A wave electrical power plant with a float connected by a cable to a linear generator via a parabolic curved circular wire guide, the cable moves through a seal to maintain watertightness

摘要

Disclosed is an ocean or water wave-power unit for the production of electric energy. The wave-power unit comprises a floating body arranged for floating on the sea surface and an electric linear generator having a stator and a translator reciprocating along a centre axis. The stator is anchored in the bed of a sea and the translator being connected to the floating body by connection means such as a cable or wire rope or rod. The wave-power unit includes a water-tight encapsulation enclosing the generator and having an upper end wall with an opening through which the connection means extends, the opening being provided with a resilient seal that seals against the connection means, the seal being flexibly mounted so that it allows lateral and angular movements of the seal. The seal is supported by a supporting element that is mounted on said upper end wall via a flexible member, the flexible member being connected to said supporting element and to said upper end wall in a water-tight arrangement.
