Description

Een vaarbare getijdenstroom turbinemuur energiecentrale.A navigable tidal current turbine wall power plant.

De uitvinding heeft betrekking op het winnen van groene energie door middel van losse turbines geplaatst in een frame 5 (de muur) welke de getijdenstroom (eb en vloed werking) omzetten in energie. Deze manier van schone energiewinning is compact en relatief makkelijk te (ver)plaatsen.The invention relates to the generation of green energy by means of separate turbines placed in a frame 5 (the wall) which converts the tidal current (ebb and flood operation) into energy. This method of clean energy extraction is compact and relatively easy to relocate.

De turbine is een oud principe van één of twee schroeven, 10 in een buis, welke in de containerachtige box geplaatst is. Achter één of tussen twee schroeven is de elektromotor geplaatst. De schroeven, liefst van kunststof (in verband met het rendement), zijn krap in de buis geplaatst. Aan de voor en de achterzijde loopt de buis uit als een trechter welke ook rendement verhogend 15 werkt. In plaats van een schroef kan ook een effectief wormwiel gebruikt worden.The turbine is an old principle of one or two screws, in a tube, which is placed in the container-like box. The electric motor is placed behind one or between two screws. The screws, preferably made of plastic (because of the efficiency), are placed tightly in the tube. At the front and the rear, the tube runs out like a funnel, which also increases efficiency. An effective worm gear can also be used instead of a screw.

Fig. 1 (-3). Dit figuur is een voorbeeld van een dwarsdoorsnede van één schip met daaronder een frame voor 20 drie turbines waarvan de middelste is gevuld met een turbine -containerbox. De schroeven (a) zijn bevestigd door middel van een as (b) die de elektromotor (c) aandrijft, welke met een steun (d) in een buis (e) is bevestigd. Het uiteinde van de buis (e) sluit door middel van een trechtervorm(f) aan op de containerbox (g). 25 Het frame (h) en de containerbox vallen hier samen. Tevens zijn er (i) draagschotten die de buis aan de containerbox bevestigen in verband met de stevigheid. De containerbox wordt in het frame (h) ter plaatse aangebracht of vervangen bij reparatie. De afmetingen van het frame (de turbinemuur) bepalen de grootte en 30 het aantal turbines en zo ook de energieopbrengst. De stroom van de elektromotor (c) zal via een kabel (j) door één van de steunen (d) onder de buis (e) naar het uiteinde van de trechter (f) uit de containerbox (g) en gaat buiten langs met een stroomkabel (j) naar een schakelkast (k) op het schip/ponton (1) worden geleid.FIG. 1 (-3). This figure is an example of a cross-section of one ship with below it a frame for three turbines, the middle of which is filled with a turbine container box. The screws (a) are fixed by means of a shaft (b) which drives the electric motor (c), which is fixed in a tube (e) with a support (d). The end of the tube (e) connects to the container box (g) by means of a funnel shape (f). The frame (h) and the container box coincide here. There are also (i) support partitions that attach the tube to the container box in connection with its robustness. The container box is installed in the frame (h) on site or replaced during repair. The dimensions of the frame (the turbine wall) determine the size and the number of turbines and thus also the energy yield. The current from the electric motor (c) will flow via a cable (j) through one of the supports (d) under the tube (e) to the end of the funnel (f) from the container box (g) and will go outside with a power cable (j) to a switch box (k) on the ship / pontoon (1).

35 Om zo verder te worden getransporteerd naar de vaste wal. De 0 3 4 9 5 2 2 punten (m) zijn kabel- bevestigingspunten waaraan het schip verankerd ligt. De pijlen (n) geven de getijdenstroom richting aan. De waterlijn wordt aangegeven door (o). De vormgeving van figuur 1. is een grove indicatie om een idee te geven van de 5 werking van de uitvinding.35 To be transported further in this way to the mainland. The 0 3 4 9 5 2 2 points (m) are cable fixing points to which the ship is anchored. The arrows indicate the tidal current direction. The waterline is indicated by (o). The design of figure 1. is a rough indication to give an idea of the operation of the invention.

