Embodiment Construction

[0024] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0025] The following is based on Figure 1-Figure 2 An offshore wind power foundation with a spoiler net 2 describing an embodiment of the present invention includes a pile foundation 1 and a spoiler net 2 .

[0026] Pile foundation 1 includes in its length direction (such as figure 1 As shown, the first part 11 and the second part 12 connected to each other on the up and down direction), the second part 12 is buried in the seabed, the seabed has a seabed surface, and the first part 11 is located above the seabed surface. Those skilled in the art know that the currently commonly used pile foundations 1 are all hollow cylindrical structures.

Abstract

The invention provides an offshore wind power foundation with a turbulent flow net. The offshore wind power foundation with the turbulent flow net comprises a pile foundation and the turbulent flow net, the pile foundation comprises a first part and a second part which are connected with each other in the length direction of the pile foundation, the second part is buried in a seabed, the seabed is provided with a seabed surface, and the first part is located above the seabed surface; and and the turbulent flow net is located above the seabed surface, the turbulent flow net is at least arranged on the first part, the turbulent flow net protrudes from the peripheral face of the first part in the first direction, the first direction is orthogonal to the length direction of the pile foundation, the turbulent flow net is of a net structure wrapping at least one part of the peripheral face of the first part, the outer diameter of the first part is D, and the area of the peripheral surface of the first part wrapped by the turbulent flow net is larger than or equal to 1.0 piD2. The offshore wind power foundation with the turbulent flow net has the advantages of being simple in structure, high in practicability, long in service life and the like.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to an offshore wind power foundation with a spoiler net. Background technique [0002] As a clean and harmless renewable energy, wind energy has been paid more and more attention by human beings. Among them, compared with land wind energy, offshore wind energy resources not only have higher wind speeds, but also are farther away from the coastline, and are not affected by noise limits, allowing larger unit manufacturing. [0003] In related technologies, the offshore wind power foundation is the key to supporting the entire offshore wind turbine, and the cost accounts for about 20% to 25% of the entire offshore wind power investment. However, most accidents in offshore wind turbines are caused by unstable pile foundations. Due to the action of waves and tidal currents, the sediment around the offshore wind power pile foundation will be scoured and form scour pits, which will have...
