Problems solved by technology

[0002] At present, the towers of most wind turbines are made of circular steel towers. With the increasing power of wind turbines (>5MW), the weight of wind turbines and the length of blades increase accordingly, and the diameter and thickness of towers supporting wind turbines also increase. The continuous increase, for the current domestic situation, the production, transportation and installation of large diameter towers are very difficult
In many cases, when faced with high-power wind turbines, the strength and rigidity of the tower are sufficient, but transportation and installation are very troublesome, and even impossible to transport and install

Embodiment Construction

[0023] Tower structures for wind turbines, such as figure 1 As shown, the fan includes a tower 100, and the upper end of the tower 100 is provided with an impeller 200. The tower 100 is manufactured into several sections of the tower, and each section of the tower does not exceed the transportable size; the bolt method is used between the towers. The blue plate connection, the material of each part of the tower is linear elastic, uniform and isotropic. The tower structure, that is, each section of the tower includes a tower body 1, and a plurality of horizontal reinforcement rings 2 are evenly distributed on the tower body 1; a plurality of vertical reinforcement rings are evenly distributed on the tower body 1. Rib 3, the reinforcing rib and the reinforcing ring are connected by welding.

[0024] The cylindrical tower body 1 is welded by steel, and the reinforcement rib and the reinforcement ring are connected with the tower body 1 by welding. The middle of the tower body 1 ...

Abstract

This invention discloses a tower structure for a blower, which comprises a column-shaped tower body, wherein a plurality of transverse reinforcement rings are evenly distributed on the tower body; a plurality of vertical reinforcement ribs are also evenly distributed on the tower body; the middle of the column-shaped tower body is hollow; and the reinforcement rings and the reinforcement ribs are arranged on the inner wall of the tower body. The tower structure disclosed by this invention has a benefit effect that because a plurality of the transverse reinforcement rings and a plurality of vertical reinforcement ribs are evenly distributed on the tower body, axial loading capacity and transverse loading capacity of a tower can be enhanced so as to ensure a tower body structure not to be buckled or broken; while intensity same as a tower with a large diameter and a large wall thickness is obtained, the diameter and the wall thickness of the tower of a large blower are reduced; construction cost and cost are reduced; and transportation and hoisting are processed conveniently.

Description

【Technical field】 [0001] The invention relates to tower structures for wind turbines. 【Background technique】 [0002] At present, the towers of most wind turbines are made of circular steel towers. With the increasing power of wind turbines (>5MW), the weight of wind turbines and the length of blades increase accordingly, and the diameter and thickness of towers supporting wind turbines also increase. With the continuous increase, it is very difficult to manufacture, transport and install large-diameter towers for the current domestic situation. Most of the time, when faced with high-power wind turbines, the strength and rigidity of the tower are sufficient, but the transportation and installation are very troublesome, or even impossible to transport and install. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a cylindrical tower that reduces the overall buckling damage and local buckling...
