TOWER SECTION FOR AUTOMATIC LIFTING OF NEW OR EXISTING WIND TURBINES AND AUTOMATIC WIND TURBINE TOWER SECTION METHOD ON THE TOP

摘要

The present invention relates to a tower section and a method of automatically raising said section with new or existing wind turbines on its top, wherein the assembly is raised to heights of more than 120 meters by means of a automatic lifting system that operates at ground level and gradually inserts modules through the bottom. the modules have heights of 10 to 14 meters and are formed by a lattice with at least three vertical columns (5) and diagonal elements (6) that react to torsional moments and wind forces. a transition part (7) with a base (d2) sufficient for lifting with wind conditions of more than 15 m / s is arranged over the modules. The lifting method has several steps, such as: foundation production and installation (12); mounting the transition part (7) on a connecting element (15) of a shoe; wind turbine assembly complete with tubular tower (1),nacelle (2) and its rotor (3); installing a lifting system (10) and connecting structures (14) on a shoe connecting element (16); elevation of a module n; assembly of the different modules; and,Lastly, final module assembly and removal of the automatic lifting system.
