Description
Wasserwehre dienten schon immer zur Wasserstandsregelung in Fließgewässern und zur meist damit verbundenen Energiegewinnung durch Wasserräder oder Turbinen. Mit den Dämmen und Staustufen entstanden zugleich Hindernisse für die Schiffahrt. Heutige z.B. Pelton- und Francis-Turbinen nutzen die Wasserenergie derart effizient, daß zur Zeit hierzulande die Möglichkeiten der Nutzung der Energie aus aufgestautem Wasser als nahezu erschlossen gelten.weirs have always been used to regulate the water level in streams and for the most associated with energy production by water wheels or Turbines. With the dams and barrages created at the same time obstacles to shipping. Today's e.g. Pelton and Francis turbines use water energy so efficiently, that to Time in this country the possibilities the use of energy from pent-up water as near-exploited be valid.
Anders verhält es sich mit der Nutzung von Wasserkraft in Fließgewässern.Different behave It deals with the use of hydropower in streams.
Es wurde angestrebt, die vergleichsweise geringe Leistung herkömmlicher Wasserräder infolge deren geringen Beaufschlagungsgrades dadurch zu erhöhen, daß das Wasserrad ersetzt wurde durch Vorrichtungen mit horizontal in Stromrichtung verlaufenden schaufeltragenden Ketten.It was sought, the comparatively low power conventional waterwheels as a result of their low degree of impact thereby increase that the waterwheel has been replaced by devices with horizontally in the flow direction running shovel-carrying chains.

eintauchend in Stromrichtung hintereinander her, während die übrigen Schaufeln

transportiert werden müssen. (z.B.
Da jedoch die voranlaufenden Schaufeln wegen ihrer auf Null absinkenden Relativgeschwindigkeit zum Wasser zwischen den Schaufeln (abgesehen von Randwirbeln und geringem Schwerkrafteinfluß) kaum noch Vortrieb erzeugen, erfüllten sich die Leistungserwartungen an solche Vorrichtungen nicht in gewünschtem Maße.There however, the leading blades because of their sinking to zero Relative speed to the water between the blades (apart marginal vortices and low gravity influence) barely generate propulsion, fulfilled the performance expectations of such devices are not in the desired Dimensions.
Bislang wird die kinetische Energie strömender Gewässer kaum energietechnisch verwertet.So far the kinetic energy is flowing waters hardly exploited energy-technically.
Hier setzt die der Anmeldung zugrunde liegende Vorstellung an.Here implements the idea underlying the application.
Aufgabe der vorliegenden Erfindung ist es, für bestehende Fließgewässer eine weitere Möglichkeit für den Energieaustausch zu eröffnen ohne Staustufen und/oder herkömmliche Turbinen/Wasserräder.task The present invention is for existing rivers a another possibility for the To open up energy exchange without barrages and / or conventional Turbine / water wheels.
Diese Aufgabe wird mit einer Vorrichtung nach dem Anspruch 1 gelöst.These The object is achieved with a device according to claim 1.
Deutliche Verbesserungen gegenüber herkömmlichen Vorrichtungen mit verketteten Schaufeln zur Nutzung der Strömungsenergie des Wassers ergeben sich dadurch, daß alle quer zur Hauptströmung des Wassers umlaufenden Schaufeln, bis auf die gerade wendenden Schaufeln, wirksam beaufschlagt werden und die Leistung der gesamten Vorrichtung mit der Anzahl und Größe der Schaufeln tatsächlich ansteigen kann.significant Improvements over usual Devices with linked blades for the use of flow energy the water result from the fact that all transverse to the main flow of Water circulating blades, except for the just turning blades, be effectively applied and the performance of the entire device with the number and size of the blades indeed can rise.
Durch Energieentnahme oder Energiezufuhr erscheint auch eine energetische Regulierung des Wasserspiegels von Fließgewässern in Bezug auf Hochwasser oder Dürre in gewissem Umfang möglich, da solche Vorrichtungen die Strömung nicht unerheblich beeinflussen können.By Energy extraction or energy intake also appears an energetic Regulation of the water level of rivers in relation to floods or drought to some extent possible, because such devices affect the flow can not influence significantly.
Es wird nun ein Beispiel einer Ausführung des erfindungsgemäßen Wendeschaufelwehrs beschrieben (in Verbindung mit der Bezugszeichenliste zu den Zeichnungen).It will now be an example of an execution of the Reversing blade weir according to the invention described (in conjunction with the list of reference numerals to the drawings).

In den Wendekammern schwenkt das hintere Lager mitsamt der Schaufelhinterkante um die virtuelle Achse durch die Lager der Vorderkante auf die andere Seite, bevor es in die Gegenbahn gleitet und so selbsttätig die geeignete Schaufelanstellung zur Strömung gewährleistet.In the turning chambers pivots the rear bearing together with the blade trailing edge around the virtual axis through the bearings of the leading edge to the other Page, before it slides into the opposite direction and so automatically the ensures appropriate blade position to the flow.
