Anti-scouring structure of offshore wind power foundation
The invention belongs to the technical field of wind power generation, and relates to an anti-scouring structure of an offshore wind power foundation, which comprises a pile foundation and a wing-shaped anti-scouring column arranged outside the pile foundation, the wing-shaped anti-scouring column comprises a curved surface body, an upper top cover and a lower bottom plate, the curved surface body, the upper top cover and the lower bottom plate are closed to form a hollow cavity, and the curved surface body is composed of two symmetrical arc-shaped curved surfaces; the upper top cover and the lower bottom plate are provided with round holes used for containing pile foundations. The arc-shaped curved surface of the curved surface body is of a wing-like structure; the front surface, opposite to the water flow direction, of the curved surface body is a convex arc-shaped surface, the rear surface, opposite to the water flow direction, of the curved surface body is a concave arc-shaped surface, the concave arc-shaped surface is an arc-shaped gradually-shrinking surface, and the length of the convex arc-shaped surface is smaller than that of the arc-shaped gradually-shrinking surface. The device is simple in structure, flow separation after the pile foundation is scoured by seabed water flow is delayed or avoided through the wing-shaped anti-scour columns, and therefore scour pits are prevented from being formed.
本发明属于风力发电技术领域，涉及一种海上风电基础的防冲刷结构，包括桩基础，及设置在桩基础外的翼型防冲刷柱；所述翼型防冲刷柱包括曲面体、上顶盖和下底板，曲面体、上顶盖和下底板封闭形成空心腔体，曲面体由对称的两弧形曲面构成；在上顶盖和下底板上开有用于容纳桩基础的圆孔；曲面体的弧形曲面为仿翼形结构；曲面体上与水流方向相对的前表面为凸弧型面，与水流方向相背的后表面为凹弧型面，且凹弧型面为弧形渐缩面，凸弧型面的长度小于弧形渐缩面的长度。本发明结构简单，通过翼型防冲刷柱，延后或避免了海底水流冲刷桩基础后的流动分离，进而避免了冲刷坑的形成。
