Method for measuring gradient of wind generating set tower

Abstract

The invention discloses a method for measuring a gradient of a wind generating set tower, which comprises the following steps of firstly arranging a base on the lower part of a wind generating set tower drum, arranging a longitudinal shaft with an equivalent plane being parallel to the wind generating set tower drum on the base, determining the orientation of a laser beam which is vertical to the longitudinal shaft of the wind generating set tower drum by utilizing a right-angled plate and an inclined indicating instrument, arranging a theodolite in the direction pointed by the laser beam to observe the top and the bottom of the wind generating set drum, recording a corresponding direct telescope angle and a corresponding inverted telescope angle, to conveniently calculate the gradient of the wind generating set tower drum. Due to the adoption of the method, the error of the measured gradient value of the wind generating set tower drum is further reduced, the traditional method for measuring the gradient of a building by utilizing the theodolite is changed, and the gradient measurement steps are simplified.

Description

technical field [0001] The invention relates to a method for measuring a tower of a cylindrical wind power unit, in particular to a method for measuring the inclination of a tower of a wind power unit.

Wind turbines include wind rotors and generators. The wind rotors are composed of blades, hubs, reinforcements, etc. The blades of the wind turbines are rotated by the wind to generate electricity, and the generator head rotates. The tower is to ensure that the wind turbines The importance of the necessary support equipment for safe and normal operation is self-evident. In view of the long-term operation of the wind turbine, it is affected by various external forces, causing the tower to deviate from the original fixed position, that is, due to the settlement and deformation of the foundation of the tower. Tilting in a certain direction, when the inclination direction of the wind turbine tower in the wind farm cannot be observed in time or when there is a large deviation in the measured inclination value of a wind turbine tower in the wind farm, it will lead to Misjudgments in measurement technology can not guarantee the safe and normal operation of the wind turb
