Abstract

A system for recovering wave energy and its conversion into mechanical and electrical energy, comprising a pickup member kept in a submerged position and one or more resilient lines (extensible flexible hoses) connected mechanically at one end to the pickup member and at the other end to an anchor fixed to the sea or lake bed. The interior of the resilient lines are in communication at one end with a gas-filled accumulator vessel and are blind at the other end, and are also filled with an incompressible fluid. One or more turbines and displacement engines convert the pressure and kinetic energy of the incompressible fluid into mechanical energy. The turbines are coupled to an electric generator for generating electrical energy utilizing the mechanical energy.

Dependent claims

A system for recovering wave energy and its conversion into useful energy, comprising:

(a) a pickup member kept in a submerged position;
(b) at least one resilient line connected mechanically at one end to said pickup member and at the other end to means fixed to the sea bed, the interior of said resilient line being in communication at one end with an accumulation member and being closed at the other end, and being also filled with an incompressible liquid;
(c) an accumulation member constituted by a vessel filled with gas under pressure;
(d) means for converting the pressure and kinetic energy of the incompressible liquid into mechanical energy;
(e) means for interrupting the communication between the resilient lines and the accumulation member;
and
(f) means for generating electrical energy utilizing the mechanical energy.
