Abstract
A foundation device for a wind turbine tower includes a hollow main body with a lower face and an upper face. Both the lower face and the upper face contain a hollow space. Each of the faces include an outer perimeter and an inner perimeter. The main body additionally includes an outer lateral wall disposed between the outer perimeter of the lower face and the outer perimeter of the upper face, and an inner lateral wall between the inner perimeter of the lower face and the inner perimeter of the upper face. The device further includes a plurality of columns that project from the upper face of the main body.
Claims12
A foundation device for a wind turbine tower, the device being configured to be supported on the seabed, comprising:
- a hollow main body comprising:
- a lower face intended for being supported on the seabed;
- an upper face opposite the lower face, wherein the lower face is defined by a surface contained between a first outer perimeter and a first inner perimeter and the upper face is defined by a surface contained between a second outer perimeter and a second inner perimeter;
- an outer lateral wall arranged between the first outer perimeter of the lower face and the second outer perimeter of the upper face;
- and
- an inner lateral wall between the first inner perimeter of the lower face and the second inner perimeter of the upper face;
- a plurality of columns that project from the upper face of the main body;
- the device being characterized in that one of the columns is an anchoring column and presents an anchoring surface configured for receiving the installation of a wind turbine tower, and in that the device further comprises
- a reinforcement ring attached to the anchoring column,
- a plurality of first plates anchored in the reinforcement ring;
- a plurality of second plates adapted to be fixed to a reinforcement ring of a wind turbine tower;
- and
- a plurality of lifting elements, each of which is configured to exert pressure between one of the first plates and one of the second plates.
