<P>PROBLEM TO BE SOLVED: To provide an ocean current and tidal current wave power generation system which can sensitively and optimally respond to complicated motions of ocean currents and tidal currents in a wide range and has a large size and outputs high power with high efficiency and is economical. <P>SOLUTION: Rotary disks 11, 12 are mounted with a large number of current-receiving blades 3 which have faces in a vertical direction and are arranged in a passive variable pitch or a fixed pitch of a lifting force generation type or an active variable pitch. The rotary disks are installed in a horizontal direction near the water surface or tethered to float, and made to rotate by acquiring a propelling force in the same direction from motions of ocean currents and tidal currents as an energy source, and thereby, energy is absorbed from the rotation. By mounting a large number of current-receiving blades on segmented positions, it is possible to respond with an independent and optimal form in each segment to a water flow that always changes in accordance with the motion directions and flow velocities of ocean currents and tidal currents and influences of other blades, and as the whole apparatus, a current receiving cross-sectional area with respect to ocean currents and tidal currents can be increased in size and the structure can be simplified. <P>COPYRIGHT: (C)2013,JPO&INPIT |
