Vertical wind energy converter with variable diameter for wind power stations

摘要

The vertical wind energy converter has articulated rods (2; 3) which connect the axis of rotation (4) to the rotor blades (1). This arrangement allows the diameter of the rotor to be varied. The varying of the diameter of the rotor occurs automatically due to the centrifugal force of the rotor blades, controlled by a pivoted adjusting weight (6) moving along the axis of rotation so that the rotor produces an optimum torque in the starting phase. In high winds the adjusting weight (6) on a cable (15) can be lowered by way of a cable winch (17; 18) so that the diameter of the rotor becomes smaller and thereby storm-proof. IMAGE
