WAVE-POWER GENERATION SYSTEM, AND TRANSMISSION BODY AND ROTATION CONVERSION UNIT USED THEREFOR

摘要

A wave activated electric power generating system is disclosed that is durable even if it is exposed to a rainstorm, extremely simple in structure and highly efficient in power generation. A motion transfer medium rendering the rotary part of an electric generator less liable to produce slipping and a rotation transform member adapted to rotate while fitting with the motion transfer medium in movement are also provided. The system includes a buoy floating on the sea or a lake where waves are high so as to move up and down with an undulation of the waves, and an underwater motion restrainer that is suspended underwater by water resistance (underwater suspension type), or alternatively submerged by its own weight on a floor of the sea or lake (bottom of water installation type), to lie substantially at a standstill. Vertical up and down movement of the buoy relative to the underwater motion restrainer is converted and transferred by the motion transfer medium in the form of an elongate rope vertically moving under the weight of a weight element 7 to operate the rotary electric generator securely connected to the buoy. The system is provided with a guide means which ensures that the rotation transform member for the electric generator and the motion transfer medium may not come off each other even under raging waves. So that they may not slip from each other, the motion transfer medium and the rotation transform member are each formed thereon periodically with a corrugation.
