Blade positioning hub for wind turbine - has sliding sleeve on hub with guy rods to fold and lock blades

摘要

The hub connection for wind turbine blades (J) allows them to open, close and be detachable. The blades can fold and unfold along the drive axis and can be attached to a cylindrical hub (c) running on a transmission shaft retained by a lock screw. The hub can have tie rods (K) rotating with it and retained on the blades by pivot pins. The blades can be locked in the required position by the tie rods attached to a sleeve on the hub to cause opening and closing of the blades.
