Abstract

The invention discloses an offshore wind power multi-pile foundation. The offshore wind power multi-pile foundation comprises a plurality of pile foundations, a platform and a sleeve, the multiple pile foundations are arranged at intervals, the platform is located on the multiple pile foundations, each 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 embedded in a seabed, the seabed is provided with a seabed surface, the first part is located above the seabed surface, the multiple pile foundations comprise first pile foundations right facing the tidal current direction and second pile foundations back to the tidal current direction, and outwards-protruding turbulent flow pieces are arranged on the peripheral face of the sleeve, and / or a through hole is formed in the peripheral wall of the sleeve, the sleeve comprises a first sleeve and a second sleeve, the first sleeve is arranged on the first part of a first pile foundation in a sleeving mode, and the second sleeve is arranged on the first part of a second pile foundation in the sleeving mode. The offshore wind power multi-pile foundation has good anti-scouring performance and stability.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to a multi-pile foundation for offshore wind power. 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...
