Abstract

The invention relates to a multi-tube jacket offshore wind turbine foundation, comprising: an upper transition section; a plurality of suction cylinders, arranged below the upper transition section and evenly distributed around the upper transition section; the top of the suction cylinder is the top of the cylinder; The lower transition sections are respectively arranged on the tops of multiple suction cylinders; the lower transition sections include annular plates and ribs arranged on the tops of the cylinders, a plurality of ribs are evenly distributed around the annular plates, and one end of the ribs is connected to the annular plate The outer peripheral side of the jacket is connected; the jacket includes a plurality of main legs; the top of the main legs is connected to the upper transition section, and the bottom end of the main legs is connected to the ring plate on the corresponding lower transition section. When in use, the fan is installed on the upper transition section, and the lower transition section can effectively transfer the load on the main legs of the jacket to the top area of ​​the suction tube effectively, effectively ensuring that the top of the suction tube is stressed evenly, and is not easy to cause damage to the suction tube Suffering from strength damage and fatigue damage is conducive to the long-term safe and stable operation of the suction cylinder.

Description

technical field [0001] The invention relates to the technical field of offshore wind power engineering, in particular to a 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 the s...
