Abstract

The rotor has three vertical rotor blades arranged on a base circle for forming extensions of three sides of equilateral triangles. The triangles are extended from a center of each side. The rotor has a flat, curved or an aerodynamic profile. A rotor axis runs perpendicular through the rotor and a generator housing. The rotor transfers power to a generator, which is provided below the rotor. The generator and components of the rotor are provided at a ground level on a base. A gap is formed in center of the rotor. The rotor is made of a plastic material.

Description

Windkraftanlagen werden dazu genutzt Windenergie in elektrische Energie umzuwandeln. Es gibt zwei Arten von Windkraftanlagen, zum einen die so genannten Auftriebsläufer und zum anderen die Widerstandläufer. Auftriebsläufer werden wegen ihres besseren Wirkungsgrades für die Stromproduktion eingesetzt. Diese müssen jedoch um mehr Leistung zu erbringen immer größer und höher gebaut werden. Widerstandsläufer wie der Savonius Rotor und der Darrieus Rotor sind wegen ihres geringeren Wirkungsgrades nicht so weit verbreitet. Aber genau genommen kommt es nicht auf den Wirkungsgrad oder die maximale Leistung an, sondern darauf das jede KW/h die mit Hilfe von Windkraft erzeugt wurde nicht mehr in herkömmlichen Kraftwerken erzeugt werden muss.Wind turbines are used to convert wind energy into electrical energy. There are two types of wind turbines, the so-called buoyancy runner and on the other hand, the resistance runners. buoyancy runner are used because of their better efficiency for electricity production. These have to However, in order to perform better, it will be built bigger and bigger. Resistance runner like the Savonius rotor and the Darrieus rotor are due to their smaller size Efficiency not so widespread. But actually comes It does not depend on the efficiency or the maximum power, but on that each KW / h which was not generated with the help of wind power more in conventional Power plants must be generated.

Dieser Rotor dient einer verbesserten Ausnutzung der gesamten Bandbreite der Windgeschwindigkeiten. Vereinfacht den Bau, Transport, Aufbau und die Wartung einer solchen Anlage. Darüber hinaus verringert der Rotor die Gefahr für Vögel, minimiert die Lärmbelastung und reduziert den Schattenwurf (Diskoeffekt). Außerdem benötigt dieser Typ von Rotor wesentlich weniger Platz als eine herkömmliche Anlage.This Rotor serves for improved utilization of the entire bandwidth the wind speeds. Simplifies the construction, transport, construction and the maintenance of such a facility. In addition, the rotor decreases the danger for birds, minimizes the noise pollution and reduces the shadows (disco effect). In addition, this type of rotor is essential less space than a conventional one Investment.

Dies ergibt sich durch die Senkrechte Anordnung der Rotorblätter und die spezielle Ausrichtung der Rotorblätter auf dem Grundkreis.This results from the vertical arrangement of the rotor blades and the special orientation of the rotor blades on the base circle.

Dadurch dass dieser Rotor schon bei niedrigen Windgeschwindigkeiten anfängt sich zu drehen und bei Höheren Windgeschwindigkeiten sich durch den eigenen Luftwiderstand selbst Drosselt ist es möglich selbst bei niedrigen Windgeschwindigkeiten elektrische Energie zu erzeugen. Da die Einzelteile nicht unbedingt aus einem Stück sein müssen lassen sich die Bauteile einfacher transportieren. Weil der Generator hier nicht wie sonst Üblich in einer Kleinen Kanzel hoch oben auf einem Turm angebracht ist, vereinfacht sich der Aufbau und die Wartung erheblich. Diese Art von Rotor erzeugt durch die geringe Geschwindigkeit wesentlich weniger Lärm. Wegen der kompakten form ist es auch Vögeln möglich diesen Rotor als Hindernis zu und ausweichen. Die Zylindrische Form begrenzt die Größe des Schattens und verhindert einen schnellen Wechsel zwischen Licht und Schatten. Es ist aber darauf zu achten, dass die Oberfläche nicht glänzt, da sonst unangenehme Spiegelungen entstehen. Außerdem benötigt er nur so viel Platz wie der Durchmesser des Rotors groß ist, somit können auf der gleichen Fläche mehrere Anlagen installiert werden als das aktuell der Fall ist.Thereby that this rotor starts even at low wind speeds to turn and higher Wind speeds themselves through their own air resistance It is possible to throttle itself to generate electrical energy at low wind speeds. Since the items do not necessarily have to be in one piece, the components can be transport easier. Because the generator is not here as usual in A small pulpit mounted high on top of a tower simplifies the construction and the maintenance considerably. This type of rotor generates Due to the low speed much less noise. Because of In the compact form, it is also birds possible this rotor as an obstacle and evade. The cylindrical shape limits the size of the shadow and prevents a quick change between light and shadow. But it is important to ensure that the surface does not shine because otherwise unpleasant reflections arise. He also only needs as much space as the diameter of the rotor is large, thus can on the same area several systems are installed than is currently the case.

