Abstract

The mirror which collects solar radiation for conversion to electrical power for desalination plant, etc., is formed by an inflatable balloon. One internal hemispherical surface has a mmirror finish, directing focussed radiation onto an internal collector; the other hemisphere is of transparent sheeting. When inflated, the balloon is held in place by anchoring cables, forming the axis of the sphere. ADVANTAGE - Structure is light, cheap and easily transported.

Description

Die Erfindung betrifft einen Ballonspiegel für Sonnen­ kraftwerke und Meerwasserentsalzungsanlagen.The invention relates to a balloon mirror for suns power plants and desalination plants.

Für die Energiegewinnung aus Sonnenlicht soll der Hohl­ spiegel möglichst groß, billig in der Herstellung und leicht sein, sowie bei mehr großen Spiegeln einfach zu transportieren und zu errichten sein. Außerdem ist ein geringer Luftwiderstand erwünscht.The hollow is intended for the generation of energy from sunlight mirror as large as possible, cheap to manufacture and be light, as well as with larger mirrors to be transported and erected. In addition, is a low air resistance desired.

Es ist bekannt, daß zur Erfüllung dieser Erfordernisse Folienkollektoren eingesetzt werden, die mittels eines Vakuums eine Spiegelfolie in einen Hohlraum hineinwöl­ ben. (Zeitschrift "Greenpeece" Jahrgang 1989, Heft 2, Seite 33).It is known to meet these needs Foil collectors are used by means of a Vacuum a mirror film into a cavity ben. ("Greenpeece" magazine, volume 1989, issue 2, Page 33).

Dabei ist allerdings ein starrer Bestandteil notwendig, über den die Spiegelfolie gespannt wird.However, a rigid component is required over which the mirror film is stretched.

Der Erfindung liegt die Aufgabe zugrunde, diesen starren Bestandteil überflüssig zu machen, wodurch die Konstruk­ tion leichter, billiger und transportabler wird. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Hohlspiegel ein aufblasbarer, zur einen Hälfte durch­ sichtiger, zur anderen Hälfte verspiegelter Ballon ist. Die mit der Erfindung erzielbaren Vorteile bestehen darin, daß der Ballonspiegel billig herzustellen, zusammenlegbar und so einfach zu transportieren, sehr leicht und durch Aufblasen schnell zu errichten ist. Durch seine eiförmige Gestalt hat er einen geringeren Luftwiderstand als ein gleichgroßer offener Spiegel. Er kann mit geringem Auf­ wand in sehr großen Dimensionen verwirklicht werden. Auch im Weltall wären riesige Ballonspiegel einsetzbar, da sie durch das völlige Fehlen starrer Konstruktionselemente beim Transport mehr wenig Gewicht und Volumen beanspruchen würden.The invention has for its object to rigid To make part superfluous, whereby the construct tion becomes lighter, cheaper and more portable. This object is achieved in that the concave mirror is an inflatable, halfway through the balloon is more visible, the other half is mirrored. The advantages achievable with the invention are that the balloon mirror cheap to manufacture, collapsible and so easy to transport, very light and through Inflation is quick to erect. Due to its egg-shaped Shape it has less drag than one same size open mirror. It can be opened with a small amount wall can be realized in very large dimensions. Also giant balloon mirrors could be used in space because they due to the complete absence of rigid construction elements require less weight and volume during transport would.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben. Es zeigenAn embodiment is shown in the drawing and is described in more detail below. Show it

Fig. 1 einen schematischen Schnitt durch den Ballonspiegel. Die schraffierte Hälfte ist verspiegelt. Das zu er­ hitzende Element ist zwischen zwei Stahltaue gespannt, welche die Achse des Ballons bilden. Fig. 1 shows a schematic section through the balloon mirror. The shaded half is mirrored. The element to be heated is stretched between two steel ropes, which form the axis of the balloon.

Fig. 2 Darstellung der Aufhängung des Ballonspiegels an zwei Masten. Vom Mittelpunkt des Achsentaues verlaufen sternförmig Stabilisierungstaue zur Außenhaut des Ballons. Eines dieser Taue kann nach unten verlängert, eine Drehung des Ballons um seine Achse verhindern. Fig. 2 representation of the suspension of the balloon mirror on two masts. Stabilizing ropes run from the center of the axis rope to the outer skin of the balloon. One of these ropes can extend downwards, preventing the balloon from rotating about its axis.
