Abstract
A wind turbine for mounting on an existing industrial chimney (1), tower or the like, includes two vertically aligned blades (3) mounted on rotor arms (2) for rotation about the longitudinal axis of the chimney, tower or the like. The rotor arms are supported from an annular structure (8) secured to the outer circumference of the chimney, tower or the like and include at their radially innermost ends a rotor arm ring (11) which cooperates with the annular support structure to enable the rotor arms and blades to rotate about the chimney, tower or the like under the influence of wind pressure. Drive ring (16) carried by one or each rotor arm (2) are connectable to gearing of one or more power generators (9) positioned within or extended to the chimney, tower or the like.
Claims2
A vertical axis wind turbine in combination with an existing industrial tower on which it is mounted, the wind turbine comprising:
- an annular turbine module secured to the circumference of the industrial tower and comprising drive means connected via gearing to a generator and a steel lattice framework which supports at its outermost end opposed annular guideways;
- two horizontally aligned rotor arms supported by the turbine module and connected to the drive means thereof, the rotor arms carrying bearing members, the bearing members tracking in the opposed annular guideways of the module;
- two vertically aligned blades of fixed geometry secured one to the outermost end of each horizontally aligned rotor arm;
- and
- means carried by each rotor arm at its innermost end for mounting the rotor arm on the turbine module, said mounting means being connected to said drive means to enable the rotor arms and blades supported thereby to rotate about the industrial tower under the influence of wind pressure.
