- the mechanical coupling of the two rotary movements is advantageously carried out via an articulated but rigidly spaced connection of the flat carrier at a point spaced from the horizontal first axis of rotation via a spacer articulated on both sides with a fixed fixing element spaced from the vertical second axis of rotation. If, as part of the tracking, the carrier and the horizontal first axis of rotation, which is firmly connected to the flat carrier, is rotated about the vertical second axis of rotation and the articulated spacer supports engages at the point spaced from the horizontal first axis of rotation, then the articulated spacer supports moves connected point on a circular path, which is part of the enveloping sphere of the spacer element fixedly attached on one side.

Die Erfindung betrifft eine Nachführvorrichtung, zur Nachführung eines Kollektors, Absorbers, Reflektors oder Photovoltaikmoduls nach dem Stand der Sonne, mit einem um eine erste Drehachse und eine zweite Drehachse drehbaren flächigen Träger.The invention relates to a tracking device for tracking a collector, absorber, reflector or photovoltaic module according to the position of the sun, with a flat carrier rotatable about a first axis of rotation and a second axis of rotation.
Derartige Vorrichtungen sind bereits in zahlreichen Varianten bekannt. Vielerorts werden Sonnenstrahlen mittels nachführbarer Sonnenkollektoren auf zentrale Energieerzeuger gerichtet oder Photovoltaik-Elemente zur Wirkungsgraderhöhung der Sonne nachgeführt. Ein Nachführen solcher Sonnenkollektoren ist mit einer ungleich höheren Effizienz gegenüber nicht nachgeführten Kollektoren verbunden.Such devices are already known in numerous variants. In many places, the sun's rays are directed to central energy generators by means of trackable solar collectors, or photovoltaic elements are tracked to increase the sun's efficiency. Tracking of such solar collectors is associated with an incomparably higher efficiency than collectors that are not tracked.
Die bisherigen Methoden zur Nachführung derartiger Kollektoren sind jedoch äußerst aufwendig und daher kostspielig. In der Regel wird eine teure Hydraulik, Pneumatik oder mittels Servomotoren in mehreren Achsen angetriebene Mechanik benötigt, um einzelne Sonnenkollektoren der Sonne nachzuführen. Wirtschaftlich betrachtet sind bisherige Lösungen zur Nachführung von Sonnenkollektoren ungünstig und daher ist eine derartige Nutzung der Sonnenenergie anderen Methoden zur Energieerzeugung unterlegen. Aus diesem Grund finden sich nachgeführte Sonnenkollektoren nahezu ausschließlich im wissenschaftlichen Bereich zu Versuchszwecken und bei Anlagen zur Demonstration. Für eine Nutzung der Sonnenenergie, für die wirtschaftliche Erwägungen im Vordergrund stehen, ist eine Nachführung der Sonnenkollektoren bisher nicht realisierbar. Eine Vorrichtung zum Nachführen von Sonnenkollektoren ist zum Beispiel bereits aus der Offenlegungsschrift DE 29 50 734 A1 bekannt. Der vorgeschlagene Sonnenkollektor ist in mehreren Achsen beweglich und kann über eine äußerst aufwendige angetriebene Mechanik exakt der Sonne nachgeführt wer- den. Der hohe konstruktive und bauliche Aufwand eines solchen Sonnenkollektors steht der Wirtschaftlichkeit dieser Art der Nutzung der Sonnenenergie entgegen.The previous methods for tracking such collectors are extremely complex and therefore costly. As a rule, expensive hydraulics, pneumatics, or mechanics driven by servomotors in several axes are required to track individual solar collectors to the sun. From an economic point of view, previous solutions for tracking solar collectors are unfavorable and therefore such use of solar energy is inferior to other methods of energy generation. For this reason, tracking solar collectors can be found almost exclusively in the scientific field for experimental purposes and in systems for demonstration. So far, it has not been possible to track the solar collectors for using solar energy, for which economic considerations are paramount. A device for tracking solar collectors is already known, for example, from the published patent application DE 29 50 734 A1. The proposed solar collector can be moved in several axes and can be exactly tracked to the sun by an extremely complex driven mechanism. The high structural and structural outlay of such a solar collector conflicts with the economic viability of this type of use of solar energy.
