Abstract

The wind powered generator has rotor with vertical axis of rotation. The generator is designed as multipurpose arrangement in order to improve generator efficiency. The generator uses esp. a conventional Savonius rotor as wind powered rotor. The wings (12, 13) of the rotor are designed as solar energy collectors. A wing core channel (14, 15) absorbs the energy and removes it by a fluid medium. The cores are covered by transparent covers (21) which, however, prevent heat conduction. The core elements are used simultaneously as structural components accommodating loads imposed by wind and centrifugal forces.

Description

Beschreibunx Windkraftmaschine Die Erfindung bezieht sich auf eine Windkraftmaschine mit einem Windrad, dessen Drehachse senkrecht zur Erdoberfläche angeordnet ist, insbesondere mit einem Savonius-Rotor. Derartige Anordnungen sind allgemein bekannt.Description wind power machine The invention relates to a Wind power machine with a wind turbine whose axis of rotation is perpendicular to the earth's surface is arranged, in particular with a Savonius rotor. Such arrangements are well known.

Ein Nachteil von Windkraftmaschipen ist, daß bei niedrigen Windgeschwindigkeiten nur geringe Energie gewonnen werden kann.A disadvantage of wind turbines is that at low wind speeds only little energy can be obtained.

Der Etfindung liegt die Aufgabe zugrunde, die Windkraftmaschine der eingangs genannten Art so zu gestalten, daß eine wesentlich höhere Energiegewinnung möglich ist.The Etfindung is based on the task of the wind power machine To design the type mentioned in such a way that a much higher energy production is possible.

Die Lösung gelingt dadurch, daß die Windflügel als Sonnenkollektoren mit einem die Strahlungsenergie der Sonne absorbierenden Kern ausgebildet und von einem Medium durchströmt sind, welches die den Windflügeln zugeführte Wärme zur Nutzbarmachung abführt.The solution is achieved in that the wind blades act as solar collectors formed with a core absorbing the radiation energy of the sun and from a medium are flowed through, which the heat supplied to the wind blades for Utilization leads away.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous refinements of the invention are set out in the subclaims marked.

Durch die Kombination einer Windkraftmaschine mit einem Sonnenkollektor ergibt sich insbesondere der Vorteil, daß der Platzbedarf im Vergleich zur Aufstellung zweier getrennter Einzelanlagen halbiert ist. Darüber hinaus ergibt sich eine nicht nur höhere, sondern auch gleichmäßigere Energiegewinnung, da zu Zeiten niedriger Windgeschwindigkeit meistens höhere Sonnenenergie verfügbar ist und umgekehrt.By combining a wind power machine with a solar collector there is a particular advantage that the space requirement compared to the installation two separate individual systems is halved. In addition, one does not arise only higher, but also more even energy generation, since lower at times Wind speed usually higher solar energy is available and vice versa.

Wesentlich ist, daß ein Windrad verwendet ist, dessen Drehachse im wesentlichen senkrecht zur Erdoberfläche angeordnet ist, wie insbesondere bei einem Savonius-Rotor. Die Flügel eines solchen Windrades bieten der Sonnenstrahlung zu jeder Tageszeit eine große Auffangfläche, welche annähernd gleich dem Produkt aus Höhe und Durchmesser des Windrades ist.It is essential that a wind turbine is used whose axis of rotation is in is arranged substantially perpendicular to the earth's surface, as in particular with a Savonius rotor. The blades of such a wind turbine offer solar radiation a large collection area at any time of day, which is approximately equal to the product The height and diameter of the wind turbine is.

