ABSTRACT:
An apparatus relating to a vertical-axle wind turbine comprises fore eccentric compressible and tensible slide-cantilevers, rear eccentric tensible ropes, dual-rocker trapezoid linkages, slightly inclined flap-blades, and counter-lever with equipoises. Accordingly, all blades on the wind turbine can catch favorable wind force at optimum leeway about 260 degrees each rotation; can absorb centrifugal, centripetal and circumferential shocks from gusts and variable wind force and convert the same to the same direction of torque; can adjust their radius against variable wind speed to stabalize the rotary speed; and can release resistance from relative wind sensitively and streamlined within the remaining 100 degrees of the rotation under the control of respective dual-rocker trapezoid linkages and equipoises to drive the apparatus for converting wind force to mechanical power most efficiently for commitment.
