Description
Technical Field
The invention relates to the technical field of wind power generation anemometry towers, in particular to a method for accurately mounting a mechanical anemoscope on a wind power generation anemometry tower.
Background
The wind power generation field requires accurate measurement of wind direction to count the main wind direction of the area or be used for wind direction measurement during testing, the wind direction in the wind power industry is defined as follows, 0 degrees represents positive north wind, 90 degrees represents positive east wind, 180 degrees represents positive south wind, 270 degrees represents positive west wind, and the like.
The anemoscope is a sensor for measuring wind direction and mainly comprises a mechanical anemoscope and an ultrasonic anemoscope, the mechanical anemoscope has the working principle that wind firstly blows over the head of the anemoscope and then blows over the tail pendulum, the tail pendulum drives the vertical shaft to rotate under the action of wind force, the vertical shaft rotates for a circle corresponding to 0-360 degrees, when the vertical shaft rotates clockwise generally, the angle is increased, a N point mark, namely a starting 0 point, is arranged on the base of the anemoscope, and when the head of the anemoscope is aligned with the N point mark, the head of the anemoscope outputs corresponding to 0 degree. However, when the head of the anemoscope is aligned with the N-point marker, the indicated 0 degree is not the true north angle, and the north angle pointed by the N-point marker needs to be considered and the output value needs to be corrected to be the true north angle, for example, when the anemoscope is installed, the N-point marker points to 45 degrees, i.e., the northeast direction, and when the anemoscope is operated and the output value is displayed to be 90 degrees, the true wind direction should be 135 degrees, i.e., the southeast wind. Therefore, the orientation of the N-point mark is very important.
At present, the general method in the industry is that when the anemoscope is installed, the base of the anemoscope is rotated by observing and adjusting with naked eyes, the N point is marked to be approximately directed to the center of a vertical support, namely, the vertical support is directed to a horizontal support, then a bolt of the anemoscope and the support is fastened, the support with the anemoscope is hoisted and installed at the high altitude of a wind measuring tower, a person stands on the ground, observes the north angle of the support by a compass, and then corrects the output angle value of the anemoscope by the north angle to obtain the true north angle of the anemoscope. The principle of the method is that the true north-to-north angle of the wind direction instrument is corrected by deducing the orientation of the N-point mark according to the north-to-north orientation of the bracket, so that whether the N-point mark is completely aligned with the horizontal bracket in the method is very important.
The method for observing and adjusting the N point marks of the anemoscope by naked eyes to enable the N point marks to approximately point to the center of the support is free of data and method support, and is judged by individuals, so that a large error is inevitably generated, the error is less, the degree is 3-5 degrees, and the error is possibly 10 degrees.
