Title:
WAVE-POWER GENERATION SYSTEM, AND TRANSMISSION BODY AND ROTATION CONVERSION UNIT USED THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/045055
Kind Code:
A1
Abstract:
Provided are a wave-power generation system that is durable even when exposed to rainstorms, has an extremely simple structure, and achieves high power generation efficiency, a transmission body that makes a rotary power generator less susceptible to slipping, and a rotation conversion unit that is suitable for said transmission body. Relative vertical movements of a buoy to an underwater movement inhibiting body are converted into vertical movements of a thin and long rope-like transmission body by using a weight (7) and the transmission body in order to cause a rotary power generator to operate, said buoy being set afloat on the sea or lake with high waves so as to move up and down with the heaving of waves, and said underwater movement inhibiting body being capable of remaining substantially stationary in water or at the bottom of water (bottom of the sea, for example) by means of resistance of water (underwater suspension type) or its own weight (bottom installation type). In addition, the transmission body is equipped with guides in order to prevent a rotation conversion unit of the power generator and the transmission body from detaching from each other even in raging waves, and periodic recesses and protrusions are formed on both the rotation conversion unit and transmission body in order to reduce slipping therebetween.
