Description
Foreliggende oppfinnelse angår en innretning for utvinning av energi fra vannbevegelser, fortrinnsvis hav eller sjøbølger, samt omforming av den uttatte energi til nytteenergi. Innretningen som flyter i vannet innbefatter to hovedkomponenter som kan bevege seg i forhold til hverandre når bølger virker på innretningen. De relative bevegelser som oppstår mellom hovedkomponentene overføres til energiomformere som genererer nyttig energi. The present invention relates to a device for extracting energy from water movements, preferably ocean or sea waves, as well as transforming the extracted energy into useful energy. The device that floats in the water includes two main components that can move in relation to each other when waves act on the device. The relative movements that occur between the main components are transferred to energy converters that generate useful energy.
Det er tidligere kjent innretninger som skal omforme bølgeenergi til nytteenergi. Det vises til følgende publikasjoner: GB 2261262 som viser et ringformet flytelegeme dreibart opplagret på toppen av en vertikal søyle. Bølgebevegelser vil forårsake at flytelegemet dreier om horisontal akser. Flytelegemets dreiebevegelse i forhold til søylen blir via et transmisjon system overført til en generator som er montert i søylen. Innretningen utnytter kun relativ dreiebevegelse mellom flytelegemet og søylen. Transmisjons systemet består av relativt mange deler. Forankringen av innretningen er relativ komplisert. There are previously known devices which will transform wave energy into useful energy. Reference is made to the following publications: GB 2261262 which shows an annular floating body rotatably supported on top of a vertical column. Wave movements will cause the floating body to rotate about a horizontal axis. The floating body's rotational movement in relation to the column is transferred via a transmission system to a generator that is mounted in the column. The device only utilizes relative rotational movement between the floating body and the column. The transmission system consists of relatively many parts. Anchoring the device is relatively complicated.
US 5986349 viser et ringformet flytelegeme montert omkring en vertikal søyle. Det ringformet flytelegemet er delt i fire segmenter som er hengslet til søylen. Segmentene kan bevege seg uavhengig til hverandre. Bølgebevegelser vil forårsake at segmentene beveger seg opp og ned. Den relative bevegelse mellom flytelegeme-segmentene og søylen utnyttes til å drive energiomformere. Forankringen av innretningen er relativ komplisert. US 5986349 shows an annular floating body mounted around a vertical column. The annular floating body is divided into four segments which are hinged to the column. The segments can move independently of each other. Wave motion will cause the segments to move up and down. The relative movement between the floating body segments and the column is used to drive energy converters. Anchoring the device is relatively complicated.
US 4352023 viser en gyroskop mekanisme montert på et flytelegeme. Under påvirkning av bølger vil flytelegemet dreie eller pendle om horisontal akser. Gyroskop mekanismen omformer dreiebevegelsen av flytelegemet til rotasjon for drift av generatorer. Innretningen utnytter ikke relative bevegelser mellom to legemer som befinner seg i vann. US 4352023 shows a gyroscope mechanism mounted on a floating body. Under the influence of waves, the floating body will rotate or oscillate about a horizontal axis. The gyroscope mechanism transforms the turning movement of the floating body into rotation for the operation of generators. The device does not utilize relative movements between two bodies that are in water.
"The Kepler Buoy" publisert på Internett. Innretningen består av et sirkelformet flytelegeme glidbart montert øverst på en vertikal søyle samt en sirkelformet plate fast montert nederst på søylen. Under påvirkning av bølger vil flytelegemet bevege seg opp og ned mens søylen blir holdt igjen på grunn av platen møter motstand i vannet. Den relative bevegelsen mellom flytelegemet og søylen utnyttes for å generere nyttig energi. Innretningen utnytter kun relativ opp/nedgående bevegelser mellom legemene. "The Kepler Buoy" published on the Internet. The device consists of a circular floating body slidably mounted at the top of a vertical column and a circular plate fixedly mounted at the bottom of the column. Under the influence of waves, the floating body will move up and down while the column is held back due to the plate encountering resistance in the water. The relative motion between the floating body and the column is utilized to generate useful energy. The device only utilizes relative up/down movements between the bodies.
