Abstract

PURPOSE:To both efficiently absorb energy and reduce horizontal force to a dolphin affected by a float in a wave energy absorbing device constituted by coupling the float to the dolphin, by applying the specific flat submerged float. CONSTITUTION:A flat submerged float 1, consisting of mutually separated two exposed parts 1a above a surface of water and flat submerged part 1b, is arranged parallelly to the crest line of a wave, and their connecting rods 2 are coupled to energy converter parts 3 provided on dolphins 4, if the floats 1, 1 are vertically moved by the wave, the converter part 3 is actuated to absorb energy. The exposed part 1a above the water surface is formed to block-shaped in narrow width with small resistivity against horizontal wave power to extremely decrease horizontal force affected to the dolphin 4. The flat submerged part 1b is formed to sufficient length and width with large resistivity against vertical movement, and a vertical movement proper period of the whole device is determined so as to be almost coincident with a design wave period, then wave energy can be completely absorbed.
