Abstract

The rings are assembled from the interchangeable plates. The structure forms them into a precisely conical or round paraboloid surface. The bundled sunrays are spectrally divided with the aid of prisms (15), can be arranged to fall on a circular surface (16). The main part of the supporting structure can be an inflated inverted-toroidal round hollow body with a meridional curve determined by a formula based on Cartesian coordinates. The body wall can consist of overlapping interchangeable elastic sheet-sections enclosed by a three-dimensional chain with solid and flexible links.

Description

Die Erfindung betrifft einen Spiegel, der für die Bündelung der energie- oder informationstragenden Strahlung geeignet ist.The invention relates to a mirror for Bundling the energy or information-carrying Radiation is suitable.

Der Spiegel besteht aus federnden Ringen die ihrer­ seits aus den austauschbaren, reflektierenden hauch­ dünnen harten Platten zusammengesetzt und auf dem aufblasbaren Tragwerk befestigt sind.The mirror consists of resilient rings of hers partly from the interchangeable, reflective touch thin hard plates put together and on the inflatable structure are attached.

Ein SonnenspiegelA sun mirror

Die aus der Vergangenheit bekannten krummen schüs­ selartigen Spiegel sind entweder aus beschichteten Materialien wie Metall, Glas, fester Kunststoff oder aus einem poliertem Metall hergestellt worden. Die Ausführung der genauen Krümmung bei solchen Materi­ alien erfordert eine Fülle von komplizierten und kostspieligen Operationen. Aber nicht nur die Herstel­ lung selbst sondern auch das Gewicht von solchen ri­ giden Konstruktionen ist ein ökonomisches Hindernis. Der Sinn der Sonnenenergienutzung geht verloren, wenn die energetische Herstellungsausgaben den energeti­ schen Gewinn überwiegen. Dabei versteht man unter energetischen Herstellungsausgaben die sämtliche Energiemenge von der Rohmaterialgewinnung bis zum Endstadium als fertiges Erzeugnis. Unter dem energe­ tischen Gewinn versteht man die gewonnene Energie­ menge von der Installation bis zum Verschleiß der Anlage. Das gilt auch wenn keine strahlungsver­ dichtende Vorrichtungen wie der Sonnenspiegel vor­ handen, und z. B. Solarzellen direkt der Sonne ausge­ setzt sind.The crooked shots known from the past strange mirrors are either coated Materials such as metal, glass, solid plastic or made from a polished metal. The Execution of the exact curvature with such material alien requires an abundance of complicated and costly operations. But not only the manufacturers lung itself but also the weight of such ri giden constructions is an economic obstacle. The sense of using solar energy is lost, though the energetic manufacturing expenses the energeti outweigh the profit. Here one understands energetic manufacturing expenses all Amount of energy from raw material extraction to Final stage as a finished product. Under the narrow table gain is the energy gained quantity from installation to wear of the Investment. This also applies if no radiation sealing devices like the sun mirror act, and z. B. solar cells directly out of the sun sets are.

Die dargebotene Erfindung ist bestrebt einen Spiegel bereitzustellen, welcher die erwähnten Nachteile dadurch überwindet, daß er keine rigide Konstruktion ist. Wegen seiner Nachgiebigkeit den stoßartigen Belastungen gegenüber, ergibt sich eine Möglichkeit ihn als ein extrem leichtes und deshalb materialsparendes Gebilde auszuführen. Der ökonomische Effekt wird noch dadurch gesteigert daß man insbesondere den roten Anteil des Sonnenspektrums in die biochemische Energie zur Pro­ duktion von Mikroalgen umwandelt.The invention presented seeks to be a mirror to provide, which the disadvantages mentioned overcomes that it is not a rigid construction. Because of its resilience to the shock loads opposite, there is a possibility of him as one extremely light and therefore material-saving structure to execute. The economic effect is still there increased that in particular the red portion of the Sun spectrum in biochemical energy for pro production of microalgae.

Der Rest des Spektrum aber wird von der Solarzellen aufgenommen.The rest of the spectrum is from the solar cells added.

Die Sonnenstrahlung scharf gebündelt trifft optische Prismen 15 (Fig. 2) und spektral gespalten fällt auf eine mit Solarzellen bestückte Kreisscheibe 16 (Fig. 2, Fig. 3). Ein Mikroprozessor mit photovoltaischen Sensoren 18 (Fig. 2) sorgt dafür, daß die optische Achse des Parabolspiegels bleibt ständig auf die Sonne gerichtet. Die Steuersignale vom Mikroprozessor werden zu den Servomotoren 20 Zieh­ harmonika mit 19 Membrankompressor (Fig. 2) und Elektromo­ toren 23 (Fig. 3) geleitet. Über die optische Öffnung 17 und teleskopische, durch Überdruck 22 auseinander geschobene Säule 24 gelangt die Sonnenstrahlung auf die photovolta­ ische Sensoren.The solar radiation is sharply focused and hits optical prisms 15 ( FIG. 2) and spectrally split falls on a circular disk 16 equipped with solar cells ( FIG. 2, FIG. 3). A microprocessor with photovoltaic sensors 18 ( Fig. 2) ensures that the optical axis of the parabolic mirror remains directed towards the sun. The control signals from the microprocessor to the servo motors 20 pull harmonica with 19 membrane compressor ( Fig. 2) and electric motors 23 ( Fig. 3) passed. The solar radiation reaches the photovoltaic sensors via the optical opening 17 and telescopic column 24 pushed apart by excess pressure 22 .
