<p>PROBLEM TO BE SOLVED: To solve the problem that, in a conventional tidal power generation device, the displacement of a tide becomes minimum in a tide-stop time zone in a high tide and in the vicinity of the lowest tide, thereby, a displacement amount obtained from the time zone is varied, and an output is lowered in the tide-stop time zone particularly.SOLUTION: In the tidal power generation device, at least three pieces of double-end screw-processed rotating shafts are provided, a sea buoyancy body is provided at one of the rotating shafts, a sea-level buoyancy body is provided at another rotating shaft, and a self-weight body is provided at another remaining rotating shaft. The sea buoyancy body, the sea-level buoyancy body and the self-weight body have double-end screw-nut processed regions, respectively, and are continuously connected to the rotating shafts which are double-end screw-processed. The rotating shafts comprise pulley wheel sprockets, respectively, the pulley wheel sprockets are continuously connected to a serial rotation transmission chain, and a generator is driven via the rotation transmission chain.</p> |
