Abstract

The rotor consists of a number of pressure members in the form of conical nozzles. They are open front and rear and are mounted on a carrier wheel revolving in a horizontal plane. The nozzle front, tapered end protrudes slightly into the rear end. Each wind pressure member (G) consists of two conical shells (12,13), mutually overlapping at the periphery. The inner shell (12) is firmly connected to the carrier wheel, while the outer shell (13) is pivotally mounted at the tapered end of the inner shell, the pivotal movement being carried out about an axis (15) coaxial with the carrier wheel. Each pressure nozzle has a limiter (20) for the pivotal angle of the outer shell. Pref. a radial rod (18) is mounted on the inner shell, passing through a slot (19) of the outer shell and carrying adjustable limiting stops.

Description

Bez. WtNDKRAFTRAD Die Erfindung betrifft ein Windkraftrad, bestehend aus einer Vielzahl von auf einem in einer waagerechten Ebene umlaufenden Trägerrad angeordneten, vorn und hinten offenen, als konische Düsen ausgebildeten Winddruckkörpern, deren jeweils vorderes, engeres Ende um ein geringes Maß in das hintere, weitere Ende des davor angeordneten Winddruckkörpers hineinragt.Bez. WtNDKRAFTRAD The invention relates to a wind turbine, consisting from a multitude of on a carrier wheel rotating in a horizontal plane arranged, front and rear open, designed as conical nozzles, wind pressure bodies, their front, narrower end by a small amount into the rear, wider one The end of the wind pressure body arranged in front of it protrudes.

Ein derartiges Windkraftrad ist durch das DE-GM 80 09 272 bekannt geworden. Wie bei vielen anderen Windkraftradern ergibt sich jedoch die Schwierigkeit, daß ein Teil der gewonnenen Windenergie durch den Luftwiderstand des gegen den Wind zurückkehrenden Teiles des Windkraftrades wieder verloren geht.Such a wind turbine is known from DE-GM 80 09 272 become. As with many other wind turbines, however, the difficulty arises that part of the wind energy gained by the air resistance of the against the wind returning part of the wind turbine is lost again.

Die Erfindung bezweckt, diesen Nachteil zu vermeiden, so daß das Windkraftrad mit besserem Wirkungsgrad betrieben werden kann.The invention aims to avoid this disadvantage, so that the wind turbine can be operated with better efficiency.

Die Lösung der gestellten Aufgabe besteht erfindungsgemäß darin, daß jeder Winddruckkörper aus zwei einander am Umfang überlappenden konischen Schalen besteht, daß die jeweils innere Schale fest mit dem Trägerrad verbunden und die jeweils äußere Schale am engeren Ende der inneren Schale um eine zur Trägerradachse koaxiale Achse schwenkbar angeordnet ist und daß jeder Winddruckkörper eine Einrichtung zur Begrenzung des Schwenkwinkels der äußeren Schale aufweist.According to the invention, the object is achieved in that Each wind pressure body consists of two conical shells that overlap each other on the circumference consists that the respective inner shell is firmly connected to the carrier wheel and the each outer shell at the narrower end of the inner shell around one to the carrier wheel axis coaxial axis is pivotably arranged and that each wind pressure body is a device to limit the pivoting angle of the outer shell.

Durch das Ausschwenken der äußeren Schale infolge der Zentrifugalkraftwird die luvseitige Querschnittsfläche des Winddruckkörpers stark vergrößert, ohne daß der leeseitige Austrittsquerschnitt aus jedem Winddruckkörper wesentlich verändert wird.The pivoting of the outer shell as a result of centrifugal force becomes the windward cross-sectional area of the wind pressure hull is greatly increased without the leeward exit cross-section from each wind pressure body changed significantly will.

Entgegen der Windrlchtung ist der Winddruckkörper dagegen relativ windschlüpfig -;ni bietet nur einen geringen Luftwiderstand.Contrary to the wind direction, the wind pressure body is relative streamlined -; ni offers only a low air resistance.

Das Windkraftrad ist von der Windrichtungunabhängig. Die dynamische uer-c'n i t;irlrlcillnci der e in7lnen Winddruckkörper erfolgt ohne zusätzlichen Energieaufwand und bewirkt einen erheblichen Wirkungsgradgewinn.The wind turbine is independent of the wind direction. The dynamic uer-c'n i t; irlrlcillnci the e in7lnen wind pressure body takes place without additional energy expenditure and causes a considerable gain in efficiency.

Nachstehend ist die Erfindung anhand eines in der Zeichnung dar gestellten Ausführungsbeispieles näher erläutert. Es zeigen: Fig.l eine Draufsicht auf ein Windkraftrad gemäß der Erfindung und Fig.2 einen vergrößerten Längsschnitt durch einen Winddruckkörper gemäß der Erfindung.The invention is based on one in the drawing is provided Embodiment explained in more detail. They show: Fig.l a plan view of a Wind turbine according to the invention and FIG. 2 shows an enlarged longitudinal section through a wind pressure hull according to the invention.

