Patent ID: 7094017

Claim:
A vertical shaft driving device, comprising: four rotary blades arranged in a circumferential direction of a central shaft and capable of orbital motion integrally with said central shaft, and a line extended from a blade face of each rotary blade intersects a blade face of an adjacent rotary blade at a right angle; a cylinder section, in which a rotor having said central shaft and said rotary blades can be rotated; a fixed vane section being provided to enclose said cylinder section, said fixed vane section having a plurality of guide vanes, which are arranged in the circumferential direction at regular intervals so as to straighten air or water flows and introduce them to said rotary blades; and a plurality of arms, which are radially extended from said central shaft at regular angular intervals, said arms being rotated together with said central shaft, wherein the blade faces of the blades diagonally intersect the radial lines from said central shaft at an angle of 30–45 degrees so collide the air or water flows collide sequentially with multiple blades of the four rotary blades.
