Abstract

The invention relates to an electric generator having an impeller which is driven by river water, is connected on the output side to the drive shaft of the generator and is mounted on a foundation. It is characteristic of the invention that the impeller 4 and generator 14 are mounted on a pontoon 1, which can be anchored or fixed in the river, in such a way that the impeller 4 dips partially into the river water through an opening 3 in the pontoon 1. <IMAGE>

Description

Die Erfindung betrifft einen elektrischen Generator mit einem flußwasserangetriebenen Schaufelrad, das abtriebsseitig mit der Antriebswelle des Generators verbunden und der auf einem Fundament montiert ist.The invention relates to an electric generator a river water powered paddle wheel that on the output side with the drive shaft of the generator connected and which is mounted on a foundation.

Flußwassergetriebene Schaufelräder zum Antrieb von elektrischen Generatoren werden üblicherweise ortsfest fundamentiert, z. B. in Staumauern oder an Flußufern. Der Nachteil dieser ortsfesten Fundamentierung besteht darin, daß das Schaufelrad nur bei einer bestimmten Wasserhöhe angetrieben wird. Sinkt der Wasserspiegel so weit ab, daß das Schaufelrad nicht mehr in das Wasser eintaucht, ist der Antrieb für den Generator unwirksam. Beim Bau des Assuan-Staudamms hat man z. B. die Wasserverdunstung unterschätzt. Nachdem sich das Staubecken vor dem Damm gefüllt hatte, mußte man feststellen, daß sich der Wasserspiegel auf einem wesentlich niedrigeren Niveau eingependelt hatte als gedacht. Dadurch wird nun die oberste Turbinenreihe vom Wasser nicht mehr erreicht, und die Generatoren wurden nutzlos installiert.River water driven paddle wheels for driving electrical generators are usually stationary founded, e.g. B. in dams or on river banks. Of the The disadvantage of this fixed foundation is that that the paddle wheel only at a certain water level is driven. If the water level drops so far, that the paddle wheel no longer dips into the water, the drive for the generator is ineffective. When building the Aswan dam has z. B. water evaporation underestimated. After the reservoir in front of the dam one had to find out that the Water levels at a much lower level had leveled off as thought. This is now the top row of turbines no longer reached by water, and the generators were installed uselessly.

Der Erfindung liegt nun die Aufgabe zugrunde, den flußwassergetriebenen Antrieb für einen elektrischen Generator derart anzuordnen, daß seine Funktion unabhängig vom Wasserpegel gewährleistet ist. The invention is based on the object river water powered drive for an electric Arrange generator so that its function is independent guaranteed by the water level.  

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß das Schaufelrad und der Generator auf einem im Fluß verankerbaren oder festlegbaren Ponton montiert sind, derart, daß das Schaufelrad durch eine Öffnung in dem Ponton teilweise in das Flußwasser eintaucht. Das Schaufelrad als Antrieb mit dem von ihm angetriebenen elektrischen Generator werden also erfindungsgemäß auf einem schwimmfähigen Fundament, eben dem Ponton, montiert. Der Ponton wird am Ufer festgelegt oder im Flußbett verankert. Das Schaufelrad taucht durch eine Öffnung in dem Ponton teilweise in das fließende Wasser ein und wird durch dessen Bewegung in Umdrehung versetzt. Die Schaufelradwelle ist mit der koaxialen Antriebswelle des elektrischen Generators zu gemeinsamer Drehung verbunden.To solve this problem, the invention suggested that the paddle wheel and the generator be on a pontoon that can be anchored or fixed in the river are mounted such that the paddle wheel through a Opening in the pontoon partially into the river water immersed. The paddle wheel as a drive with that of him So be powered electric generator according to the invention on a floatable foundation, just the pontoon. The pontoon is set on the bank or anchored in the riverbed. The paddle wheel dives through an opening in the pontoon partially in the flowing Water and turns through its movement transferred. The paddlewheel shaft is coaxial with the Drive shaft of the electric generator to common Rotation connected.

