Abstract

Es wird wie im Ausführungsbeispiel in Fig. 1 ein Bandkraftwerk, welches die kinetische Energie des strömenden Gewässers mittels auf Kettenstreben(12) montierten Schaufeln (10) über Ketten (7) und Wellen (B) und (15) mit Kettenrädern (9) durch einen Generator im Generatorhaus (6) in Elektrizität umwandelt, beschrieben. Um gegenüber dem Stand der Technik vorteilhafte Anströmungsbedingungen der Schaufel gewährleisten zu können, wird vorgeschlagen dass die Schaufeln (10) mit mindestens einer Abstützung (11) versehen werden, was ein Wegklappen aus der Strömung verhindert und damit eine konstante und leistungsstarke Anströmung sicherstellt.It is as in the embodiment in Fig. 1, a band power plant, the kinetic energy of the flowing water by means of chain struts (12) mounted blades (10) through chains (7) and shafts (B) and (15) with sprockets (9) a generator in the generator house (6) converts into electricity, described. In order to be able to ensure advantageous inflow conditions of the blade relative to the prior art, it is proposed that the blades (10) be provided with at least one support (11), which prevents folding away from the flow and thus ensures a constant and powerful flow.

Description

Beschreibung [0001] Die Erfindung bezieht sich auf ein Bandkraftwerk, insbesondere zur Generierung vonElektrizität in strömenden Gewässern ohne bauliche Maßnahmen am Fluss und den damitverbundenen Umwelteingriffen.Description The invention relates to a belt power plant, in particular for generating electricity in flowing waters without structural measures on the river and the associated environmental interventions.

[0002] Der Stand der Technik für Schaufeln in Strömungskraftwerken beschreibt sich, wie imPatent GB 2322347A gezeigt, durch an zwei Riemen befestigten Schaufeln, welche die Strö¬mung des fließenden Wassers nutzen, um zwei Wellen über Riemenscheiben anzutreiben undmit einem Generator, welcher über einen Riemen mit einer der beiden Wellen verbunden ist,elektrische Energie zu erzeugen.The state of the art for blades in flow power plants, as shown in patent GB 2322347A, is described as having two belt-mounted blades which use the flow of flowing water to drive two shafts via pulleys and a generator connected via a belt Belt connected to one of the two shafts to generate electrical energy.

[0003] Als nachteilig erweist sich die fehlende Abstützung der Schaufeln, was durch die Unde¬finierte Richtung der Strömung und durch die ungleichmäßige Krafteinwirkung auf die Schaufelndurch die Strömung zu einem Verdrehen der Schaufeln führen kann und damit einen Stillstanddes Kraftwerkes zur Folge hat. Das Patent GB 308132 A unterscheidet sich zum angemeldetenGegenstand durch zwei Trommeln oder Rädern anstatt Kettenrädern, die Schaufeln sind dreh¬bar gelagert und nicht gegen die Strömung abgestützt. Auch in US 3927330 A ist keine Abstüt¬zung an den Schaufeln zur Stabilisierung in der Strömung zu erkennen.A disadvantage is the lack of support of the blades, which can lead by the Unde¬finierte direction of flow and the uneven force on the blades through the flow to a rotation of the blades and thus has a stoppage of the power plant result. The patent GB 308132 A differs from the registered article by two drums or wheels instead of sprockets, the blades are rotatably mounted and not supported against the flow. Also in US 3927330 A no Abstützzung on the blades to stabilize in the flow can be seen.

[0004] Der Erfindung liegt demnach die Aufgabe zu Grunde, einen Bandantrieb so auszugestal¬ten, dass eine Verdrehung der Schaufel durch die Anströmung verhindert wird, damit eineständige und konstante Anströmung der Schaufel sichergestellt wird und damit eine hohe undkonstante Leistung erzeugt werden kann.The invention is therefore based on the object, a belt drive ausestal¬ten so that a rotation of the blade is prevented by the flow, so that a constant and constant flow of the blade is ensured and thus a high and constant power can be generated.

[0005] Die Aufgabe wird dadurch gelöst, dass eine oder mehrere an den Schaufeln 10 fixier¬tein) Abstützung(en) 11 die Schaufeln 10 stabil in der Strömung halten, wodurch die Anströ¬mung konstant und gleichmäßig erfolgt und ein Verdrehen verhindert wird.The object is achieved in that one or more on the blades 10 fixier¬tein) support (s) 11, the blades 10 hold stable in the flow, whereby the Anströ¬mung is constant and uniform and twisting is prevented.

[0006] In den Zeichnungen ist der Erfindungsgegenstand beispielsweise dargestellt. Es zeigendie [0007] Fig. 1 und die Fig. 2 den Erfindungsgegenstand in einer Ansicht von Oben und in einer isometrischen Ansicht.In the drawings, the subject invention is illustrated, for example. FIG. 1 and FIG. 2 show the subject invention in a top view and in an isometric view. FIG.

[0008] Gemäß dem dargestellten Ausführungsbeispiel besteht ein Bandkraftwerk aus einemRahmen 4, welcher die Strömungsleitung, bestehend aus einem Kanal 2, einem sich verjüng¬enden Eintrittsquerschnitt 1 und einem optionalen Diffusor 3, beinhaltet. Im Mittelpunkt derErfindung steht der Antrieb, welcher aus auf Kettenstreben 12 montierten Schaufeln 10, welcheauf Ketten 7 fixiert sind, besteht. Die Schaufeln 10 sind auf Kettenstreben 12 montiert undbeinhalten eine oder mehrere Abstützungen 11, welche die Schaufel 10 in der Strömung halten.Eine der zwei Wellen 8 und 15 überträgt über Kettenräder 9 die Leistung an einen Generator imGeneratorhaus 6. Am Einfluss des Kraftwerkes wird ein Intrusionspräventionssystem 13 mon¬tiert, um sperrige Güter aus dem Fluss am Eindringen in die Mechanik zu hindern. An Ösen 5kann das Kraftwerk mit einem Kran in das Fließgewässer gehoben werden, gleichzeitig bildendiese auch die Angriffspunkte für die Fixierung im Fluss.According to the illustrated embodiment, a band power plant consists of a frame 4, which includes the flow line, consisting of a channel 2, a tapered inlet cross-section 1 and an optional diffuser 3. The focus of the invention is the drive, which consists of mounted on chain stays 12 blades 10, which are fixed on chains 7. The blades 10 are mounted on chain stays 12 and include one or more supports 11 which hold the blade 10 in the flow. One of the two shafts 8 and 15 transmits power via sprockets 9 to a generator in the generator house 6. The influence of the power plant becomes an intrusion prevention system 13 mon¬tiert to prevent bulky goods from the river from entering the mechanics. At eyelets 5, the power plant can be lifted into the watercourse with a crane, at the same time these also constitute the points of application for the fixation in the river.
