Abstract

A solar radiant energy collector system has two separate panels (1) mounted on turntables (203) that can be rotated through an arc. The rotary movement is provided by pistons (202) that move linearly with a sleeve that is forced to rotate by an angled groove with a fixed bolt (206). The piston is displaced by hydraulic fluid from a pump (215) coupled to a changeover valve (216) in a line (213) connecting both piston actuator. As one piston is displaced upwards the other piston passes fluid out.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine für großtechnischen Einsatz geeignete Sonnennachführung (Nachführung) zu erschließen.The object of the present invention is a Sun tracking suitable for large-scale use To develop (tracking).

Die vorgenannte Aufgabe wird im Prinzip dadurch gelöst, das für die Drehung der Solarmontierung das Prinzip der hydraulischen Schwenkmotoren verwendet wird.In principle, the aforementioned task is solved by the fact that for the rotation of the solar mounting the principle of hydraulic swing motors is used.

Weiterbildungen, Verbesserungen, besondere Ausführungen sind Gegenstand der Unteransprüche.Further training, improvements, special designs are Subject of the subclaims.

Die Erfindung wird anhand der Zeichnung näher erläutert.The invention is explained in more detail with reference to the drawing.

Diese zeigt in:This shows in:

Fig. 1 zwei nach dem Prinzip der hydraulischen Schwenkmotoren und nach dem Schwerkraftprinzip arbeitenden Nachführungen, die miteinander über eine Fluidleitung gekoppelt sind. Fig. 1 two on the principle of hydraulic swivel motors and on the principle of gravity working trackers, which are coupled together via a fluid line.

Die Nachführung nach Fig. 1 besteht aus einem Zylinder (204), der oben einen Absatz (212) hat. Auf diesem Absatz ist über ein Axiallager (208) eine Scheibe (203) drehbar gelagert und auf der Scheibe (203) ist eine Solarmontierung (1) befestigt. Im Zylinder (204) befindet sich ein Kolben (202), der eine gewendelte Führungsnut (205) hat und beim Auffüllen/Entleeren des Zylinders (204) mit einem Fluid axial bewegt wird und gleichzeitig wird durch die Wechselwirkung eines Bolzens (206) mit der Führungsnut (205) um die Längsachse gedreht. An der Scheibe (203) ist unten axial ein Rohr (211) befestigt, das in einen Freiraum des Kolbens (202) ein- und ausfährt und wird dabei vom Kolben (202) mit Hilfe einer Paßfeder (207) mitgedreht. The tracking according to Fig. 1 consists of a cylinder (204) having a top section (212). A disc ( 203 ) is rotatably mounted on this shoulder via an axial bearing ( 208 ) and a solar mounting ( 1 ) is attached to the disc ( 203 ). In the cylinder ( 204 ) there is a piston ( 202 ), which has a helical guide groove ( 205 ) and is moved axially when filling / emptying the cylinder ( 204 ) with a fluid and at the same time is caused by the interaction of a bolt ( 206 ) with the Guide groove ( 205 ) rotated about the longitudinal axis. A tube ( 211 ) is axially attached to the disc ( 203 ) at the bottom, which moves in and out of a free space of the piston ( 202 ) and is rotated by the piston ( 202 ) with the aid of a feather key ( 207 ).

Die Nachführung (I) steht mit der zweiten Nachführung (II) über Fluidleitung (213) in Verbindung, die den gleichen prinzipiellen Aufbau wie (I) hat. Die Wendelnuten (16) und (16′) der beiden Nachführungen haben zueinander entgegengerichtete Wendelrichtungen, und zwar entgegengerichtet deshalb, weil dann wenn ein der beiden Kolben (202), (202′) sich im Senkvorgang befindet, sich der andere gleichzeitig hebt, wobei die Drehrichtungen der beiden Kolben und dadurch Solarmontierungen übereinstimmen müssen. Die Bewegung in eine Richtung erfolgt, weil der Kolben (202) der Nachführung (I) etwas schwerer ist als der von (II), und das z. B. dadurch, daß der Kolben (202) ein zusätzliches Gewicht (209) trägt, und in andere Richtung werden beide Nachführungen mit Hilfe z. B. einer Pumpe (215) oder eines zusätzlichen Zylinders bewegt, oder auch durch mechanische Verschiebung des Kolbens (202) und/oder (202′). In die Fluidleitung (213) ist eine Senkbremse (214) eingebaut, die eine konstante Geschwindigkeit des Kolbens (202) beim Absenken gewährleistet.The tracking (I) is connected to the second tracking (II) via fluid line ( 213 ), which has the same basic structure as (I). The spiral grooves ( 16 ) and ( 16 ') of the two followers have mutually opposite spiral directions, namely in opposite directions, because when one of the two pistons ( 202 ), ( 202 ') is in the lowering process, the other lifts simultaneously, whereby the directions of rotation of the two pistons and therefore solar mounts must match. The movement in one direction occurs because the piston ( 202 ) of the tracking (I) is slightly heavier than that of (II), and the z. B. in that the piston ( 202 ) carries an additional weight ( 209 ), and in the other direction, both trackings with the help of z. B. a pump ( 215 ) or an additional cylinder, or by mechanical displacement of the piston ( 202 ) and / or ( 202 '). A lowering brake ( 214 ) is installed in the fluid line ( 213 ), which ensures a constant speed of the piston ( 202 ) when lowering.

Die Kolben von den Nachführungen (I) und (II) können miteinander nicht über hydraulische sondern über mechanische Kraftübertragung nach Art einer mechanischen Waage gekoppelt sein.The pistons from the follow-up (I) and (II) can with each other not via hydraulic but via mechanical Power transmission coupled like a mechanical scale his.

Die Nachführungen nach Fig. 1 (I) und Fig. 1 (I+II) können nicht nur für die Drehung von Solarmontierungen sondern auch als Drehvorrichtungen für andere Anwendungen verwendet werden.The trackings according to Fig. 1 (I) and Fig. 1 (I + II) can be used not only for the rotation of solar mounts but also as turning devices for other applications.
