Problems solved by technology

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 turbine tower, and even cause major safety hazards, and even major safety accidents. Therefore, the measurement of the wind turbine tower inclination is no trivial matter , if the traditional inclination measurement method is used to measure it, the numerical error of the measured inclination is still too large, and the existing methods for measuring the inclination of wind turbine towers or other circular structures are far from adequate Satisfying the current requirements of various industries is also a technical problem that needs to be solved urgently, especially for the measurement of the inclination of the wind turbine tower in the wind farm. Safety monitoring of the inclination of a wind turbine tower in the field
At present, the monitoring work on the inclination of the wind turbine tower tower is still blank, and the measurement method for the inclination of other circular structures will have problems of large measurement errors and too many measurement steps

Embodiment Construction

[0017] A method for measuring the inclination of a wind turbine tower, A, such as figure 1 with Figure 8 As shown, first, a base body 2 needs to be arranged on the lower outer wall surface of the wind turbine tower cylinder body 10 to be measured inclination close to the ground, and the equivalent plane 20 set on the base body 2 is identical to that of the wind turbine tower cylinder body. The axial geometric central axis o'o0 of 10 is parallel; the measuring tools to be prepared are: theodolite 6, scale 5, right-angle plate 3 and inclined vertical direction indicator; the height H of the tower shell 10 of the wind turbine is known;

[0018] Such as figure 1 , Figure 4 to Figure 8 As shown, the described inclined vertical direction indicator includes a disc-shaped omnidirectional level, which is composed of a circular flat box 4 and a circular transparent plate 43, and the circular transparent plate 43 is fixed It is packaged on the circular opening provided by the circul...

Abstract

The invention discloses a method for measuring the inclination of a tower of a wind power generating set. A body is arranged at the lower part of the tower of the wind power generating set in advance. The laser beam pointing perpendicular to the longitudinal axis of the wind turbine tower is determined by the plate and the inclined vertical direction indicator, and a theodolite is set up along the azimuth pointed by the laser beam to observe the top and bottom of the wind turbine tower, and record the corresponding positive and negative points. The angle of the inverted mirror can conveniently measure and calculate the inclination of the tower of the wind power generating set. The invention further reduces the error of the measured inclination value of the tower shell of the wind power unit, changes the traditional method of measuring the inclination of a structure with a theodolite, and simplifies the steps of measuring the inclination.
