Abstract: This invention relates to an energy transfer arrangement of a wave energy recovery apparatus comprising at least a base, a reciprocating panel, supporting legs and a pivot shaft for the reciprocating panel, and a driving and power-take-off arrangement equipped with an actuating mechanism and one or more power-take-off units to convert kinetic energy of waves or tidal currents to another type of energy, each PTO unit comprising a power transmission mechanism. The actuating mechanism is arranged to transfer the reciprocating motion of the panel mechanically to a linear motion of the power transmission mechanism of each PTO unit.

Abstract: This invention relates to a surface level follow-up arrangement for a wave energy recovery unit where the wave energy recovery unit comprises at least a panel element hinged at its lower edge onto the base at the bottom of the sea with the help of one or more support structures and one or more support shafts to make a reciprocating motion in response to kinetic energy of waves or tidal currents.