Ausgehend von den Nachteilen und Problemen des Standes der Technik liegt der Erfindung die Aufgabe zugrunde, eine Nachführvorrichtung zur Nutzung der Sonnenenergie zu schaffen, welche kostengünstig herzustellen ist, einen geringen Wartungsaufwand während des Betriebs aufweist und eine hohe Lebensdauer mit sich bringt.Based on the disadvantages and problems of the prior art, the invention has for its object to provide a tracking device for using solar energy, which is inexpensive to manufacture, requires little maintenance during operation and has a long service life.
Erfindungsgemäß wird die Aufgabe durch eine Nachführvorrichtung der eingangs genannten Art gelöst, bei welcher die Drehbewegung des flächigen Trägers um die erste Drehachse mechanisch an die Drehbewegung um die zweite Drehachse gekoppelt ist. Weiterhin ist eine Nachführvorrichtung der eingangs genannten Art Gegenstand der Erfindung, bei welcher die erste Drehachse im wesentlichen horizontal und die zweite Drehachse im wesentlichen vertikal verläuft, der flächige Träger an wenigstens zwei Auflagerpunkten in der ersten Drehachse drehbar an einem Aufnahmeträger befestigt ist und der Aufnahmeträger drehbar um die vertikale Drehachse an einem Standpfeiler befestigt ist.According to the invention, the object is achieved by a tracking device of the type mentioned in the introduction, in which the rotary movement of the flat carrier about the first axis of rotation is mechanically coupled to the rotary movement about the second axis of rotation. Furthermore, a tracking device of the type mentioned is the subject of the invention, in which the first axis of rotation runs essentially horizontally and the second axis of rotation runs essentially vertically, the flat carrier is rotatably attached to a receiving carrier at at least two support points in the first axis of rotation and the receiving carrier is rotatable is attached to a pillar about the vertical axis of rotation.
Die vorgeschlagene mechanische Kopplung der beiden Drehbewegungen an einander hat den besonderen Vorteil, daß nicht für jede Drehbewegung ein separater Antrieb benötigt wird, sondern beide Drehbewegungen den gleichen Antrieb nutzen können. Die mechanische Kopplung verleiht dem System darüber hinaus zusätzliche Stabilität.The proposed mechanical coupling of the two rotary movements to one another has the particular advantage that a separate drive is not required for each rotary movement, but that both rotary movements can use the same drive. The mechanical coupling also gives the system additional stability.
Der besondere Vorteil des erfindungsgemäßen Aufnahmeträgers liegt in der erstmalig kostengünstigen Realisierung einer Nachführvorrichtung. Der Aufnahmeträger ermöglicht es, die angreifenden Windlasten unter Vermeidung hoher Biegemomentbelastung auf den Standpfeiler zu übertragen. Für eine geeignete, an die Sonnenlaufbahn angepaßte Nachführung ist es zweckmäßig, wenn die erste Drehachse horizontal und die zweite Drehachse vertikal verläuft. Auf diese Weise kann über die horizontale erste Drehachse der Neigungswinkel des flächigen Trägers an den Einstrahlwinkel der Sonne auf die Erde angepaßt werden und über die vertikale Achse die Erdrotation berücksichtigt werden.The particular advantage of the receiving carrier according to the invention lies in the first time cost-effective implementation of a tracking device. The mounting bracket enables the attacking wind loads to be transferred to the pillar while avoiding high bending moment loads. For a suitable tracking adapted to the sun's running path, it is expedient if the first axis of rotation runs horizontally and the second axis of rotation runs vertically. In this way, the inclination angle of the planar support can be adapted to the angle of incidence of the sun on the earth via the horizontal first axis of rotation and the earth's rotation can be taken into account via the vertical axis.
Erfindungsgemäß ist es besonders vorteilhaft, wenn die Verstellung der Neigung des flächigen Trägers an die Drehbewegung um die vertikale zweite Drehachse gekoppelt ist. Daher ist es sinnvoll, die horizontale erste Drehachse fest mit dem Träger zu verbinden und die vertikale zweite Drehachse ortsfest zu wählen.According to the invention, it is particularly advantageous if the adjustment of the inclination of the flat carrier is coupled to the rotary movement about the vertical second axis of rotation. It is therefore sensible to connect the horizontal first axis of rotation to the support and to select the vertical second axis of rotation in a stationary manner.