Foreliggende oppfinnelse innbefatter et flytelegeme (1) anbrakt omkring et vertikalt langstrakt legeme (2), kobling (4, 5, 6, 7, 8) og energiomformere (9,10, 11) som drives av flytelegemets (1) relative bevegelser i forhold det vertikalt langstrakt legeme (2). Det vertikalt langstrakte legemets (2) nedre del befinner seg under vann og øvre del går opp gjennom flytelegemet (1) og er koblet til flytelegemet (1) med koblingen (4, 5, 6, 7, 8). The present invention includes a floating body (1) placed around a vertically elongated body (2), coupling (4, 5, 6, 7, 8) and energy converters (9, 10, 11) which are driven by the relative movements of the floating body (1) in the vertically elongated body (2). The lower part of the vertically elongated body (2) is underwater and the upper part goes up through the floating body (1) and is connected to the floating body (1) with the coupling (4, 5, 6, 7, 8).
Innretningen kan utstyres med forskjellige typer energiomformere for å generere ulike former for nytteenergi som elektrisk energi, trykkenergi etc. The device can be equipped with different types of energy converters to generate different forms of useful energy such as electrical energy, pressure energy etc.
Det spesielle med foreliggende oppfinnelse i forhold til kjent teknikk er at flytelegemet (1) er innrettet for både aksial bevegelse og dreiebevegelse i forhold til det vertikalt langstrakte legemet (2) slik at energien i begge disse bevegelsene utnyttes. The special feature of the present invention compared to prior art is that the floating body (1) is arranged for both axial movement and rotational movement in relation to the vertically elongated body (2) so that the energy in both these movements is utilized.
I tillegg utnytter foreliggende oppfinnelse horisontale frem og tilbake bevegelser. Horisontale frem og tilbake bevegelser av innretningen vil oppstå når den er fortøyd til en bøye eller en annen anordning som virker fjærende. Horisontale frem og tilbake bevegelser vil forårsake pendelbevegelser av det vertikalt langstrakte legemet (2) slik at det oppstår relative dreie bevegelser mellom flytelegemet (1) og det vertikalt langstrakte legemet (2). In addition, the present invention utilizes horizontal back and forth movements. Horizontal back and forth movements of the device will occur when it is moored to a buoy or other device that acts as a spring. Horizontal back and forth movements will cause pendulum movements of the vertically elongated body (2) so that relative turning movements occur between the floating body (1) and the vertically elongated body (2).
Foreliggende oppfinnelse er arrangert slik at kreftene i de relative bevegelsene mellom flytelegeme (1) og det langstrakte legemet (2) skal bli størst mulig. The present invention is arranged so that the forces in the relative movements between the floating body (1) and the elongated body (2) should be as large as possible.
Dette oppnås for det første ved utformingen av flytelegemet (1) som har et stort volum i forhold til egenvekten slik at oppdriftskreftene blir størst mulig. For at dreiebevegelsene skal bli størst mulig er flytelegemets (1) tverrsnitt, anvist på snitt B-B i figur 7, formet slik at nederste del (lc) er forholdsvis smal eller spiss for å minske motstanden i vannet når det dreier. This is achieved, firstly, by the design of the floating body (1), which has a large volume in relation to its own weight, so that the buoyancy forces are as large as possible. In order for the turning movements to be as large as possible, the cross-section of the floating body (1), indicated on section B-B in figure 7, is shaped so that the bottom part (lc) is relatively narrow or pointed to reduce the resistance in the water when it turns.
