Abstract

The invention discloses an epoxy resin carbon steel concrete composite stand column for a marine environment. The epoxy resin carbon steel concrete composite stand column comprises a core concrete column, a carbon steel tube and an epoxy resin tube. Compared with components of a supporting structure of an existing offshore wind turbine, the epoxy resin carbon steel concrete composite stand column can effectively relieve vortex-induced vibration in an ocean, and has the advantages of being economical and capable of resisting corrosion.

Description

technical field [0001] The invention belongs to offshore wind power generation equipment technology Liang Yu, and in particular relates to an epoxy resin carbon steel concrete composite column used in the marine environment. 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 ...
