Die Erfindung betrifft eine Windkraftanlage. The invention relates to a wind turbine.
Windkraft wird nach dem derzeitigen Stand der Technik ausschließlich von Windrädern genützt, die durch unterschiedliche Windzonen streichen und nur einen Durchschnittswert der Windstärke verwerten. Obwohl die Bevölkerung die Windenergie befürwortetet, empfinden viele die Propeller im Landschaftsbild als störend. According to the current state of the art, wind power is used exclusively by wind turbines which pass through different wind zones and only use an average of the wind force. Although the population advocates wind energy, many find the propellers in the landscape disturbing.
Der Savoniusrotor wurde bisher nicht genützt, weil er in der Leistung schwächer ist. The Savoniusrotor has not been used because it is weaker in performance.
Aus der AT 513170 A1 ist eine Windkraftanlage mit einem zweiteiligen Mast, dessen Oberteil mittels eines Elektromotors gegenüber dem unterteil verdreht werden kann, bekannt geworden. Weiters ist es aus der AT 513170 A1 bekannt geworden, die Leistung des Savoni- usrotors durch seine Verwendung als Vertikalrotor, der mit einem Windleitsystem ausgestattet ist, entscheidend zu verbessern. From AT 513170 A1 a wind turbine with a two-part mast, whose upper part can be rotated by means of an electric motor relative to the lower part, has become known. Furthermore, it has become known from AT 513170 A1 to decisively improve the performance of the savoni-usotor by its use as a vertical rotor equipped with a wind-guiding system.
Eine Windkraftanlage mit einem fix mit dem Boden verankerten Mast, an dem auskragende Träger mittels Seilen abgespannt sind, ist aus der DE 102005021390 A1 bekannt geworden. A wind power plant with a mast fixed to the ground, on which projecting beams are braced by means of cables, has become known from DE 102005021390 A1.
Weitere Windkraftanlagen sind aus der DE 2905569 A1, der WO 2012023202 A1 , der DE 102008044807 A1 sowie der US 2006275105 A1 bekannt geworden. Further wind turbines have become known from DE 2905569 A1, WO 2012023202 A1, DE 102008044807 A1 and US 2006275105 A1.
Es ist eine Aufgabe der Erfindung, den Wirkungsgrad einer Windkraftanlage zu verbessern. It is an object of the invention to improve the efficiency of a wind turbine.
Diese Aufgabe wird mit einer Windkraftanlage erfindungsgemäß dadurch gelöst, dass entlang einer 3-Fußmastes, der auf einem Fundament aus einer im Boden verankerten Kreisringschiene mit einem drehbaren Grundrahmen steht, seitlich mehrere Stützträger angeordnet sind, wobei an jedem ein Generator vorgesehen ist, der mit einer vorgegebenen Anzahl von Rotoren gekoppelt ist, die durch eine Abschlussscheibe bestehend aus mehreren Segmenten verstärkt sind, wobei der 3-Fußmast als oberen Abschluss einen mit vier Seilen als Sturmsicherung abgespannten Kreuzträger aufweist, der die gesamte Anlage mit vier Seilen überspannt und im Mastzentrum drehend gelagert ist, wobei der 3-Fußmast frei drehbar ist. Durch die neue Bauart des Zentralmastes, der sich nach der Windrichtung, sowie mit dem Zusammenschluss der Rotoren (bevorzugt je vier übereinander mit jeweils einem Generator in der Mitte) konnte der Wirkungsgrad beträchtlich erhöht werden. Die unterschiedlichen Windstärken, die durch die verschiedenen Höhenlagen entstehen, werden dadurch optimal genutzt und der Savoniusrotor ist den Windrädern ebenbürtig. Die Höhenauswertung des Windes ist aus der beiliegenden Grafik ersichtlich. Da die Rotorpakete unterschiedliche Drehzahlen aufweisen, wird die Windeinwirkung besser verwertet. Die Anlage kann je nach Bedarf in beliebiger Höhe gebaut werden. This object is achieved with a wind turbine according to the invention that along a 3-foot mast, which stands on a foundation of an anchored in the ground circular track rail with a rotatable base frame, laterally more support beams are arranged, wherein at each a generator is provided with a predetermined number of rotors is coupled, which are reinforced by a cover plate consisting of several segments, the 3-foot mast has as upper end a tensioned with four ropes as a storm protection crossbeam, which spans the entire system with four cables and is rotatably mounted in the mast center , where the 3-foot mast is freely rotatable. Due to the new design of the central mast, which is based on the wind direction, as well as with the merger of the rotors (preferably four on top of each other, each with a generator in the middle), the efficiency could be increased considerably. The different wind strengths created by the different altitudes are thus used optimally and the Savonius rotor is equal to the wind turbines. The height evaluation of the wind can be seen in the enclosed graphic. Since the rotor packages have different speeds, the wind effect is better utilized. The system can be built at any height as needed.
