VERTICAL-AXIS FLUID TURBINE

摘要

The present invention provides a motion-translation mechanism for rotating blades of a vertical-axis wind turbine. Two or more axles are mounted for rotation about the first axis and each having a first end connected to the power shaft and the second end having a blade holder. A surface is mounted circumjacent the power shaft and is axially spaced from the two axles and the shape of the surface defines the path of each of the connector arms as each connector arm assembly rotates radially about the surface while maintaining connection to the blade holder. Each connector arm has a third end and a fourth end opposed to the third end. The third end being connected to its associated blade holder, the fourth end being in cooperative engagement with the surface. Each fourth end moves from a maximum vertical displacement to a minimum vertical displacement then from a minimum vertical displacement to a maximum vertical displacement during a single rotation of the power shaft thus causing the blade holders along with the attached blades to rotate positive 90° then negative 90 degrees about the second axis of rotation.

1. A motion-translation mechanism for rotating blades of a vertical-axis wind turbine comprising:
a power shaft mounted for rotation about a first axis of rotation oriented vertically; two axles mounted for rotation about the first axis, each axle having a second axis of rotation extending longitudinally therethrough and transverse to the first axis, each axle having a first end and a second end opposed to the first end, the first end being connected to the power shaft and the second end having a blade holder; a surface mounted circumjacent the power shaft and axially spaced from the two axles; and two connector arms one of each associated with an axle to define associated axles and associated connector arms, each connector arm having a third end and a fourth end opposed to the third end, the third end being connected to its associated axle, the fourth end being in cooperative engagement with the surface, each fourth end moves between a maximum vertical displacement to a minimum vertical displacement upon a 180° rotation of the power shaft to rotate each of the two axles 90° about the second axis of rotation.
