Description

Kurzfassungshort version

Die Aufgabe dieser Windkraftanlage besteht darin elektrische Energie aus der natürlichen Ressource Wind zu gewinnen und dabei die Standorte auf hohen Häusern, Aussichtstürmen und auf freistehenden Wohnhäusern auszunutzen. Die Konstruktion der neuen Windkraftanlage ist derart angelegt, dass die in Serie kostengünstig zu produzieren ist, und sich damit ihre Investition in relativ kurzer Zeit amortisieren lässt. Die neue Windkraftanlage erfüllt damit die Aufgabe in windreichen Abschnitten elektrische Energie zu gewinnen, die bisherigen Energieträger zu entlasten und somit die Umwelt zu schonen.The task of this wind turbine is to generate electrical energy from the natural resource of wind and exploit the locations on high houses, lookout towers and on freestanding houses. The design of the new wind turbine is designed in such a way that it can be mass-produced cost-effectively, and thus its investment can be amortized in a relatively short time. The new wind turbine thus fulfills the task of generating electrical energy in windy sections, relieving the energy sources used to date and thus protecting the environment.

Diese Aufgabe wird technisch durch ein Rohr in Leichtbauweise gelöst, durch das der Wind strömt und dabei zwei hintereinander, spiegelbildliche Rotoren mit mehreren Flügeln antreibt, die schraubenförmig gebogen sind. Dadurch drehen sich die Rotoren gegensinnig um eine gemeinsame Achse und treiben Dynamos zur Erzeugung von Gleichstrom an. Der vom Wind zuerst bediente Rotor ist in der Lage einen Teil der Windenergie abzuschöpfen. Der anschließende Rotor, der so gestaltet ist, dass seine Flügel gegenläufig zu den Flügeln des ersten Rotors drehen, kann weitere Anteile der Windenergie ausnutzen. Außerdem ist durch diese Bauform die neue Windkraftanlage „Spiegelturbine” in der Lage von ihren beiden Rohrenden den Wind empfangen zu können. Die Rohr-Innenachse der Windkraftanlage ist einstellbar durch Zugelemente an beiden Rohrenden befestigt, die durch schmale Bauform den Eintritt des Windes in das Rohr kaum merklich behindern. Das Rohr selbst ist durch zwei senkrecht zum jeweiligen Wind aufeinander stehende Achsen, vertikal und horizontal, ortsfest gelagert und kann sich damit selbständig auf die unterschiedlichen Richtungen des Windes leichtgängig einstellen.This object is achieved technically by a tube in lightweight construction, through which the wind flows, thereby driving two successive, mirror-image rotors with a plurality of wings, which are helically bent. As a result, the rotors rotate in opposite directions about a common axis and drive dynamos to generate direct current. The rotor, which is first operated by the wind, is able to absorb some of the wind energy. The subsequent rotor, which is designed so that its wings rotate in opposite directions to the blades of the first rotor, can exploit further shares of wind energy. In addition, the new wind turbine "Spiegelturbine" is able to receive the wind from its two pipe ends by this design. The tube inner axis of the wind turbine is adjustable by pulling elements attached to both ends of the pipe, which obstruct the entry of the wind into the pipe barely noticeable by narrow design. The tube itself is supported by two perpendicular to the respective wind axes, vertical and horizontal, stationary and can thus set independently on the different directions of the wind smoothly.

Angewendet werden soll diese Windkraftanlage vorzugsweise auf den Dächern von hohen Häusern und freistehenden Gebäuden und auf Türmen. Eingesetzt wird sie überall dort werden, wo mit zwei- bis dreitausend Stunden im Jahr die Kraft des Windes einen deutlichen Beitrag zur Gewinnung von Energie zu liefern in der Lage ist.This wind turbine should preferably be used on the roofs of tall houses and freestanding buildings and on towers. It will be used everywhere where the power of the wind is able to make a significant contribution to the production of energy at two to three thousand hours per year.

Anhand von 1, 2, 3 und 4 wird die Erfindung der Windkraftanlage „Spiegelturbine” beschrieben.Based on 1 . 2 . 3 and 4 the invention of the wind turbine "mirror turbine" is described.

1 ist eine Perspektive der kompletten Anlage mit Blick von schräg unten und 2 und 3 sind die dazu gehörenden Schnittzeichnungen. 4 zeigt eine Perspektive der beiden Flügelsätze. 1 is a perspective of the entire complex with a view from below and diagonally 2 and 3 are the corresponding sectional drawings. 4 shows a perspective of the two sets of wings.

Im Rohr (1) drehen sich zwei Rotoren gegenläufig auf der gemeinsamen Rohr-Innenachse (5). Sie bestehen aus den Rotorwellen (2a) und (2b) und den von der Kraft des Windes angetriebenen Flügeln (3a) und (3b). Auf jeder Rotorwelle befinden sich zwei oder mehr Flügel. Stege (6) tragen die Rohr-Innenachse (2). Die Windfahnen (8) richten das Rohr (1) ständig in Windrichtung aus. Dazu ist das Rohr (1) in zwei senkrecht aufeinander stehenden Achsen, die vertikale Achse (9) und die horizontale Achse (12), leichtgängig gelagert.In the tube ( 1 ), two rotors rotate in opposite directions on the common tube inner axis ( 5 ). They consist of the rotor shafts ( 2a ) and ( 2 B ) and the blades driven by the force of the wind ( 3a ) and ( 3b ). Each rotor shaft has two or more blades. Footbridges ( 6 ) carry the inner pipe axis ( 2 ). The wind banners ( 8th ) align the pipe ( 1 ) constantly downwind. This is the pipe ( 1 ) in two mutually perpendicular axes, the vertical axis ( 9 ) and the horizontal axis ( 12 ), easily stored.

