Wind power plant ultrasonic wind speed detection device

The utility model relates to a wind power plant ultrasonic wind speed detection device which mainly comprises a base (1), a supporting structure and a circuit module. The base (1) is fixed on a wind detection mast or fixed frames in places, where wind speed needs to be tested, in a wind power plant, screw holes are formed in the center of the base (1), the base (1) is connected with a stainless steel barrel (2) of the supporting structure through screws, the supporting structure is fixed on the base (1), and the circuit module is arranged in the stainless steel barrel (2) of the supporting structure. Compared with an existing wind detection method, the wind power plant ultrasonic wind speed detection device can achieve the effect that in the wind speed detection process, influences on obtaining ultrasonic pulse signals in the ultrasonic wind speed detection device by the supporting structure, eddy covariance and other external conditions can be lowered to the minimum.