Fig. 2.(-3). Is het onderwater vooraanzicht van het frame (h) dat geschikt is voor drie containerbox- turbines waarbij de middelste is geplaatst. Waarbij de schroef (a), de 10 trechtervorm (f), de anker -kabelpunten (m), drijvend lichaam (1) en de waterlijn (o) overeenkomen met figuur 1.(3.).FIG. 2 (- 3). Is the underwater front view of the frame (h) that is suitable for three container box turbines with the middle one positioned. The screw (a), the funnel shape (f), the anchor cable points (m), the floating body (1) and the water line (o) correspond to figure 1. (3.).

Fig. 3.(-3)Dit figuur (een onderwater beeld) is een voor of achter aanzicht van de turbinemuur geplaatst tussen twee 15 drijvende objecten (a). Het frame (b) met daarin de 15 geplaatste containerbox- turbines. De anker kabelbevestigingspunten (c). Punt (o) geeft de waterlijn aan en (e) de zeebodem. De afmetingen zijn schetsmatig en geven een beeld van een omvang van de uitvinding.FIG. 3. (- 3) This figure (an underwater image) is a front or rear view of the turbine wall placed between two floating objects (a). The frame (b) with the container box turbines placed therein. The anchor cable attachment points (c). Point (o) indicates the waterline and (e) the seabed. The dimensions are sketchy and give an impression of a scope of the invention.

Claims (3)

1. De uitvinding is een op getijdenstroom werkende energiecentrale op het gebied van groene stroom. De muur (als 5 hij gevuld is met turbines) oftewel het frame (als hij leeg is) wordt gekenmerkt door zijn variabele grootte en toepasbaarheid in vele vormen. De muur is hierbij bevestigd aan (een) drijvend(en) lichaam waarbij de muur haaks staat op de eb en vloed stroming en vast verankert blijft liggen.1. The invention is a green power plant operating on tidal power. The wall (if it is filled with turbines) or the frame (if it is empty) is characterized by its variable size and applicability in many forms. The wall is hereby attached to (a) floating (s) body whereby the wall is perpendicular to the ebb and flow and remains firmly anchored. 2. Ook kenmerkt de muur/het frame (voortgaand op conclusie 1.) zich door zijn bruikbaarheid, doordat het bij onderhoud en of reparatie de energiecentrale gewoon kan doordraaien en de niet goed functionerende turbinebox individueel uit het frame geschoven kan worden, bijvoorbeeld 15 door middel van een toepasbare hijsinrichting. Tevens bestaat de mogelijkheid om de muur in zijn geheel of in delen hydraulisch boven water te hijsen, in of tussen het/de drijvende licha(a)m(en), en zo de turbines te verwisselen. Tussen eb en vloed is er een periode van een uur waarbij er zeer weinig 20 stroming is. Deze periode kan worden benut als onderhoud en of reparatiemoment. De nieuwe turbine zal na plaatsing direct werkzaam zijn.2. The wall / frame (continuing to claim 1.) is also characterized by its usefulness in that it can simply rotate the power plant during maintenance and / or repair and the malfunctioning turbine box can be pushed out of the frame individually, for example by by means of a suitable hoisting device. It is also possible to hydraulically hoist the whole or parts of the wall above water, in or between the floating body (s), and thus exchange the turbines. Between ebb and flow there is a period of one hour with very little current. This period can be used as maintenance and / or repair moment. The new turbine will be operational immediately after installation. 3. Voorts kenmerkt het frame (voortgaand op conclusie 1. + 2.) zich door zijn mobiele aspect. Als de muur leeg is en de 25 turbines aan dek van het drijvende lichaam staan, heeft het frame relatief weinig weerstand in het water, waardoor het relatief makkelijk te verplaatsen is over grote afstanden. Na het plaatsen van de turbines en het verankeren kan er direct stroom worden gewonnen mits er getijdestroom loopt. 30 35 0349523. Furthermore, the frame (based on claim 1. + 2.) is characterized by its mobile aspect. When the wall is empty and the turbines are on deck of the floating body, the frame has relatively little resistance in the water, making it relatively easy to move over large distances. After the turbines have been installed and anchored, electricity can be extracted immediately if there is tidal current. 30 35 034952
