Wave energy absorber of the oscillating water column type

摘要

A wave power generating apparatus is provided with a plurality of L-shaped ducts and floats. The ducts are composed of vertical and horizontal ducts. The vertical ducts each have an air chamber thereon where an impulse turbine and an electric power generator are installed. Each float has a vertical square pillar and a vertical rear half cylinder attached thereto, and is fixedly attached onto the horizontal duct. The apparatus has high efficiency to convert wave power to electric power and needs low mooring force to keep the apparatus on an offshore. <IMAGE>
