<p>PURPOSE: A wind power turbine with convex blades is provided to protect a rotary blade unit by offsetting wind power applied to the convex blades as the incline of the convex blade is opened at a set angle according to the wind strength. CONSTITUTION: A wind power turbine with convex blades comprises a rotary blade unit(1). The rotary blade unit comprises a rotary blade frame(11), a plurality of convex rotary airfoils(12), a rotary shaft unit(13), and a wind power control unit(14). The rotary blade frame is connected to a rotary shaft(3), and comprises a wind receiving blade. As to the convex rotary airfoils, the front side receives much wind power, and the rear side receives little wind power. The rotary shaft unit is connected to the side of the convex rotary airfoil. The rotary shaft unit controls the incline of the convex rotary airfoil. The wind power control unit varies the incline of the convex rotary airfoil at a set angle according to the wind strength. The front side of the convex rotary airfoil is formed into a flat or concave shape. The rear side of the convex rotary airfoil has a concave structure.</p> |
