Tension leg offshore floating type wind driven generator base

The invention discloses a kind of tension leg offshore floating type wind driven generator base, including for providing buoyancy and supporting the bottom supporting floating body of wind power generating set, described bottom supporting floating body bottom is provided with ballast tank；The ballast tank arranged just beneath has at least one piece of damping sheet, described damping sheet and ballast tank to be connected as a single entity by truss structure；There are an at least three coupled hollow floating bodies around the vertical centerline of floating blower foundation is circumferentially disposed, each hollow floating body slopes inwardly relative to the vertical centerline of floating blower foundation from lower end towards upper end；And each hollow floating body is connected to the piled anchor in seabed with fixed to seabed by tension leg.
