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 3 An offshore wind power anti-scouring device according to an embodiment of the present invention will be described.

[0026] like Figure 1-3 As shown, the anti-scouring device for offshore wind power according to the embodiment of the present invention includes a pile foundation 1 and a sleeve 2 .

[0027] The pile foundation 1 comprises a first part 11 and a second part 12 interconnected in its axial 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. Specifically, the pile foundation 1 is a hollow cylindrical stru...

Abstract

The invention discloses an offshore wind power anti-scouring device with an energy dissipation structure. The offshore wind power anti-scouring device comprises a pile foundation and a sleeve, the pile foundation comprises a first part and a second part which are mutually connected in the axial 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 the sleeve sleeves the first part, the bottom of the sleeve is supported on the seabed surface, the energy dissipation structure is arranged on the sleeve, the energy dissipation structure comprises an energy dissipation piece protruding outwards from the peripheral surface of the sleeve and / or an energy dissipation hole penetrating through the peripheral wall of the sleeve, the peripheral surface of the sleeve comprises a front surface facing the tidal current direction, a back surface opposite to the front surface and two side surfaces, and the energy dissipation structure is at least arranged on the front face and the back face. The offshore wind power anti-scouring device with the energy dissipation structure has the advantages of being simple in structure, high in tide impact resistance, long in service life and the like.

Description

technical field [0001] The present application relates to the field of new energy technologies, in particular to an offshore wind power anti-scouring device with an energy dissipation structure. 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...
