Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wind vanes, and in particular relates to a wind vane positioning device on a wind measuring tower. Background Art
[0002] Wind towers are a crucial component of load and power characteristic testing during wind turbine type certification. The purpose of establishing a tower for a prototype is to accurately reflect the wind resource conditions within the prototype's range. According to statistical analysis, a 10% error in wind data can result in an error of approximately 30% in the wind turbine's annual production capacity. Inaccurate wind resource data can lead to misjudgments of turbulence, extreme wind speeds, and wind direction, which can even fundamentally affect the calculation and determination of loads on the turbine, posing a significant risk to subsequent turbine certification and safe operation. The tower's height is generally aligned with the turbine's hub center height (mostly over 100 meters). Prototype towers typically utilize a guyed-wire structure, which offers more balanced load distribution and high reliability. The tower's cross-section is small, requiring minimal tower material. The triangular truss structure is typically stable, subjecting the tower to minimal wind loads, providing strong wind resistance, and offering the most economical performance. Anemometers, wind vanes, and monitoring equipment for temperature, humidity, and air pressure are installed at various heights on the tower.
[0003] A document with publication number (CN117847359A) was retrieved and disclosed a wind vane positioning device for a wind turbine wind tower, comprising a positioning support plate, a threaded hole being provided on the top of the positioning support plate, a wind vane body being provided on the top of the positioning support plate, a limited fixing ring being fixedly connected to the top of the positioning support plate, and the interior of the limited fixing ring being hollowed out.
[0004] The above device fixes the positioning support plate to the wind measurement tower with fastening bolts through threaded holes, which facilitates the installation and disassembly of the positioning device. When the wind vane needs to be positioned, the wind vane is placed on the central axis at the top of the positioning support plate. The staff rotates the wind vane body to make the L-shaped buckle pass through the annular groove and enter the connecting cavity. Continuing to rotate will cause the L-shaped buckle to be stuck in the positioning support plate, preventing the wind vane body from moving up and down and falling due to vibration of the wind measurement tower.
[0005] The above device only has the function of fixing and restricting the wind vane, but during high-altitude operations, when encountering strong winds and collisions, the above device does not have the effect of buffering and shock resistance, causing the wind vane to be shaken by external forces, resulting in damage to the wind vane.
