Embodiment Construction
[0038] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0039] Such as figure 1 As shown, the embodiment of the present invention provides a tower for a wind power generation unit. The tower includes a plurality of tower segments 1, and each tower segment 1 has a plurality of grooves 2 and flanges 3 on both sides. A plurality of tower tube segments 1 are connected to form tower tube segments or tower tubes through the connection between the tower tube segment grooves and the flanges.
[0040] Specifically, the plurality of tower tube segments 1 are all arc-shaped in the circumferential direction, and the tower tube segments 1 can be formed by rolling steel plates through a plate rolling machine. A plurality of evenly distributed grooves 2 and flanges 3 are cut on both sides of the tower segment 1, and the grooves 2 on the tower segment are cut in parallel with the flanges 3 on the adjacent tower se...

The invention provides a wind generating set tower drum and a tower drum construction method. The tower drum comprises multiple tower drum divided pieces, grooves and flanges are arranged on the two sides of the tower drum divided pieces, and every two adjacent tower drum divided pieces are fixedly connected. According to the wind generating set tower drum, the tower drum is divided into multiplepieces to be manufactured, the problems of large-diameter tower drum manufacturing and transport limiting are solved, optimized design of the large-diameter tower drum is achieved, the center height of a wind wheel hub can be effectively increased, the weight of the tower drum is reduced, the tower drum is simple in connection structure, the stress characteristics of the wind generating set towerdrum are met, and mounting is convenient; meanwhile, plate strips for connection are equivalent to longitudinal stiffening ribs, and the yield strength is improved to a certain degree.
Description
technical field [0001] The invention relates to the technical field of wind power generation, 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 4.3-4.7 meters; For rolled and welded towers, the maxim...
