Abstract
The object of the invention is to provide a water power drive machine which achieves at least the performance features of the turbine, but on the other hand results in a major reduction in the production costs and renders complex regulation superfluous. The present static- pressure machine is a simple sheet-steel construction which consists of a hub 1 whose diameter corresponds to the drop height, as well as blades 2 attached to it, which correspond to the width and height of the normal water-level cross section, so that, on no load, the entire amount of water can flow through without building up. A sheet-steel disc is connected to the hub 1 and to the blades 2 on both sides. This results in a very tough and dimensionally stiff structure. Shaft or axle journals are attached to the hub 1 on the right and left. The openings in the blade curvature, with float flaps 3 located on them, allow the blade chambers to be filled as they enter the built-up water level. <IMAGE>
Description
<Desc/Clms Page number 1>
In der Vergangenheit wurden Wasserräder ausschliesslich als ober-oder unterschlächtige Maschinen gebaut. Der Nachteil dieser Wasserräder war das geringe Schluckvermögen, und daher auch kleine Leistungen, wie dies z. B. aus der US 4, 727. 070 A hervorgeht.
Solche Wasserräder mussten auch freigestellt arbeiten, das heisst, diese Räder durften nicht im Unterwasser eintauchen. Die Verluste wären zu gross geworden.
Ziel dieser Erfindung ist es, ein Laufrad zu schaffen das voll im Unterwasser eintauch und daher auch grosse Wassermengen schlucken kann.
Da dieses Laufrad den gesamten Querschnitt des Gerinnes mit seinen unteren Schaufeln und seiner Habe absperrt, kann man durch Leistungsentnahme (Abbremsen) einen Staupegel vor der Maschine hochfahren, der einerseits der gewünschten Nennleistung, bzw. der vorgegebenen Fallhöhe entspricht. Ein Streichwehr ermöglicht ein abfliessen überschüssiger Wassermengen.
Durch diese Eigenschaft kann die Staudruckmaschine bei grossen Wassermengen und relativ kleinen Fallhöhen eine Turbine nicht nur voll ersetzen, sondern kann durch besonders kostengünstige Bauweise (ca ein zehntel einer Turbine) auch dort noch wirtschaftlich arbeiten, wo eine Turbine wegen zu geringer Fallhöhe nicht einsetzbar ist.
Die erfindungsgemässe Staudruck-Antriebsmaschine, mit den kennzeichnenden Merkmalen des Anspruchs 1, hat demgegenüber den Vorteil, dass diese Maschine im Gegensatz zur Wasserturbine keine aufwendige Regelung benötigt, sondern dass das Drehmoment der Maschine nur durch Staudruck des Wassers auf die untere Schaufel entsteht.
Dieser Staudruck wird dadurch aufgebaut, indem Leistung abgeführt wird, das heisst, die Maschine wird abgebremst und die Habe sowie die untere Schaufel sperren den Durchflussquerschnitt ab. Dadurch füllt sich das Gerinne bis zur von der Leistung vorgegebenen Fallhöhe.
Überschüssige Wassermengen können über ein Streichwehr abfliessen. Da dieses Laufrad immer die vorhandene Wassermenge, mit dem dazugehörigem Staupegel als Wirkleistung fast zur Gänze abgibt, (Verluste ergeben sich nur durch Wasserverlust wegen Luftspalt) kann man mit Wirkungsgrade rechnen, die den von Turbinen übertreffen. Da bei diesem Laufrad Strömungsumkehrungen nicht auftreten, fallen daher Umlenkverluste nicht an. die bei der Turbine durch die Richtungsänderug des Wassers unvermeidlich sind. Dadurch ergibt sich eine Verbesserung des Wirkungsgrades Da die Herstellungskosten dieser Maschine nur ungefähr ein zehntel einer vergleichsweisen Turbine beträgt, ist hierin einer der grössten Vorteile zu sehen.

