turbine power generation efficiency.