Det vertikalt langstrakte legemet (2) er innrettet for å virke som et mothold i forhold til flytelegemet (1) slik at kreftene i de relative bevegelsene blir størst mulig. Dette oppnås ved at det vertikalt langstrakte legemet (2) utstyrt med et kammer (3) som helt eller delvis omslutter en vannmasse. Dersom det vertikalt langstrakte legemet (2) skal akselerere og bevege seg må vannmassen i kammeret (3) samt nærliggende vannmasse utenfor følge med. For å akselerere denne vannmassen (hydrodynamisk masse) kreves det en kraft (treghetskraft). I tillegg kreves det en kraft for å overvinne motstanden (hydrodynamisk dempning) det vertikalt langstrakte legemet (2) og kammeret (3) møter når de beveger seg i vannet. Treghetskraften og den hydrodynamiske dempningen vil således motvirke at det vertikalt langstrakte legemet (2) beveger seg. I tillegg er det vertikalt langstrakte legemet (2) innrettet for at bølgekreftene på det skal bli minst mulig. Dette oppnås ved at det har et forholdsvis lite volum og er smalt nær vannoverflaten hvor bølgepartikkel hastigheten er størst. Kammeret (3) vil i liten grad påvirkes av bølgekrefter ettersom det er plassert et stykke nedenfor vannoverflaten hvor bølgepartikkel hastigheten er forholdsvis lav. The vertically elongated body (2) is designed to act as a counterweight in relation to the floating body (1) so that the forces in the relative movements are as large as possible. This is achieved by the vertically elongated body (2) equipped with a chamber (3) which completely or partially encloses a body of water. If the vertically elongated body (2) is to accelerate and move, the mass of water in the chamber (3) as well as the nearby mass of water outside must follow. To accelerate this mass of water (hydrodynamic mass) a force (force of inertia) is required. In addition, a force is required to overcome the resistance (hydrodynamic damping) encountered by the vertically elongated body (2) and chamber (3) as they move through the water. The inertial force and the hydrodynamic damping will thus prevent the vertically elongated body (2) from moving. In addition, the vertically elongated body (2) is arranged so that the wave forces on it are as small as possible. This is achieved by the fact that it has a relatively small volume and is narrow near the water surface where the wave particle speed is greatest. The chamber (3) will be little affected by wave forces as it is located a short distance below the water surface where the wave particle speed is relatively low.
Et av formålene med foreliggende oppfinnelse er å frembringe en innretning som består av fa deler og er enkel og billig å fremstille. One of the purposes of the present invention is to produce a device which consists of several parts and is simple and cheap to manufacture.
Et annet formål med oppfinnelsen er å frembringe en innretning som er enkel å anvende. Utstyret for omforming av energi er plassert slik at det er lett tilgjengelig for inspeksjon og reparasjon. Innretningen kan fortøyes på en enkel måte ved bruk av en eller flere liner som festes til bøyer eller til land. Another purpose of the invention is to produce a device which is easy to use. The energy conversion equipment is located so that it is easily accessible for inspection and repair. The device can be moored in a simple way using one or more lines that are attached to buoys or to land.
Ovennevnte fordeler oppnås ved å utforme foreliggende oppfinnelse i henhold til de fremsatte patentkrav. The above advantages are achieved by designing the present invention in accordance with the patent claims.

Tegningene er primært ment som prinsipptegninger for forklaring av prinsippene for foreliggende oppfinnelse. Alle nødvendige konstruksjonsdetaljer er således ikke vist. Videre er størrelsene til legemenene og komponentene i forhold til hverandre nødvendigvis ikke i skala. Det nevnes også at de samme referansetall er benyttet for tilsvarende elementer og komponenter på alle figurene. Det gjøres oppmerksom på at figurene bare viser et utførelseseksempel som kan varieres på mange måter, for eks. kan elementene ha forskjellige tverrsnittsformer og ytre former. The drawings are primarily intended as principle drawings for explaining the principles of the present invention. All necessary construction details are thus not shown. Furthermore, the sizes of the bodies and components in relation to each other are necessarily not to scale. It is also mentioned that the same reference numbers are used for corresponding elements and components in all the figures. Please note that the figures only show a design example which can be varied in many ways, for example the elements can have different cross-sectional shapes and external shapes.
Elementene og komponentene kan lages i mange forskjellige typer materialer som for eks. komposittmaterialer, plast, metaller etc. The elements and components can be made in many different types of materials such as e.g. composite materials, plastics, metals etc.
