REFLECTION UNIT AND ULTRASONIC ANEMOMETER

WIPO Patent Application WO/2021/062949

A1

Disclosed is a reflection unit (130) applied to an ultrasonic anemometer. The reflection unit (130) is used for reflecting ultrasonic waves from an emitter (110) and enabling the reflected ultrasonic waves to be received by a receiver (120). The reflection unit (130) comprises a reflection plate (210), and further comprises a net-shaped covering layer (220) in terms of structure, and the net-shaped covering layer (220) covers the upper surface of the reflection plate (210). Due to the fact that the net-shaped covering layer (220) is arranged on the reflection plate (210), raindrops/droplets of water falling onto the reflection unit (130) can be rapidly scattered on the surface of the reflection unit (130), and as such, accumulated liquid formed on the surface of the reflection unit (130) and irregular in terms of shape and height is eliminated, such that the measurement accuracy of the ultrasonic anemometer under the windy and rainy conditions is guaranteed.
