Description

Technical Field

[0001] The utility model relates to the technical field of antifreezing of wind direction and wind speed sensors, in particular to a heating anti-icing device for meteorological wind direction and wind speed sensors of high plateau airports. Background Art

[0002] Airports with an elevation of more than 2,438 meters are called high-plateau airports. All branch airports in Qinghai are located in the Qinghai-Tibet Plateau. The winter is cold and snowy, with an average temperature of minus 8°C and a minimum temperature of minus 30°C. Golog and Yushu, which have the most snowfall, have more than 40 days of snowfall, while the three Haixi airports, which have the least, have more than 20 days of snowfall. According to the Civil Aviation Air Traffic Management Regulations, take-off and landing with the wind are not allowed in case of runway contamination (snow, water, frost, ice, or humidity).

[0003] Meteorology requires accurate wind direction and speed sensor equipment. However, in winter, snow and precipitation under low temperature conditions cause ice or snow accumulation on wind speed and direction sensor equipment, which results in the wind direction and speed sensor being unable to work properly, directly leading to abnormal wind direction and speed parameters. At this time, there is often snowfall or other weather phenomena, which can easily lead to runway surface pollution. If the controller refers to the wrong meteorological wind direction and speed, it is easy for the aircraft to run off the runway and cause unsafe incidents. Utility Model Content

After the support plate 4 is fixed in the specified position, the support frame 6 is adjusted to rotate on the outside of the support plate 4 according to the direction of the sun. Under the action of the mounting slot 7 and the limit block 8, the support frame 6 can slide to the specified position on the outside of the support plate 4, and then be fixed by the fastening screws at the bottom of the support frame 6.
