Background technique

The structure of the wind speed sensor mainly includes a base and a wind cup. The wind cup is installed on the base through a connecting bar and can be rotated freely. The wind speed is measured by the rotation speed of the wind cup. Because the wind speed sensor needs to work in a position where the air is smooth when measuring, Therefore, wind speed sensors are generally directly installed in open areas such as mine heads and supports to better contact with the wind.

Since the wind cup is installed on the base through a cross bar, in order to reduce the friction when the wind cup rotates, the cross bar is generally thin and its robustness is limited. In some areas, severe weather conditions such as hail often occur. When hail occurs, it often Accompanied by strong wind and drastic changes in wind direction, the crossbar is easy to break due to repeated rotations. In addition, in this case, even if the wind speed sensor is installed in a place with a rain shield, there will be hail and debris in the strong wind. When the wind speed sensor is tilted and hits the sensor under the blow of the wind, the wind cup or the crossbar is damaged. The general wind speed sensor does not have a good protection device. In the event of hail and other bad weather, the wind speed sensor cannot be recovered and protected in time. It has to be repaired and replaced, which increases the use cost and repair time of the wind speed sensor.
