The invention provides a novel torque type wind vane comprising a wind speed measuring assembly and a data processing assembly, and further comprising a torque measuring assembly; the torque measuring assembly comprises a base, a main windward plane, an auxiliary windward plane, a first static torque meter, a second static torque meter and a torque output plug; and the wind speed measuring assembly comprises a three-cup anemometer and a wind speed output plug. According to the invention, the defects of increased centering deviation, reduced precision and the like which are inevitably generated after a traditional mechanical wind vane works in a relatively severe working environment for a long time can be eliminated, the service life is long, and the later maintenance cost is greatly reduced compared with that of a mechanical wind vane. Meanwhile, the novel torque type wind vane is low in manufacturing cost, so that the problem that the use range of an ultrasonic anemorumbometer and a laser wind finding radar is limited due to high cost is solved, more accurate and reliable wind direction data are provided for a yaw system of a wind turbine generator, the wind energy utilization efficiency of the wind turbine generator is improved, and the generating capacity of the wind turbine generator is improved.
Description
technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a novel torque vane. Background technique [0002] There are two main types of anemometers and vanes currently used in wind farms: mechanical anemometers and ultrasonic anemometers. [0003] Among them, the mechanical wind speed vane is used more, which uses the rotation of mechanical parts to measure the wind speed, and combines the direction of the wind vane to obtain the wind direction. Although this method is simple, reliable and low in cost, because the measurement part has contact movable parts, In the case of long-term exposure to the outdoors in the working environment, it is easy to wear, has a limited life and high maintenance costs. At present, the existing Chinese utility model patents with the application number CN200920004214.0 titled "Anemometer and Wind Vane Device" and the application number CN201721742951.1 titled "A Wind Cup Anemometer"...
