Problems solved by technology

However, the general anti-scouring devices for offshore wind power foundations often have inconsistent protection coverage areas and actual scour conditions. The protection stability is insufficient and it is easy to be washed away, losing the proper protection effect, and the offshore construction is difficult, which improves the construction efficiency. cost and reduced construction efficiency

Embodiment Construction

[0024] 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, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0025] 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. In contrast, when an element is referred to as being "directly on" another element, there are no intervening ele...

Abstract

The invention relates to an offshore wind power foundation erosion preventing device. The device comprises at least two geotechnical protection pads for surrounding an offshore wind power foundation.In the offshore wind power foundation erosion preventing device, on the one hand, a weight in an accommodating cabin achieves a fixing effect to prevent the geotechnical protection pads from dashing away under the effect of waves and ocean currents; and the at least two geotechnical protection pads are surrounded annularly, and are arranged around the offshore wind power foundation to comprehensively protect the offshore wind power foundation. On the other hand, in two adjacent geotechnical protection pads, an empty area without the weight is formed in the accommodating cabin of one geotechnical protection pad, and the other geotechnical protection pad is pressed in the empty area through the weight in the accommodating cabin; through the mode, the connection between two adjacent geotechnical protection pads can be realized, and the overall protection stability is improved; and during constructing, the manufactured geotechnical protection pads are laid around the offshore wind power foundation, so that the construction process is simple, the construction cost is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of offshore wind power foundations, in particular to an anti-scouring device for offshore wind power foundations. Background technique [0002] In recent years, with the gradual acceleration of the development of offshore wind energy resources, various forms of offshore wind power foundations have emerged, such as 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, the strength is low, and the surrounding areas of single-pile foundations and barrel foundations are prone to serious erosion. The scour phenomenon not only increases the horizontal deformation of the offshore wind power foundation, which is not conducive to maintaining the stability of the structure, but also reduces the overall stiffness of the offshore wind turbine, resulting in a decre...