Die mechanische Kopplung der beiden Drehbewegungen erfolgt vorteilhaft über eine gelenkige aber abstandsstarre Verbindung des flächigen Trägers an einer von der horizontalen ersten Drehachse beabstandeten Stelle über eine beidseitig gelenkig angebrachte Distanzstütze mit einem raumfesten, von der vertikalen zweiten Drehachse beabstandeten Befestigungselement. Wird im Rahmen der Nachführung der Träger und die fest mit dem flächigen Träger verbundene horizontale erste Drehachse um die vertikale zweite Drehachse gedreht und greift an der von der horizontalen ersten Drehachse beabstandete Stelle die gelenkig angebrachte Distanzstütze an, so bewegt sich die mit der gelenkig angebrachten Distanzstüzte in Verbindung stehende Stelle auf einer Kreisbahn, welche Bestandteil der umhüllenden Sphäre des einseitig ortsfest angebrachten Distanzelementes ist. Abhängig von der Länge des Distanzelementes stellt sich somit eine gewünschte maximale und minimale Neigung des flächigen Trägers abhängig von der augenblicklichen Winkelstellung bezüglich der vertikalen zweiten Drehachse ein.The mechanical coupling of the two rotary movements is advantageously carried out via an articulated but rigidly spaced connection of the flat carrier at a point spaced from the horizontal first axis of rotation via a spacer articulated on both sides with a fixed fixing element spaced from the vertical second axis of rotation. If, as part of the tracking, the carrier and the horizontal first axis of rotation, which is firmly connected to the flat carrier, is rotated about the vertical second axis of rotation and the articulated spacer supports engages at the point spaced from the horizontal first axis of rotation, then the articulated spacer supports moves connected point on a circular path, which is part of the enveloping sphere of the spacer element fixedly attached on one side. Depending on the length of the spacer element, a desired maximum and minimum inclination of the flat carrier is thus set depending on the instantaneous angular position with respect to the vertical second axis of rotation.
Damit die Nachführung bedarfsgerecht an die verschiedenen Jahreszeiten angepaßt werden kann und so beispielsweise der tiefere Stand der Herbstsonne gegenüber dem sommerlichen Niveau berücksichtigt werden kann, ist es sinnvoll, die Distanzstütze in ihrer Länge verstellbar auszubilden. Dies kann beispielsweise über ein Gewinde erfolgen, welches in regelmäßigen Abständen händisch nachjustiert wird. Die Längenverstellung der Distanzstütze kann auch motorisch angetriebenen sein, beispielsweise mittels eines Elektromotors. Dies würde zusätzlich eine permanente Feinjustage der Winkelstellung des flächigen Trägers ohne händischen Eingriff ermöglichen. Die erhöhte Präzision der Nachführung hätte eine weitere Erhöhung des Wirkungsgrades zur Folge. Eine derartige Einflußnahme auf die Nachführung ließe sich vorteilhaft zentral steuern. Die erfindungsgemäßen Vorteile, nämlich die Einsparung einer teuren, komplizierten Nachführung, bleiben dennoch erhalten, da es sich bei der zusätzlichen motorischen Verstellmöglichkeit nur um ein Modul zur Feinjustage handelt, welches aufgrund des nur kleinen Arbeitsweges kostengünstig kompakt ausgeführt werden kann.So that the tracking can be adapted to the different seasons as required and so, for example, the lower position of the autumn sun compared to the summer level can be taken into account, it makes sense to design the distance support to be adjustable in length. This can be done, for example, via a thread, which is readjusted manually at regular intervals. The length adjustment of the spacer support can also be motor-driven, for example by means of an electric motor. This would also allow permanent fine adjustment of the angular position of the flat beam without manual intervention. The increased precision of the tracking would result in a further increase in efficiency. Such an influence on the tracking could advantageously be controlled centrally. The advantages according to the invention, namely the saving of an expensive, complicated tracking, are still retained, since the additional motorized adjustment option is only a module for fine adjustment, which can be made inexpensively compact due to the short travel distance.
Besonders vorteilhaft ist eine beidseitige Befestigung des flächigen Trägers in seiner horizontalen ersten Drehachse drehbar in mindestens zwei Auflagerpunkten an einem Aufnahmeträger. Auf diese Weise ist es insbesondere möglich, daß die horizontale erste Drehachse und die vertikale zweite Drehachse in etwa durch den Schwerpunkt des Trägers verlaufen. Diese Anordnung ist im Hinblick auf die Statik der Vorrichtung besonders vorteilhaft, weil die schwerpunktmäßige Lagerung das Aufkommen von Momenten und Querkräften minimiert. Sowohl die statischen Bauteile, als auch die Lagerungen sind somit minimaler Belastung ausgesetzt.It is particularly advantageous to fasten the flat support on both sides in its horizontal first axis of rotation, rotatable in at least two support points on a receiving support. In this way, it is in particular possible that the horizontal first axis of rotation and the vertical second axis of rotation run approximately through the center of gravity of the carrier. This arrangement is particularly advantageous with regard to the statics of the device, because the main focus minimizes the occurrence of moments and transverse forces. Both the static components and the bearings are therefore exposed to minimal stress.
