Marine wind turbine having a pylon vertically adjusted by setting

摘要

An off-shore wind turbine with a base supporting a pylon and a wind engine, the wind turbine being characterized in that the said base includes a tubular cavity, a bottom portion of said pylon being fixed in embedded manner inside said tubular cavity using a device that enables the angle of inclination of the axis (ZZ′) of the pylon to be adjusted relative to the axis (Z1Z′1) of the tubular cavity; and the adjustment device includes independent chocking mechanism interposed between the pylon bottom portion and the tubular cavity; and a centering mechanism secured to the pylon bottom portion and/or to the tubular cavity, the centering mechanism being situated inside the tubular cavity below at least some of the chocking mechanism and suitable for holding the point of intersection of the axis (ZZ′) of the pylon bottom portion with the axis (Z1Z′1) of the tubular cavity in a fixed position.

1. An off-shore wind turbine resting on the sea bottom, the wind turbine comprising:
a base having a bottom bearing surface bearing against the ground of the sea bottom; and a pylon supported by said base, the bottom end of the pylon being fixed in embedded manner in said base; and a wind engine supported by said pylon at its top end and comprising a rotary shaft of horizontal axis driven in rotation by an engine and supporting a plurality of blades with said wind engine being coupled to an electricity generator; and said base includes a tubular cavity, a bottom portion of said pylon being fixed inside said tubular cavity, the fixing being performed by means of a device for adjusting the angle of inclination of the axis of said pylon to be adjusted relative to the axis of said tubular cavity; wherein said device for adjusting the angle of inclination of said pylon in said base comprises: a) independent chocking means interposed between said pylon bottom portion and said tubular cavity at the level of the top opening of said tubular cavity projecting above sea level; and b) centering means secured to said pylon bottom portion and to said tubular cavity, said centering means being situated inside said tubular cavity beneath said chocking means, and said centering means comprising a first centering element secured to a bottom wall of said tubular cavity, located at the center thereof and co-operating with a second centering element located at the center of the bottom end of said pylon bottom portion, said centering means being suitable for holding the point of intersection between the axis of said pylon bottom portion and the axis of said tubular cavity in a fixed position at the bottom of said tubular cavity.
