Claim:
A constant direction four quadrant lift type vertical shaft wind power generator, comprising: a truss-type wind wheel, formed by an upper wind disc, a lower wind disc, and supporting rods; a speeder; and a generator, wherein the wind wheel and the speeder are sleeved on a central shaft, several groups of vanes are perpendicularly arranged at a diametral top end of the wind wheel by respective pivots thereof, the wind wheel and the vanes are disposed at an upper end of the wind power generator, and the generator, the speeder, and a controller are disposed at a bottom of the wind power generator, wherein: an overall shape of the vanes is an air-foil shape with equal cross sections; a height of the vanes is equivalent to that of the wind wheel; a shape of the cross section is a circular-arc radius of a head portion that is 1/18- 1/22 of a vane chord length, an arc radius of an outer surface is ⅜ of the chord length, an arc radius of an inner surface is 3/16 of the chord length, a central angle of an overall circular-arc portion is 40-50 degrees, an arch height of a circular arc of the outer surface is ⅕- 1/7 of the chord length, and an arch height of a circle chord of the inner surface is 1/10- 1/14 of the chord length; a back portion of each of the vanes is a linear intersection between the outer surface and the inner surface; and the pivots of the vanes are located at positions 1/7-⅙ of the chord length from the head portion.