Mit der Schaufelradwelle dreht sich also auch die Generatorwelle. Durch ein zwischengeschaltetes Getriebe kann die Drehzahl der Generatorwelle mittels eines Unter- oder Übersetzungsgetriebes zwischen beiden Wellen beliebig eingestellt oder geändert werden.So with the paddle wheel shaft, it also rotates Generator shaft. Through an intermediate gear the speed of the generator shaft can be or transmission gear between the two shafts can be set or changed as required.

Der vom Generator gelieferte Strom kann in üblicher Weise über entsprechende Leitungen in das Stromnetz eingespeist werden. The current supplied by the generator can be in the usual way fed into the power grid via appropriate lines become.  

Durch eine Vielzahl von derartigen (Klein-) Generatoren, die auch auf engstem Raum neben- und/oder hintereinander angeordnet sein können, kann eine beträchtliche Strommenge erzeugt werden, ohne daß hierzu teure und immer seltener werdende fossile Primärenergie benötigt wird. Der elektrische Generator gemäß der Erfindung ist auch nicht abhängig von einer Staumauer, Brücke oder dergleichen ortsgebundenen Bauwerken, sondern kann an beliebiger Stelle im Fluß verankert sein. Der erfindungsgemäße Generator ist auch leicht zugänglich, kann von Schiffen abgeschleppt und an einen beliebigen Ort zur Aufstellung oder Reparatur verbracht werden. Konstruktiver Mehraufwand gegenüber der bisherigen Art der Aufstellung von Generatoren ist nicht erforderlich. Anstelle des festen wird nun ein schwimmfähiges Fundament vorgesehen.Through a variety of such (small) generators, that side by side and / or one after the other even in the smallest of spaces can be arranged can be considerable Amount of electricity are generated without expensive and fossil primary energy is becoming increasingly rare becomes. The electrical generator according to the invention is also not dependent on a dam, bridge or similar local structures, but can be anchored anywhere in the river. Of the generator according to the invention is also easily accessible, can be towed by ships and sent to any Place to be installed or repaired. Additional design effort compared to the previous type the installation of generators is not necessary. Instead of the solid one, there is now a floating foundation intended.

Fig. 2 eine Draufsicht auf den Generator mit Schaufelrad, montiert auf einem schwimmfähigen Ponton. Fig. 2 is a plan view of the generator with a paddle wheel, mounted on a floating pontoon.

Der Ponton 1 enthält Luftkammern 2, die seine Schwimmfähigkeit verursachen. Er hat einen Ausschnitt 3, durch den das Schaufelrad 4 hindurch teilweise in das in Pfeilrichtung 5 fließende Flußwasser 6 eintaucht. Der Ponton 1 ist über Ketten 7 und Anker 8 im Fluß verankert. The pontoon 1 contains air chambers 2 , which cause its buoyancy. It has a cutout 3 through which the paddle wheel 4 is partially immersed in the river water 6 flowing in the direction of the arrow 5 . The pontoon 1 is anchored in the river via chains 7 and anchors 8 .

Das Schaufelrad 4 ist in auf dem Ponton 1 montierten Lagern 9 mit seiner Welle 10 drehbar gelagert und wird durch die Bewegung des Flußwassers 6 in Pfeilrichtung 11 in Umdrehung versetzt.The paddle wheel 4 is rotatably mounted with its shaft 10 in bearings 9 mounted on the pontoon 1 and is rotated by the movement of the river water 6 in the direction of the arrow 11 .

Abtriebsseitig ist die Schaufelradwelle 10 beispielsweise über eine Kupplung 12 und/oder ein nicht dargestelltes Unter- oder Übersetzungsgetriebe mit der Welle 13 des elektrischen Generators 14 verbunden. Der vom Generator 14 erzeugte Strom wird über eine Leitung 15 ins Stromnetz eingespeist.On the output side, the bucket wheel shaft 10 is connected to the shaft 13 of the electrical generator 14 , for example, via a clutch 12 and / or a step-down or step-up gear, not shown. The current generated by the generator 14 is fed into the power grid via a line 15 .
