Description
Parabolspiegel für Sonnenenergieanlagen Parabolic mirrors for solar energy systems
Die Erfindung bezieht sich auf einen Parabolspiegel gemäß dem Gattungsbegriff des Anspruches 1.The invention relates to a parabolic mirror according to the generic term of claim 1.
Konzentrierende Kollektoren mit Parabolspiegeln, wie Zylinderparabolspiegeln, für die Nutzung von Sonnenergie werden häufig nicht mit Glasplatten abgedeckt. Sie sind dann der Witterung, Regen und Wind ausgesetzt. Es kommt zur Ablagerung von Feststoffen, von Blütenpollen bis zum Sand. Dies beeinträchtigt die Reflexion der Sonnenstrahlung, eine Reinigung der Spiegeloberfläche wird notwendig.Concentrating collectors with parabolic mirrors, such as cylindrical parabolic mirrors, for the use of solar energy are often not covered with glass plates. she are then exposed to the weather, rain and wind. Deposition of Solids, from bee pollen to sand. This affects the reflection of the Solar radiation, cleaning of the mirror surface becomes necessary.
Bei größeren Anlagen ist eine Reinigung von Hand nicht mehr möglich; ein Abspritzen mit einem Wasserschlauch ist auch nicht mehr rationell.In the case of larger systems, cleaning by hand is no longer possible; hosing down with a water hose is also no longer efficient.
Aufgabe der Erfindung ist die Ausgestaltung eines gattungsgemäßen Parabolspiegels mit einer einfachen und zweckmäßigen Reinigung des Spiegels.The object of the invention is to design a generic Parabolic mirror with a simple and practical cleaning of the mirror.
Die Aufgabe wird mit der Erfindung gelöst, deren Merkmale sich aus den Patentansprüchen ergeben.The object is achieved with the invention, the features of which are derived from the claims result.
Ein Parabolspiegel mit den erfindungsgemäßen Merkmalen weist gegenüber konventionellen Parabolspiegeln nur einen relativ geringen baulichen Mehraufwand auf. Er hat jedoch den Vorteil, daß er jederzeit ohne Probleme gereinigt werden kann, also jederzeit in optimaler Weise die Sonnenenergie reflektieren kann. Die Steuerung der Reinigung kann dabei nach einem festen Programm automatisch in regel- oder unregelmäßigen Zeitabständen, oder individuell bei vorliegendem Bedarf erfolgen. Die Umsetzbarkeit der Waschanlage ermöglicht deren besonders rationellen Einsatz, indem mehrere Spiegel mit ein und derselben Waschanlage bedient werden können. Ähnlich, wie bei Waschanlagen von beispielsweise Kfz-Scheinwerfern kann die Wirksamkeit der erfindungsgemäßen Waschanlage durch mechanische Hilfsmittel, wie beispielsweise Wischer oder Bürsten, intensiviert werden.A parabolic mirror with the features according to the invention has opposite conventional parabolic mirrors only require relatively little additional structural effort on. However, it has the advantage that it can be cleaned at any time without any problems can, i.e. can optimally reflect solar energy at any time. the Cleaning can be controlled automatically according to a fixed program in regular or at irregular intervals, or individually if required. The feasibility of the washing system enables it to be used particularly efficiently, in that several mirrors can be operated with one and the same washing system. Similar, as with car wash systems, for example, can reduce the effectiveness of the washing system according to the invention by mechanical aids, such as Wipers or brushes, to be intensified.
Ein Ausführungsbeispiel für eine Waschanlage gemäß der Erfindung ist nachfolgend anhand der Zeichnung erläutert.An embodiment of a washing system according to the invention is explained below with reference to the drawing.
Einer von vielen Parabolspiegeln, insbesondere Zylinderparabolspiegeln, einer Sonnenenergieanlage ist mit 1 bezeichnet. Handelt es sich um einen zylindrischen Spiegel, so ist er an zwei parallelen Längsseiten in einer erfindungsgemäß ausgestatteten Haltekonstruktion 2 aufgehängt. Die Haltekonstruktion weist zwei parallele Leisten 3, 4 auf, deren Oberseiten als Laufschienen 5, 6 für Rollen 7 ausgebildet sind. Den Rollen 7 sind mit Spurkränzen 16 versehene winkelförmige Elemente 8 zur seitlichen Führung auf den Laufschienen zugeordnet. Die Rollen sind drehbar an den gegenüberliegenden Seiten des Waschanlagengerüstes 9 gelagert. An dem Waschanlagengerüst 9 sind zwei Halterungen 10, 11 befestigt, die auf die Spiegelreflexionsflächen gerichtete Sprühdüsen 12 tragen. Die Halterungen 10, 11 sind hohle Rohre, so daß durch sie die Reinigungsflüssigkeit den Sprühdüsen 12 zugeführt werden kann. Die Zufuhr der Reinigungsflüssigkeit zu den Halterungen 10, 11 erfolgt mittels einer Verrohrung 13 von einem Ende eines Schlauches 14 aus. Der Schlauch 14 ist in einer der zu diesem Zweck rinnenförmigen Laufschienen 5, 6 verlegt und wird entsprechend der Gerüstbewegung auf eine Trommel eines Reinigungsmittel speichers aufgewickelt oder von dieser Trommel abgewickelt, die eine Kupplung zwischen dem anderen Schlauchende und dem Reinigungsspeicher darstellt.One of many parabolic mirrors, especially cylindrical parabolic mirrors, a solar energy system is denoted by 1. Is it a cylindrical one? Mirror so he's at two parallel long sides in one according to the invention equipped support structure 2 suspended. The support structure has two parallel strips 3, 4, the tops of which act as running rails 5, 6 for rollers 7 are trained. The rollers 7 are angular elements provided with flanges 16 8 assigned to the lateral guidance on the rails. The rollers are rotatable mounted on the opposite sides of the washing plant frame 9. On the car wash frame 9, two brackets 10, 11 are attached, which are directed towards the mirror reflection surfaces Wear spray nozzles 12. The brackets 10, 11 are hollow tubes so that through them the cleaning liquid can be fed to the spray nozzles 12. The supply of the Cleaning fluid to the brackets 10, 11 takes place by means of piping 13 from one end of a hose 14. The hose 14 is in one of the to this Purpose trough-shaped running rails 5, 6 are laid and according to the scaffolding movement wound onto a drum of a detergent store or from this drum unwound, the one coupling between the other end of the hose and the cleaning memory represents.
Die beiden Enden oder zumindest ein Ende der beiden Laufschienen 5, 6 sind beispielsweise so ausgeführt, daß die gesamte Reinigungsvorrichtung abgehoben und auf einen anderen, entsprechend ausgestalteten Spiegel umgesetzt werden kann. Geeignete Hilfsmittel hierzu können Seilzüge oder dergleichen sein.The two ends or at least one end of the two running rails 5, 6 are designed, for example, so that the entire cleaning device is lifted off and transferred to another, appropriately designed mirror will can. Suitable aids for this can be cables or the like.
Die in den Parabolspiegel eingesprühte Reinigungsflüssigkeit wird über eine oder mehrere gegebenenfalls verschließbare Abflußöffnung 15 wieder entfernt.The cleaning liquid sprayed into the parabolic mirror becomes removed again via one or more optionally closable drainage openings 15.
