Abstract
Torsionsrohr für schwenkbaren Sonnenstandsnachführung mit verschweissten Flanschen und verschweissten Laschen zur Befestigung von Solarmodultragprofilen. dadurch gekennzeichnet, dass die Laschen beidseitig und symetrisch am Torsionsrohr verschweisst sind und damit keinen Schweissverzug verursachen.Torsion tube for swiveling sun position tracking with welded flanges and welded lugs for fixing solar module support profiles. characterized in that the tabs are welded on both sides and symmetrically on Torsionsrohr and thus cause no welding distortion.
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 mittels eines sogenannten Modultragprofils auf einen in Nord-Südrichtung ausgerichtetes in Ost- und Westrichtung schwenkbares Torsionsrohr befestigt. Diese sogenannten Torsionsrohre werden zunehmend zur Fundamentierung an sogenannte Rammfundamente befestigt, welche mittels einer Rammmaschine in den Boden getrieben werden. Aus Kostengründen wird dieser Konstruktionsaufbau vorzugsweise so lang wie möglich mit mehreren in Nord-Südrichtung verbundenen Torsionsrohren ausgeführt. Die statisch anzusetzenden Windasten erzeugen erhebliche Torsionskräfte welche bei der Verbindung mehrerer Torsionsrohre vom Torsionsrohr auf die Verbindungselemente übertragen werden muss. Weiterhin muss die Verbindung der Modultragprofile mit dem Torsionsrohr hohe lokale Lasten aufnehmen können. Für beide Verbindungen werden entweder Klemmverbindungen verwendet, welche den Nachteil haben, dass sie in der Ausführung mit witrschaftlich vertretbaren Kosten ungenau und nicht spielfrei sind, was der Genauigkeit der Nachführung entgegensteht. Oder es werden Schweissverbindungen verwendet, welche den Nachteil haben, dass sie teuer in der Fertigung sind und zu einem Verzug des Torsionsrohres führen können, was wiederum zu Ungenauigkeiten des Nachführungswinkels führt.As a particularly cost-effective design photovoltaic modules are mounted by means of a so-called module support profile on a north-south oriented in the east and west direction pivotable torsion 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. 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 statically applied wind loads generate considerable torsional forces which must be transmitted from the torsion tube to the connecting elements in the connection of several torsion tubes. Furthermore, the connection of the module support profiles with the torsion tube must be able to absorb high local loads. For both compounds either clamping connections are used, which have the disadvantage that they are imprecise and not free of play in the execution with witrschaftlich reasonable costs, which precludes the accuracy of the tracking. Or welding joints are used, which have the disadvantage that they are expensive to manufacture and can lead to a distortion of the torsion tube, which in turn leads to inaccuracies of the tracking angle.
Die folgende Erfindung mit den in den Schutzansprüchen 1–4 aufgeführten Merkmalen stellt eine verzugsfreie und wirtschaftliche schweissbaren Verbindung der Modultragschienen an das Torsionsrohr dar, welche statisch vorteilhaft angeordnet ist. Weiterhin stellt sie eine wirtschaftlich vorteilhafte und prozesssichere Verbindung der Torsionsrohre dar.The following invention with the features listed in the claims 1-4 provides a distortion-free and economical weldable connection of the module support rails to the torsion tube, which is arranged statically advantageous. Furthermore, it represents an economically advantageous and process-reliable connection of the torsion tubes.
