WAVE ENERGY CONVERSION APPARATUS AND METHOD FOR MANUFACTURING THE SAME

摘要

This invention relates to a wave energy conversion apparatus to be used in relatively shallow water comprising at least: a base (1) arranged to be anchored to the sea bed; an upstanding fin (2) pivotally connected to said base (1), said fin (2) arranged to oscillate in use back and forth about the vertical in response to wave motion acting on faces of the fin (2), and said fin (2) comprising a float part (2b) being sufficiently buoyant in water tending to assist the fin (2) to vertical; and power-take-off (PTO) means (7) for extracting energy from the motion of the fin (2). The conversion apparatus is formed and arranged so that when the base (1) is anchored to the sea bed with the fin (2) facing the wave motion, the fin (2) extends on the low tide vertically from the base (1) through the entire depth of water, and on the high tide the vertical extension of the fin (2) is smaller than the entire depth of water.
