Description
Aufgrund des globalen Witrschaftswachstums wird stetig mehr Energie, insbesondere Elektrizität benötigt. Aufgrund von Ressoaurcenknappheit fällt erneuerbaren Energien, wie der Photovoltaik eine zunehmende Bedeutung zu. Da sich die tägliche Ertragskurve bei fest aufgeständerten Photovoltaikmodulen, welche erst zur Mittagszeit seinen Höchstwert erreicht, nicht günstig dem täglichen Strombedarf deckt, werden zunehmend sonnenstandsnachgeführte Systeme realisiert.Due to global economic growth, more and more energy is needed, especially electricity. Due to a lack of resources, renewable energies such as photovoltaics are becoming increasingly important. Since the daily yield curve for fixed-mounted photovoltaic modules, which only reaches its maximum value at lunchtime, does not meet the daily demand for electricity, sun-tracking systems are increasingly being implemented.
Als besonders kostengünstige Konstruktion werden Photovoltaikmodule auf einen in Nord-Südrichtung ausgerichtetes in Ost- und Westrichtung schwenkbares Rohr befestigt. Diese sogenannten Torsionsrohre werden zunehmend zur Fundamentierung an sogenannte Rammfundamente befestigt, welche mittels einer Rammmaschine in den Boden getrieben werden. Um die Drehbewegung zu gewährleisten werden Lager benötigt, welche die Torsionswelle auf den Rammfundamenten in Position hält und eine Schwenkbewegung um die Achse der Torsionswelle ermöglicht. Aus Kostengründen wird dieser Konstruktionsaufbau vorzugsweise so lang wie möglich mit mehreren in Nord-Südrichtung verbundenen Torsionsrohren ausgeführt. Die Konstruktion muss deshalb bauseitige Toleranzen ausgleichen können. Die statisch anzusetzenden Windasten erzeugen erhebliche Kräfte welche über die Lager auf die Rammfundmante übertragen werden muss. Üblicherweise werden die Torsionsrohr umfassende Kunststoffgleitlager verwendet, welche aber Schmutz-, und frostempfindlich sind und beim Anfahren der Bewegung ein erhebliches Losbrechmoment überwinden müssen, was häufig zu einer ungleichhmässigen ratternden Bewegung führen kann. Weiterhin wird durch Abrieb die Oberfläche des Torsionsrohr in seiner Korrosionsschutzeigenschaft ungünstig beeinflusst.As a particularly cost-effective design photovoltaic modules are mounted on a north-south oriented aligned in the east and west direction pivotable tube. These so-called torsion tubes are increasingly being used for foundation on so-called Rammfundamente fixed, which are driven by a piling machine in the ground. In order to ensure the rotational movement bearings are required, which holds the torsion shaft on the Rammfundamenten in position and allows a pivoting movement about the axis of the torsion shaft. For cost reasons, this design structure is preferably carried out as long as possible with a plurality of torsion tubes connected in north-south direction. The design must therefore be able to compensate for on-site tolerances. The statically attached wind loads generate considerable forces which must be transmitted via the bearings on the Rammfundmante. Usually, the torsion tube comprehensive plastic plain bearings are used, but which are dirt and frost-sensitive and must overcome a significant breakaway torque when starting the movement, which can often lead to uneven rattling movement. Furthermore, the surface of the torsion tube is adversely affected by abrasion in its anticorrosive property.
Die folgende Erfindung mit den in den Schutzansprüchen 1–3 aufgeführten Merkmalen stellt eine Lagerung von Torsionswellen zur Sonnenstandsnachführung von Photovoltaikmodulen oder anderen flächenförmigen Bauteilen mit aussenliegenden Rollen dar, welche unter Verwendung einer schwenkbaren Vorrichtung in der Lagerhalterung einen Ausgleich der Winkelabweichungen von den Torsionswellen in Ost-Westrichtung, in Nord-Südrichtung und Winkelabweichung der Rammfundamente oder anderer Fundamente ermöglicht.The following invention with the features listed in the claims 1-3 represents a storage of torsion for Sonnenstandsnachführung of photovoltaic modules or other sheet-like components with external rollers, which using a pivotable device in the bearing bracket balancing the angular deviations of the torsion waves in eastern West direction, in north-south direction and angular deviation of Rammfundamente or other foundations allows.
