Claims (6)

1. Strömungsmaschine zur Verwendung in Unterwasserkraftwerken mit in Strömungs­ richtung angeordneter Laufradachse, auf der ein Schaufelrad (2) umläuft und dessen Rotationsbewegung über ein Getriebe (6) einen Generator (5) antreibt, dadurch ge­ kennzeichnet, dass dem Schaufelrad (2) mindestens ein kleineres weiteres Schaufelrad (1) vorgesetzt ist, so dass erst das kleinere und dann das größere Schaufelrad durchströmt wird und zwi­ schen den Schaufelrädern (1, 2) eine Reibschlussverbindung besteht, die eine Rela­ tivbewegung zwischen den Schaufelrädern (1, 2) zuläßt.1. Turbomachine for use in underwater power plants with an impeller axis arranged in the flow direction, on which a paddle wheel ( 2 ) rotates and whose rotational movement drives a generator ( 5 ) via a gear ( 6 ), characterized in that the paddle wheel ( 2 ) has at least one Smaller additional paddle wheel ( 1 ) is placed so that only the smaller and then the larger paddle wheel is flowed through and between the paddle wheels ( 1 , 2 ) there is a frictional connection which allows a relative movement between the paddle wheels ( 1 , 2 ). 2. Strömungsmaschine nach Anspruch 1, dadurch gekennzeichnet, dass die Schaufelräder (1, 2) auf jeweils einer Hohlwelle (10, 13) gelagert sind, die inein­ ander gesteckt sind und um eine starre Laufradachse rotieren, wobei der Reibschluss zwischen den Hohlwellen (10, 13) besteht und eine Hohlwelle (10, 13) die Rotations­ bewegung zum Getriebe (6) überträgt.2. Turbomachine according to claim 1, characterized in that the paddle wheels ( 1 , 2 ) are each mounted on a hollow shaft ( 10 , 13 ) which are inserted into one another and rotate about a rigid impeller axis, the frictional engagement between the hollow shafts ( 10 , 13 ) and a hollow shaft ( 10 , 13 ) transmits the rotational movement to the transmission ( 6 ). 3. Strömungsmaschine nach Anspruch 2, dadurch gekennzeichnet, dass auf der Hohlwelle (13) des kleineren Schaufelrades (1) ein Reibring (12) angeordnet ist, der den Reibschluss mit der Stirnseite der Hohlwelle (10) bildet.3. Turbomachine according to claim 2, characterized in that on the hollow shaft ( 13 ) of the smaller impeller ( 1 ) a friction ring ( 12 ) is arranged, which forms the frictional engagement with the end face of the hollow shaft ( 10 ). 4. Strömungsmaschine nach Anspruch 1, dadurch gekennzeichnet, dass die Drehzahl des kleinen Schaufelrades (1) größer ist als die des Schaufelrades (2). 4. Turbomachine according to claim 1, characterized in that the speed of the small impeller ( 1 ) is greater than that of the impeller ( 2 ). 5. Strömungsmaschine nach Anspruch 4, dadurch gekennzeichnet, dass die Drehzahl des großen Schaufelrades (2) 30-70% der des kleinen Schaufelrades (1) beträgt.5. Turbomachine according to claim 4, characterized in that the speed of the large paddle wheel ( 2 ) is 30-70% of that of the small paddle wheel ( 1 ). 6. Strömungsmaschine nach Anspruch 1, dadurch gekennzeichnet, dass mehrere Kombinationen von Schaufelrädern (1, 2) nebeneinander angeordnet sind und einen Block (15) bilden.6. Flow machine according to claim 1, characterized in that several combinations of paddle wheels ( 1 , 2 ) are arranged side by side and form a block ( 15 ).
