Embodiment Construction

[0034] 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.

[0035] The following is based on Figure 1-Figure 8 The offshore wind power foundation 1 according to the embodiment of the present invention is described. The offshore wind power foundation 1 includes a pile foundation 11 and a spoiler structure.

[0036] The pile foundation 11 includes a first part 111 and a second part 112 interconnected in its length direction, and the second part 112 is buried in the seabed. The seabed has a seabed level 2, a first part 111 is located above the seabed level 2 and a second part 112 is located below the seabed level 2 . Those skilled in the art know that the currently commonly used pile foundations 11 are all hollow cylindri...

Abstract

The invention provides an offshore wind power foundation. The offshore wind power foundation comprises a pile foundation and a turbulent flow structure. The pile foundation comprises a first part and a second part which are mutually connected in the length direction of the pile foundation, the second part is embedded in a seabed, the seabed is provided with a seabed surface, the first part is located above the seabed surface, and the turbulent flow structure is at least arranged on the first part. The turbulent flow structure comprises turbulent flow pieces protruding from the peripheral face of the first part in the first direction and / or turbulent flow holes penetrating through the peripheral wall of the first part in the first direction, and the first direction is orthogonal to the length direction of the pile foundation. The turbulent flow structure is arranged, so that the effects of energy dissipation and impact reduction are achieved, formation of horseshoe-shaped vortexes near the pile foundation is restrained, soil around the pile foundation is effectively protected, and formation of scour pits is avoided. Compared with a riprap protection method in the related technology, the stability is higher, the anti-scouring effect is better, and the reliability is better.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to an offshore wind power foundation. 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] 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 an impact on the stability of the pile foun...
