Abstract
The present invention provides a wind generator tower and a process for assembly thereof. A truncated conical tower assembled from reinforced concrete modules disposes of a tensioning system which provides greater resistance to the same and, in turn, the joints defined between the modules which form the tower are sealed.
Claims20
A wind turbine tower defined by a surface of revolution, the wind turbine tower being tapered upwardly and comprising:
- at least one annular section composed of at least four modules that join together to form the at least one annular section, wherein the at least four modules respectively dispose of an upper horizontal side, a lower horizontal side and a first lateral side and a second lateral side, each side comprising a beginning endpoint and an ending endpoint, wherein for at least two of the modules of the at least one annular section:
- at least a portion of the first lateral side and at least an opposing portion of the second lateral side are parallel and directly adjacent to the lower horizontal side, and
- the upper horizontal side is shorter than the lower horizontal side.
A method for assembling a wind turbine tower, the tower being tapered upwardly, the method comprising:
- providing at least one annular section composed of at least four modules that join together to form the at least one annular section, wherein the at least four modules respectively dispose of an upper horizontal side, a lower horizontal side and a first lateral side and a second lateral side, wherein for at least two of the modules of the at least one annular section:
- at least a portion of the first lateral side and at least an opposing portion of the second lateral side are parallel and directly adjacent to the lower horizontal side, and
- the upper horizontal side is shorter than the lower horizontal side;
- and
- inserting, using a guiding means incorporated in the vertical sides of the modules, a first module by a movement at least partially vertical between a second module and a third module.
