Single column type offshore wind driven generator foundation structure

Abstract

The invention provides a single column type offshore wind driven generator foundation structure. The single column type offshore wind driven generator foundation structure comprises a foundation column body and multiple suspension cable assemblies arranged on the peripheral face of the foundation column body. All the suspension cable assemblies are evenly arranged in the circumferential directionof the peripheral face of the foundation column body. Each suspension cable assembly comprises a suspension cable supporting frame and a suspension cable part. The upper ends and the lower ends of thesuspension cable parts are connected with the peripheral face of the foundation column body. One end of each suspension cable supporting frame is connected with the foundation column body, and the other end of each suspension cable supporting frame is connected with the corresponding suspension cable part to support the suspension cable part. Each suspension cable part is divided by the corresponding suspension cable supporting frame into an upper inclined cable portion and a lower inclined cable portion. The single column type offshore wind driven generator foundation structure is light in structural design, the bending moment of the foundation column body can be effectively reduced, and the foundation work amount is small.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a single-column offshore wind power generator basic structure. Background technique [0002] Offshore wind turbine foundations are divided into two types: fixed foundations and floating foundations. For shallow water areas, fixed foundations are generally used. Fixed foundations are greatly affected by seabed geological conditions and water depth conditions, and the engineering volume is large and the construction process is relatively complicated. For deep-sea areas, floating foundations are generally used. Floating foundations include single-column foundations, semi-submersible foundations, and tension-leg foundations; semi-submersible foundations are large in size, which increases the difficulty of construction and towing; Tendon performance requirements are high, and high-frequency vibration is likely to cause fatigue damage; the single-column foundation is genera...

Problems solved by technology

For shallow water areas, fixed foundations are generally used. Fixed foundations are greatly affected by seabed geological conditions and water depth conditions, and the amount of engineering is large and the construction process is relatively complicated.

For deep-sea areas, floating foundations are generally used. Floating foundations include single-column foundations, semi-submersible foundations, and tension-leg foundations; semi-submersible foundations are large in size, which increases the difficulty of construction and towing; Tendon performance requirements are high, and high-frequency vibration is likely to cause fatigue damage; the single-column foundation is generally a huge upright cylinder, which relies on buoyancy to support equipment on the water surface, and its stability comes from the fact that the center of gravity is lower than the center of buoyancy. And it is fixed by chain anchor cable, but the single-column foundation requires deeper water depth
