Ultrasonic wind sensor with tetrahedral structure

The utility model relates to an ultrasonic wind sensor with a tetrahedral structure, which comprises ultrasonic probes arranged on both a bracket and a base, a support positioned between the bracket and the base, and a control cabinet positioned below the base; the ultrasonic wind sensor is characterized in that one probe is vertically arranged on the bracket or the base, three probes are arranged on the base or the bracket, and the four center points of the top end surfaces of the four ultrasonic probes are taken as four apexes of a spatial tetrahedron; or one ultrasonic probe is vertically arranged on the base, and three ultrasonic probes are arranged on the bracket; and the plane determined by the center points of the top end surface of the three ultrasonic probes installed on the bracket or the base is parallel to the horizontal plane, and the tetrahedron can be a regular tetrahedron, a rectangular tetrahedron or other tetrahedrons. The number of the probes is reduced to four from six, so that not only ca
