1. 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.
