Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic wind speed sensor installation, in particular to an ultrasonic wind speed sensor installation centering device. Background Art

[0002] The sensors used to measure wind speed and wind direction at the meteorological station of wind turbines mainly use ultrasonic wind speed sensors. This type of sensor has high measurement accuracy, high response sensitivity and high reliability, but all its advantages are based on the precise installation of the sensor itself. An initial angle is calibrated on its mechanical structure. When installing the sensor, it is particularly important to accurately align the initial angle. The traditional installation method is to use the naked eye for comparison, which has a large error. The installation error leads to inaccurate wind, which in turn causes power loss and eccentric loads on the unit. How to improve the installation accuracy of ultrasonic sensors has high research value. Utility Model Content
