Abstract

The invention discloses a wind power mixing tower barrel based on an edge stiffening combined shell, and relates to the technical field of wind power generation. The upper portion of the wind power mixing tower barrel is a pure steel tower barrel, and the lower portion of the wind power mixing tower barrel is a combined tower barrel. The combined tower barrel is formed by splicing two to eight edge stiffening combined shells along the circumferential direction, and is assembled along the vertical section. The edge stiffening combined shell is composed of hollow interlayer steel tube concrete and outer end plates, inner end plates and stiffening plates arranged along the periphery of the hollow interlayer steel tube concrete. The hollow interlayer steel tube concrete is composed of an outerlayer steel tube, an inner layer steel tube and concrete. Bolts, steel angles, T-shaped steel parts or a combination of the three steel parts are welded on one side of the steel pipe in advance, andthen concrete is poured. According to the wind power mixing tower barrel, the advantages of the combined structure are brought into full play, the stress form is reasonable, the connection is reliable, all the components can be prefabricated in advance and assemblied in filed, the construction efficiency is high, the material consumption is saved, the transport is convenient, and the engineering application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of wind power generation. Background technique [0002] Wind power is a non-polluting, renewable and clean energy. Wind farms have high power generation, stable wind turbine operation, and mature manufacturing technology, and have been widely used in recent years. [0003] With the increasing demand for wind power energy, high-power, high-tower wind turbines are becoming more and more mainstream. Traditional wind turbines mostly use pure steel towers. In order to meet the requirements of stability, strength and fatigue, the diameter and wall thickness of the towers are generally large, resulting in waste of materials, difficult construction and inconvenient transportation. Therefore, it is necessary to develop and research a new hybrid tower form that is safe, reliable, convenient for construction and transportation, and saves cost. Contents of the invention [0004] The invention proposes a wind power ...