Die Konstruktion des Rotors ist denkbar einfach. Zuerst benötigt man einen Kreis. In die Mitte des Kreises kommen 4 Kleine gleichseitige Dreiecke die ein großes Dreieck bilden (1). Die Größe des großen Dreiecks in der Mitte sollte mindestens 10% und maximal 50% des Kreisdurchmessers betragen damit in der Mitte Platzt bleibt für die durchströmende Luft ist. Jetzt werden die Spitzen des Großen gleichseitigen Dreiecks mit den Spitzen des kleinen mittleren Dreiecks verbunden. Dadurch erhält man den Mittelpunkt des Dreiecks (2). Dieser Mittelpunkt muss jetzt über den Mittelpunkt des Kreises gelegt werden und erhält damit die Position der Rotorachse. Danach werden die einzelnen Seiten des großen Dreiecks ab der Hälfte weiter verlängert (3). Dadurch erhält man die Positionen der Rotorblätter und bestimmt die Drehrichtung (4). Die Rotoren können flach, gebogen oder ein aerodynamisches Profil haben. Diese Rotoren werden dann jeweils unten und oben an dem Kreis befestigt (5). Die Rotorachse verläuft senkrecht durch den gesamten Rotor und dem Generatorgehäuse. Sie ist fest am oberen und unteren Kreis montiert und überträgt die Kraft auf den Generator. Der Generator befindet sich zusammen mit den andern Bauteilen die für die Stromproduktion benötigt werden in einem separaten Gehäuse unter dem Rotor (6). Die Rotorachse verläuft durch dieses Gehäuse durch und ist an ihrem unteren Ende und am Oberen Ende des Generatorgehäuses Drehbar gelagert. Durch diese Befestigung ist es der Achse möglich horizontale Kräfte die auf den Rotor einwirken aufzunehmen und gewährleistet somit einen sicheren Stand. Das Gehäuse solle dabei aber groß genug sein um alle Kräfte die auf es einwirken aufnehmen zu können. Die Äußere Form ist dabei nicht von belang (7).The construction of the rotor is very simple. First, you need a circle. In the middle of the circle are 4 small equilateral triangles forming a large triangle ( 1 ). The size of the large triangle in the middle should be at least 10% and a maximum of 50% of the circle diameter so that there is a burst in the middle for the air flowing through. Now the tips of the big equilateral triangle are connected to the tips of the small middle triangle. This gives the center of the triangle ( 2 ). This center must now be placed over the center of the circle and thus receives the position of the rotor axis. After that, the individual sides of the big triangle are extended from half onwards ( 3 ). This gives the positions of the rotor blades and determines the direction of rotation ( 4 ). The rotors can be flat, curved or have an aerodynamic profile. These rotors are then attached to the top and bottom of the circle ( 5 ). The rotor axis runs vertically through the entire rotor and the generator housing. It is firmly mounted on the upper and lower circle and transfers the power to the generator. The generator is together with the other components needed for power production in a separate housing under the rotor ( 6 ). The rotor axis passes through this housing and is rotatably mounted at its lower end and at the upper end of the generator housing. This attachment allows the axle to absorb horizontal forces acting on the rotor, thus ensuring a secure footing. However, the housing should be large enough to absorb any forces acting on it. The external form is not of importance ( 7 ).

Als Material für die gesamte Konstruktion kommen leichte Metalle oder Kunststoffe in Frage. Möglich ist Aluminium, Kohlefaserverbundstoffe (Karbon) oder Glasfaserverstärkte Kunststoffe. Es können auch andere Materialen aus dem bereich Luft- und Raumfahrt genutzt werden. Es ist auf maximale Stabilität und geringes Gewicht wert zu legen. Das Gehäuse in dem der Generator untergebracht ist kann auch aus herkömmlichen Materialien wie Stahlbeton errichtet werden. Die Rotorachse jedoch muss sehr stabil sein, deshalb kommen hier nur hochfeste Werkstoffe in Frage wie Stahl, Aluminium oder Karbon.When Material for the entire construction come lightweight metals or plastics in question. Is possible Aluminum, carbon fiber composites (carbon) or glass fiber reinforced plastics. It can Other materials used in the aerospace industry become. It's worth it for maximum stability and light weight to lay. The housing where the generator is housed can also be made of conventional materials how to build reinforced concrete. The rotor axis, however, must be very be stable, so here only high-strength materials in question like steel, aluminum or carbon.

Die Wartung und Reparatur ist denkbar einfach, da sich der Generator und alle anderen Wichtigen Bauteile sich Ebenerdig auf dem Boden befinden. Somit können Defekte Bauteile ohne großen Aufwand ausgetauscht werden.The Maintenance and repair is extremely easy as the generator and all the other important components are ground level on the ground are located. Thus, you can Defective components without big ones Expenditure to be exchanged.

Als mögliche Standorte kommen Gebiet in frage wo die Windverhältnisse nicht gerade optimal sind. Wo Winde mit unterschiedlichen Windgeschwindigkeiten herrschen oder wo bedingt durch die Natur oder Gebäude der Wind abgelenkt oder gebremst wird. Als Standort sind auch Dächern von hohen Gebäuden möglich, vorausgesetzt dass die dafür geeignet sind.When possible Locations come into question where the wind conditions are not exactly optimal are. Where winds with different wind speeds prevail or where distracted by nature or buildings the wind or is slowed down. As a location roofs of tall buildings are possible, provided that's for that are suitable.
