Definitions

  • the present invention relates to a floating ocean wave generator that is adapted to capture the energy from the waves normally formed in the ocean to convert that energy into useful electrical energy.
  • the present invention converts the kinetic energy of waves into potential energy by using the momentum and power of the waves and thereafter converts that potential energy into the useful form of energy by directing that water having the potential energy through a water turbine where the electrical energy can be generated by the rotational movement of the water turbine.
  • a plurality of these devices can be nested offshore to provide a generator station which is cost-effective and environmentally safe.
  • the conventional approach is to use some stationary platform or structure that is in some way affixed to or based upon the land, that is, the apparatus is generally located on the land near the ocean or on some platform that is stationary and solidly affixed to the land near or underneath the ocean.
  • the purpose of the present invention is to provide an apparatus that can be entirely ocean based and which can efficiently produce electrical energy from a conversion of the energy naturally available with the movements of the ocean.
  • the present invention provides a new and improved way of capturing energy from wave activity.
  • a floating structure that is adapted to be moored to the bottom of the ocean at the selected site and is maintained at that site by Seaflex cables affixed to anchors.
  • the floatation of the present apparatus is provided by a plurality of buoyant hulls that support the structure on the surface of the ocean. In the preferred embodiment, there are three such hulls such that the overall structure is basically a trimaran type of construction.
  • a tapered ramp that receives the water propelled by a natural wave such that the water is directed upwardly along the ramp to a height that creates the potential energy.
  • the water thus exits the tapered ramp at a discharge end at that height and the water is channeled downwardly by means of gravity to make use of that potential energy by directing that downwardly flow of water through a water turbine coupled to some electrical generation system.
  • the ramp that directs and channels the water to the water turbine is preferable comprised of a plurality of individual segments or portions. That is, there is a first ramp that has one outer or inlet end positioned beneath the surface of the water and an inner end that is elevated in altitude above sea level with respect to the outer, inlet end so as to form the ramping configuration to cause the water from the surface of the ocean to be directed, by wave action, upwardly along the first ramp to a predetermined height.
  • the first ramp will have a upwardly angled configuration with the low point being below the surface of the ocean to cause the water of the wave to be forced upwardly in carrying out the present invention.
  • a second ramp is also preferably provided that has an inlet end and the second ramp is also inclined upwardly to a discharge or outlet end where the water has gained a sufficient height to achieve the necessary potential energy to operate the apparatus for the generation of electrical energy.
  • the water is channeled downwardly by gravity to a water turbine where the potential energy of the water is converted to rotational movement of the water turbine.
  • the water, propelled by the force of a wave basically moves from the surface level to a enhanced height, preferably about 10 feet of altitude above sea level, where it thus contains considerable potential energy that can thereafter be harvested by the downward channeling of that water through a water turbine to create rotational movement to be eventually transmitted to an electrical generator to produce useful electrical energy.
  • a slot is provided, preferably at or adjacent the intersection of the inner end of the first ramp and the lower end of the second ramp, where the water that does not achieve the desired height to be utilized in the water turbine is captured as it runs backwardly toward the ocean.
  • the slot collects and traps the water that has fallen short of the outlet end of the second ramp and re-channel that water collected by the slot back toward and into the water turbine so that additional energy is extracted as well as to even out the extraction of power i.e. the secondary extraction of energy is more uniform and less intermittent in nature.
  • a means to adjust the ramp angle of the first and second ramps so that the overall particular apparatus can be adjusted depending upon the size and frequency of the waves, and thus can be adjusted to optimize the harvesting of energy from the ocean at the particular location of the floating ocean electrical generating apparatus.
  • the outer or inlet end of the first ramp is movable so as to adjust the height with respect to the surface of the ocean, that is, the first ramp is preferably pivotally affixed to the overall apparatus at or adjacent its inner end so that the first ramp can be pivoted about that pivot point so as to move the outer end of the first ramp to achieve the desired angular orientation of the first ramp.
  • the actual means of raising or lowering that outer end of the first ramp can be carried out by any variety of means, including, but not limited to, hydraulic cylinders or even through the use of a line that is affixed to the outer end of the first ramp that can be pulled or let slack manually by a person and tied off with a cleat or by means of a manual or power operated winch. Accordingly, depending upon the position of the apparatus with respect to the ocean surface, the inlet end that is positioned beneath the surface of the ocean water can be adjusted so that the angle of that ramp can be selected for the particular conditions of the ocean where the apparatus is located.
  • the means of adjusting the outer end of the first ramp can be by a variety of methods or systems, and such means may be a simple as the use of a rope affixed to the outer end of the first ramp the can be pulled or released to raise or lower that end.
  • the system to adjust the angle of the first ramp can be by some automatic means such as by means of a powered winch.
  • outlet or discharge inlet end of the second ramp may also be adjustable to vary the ramp angle of the second ramp, and again, the actual means or method of adjusting the ramp angle of the second ramp can be carried out by a simple means such as a rope that raises or lowers the outlet end of the second ramp or can be automatically controlled by the use of a powered winch to adjust the ramp angle of the second ramp.
  • the apparatus can be used to extract power from the natural wave action of the ocean and can be specially adapted for use in a particular area of the ocean, that is, the first and second ramps may be adjusted so as to be appropriate to the specific site where the apparatus is to be located and the ramps pre-adjusted to fit the site, i.e. whether the normal wave action at the site is a strong powerful wave, subject to numerous storms or a more milder wave action.
  • the ramps can be adjusted for that location in advance of being anchored at the site to make sure that the apparatus is suited for that location or can be adjusted when the apparatus is actually set up at the site.
  • the apparatus can be set up and anchored to the floor of the ocean at a desired location, however, if the need for the apparatus becomes greater at an alternative location, the apparatus can simply be moved to the new location, a feature that is not as easy to facilitate with a land based unit or one that is firmly affixed to the ocean floor by a permanent structure. With the use of a floating structure, however, the overall power generation apparatus can be positioned at any desired location on the ocean offshore.
  • the overall apparatus utilizes three floatable hulls that can be made of polyethylene and held together with steel pipe and with the use of a steel plate spine for added strength.
  • the apparatus is, to the extent possible, comprised of fiberglass so as to be relatively light as well as be of a material that is not readily attacked by the corrosive salt water or other elements.
  • the ramps are comprised of light weight fiberglass beam and may be in the range of about sixty feet wide and about eighty feet in length.
  • there are fiberglass housings provided to protect the working components of the elements. While the trimaran is the preferred configuration, it is possible to use other multiple float configurations as well as to gang two or more structures together in the event additional power is required at any particular location.
  • the anchoring of the present apparatus to the floor of the ocean is carried out by the use of multiple Seaflex cables that are particularly adapted to allow the movement of the apparatus due to the buoyancy of the apparatus on the surface of the ocean while, at the same time, providing the necessary strength to insure a strong attachment to the ocean floor.
  • the actual attachment of the cables to the ocean floor is preferably carried out by means of helical anchors.

