[0002] The wind speed and direction instrument plays a vital role in meteorological observation, aviation, navigation and wind power generation and many other fields. However, in cold weather or high-altitude areas, the wind speed and direction instrument is prone to icing, which will affect the normal work of the wind speed and direction instrument and lead to inaccurate measurement of meteorological data.

[0003] Therefore, a heating structure is provided, which sets the wind sensing blade of the wind speed and direction instrument as multiple layers and adds a heating body in the wind sensing blade to avoid icing of the wind sensing blade.

[0004] The wind sensing blade is connected with the wind speed sensor through a rotating shaft, and a sleeve is arranged outside the rotating shaft. Although the above-mentioned heating structure can avoid icing imbalance of the wind sensing blade, the ice layer on the wind sensing blade will melt and fall between the rotating shaft and the sleeve outside the rotating shaft, which will freeze the rotating shaft and freeze the sleeve, so that the rotating shaft cannot rotate and affect the wind detection.
