Abstract

The invention discloses an offshore wind power foundation with an active desilting function. The offshore wind power foundation with the active desilting function comprises a pile foundation, a fixing frame, a sand guide worm and a driving wheel, 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, the fixing frame is arranged on the peripheral side of the pile foundation and connected with the pile foundation, the sand guiding worm is connected with the fixing frame and used for guiding sand on the peripheral side of the pile foundation to the pile foundation, the rotating center line of the driving wheel is orthogonal to the sea level, the driving wheel is connected with the sand guiding worm, and the driving wheel is suitable for being pushed by seawater to rotate so as to drive the sand guiding worm to guide the sand. The offshore wind power foundation with the active desilting 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 an active sand discharge function. 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 active sand removal function is the key to supporting the entire offshore wind turbine. 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 for...
