Abstract

The system has a set of fixed blades forming a twist around axes when actuated by an action of water flow while the flow is stronger than inertia and friction of the system.

Description

Energie opvang systeem voor weinig veranderlijke stromingenEnergy collection system for little changeable currents

Deze uitvinding heeft tot doel om stromingen in het algemeen, en meer bepaald stromingen in rivieren of zeestromingen, efficiënt op te vangen.The present invention has for its object to efficiently collect currents in general, and in particular currents in rivers or sea currents.

Een aantal schoepen wordt op een dergelijke wijze gepositioneerd en onderling verbonden dat er een gesloten ketting wordt gevormd. Deze constructie wordt om minstens één as gemonteerd (zie Fig.1 en Fig.2). In plaats van een grote schoep, kan ook een rij naast mekaar staande schoepen gebruikt worden, eventueel gespatieerd. De bovenste (terugkerende) schoepen komen boven het wateroppervlak, de onderste (aangedreven) schoepen vangen stroming op. De schoepen kunnen gestroomlijnd zijn, of symmetrisch (bij van zin veranderende stromingen).A number of blades are positioned and interconnected in such a way that a closed chain is formed. This construction is mounted on at least one axis (see Fig.1 and Fig.2). Instead of a large blade, a row of adjacent blades can also be used, possibly spaced. The upper (returning) blades rise above the surface of the water, the lower (driven) blades absorb flow. The blades can be streamlined or symmetrical (with changing currents).

Een variante wordt bekomen door de schoepen te vervangen door periodiek doorlatende wanden, beschreven in proces verbaal van indiening van octrooiaanvraag nr BE-2007/511 d.d. 22/10/2007 (Zie Fig.4, Fig.5, Fig.6 ). In tegenstelling tot de uitvoering met vaste schoepen, laat deze uitvoering een opstelling toe die (eventueel) volledig ondergedompeld is, en in een horizontale of verticale positie.A variant is obtained by replacing the blades with periodically permeable walls, described in the official report of filing of patent application no. BE-2007/511 of 22/10/2007 (See Fig. 4, Fig. 5, Fig. 6). Unlike the version with fixed blades, this version allows an arrangement that is (possibly) completely submerged, and in a horizontal or vertical position.

Door de uitvoering aan te passen kan de totale oppervlakte schoep/wand waarop de stroming impact heeft, geoptimaliseerd worden voor elke situatie; het formaat van de schoepen/wanden, alsook hun aantal in de ketting en de totale lengte van de constructie, staan in functie van de stroming (breed/smal, diep/ondiep, traag/snel), en/of het gewenste rendement.By adapting the implementation, the total surface area of the vane / wall on which the flow has an impact can be optimized for every situation; the size of the blades / walls, as well as their number in the chain and the total length of the structure, depend on the flow (wide / narrow, deep / shallow, slow / fast), and / or the desired efficiency.

Fig. 1 en Fig. 2 schetsen als voorbeeld een constructie gebaseerd op een grote schoep.FIG. 1 and FIG. 2 sketches as an example a construction based on a large vane.

Fig. 3 schetst een variante met vlotters en een verankering in de bodem, of aan de oever.FIG. 3 outlines a variant with floats and anchoring in the bottom or on the bank.

Fig. 4 schetst als voorbeeld een constructie gebaseerd periodiek doorlatende wanden, bestaande uit een grote klep. De kleppen kunnen eventueel verzwaard worden om het openen te vergemakkelijken.FIG. 4 illustrates by way of example a construction based on periodically permeable walls consisting of a large valve. The valves can optionally be weighted to facilitate opening.

Fig. 5 schetst een detail van een mogelijke periodiek doorlatende wand met 1 grote klep, of een wand met een rij kleppen, eventueel gespatieerd, naast mekaar.FIG. 5 outlines a detail of a possible periodically permeable wall with 1 large valve, or a wall with a row of valves, possibly spaced, next to each other.

Fig.6 schetst een uitvoering bestaande uit periodiek doorlatende wanden met elk 3 rijen kleppen, en een systeem met 2 assen, verticaal of horizontaal, en lichtjes hellend of schuin.Fig. 6 outlines an embodiment consisting of periodically permeable walls with 3 rows of valves each, and a system with 2 axes, vertical or horizontal, and slightly inclined or sloping.

In een stroming zal door de ongelijkheid tussen doorlatende en niet doorlatende wanden, of in het geval van vaste schoepen door de evidente inwerking van de stroming, een draaibeweging ontstaan rond een of meerdere assen zolang de stroming sterker is dan de traagheid en wrijvingen (uiteraard geminimaliseerd) van het systeem.In a flow, due to the inequality between permeable and impermeable walls, or in the case of fixed blades due to the obvious effect of the flow, a rotational movement will occur around one or more axes as long as the flow is stronger than the inertia and frictions (naturally minimized ) of the system.
