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

摘要

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 (2), a set of wings (3a) fastened to a support means (6) that is hinged at its lower ends onto the body (2) to make a reciprocating motion in response to kinetic energy of waves or tidal cur- rents, and a power-take-off (PTO) means (3b). The arrangement comprises at least adjustment means (12) capable to adjust the total effective surface area of the wings (3a).
