Vertical axis wind turbine

摘要

To a rotor supporting plate (1) by means of upper bearings (+2'1a, +2"1a, ..., +2'1b, +2"1b, ...) and lower bearings (-2'1a, -2"1a, ..., -2'1b, -2"1b, ...), which are fastened to the said rotor supporting plate (1) below the said upper bearings (+2'1a, +2"1a, ..., +2'1b, +2"1b, ...), there are pivotally attached upper axles (+2', +2", ...) and lower axles (-2', -2", ...), pertaining to the said bearings and circularly evenly mutually spaced above and below, respectively, a middle point of the said rotor supporting plate (1), to which said upper axles (+2', +2", ...) and said lower axles (-2', -2", ...) respective upper half-vanes (+3'a, +3"a, ..., +3'b, +3"b, ...) and lower half-vanes (-3'a, -3"a, ..., -3'b, -3"b, ...) are fastened. Two by two half-vanes are fastened to the common axle so that the pairs are displaced for 90° to each other. Upper and lower catching gears (+2'2a, +2'2b; +2"2a, +2"2b; ...; -2'2a, -2'2b; -2"2a, -2"2b; ...) are mounted to the ends of each respective upper axle and lower axle in such a way that the catching gears mesh each other in pairs. The rotor supporting plate (1) remains permanently a plane of symmetry of the upper and lower half-vanes.

The rotor of the invention is distinguished in that the mutual relative position of two half-vanes to each other is automatically adapted according to their current velocity with respect to the wind velocity, i.e. when moving towards the wind they close so that their air resistance is reduced.
