POWER GENERATION DEVICE UTILIZING TIDE LEVEL DIFFERENCE AND POWER GENERATION METHOD

摘要

PURPOSE:To generate power by utilizing vertical motion of a pair of floats XY caused by the change in tidal level and smoothly drive a power generation device even when the tide is changing between the ebb and flood at very small change in tidal level. CONSTITUTION:A pair of floats XY 1, 2 are moved vertically in a water tank 3. A power generator is driven by transducing devices 4, 5, 6 which transduce the above linear motion to rotary motion through a speed conversion device, for generating power. When change of the tide is small, a solenoid valve 8 between the side of sea and the water tank 3 is closed. The level inside the water tank 3 is adjusted by opening and closing solenoid valves 12, 13 of a level water tank 11 provided separately from the water tank 3.
