Method for establishing large floating type wind power station tower drum

Abstract

The invention discloses a method for establishing a large floating type wind power station tower drum. The tower drum comprises a bottom drum joint, a middle drum joint and a top drum joint and is formed by welding the three parts in sequence. The middle drum joint is formed by welding a plurality of same middle barrel joint annular sections in sequence. The top drum joint is formed by connecting a plurality of same top barrel joint annular sections in sequence. By means of the method, the establishing period can be greatly shortened, the establishing difficulty is obviously lowered, the establishing precision is obviously improved, and economical benefits and social benefits are very impressive.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method of a tower of a large-scale floating wind power station, and belongs to the technical field of electric power equipment. Background technique [0002] Non-renewable energy sources such as coal, natural gas, oil, and nuclear energy are the main forms of energy supply in the world at present, but the environmental pollution (air pollution, nuclear residue radiation pollution, etc.) they bring is not optimistic. As a clean and renewable green energy, wind energy has high development efficiency, good economy, large-scale development conditions and commercialization prospects, and it has attracted more and more attention from all over the world. With the development of the global economy, the wind energy market has also developed rapidly. In recent years, the world wind energy market has been growing at a rate of 40% every year. It is estimated that in the next 20-25 ye...

AI Technical Summary

Problems solved by technology

[0011] 1) This processing method is labor-intensive, with long construction period and poor precision;

[0012] 2) The production site of the tower is seriously occupied during the production process;

[0013] 3) Since a large number of circular welds are completed by manual welding, the welding quality is difficult to control;

[0014] 4) It is difficult to guarantee the manufacturing accuracy of the internal reinforcement components and the concentricity of the outer plate of the tower;

[0015] 5) A single tower section needs to be hoisted and turned over multiple times during the construction process
