DEVICE WHICH CONVERTS TIDAL KINETIC ENERGY INTO ELECTRIC ENERGY AND COMPRISES A CROSS-FLOW WATER TURBINE CAPABLE OF DIRECTING THE CAPTURED FLOWS IN AN OPTIMAL MANNER, REDIRECTING AND ACCELERATING SAME TOWARD AN INNER RUNNER OF THE WATER TURBINE, AND AN ELECTRICITY GENERATING PLANT THAT USES SAID DEVICE

摘要

The invention relates to a cross-flow water turbine and a plant for generating electricity from the movement of the tides and waves of the sea that operates using said device, which is capable of capturing and directing the flows in an optimised manner, which operates with a runner connected to a conventional electricity generator, wherein the runner is of the type having curved-profile longitudinal blades arranged at an angle to the longitudinal central axis of the runner, said device including a surrounding, structuring case which has a cylindrical central body in which the runner is accommodated and two diametrically opposite directing ducts having flow intake/outlet openings; also including means for directing and accelerating flows made up of three types of directing plates, inner directing plates which are adjacent to the blades of the runner, outer directing plates which extend inside and across the entire length and depth of the ducts and intermediate directing plates which extend from the middle area of the ducts until the inner directing plates; also including means for guiding the inner flows of the runner, which include three guiding plates and a series of vortex inhibitors which are arranged inside and along the runner.
