ΑΤ 403 401 ΒΑΤ 403 401 Β
Die vorliegende Erfindung betrifft eine Vorrichtung zur Erzeugung von elektrischer Energie aus Windkraft, mit einem Mast, der über Fundamente im Boden verankert ist, einem Rotor, der drehbar gelagert ist, sowie mit einem bodennah angeordneten Generator zur Erzeugung von elektrischer Energie, der mit dem Rotor verbunden ist.The present invention relates to a device for generating electrical energy from wind power, with a mast which is anchored in the ground via foundations, a rotor which is rotatably mounted, and with a generator arranged close to the ground for generating electrical energy which is connected to the rotor connected is.
Es sind Windkraftanlagen bekannt, die aus einem Mast bestehen, auf dem ein drehbares Gehäuse befestigt ist, in dem ein Generator angeordnet ist. Über ein entsprechendes Getriebe oder direkt mit dem Generator verbunden ist ein Windrad mit im wesentlichen waagrechter Achse. Nachteilig bei solchen Windkraftanlagen ist der relativ hohe Geräuschpegel und die Notwendigkeit, den Generator an der Spitze des Mastes vorsehen zu müssen. Die Belastung des Mastes wird auf die Weise zusätzliche zu der aus den Windkräften entstehenden Belastung vergrößert.Wind turbines are known which consist of a mast on which a rotatable housing is fastened, in which a generator is arranged. A wind turbine with an essentially horizontal axis is connected via a corresponding gear or directly to the generator. A disadvantage of such wind turbines is the relatively high noise level and the need to have to provide the generator at the top of the mast. The load on the mast is increased in addition to the load resulting from the wind forces.
Die DE 29 32 293 A1 zeigt eine Windkraftanlage mit einem bodennah angeordneten Generator, welcher am oder im Fuß des Tragmastes angeordnet ist. Diese Anordnung hat den Nachteil, daß relativ aufwendige schalldämmende Maßnahmen erforderlich sind, um die vom Generator verursachte Lärmemission an die Umgebung zu mindern.DE 29 32 293 A1 shows a wind power plant with a generator arranged close to the ground, which is arranged on or in the foot of the mast. This arrangement has the disadvantage that relatively complex sound-absorbing measures are required in order to reduce the noise emissions to the environment caused by the generator.
Aus der DE-A 29 16 988 ist eine Windkraftanlage bekannt, bei der Schalenkreuze vorgesehen sind, die durch die Windkraft gedreht werden. Dabei ist vorgesehen, daß über eine sehr aufwendige und komplizierte Apparatur ein Schalenkreuz über ein Kardangelenk in Bezug auf eine Drehachse verschwenkt wird. Über die Ausbildung oder Anordnung eines Generators zur Erzeugung von Strom ist jedoch in diesem Stand der Technik nichts ausgesagt. Weiters betrifft die US-A 625 614 ein Windrad zum Antreiben einer Pumpe, bei dem ein Kurbeltrieb vorgesehen ist, um die Kraft auf die Pumpe zu übertragen.From DE-A 29 16 988 a wind power plant is known in which cup crosses are provided which are rotated by the wind power. It is provided that a shell cross is pivoted about a universal joint with respect to an axis of rotation via a very complex and complex apparatus. However, nothing is said in this prior art about the design or arrangement of a generator for generating electricity. Furthermore, US-A 625 614 relates to a wind turbine for driving a pump, in which a crank mechanism is provided in order to transmit the force to the pump.
Die US-A 4 115 032 betrifft ferner den Rotor eines Windrades, der kugelförmig ausgebildet ist.US-A 4 115 032 further relates to the rotor of a wind turbine which is spherical.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zur Erzeugung von elektrischer Energie aus Windkraft zu schaffen, die leise, wirtschaftlich und leicht herstellbar ist.The object of the present invention is to provide a device for generating electrical energy from wind power which is quiet, economical and easy to produce.
Erfindungsgemäß ist vorgesehen, daß der Generator im Bereich des Fundaments unter dem Bodenniveau angeordnet ist.According to the invention it is provided that the generator is arranged in the area of the foundation below the ground level.
Wesentlich an der vorliegenden Erfindung ist die Möglichkeit einer absoluten Geräuschdämmung, die durch die besondere Anordnung des Generators in leichter Weise möglich ist. Weitere besonders vorteilhafte Wirkungen der Erfindung bestehen darin, daß der Generator fast vollständig von schädlichen Umwelteinflüssen sicher ist. Es sind daher bei der Erfindung keine Probleme mit zu hohen oder zu niedrigen Temperaturen zu erwarten, die Gefahr des Blitzschlags kann minimiert werden und dgl.What is essential to the present invention is the possibility of absolute noise insulation, which is possible in a simple manner due to the special arrangement of the generator. Further particularly advantageous effects of the invention are that the generator is almost completely safe from harmful environmental influences. There are therefore no problems with too high or too low temperatures to be expected in the invention, the risk of lightning can be minimized and the like.
