Description
Die vorliegende Erfindung betrifft eine Vorrichtung, die eine oszillierende Bewegung eines strömungsgünstigen Körpers in einem strömendem Medium, insbesondere Strömungen in Flüssen, Meeren und in der Atmosphäre, so steuert, dass die an dem umströmten Körper angreifenden Kräfte in Verbindung mit der Bewegung des Körpers, eine Energieübertragung zwischen dem strömenden Medium und der Vorrichtung bewirken. Die bekannten Wasserkraftanlagen, wie Wasserräder und Wasserturbinen, erfordern ein ausreichendes Gefälle, um eine wirtschaftliche Energieübertragung zu ermöglichen. Dies setzt in der Regel geeignete geographische Verhältnisse voraus und ist verbunden mit dem Aufstau des Wassers durch Dämme. Die vorliegende Erfindung nutzt dagegen die kinetische Energie des strömenden Wassers. Somit können Staudämme mit weitreichenden Eingriffen in die Landschaft vermieden werden.The present invention relates to a device which controls an oscillatory movement of a streamlined body in a flowing medium, in particular flows in rivers, seas and in the atmosphere, so that the forces acting on the body flowing around in connection with the movement of the body Effect energy transfer between the flowing medium and the device. The known hydropower plants, such as water wheels and water turbines, require a sufficient gradient in order to enable an economical energy transfer. This usually requires suitable geographic conditions and is connected with the damming of the water by dams. By contrast, the present invention utilizes the kinetic energy of the flowing water. Thus, dams can be avoided with far-reaching interventions in the landscape.
Bei asymmetrischen Körpern oder symmetrischen Körpern, die gegenüber ihrer Symmetrieachse asymmetrisch angeströmt werden, entstehen durch die Umströmung Kräfte, die zur Energieübertragung genutzt werden können. Werden diese Körper in Richtung der am Körper angreifenden Kräfte bewegt, findet eine Energieübertragung vom strömenden Medium auf den Körper statt, der seinerseits diese Energie an die ihn steuernde Vorrichtung abgibt. Bei einer den angreifenden Kräften entgegen gerichteten Bewegung findet eine Übertragung von Energie von der steuernden Vorrichtung über den umströmten Körper auf des strömende Medium statt. Wird der umströmte Körper auf und ab bewegt, ist eine Anpassung der angreifenden Kräfte erforderlich, um die gewünschte Richtung der Energieübertragung zu erzielen. Die zeitliche Zuordnung der periodischen Auf- und Abwärtsbewegung des Körpers zum periodischen Wechsel der angreifenden Kräfte ist somit maßgeblich für die Richtung der Energieübertragung.In the case of asymmetric bodies or symmetrical bodies, which are flowed asymmetrically with respect to their axis of symmetry, the flow creates forces that can be used to transfer energy. When these bodies are moved in the direction of the forces acting on the body, a transfer of energy from the flowing medium to the body takes place, which in turn delivers this energy to the device controlling it. In a movement opposing the attacking forces, transfer of energy from the controlling device to the flowing medium takes place over the circulating body. If the flow around the body is moved up and down, an adaptation of the attacking forces is required to achieve the desired direction of energy transfer. The temporal assignment of the periodic upward and downward movement of the body to the periodic change of the attacking forces is thus decisive for the direction of the energy transfer.
Obwohl nur wenige technische Anwendungen des beschriebenen Prinzips existieren, sind Schriften bekannt, in denen die Funktionsweise einer oszillierende Tragfläche zur Energiegewinnung beschrieben wird. In der Veröffentlichung von K. Jones, M. F. Platzer und S. Davids: „Oscillating-Wing Power Generator”, erschienen in: Proceedings of the 3rd ASME/JSME Fluids Engineering Conference July 18–23, 1999, als Beitrag mit der Nummer FEDSM99-7050, wird ein Mechanismus zur Energieübertragung von einer Gewässer strömung an einen oszillierenden Flügel vorgestellt und in seiner Funktionsweise theoretisch und experimentell analysiert. Der Flügel führt dabei eine lineare Auf- und Abwärtsbewegung durch, die durch Schienen geführt wird. Über Gestänge, Kipphebel und Schwingarme wird dieser Bewegung eine Drehung des Flügels überlagert.Although only a few technical applications of the described principle exist, writings are known in which the operation of an oscillating wing is described for energy. In the publication by K. Jones, MF Platzer and S. Davids: "Oscillating-Wing Power Generator", published in: Proceedings of the 3rd ASME / JSME Fluid Engineering Conference July 18-23, 1999, as a contribution with the number FEDSM99- 7050, a mechanism for energy transfer from a stream of water to an oscillating wing is presented and analyzed in its functioning both theoretically and experimentally. The wing performs a linear up and down movement, which is guided by rails. About linkage, rocker arms and swing arms this movement is superimposed on a rotation of the wing.

In den bekannten Vorrichtungen werden zum Teil elektromechanische oder hydraulische Komponenten zur Steuerung der Tragfläche eingesetzt, während in einigen anderen offenbarten Erfindungen die Tragflächen durch Schienen parallel geführt werden. Zum Teil weisen sie gegeneinander gleitende Verbindungselemente auf und in einigen Darstellungen sind keine Angaben zur Steuerung der Tragflächenbewegung enthalten. Die vorliegende Erfindung beschreibt demgegenüber einen Mechanismus, der mit wenigen mechanischen Komponenten eine derartige oszillierende Bewegung realisiert.In the known devices partly electromechanical or hydraulic components are used to control the wing, while in some other disclosed inventions, the wings are guided in parallel by rails. In part, they have mutually sliding fasteners and in some representations, no information is included to control the wing movement. In contrast, the present invention describes a mechanism that realizes such an oscillating movement with a few mechanical components.
Die der Erfindung zugrunde liegende Aufgabe besteht darin, die Bewegung der umströmten Tragfläche, die sich aus Auf-und Abwärtsbewegungen und einer überlagerten Drehung zusammensetzt, mit Hilfe einer mechanischen Vorrichtung zu realisieren. Im Hinblick auf eine wirtschaftliche Lösung ist die Erfindung durch einen einfachen Aufbau mit wenigen Bauteilen gekennzeichnet. Die Bewegung der Tragfläche wird in der Erfindung durch Kurbeltriebe und geeignete Verbindungselemente erreicht.The object underlying the invention is to realize the movement of the flow around the wing, which is composed of up and down movements and a superimposed rotation, with the aid of a mechanical device. With regard to an economical solution, the invention is characterized by a simple construction with few components. The movement of the support surface is achieved in the invention by crank mechanisms and suitable connecting elements.