Es zeigen :
Fig. 1 ein Schema des Laufradkonzeptes
Fig. 2 Querschnitt eines Laufrades mit Nabe (1), Schaufeln (2), und Schwimmerklappe (3)
Fig. 3 Anlage mit 2 Laufräder, Oberwasseransicht
Die Fig. 1 zeigt das Laufrad unter den Betriebszuständen Leerlauf und Last, sowie das Aufstauen des Wassers mit Hilfe der Nabe (1) Das gesamte Laufrad ist aus Stahlblech verschweisst oder verschraubt. Die Schaufeln sind obenvasserseitig gekrümmt, damit unterwasserseitig kein Wasser angehoben wird.
Die Fig. 2 und 3 zeigen ein Laufrad mit gekrümmten Schaufeln (2), und eine oder mehrere Öffnungen mit Schwimmerklappe (3) um die Befüllung der Laufradkammern beim Eintauchen in das Oberwasser ohne nennenswerte Auftriebsveriuste zu ermöglichen.
Bei einem Laufrad mit schräg zur Achse befestigten Schaufeln, erübrigt sich eine Öffnung mit Schwimmerklappe. (3) Die Laufradschaufeln sind bis zu 45 Grad geneigt, sodass weder beim Eintauchen der Laufradschaufeln in das Oberwasser Auftriebsverluste, noch im Unterwasserbereich Wasser angehoben wird.

In the past, waterwheels were built exclusively as over- or undershot machines. The disadvantage of these water wheels was the low swallowing ability, and therefore also small performances, such as this. B. from US 4, 727,070 A.
Such water bikes also had to work freely, which means that these bikes were not allowed to be immersed in the underwater. The losses would have been too big.
The aim of this invention is to create an impeller that is fully immersed in underwater and can therefore swallow large amounts of water.
Since this impeller shuts off the entire cross-section of the channel with its lower blades and its belongings, you can increase the accumulation level in front of the machine by removing the power (braking), which on the one hand corresponds to the desired nominal output or the specified head. A coating weir allows excess water to flow away.
With this feature, the dynamic pressure machine can not only fully replace a turbine with large amounts of water and relatively small heads, but can also work economically thanks to its particularly cost-effective design (approx. One tenth of a turbine) where a turbine cannot be used due to the low head.
The dynamic pressure drive machine according to the invention, with the characterizing features of claim 1, has the advantage that, in contrast to the water turbine, this machine does not require any complex control, but that the torque of the machine only arises from the dynamic pressure of the water on the lower blade.
This dynamic pressure is built up by dissipating power, that is, the machine is braked and the goods and the lower blade block the flow cross-section. This fills the channel up to the drop height specified by the output.
Excess amounts of water can flow off via a weir. Since this impeller always gives off the entire amount of water, with the associated accumulation level, as active power (losses only result from water loss due to air gap), you can count on efficiencies that exceed those of turbines. Since flow reversals do not occur with this impeller, there are no deflection losses. which are inevitable in the turbine due to the change in direction of the water. This results in an improvement in efficiency. Since the production costs of this machine are only about a tenth of a comparative turbine, this is one of the greatest advantages.

ing detailed description explained.
Show it :
Fig. 1 is a schematic of the impeller concept
Fig. 2 cross section of an impeller with hub (1), blades (2), and float flap (3)
Fig. 3 system with 2 impellers, top water view
Fig. 1 shows the impeller under the operating conditions idle and load, and the accumulation of water with the help of the hub (1). The entire impeller is welded or screwed from sheet steel. The blades are curved on the upper water side so that no water is raised on the underwater side.
2 and 3 show an impeller with curved blades (2), and one or more openings with a float flap (3) to allow the impeller chambers to be filled when immersed in the upper water without any significant buoyancy losses.
In the case of an impeller with blades attached at an angle to the axis, there is no need for an opening with a float flap. (3) The impeller blades are inclined up to 45 degrees, so that when the impeller blades are immersed in the headwater, there is no loss of buoyancy or water in the underwater area.
