Problems solved by technology

[0002] As a kind of green energy, wind power generation is strongly supported by the country. However, to ensure the normal and safe operation of wind turbines, the monitoring of wind speed and direction is an important task. The most widely used wind measuring equipment is the wind cup, wind direction Combination tester has the advantages of low cost and wide test range, but its main problem is that the mechanical rotating parts are easy to wear, the wind speed is lower than the actual situation when the wind direction is irregular, and freezing, sediment and dust may occur in severe climate areas Blockage, even fracture, and is susceptible to lightning interference and other electromagnetic wave interference; ultrasonic wind measurement technology has high precision and good performance, but it is only under research in China at present, and foreign products are expensive and difficult to popularize

Abstract

The invention discloses a monitoring apparatus for a wind speed and a wind direction. The apparatus comprises a support bar, a pedestal, a rotating shaft, a movable plate, a housing, a test unit and a processing unit. The support bar is arranged in the housing and a spherical wind measurement device is arranged on the support bar. The pedestal is arranged below a dust cover. The rotating shaft is installed on the housing. The movable plate is fixed at the lower end of the support bar; a fixed plate is fixed at an inner wall of the housing; and a curve type support is arranged between the fixed plate and the movable plate. A plurality of first A side deformation gears and a plurality of first B side deformation gears are continuously laid at two opposite sides on the curve type support; and curve channels that are used for enabling one or a plurality of first signal fibers to pass are formed between heads of the plurality of first A side deformation gears and the plurality of first B side deformation gears. The test unit is connected with the first signal fibers and the processing unit is connected with the test unit. According to the apparatus provided in the invention, a fiber sensing technology is employed; and the apparatus has advantages of electromagnetic interference resistance and dustproof property and the like. Therefore, the apparatus has wide application prospects.