Eine besonders robuste und einfache drehbare Lagerung des Aufnahmeträgers ergibt sich, wenn dieser sich in seiner Mitte auf einer Konusspitze abstützt, welche das obere Ende eines ortsfesten Standpfeilers bildet. Die Lagerung auf einer Konusspitze ist weitaus kostengünstiger als jede Form der Wälzlagerung. Angesichts der niedrigen Lagerbelastung hinsichtlich der quasi statischen Bewegung ist diese Anordnung konstruktiv sinnvoll und wirtschaftlich äußerst günstig. Diese höchst einfache Form der Gleitlagerung ist zudem sehr wartungsarm und zuverlässig.A particularly robust and simple rotatable mounting of the receiving carrier is obtained if it is supported in the middle on a cone tip, which forms the upper end of a stationary pillar. Bearing on a cone tip is much cheaper than any form of rolling bearing. In view of the low bearing load with regard to the quasi-static movement, this arrangement is constructively sensible and economically extremely cheap. This extremely simple form of plain bearing is also very low-maintenance and reliable.
Der große Vorteil der erfindungsgemäßen Nachführvorrichtung entfaltet sich erst gänzlich beim Einsatz einer Vielzahl dieser Vorrichtungen. Vorteilhaft lassen sich mehrere gleichartige Vorrichtungen in einer Reihe mit Zugmitteln verbinden und die Winkeleinstellung mittels eines Stellantriebs über das Zugmittel vornehmen. Hierbei ist es zweckmäßig, den Aufnahmeträger mit einer um die vertikale zweite Drehachse zylindrisch gebogenen seitlichen Zugmittelführung auszustatten, über welche Zugmittel geführt werden, mittels derer die Winkelstellung in der vertikalen zweiten Drehachse eingestellt wird. Auf diese Weise können beispielsweise 50 erfindungsgemäße Nachführvorrichtungen mit nur einem Stellantrieb der Sonne nachgeführt werden. Auf der dem Stellantrieb gegenüberliegenden Seite eines Zugmittels kann mittels eines Gegengewichts die stets stabile Winkelposition der Nachführvorrichtungen gewährleistet werden. Statt eines Zugmittels können auch starre Verbindungen zwischen dem Stellantrieb und den Nachführvorrichtungen, beziehungsweise den Nachführvorrichtungen untereinander vorgesehen werden.The great advantage of the tracking device according to the invention only fully unfolds when a large number of these devices are used. Advantageously, several devices of the same type can be connected in a row with traction means and the angle can be adjusted by means of an actuator via the traction means. In this case, it is expedient to mount the receptacle with a lateral traction means guide cylindrically curved about the vertical second axis of rotation to equip via which traction means are guided, by means of which the angular position in the vertical second axis of rotation is set. In this way, for example, 50 tracking devices according to the invention can be tracked with only one actuator of the sun. On the side of a traction device opposite the actuator, the always stable angular position of the tracking devices can be ensured by means of a counterweight. Instead of a traction device, rigid connections between the actuator and the tracking devices, or the tracking devices with one another, can also be provided.
Im folgenden wird anhand eines Ausführungsbeispiels unter Bezugnahme auf Zeichnungen die Erfindung näher verdeutlicht. Es zeigt:The invention will be explained in more detail below using an exemplary embodiment with reference to drawings. It shows:
Fig. 1: Eine perspektivische Darstellung einer erfindungsgemäßen Nachführvorrichtung.Fig. 1: A perspective view of a tracking device according to the invention.
Die erfindungsgemäße Nachführvorrichtung ist in Figur 1 mit der Bezugsziffer 1 bezeichnet. Sie besteht im wesentlichen aus einem Träger 2, einem Aufnahmeträger 3 und einem Standpfeiler 4.The tracking device according to the invention is designated by the reference number 1 in FIG. It essentially consists of a carrier 2, a receiving carrier 3 and a pillar 4.
