Offshore wind turbine composite cylindrical foundation of support-free single-column structure
The invention belongs to the field of offshore wind turbines, and provides an offshore wind turbine composite barrel type foundation of a support-free single-column structure, which comprises a thin-wall outer barrel, a thin-wall inner barrel arranged at the central position of an inner cavity of the thin-wall outer barrel, a single-column transition section arranged on the thin-wall outer barrel and used for being connected with a wind turbine tower barrel, and a single-column foundation arranged between the thin-wall outer barrel and the single-column transition section and used for being connected with a wind turbine tower barrel. The conical variable-diameter force transmission structure is used for transmitting loads, and the reinforcing cylinder is arranged outside the thin-wall outer cylinder; wherein the interior of a cavity between the thin-wall outer cylinder and the thin-wall inner cylinder is divided into a plurality of first sealed cabins through a plurality of first cabin dividing plates; a plurality of reinforcing ribs are connected between the thin-wall outer cylinder and the reinforcing cylinder, and the interior of the reinforcing cylinder is divided into a plurality of second sealed cabins through a plurality of second cabin dividing plates. By arranging the conical reducing force transmission structure, the area, affected by stormy waves, of the composite barrel type foundation can be effectively reduced, and the berthing influence of an underwater structure on an operation and maintenance ship can be reduced.
本发明属于海上风机领域，提供了一种无支撑单柱结构的海上风机复合筒型基础，包括：薄壁外筒，设置在薄壁外筒内腔中心位置的薄壁内筒，在薄壁外筒上，用于与风机塔筒连接的单柱过渡段，设置在薄壁外筒和单柱过渡段之间，用于传递载荷的锥形变径传力结构，及设置在薄壁外筒外部的加强筒；其中，薄壁外筒和薄壁内筒之间的空腔内通过多个第一分仓板分隔成多个第一密封舱室；薄壁外筒和加强筒之间连接有多个加强筋，加强筒内通过多个第二分仓板分隔成多个第二密封舱室。通过设置锥形变径传力结构能够有效的减少本发明的复合筒型基础受到风浪影响的面积，并且能够减少水下结构对运维船舶的靠泊影响。
