Embodiment

In conjunction with accompanying drawing the present invention is described partly.

Fig. 1 is a tomograph schematic representation of the present invention.The present invention is made up of paddle 1, oar arm 2, rotor shaft 3 and support 4, and paddle 1 is parallel with rotor shaft 3, is fixedly connected with rotor shaft 3 through oar arm 2, and paddle is to move by the circumference course bearing in the center with the rotor shaft.Paddle 1 is more than two, and oar arm 2 is installed on the paddle 1, and the outside H of paddle 1 is bandy circular arc, and middle part B is the plane, and inboard T bends inwards, and outside H is the arc windward side, the pressure of positive windage when reducing rotation.

Fig. 2 is a sectional view of the present invention.In the paddle facial planes and rotor shaft 3 center lines radially angle c be 0.01 to 30 the degree;

Fig. 3 is the sectional view of paddle of the present invention, and crooked laterally when paddle 1 outside H circular arc, the radially angle a that the end of its arc and circular arc are crossed the center of circle is 0.01 to 30 degree; If the outside of paddle (1) is outwards bending, the angle on angle after the bending and B plane, middle part is equal to or less than 90 degree.

Paddle 1 inboard T is to circle core shaft direction bending, with B plane, paddle 1 middle part be 0.01 to 30 degree for angle b, the change effect of paddle moving direction of afterbody, the wind direction water conservancy diversion of when with the wind moving, holding concurrently.

When distinguished and admirable from right to left when the x axle direction passes through; Paddle outside H circular arc is tangled the promotion wind wheel by wind and is rotated counterclockwise, and distinguished and admirable rear side to the top paddle produces the thrust in the same way to the top paddle; Receive the inboard T water conservancy diversion of facial planes and inclination in the paddle; The rear side of paddle had thrust upwards to the below paddle equally below wind flow to along the x axle direction, produced rotating power in the same way.Therefore on the paddle diverse location, all produce equidirectional power in various degree, and produced maximum power on the window catch.The air of other non-actings passes voluntarily, and neither acting does not form resistance yet.When paddle was installed in the other direction, paddle can be realized turning clockwise.