  • FIGS. 1-4 there is shown a floating ocean wave generator apparatus 20 constructed in accordance with the present invention.
  • the apparatus 20 preferably comprises a plurality of buoyant hulls 22, 24, 26, preferably three of such hulls forming a trimaran configured floating apparatus 20.

  • the overall floatation generator apparatus 20 will be considered to have a bow or front where the ocean wave enters the apparatus 20 and a stern of the apparatus 20 where the various components and equipment are located to derive the power from that wave.
  • Each one of the hulls 22-26 is constructed internally of a steel network 28 for removably mounting polyethylene floats 30 to adjust the buoyancy of the respective hull. Since all of the hulls 22, 24 and 26 are constructed in the same manner, in Fig 7 there is shown a more detailed construction of a typical buoyant hull 22 that is used with the present invention.
  • Steel plates 32 are positioned between the hulls 22-26 to support a deck 34 which can either extend across the three hulls, or which can be segmented into a first portion which extends between hulls 22,24 and a second portion which extends between hulls 24 and 26.
  • a pair of tapered, angled ramps 19, 21 which guide and channel the water from a wave that enters the apparatus 20 at the bow and from which the energy is extracted.
  • the angled ramps 19, 21 extend from below the surface of the water in order to allow the wave to pass upwardly along the surface of the angled ramps 19, 21 propelled by the energy of the wave to a high point where the kinetic energy of the natural wave action has, in effect, been converted to a potential energy to be further converted to useful energy.
  • the ramps 19 and 21 are angled such that one end is situated below the surface of the water and the highest point in the travel of that water along the ramps 19, 21 reaches an elevation of about ten feet above sea level and thus that amount of potential energy is present to be recovered as useful energy from each wave.

  • the outer end 39 is thereby adapted to be moved about the inner end 41 of the inlet ramp 35 so that the angle of the inlet ramp 35 with respect to the horizontal can be altered or adjusted as desired to match the particular conditions of the ocean. That adjustment may be made initially by the constructor of the apparatus depending upon the particular location intended for the apparatus 20 or can be adjusted at the site. If the angular adjustment is initially made, however, the feature still provides that such angle can be readjusted to the particular location for changing conditions of the wave formations or in the event that the apparatus 20 is desired to be relocated to another location.