In einer besonders günstigen Ausführungsvariante der Erfindung ist vorgesehen, daß der Rotor eine im wesentlichen waagrechte Drehachse aufweist und daß der Generator über ein Kegelradgetriebe und eine senkrecht im Mast angeordnete Welle angetrieben wird.In a particularly favorable embodiment of the invention it is provided that the rotor has an essentially horizontal axis of rotation and that the generator is driven via a bevel gear and a shaft arranged vertically in the mast.
Am Kopf des Mastes ist dabei nur der Rotor und das Kegelradgetriebe angeordnet. Der Mast kann daher relativ leicht ausgebildet werden, so daß eine wirtschaftliche Lösung erreicht wird. In einer anderen vorteilhaften Ausführungsvariante der Erfindung ist vorgesehen, daß der Rotor eine senkrechte Achse aufweist. Dadurch kann eine besonders günstige Ausnützung der Windkraft erreicht werden.Only the rotor and the bevel gear are arranged on the head of the mast. The mast can therefore be made relatively light, so that an economical solution is achieved. Another advantageous variant of the invention provides that the rotor has a vertical axis. This enables particularly favorable utilization of wind power to be achieved.
Weiters ist es im Sinne der Erfindung möglich, daß der Rotor eine im wesentlichen senkrechte Drehachse aufweist. Auf diese Weise kann eine besonders gute Ausnützung der Windkraft erreicht werden. Bei Rotoren mit waagrechter Achse kann nämlich naturgemäß nur ein kreisförmiger Arbeitsbereich der Windkraftanlage realisiert werden. Wenn nun mehrere Anlagen nebeneinander aufgestellt werden, so ergibt sich dabei entweder eine Überlappung, die die erforderliche Anzahl der Anlagen in unwirtschaftlicher Weise vergrößert, oder es bleiben Bereiche ungenützt. Insbesonders kann der Bodenbereich nur zu einem geringen Teil ausgenützt werden. Durch die obige bevorzugte Ausführungsvariante der Erfindung kann insbesonders ein im wesentlichen rechteckiger Strömungsbereich durch die Anlage abgedeckt werden. Dies ermöglicht eine besonders günstige Ausnützung der Windkraft.Furthermore, it is possible in the sense of the invention that the rotor has an essentially vertical axis of rotation. In this way, particularly good utilization of wind power can be achieved. With rotors with a horizontal axis, of course, only a circular working area of the wind power plant can be realized. If several systems are now set up side by side, there is either an overlap that increases the required number of systems in an uneconomical manner, or areas remain unused. In particular, only a small part of the floor area can be used. The above preferred embodiment variant of the invention can in particular cover an essentially rectangular flow area through the system. This enables particularly favorable utilization of wind power.
Eine besonders einfache und kostengünstige Ausführung kann dadurch erreicht werden, daß der Mast gemeinsam mit dem Rotor drehbar ausgeführt ist. Durch die Tatsache, daß der Mast gleichzeitig die Antriebswelle darstellt, wird eine Verringerung der Anzahl der erforderlichen Bauteile erreicht.A particularly simple and inexpensive design can be achieved in that the mast is made rotatable together with the rotor. The fact that the mast is also the drive shaft reduces the number of components required.
Dabei ist es besonders günstig, wenn die Rotorblätter im wesentlichen schalenförmig ausgebildet sind. Ein besonders hoher Wirkungsgrad der erfindungsgemäßen Anlagen kann erreicht werden, wenn das Profil der schalenförmigen Rotorblätter einen konvexen Abschnitt aufweist, der beiderseits von konkaven Abschnitten umgeben ist. Durch diese Ausführung kann über einen weiten Bereich des Drehwinkels eine große Antriebskraft erzeugt werden.It is particularly advantageous if the rotor blades are essentially bowl-shaped. A particularly high efficiency of the systems according to the invention can be achieved if the profile of the cup-shaped rotor blades has a convex section which is surrounded on both sides by concave sections. With this design, a large driving force can be generated over a wide range of the rotation angle.
In einer weiteren besonders begünstigten Ausführungsvariante der Erfindung ist vorgesehen, daß die Rotorblätter entlang einer Schraubenlinie verdreht sind. Es hat sich insbesonders herausgestellt, daß das Drehmoment, das vom Wind auf den Rotor ausgeübt wird, einer Schwankung unterworfen ist, deren Frequenz bei einem dreiflügeligen Rotor der dreifachen Drehzahl des Rotors entspricht. Dies beruht auf der 2In a further particularly advantageous embodiment variant of the invention it is provided that the rotor blades are rotated along a helix. In particular, it has been found that the torque which is exerted on the rotor by the wind is subject to a fluctuation, the frequency of which in a three-bladed rotor corresponds to three times the speed of the rotor. This is based on the 2nd
