This invention relates to an arrangement in a wave energy recovery apparatus and to a method for operating the wave energy recovery apparatus. The apparatus comprises at least a base (), on which a reciprocating panel () is installed, a pivot shaft () for the reciprocating panel (), a control system, and one or more power-take-off (PTO) units () to convert kinetic energy of waves or tidal currents to another type of energy. The arrangement comprises adjustment means () to set the top of the panel () in its vertical position to approximately correspond to the altitude of the surface () of the water.

Arrangement in a wave energy recovery apparatus and method for operating a wave energy recovery apparatus

This invention relates to a wave energy recovery apparatus with an energy transfer arrangement comprising at least a base, a reciprocating panel, a pivot shaft for the reciprocating panel, a control system, and a driving and power-take-off (PTO) arrangement equipped with an actuating mechanism (), and one or more power-take-off (PTO) units to convert kinetic energy of waves or tidal currents to another type of energy, each PTO unit comprising a hydraulic power transmission mechanism having hydraulic cylinders with pistons inside the hydraulic cylinders. The pistons are fastened with their free ends to the common connecting plate that is arranged to move all the pistons simultaneously inwards into the hydraulic cylinders and to draw all the pistons simultaneously outwards from the hydraulic cylinders.

Wave energy recovery apparatus with an energy transfer arrangement

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.

Energy transfer arrangement of a wave energy recovery apparatus

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. The arrangement comprises at least a surface level follow-up means capable to change the vertical position of the upper edge of the reciprocating panel element along with the change of the vertical position of the surface level caused by a tidal fluctuation.

Surface level follow-up arrangement for a wave energy re-covery system

This invention relates to an arrangement for a surface area adjustment of a reciprocating wing system in a wave energy recovery system where the wave energy recovery system comprises at least a body, a set of wings fastened to a support means that is hinged at its lower ends onto the body to make a reciprocating motion in response to kinetic energy of waves or tidal currents, and a power-take-off means. The arrangement comprises at least adjustment means capable to adjust the total effective surface area of the wings.

Arrangement for a surface area adjustment of a reciprocating wing system in a wave energy recovery system

This invention relates to an arrangement in a wave energy recovery system comprising at least a wing element hinged on its one edge to make a reciprocating motion in response to kinetic energy of waves or tidal currents, a wave energy recovery means having a space alterable by its volume with the help of a connection rod making a reciprocating movement caused by the wing element At least the sealings and/or through holes between the space and the connection rod are protected against seawater.

Arrangement in wave energy recovery system

The object of the invention is a method for installing and servicing an apparatus module recovering the kinetic energy of water; and the apparatus module itself. The apparatus module with wave energy recovering units is descended into the sea bottom and is kept steady at the sea bottom by the help of its own mass and the mass of the water filled into a plurality of soft and hard compartments and valve compartments in the body of the apparatus module. Correspondingly the apparatus module is lifted into the surface of the water and made floating by the help of air that is blown to the plurality of soft and hard compartments and the valve compartments in order to replace the water.
