Abstract

The rays refracted by a path of a water lens roof show a strip of maximum light concentration which slowly changes its position. The device for collecting sunlight which has been concentrated by a water lens roof serves to keep a chain of solar cells, which supply electric current, constantly in this region of maximum light concentration. It consists essentially of a vertically and horizontally displaceable crosspiece which supports on its base the solar cells. The vertical movement is effected with the aid of two water containers serving as traction weights. According to whether they are full or empty, the crosspiece rises or falls. Two further containers are required for the horizontal displacement. Figure 2 shows the four necessary containers. The water is taken from the roof water and pumped up again when a container has reached its deepest position. Electronically controlled brakes ensure that the solar cells always receive as much light as possible. <IMAGE>

Description

Vorrichtung zum Auffangen von Sonnenlicht, das durch ein Device for collecting sunlight coming through a

Wasserlinsendach konzentriert worden ist. Duckweed roof has been concentrated.

In meiner Anmeldung vorn 23. 2. 81 wird eine Nachführvor= richtung zum Auffangen von Sonnenlicht,das durch ein Wasser= linsendach vorkonzentriert worden ist, beschrieben. Dabei werd en zur vertikalen und horizontalen Verschiebung der das Licht auffangenden Traversen Motore mit Seilwinden und zusätzliche Antriebsgewichte benutzt. In my registration before February 23, 81 a tracking device is used to collect sunlight that has been pre-concentrated by a water = lens roof is described. In doing so, the vertical and horizontal displacement of the the light-catching truss motors with winches and additional drive weights used.

Die im folgenden gegebene Beschreibung dient der Verbillig= ung der Nachführung. An Stelle der Seilwinden mit ihren Motoren und zusatzgewichten werden wasserbehälter benutzt. Die Be= wegung der Traverse kommt nun entweder dadurch zustande,daß Wasser vom wasserlinsendach aus in einen solchen Behälter strömt oder dadurch,daß er durch Abfließen von Wasser leichter gemacht worden ist.Mittels einer Pumpe wird das dem Dach entzogene Wasser von zeit zu Zeit wieder hochgepumpt. The description given below is used to reduce the cost of the Tracking. Instead of the winches with their motors and additional weights water tank used. The movement of the traverse now comes about either because Water flows from the duckweed roof into such a container or by the fact that it has been made lighter by draining off water, using a pump the water withdrawn from the roof is pumped up again from time to time.

Eine weitere Verbilligung soll durch den Ersatz der Federbrems @@en durch elektromagnetische Schanierbremsen erreicht werden.A further reduction should be achieved by replacing the spring brakes @@ en can be achieved by electromagnetic hinge brakes.

Eine solche Bremse ist im Prinzip ein Pronyscher Zaum, der mit Hilfe eines Elektromagneten gelockert wrden kann. Durch kurze, im gewünschten zeitlichen Abstand erfolgende Stromstöße wird eine schrittweiseNachführung erreicht. Die Drehbewegung der traversen erfolgt nach dem gleichen prinzip.Such a brake is in principle a Prony bridle, which with the help an electromagnet can be loosened. By short, in the desired timeframe A step-by-step tracking is achieved between current surges occurring at intervals. The rotary motion the traverses are made according to the same principle.

auch die Benutzung von winkelspiegeln zur @achkonzentration statt der Parabolrimnen trägt zur Verbilligung bei. Ein solcher Spiegel kann bei einem Reflerionevermögen von 80% zwar nur eine vierfache Konzentrationserhöhung an seiner Schein tellinie erzeugen. DAs genügt aber auch,da bei zu hoher Energie= dichte des auf die Solarzellen fallenden Lichtes deren Ober= fläche so stark erhitzt wird,daß ihr Wirkungsgrad erheblich abfällt.The use of angular mirrors for post concentration instead of parabolic trim also contributes to the reduction in price. A With a reflection capacity of 80%, such a mirror can only generate a four-fold increase in concentration on its apparent tell-line. This is sufficient, however, since if the energy density of the light falling on the solar cells is too high, their surface is heated so much that their efficiency drops considerably.

An Jedem Querträger(2) hängen über Rollen gelagert wenigstens zwei vertikale Streben6),die durch eine Querstrebe(7) mitein ander verbunden sind.zusammen mit einem vertikal beweglichen querträger (8),der über Rollen (11) von den beiden Vertikal= streben(6) getragen wird,entsteht ein in horizontaler Richtung verschiebbarer Rahmen.

Die querträger (8) von zwei sich gegenüber liegenden Rahmen tragen mehrere Traversen (9) mit ihren winkelspiegeln.J)iese verlaufen parallel zu den Längs= trägern(3). Das Gegengewicht zu ihnen und zu (8) sind die beid= en mit ihnen über die Rollen (11) verbundenen Gegentraversen (10).

A rail-like guide on (2) prevents it from falling. the Cross members (8) of two opposing frames carry several cross members (9) with their angled mirrors. These run parallel to the longitudinal beams (3). The counterbalance to them and to (8) are the two with them over the roles (11) connected counter traverses (10). These are designed as elongated containers that Absorb the ballast water.Din overvicht of water allows movement of the Traverses upwards. u little water lets them sink if the hinge brakes (12) give free movement.
