Die Erfindung stellt sich daher die Aufgabe, eine Windkraftanlage der genannten Art zu schaffen, mit dem Ziel, möglichst viel Strömungsenergie in Bewegungsenergie des Rotors umzusetzen.The Invention is therefore the task of a wind turbine of the with the aim of generating as much flow energy as possible to convert into kinetic energy of the rotor.
Die Aufgabe wird gemäß einem ersten Aspekt der Erfindung gelöst durch eine Windkraftanlage mit den im Anspruch 1 aufgezeigten technischen Merkmalen, sowie gemäß einem zweiten Aspekt der Erfindung durch eine Windkraftanlage mit den im Anspruch 27 aufgezeigten technischen Merkmalen.The Task is done according to a solved first aspect of the invention by a wind turbine having the technical features indicated in claim 1, as well as according to one second aspect of the invention by a wind turbine with the characterized in claim 27 technical features.
In den Unteransprüchen sind weitere bevorzugte Ausgestaltungen der Erfindung genannt.In the dependent claims are further preferred embodiments of the invention mentioned.
Erfindungsgemäß findet in erster Linie eine ideale Aufnahme der Strömung statt und wird die Strömung genau auf der richtigen Seite der Strömung komprimiert. Durch ein gutes Zusammenwirken von Strömungsdruck und Aerodynamik mit den Leitflächen kann eine ideale Umsetzung der Strömungsenergie erfolgen. Die Anlagenstatik wird dadurch geschont, dass durch die erreichte gute Frequenzkonstanz eine ideale Gewichts- und Massenausgewogenheit stattfindet. Die Erfindung ermöglicht ferner, dass die Aerodynamik an den Rotorflügeln schnellstmöglich zu arbeiten beginnt. In der erfindungsgemäßen Ausgestaltung der Profile der Rotorflügel wird daher sowohl als bevorzugte Ausgestaltung der Anordnung der Einleitflächenkonstruktion gemäß dem ersten Aspekt der Erfindung als auch als eigenständiger zweiter Aspekt der Erfindung ein Schutz gesehen und beansprucht. Die Anlage kann, ohne Schaden zu nehmen und ohne, dass sie abgeschaltet werden muss, bis zum Orkan laufen. Die Anlage passt ferner in das Landschaftsbild und stellt sich nicht so aufdringlich dar, wie es bei den Anlagen mit Horizontalachse der Fall ist. Es können kostengünstige Materialien zum Bau der Anlage verwendet werden, um einen positiven Kosten-/Nutzeneffekt zu erzielen.According to the invention finds In the first place, an ideal intake of the flow takes place and the flow becomes accurate compressed on the right side of the flow. Through a good interaction of flow pressure and aerodynamics with the fins an ideal implementation of the flow energy can take place. The System statics is protected by the fact that achieved by the good Frequency constancy an ideal weight and mass balance takes place. The invention allows Furthermore, that the aerodynamics of the rotor blades as fast as possible work begins. In the inventive design of the profiles the rotor wing is therefore both as a preferred embodiment of the arrangement of admission surface according to the first Aspect of the invention as well as a separate second aspect of the invention a protection seen and claimed. The plant can, without damage and without having to shut it down, to the hurricane to run. The plant also fits into the landscape and provides not as intrusive as it is with the systems with horizontal axis the case is. It can inexpensive Materials used to construct the plant are used to make a positive Cost / benefit effect to achieve.
