Definitions

  • the invention relates to the field of conversion of kinetic and potential energy caused by winds on oceans and seas, to electrical energy.
  • Shoreline Applications In shoreline applications, energy production structures are fixed at or buried on the shore. Maintenance and construction is easier when compared to other counterparts and there is no need for deep water connections or long underwater electric cables. However, because of the less powerful wave regime, wave energy is produced less. This application is limited by factors such as coastline geology, tide levels and protection of shore shape.
  • Oscillating Water Column These systems work with the principle of water level in open-ended underwater chambers rising and falling with the motion of waves. When waves rise, water level inside the chambers rise, rising water column pushes the air column towards a vent. The air squeezed by water turns the turbine placed within the narrow vent. When the wave draws back, it empties the air column, with the motion of which the turbine turns again. In this system, Wells turbines are used that ensure unidirectional motion.

  • These systems comprise tapered channels that feed a reservoir built near cliffs, with wall heights between 3 to 5 meters. As the water travels from the wide end to the narrow end, water level rises and risen water fills the reservoir. Water is stored in the reservoir, meaning the kinetic energy of the wave being converted to potential energy. Stored water is then sent to the turbines. High reliability and low maintenance is a feature of this application, since it has very few moving parts. Energy can be stored in this system until necessary. It is used in topographically suitable ocean shores and with high waves. Since kinetic energy is not used, efficiency is around 2 to 3%.
  • Pendular In the shape of a rectangular box with one side opening to the sea, in this system, wave motion causes piston arms and lids beneath the platform to move, with the motion of which liquid is directed with high pressure to the hydraulic pump, turning the turbine connected to the generator.
  • Osprey Developed by Wavegen, power of Osprey is 2 MW with the addition of a 1,5 MW wind turbine. Commercial presentation of this product is rigorously worked on, and still it is imperative that construction costs are reduced.
  • Oyster This system comprises two units. An oscillator fixed on the sea bottom that oscillates with the wave motion conveys this motion to pistons/hydraulic arms and delivers the seawater to the unit on land. Hence Pelton turbine alternators on the land unit work. First became operational in 2012, oscillator width was 18 meters. Active today, water is pumped to land from the 26-meter wide oscillator 500 meters offshore, the maximum capacity of which is 800 kWh. Carnegie Project (CETO): Joint venture by Australia and France. Buoys that are 5 meters high and 7 meters wide are placed 1 to 2 meters below sea level. This buoy is connected to the piston of the water pump via steel connectivity elements. Underwater pump converts kinetic energy to hydraulic energy.
  • Hydraulic pump is fixed on a foundation 20 to 50 meters below sea level. Pumping motion takes place, unaffected by whichever direction the waves travel. Hydroelectrical turbine and generator that the hydroelectric pump feeds with highly pressurized water produces electricity. Generator and electricity installment being on land is advantageous regarding maintenance and repair.
  • Azura This 40-tonne pale yellow device located in Hawaii's Kaneohe Island US Marine Corps Base Wave Energy Test Site (WETS), is to be the first of the wave generator fleet aimed at providing clean, renewable energy to coastal US cities, according to the Department of Energy. Prototype only produces 20 kWh, which can be considered small; however clean energy provided by similar structures can satisfy the needs of coastal cities, it is asserted.
  • the project which is supported by USMC is operated jointly with Northwest Energy Innovations.
  • the prototype installed reaches around 30 meters in depth, and can convert both upsurge (vertical) and undulation (horizontal) motions up to 40 tons to electrical energy.
  • Wosp 3500 Wosp 3500: WOSP (Wave Ocean Energy Release) is the combination of near-shore wave and wind energy plants. With the added wind capacity of 1.5 MW, the overall capacity is increased to 3.5 MW.
  • WOSP Wide Ocean Energy Release
  • Offshore Applications These are devices that are installed in waters deeper than 40 meters. Some of the known applications include:
  • McCabe Wave Pump This device comprises 3 rectangular steel floats, each 4 meters in width, hinged together neatly and move jointly. Inertia of the central float is increased with an additional mass. Energy is harnessed with hydraulic pumps on the hinges at both sides of the central float, using the motion at the hinges.
  • a 40-meter long exemplary device is installed offshore Kilbaha in Country Clare, Ireland.
  • OPT Wave Energy Converter Comprises a cylindrical structure 2 to 5 meters in diameter, open at its end facing the sea floor and closed on the other end. Between the top end and the steel floater situated inside is a hydraulic pump. Electricity is produced from the movement of the structure related to the floater. This system has been tested extensively in Eastern Atlantic Ocean and first commercial products are about to be installed in Australia and Pacific Ocean.
  • Pelamis This structure comprises partially submerged cylindrical chambers hinged together in a joint fashion. Waves produce movement at the joint locations, motion caused by which runs the electrical generators through hydraulic pumps. In 2009, the system which is 130 meters in length, 3.5 meters in diameter and with a capacity of 375 kW has begun supporting the grid.
  • Hydroelectric power plants albeit being renewable energy resources, end up altering humidity and seasonal temperature levels in the surrounding area due to excess evaporation in the dam reservoir, causing animal species to suffer adaptation difficulties and their habitats to get smaller.
  • Energy produced from botanical oils like soy oil are criticized for the same reason, since they utilize agricultural areas and freshwater sources for irrigation which are already scarce. Wind farms are also targeted to criticism for causing noise and visual pollution.
  • Mean daily solar energy flow is 100 W per square meter. Thus; ideally 10 meter squares of solar cell area is needed for an output of 1 kW. For wind energy, 2 meter squares are sufficient for the same amount. For wave energy, this is only one square meter.
  • Consistent/Continuous energy On most places around the globe, wind movement is strong and consistent enough to form continuous waves. Moreover, depending on the fetch of the wind, waves can travel thousands of kilometers without a change in shape or energy, even well after the wind that formed them has died down. For example, waves formed at the American side of the Atlantic can reach European shores. Seasonal change has a very limited effect on wave nature.
  • Environmentally friendly These systems are completely environmentally friendly, produces no physical, chemical or organic pollutants/waste. Since it will replace the share of the fossil fuels in energy production, it will reduce greenhouse emissions, therefore global warming and acid precipitation, increasing the quality of breathable air. Its limited land presence protects agricultural areas and prevents the chopping down of forests.
  • Wave energy systems constitute an artificial habitat for aquatic organisms, helping fish reproduce.
  • an ideal wave energy converter should have the following properties:
  • the invention having the listed properties aside, is favorable in means of initial investment and maintenance costs; a feature of its simple structure. In addition, it can generate power at wavelengths at which other systems are not active or perform inefficiently. This enables it to operate in higher efficiency, and also increasing the electricity producing area, increasing the available potential.

