Abstract

The device has laminar elements joined by one or more mutually parallel closed traction elements (belt, cord, chain) in a freely oscillating manner with the range of oscillations at least partly limited by a stop.

Description

Bei herkömmlichen Wasserrädern ist jeweils nur ein geringer Teil der Schaufeln mit dem Wasser in Kontakt. Die beschriebene Erfindung vergrößert diesen Anteil, in dem diese Schaufeln mit einem über zwei Rollen geführten Band, Seilen oder Ketten beweglich befestigt sind.at usual waterwheels In each case, only a small part of the blades in contact with the water. The described invention enlarges this Proportion in which these blades with a guided over two rolls of tape, Ropes or chains are movably attached.

Das strömende Medium, z.B. Wasser übt einen Druck auf die Schaufeln aus. Ein begrenzendes Element (Anschlag) verhindert, dass der Anstellwinkel der Schaufeln zum Band größer als 90° wird. Die Schaufeln ziehen das Band in Strömungsrichtung. Nach der Richtungsumkehr des Bandes werden die Schaufeln durch die Schwerkraft an das Band gedrückt und verursachen somit nur einen kleinen Strömungswiderstand gegen die Luft. Diese Differenz des Strömungswiderstands kann nun genutzt werden, um Arbeit zu verrichten. (1)The flowing medium, eg water exerts a pressure on the blades. A limiting element (stop) prevents the angle of attack of the blades to the belt is greater than 90 °. The blades pull the tape in the direction of flow. After the reversal of direction of the belt, the blades are pressed by gravity to the belt and thus cause only a small flow resistance to the air. This difference in flow resistance can now be used to do work. ( 1 )

Auch wenn das Schaufelband senkrecht zur Strömungsrichtung im strömenden Medium angeordnet wird, kann damit Energie gewonnen werden. In diesem Fall sind die Begrenzungselemente anders einzustellen. Die Schaufeln werden dann durch die Strömung zur Seite abgedrängt, vergleichbar mit einem kreuzenden Segelboot.
(2)Even if the blade band is arranged perpendicular to the flow direction in the flowing medium, so that energy can be obtained. In this case, the boundary elements are set differently. The blades are then pushed aside by the flow, similar to a cruising sailboat.

Wechselt die Strömungsrichtung häufig, so kann mit einem ringförmigen System, welches richtungsinvariant ist, Energie aus der Strömung gewonnen werden. Eine mögliche Anordnung zeigt 3.If the direction of flow changes frequently, energy can be gained from the flow with an annular system which is direction-invariant. A possible arrangement shows 3 ,

Solch ein Schaufelband ist auch als Schiffsantrieb geeignet. Vorteilhaft ist hier, dass die Verwirbelung geringer ist als bei einer Schiffsschraube, sensible Uferbereiche werden somit weniger belastet. Hierbei wurde ein Anschlag mittels einer Rolle gewählt, die die Schaufeln beim Ziehen durch das Wasser senkrecht stellen. Eine mögliche Anordnung zeigt 4.Such a blade band is also suitable as a ship propulsion. It is advantageous here that the turbulence is less than in a ship's propeller, so sensitive bank areas are thus less stressed. In this case, a stop was selected by means of a roller, which make the blades vertical when pulled through the water. A possible arrangement shows 4 ,
