Abstract

The invention discloses an offshore wind power foundation with a sand guiding function. The offshore wind power foundation with the sand guiding function comprises a pile foundation, an anti-sinking plate and a sand guiding assembly, the outer contour of the cross section of the pile foundation is circular, the pile foundation is at least partially buried in a seabed, the seabed is provided with a seabed surface, an anti-sinking plate sleeves the pile foundation, and the lower surface of the anti-sinking plate is suitable for being attached to the seabed surface; and the sand guiding assembly comprises a sand guiding pipe and a driving part, the sand guiding pipe is arranged on the upper surface of the anti-sinking plate, the sand guiding pipe is used for guiding sand on the peripheral side of the anti-sinking plate to the pile foundation, and the driving part is connected with the sand guiding pipe and used for driving the sand guiding pipe to guide sand. The offshore wind power foundation with the sand guiding function has the advantages of being simple in structure, safe, reliable and good in anti-scouring effect.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to an offshore wind power foundation with the function of guiding sand. 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 with the function of guiding sand 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, and the accidents of offshore wind turbines are mostly 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 sc...
