Embodiment Construction

[0026] 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.

[0027] 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-scour offshore wind power fan. An anti-scour region which is formed by a plurality of splicing layers conducts anti-scour protection on a fan foundation. Supporting frameworks can support geotextile cushion layers, the flatness of the geotextile cushion layers is improved, the corners cannot be prone to curling, and therefore the stability of the structures of thegeotextile cushion layers is improved. The multiple splicing layers are connected with each other in an overlap joint mode and cannot be limited with each other, and therefore different splicing layers can heave along with the terrain of the seabed and preferably cover the seabed. In addition, the anti-scour region can adapt to the terrain of the seabed by itself. The corresponding splicing layerscan also correspondingly adjust the angles and the heights along with the scour deformation of the seabed, and therefore the overlarge gaps are prevented from being formed between the splicing layersand the seabed. As a result, the anti-scour region which is formed by the multiple splicing layers can achieve dynamic adjustment and preferably cover the seabed on the periphery of the fan foundation all the time. It can be seen that the anti-scour offshore wind power fan is good in anti-scour effect.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to an anti-scouring offshore wind turbine. 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 of the fan d...
