Offshore wind turbine tower barrel inclination angle and foundation settlement measuring method and terminal

Abstract

The invention discloses an offshore wind turbine tower barrel inclination angle and foundation settlement measuring method and terminal. The method comprises the steps of obtaining three-dimensional space coordinates of three points on the same outer circumference of the top of a tower barrel, the three points on the same outer circumference of the bottom of the tower barrel, and a reference pointon a height reference object; marking circles according to the three-dimensional space coordinates, thereby obtaining a first measurement circle and a second measurement circle; obtaining a first circle center and a second circle center according to the first measurement circle and the second measurement circle; obtaining a central axis of the tower barrel according to the first circle center andthe second circle center; carrying out comparison computing on the central axis and a vertical line, thereby obtaining a tower barrel inclination angle; carrying out computing according to the secondcircle center and the three-dimensional space coordinate of the reference point, thereby obtaining vertical height difference; and carrying out comparison computing on the vertical height differenceand initial height difference, thereby obtaining foundation settlement quantity. Rapid and accurate computing can be carried out to obtain the tower barrel inclination angle and the foundation settlement quantity. The measurement method is simple and reliable and is easy to realize.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a method and terminal for measuring the inclination angle of an offshore fan tower and foundation settlement. Background technique [0002] At present, the foundation structure forms of offshore wind turbines mainly include single pile foundation, tripod foundation, jacket foundation and pile cap foundation. These basic structures are subjected to complex and variable loads from unit gravity, thrust, bending moment and torque. After long-term operation, under the action of these complex loads, it may cause uneven settlement of the foundation structure, and then cause the wind tower to tilt. If the inclination angle of the tower is too large, it will affect the normal operation of the wind power generating set, and in severe cases, safety accidents such as tower collapse will occur, resulting in great losses. Therefore, regular measurements of the inclination angle of the t...
