Problems solved by technology

[0003] At present, steel tubular towers are mainly limited by the following aspects: transportation conditions, especially when used for land transportation, due to the influence of obstacles such as bridge holes, the maximum diameter of the tower is 4.3 to 4.5 meters; For rolled and welded towers, the maximum wall thickness of the coiled plate in the tower factory is about 80mm. However, using traditional steel tubular tower technolog

Abstract

The invention provides a tower drum of a wind generating set and a construction method of the tower drum. The tower drum comprises tower drum arc-shaped fragments, long-strip-shaped connecting portions and arc-shaped connecting portions. The long-strip-shaped connecting portions are fixed along the two sides of the tower drum arc-shaped fragments, and the arc-shaped connecting portions are fixed along the bottom edges and top edges of the tower drum arc-shaped fragments. The long-strip-shaped connecting portions and the arc-shaped connecting portions are each provided with a plurality of connecting holes. The cross section of each long-strip-shaped connecting portion is in an L shape, first folded edges are arranged on the outer side edges of the long-strip-shaped connecting portions, and second folded edges of preset height are arranged on the outer arc edges of the arc-shaped connecting portions. The tower drum arc-shaped fragments are spliced and fixed in the circumferential direction to form the tower drum or at least two tower drum segments. By means of the tower drum of the wind generating set and the construction method of the tower drum, the problem that land transportation of a large-diameter tower drum is limited is solved, a manufacturing method is mature, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to wind power generation technology, in particular to a tower of a wind power generating set and a construction method of the tower. Background technique [0002] With the increasing capacity of wind turbines and the urgency of using high-altitude wind energy in areas with large wind shear changes, wind turbine towers with a height greater than 100 meters are increasingly favored by the market. In order to realize the requirement of building and using a high tower, and to increase the stability of the high tower, the diameter of the bottom of the tower needs to be made larger and larger to obtain an optimal effect. [0003] At present, steel tubular towers are mainly limited by the following aspects: transportation conditions, especially when used for land transportation, due to the influence of obstacles such as bridge holes, the maximum diameter of the tower is 4.3 to 4.5 meters; For rolled and welded towers, the maximum wall t...
