Embodiment Construction

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0022] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an anti-scouring offshore wind turbine foundation. The anti-scouring offshore wind turbine foundation comprises a foundation body, an anti-scouring coating layer and an anti-scouring clamping ring, wherein the anti-scouring clamping ring is arranged on the foundation body in a sleeving mode, the anti-scouring clamping ring and the anti-scouring coating layer are arranged at an interval. The anti-scouring coating layer is arranged on the surface of a seabed in a covering mode, so that the protective effect on the seabed around the foundation body is achieved; further, when a water flow flows around the foundation body, the anti-scouring clamping ring can play a role in breaking a turbulent flow field and reducing shearing stress of the water flow around the foundation body, so that the scouring capability of the water flow is greatly weakened; on one hand, the scouring action of the water flow on the seabed can be weakened; and on the other hand, weakening of the water flow scouring capacity can further prevent the anti-scouring coating layer from being quickly scoured, so that the anti-scouring coating layer is kept for a long time, the continuous protective effect on the seabed is achieved, and therefore, the anti-scouring effect of the above anti-scouring offshore wind turbine foundation is good.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to an anti-scouring offshore wind turbine foundation. 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 have emerged, mainly including high pile cap foundations, jacket foundations, single pile foundations, and barrel foundations. The study found that since the surface soil of the seabed is mostly loose fine sand or silt in a flow-plastic state with low strength, serious erosion is prone to occur around the single-pile foundation and single-barrel foundation. During the long-term service of wind turbines, the erosion phenomenon will cause the foundation of the wind turbine to be unstable and affect the normal operation of the wind turbine. [0003] At present, it is necessary to carry out anti-scouring treatment on the foundation o...
