The single-arm blade and the propeller, which are on two separate hollow shafts (1a,3), are built one behind the other on an assembly shaft (5) or main shaft. The hollow shafts are provided with a gear wheel, each of which meshes with another gear wheel on another assembly shaft (6) or auxiliary shaft, and both the gear wheels are coupled with each other on the other assembly shaft in a torque proof manner. An existing wind power installation is retrofitted with the rotor head.

Description

Die vorliegende Erfindung betrifft einen 3-flügeligen Propeller, dem ein weiterer einarmiger Propellerarm auf gleicher Achse, aber mit eigener Welle vorgebaut ist. Die Hohlwelle ist zweiteilig ausgeführt. Dieser vorgeschaltete Einarm-Flügel (Treiber) läuft je nach Drehzahl mit einer optimalen Umdrehungsnutzung von „9 zu 12".The The present invention relates to a 3-bladed propeller, a another one-armed propeller arm on the same axis, but with its own Wave is pre-built. The hollow shaft is made in two parts. This upstream single-arm wing (Driver) is running depending on the number of revolutions, with an optimum use of revolutions of "9 to 12".

Bei neun (9) Umdrehungen des 3er Propellers macht der Einarm-Flügel zwölf (12) Umdrehungen, das sind 3 Umdrehungen mehr. Dies entspricht einer Leistungssteigerung von 25 % zuzüglich des Ein-Arm-Flügels mit 100 %. In Summe bedeutet das eine Leistungssteigerung von 125 %.at Nine (9) turns of the 3er propeller makes the one-arm wing twelve (12) Turns, that's 3 more turns. This corresponds to one Performance increase of 25% plus of the one-arm wing with 100%. In total, this means a performance increase of 125 %.

Die Umdrehungszahlen sind nicht verbindlich, es könnten sich in der Praxis auch andere Geschwindigkeiten oder Drehzahlen ergeben.The Revolutions are not binding, it could be in practice too other speeds or speeds result.

Aus der DE 101 07 956 A1 ist eine Windkraftanlage bekannt, deren Effizienz dadurch verbessert wird, dass vor oder hinter dem bislang verwendeten Rotor ein weiterer Rotor platziert wird und dieser Rotor eine eigene Antriebswelle besitzt, welche auf der des ersten Rotors drehbar gelagert ist. Die beiden Rotoren arbeiten unabhängig voneinander.From the DE 101 07 956 A1 a wind turbine is known whose efficiency is improved by the fact that in front of or behind the previously used rotor another rotor is placed and this rotor has its own drive shaft which is rotatably mounted on the first rotor. The two rotors work independently of each other.

Aus der DE 29 32 293 A1 ist eine Windkraftanlage mit zwei gegenläufig sich drehenden hintereinander an einem schwenkbaren Gehäuse angeordneten Propellern bekannt, wobei der dem Gehäuse zugewandte Propeller am Ende einer die Rotorwelle umgebenden und den Stator des Generators tragenden Hohlwelle sitzt. Zwischen der Rotorwelle und der Hohlwelle sitzt eine Getriebe-Verbindung, die die beiden Wellen in gegenläufigem Umlauf und in einem konstanten Drehzahlverhältnis hält.From the DE 29 32 293 A1 is a wind turbine with two counter-rotating rotating one behind the other arranged on a pivotable housing propellers known, wherein the housing facing the propeller sits at the end of a surrounding the rotor shaft and the stator of the generator supporting hollow shaft. Between the rotor shaft and the hollow shaft sits a gearbox connection, which keeps the two shafts in opposite circulation and in a constant speed ratio.

Aus der WO 2002/057624 A1 ist eine Windenergieanlage mit einer Hohlwelle für Rotornabe und Generator bekannt.From the WO 2002/057624 A1 is a wind turbine with a hollow shaft for rotor hub and generator known.

Der Erfindung liegt die Aufgabe zugrunde, bestehende Windkraftanlagen mit 3 Flügeln mit Einarm-Rotorblättern nachzurüsten und damit eine Leistungssteigerung zu erzielen.Of the Invention is based on the object existing wind turbines with 3 wings with one-arm rotor blades retrofit and thus to achieve an increase in performance.

Die Erfindung wird nachfolgend anhand der II und III näher erläutert.The invention will be described below with reference to II and III explained in more detail.

II zeigt die Seitenansicht eines Rotor-Getriebes, den Rotorkopf mit den 3 Zahnrädern 1, 1a, 3, 4, den beiden geteilten Hohlwellen 3, 4, einmal für den Propeller 1, dessen Welle hohl ist und hierin die zweite Welle für den Einarm Antrieb 2. In III werden die einzelnen Komponenten des Rotor-Getriebes und das zusammengebaute System dargestellt. Der Einarm-Antrieb 2 läuft wieder in Verbindung mit einem Zahnrad 4. Dabei können die Umdrehungszahlen, die erforderlich sind oder gewünscht werden, eingestellt werden. Der vorgeschaltete Einarm-Flügel 2 (Treiber) läuft je nach Drehzahl mit einer optimalen Umdrehungsnutzung von „9 zu 12". II shows the side view of a rotor gear, the rotor head with the 3 gears 1 . 1a . 3 . 4 , the two split hollow shafts 3 . 4 once for the propeller 1 whose shaft is hollow and here the second shaft for the one-arm drive 2 , In III the individual components of the rotor gearbox and the assembled system are shown. The one-arm drive 2 runs again in conjunction with a gear 4 , The number of revolutions required or desired can be adjusted. The upstream one-arm wing 2 (Driver) runs depending on the speed with an optimal rotation use of "9 to 12".