Ein weiterer Vorteil des für die erfindungsgemäße Lösung gewählten Windrades ist dessen niedrige Drehzahl (Langsamläufer), welche hinsichtlich der Bemessung auf ausreichende Festigkeit keine Schwierigkeiten bereitet. Es ist sogar möglich, die für die Sonnenkollektoren benötigten Bauteile ohne zusätzliche Versteifungsmaßnahmen als Flügel einzusetzen. Deshalb ist im Vergleich zu zwei voneinander getrennten Anlagen auch der Material-und Herstellungsaufwand geringer. Der geringe Nachteil, daß für das die rotierenden Sonnenkollektoren durchströmende Medium eine Kupplungseinrichtung benötigt wird, welche eine Zu- und Abführung des Mediums zu einem ortsfesten Anschluß ermöglicht, ist gegenüber den erzielten Vorteilen vernachlässigbar.Another advantage of the solution chosen for the solution according to the invention Wind turbine is its low speed (slow runner), which in terms of the Dimensioning for sufficient strength poses no difficulties. It is even possible, the components required for the solar collectors without additional stiffening measures to use as a wing. That is why compared to two separate from each other Plants also have lower material and manufacturing costs. The slight disadvantage that a coupling device for the medium flowing through the rotating solar collectors is required, which is a supply and discharge of the medium to a fixed connection is negligible compared to the advantages achieved.

Die Erfindung wird anhand eines in der Zeichnung dargestellten vorteilhaften usführungsbeispiels erläutert.The invention is based on an advantageous shown in the drawing execution example explained.

Fig. 1 zeigt die Seitenansicht eines erfindungsgemäß gestalteten Savonius-Rotors.Fig. 1 shows the side view of a Savonius rotor designed according to the invention.

Fig. 2 zeigt einen Querschnitt durch die Flügel des Savonius-Rotors nach Fig. 1.Fig. 2 shows a cross section through the blades of the Savonius rotor according to Fig. 1.

Die senkrechte Achse 1 des Savonius-Rotors 2 ist in Radiallagern3 4 und 5 drehbar gelagert. Die axialen Kräfte sind durch Axiallager 6 und 7 aufgefangen. Der untere Lagerbock 8 dient gleichzeitig zur Aufnahme der durch den Savonius-Rotor zu betreibenden Einrichtungen, wie elektrische Stromerzeuger, Pumpen oder dergleichen, welche beispielsweise über das Riemenrad 9 nneetrieben werden können. Die obere Lagerstütze 10 ist durch mindestens 3 Seile 11 mit dem Erdboden verspannt. Die in Form von Halbzylinderschalen ausgebildeten Flügel 12 und 13 weisen im Inneren jeweils ein mäanderförmiges Rohrsystem 14 bzw. 15 auf, welche einseitig durch das Rohr 16 miteinander verbunden sind. Die anderen Enden sind oben bzw. unten an die in den Endbereichen hohle Achse 1 über Rohre 17 angeschlossen. Die Zuführung des die ohrsysteme durchfließenden Mediums erfolgt beispielsweise von der unteren Kupplungseinrichtung 18, der Rücklauf dagegen durch die obere Kupplungseinrichtung 19.The vertical axis 1 of the Savonius rotor 2 is in radial bearings3 4 and 5 rotatably mounted. The axial forces are absorbed by thrust bearings 6 and 7. The lower bearing block 8 also serves to accommodate the through the Savonius rotor equipment to be operated, such as electrical power generators, pumps or the like, which can be driven, for example, via the belt pulley 9. The upper Bearing support 10 is braced to the ground by at least 3 ropes 11. In the In the form of semi-cylindrical shells, wings 12 and 13 each have inside a meandering pipe system 14 or 15, which on one side through the pipe 16 are connected to each other. The other ends are at the top or bottom of the ones in the End areas of the hollow axis 1 connected via pipes 17. The feeding of the ear systems medium flowing through takes place, for example, from the lower coupling device 18, while the return flow through the upper coupling device 19.

Die Rohrsysteme 14 und 15 sind durch Strahlungsbleche 20 miteinander verbunden, schwarz gefärbt und beidseitig durch strahlungs-durchlässige Isolierfolien 21, 22, 23 und 24 abgedeckt.The pipe systems 14 and 15 are connected to one another by means of radiation plates 20 connected, colored black and on both sides by radiation-permeable insulating foils 21, 22, 23 and 24 covered.
