Embodiment Construction

[0028] figure 1 Shown is a section of a wind turbine tower 1 consisting of a plurality of connected sections 2 each having a tubular shape. The lower end of the section 2 is formed without a flange. The section 2 is connected to a wind turbine foundation comprising a receiving part formed as a foundation flange 3 . A foundation flange 3 is fixed to the foundation 4 , the cross-section of the foundation flange 3 being T-shaped with a vertical section 5 . Two splice plates 6 , 7 serve as connecting members connecting the flangeless lower end of the section 2 to the vertical section 5 . The sections 2 and vertical sections 5 are provided with radial holes so that the splice plates 6 , 7 can be fixed using bolts and nuts, as indicated by dashed line 10 . In other embodiments, the splice plate may be welded to the section 2 and the vertical section 5 of the foundation flange 3 .

Abstract

A wind turbine installation comprising a wind turbine tower (1, 8, 11, 13, 17, 23, 26) or tower section, a receiving part of a wind turbine foundation installation, connection means suitable for connecting the wind turbine tower (1, 8, 11, 13, 17, 23, 26) or tower section to the receiving part, whereby the lower end of the wind turbine tower (1, 8, 11, 13, 17, 23, 26) or the tower section is flange-less.

Description

technical field [0001] The invention relates to a wind turbine installation comprising a wind turbine tower or tower section, a receiving part of a wind turbine foundation installation and connection means adapted to connect a wind turbine tower or tower section to said receiving part . Background technique [0002] Tubular steel towers for wind turbine installations are large in diameter and weight. Its size makes it difficult to transport the tower to the wind farm. Typically, steel towers for wind turbines are produced in sections in a factory and these sections are transported to the installation site. Towers are generally constructed of a number of segments having a cylindrical or conical shape. [0003] In recent years, larger turbines have been developed which require larger wind turbine towers. Consequently, the diameter of the tower section increases and the tower section becomes longer and heavier. The dimensions of tall towers for large wind turbines have rea...
