Problems solved by technology
However, during the service period, in the face of complex marine environments, especially cyclic loads such as wind loads and wave loads, and extreme weather such as typhoons, there is still a lack of design methods for anti-tilting and deflection correction for the in-situ working condition of the wind turbine foundation. Tilts too far to function properly and even risks capsizing

Abstract
The invention relates to the technical field of offshore wind power foundation engineering, in particular to an offshore wind power five-connected-cylinder foundation intelligent in-place inclination rectifying system which comprises a five-connected-cylinder foundation structure and an intelligent control system. The five-connected-cylinder foundation structure is integrally composed of five semi-closed cylinder bodies with openings in the bottoms, and the five-connected-cylinder foundation structure comprises a middle cylinder and four side cylinders. The intelligent control system comprises a battery management system, a tilt angle sensor, a data processor, a controller, an electromagnetic valve, a vacuum pump, a one-way valve, a flow dividing pipe and a flow collecting box. The structural form of the foundation is improved, the interlayer plate is additionally arranged, an operation space is provided for negative pressure extraction in the foundation, it is guaranteed that the bearing performance of the foundation is not affected, meanwhile, the middle cabin interlayer provides a closed space for storage of intelligent control equipment, the equipment does not need to be exposed in seawater to be collided or corroded, and the service life of the equipment is prolonged. And a new scheme is provided for negative pressure deviation rectification during basic in-place operation.
Description
technical field [0001] The invention relates to the technical field of offshore wind power foundation engineering, in particular to an intelligent in-position rectification system and a control method for the five-connected cylinder foundation of offshore wind power. Background technique [0002] In recent years, with the development of offshore wind power to deep sea and large capacity, traditional foundation structures such as single pile foundation and gravity foundation are no longer applicable due to high cost and difficulty in construction. It is urgent to choose an economical and stable foundation structure. basic type of wind power. The emergence of wide and shallow barrel foundations for offshore wind power provides a new direction for the design of offshore wind turbine foundations. Its wide and shallow design enables offshore wind turbines to resist large overturning loads and effectively control differential settlement of foundations. The integrated installation...
