Ultrasonic wind speed and direction sensor

Abstract

The utility model provides an ultrasonic wind speed and direction sensor, an upper cover is detachably connected with a base, the upper surface of the upper cover is connected with a stand column, and the top of the stand column is connected with a reflecting screen part; each probe fixing frame is provided with an opening, an ultrasonic probe is arranged in each opening, the four probe fixing frames are circumferentially and uniformly arranged on the upper surface of the upper cover, every two probe fixing frames with opposite openings form a group, in the two probe fixing frames in the same group, the ultrasonic probe in one probe fixing frame is a transmitting end, and the ultrasonic probe in the other probe fixing frame is a receiving end. The ultrasonic probe in one probe fixing frame is a receiving end, the ultrasonic probe in the other probe fixing frame is a receiving end, a first electrothermal film is arranged in the opening of each probe fixing frame, and the first electrothermal film surrounds the ultrasonic probe; a circuit module is further arranged, and the circuit module is electrically connected with the ultrasonic probe and the first electrothermal film. The heating film is arranged to heat the periphery of the ultrasonic probe, and the problem that ice and snow are accumulated around the ultrasonic probe to affect the measurement accuracy is solved.
