Definitions

  • Prior tidal energy generation systems such as the tidal energy generation systems described in U.S. Patent Application No. 15/143,440 (which is hereby incorporated by reference in its entirety), include assemblies for capturing energy from the vertical rising and falling of the tide using a buoyant displacement vessel and converting the energy into electrical power using a directional converter mounted on the displacement vessel.
  • Other tidal energy generation systems include assemblies for capturing energy from the lateral ebb and flow of the tide using a buoyant displacement vessel having an immobile drag panel extending into the water and converting the energy into electrical power using a directional converter positioned at a stationary location, such as land.
  • FIG. 4B shows an exemplary displacement vessel having multiple vertically rotatable drag panels.
  • the tidal energy conversion assembly includes a directional converter for converting the lateral motion of the displacement vessel into electrical power.
  • the directional converter may be housed on the displacement vessel or located away from the displacement vessel, such as on land.
  • the directional converter may include a rotatable drum fixed on an axle, with at least a portion of the anchor cable wrapped around the drum.
  • the displacement vessel may be coupled by one or more anchor cables to one or more directional converters positioned at a stationary location, such as land, for example.
  • the stationary location may be a bay/ocean floor, a barge, a pier, a platform, or any other suitable location.
  • directional converter 209 includes a drum 213 around which an anchor cable may be wrapped, a drive gear 212, a gearing mechanism 214, and generators 216a-216e.
  • the directional converter 209 may further include a level winder assembly 248 configured to maintain a uniform wrapping of the anchor cable 203 as it is wound around its respective drum 213 by directing each wrap of the anchor cable 203 around the drum 213 to sit tightly next to the previous wrap.
  • the level winder assembly 248 may include a guide mechanism that guides the anchor cable as it is wound around the drum 213 so that it is wound evenly across the drum 213.
  • the guide mechanism may include a plate with a slot in which the anchor cable passes through.
  • the one or more axles may include grooves or threads arranged in a corkscrew around the axle.
  • the level winder assembly 248 may travel in the first direction along a first groove and, after travelling one full length of the drum, the level winder assembly may travel along a second groove that crosses the first groove.
  • This rotation may be achieved using control cables attached to the sides of the displacement vessel - forming a "bridle" - such that the shortening or releasing of the length of the control cable(s) allow the displacement vessel to turn, rotate, or otherwise change the angle of the drag panel relative to water flow.
  • the control cables may be attached at the ends or sides of the displacement vessel using any suitable number of connection points to connect the displacement vessel to the anchor cable.
  • the displacement vessel includes four connection points corresponding to four separate control cables and the connection points may be generally located at corners of the displacement vessel.
  • the drag panel 521 may include arms 552a and 552b extending from the drag panel 521.
  • the arms 552a and 552b may extend at any suitable angle from a surface of the drag panel and, preferably, extend from the top surface of the drag panel.
  • the arms 552a and 552b provide a lever on which the control mechanisms 520a and 520b provide force to rotate the drag panel 521 around the points of attachment to the displacement vessel 502.
  • FIGS. 6A-6C shows an exemplary displacement vessel 602 having a horizontally rotatable drag panel 621 in various positions. Similar to the displacement vessels shown in FIGS. 5A-5C, the displacement vessel 602 includes floatation devices 660a and 660b connected via transverse members 656a and 656b. A drag panel 621 is attached to the two floatation devices 660a and 660b and is also coupled to control mechanisms 620a and 620b via arms 652a and 652b that extend from the drag panel 621. In FIGS. 6A and 6C, the arms 652a and 652b extend at an angle from the drag panel 621.
  • FIG. 7 A shows an exemplary retrieval mode with the drag panel 721 retracted.

Abstract

L'invention concerne des ensembles, des systèmes et des procédés pour produire de l'énergie à partir des forces naturelles et renouvelables, plus particulièrement, pour produire de l'énergie à l'aide de l'action de la marée. Un ensemble de conversion d'énergie marémotrice comprend un navire de déplacement couplé par l'intermédiaire d'un câble d'ancrage à un convertisseur directionnel et à un générateur d'énergie électrique sur terre. Le récipient à déplacement comprend un panneau de traînée pouvant tourner horizontalement en s'étendant dans l'eau pour capturer des forces de traînée provoquées par le flux d'eau. L'écoulement d'eau contre le panneau de traînée amène le récipient à déplacement à se déplacer latéralement et à tirer sur le câble d'ancrage, exerçant ainsi une force sur le convertisseur directionnel. Le convertisseur directionnel convertit cette force en énergie de rotation qui peut être exploitée par le générateur d'énergie électrique afin de produire de l'électricité pour la consommation. Le panneau de traînée capable de tourner horizontalement peut être tourné pour ajuster la quantité d'énergie électrique produite.
