The invention discloses an offshore wind power anti-scouring device with energy dissipation nails. The offshore wind power anti-scouring device with the energy dissipation nails comprises a pile foundation, a sleeve and the energy dissipation nails, wherein the pile foundation comprises a first part and a second part which are connected with each other 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 is arranged on the first part in a sleeving mode, the bottom of the sleeve is supported on the seabed surface, the energy dissipation nails which protrude outwards are arranged on the peripheral face of the sleeve, the ratio of the size of the energy dissipation nails in the axial direction of the sleeve to the size of the energy dissipation nails in the circumferential direction around the sleeve is larger than or equal to 1 / 2 and smaller than or equal to 2, a plurality of energy dissipation nails are arranged at intervals in the axial direction of the sleeve and / or in the circumferential direction around the sleeve, the outer diameter of the sleeve is De, and the interval between every two adjacent energy dissipation nails is larger than or equal to 0.25 De and smaller than or equal to 1.0 De. The offshore wind power anti-scouring device with the energy dissipation nails has the advantages of good turbulence effect, high stability and the like.
Description
technical field [0001] The invention relates to the field of offshore wind power, in particular to an anti-scouring device for offshore wind power with energy dissipation nails. 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...
