Arrangement in wave energy recovery system

摘要

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.

主权项

1. A wave energy recovery system comprising:
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 device; a connection rod imparting the reciprocating motion of said wing element to said wave energy recovery device; said wave energy recovery device including,
a protective housing having housing walls, anda hydraulic cylinder provided in the protective housing and provided with a piston operably connected to said connection rod for actuation thereby,said housing walls of said protective housing protecting said hydraulic cylinder from exposure to seawater; said connection rod extending through a first housing wall; and a bellows seal surrounding the connection rod as it extends though the first housing wall, the bellows seal sealing the contents of said housing from exposure to said seawater including,
an outer bellows sealingly and fixedly connected at a first end to said connection rod outside said protective housing and at a second end to said first housing wall, andan inner bellows sealingly and fixedly connected at a first end to the connection rod inside said protective housing and at a second end to said first housing.
