AT 413 742 BAT 413 742 B

Die vorliegende Erfindung betrifft ein Schwungrad für Windkraftwerke, welches mit einer Flüssigkeit gefüllt ist, die aufgrund der Fliehkraft vom Zentrum zum Umfang des Schwungrades strömen kann, wobei das Schwungrad die Form eines flachen Tellers mit einer Vertiefung im Zentrum und einem nach oben umgebogenen Rand am Umfang hat. 5The present invention relates to a flywheel for wind power plants, which is filled with a liquid which can flow due to the centrifugal force from the center to the periphery of the flywheel, wherein the flywheel in the form of a flat plate having a recess in the center and an upwardly bent edge on the periphery Has. 5

Derartige Schwungräder sind z.B. aus der JP 61-149647 A oder der JP 59-1838 A bekannt. Im Ruhezustand befindet sich die Flüssigkeit im Zentrum des Schwungrades. Die Rotationsträgheitsmasse des Schwungrades ist dadurch gering und es setzt dem Anlaufen des Rotors wenig Trägheit entgegen. Im Betrieb strömt die Flüssigkeit aufgrund der Fliehkraft zum Umfang des io Schwungrades, was die Rotationsträgheitsmasse erhöht. Das Schwungrad kann dadurch mehr Rotationsenergie speichern und Schwankungen der Umdrehungen des Rotors besser ausglei-chen.Such flywheels are e.g. from JP 61-149647 A or JP 59-1838 A known. At rest, the fluid is in the center of the flywheel. The rotational inertial mass of the flywheel is thereby low and it opposes the start of the rotor little inertia. In operation, the liquid flows due to the centrifugal force to the periphery of the flywheel io, which increases the rotational inertial mass. The flywheel can thereby store more rotational energy and compensate for fluctuations in the revolutions of the rotor better.

Die bekannten Schwungradkonstruktionen verfügen über einen zentralen Behälter für die Flüs-15 sigkeit, von dem Hohlspeichen zu einem umlaufenden Hohlring ausgehen. Diese Konstruktion ist einerseits aufwendig und erfordert anderseits eine ständige Kontrolle des Füllstandes und ein Nachfüllen der Flüssigkeit, um die Schwungradwirkung im Dauerbetrieb zu gewährleisten.The known flywheel designs have a central container for the liquid from which hollow spokes emanate into a circumferential hollow ring. This construction is on the one hand consuming and on the other hand requires constant control of the level and a refilling of the liquid to ensure the flywheel effect in continuous operation.

Die Erfindung setzt sich zum Ziel, ein Schwungrad der genannten Art zu schaffen, welches 20 besonders einfach aufgebaut ist und einen wartungsfreien Dauereinsatz ermöglicht.The invention has for its object to provide a flywheel of the type mentioned, which is particularly simple in construction and allows a maintenance-free continuous use.

Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß das Schwungrad zumindest teilweise an seiner Oberseite gegenüber dem Freien zum Auffangen von Regenwasser freiliegt. 25 Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß das Schwungrad die Form eines flachen Tellers mit einer Vertiefung im Zentrum und einem nach oben umgebogenen Rand am Umfang hat und zumindest teilweise an seiner Oberseite freiliegt.This object is inventively achieved in that the flywheel is at least partially exposed at its top to the outside to collect rainwater. This object is inventively achieved in that the flywheel has the shape of a flat plate with a recess in the center and an upwardly bent edge on the periphery and at least partially exposed on its upper side.

Die Erfindung beruht auf dem Konzept einer selbsttätigen Nachfüllung und Füllstandsregulie-30 rung des Schwungrades mittels Regenwassers, das von seiner freiliegenden tellerförmigen Oberseite aufgefangen und in der Vertiefung gesammelt wird. Überschüssiges Regenwasser strömt bei der Drehung über die Oberkante des Randes ab und fehlendes Wasser wird durch aufgefangenes Regenwasser ersetzt. Das Schwungrad ist damit für einen Einsatz in Windkraftwerken, welche den Naturelementen ausgesetzt sind, besonders geeignet. 35The invention is based on the concept of automatic refilling and Füllstandsregulie-tion tion of the flywheel by means of rainwater, which is collected from its exposed plate-shaped top and collected in the recess. Excess rainwater will flow over the top of the rim as it rotates and any missing water will be replaced by trapped rainwater. The flywheel is thus particularly suitable for use in wind power plants, which are exposed to the natural elements. 35

Eine bevorzugte Ausführungsform der Erfindung zeichnet sich dadurch aus, daß die Vertiefung muldenförmig mit schräg abfallenden Flanken ist. Die Flanken verhindern Frostschäden durch gefrierendes Wasser im Winter, da sie ein Hochgleiten der Eisschicht ermöglichen. 40 Zu demselben Zweck ist es besonders vorteilhaft, wenn der Rand an seiner Innenseite mit einem elastischen Element versehen ist, bevorzugt einem luftgefüllten Schlauch, um Frostschäden im Dreh betrieb zu verhindern.A preferred embodiment of the invention is characterized in that the depression is trough-shaped with sloping flanks. The flanks prevent frost damage due to freezing water in winter, as they allow the ice to slide up. For the same purpose, it is particularly advantageous if the edge is provided on its inner side with an elastic element, preferably an air-filled hose to prevent frost damage during rotation operation.

