Wave energy recovery apparatus with power-take-off arrangement

Wave energy recovery apparatus with a power-take-off arrangement comprising at least a base, a reciprocating panel, two power-take-off (PTO) units with each PTO unit comprising one or more generators to convert kinetic energy of waves or tidal currents to electricity, at least two gear transmissions and at least two one-way clutch mechanisms where the gear transmissions and one-way clutch mechanisms are operatively connected between the panel and the generators, wherein the panel is arranged to rotate a half of the generators when the panel is rotating into one direction and another half of the generators when the panel is rotating into the opposite direction, wherein the apparatus comprises a hinged tubular shaft that is fastened to the lower edge of the panel and is arranged to rotate along with the panel, and the apparatus comprises two or more PTO units coupled to the tubular shaft, each PTO unit comprising a similar group of generators, a gear transmission for its generators and a one-way clutch mechanism operatively connected between the tubular shaft and the gear transmission.
