Description

Technical Field

[0001] The utility model relates to the technical field of industrial and agricultural wind speed measuring equipment, in particular to a novel ultrasonic wind speed sensor probe. Background Art

[0002] In traditional agriculture or industry, most instruments that measure wind speed use wind cups as sensors. Wind cups mainly use physical principles. When wind blows through the rotor, the rotor will rotate. By measuring the rotation speed of the rotor, the wind speed can be calculated. The rotation speed of the rotor is proportional to the wind speed. At present, with the development of science and technology, ultrasonic wind speed sensor probes are gradually being used to increase agricultural production and efficiency and provide accurate data for industrial production and life. Ultrasonic wind speed sensor probes mainly use the propagation speed of ultrasound to measure wind speed. It contains a transmitter and a receiver. The transmitter sends out an ultrasonic signal and the receiver receives the echo. When ultrasound propagates in the air, the wind speed will affect the propagation time of the echo. By measuring the propagation time difference of ultrasound, the wind speed and direction can be calculated.

[0003] At present, the wind cups on the market are mainly physical structures. Since they are always exposed to the outdoors, the internal rotor bearings are greatly affected by rain and snow, which can easily cause large bearing resistance, thus failing to achieve actual measurement data and affecting the accuracy of the equipment. Although ultrasonic wind speed sensors are relatively advanced and have high accuracy, they are also greatly affected by the external environment. In the cold winter, at temperatures below zero, the air contains more water vapor, which is easy to condense at the measuring end of the sensor probe, resulting in equipment failure or inaccurate data measurement. In rainy and snowy weather, due to the different temperatures in the morning, noon and evening, ice is likely to form at night where the ultrasonic probe is located, which can also cause equipment failure. Therefore, a new type of ultrasonic wind speed sensor probe is proposed to solve the above problems. Utility Model Content
