Abstract:
A vertical-axle wind power machine comprising:a multipurpose turbine framework which comprises a vertical axle and a plurality of radial arms secured to said vertical axle;a plurality of sets of oblique blades respectively mounted on said radial arms of said multipurpose turbine framework, wherein said oblique blades are divided into four wings by a cross coordinate at the support point thereof; along the latitudinal axis the after two wings portioned wider than the fore two wings leaving said two wider wings performing as guide wings and said two narrower wings performing as counterbalancing wings, and along the longitudinal axis the outer wings portioned longer than the inner two wings leaving said two outer wings performing as master wings and said two inner wings performing as counterbalancing wings, is provided with appropriate counterweights in the counterbalancing wings to maintain a balance condition at said support point thereof, is tilted to an adjustable angle below 45 degrees from the radial blade axis upon said radial arm by adjusting the length of stay means jointed between said radial blade axis and said support point thereof, and is defined to swing within a range of 180 degrees between the upstanding and overturned positions thereof by appropriate stop means; anda multiplying transmission comprises a pair of paralleled vertical shafts and pairs of bushed multiplying gears serially coupling between said paralleled vertical shafts to multiply low speed rotary motion transmitted from said vertical axle to high speed rotary motion for an output.