Fig. 1 viser foreliggende oppfinnelse som innbefatter flytelegeme (1), vertikalt langstrakt legeme (2) med kammer (3) nederst, kobling (4, 5, 6, 7, 8) og energiomformere (9, 10, 11). Koblingen innbefatter en lageranordning for aksial bevegelse (4), lageranordninger for dreiebevegelse (5), ramme (6) og lageranordninger for dreiebevegelse (7, 8), Fig. 1 shows the present invention which includes floating body (1), vertically elongated body (2) with chamber (3) at the bottom, coupling (4, 5, 6, 7, 8) and energy converters (9, 10, 11). The coupling includes a bearing device for axial movement (4), bearing devices for rotary movement (5), frame (6) and bearing devices for rotary movement (7, 8),
Flytelegemet (1) kan for eks. være en skallkonstruksjon avstivet med plater eller et massivt legeme bestående av et lettvekts materiale. Videre kan flytelegemet (1) være sirkelformet som vist på tegningene eller kantet. The floating body (1) can, for example, be a shell structure stiffened with plates or a massive body consisting of a lightweight material. Furthermore, the floating body (1) can be circular as shown in the drawings or angular.
Den øvre del av det langstrakte legemet (2) er innrettet for at lageranordningen The upper part of the elongated body (2) is arranged so that the bearing device
(4) skal kunne bevege seg dets aksiale retning. (4) shall be able to move in its axial direction.
Midterste og nederste del av det vertikalt langstrakte legemet (2) kan for eks. være en sylinder eller rør med rundt eller flere kantet tverrsnittsform. The middle and bottom part of the vertically elongated body (2) can, for example, be a cylinder or tube with a round or more angular cross-section shape.
Det vertikalt langstrakte legemet (2) er fortrinnsvis utstyrt med et kammer (2b) for å frembringe oppdrift. The vertically elongated body (2) is preferably equipped with a chamber (2b) to produce buoyancy.
Størrelsen på oppdriftskraften kan varieres slik at det vertikalt langstrakte legemet (2) flyter uavhengig av det flytelegemet (1) eller at det vertikalt langstrakte legemet (2) utøver en oppover rettet kraft på det flytelegemet (1). The magnitude of the buoyancy force can be varied so that the vertically elongated body (2) floats independently of the floating body (1) or that the vertically elongated body (2) exerts an upwardly directed force on the floating body (1).
Et annet alternativ er at vekten av det langstrakte legemet (2) bæres helt eller delvis av flytelegemet (1). Another alternative is for the weight of the elongate body (2) to be carried in whole or in part by the floating body (1).
Avstanden fra mekanismens (5, 6 ,7, 8) dreie akse og flytelegemets (1) egen dreieakse i vann har betydning for dreiebevegelsene. For å optimalisere dreiebevegelsene kan denne avstanden avvike fra det som er vist på tegningen. The distance from the turning axis of the mechanism (5, 6, 7, 8) and the floating body's (1) own turning axis in water is important for the turning movements. In order to optimize the turning movements, this distance may deviate from what is shown in the drawing.
Flytelegemets (1) bevegelse i det vertikalt langstrakt flytelegeme (2) aksiale retning dvs. opp/ned bevegelser er muliggjort ved hjelp av lageranordningen (4). The movement of the floating body (1) in the vertically elongated floating body (2) axial direction, i.e. up/down movements, is made possible by means of the bearing device (4).
Flytelegemets (1) dreiebevegelser i forhold til det vertikalt langstrakte legeme (2) , dvs. dreining om akser i horisontalplanet, er muliggjort ved at lageranordningen (4) er dreibart opplagret i rammen (6) ved hjelp av lageranordninger (5) og at rammen (6) er dreibart opplagret på flytelegemet (1) ved hjelp av lageranordninger (7, 8). The pivoting movements of the floating body (1) in relation to the vertically elongated body (2), i.e. rotation about axes in the horizontal plane, are made possible by the fact that the bearing device (4) is rotatably supported in the frame (6) by means of bearing devices (5) and that the frame (6) is rotatably supported on the floating body (1) by means of bearing devices (7, 8).
Innretningen er utstyrt med energiomformere (11) som utnytter lageranordningens (4) aksial bevegelse langs det vertikalt langstrakte legemet (2). Nedre del av energiomformerene (11) er mekanisk forbundet til lageranordningen (4) og øvre del er mekanisk forbundet til det langstrakte legemets (2) øvre del. The device is equipped with energy converters (11) which utilize the axial movement of the bearing device (4) along the vertically elongated body (2). The lower part of the energy converters (11) is mechanically connected to the bearing device (4) and the upper part is mechanically connected to the upper part of the elongated body (2).
