Problems solved by technology

A disadvantage of the known towers is that, as the height of the wind turbine increases and the diameter of the turbine blades increases as the loads caused by the horizontal forces on the turbine blades increase, the diameter of the tower bottom has to be increased such that the path of the tower bottom parts Transport becomes impossible diameter
This results in the need to assemble these bottom parts at the construction site, resulting in additional cost and loss of quality

Embodiment Construction

[0024] figure 1 A wind turbine 1 is shown with a blade 2 which is rotatable about a substantially horizontal axis of rotation. Bearings supporting the rotating shaft and blades 2 are mounted in a nacelle 3 mounted on top of a tower 6 . A base 11 supports the tower 6 and a bearing 10 between the base 11 and the tower 6 makes it possible to turn the tower 6 so that the blades 2 can face the wind. A support ring 4 surrounds the tower 6 at approximately half the height between the nacelle 3 and the ground and holds the tower 6 in an upright position. In the embodiment shown, four feet 5 support the support ring 4 and position the support ring 4 approximately at half the height of the housing 3, preferably at a height between one-third and two-thirds of the height of the housing 3 . In other embodiments, the number of legs 5 may be three or five or more.

[0025] The leg support 7 supports and holds the lower end of a leg 5 whose upper end is fixed to the support ring 4 . The ...

Abstract

The invention concerns a tower for a wind turbine which tower supports a nacelle with bearings in which a horizontal rotation axis with blades can rotate, the tower comprises a steel wall of circular section, a drive for rotating the nacelle around a vertical axis of the circular section and at the bottom of the tower foundation means for supporting the tower in upright position. In accordance with the invention the foundation means comprises a bearing on a base which bearing supports the tower and a support ring positioned by three or more legs above the base for keeping the tower upright wherein in the support ring rollers or wheels press against the steel wall of circular section.

Description

Background technique [0001] The invention relates to a tower for a wind turbine according to the preamble of claim 1 . Such towers are generally cylindrical or slightly conical with a closed periphery and are often used because they are easy to manufacture and have limited maintenance costs, since they can be painted efficiently. A disadvantage of known towers is that, as the height of the wind turbine increases and the diameter of the turbine blades increases as the loads caused by the horizontal forces on the turbine blades increase, the diameter of the tower bottom has to be increased such that the path of the tower bottom parts Transport becomes impossible diameter. This results in the need to assemble these bottom parts at the construction site, resulting in additional costs and loss of quality. Contents of the invention [0002] In order to overcome this disadvantage, the tower is according to claim 1 . By adding support rings around the tower, horizontal forces on ...