In der 2 mit dem Blick in die Windeintrittsöffnung der Spiegelturbine sind vier Flügel (3a) und (3b) mit schraubenförmigem Querschnitt im Schnitt A-A offenbart. Dadurch steht die volle Rohrinnenfläche für die Nutzung der Windenergie zur Verfügung. Die Dynamos (4a) und (4b) sind achsgleich verbunden mit den Rotoren und erzeugen die gewünschte elektrische Energie, bestehend aus Gleichstrom und Spannung. Damit können Akkus aufgeladen werden. Oder es werden Umrichter bedient, hier nicht dargestellt, die den Gleichstrom in 230 Volt Wechselstrom wandeln und danach in das örtliche Stromnetz einspeisen.In the 2 with the view into the wind inlet opening of the mirror turbine are four wings ( 3a ) and ( 3b ) with helical cross-section in section AA disclosed. As a result, the full interior pipe surface is available for the use of wind energy. The Dynamos ( 4a ) and ( 4b ) are coaxially connected to the rotors and generate the desired electrical energy, consisting of DC and voltage. This can be used to charge batteries. Or inverters are operated, not shown here, which convert the direct current into 230 volts alternating current and then feed it into the local power grid.

Die gemeinsame Rohr-Innenachse (5) der Rotoren und Dynamos ist durch radial angeordnete Zugelemente (6), wie Stege, Stangen oder Seile am Rohr (1) einstellbar befestigt. Die auftretende Biegung aus dem Winddruck wird vorzugsweise, wie in der Darstellung gezeigt, über das hochkantige Profil des Steges (6) aufgefangen.The common tube inner axis ( 5 ) of the rotors and dynamos is by radially arranged tension elements ( 6 ), such as webs, rods or ropes on the pipe ( 1 ) adjustable attached. The occurring bending from the wind pressure is preferably, as shown in the illustration, on the edgewise profile of the web ( 6 ).

Damit die Ausrichtung der Windkraftanlage nach der jeweiligen Windrichtung stetig erfolgen kann, ist der Außenmantel des Rohres (1) in zwei senkrecht aufeinander stehende Achsen (9) und (12) gelagert. Die vertikale Achse (9) besteht aus einer Rohrlagerung und aus einem inneren Bolzen, der fest mit der Grundplatte (10) der Windkraftanlage befestigt ist. Die Grundplatte (9a) wird über die Anker (11) fest mit der Turmspitze, bzw. mit dem Hausdach verbunden. Die beidseitig des Rohres (1) angeordnete horizontale Achse (10) ist über den Tragebügel (13) mit der vertikalen Achse (9) verbunden.So that the orientation of the wind turbine can take place continuously according to the respective wind direction, the outer casing of the pipe ( 1 ) in two mutually perpendicular axes ( 9 ) and ( 12 ) stored. The vertical axis ( 9 ) consists of a pipe support and an inner bolt fixed to the base plate ( 10 ) of the wind turbine is attached. The base plate ( 9a ) is placed over the anchors ( 11 ) firmly connected to the spire, or to the house roof. The two-sided of the pipe ( 1 ) arranged horizontal axis ( 10 ) is over the carrying handle ( 13 ) with the vertical axis ( 9 ) connected.

In 3 ist der Schnitt A-A aus 2, jedoch hier um 90° gedreht, gezeigt. Die genaue Positionierung der Rohr-Innenachse (5) wird mit den Einstellschrauben (7) am Außenmantel des Rohres (1) sehr einfach erreicht. Die Windfahnen (8), bestehend aus Leichtbauprofil wie die Stege (6), sind mit Schrauben (14) am Außenmantel des Rohres (1) befestigt und sorgen für die Ausrichtung der Windkraftanlage in Strömungsrichtung des Windes. Da die Windkraftanlage somit von beiden Öffnungen des Rohres vom Wind beaufschlagt werden kann, können sich die horizontalen Einstellbewegungen der Windkraftanlage auf 90 Grad beschränken.In 3 is the section AA off 2 , but here rotated by 90 °, shown. The exact positioning of the tube inner axis ( 5 ) is adjusted with the adjusting screws ( 7 ) on the outer jacket of the tube ( 1 ) achieved very easily. The wind banners ( 8th ), consisting of lightweight profile like the webs ( 6 ), are with screws ( 14 ) on the outer jacket of the tube ( 1 ) and ensure the alignment of the wind turbine in the direction of flow of the wind. Since the wind turbine can thus be acted upon by both windings of the pipe, the horizontal adjustment movements of the wind turbine can be limited to 90 degrees.