Innrettingen er i tillegg utstyrt med energiomformere (9, 10) som utnytter flytelegemets (1) dreiebevegelser i forhold til det vertikalt langstrakte legemet (2). Energiomformeren (10) er forbundet til rammen (6) og har mekanisk forbindelse til lageranordningen (4). Energiomformeren (9) er forbundet til flytelegemet (1) og har mekanisk forbindelse til rammen (6). The arrangement is also equipped with energy converters (9, 10) which utilize the turning movements of the floating body (1) in relation to the vertically elongated body (2). The energy converter (10) is connected to the frame (6) and has a mechanical connection to the bearing device (4). The energy converter (9) is connected to the floating body (1) and has a mechanical connection to the frame (6).
Plasseringene av energiomformerene (9,10, 11) kan varieres for å oppnå en best mulig plassering med hensyn på overføring av bevegelsene. I tillegg kan antall energiomformere varieres. The locations of the energy converters (9,10, 11) can be varied to achieve the best possible location with regard to the transmission of the movements. In addition, the number of energy converters can be varied.
De relative bevegelser mellom flytelegemets (1) og det langstrakte legemet (2) blir således utnyttet til å utføre arbeid på energiomformerene (9, 10, 11) som generer nyttig energi, for eksempel elektrisitet. På grunn av at energien fra bølgene vil være ujevn kan det være hensiktsmessig å lede elektrisiteten til et batteri eller annet apparat for midlertidig lagring slik at den uttatte energien blir jevn. Batteriet eller apparatet kan for eks. være plassert øverst i det vertikale langstrakte legemet (2). The relative movements between the floating body (1) and the elongated body (2) are thus utilized to perform work on the energy converters (9, 10, 11) which generate useful energy, for example electricity. Due to the fact that the energy from the waves will be uneven, it may be appropriate to direct the electricity to a battery or other device for temporary storage so that the extracted energy is uniform. The battery or device can, for example, be located at the top of the vertical elongated body (2).
Det nevnes også at innretningen kan utstyres med forskjellige kontroll systemer for å styre og optimalisere energi produksjonen. It is also mentioned that the facility can be equipped with different control systems to manage and optimize energy production.
For å ytterlig øke energi produksjonen kan innretningen utstyres med en vindmølle for også å utnytte vindkrefter. Vindmøllen kan for eks. plasseres på toppen av det vertikalt langstrakte legemet (2). To further increase energy production, the facility can be equipped with a windmill to also utilize wind power. The windmill can, for example, is placed on top of the vertically elongated body (2).
Fig. 5 og 6 viser eksempel på fortøyning av innretningen der referansetall (12,13) referer til festepunkter for fortøyningsliner og referansetall (14, 15) referer til fortøyningsliner. Innretningen kan med fordel være fortøyd til bøyer eller andre anordninger som virker fjærende. Horisontale bølgekrefter vil således medføre at innretningen beveger seg frem og tilbake slik at det oppstår relativ dreiebevegelse mellom flytelegemet (1) og det vertikalt langstrakte legemet (2). Fig. 5 and 6 show examples of mooring of the device where reference numbers (12,13) refer to attachment points for mooring lines and reference numbers (14, 15) refer to mooring lines. The device can advantageously be moored to buoys or other devices that have a springy effect. Horizontal wave forces will thus cause the device to move back and forth so that a relative turning movement occurs between the floating body (1) and the vertically elongated body (2).
En annen variant av foreliggende oppfinnelse er å plassere det vertikalt langstrakte legemet (2) slik at dets nederste ende er opplagret på havbunnen eller er forankret til havbunnen. Another variant of the present invention is to place the vertically elongated body (2) so that its lower end is stored on the seabed or is anchored to the seabed.
En ytterligere variant av foreliggende oppfinnelse er å erstatte kammeret (3) med et legeme med høy densitet. A further variant of the present invention is to replace the chamber (3) with a body of high density.