  • buoys (1, 2) that are in integral form or lie on a skeleton as a group. Underneath these buoys (1, 2) which have wide surfaces, are several Venturi tubes (4), top and bottom ends of which are open.
  • the distance between two crests (or two troughs) are 25 to 40 meters in shallow waters, and 40 to 200 meters in open sea and ocean waters. Therefore, it is not inconvenient, in a conversion system, for the buoys (1, 2) to have large surface areas, as long as it falls within these ranges.
  • buoy (1, 2) surface area can be increased even more in great wave amplitudes
  • design for these instances may include one group of tubes (4) away from the center with distance X, and another group of tubes (4) with distance Y.
  • the buoy (1) depicted in Fig. 1 comprises 9 (nine) tubes (4).
  • Buoy group (2) In Fig. 2 on the other hand, characterized by two rows of connectivity points away from the center with a certain distance and attached to a skeleton, is designed for open sea applications where wave amplitude is high, in order to reduce wave decay of the system and to efficiently use designated area. Accordingly, whichever way the front of the wave approaches the buoy (1, 2), even if the tubes (4) oscillating between the crest and trough of a wave are arranged differently, all of them will go up and down respectively, generating electricity. Second benefit is increased efficiency.
  • the tubes (4) that are closest to it will also have risen past the level of the crest.
  • the center of the buoy (1, 2) reaches the crest, all the tubes (4) including the ones that are at the same level with the front of the wave will be rising along with the buoy (1, 2); and when the tube (4) which contacted the wave first starts to fall down towards the trough, tubes (4) on the opposite sides begin to rise.
  • buoy (1, 2) in the invention much more efficient compared to the applications which are characterized by groups of buoys (1, 2) with smaller surface areas covering the same area, or ones of identical size but has one tube (4).
  • each of the multiple tubes (4) situated on the bottom of the buoy (1, 2) rise to heights greater than the wave crest, therefore significantly increasing the amount of water traveling through the turbines (10, 11) on the openings (9, 12) of the tubes (4).
  • the system also broadens the application areas and increases the wave energy potential greatly. Depending on the wave characteristics on the site, adjustments on the buoy (1, 2) length and tube (4) diameter see to the design flexibility for maximum efficiency.
  • the first tube (4) that passes the crest can rise almost twice as much as the wave height, whereas the tubes (4) immediately after it can rise 1.5 times as much.
  • the invention also includes design details to protect the converter system against mechanical or electrical overload. First, it is to be elaborated on the mechanical load.
  • Waves are not merely a body of water flowing in one direction: As the wind blows, acting on the molecules on the surface, molecules circularly move towards the bottom before returning to their initial position. This motion is conveyed to other molecules and they too move in this fashion. Surface molecules move in a circle almost standard in diameter. Subsurface molecules that are not affected by the kinetic energy load of the wind are only acted upon by surface molecules. In short, greater fetch and longer time increase the diameter of the motion, as well as its effective depth. As water gets deeper, the diameter of the circular motion gets smaller, and dies down completely if the body of water is sufficiently deep.
  • the part of a conversion system exposed to the greatest amount of load is located on the surface.
  • the only part of the system in this invention that is above the surface is an integral buoy (1) or a group of buoys fixed together by means of a skeleton (2).
  • buoys (1, 2) Since the only purpose of these buoys (1, 2) is to provide maximum buoyancy, no other elements exist, save the beams that distribute/carry the weight resulting from the subsurface elements in oscillation. Thus, having quite great interior volume makes the buoyant force accordingly great.
  • Said buoyant force is, with the aid of the connectivity elements on its bottom, conveyed to the arm characterized in Fig. 12, 13 and 14, which itself has two connectivity elements at both ends. Every connection the system in the invention has is facilitated by use of ball-bearing hinges, rings or universal joints. And as they are represented naked to make them visible; joints are protected against sea water with a sheath, like that of axle connections in automobiles.
  • the sole purpose of the arms (6) is to convert the horizontal oscillation of the buoy (1, 2) into vertical motion on the tubes (4) and since they extend to depths at which the circular wave motion dies down, they protect the tubes (4) from the effects thereof.