Gemäß einer vorteilhaften Variante der Erfindung kann der 3-Fußmast aus drei miteinander verspreizten Stehern bestehen, wobei sich an zwei Stehern seitliche Stützträger für die Rotoren befinden und der dritte Steher nur eine Stützfunktion hat. According to an advantageous variant of the invention, the 3-foot mast can consist of three stanchions which are spread apart with one another, wherein lateral support beams for the rotors are located on two uprights and the third upright has only one support function.
Bei einer Weiterbildung der Erfindung kann es vorgesehen sein, dass jeweils zwei Rotoren oberhalb und zwei Rotoren unterhalb eines Generators gelagert sind und ein Rotorpaket bilden. In a further development of the invention, it may be provided that two rotors are mounted above and two rotors below a generator and form a rotor core.
Eine vorteilhafte Ausführungsform besteht darin, dass die Rotoren durch eine Abschlussscheibe, die in mehrere Segmente geteilt ist, gesichert sind, wobei diese Segmente mit radial verlaufenden Versteifungsrippen und mit einer rundum verlaufenden Querrippe ausgestattet sind. An advantageous embodiment is that the rotors are secured by a cover plate which is divided into a plurality of segments, wherein these segments are provided with radially extending stiffening ribs and with an all-round transverse rib.
Bei einer weiteren Variante der Erfindung ist es vorgesehen, dass die Steher des 3- Fußmastes im Grundriss ein Dreieck bilden, wobei eine Spitze des Dreiecks zwischen den Rotorpaketen hervorragt, und die Rotoren von der Spitze des Dreiecks aus betrachtet hinter dem Mittelpunkt des Kreuzträgers angeordnet und flächig verkleidet sind, wobei bei einem Einströmen des Windes der Mast auf dem Grundrahmen in die optimale Richtung gedreht wird. Die Erfindung wird im Folgenden anhand einiger Ausführungsbeispiele, welche in den Zeichnungen dargestellt sind, näher erläutert. In diesen zeigen: In a further variant of the invention, it is provided that the uprights of the 3-foot mast in plan form a triangle, wherein a tip of the triangle protrudes between the rotor packages, and the rotors arranged from the top of the triangle, viewed behind the center of the crossbeam and are surface-disguised, which is rotated at an influx of wind, the mast on the base frame in the optimum direction. The invention will be explained in more detail below with reference to some embodiments, which are illustrated in the drawings. In these show:

Fig. 1 zeigt den Querschnitt der kompletten Anlage. Die Windkraftanlage nach Fig. 1 ist dadurch gekennzeichnet, dass der Zentralmast 2 aus drei miteinander verspreizten Stehern 7a besteht. An zwei Stehern 7a sind seitliche Stützträger 16 montiert, wobei der dritte Steher 7a nur eine Stützfunktion hat. An den seitlichen Stützträgern 16 sind Generatoren 3 für jeweils zwei oberhalb und zwei unterhalb einzeln angelagerte Rotoren 4 befestigt, die sich ebenso an je einem Stützträger befinden. Je nach Höhe können die Rotorpakete in beliebiger Anzahl angeordnet werden. Fig. 1 shows the cross section of the entire system. The wind power plant according to FIG. 1 is characterized in that the central mast 2 consists of three stanchions 7a which are spread apart with one another. On two uprights 7a lateral support beams 16 are mounted, the third post 7a has only a support function. On the lateral support beams 16 generators 3 are mounted for each two above and two below individually mounted rotors 4, which are also located on a respective support beam. Depending on the height, the rotor packages can be arranged in any number.
