Problems solved by technology

This deformation may cause handling or assembly problems during installation
On the other hand, in the case of subdivision into a large number of small housing segments, the number of threaded connections produced will be very large, increasing assembly costs as well as maintenance costs for retightening the screws

Embodiment Construction

[0025] As shown in the figures, the tower 1 of a wind power plant 2 is constructed from a lower part 1.1 in the form of a lattice or truss tower and an upper part 1.2 in the form of a tubular tower with a circular cross-section.

[0026] Mounted on the upper end of the tubular tower 1.2 is a wind power plant (wind energy plant) 2 mounted so as to be able to rotate about an axis extending substantially vertically. The wind power installation 2 comprises a rotor 2.1 with rotor blades 2.2, which are preferably rotatable about their respective longitudinal axes and thus adjustable in an infinitely variable manner, and a generator arranged in a nacelle casing 2.3 , the shaft of the generator is connected to the rotor 2.1 for common rotation via a transmission mechanism and a clutch.

[0027] In the exemplary embodiment shown here, the lattice or truss tower 1.1 has six corner bars 1.10. However, it is also possible to have more or less than 6 corner bars. In either case there are...

Abstract

The invention relates to a tower (1) for a wind power plant, having a lower part (1.1) in the form of a lattice tower or trussed tower having at least two corner legs, and an upper part (1.2) in the form of a tubular tower substantially round in cross-section, wherein each corner leg (1.10) is composed of a plurality of steel tube profiles (1.11, 1.12) connected to one another in the longitudinal direction. In order to achieve good transportability and simplified assembly of the components of such a tower, the invention provides a modular tower concept. According to the invention, each corner leg (1.10) is composed of at least three steel tube profiles (1.11, 1.12) which are furnished with perforated flanges (1.13) for receiving bolts, wherein the corner legs (1.10) are connected to one another by struts (1.15) and / or tie bars (1.17) connected at the flanges (1.13), and wherein the steel tube profiles (1.11, 1.12) of each corner leg (1.10) are spiral seam-welded steel tube profiles.

Description

technical field [0001] The invention relates to a tower for a wind power installation having a lower part in the form of a lattice or truss tower with at least two corner bars and an upper part in the form of a tubular tower with a substantially circular cross-section, wherein each individual corner bar is made of It is assembled from multiple steel pipe profiles connected together in the longitudinal direction. Background technique [0002] The development of inland installed wind power plants is leading to higher hub heights of over 100 meters in order to take advantage of greater and more constant wind speeds and thereby improve the efficiency of these wind power plants. However, taller tubular towers with larger and stronger rotors and generators simultaneously require increased wall thicknesses and diameters of tower sections in order to meet the resulting greater structural mechanical requirements such as stiffness, buckling resistance and fatigue strength. However, t...