  • This filter (8) covering the cages (5) exist so as to prevent waste material like nylon bags and sea animals of certain size from entering the tubes (4) and damaging turbines (10, 11), protecting the system and marine life. Material and animals small enough to pass through the filter (8) pose no damage as is to the system.
  • Cage (5) and filter (8) do not resist water passing through the tubes (4) in any significant way.
  • the noteworthy resistance occurs as water coming in from the openings of the tubes (4) travels towards the narrowing channels (9, 12), in which turbines (10, 11) are located.
  • the large buoyancy the buoys (1, 2) easily overcome this resistance that occurs when tubes (4) rise.
  • the velocity of the tubes (4) changes with respect to their position on the buoy (1, 2), the direction and height of the wave.
  • the tubes (4) that rise the most are the ones located at the end of the buoys (1, 2) that first meet, and move past the crest of the wave.
  • the tubes closer to the center rise less, and the innermost tube can only rise as much as the crest height. So, the center of the buoys (1, 2) that move mostly vertically, only rises as high as other buoyed (1, 2) systems.
  • buoy (1, 2) slowly climbs the crest (in half the wave period) and falls to the trough.
  • the wave height increases, amplitude decreases, which means steeper waves; and when the center of the buoy (1, 2) is on the crest, the free end of the buoy (1, 2) will tend to fall at once because of its weight.
  • the tube on the other side of the crest (4) will want to rise just as fast.
  • the first solution the present invention has for this problem is the existence of multiple channels (9, 12) in each tube (4), and putting independent turbines (10, 11) in each channel (9, 12). Moreover, at least one channel (9, 12) has lids (14, 28) on both top and bottom openings, and lid holders (15, 29) that hold or release lids (14, 28) in case of need.
  • channels (9, 12) can be in rectangular or round form.
  • a Wells turbine (10) Inside channels (9, 12) in round form is a Wells turbine (10), and inside channels in rectangular form (12) is a Banki turbine (11) cross-flow, characterized by an alternator (13) in Fig. 4.
  • Wells turbines (10) are already designed specifically for usage in systems in which gas or liquid flow changes direction, and they rotate unidirectionally at all times. Such turbines (10) are directly connected to the alternator (13) shaft without any need for transmission elements such as gears or pulleys. And as they are generally situated inside a narrowing tube (4) channel (9), as is the case with the present invention; even if the direction the liquid entering the tube (4) changes, for it to come to the turbine (10) along the same motion lines, a single shaft with rotors on both ends between which the turbine (10) is inserted exists.
  • Banki turbines (11) have reciprocal circles at center, in addition to numerous narrow wings that start at a certain distance from the center and move towards the outer edge of the circles with a predefined angle. And to increase the power of the water hitting the winds of the turbine (11), water is delivered through a narrowing path, return of which is in one direction.
  • narrowing blockers (3) are attached in the middle of the channel (12) ensuring fluid pathways in both directions, both of which are closed with lids (28). So, as the tube (4) moves up and down, lids (28) open with respect to the wings of the turbine (11), and the alternator (13) connected to the turbine (11) moves unidirectionally.
  • desired number of turbines (10, 11) can be activated or deactivated. Whether if a stopper (15, 29) is going to release a lid (14, 28) can be adjusted via the flow of water in the channel (9, 12) or circuitry (16) that measures the rise and fall rate of the tubes (4).
  • buoy (1, 2) design may also be considered to alter the buoy (1, 2) design to situate all tubes (4) under the buoy (1, 2) in parallel with the wave front.
  • Fig. 12 comprising independent buoys (1, 2) or as represented in Fig. 11, the weight at the seafloor (25) having been associated with a pendulum (17) using a floor arm (26) and rope (27), are specifically envisioned to facilitate such methods.
  • the arm (26) is designed in two pieces, one of which moves inside the other, so as not to obstruct the buoy's(l, 2) rise and fall and lessen the buoyancy.
  • the rope (27) is meant to costlessly cover the distance from the pendulum (17) to the seafloor weight (25), and to limit the length of the arm (26) to the maximum wave height at that site, connecting the arm (26) and the pendulum (17). Because of this, the connection point at the bottom of the pendulum (17) is rotatable.
  • the present invention in addition to reducing the risk of the vertical axis of the tube (4) being disoriented when pulled fast down with high and steep waves, and the risk of collision between themselves (4); also includes an element that increases the buoy (1, 2) angle a certain amount and supports the fall velocity of the tube (4).