Hierbei kann es sich um ein stehendes oder ein liegendes Getriebe handeln. Mit Propeller 1 ist immer der Rotor mit einem 3 flügeligen Rotorblatt gemeint. Beim Einarm-Flügel 2 handelt es sich um den neuen zusätzlichen Flügel. Beide Einheiten laufen auf einer gemeinsamen Montagewelle 5 (Hauptwelle). Auf einer weiteren Montagewelle 6 (Nebenwelle) wird das Zahnrad 4 montiert. Der Propeller 1 läuft über eine obere Hohlwelle 1a mit einem einfachen Zahnrad auf der Montagewelle 5. Auf der unteren Hohlwelle 3 ist der Einarm-Flügel 2 angeordnet, dieser ist wieder verbunden mit dem Zahnrad der Hohlwelle 3. Dieses Zahnrad hat zwei Zahnkränze 3, wobei der kleinere obere Zahnkranz 3 mit dem Zahnrad 4 kämmend verbunden ist. Das Zahnrad 1a steht für weitere Getriebeergänzungen zur Verfügung. Durch die Montagewellen 5 und 6 werden diese zu einer unabhängigen Welleneinheit zusammengefügt. Die beiden Hohlwellen 1a, 3 haben unterschiedliche Längen, die untere Hohlwelle 3 ist länger, da diese durch die Welle von 1a geschoben und montiert wird, hierauf kommt der Montagekopf vom Einarm-Flügel 2.This may be a stationary or a horizontal transmission. With propeller 1 is always meant the rotor with a 3-bladed rotor blade. At the one-arm wing 2 it is the new additional wing. Both units run on a common assembly shaft 5 (Main shaft). On another assembly shaft 6 (Nebenwelle) becomes the gear 4 assembled. The propeller 1 runs over an upper hollow shaft 1a with a simple gear on the mounting shaft 5 , On the lower hollow shaft 3 is the one-arm wing 2 arranged, this is again connected to the gear of the hollow shaft 3 , This gear has two sprockets 3 , where the smaller upper sprocket 3 with the gear 4 combing is connected. The gear 1a is available for additional gearbox supplements. Through the mounting shafts 5 and 6 these are put together to form an independent wave unit. The two hollow shafts 1a . 3 have different lengths, the lower hollow shaft 3 is longer, as this is due to the wave of 1a pushed and mounted, then comes the mounting head of the one-arm wing 2 ,

Diese Anlage kann mit ca. 30–40 m langen Rotorblättern gefahren werden. Der Einarm sollte um 10 % länger sein, um mehr Leistung zu bringen, aber auch um Verwirbelungen zu vermeiden und um diese besser abzuleiten.These Plant can with about 30-40 m long rotor blades be driven. The arm should be 10% longer for more power but also to avoid turbulence and to make it better derive.

Jeder Propeller erwirtschaftet seine eigene Energie und speist diese in das Netz ein. Vorteilhaft ist auch, dass die Anlage nicht die Höhe der neuen "Offshore" Anlagen mit Flügellängen von 60 m Länge und einem Gewicht von über 20 Tonnen je Flügel haben muss.Everyone Propeller generates its own energy and feeds it in the network. It is also advantageous that the plant does not match the height of the new "offshore" plants with wing lengths of 60 m in length and a weight of over 20 tons per wing must have.

Auf die jetzigen Anlagen könnte dieser neue Rotorkopf aufgesetzt werden. Bei über 100 % mehr Leistung, mehr Sicherheit und geringeren Baukosten wird dies "neue Genehmigungen" leichter machen. Das zusätzliche Gewicht des Einarm-Rotors dürfte beim heutigen Stand der Technik keine Probleme bedeuten.On the current facilities could this new rotor head will be put on. With more than 100% more power, more Security and lower construction costs will make this "new permits" easier. The extra Weight of the one-arm rotor is likely to Today's state of the art mean no problems.

Wir brauchen mehr Leistung bei den bestehenden Anlagen, um diese weiterhin wirtschaftlich besser betreiben zu können. Ein Rotor mit Doppelkopf, ein 3flg. Propeller und Einarm-Rotor, das könnte Zukunft für die nächsten Jahre sein.We need more power in existing systems to continue this to operate economically better. A rotor with double head, a 3flg. Propeller and single-arm rotor, that could be future for the next few years be.

Um genaue Daten zu haben, gehört diese Aufgabe in die Hände von Spezialisten wie der Uni Bremen, den Enercon-Windkraftbetreibern, Rotec Spezialist für Rotorblätter (Abeking & Rasmussen Bremen).In order to have precise data, this task belongs to specialists such as the University of Bremen, the Enercon wind power operators, Rotec specialist for rotor blades (Abeking & Rasmussen Bremen).
