Anti-scouring offshore wind turbine

Abstract

The invention relates to an anti-scouring offshore wind turbine. An anti-scouring area formed by a plurality of splicing layers protects a wind turbine foundation from being scoured. A supporting framework can support an earth cushion layer to improve the flatness of the earth cushion layer and prevent corners from curling, and thus the stability of an earth cushion layer structure is improved. However, the splicing layers are overlapped with each other, and limiting does not form between the splicing layers, so that different splicing layers can fluctuate along with seabed terrain, and therefore the seabed is better covered. Moreover, the anti-scouring area can self-adapt to the seabed terrain. With the scouring deformation of the seabed, the corresponding splicing layers can further adjust the angle and height correspondingly under the action of own gravity, and thus excessive clearances between the splicing layers and the seabed are avoided. Therefore, the anti-scouring area formedby the splicing layers can be dynamically adjusted, so that the seabed around the wind turbine foundation can be well covered all the time. It can be seen that the anti-scouring offshore wind turbinehas a better anti-scouring effect.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to an anti-scour offshore wind power fan. Background technique [0002] In recent years, with the gradual acceleration of the development of domestic offshore wind energy resources, various forms of offshore wind turbine foundations continue to emerge, mainly including high-pile cap foundations, jacket foundations, single-pile foundations, and barrel foundations. The study found that since the topsoil of the seabed is mostly loose fine sand or silt in a flow-plastic state with low strength, the surrounding areas of single pile foundations and single bucket foundations are prone to serious scouring. During the long-term service of the wind turbine, the scouring phenomenon will cause the foundation of the wind turbine to be unstable and affect the normal operation of the wind turbine. [0003] At present, the foundation of the fan needs to be anti-scour during the constru...

Problems solved by technology

[0004] Based on this, it is necessary to provide an offshore wind turbine with a better anti-scouring effect in view of the problem that the existing protective structure has a poor anti-scouring effect on the fan foundation.