Die erfindungsgemäße Anlage kann windrichtungsunabhängig arbeiten. Sie kann ein Fundament, einen Maschinenraum, einen turmartigen Maschinenaufbau und ein Dach umfassen. Der Maschinenaufbau besteht dann vorzugsweise als Korpus aus zwei oder mehreren Grundböden, zwischen welchen sich die Einleitkonstruktionen befinden. Die Etagen werden bevorzugt durch die Grundböden gebildet, wobei sich zwischen zwei Grundböden immer eine Etage befindet. Zwei Etagen haben somit drei Grundböden. Die maximale Höhe der Anlage wird durch die zugelassene Statikberechnung bestimmt, sowie die Möglichkeiten des Anlagendurchmessers und die möglichen Rotorachslängen. Aus Statikgründen sind günstigerweise die Leitflächen in den einzelnen Etagen direkt übereinander angeordnet. Die Strömung in der Anlage wird in Richtung der Rotoren verdichtet, so dass die Strömungsgeschwindigkeit erhöht wird. Die Leitflächen sitzen bevorzugt so in der Anlage, dass „zurücklaufende Flügel" (d. h. nicht von der Windströmung in Soll-Drehrichtung angetriebene Flügel) von der Frontanströmung freigestellt werden. Der Rotor besitzt vorzugsweise drei Flügel, die nach dem Durchströmungsprinzip arbeiten. Der Maschinenraum hat bevorzugt die Grundfläche einer Bernardschen Zelle und stellt eine konisch nach oben laufende Bienenwabenform dar. Der Vorteil dieser Ausgestaltung liegt darin, dass der Wind durch diese Schräge besser in die Anlage geleitet wird. Die Anordnung der Einleitflächen ist so gestaltet, dass die Strömung immer auf die in Drehrichtung des Rotors zeigende Seite des Rotors strömt. An ihrem jeder Ecke des sechseckigen Korpusses benachbarten Ende zeigen die großen Einleitflächen bevorzugt in Richtung Rotorachse und sind am Ende in Drehrichtung des Rotors gebogen. Dazwischen sitzen vorzugsweise die 6 kleinen Einleitflächen, die bevorzugt zur in Drehrichtung nachfolgenden Korpuskante in paralleler Richtung stehen. Diese kleinen Einleitflächen entsprechen bevorzugt einem Drittel der großen Leitflächen in ihrer Aufladung.The inventive plant can be wind direction independent work. It can be a foundation, a machine room, a tower-like one Machine construction and a roof include. The machine structure exists then preferably as a body of two or more ground floors, between which are the Einleitkonstruktionen. The floors will be preferably through the ground floors formed, with there is always a floor between two ground floors. Two floors thus have three floors. The maximum height of the plant is determined by the approved static calculation, as well as the options of the plant diameter and the possible rotor axis lengths. Out static reasons are conveniently the fins in the individual floors directly above each other arranged. The flow in the plant is compressed in the direction of the rotors, so that the Flow rate is increased. The fins preferably sit in the plant so that "returning wings" (i.e., not from the wind flow in the desired direction of rotation driven blades) exempted from the front inflow become. The rotor preferably has three wings, which according to the flow principle work. The engine room preferably has the footprint of a Bernard Cell and provides a conically upwardly running honeycomb shape The advantage of this embodiment is that the wind through this slope better directed to the plant. The arrangement of the inlet surfaces is designed so that the flow always on the side facing the rotor in the direction of rotation of the rotor flows. At its end adjacent to each corner of the hexagonal carcass show the big ones admission surfaces preferably in the direction of the rotor axis and are at the end in the direction of rotation of the rotor bent. In between, there are preferably the 6 small ones admission surfaces, the preferred for in the direction of rotation subsequent body edge in parallel Direction. These small inlet surfaces are preferred a third of the big ones baffles in their charge.
Das Dach kann in der Mitte eine Erhebung aufweisen und somit vorstehen, damit die ganze Anlage abgedeckt wird. Die Flügel des Rotors können im Innenteil aus einem geraden Stück bestehen und im äußeren, der Windströmung zugewandten Teil aus einer Rundung bestehen. Das gerade Stück hat dann vorzugsweise die Länge von einem Sechstel des Durchmessers des Rotorkreises und die Rundung ist vorzugsweise genau die Krümmung von einem Achtel des Durchmessers des Rotorkreises. An der Vorderkante der Rotorflügel kann noch eine Abschrägung angebracht sein. Die großen Leitflächen haben durch die sechseckige Ausführung des Korpusses noch einen Abstand zum Rotor. Dieser Platz kann genutzt werden, um in Drehrichtung des Rotors zeigende Krümmungen einzufügen. Es lohnt sich auch, als Variante eine Druckseitentangente einzuziehen, damit der Unterdruck und der Überdruck besser hervortreten. Anstelle der Abschrägung an der Vorderkante der Flügel wäre ein Rundstab, der mit der Flügelform eingearbeitet ist, von Vorteil. Die Rotoretagenböden und die Etagenböden sitzen in der Regel auf gleicher Höhe.The Roof can have an elevation in the middle and thus protrude, so that the whole plant is covered. The wings of the rotor can in Inner part of a straight piece exist and in the outer, the wind flow facing part consist of a rounding. The straight piece has then preferably the length one-sixth of the diameter of the rotor circle and the rounding is preferably exactly the curvature of one-eighth of the diameter of the rotor circle. At the front edge the rotor wing can still be a bevel to be appropriate. The big ones Have guide surfaces through the hexagonal design of the carcase still a distance to the rotor. This place can be used be to curvatures pointing in the direction of rotation of the rotor insert. It is also worthwhile to use a pressure-side tangent as a variant, so that the negative pressure and the overpressure stand out better. Instead of the chamfer at the front edge of the wing would be a Round rod, with the wing shape incorporated, is an advantage. The rotor floors and the floors sit usually at the same height.