  • the line can be moved by a manual or automatic operated winch.
  • the outlet ramp 36 again using Fig. 2 as a illustration is also adjustable as to its angle with respect to the the horizontal.
  • any number of differing systems can be used to change the angle or the outlet ramp 36, one of such means being shown via the use of a cable 43 affixed to the inner end 41 of the outlet ramp 36 and a winch 40 can be provided to alter the position of the inner end 45 of the outlet ramp 36.
  • the area of the ramps taper inwardly so that the water attains a greater height as it rushes up the respective ramps.
  • the winches 40 are mounted above the deck 34 on top of a housing 42 which extends across the deck 34 area.
  • the housing 42 is preferably of a fiberglass material so as to be resistant to the corrosive sea water and the need to be located in such hostile environment for long periods of time.
  • the inlet ramps 35, 37 as well as the outlet ramps 36, 38 are both adjustable as to the angle with respect to the horizontal level of the ocean.
  • the ramps 36,38 are adjustable depending upon the severity of wave activity and frequency thereof since the wave that forces its way up the ramps passes along the inlet and outlet ramps to provide the potential energy for utilization by the apparatus 20 to be converted to useful electrical energy.
  • the ramps 36,38 are constructed of lightweight fiberglass beams and plates and have dimensions of approximately 30' in width and 60' in length.
  • Each one of the floats 22-26 is provided with a corresponding pair of end caps 22a-b, 24a-b, and 26a-b as shown also in fig. 7.
  • the stern of the housing 42 includes a further housing cowling 44 which is, like the housing 42, preferably constructed of steel or fiberglass material.

  • a corresponding funnel assembly 54,56,58,60(54-60) precedes each one of the respective turbines 46-52.
  • the water moves upward along the inlet and outlet ramps to enter the funnel assemblies where that water, at the discharge ends 47, 49, 51 and 53 of the funnel assemblies, 54, 56, 58 and 60 attains its maximum height above sea level such that sufficient height is reached for the water to gain sufficient potential energy to produce the energy to extract the desired power from the apparatus 20.

  • the passageway 66 is specifically illustrated and it will be understood that the other passageway 64 is similarly constructed with respect to its position between buoyant hulls 22,24.
  • the passage 66 receives water that is captured by slot 55 and directs that water downwardly toward the water turbine 46 to add the potential energy of the water entering the slot 55 to further add to cause additional rotation of the water turbine 46.
  • the water entering the slot 55 and into the passageway 66 pools in a position therein shown generally at 68 where a subsequent head of water builds to continue downward onto the turbine. That additional passageway, therefore, directs the water that is otherwise returning to the ocean to be used to supplement the rotation of the water turbine 46 and thus not only adds to the energy generated or recovered from each wave, but the supplemental flow of water to the water turbine 46 additionally smooths out the generation of the rotational movement of the water turbine and, of course, the subsequent generation of electrical power.
  • the apparatus 20 is secured to the sea floor with anchor cables 70 extending to anchor assemblies (not shown) at the sea floor below.
  • the cables that are preferably utilized with the present invention are Seaflex cables that have inherent flexibility to allow the movement of the apparatus 20 resulting from the movement of the ocean but have sufficient strength to hold the apparatus 20 in the desired location.

  • the apparatus 20 is anchored such that the front or bow portion 22a,24a,26a of the floats faces incoming waves. As shown by arrow 72 in FIG. 2, the wave proceeds toward the apparatus 20 whereupon it is directed up the ramp shown generally at 74 to create a wave head at a position shown generally at 76. The size of the wave crest at 76 is determined by the elevation of the ramp 38 off the deck 34. The wave crest 76 is then guided by the funnellike structure 60 onto the turbine which is forced to rotate to provide the desired electricity.
  • not all of the wave crest 76 will proceed to the turbine. That portion of the wave crest 66 that is unable to do so, will under the effect of gravity, proceed back where it will be permitted to pool at 68 to create a secondary wave head and fall by gravity through the passageway 64 to contact a lower portion of the turbine 46 to air in the rotation of that turbine 46.
  • Figs. 5 and 6 there is shown a side view and a top plan view of the floating ocean wave generator apparatus 20 constructed in accordance with the present invention and where certain components have been omitted for clarity and to better show the pivotal movement of the inlet ramp 35 and the outlet ramp 36, those begin selected to be described with the proviso that there would normally be a plurality of such ramps positioned side by side. As shown in the present Figures, there are two of such ramps, however, there may be additional units added or ganged together to generate additional electrical power at any particular location.

Abstract

La présente invention concerne un appareil flottant générant de l'énergie électrique à partir des vagues de l'océan, qui extrait l'énergie du mouvement normal des vagues. Ledit appareil comprend une plate-forme supportée à la surface de l'océan par une pluralité de coques flottantes. Une pluralité de rampes qui s'étendent depuis sous la surface de l'océan reçoivent l'action d'une vague et canalisent cette énergie vers une extrémité de décharge surélevée par rapport au niveau de la mer. Cette énergie est récupérée, l'eau retombant sous l'effet de la gravité dans des turbines hydrauliques qui convertissent l'énergie potentielle de l'eau en mouvement rotatif. La turbine est couplée à un dispositif de génération électrique de manière que la rotation de celle-ci permet à l'appareil de fournir une énergie utilisable. Dans le mode de réalisation préféré, l'angle de chaque rampe peut être réglé individuellement afin de tenir compte de la fréquence et de la force des vagues en un emplacement particulier où l'appareil a été installé.
