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.
An apparatus relating to a vertical-axle wind turbine comprises upper and lower horizontally disposed wheels, fore eccentric tube spokes, compressible and tensible slide-cantilevers, rear eccentric tension ropes, pairs of dual-rocker trapezoid linkages, inclined flap-blades, and equipoises, in which: The slide-cantilevers each is inserted into respective fore eccentric tube spokes on the upper and lower wheels with a compression spring placed between the fore eccentric block and the inner end of the slide-cantilever, the rear eccentric tension ropes each is connected between the rear eccentric stake and the slide-cantilever, the pairs of dual-rockers trapezoid linkages each are hinged between the upper and lower slide-cantilevers and the upper and lower beams of an upstanding frame to define deflection of the upstanding frame toward both sides of the dual-rockers up to 40 degrees, the declined flap-blades each with its axis on its upper edge hinged slightly inclined across the upstanding frame, and the equipoises each containing a rolling ball in a reverse-arch tube on a crank counter-lever or containing a counter-lever and a counter-arm extends reversely from the upper edge of the flap-blade and the contained angle between counter-lever and counter-arm is adjustable.