  • Length of the arms (20) are as much as the distance between the rings under the cages (5) and the pendulum (16, 17) when the buoy (1, 2) is stationary; and is slightly tilted towards the tubes (4) with a small angle. Weights (22) inside the arm (20) are stacked in the direction of the tube (4). And when one side of the buoy (1, 2) wants to rise, it lifts the weights (22) of the respective arm (20).
  • the wheel apparatus (23) will move within the rail (21), shifting the tilt of the arm (20) towards the pendulum (17) quickly, stacking the weights (22) towards the pendulum (17). So, the rail (21) makes sure that the arm (20) does not block the displacement between the tube (4) and the pendulum (17), resulting from the buoy's (1, 2) movement with the waves.
  • weights (22) in the arm (20) related to the tubes (4) on the end of the buoy (1, 2) that climbs the crest moving to the center and the ones on the reciprocal end moving towards beneath the tube (4); will shift the center of mass from the buoy center towards the trough. This partly supplies the gain in elevation and the angle change when the buoy (1, 2) oscillates.

  • Main function of the pendulum (17) represented in connection with the tube (4) cage (5) under the center of the buoy (1, 2), as represented in all respective figures, is to connect different parts of the converter or converter groups.

Abstract

Cette invention comprend des bouées (1, 2) avec des surfaces très larges situées sur un squelette en groupes. Sur la surface inférieure des bouées (1, 2) se trouvent plusieurs tubes de Venturi (4) dont les deux extrémités sont ouvertes. Lorsque la bouée (1, 2) monte au sommet de la vague et glisse vers le creux, elle déplace les tubes (4) vers le haut et vers le bas ; l'eau entrant dans les tubes acquière de la vitesse du fait de la réduction de la colonne, fait tourner les turbines (10, 11) à l'intérieur de la colonne (9, 12) et les turbines (10, 11) font tourner l'alternateur (13), produisant de l'énergie électrique. Les alternateurs (13) sont directement excités par l'eau de mer déplacée par le mouvement des tubes (4) sans aucun élément de distribution de puissance qui agit en friction ou exposé à la puissance des vagues.
