<p>PURPOSE: A rotation device for water power or wind power generation having a plurality of inclined rotary shafts is provided to minimize resistances by wind power with reducing a drag area. CONSTITUTION: A rotation device for water power or wind power generation having a plurality of inclined rotary shafts comprises a first and second rotary shafts, a shaft connector(20), a first and second wing supporting bars, a first wing, and a second wing. The first and second rotary shafts cross each other at an obtuse angle. The shaft connector is installed at a contact point of end parts of the first and second rotary shafts in order to transfer rotations of the first and second rotary shafts each other. A plurality of the first wing supporting bars is installed on a periphery of the first rotary shaft at constant intervals, and radially extended to an outside direction from a center of the first rotary shaft. The second wing supporting bars are installed on the periphery of the second rotary shaft at the constant intervals, and radially extended to the outside direction from the center of the second rotary shaft. The first and second wings are installed on each end part of the first and second wing supporting bars.</p> |
