Abstract

The invention discloses a stainless-steel-concrete composite column used in the marine environment. The composite column comprises a core concrete column, a stainless steel tube and a stainless steel sheet. Compared with an existing offshore wind turbine supporting structure component, the composite column can effectively alleviate vortex-induced vibration in the ocean, and has the advantages of being economical and corrosion-resistant.

Description

technical field [0001] The invention belongs to offshore wind power generation equipment technology Liang Yu, and in particular relates to a stainless steel concrete composite column used in marine environments. Background technique [0002] As a clean and renewable energy, wind energy is getting more and more attention from all over the world. In the past ten years, the annual growth rate of wind power installed capacity in the world has been 20%-30%, and the world wind power is developing at a rapid speed. Under the guidance of national policies, my country's offshore wind power has also been widely used and developed, and its total installed capacity ranks first in the world. At present, most offshore wind turbines are deployed in shallow waters near the coast. However, the supporting structures of most offshore wind turbines will be in the harsh marine environment for a long time, and will be subjected to complex sea, wave, current and other effects. The long-term per...
