Fluid driven vertical axis turbine

摘要

A fluid turbine comprises a rotor rotatable in use about an axis transverse to the direction of fluid flow, the rotor having a first part carrying a plurality of arcuate blades that may be arranged selectably in compact straight shapes or in arcuate shapes and a second part journalled in a base structure by two or more bearings. Another aspect of the invention discloses an installation frame, devised to support the turbine or other elongated structures in a folded arrangement for transportation on a trailer, and to support assembly and erection thereof.

主权项

1. A fluid turbine comprising:
a rotor rotatable about an axis disposed in use substantially transverse to the direction of fluid flow; a plurality of arcuate blades connected at their opposite ends to the rotor; wherein at least one blade is formed of at least three segments coupled by joints, at least two of the joints being articulated for permitting the mutual inclination of an associated pair of adjacent segments to be varied while the ends of the blade are coupled to the rotor; wherein at least one of the joints comprises a locking mechanism capable of selectably locking the joint in at least one position, thereby locking the associated pair of adjacent segments in at least one predetermined mutual inclination.