Der Zentralmast 2 befindet sich auf einem Grundrahmen 8 und ist auf Rollen drehbar. Er schließt am oberen Ende mit einem Kreuzträger 1 ab, der in Fig. 3 in Draufsicht ersichtlich ist. Die Sturmabspannung 5 des Kreuzträgers 1 stabilisiert die gesamte Anlage. Fig. 2 zeigt eine Draufsicht auf das Fundament bestehend aus Kreisring 13 und Grundrahmen 8. Die Stützträger 16 sind seitlich so angeordnet, dass die Rotoren 4 wesentlich hinter dem Mittel 9 sind, wodurch sich das Windleitsystem 10 verbessert, indem es durch die Außenverkleidung verlängert wird. The central mast 2 is located on a base frame 8 and is rotatable on rollers. He concludes at the top with a cross beam 1, which is visible in Fig. 3 in plan view. The Sturmabspannung 5 of the crossbeam 1 stabilized the entire system. Fig. 2 shows a plan view of the foundation consisting of annulus 13 and base frame 8. The support beams 16 are laterally arranged so that the rotors 4 are substantially behind the means 9, whereby the wind guiding system 10 improves by being extended by the outer lining ,
Im Rotor 4 drückt der Wind auf eine der beiden Leitschaufeln 11 und bei Durchströmen in Folge auf die zweite Leitschaufel 1 und bewirkt den Magnus-Effekt. In the rotor 4, the wind presses on one of the two guide vanes 11 and when flowing through in succession to the second guide blade 1 and causes the Magnus effect.
Fig. 2a ist weiters eine Draufsicht in etwa 20 m Höhe mit den ersten untersten Rotoren. Fig. 2a is further a plan view in about 20 m height with the first lowermost rotors.
In Fig. 3 wird der Kreuzträger 1 in Draufsicht mit dem Windleitsystem 10 und den Rotoren dargestellt. Er ist im Zentrum auf einer Welle 26 gelagert und ermöglicht die Drehung der Mastkonstruktion 2. Die Ausladung es Kreuzträgers richtet sich nach der Größe der Rotoren 4, damit diese durch die Windabspannung 5 nicht behindert werden. In Fig. 3, the cross beam 1 is shown in plan view with the Windleitsystem 10 and the rotors. It is mounted in the center on a shaft 26 and allows the rotation of the mast construction 2. The projection of the crossbeam depends on the size of the rotors 4, so that they are not hindered by the wind bracing 5.
Fig. 4 zeigt eine Draufsicht auf die Leitschaufeln mit den Stelleinrichtungen. Die Steuerung der Rotoren 4 erfolgt elektromechanisch durch die beweglichen Teile 11a der Leitschaufeln, wie es in Fig. 5 dargestellt ist. Die Leitschaufeln 11 sind mit einer Versteifung 20 ausgestattet, auf welcher die Stelleinrichtung gelagert ist. Fig. 4 shows a plan view of the vanes with the actuators. The control of the rotors 4 is carried out electromechanically by the movable parts 11a of the vanes, as shown in Fig. 5. The vanes 11 are equipped with a stiffener 20 on which the adjusting device is mounted.
In Fig. 5 ist der Rotor 4 mit vertikaler Achse 19 und den beiden Leitschaufeln im Schrägriss dargestellt. Eine Leitschaufel 11 ist ein in der Länge nach halbiertes Rohr, welches sich zu einem Drittel ihres Durchmessers in der Mitte mit dem Drittel der zweiten Leitschaufel 11 überlappt. Durch die Teilung der Leitschaufeln 11 in einen beweglichen Teil 11a und einen unbeweglichen Teil 11b kann der Rotor 4 elektromechanisch gesteuert werden. Der bewegliche Teil 11a einer Schaufel klappt sich über den unbeweglichen Teil 11b der anderen Leitschaufel 11 und schließt die Windzufuhr ab. In Fig. 5, the rotor 4 is shown with a vertical axis 19 and the two vanes in oblique. A vane 11 is a longitudinally halved tube which overlaps one third of its diameter in the middle with the third of the second vane 11. By the division of the guide vanes 11 in a movable part 11 a and a stationary part 11 b, the rotor 4 can be controlled electromechanically. The movable part 11a of one blade folds over the immovable part 11b of the other vane 11 and closes off the wind supply.
Fig. 6 ist eine Draufsicht auf die Rotorabschlussscheibe 12, die aus mehreren Segmenten 29 besteht. Sie sind der Länge nach abgekantet und dadurch bildet sich eine Versteifungs- rippe 31. Zusätzlich verbindet eine Querrippe 30 alle Segmente 29, wodruch ein Schwingen verhindert wird. FIG. 6 is a plan view of the rotor shroud 12 consisting of a plurality of segments 29. They are folded lengthwise and this creates a stiffening In addition, a transverse rib 30 connects all the segments 29, thus preventing oscillation.