Fig. 1 zeigt ein Windkraftrad 1, bestehend aus einem Trägerrad 2 mit einer Nabe 3 für eine lotrecht anzuordnende Welle, Speichen 4 und einem Radkranz 5, auf dem eine Vielzahl, in der Zeichnung zehn Winddruckkörper 6 befestigt sind.Fig. 1 shows a wind turbine 1, consisting of a carrier wheel 2 with a hub 3 for a vertically arranged shaft, spokes 4 and a wheel rim 5, on which a plurality, ten in the drawing, wind pressure body 6 are attached.

Jeder Winddruckkörper 6 ist als vorn und hinten offene -kegelsturripf förmige Düse ausgebildet und steht mit seiner inneren, kürzesten Erzeugenden 7 tangential zum Trägerrad ?. Wie die Zeichnung zeit, ragt das enge Ende eines WinddruckkörDers 6 jeweils in das weite Ende des vorangehenden Winddruckkörpers 6 hinein, jedoch so, daß zwischen beiden Winddruckkörpern 6 ein Ringspalt gebildet ist.Each wind pressure body 6 is tapered as an open front and rear shaped nozzle and is tangential with its inner, shortest generating line 7 to the carrier wheel?. As the drawing shows, the narrow end of a wind pressure hull protrudes 6 each into the wide end of the preceding wind pressure hull 6, however so that an annular gap is formed between the two wind pressure bodies 6.

Die Winddruckkörper 6 sind jeweils aus zwei einander umfänglich überlappenden konischen Teilen, einer inneren und einer äußeren Schale 12 bzw. 13 gebildet, die durch eine Anlenkstelle 14 am engeren Ende des Winddruckkörpers 6 miteinander durch Achszapfen -15 verbunden sind, die koaxial zur Achse des Trägerrades 2 angeordnet sind.The wind pressure body 6 are each composed of two circumferentially overlapping conical parts, an inner and an outer shell 12 and 13, respectively, which through an articulation point 14 at the narrower end of the wind pressure body 6 with each other Axle journals -15 are connected, which are arranged coaxially to the axis of the carrier wheel 2 are.

Im Innern jedes Winddruckkörpers 6 ist etwa in Richtung der Strömungsachse ein Stromlinienkörper 9 angebracht, dessen spitzes Ende in die enge Uffnung des Winddruckkörpers 6 weist. Dieser Stromlinienkörper 9 ist an zwei fest mit der inneren Schale 12 verbundenen und diese ilt dem Trägerrad 2 verbindenden Stutzen 16 befestigt. Mittels Muttern 17,18 ist sowohl die radiale Laqe der inneren Schale als uch des Stromlinienkörpers 9 verstellb.lr.Inside each wind pressure body 6 is approximately in the direction of the flow axis a streamlined body 9 attached, the pointed end in the narrow opening of the Wind pressure body 6 has. This streamlined body 9 is fixed at two to the inner one Shell 12 connected and this ilt the carrier wheel 2 connecting stub 16 is attached. Both the radial position of the inner shell and the Streamlined body 9 adjustable left.

Am Stromlinienkörper 9 ist eine radial nach außen weisende Ge windestange 18 befestigt, die durch einen Schlitz 19 in der außer Schale 13 ragt und ,r, ihrltln Knde eine Mutter 20 trägt. Diese dient als Begrenzungsanschlag fur den in der Zeichnung strichpunktiert dargestellten Schwenkbereich der äußeren Schale 13 in Bezug auf die innere Schale 12.On the streamlined body 9 is a radially outward facing Ge threaded rod 18 attached, which protrudes through a slot 19 in the outer shell 13 and, r, ihrltln Knde a mother 20 wears. These serves as a limit stop for the pivoting range of the outer shell shown in dash-dotted lines in the drawing 13 in relation to the inner shell 12.

Die Winddruckkörper ergeben auf gerinqem Raum eine relativ große Beaufschlagungsfläche und erfordern nur kurze Hebelarme. Gegenüber der eingangs erwähnten bekannten Ausführung erfolgt luvseitig, wie in Fig. 1 unten angege-ben, eine Vergrößerung der Beaufschlagungsfläche dadurch, daß die äußeren Schalen 13 infolge der gemeinsamen Wirkung von Zentrifugalkraft und Windkraft nach außen schwenken und dem Winddruckkorper eine größere Beaufschlagungsfläche vermitteln, während sich die äußeren Schalen 13 des rückkehrenden Teiles des Windkraftrades 1 infolge der Einwirkung der Windkraft gegen die inneren Schalen 12 anlegen.The wind pressure bodies result in a relatively large impact area in a small space and only require short lever arms. Compared to the known design mentioned at the beginning takes place on the windward side, as indicated in Fig. 1 below, an enlargement of the impact area in that the outer shells 13 as a result of the combined action of centrifugal force and wind power swing outwards and the wind pressure body a larger area of application mediate, while the outer shells 13 of the returning part of the wind turbine 1 due to the action of the wind force against the inner shells 12.

m diese Wirkung zu unterstützen, können zusätzlich an der Gewindestange 18 Federn 21 befestigt sein, die der Wirkung der Zentrifugalkraft entgegenwirken. Die Federn können in bekannter Weise in ihrer Federstärke verstellbar angeordnet sein.To support this effect, you can also use the threaded rod 18 springs 21 be attached, which counteract the effect of centrifugal force. The springs can be arranged to be adjustable in their spring strength in a known manner be.
