Wind energy plant tower

Abstract

A wind energy plant tower with a load-bearing tower wall, which has a circulating outer periphery and consists of a plurality of wall sections, which each one have one centre section and two border sections running in the longitudinal direction of the tower, which are provided with a plurality of connection bores, wherein the surfaces defined by the border sections run along the outer periphery or in a constant distance to the same, and the connection bores are aligned transversely to the outer periphery.

Even the cost for the production, the transportation and the installation of the towers come more and more into the focus of attention. In order to cope with this situation, towers for wind energy plants are known in the state of the art, which are subdivided into plural tower segme...

AI Technical Summary

Benefits of technology

[0009]The wall sections form each one a separate structural component at a time and are connected to each other via the connection bores when the tower is installed. The wall sections are made of metal, preferably steel. The border sections with the connection bores define each at a time a surface which runs along the outer periphery of the tower wall or in a constant distance to it. Thus, the border sections are not realised as flanges which project out of the surface formed by the tower wall like in the state of the art. In particular, the border sections are not more offset against the centre sections than is preset by the desired outer periphery of the tower wall. Instead, the border sections form a uniform lateral continuation of the centre sections. Thus, the border sections run “parallel” to the outer periphery, i.e. they can run immediately along the periphery and form the same, or offset to the outer periphery. Through this, it is achieved that the border sections form an integral constituent part of the wall sections and the tower wall. Furthermore, the production of the wall sections is significantly simplified, because the wall sections do not have to be provided with a flange. Furthermore, the wall sections become more compact because there are no parts projecting out of the surface and through this, they can be transported more simply, as the case may be. The danger to damage a flange in the transportation is reduced.

[0026]According to a further embodiment, the border sections of a wall section extend across the whole length of the wall section in the longitudinal direction of the tower. In principle, the border sections can also be formed only sectionwise. However, the extension across the whole length of the wall sections simplifies the manufacture of the wall sections and results in a more uniform connection with higher staunchness between the neighbouring wall sections.

Problems solved by technology

With the increasing power capacity and magnitude of wind energy plants, the transportation and the installation of the towers impose ever-increasing problems for the wind energy plant operators.
