Abstract
Description
Eine Neuorientierung bei der Stromerzeugung bedingt auch die verstärkte Nutzung der Wasserkräfte. Dies ist nur möglich, wenn auch kleine Gefälle bei relativ großen Wassermengen in Flüssen und Meer zu vertretbaren Kos ten pro KW Investitionsvolumen erschlossen werden.A reorientation in power generation also requires increased Use of water power. This is only possible, albeit a small gradient with relatively large amounts of water in rivers and sea to acceptable Kos ten per KW investment volume.
Nur mittels Querstromturbine und der Möglichkeit, den künstlichen Stau, den ein Wasserkraftwerk verursacht, bei Hochwasser durch aufschwimmen der Energieentnahmeeinrichtung kann das Ziel erreicht werden, die Stromer zeugungskosten mittels Wasserkraft wettbewerbsfähig zu machen bei geringstem Eingriff in die Natur.Only by means of a cross-flow turbine and the possibility of the artificial traffic jam, caused by a hydroelectric power plant, in the event of flooding, by floating the Energy extraction device can be achieved, the Stromer To make generation costs competitive by means of hydropower at the lowest Intervention in the nature.
Das Kernstück der Wasserkraftanlage stellt die optimale Kombination aus Schwimmwehr, Querstromturbine und integriertem Rotationsrechen dar. Es besteht aus der Staueinrichtung mit integrierter Turbinenregelklappe, die im Inneren des Turbinenrades (Trommelläufer) angeordnet ist, dem Turbinen laufrad, das ganz oder teilweise in das Arbeitsmedium eintaucht und in einer Fachwerkkonstruktion gelagert ist, sowie zwei Schwimmkörpern, auf die sich die vorgenannte Konstruktion abstützt.The centerpiece of the hydropower plant is the optimal combination Lifeguard, cross-flow turbine and integrated rotary rake consists of the stowage device with integrated turbine control flap is arranged inside the turbine wheel (drum rotor), the turbines Impeller that is fully or partially immersed in the working medium and in one Truss structure is mounted, as well as two floating bodies on which supports the aforementioned construction.
Der in Fließrichtung vordere Schwimmkörper ist als biegesteifer Ponton mit Schaumstoff gefüllt und damit unsinkbar. Er wird beidseitig in U- Profilen im Gerinne so geführt und angeordnet, daß er auch die Funktion des Schwimmbalkens, also die Umleitung von Treibeis und sonst. Schwemmgut zum Bypaß erfüllt.The front floating body in the direction of flow is a rigid pontoon filled with foam and therefore unsinkable. It is Profiles in the channel guided and arranged so that it also functions the floating beam, ie the diversion of floating ice and other floating debris to bypass met.
Der hintere Schwimmkörper, der unter der Fachwerkkonstruktion schwenkbar angeordnet ist, kann mittels Preßluft entleert und durch Ventilumsteuerung wieder geflutet werden und ermöglicht so das Aufschwimmen und Absenken der gesamten Konstruktion. Das Ausschwenken dieses Schwimmkörpers mittels Hydraulik gegenüber der Fachwerkkonstruktion gestattet drei Funktionen:The rear floating body that swivels under the truss structure is arranged, can be emptied by means of compressed air and by valve reversal be flooded again, thus allowing floating and lowering of the entire construction. The swinging out of this float by means of Hydraulics versus the truss construction allow three functions:
- 1. Im abgesenkten Zustand öffnet sich die Schere zwischen Rechenharke und Schwimmkörper und gibt den Bypaß zur Turbine frei zur Schwemmgutentsorgung.1. When lowered, the scissors open between rake and Float and releases the bypass to the turbine for the disposal of debris.
- 2. Bei Ausfall der Preßluft erzeugt das Ausschwenken den Wasserskieffekt und ermöglicht so in Zusammenwirken mit dem Bypaß den Notabfluß des Arbeit wassers.2. If the compressed air fails, swiveling out creates the water ski effect and in cooperation with the bypass enables the emergency drainage of the work water.
- 3. Bei aufgeschwommener Konstruktion und ausgefahrener Schwenkhydraulik ist bei Wartungsarbeiten auch das Gelenk trocken erreichbar und der Ab flußwiderstand wird minimiert.3. With the construction floating and the swing hydraulics extended the joint can be reached dry during maintenance work and the Ab flow resistance is minimized.
Eine Querstromturbineneinheit (Modul), von der auch mehrere parallel arbeitend zu einer Einheit verknüpft sein können, besteht aus einem ge teilten Laufrad mit am Umfang angeordneten Schaufeln (Trommelläufer) - ein umschließendes Gehäuse wird nicht benötigt - und der Leistungsrege lungsklappe, die als Teil der im Laufradinneren angeordneten Stauein richtung um die gemeinsame Achse hydraulisch bewegt werden kann. Die Querstromturbine besitzt am äußeren Umfang mehrere Ringe, die in ihrer Anordung einen Rotationsrechen bilden, der sich gegen eine unten an der Fachwerkkonstruktion befestigten Harke dreht. Die Harke schließt dicht zum hinteren Schwimmkörper ab. Die Schere kann jedoch zur Schwemm gutentsorgung geöffnet werden.A cross-flow turbine unit (module), of which also several in parallel working together to form a unit consists of a ge divided impeller with blades arranged on the circumference (drum rotor) - an enclosing housing is not required - and the power surge flap, which is part of the jam located inside the impeller direction can be moved hydraulically around the common axis. The cross-flow turbine has several rings on the outer circumference, which in their arrangement form a rotary rake against one below the rake attached to the truss structure rotates. The rake closes close to the rear float. The scissors can, however, become a flood waste disposal can be opened.
Die Kraftübertragung zum über der Turbine angeordneten Generator erfolgt mittels Zahnriemen und Getriebe.The power is transmitted to the generator arranged above the turbine by means of a toothed belt and gear.
Die Dichtung zwischen der Konstruktion und dem Gerinne aber auch intern erfolgt gleitend.The seal between the structure and the channel, but also internally takes place smoothly.
Die separate Bypaßentlastungsklappe schließt in einem bestimmten Winkel bereich durch kreisbogenförmige Ausführung der Gerinnesohle in diesem Bereich dicht, damit das vom Schwimmbalken zugeführte Schwimmgut stets ohne großen Arbeitswasserverlust entsorgt werden kann.The separate bypass relief valve closes at a certain angle area through circular arc design of the channel bottom in this Area tight, so that the floating material supplied by the floating beam is always there can be disposed of without great loss of working water.
Die Hilfsaggregate werden in einem neben der Bypaßentlastungsklappe, hochwassersicher angeordnetem, wetterfestem Raum untergebracht. Von hier erfolgt auch die Übergabe des Stromes ans Netz.The auxiliary units are in a next to the bypass relief valve, flood-proof, weatherproof room. From here the electricity is also transferred to the grid.
