Der vorliegenden Erfindung liegt das Problem zugrunde, den Wirkungsgrad einer Freistrom-Turbinenanlage der einleitend angegebenen Art zu steigern und die Strömungsverhältnisse innerhalb der Turbine bei gleichzeitig einfacher konstruktiver Ausführung zu optimieren.The present invention is based on the problem to increase the efficiency of a free-flow turbine system of the type mentioned in the introduction and to optimize the flow conditions within the turbine at the same time simple structural design.
Die erfindungsgemäße Turbinenanlage zeichnet sich dadurch aus, daß die beiden Gehäuse über Streben mit einem gemeinsamen, zentral angeordneten Schwimmkörper verbunden sind, der sich entgegen der Strömungsrichtung über die Gehäuse hinaus erstreckt und an seinem vorderen Ende ein Wasserleitblech trägt, das mit Gerinneboden-Verankerungsmitteln und mittels einer Vielzahl von Streben über Seilgitter mit dem Stirnrand der Gehäuse verbunden ist.The turbine system according to the invention is characterized in that the two housings are connected by struts with a common, centrally arranged float, which extends against the flow direction beyond the housing and carries at its front end a water baffle, which with channel bottom anchoring means and means a plurality of struts via cable grille is connected to the front edge of the housing.
Nach einem weiteren Erfindungsmerkmal ist auf der Achse jeder Axialturbine eine Strömungsschnecke montiert, welche einen Generator antreibt. Ferner sind vorzugsweise an der Außenseite der Diffusorringe Wasserleitelemente angeordnet.According to a further feature of the invention, a flow screw is mounted on the axis of each axial turbine, which drives a generator. Furthermore, water guide elements are preferably arranged on the outside of the diffuser rings.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnungen näher erläutert. Es zeigen schematisch:
Gemäß
Die beiden Gehäuse
Die Doppelturbinenanlage erzeugt beispielsweise über zwei 90 kW Generatoren 180 kW elektrischen Strom.For example, the twin-turbine system generates 180 kW of electrical power via two 90 kW generators.
Es versteht sich für den Fachmann, daß das geschilderte Ausführungsbeispiel im Rahmen der Erfindung verschiedentlich abgewandelt werden kann, z. B. was die Ausbildung des Schwimmkörpers und seine Verbindung mit den Turbinengehäusen betrifft.It is understood by those skilled in the art that the described embodiment can be modified variously in the context of the invention, z. As regards the formation of the float and its connection to the turbine housings.
