The utility model overcomes the defects in the prior art, and provides the vertical-axis wind power blade, which greatly reduces the influence of the headwind surface on vertical-axis wind power generation by reducing the wind area of the headwind surface, increasing the moment of force of the windward surface and guiding part of wind of the headwind surface into the windward surface for use; in order to solve the technical problem, the technical scheme adopted by the utility model is as follows: a plurality of blades are annularly and uniformly arranged around a rotating mechanism which vertically rotates, and each blade comprises a first arc-shaped part and a second arc-shaped part which are different in curvature radius, the curvature radius of the first arc-shaped part is larger than that of the second arc-shaped part, the first arc-shaped part and the second arc-shaped part are vertically arranged, one end of the first arc-shaped part is connected with a rotating mechanism, the other end of the first arc