Bevorzugt weist die Vertiefung eine verschließbare Ablaßöffnung auf, um eine Entleerung des 45 Schwungrades zu Reparatur- und Reinigungszwecken zu ermöglichen.Preferably, the recess has a closable drain opening to allow emptying of the flywheel for repair and cleaning purposes.

Eine weitere vorteilhafte Ausführungsform des Schwungrades, die für ein Windkraftwerk mit einem Rotor mit vertikaler Welle bestimmt ist, zeichnet sich dadurch aus, daß das Schwungrad auf der Welle des Rotors sitzt, bevorzugt unterhalb des Rotors. Auf diese Weise kann eine so einfache, kompakte Einheit aus Rotor und Schwungrad geschaffen werden; der Rotor wird hierbei entweder tangential oder über eine entsprechende Windhutze axial angeströmt.A further advantageous embodiment of the flywheel, which is intended for a wind power plant with a rotor with a vertical shaft, is characterized in that the flywheel sits on the shaft of the rotor, preferably below the rotor. In this way, such a simple, compact unit of rotor and flywheel can be created; The rotor is thereby either flowed axially or tangentially via a corresponding wind hood.

Die Erfindung wird nachstehend anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert. In den Zeichnungen zeigt 55The invention will be explained in more detail with reference to an embodiment shown in the drawings. In the drawings, 55

Claims (5)