Der Träger 2 besteht im wesentlichen aus zwei Längsprofilen, die den Träger zu zwei Seiten hin abschließend begrenzen und zwei Querprofilen, welche jeweils im Abstand von etwa einem Drittel der Länge der Längsprofile an den Längsprofilen angebracht sind. Durch eine Hauptträgheitsachse parallel zu den Längsprofilen 2a verläuft eine erste horizontale Drehachse, in welcher der Träger 2 an der Rahmenkonstruktion des Aufnahmeträgers 3 angebracht ist. Am unteren Rand des rahmenförmigen Aufnahmeträgers 3 ist eine Zugmittelführung 8 angebracht, welche im Halbkreis zylindrisch gebogen ist. An der horizontal ausgerichteten halbkreisförmigen Zugmittelführung 8 ist ein nicht dargestelltes Zugmittel angebracht.The carrier 2 consists essentially of two longitudinal profiles which finally delimit the carrier on two sides and two transverse profiles, which are each attached to the longitudinal profiles at a distance of approximately one third of the length of the longitudinal profiles. A first horizontal axis of rotation, in which the carrier 2 is attached to the frame structure of the receiving carrier 3, runs through a main axis of inertia parallel to the longitudinal profiles 2a. At the lower edge of the frame-shaped receiving support 3, a traction means guide 8 is attached, which is cylindrically curved in a semicircle. A traction means, not shown, is attached to the horizontally oriented semicircular traction means guide 8.
Durch die vertikale Hauptträgheitsachse des Aufnahmeträgers 3 verläuft eine vertikale zweite Drehachse 9. Die vertikale zweite Drehachse 9 ist in etwa so ausgerichtet, daß sie sich mit der horizontalen ersten Drehachse 7 schneidet. Der Aufnahmeträger 3 ist auf dem Standpfeiler 4 in der vertikalen zweiten Drehachse 9 mittig gelagert. Die Lagerung erfolgt über eine am oberen Ende des Standpfeilers 4 befindliche Konusspitze 10.A vertical second axis of rotation 9 runs through the vertical main axis of inertia of the receiving carrier 3. The vertical second axis of rotation 9 is approximately aligned such that it intersects with the horizontal first axis of rotation 7. The receiving support 3 is mounted on the pillar 4 in the middle of the vertical second axis of rotation 9. Storage takes place via a cone tip 10 located at the upper end of the pillar 4.
Der rahmenförmige Aufnahmeträger besteht im wesentlichen aus einem obe- ren 11 und einem unteren Querholm 12 sowie zwei seitlichen Trägern 13, 14. Der untere Querholm 12 ist mit einer Durchführung für den Standpfeiler 4 versehen, welcher am oberen Ende in eine Konusspitze 10 mündet, die zur Aufnahme der Aufstandskraft des Trägers 2 dient. Etwaige Querkräfte aus beispielsweise einer Windbelastung werden sowohl durch die Konusspitze 10 als auch über die Lagerung an der Durchführung 15 aufgenommen.The frame-shaped support beam consists essentially of an upper 11 and a lower cross member 12 and two side supports 13, 14. The lower cross member 12 is provided with a passage for the pillar 4, which opens into a cone tip 10 at the upper end, which serves to absorb the contact force of the carrier 2. Any transverse forces from, for example, a wind load are absorbed by the cone tip 10 as well as by the bearing on the bushing 15.
An dem Standpfeiler 4 ist ein Befestigungselement 16 angebracht, welches mit einer Distanzstütze 17 in Verbindung steht, die sowohl an dem Befestigungselement 16 als auch an dem Träger 2 gelenkig angebracht ist.A fastening element 16 is attached to the pillar 4, which is connected to a spacer 17, which is articulated both on the fastening element 16 and on the carrier 2.
Wird die dargestellte Nachführvorrichtung 1 mittels des nicht dargestellten Zug- mittels gedreht, findet gleichzeitig eine Veränderung der Neigung des Trägers 2 statt.If the tracking device 1 shown is rotated by means of the traction means, not shown, a change in the inclination of the carrier 2 takes place at the same time.
Die Distanzstütze 17 ist in ihrer Länge verstellbar, so daß eine Feinjustage des überstrichenen Neigungswinkels abhängig von der Jahreszeit durchgeführt werden kann.The distance support 17 is adjustable in length, so that a fine adjustment of the swept angle of inclination can be carried out depending on the season.
Die gesamte Nachführvorrichtung 1 ist in gewöhnlichem Baustahl als Schweißkonstruktion hergestellt und oberflächenverzinkt. The entire tracking device 1 is made of common structural steel as a welded construction and is galvanized on the surface.
