Abstract

The invention relates to a novel multi-cylinder jacket offshore wind turbine foundation which comprises an upper transition section; a plurality of suction cylinders which are arranged below the uppertransition section and are uniformly distributed by taking the upper transition section as the center, wherein the top of each suction cylinder is a cylinder top; a plurality of lower transition sections which are respectively arranged on the top of a plurality of suction cylinders, wherein each lower transition section comprises an annular plate and rib plates which are arranged on the cylindertop, a plurality of rib plates are evenly distributed around the annular plate, and one end of each rib plate is connected with the peripheral side of the annular plate; and a jacket which comprises aplurality of main legs, wherein the top ends of the main legs are connected with the upper transition section, and the bottom ends of the main legs are connected with the annular plates on the corresponding lower transition sections. The wind turbine is mounted on the upper transition section in use and the lower transition sections can effectively and uniformly transmit the load on the main legsof the jacket to the cylinder top area of the suction cylinders so that the cylinder top of the suction cylinders is effectively ensured to be uniformly stressed, the suction cylinder is not liable to be subjected to strength damage and fatigue damage, and the long-term safe and stable operation of the suction cylinder is facilitated.

Description

technical field [0001] The invention relates to the technical field of offshore wind power engineering, in particular to a novel multi-tube jacket offshore wind turbine foundation. Background technique [0002] Wind power is a non-polluting, renewable and clean energy. my country is a country rich in offshore wind resources. Compared with land-based wind power, offshore wind power has higher power generation, more stable operation, and does not occupy land resources. Facing the strong energy demand in developed coastal areas, offshore wind power has huge development potential . With the maturity of offshore wind power technology, high-power wind turbines and deep water areas are the future development direction. [0003] Offshore wind turbines must be supported on the offshore wind turbine foundation. The lower transition section of the multi-tube foundation of the traditional offshore fan is mainly connected with the top of the suction tube through two diagonal braces; at...