3 AT 413 742 B Fig. 1 ein Windkraftwerk mit einem Rotor und einem Schwungrad gemäß der Erfindung in einer schematischen Seitenansicht, Fig. 2 das Schwungrad des Windkraftwerkes von Fig. 1 im Axialschnitt und Fig. 3 ein Detail des Schwungrades von Fig. 2. 5 Gemäß Fig. 1 weist ein Windkraftwerk 1 einen Schaufelrotor 2 mit einer vertikalen Welle 3 auf, die einen Generator 4, 5 antreibt und am Boden 6 entsprechend drehgelagert ist. Der Generator 4, 5 umfaßt ein von der Welle 3 angetriebenes Reibrad 4, welches an seinem Umfang zahlreiche Einzelgeneratoren 5 antreibt. 10 Der Schaufelrotor 2 ist für eine radiale Durchströmung von innen nach außen ausgebildet und wird von einer Windhutze 7 gespeist, die ihrerseits auf der Welle 3 drehgelagert ist und sich mittels eines Leitwerks 8 zum Wind hin ausrichtet, so daß ihre Einlaßöffnung 9 den Wind empfängt und zum Schaufelrotor 2 hin umlenkt. 15 Der Schaufelrotor 2 ist an seiner Oberseite mit einer Abdeckschale 10 und an seiner Unterseite mit einem Schwungrad 11 versehen, welches ausführlicher in den Fig. 2 und 3 gezeigt ist. Gemäß den Fig. 2 und 3 hat das Schwungrad 11 die Form eines flachen Tellers 12 mit einer 20 Vertiefung 13 im Zentrum und einem nach oben umgebogenen Rand 14 an seinem Umfang. Die Vertiefung 13 ist muldenförmig mit schräg abfallenden Flanken und wird im Ruhezustand mit Wasser bis zu einem Niveau 15 (Fig. 1) gefüllt. Im Betrieb strömt das Wasser aufgrund der Fliehkraft radial nach außen bis in den Bereich 16 innerhalb des umgebogenen Randes 14. Sollte zuviel Wasser im Schwungrad 11 sein, fließt es über die Kante 17 des umgebogenen 25 Randes 14 radial nach außen ab, sodaß im Drehbetrieb ein „Wasserring“ im Bereich 16 des umgebogenen Randes 14 vorliegt, der die Rotationsträgheitsmasse des Schwungrades 11 erhöht. Der Rand 14 ist an seiner Innenseite mit einem elastischen Element 18 versehen, bevorzugt 30 einem luftgefüllten Schlauch. Die Oberseite des Tellers 12 liegt zumindest teilweise frei, u.zw. im gezeigten Beispiel in einem Bereich 19, welcher nicht von der Windhutze 7 überdeckt ist; zu diesem Zweck ist die obere Abdeckschale 10 über dem Bereich 19 durchbrochen. Dadurch wird Regenwasser von der 35 Oberseite des Tellers 11 aufgefangen, um der Verdunstung des Wassers entgegenzuwirken bzw. diese zu kompensieren. Es versteht sich, daß bei anders gestalteten Windkraftwerken mit anders angeordneten Rotoren auch größere Teile der Oberseite des Schwungrades 11 gegenüber dem Freien und der Witterung freiliegen können, um größere Mengen Regenwasser aufzufangen. 40 Die Vertiefung 13 kann an ihrer untersten Stelle eine verschließbare Ablaßöffnung 20 aufweisen, um das Wasser zu Reinigungs- und Wartungszwecken ablassen zu können. Ferner kann eine verschließbare Füllöffnung 21 oberhalb der Vertiefung 13 vorgesehen werden, um beispielsweise eine Erstfüllung des Schwungrades 11 oder Nachfüllungen, falls der Niederschlag 45 nicht ausreicht, durchführen zu können. Die Erfindung ist nicht auf die dargestellte Ausführungsform beschränkt, sondern umfaßt alle Varianten und Modifikationen, die in den Rahmen der angeschlossenen Ansprüche fallen. 50 Patentansprüche: 1. Schwungrad für Windkraftwerke, welches mit einer Flüssigkeit gefüllt ist, die aufgrund der Fliehkraft vom Zentrum zum Umfang des Schwungrades strömen kann, wobei das 55 Schwungrad die Form eines flachen Tellers mit einer Vertiefung im Zentrum und einem 4 AT 413 742 B nach oben umgebogenen Rand am Umfang hat, dadurch gekennzeichnet, daß das Schwungrad (11) zumindest teilweise (19) an seiner Oberseite gegenüber dem Freien zum Auffangen von Regenwasser freiliegt.3 AT 413 742 B FIG. 1 shows a wind power plant with a rotor and a flywheel according to the invention in a schematic side view, FIG. 2 shows the flywheel of the wind power plant of FIG. 1 in axial section and FIG. 3 shows a detail of the flywheel of FIG. 2. According to FIG. 1, a wind power station 1 has a blade rotor 2 with a vertical shaft 3, which drives a generator 4, 5 and is correspondingly rotatably mounted on the base 6. The generator 4, 5 comprises a driven by the shaft 3 friction wheel 4, which drives numerous individual generators 5 at its periphery. 10 The blade rotor 2 is formed for a radial flow from the inside to the outside and is fed by a cowl 7, which in turn is rotatably mounted on the shaft 3 and is aligned by means of a tail 8 to the wind, so that its inlet port 9 receives the wind and deflects towards the blade rotor 2 out. The blade rotor 2 is provided on its upper side with a cover shell 10 and on its underside with a flywheel 11, which is shown in more detail in Figs. 2 and 3. 2 and 3, the flywheel 11 has the shape of a flat plate 12 with a recess 20 in the center and an upwardly bent edge 14 at its periphery. The recess 13 is trough-shaped with sloping flanks and is filled at rest with water up to a level 15 (FIG. 1). In operation, the water flows due to centrifugal radially outward into the region 16 within the bent edge 14. Should be too much water in the flywheel 11, it flows over the edge 17 of the bent edge 25 radially outward, so that in the rotary operation "Water ring" in the region 16 of the bent edge 14 is present, which increases the rotational inertial mass of the flywheel 11. The edge 14 is provided on its inside with an elastic element 18, preferably an air-filled hose. The top of the plate 12 is at least partially exposed, u.zw. in the example shown in a region 19 which is not covered by the wind hood 7; For this purpose, the upper cover shell 10 is broken over the area 19. As a result, rainwater from the top of the plate 11 is collected to counteract or compensate for the evaporation of the water. It is understood that in differently designed wind turbines with differently arranged rotors and larger parts of the top of the flywheel 11 can be exposed to the outside and the weather to collect larger amounts of rainwater. 40 The recess 13 may have at its lowest point a closable drain opening 20 to drain the water for cleaning and maintenance can. Furthermore, a closable filling opening 21 can be provided above the depression 13 in order, for example, to be able to carry out initial filling of the flywheel 11 or refills if the precipitate 45 is insufficient. The invention is not limited to the illustrated embodiment, but includes all variants and modifications that fall within the scope of the appended claims. A flywheel for wind power plants, which is filled with a liquid which can flow from the center to the periphery of the flywheel due to the centrifugal force, the flywheel in the form of a flat plate with a recess in the center and a 4 AT 413 742 B has upwardly bent edge on the periphery, characterized in that the flywheel (11) at least partially (19) on its upper side exposed to the outside for collecting rainwater. 2.
