Alignment and/or tracking device for solar collectors

Abstract

The invention relates to an alignment and/or tracking device ( 1 ) for solar collectors (x), comprising a plurality of pivot axles (S) on each of which a plurality of solar collectors ( 5, 5 ′) are mounted, and a jointly acting adjustment device ( 6, 7, 8 ) which couples the pivot axles (S) to one another in such a way that the pivot axles (S) are jointly pivotable. The alignment and/or tracking device according to the invention is characterised in that the adjustment device ( 6, 7, 8 ) is coupled to each of the pivot axles (S) by at least one articulation joint (GL), in particular a universal joint.

1 . Alignment and/or tracking device for solar collectors, having:
 a plurality of pivot axles on which in each case a plurality of solar collectors are mounted, and   a jointly acting adjustment device which couples the pivot axles to one another in such a manner that the pivot axles are jointly pivotable,   wherein   the adjustment device is coupled to the pivot axles in each case via at least one articulated joint, in particular a cardanically acting articulated joint.   
     
     
         2 . Alignment and/or tracking device according to  claim 1 , wherein at least one pivot axle has at least two carrying elements, between which a connecting articulated joint, in particular a cardanically acting connecting articulated joint, is arranged. 
     
     
         3 . Alignment and/or tracking device according to  claim 1 , wherein the pivot axles are supported on support elements, wherein a support articulated joint, in particular a separable ball joint, is provided between the pivot axles and at least a few support elements. 
     
     
         4 . Alignment and/or tracking device according to  claim 1 , wherein the adjustment device has at least one pivot drive. 
     
     
         5 . Alignment and/or tracking device according to  claim 4 , wherein at least one pivot drive operates hydraulically or electromotorically. 
     
     
         6 . Alignment and/or tracking device according to  claim 4 , wherein the adjustment device has two pivot drives which are arranged at opposite ends of the adjustment device and act in opposite directions. 
     
     
         7 . Alignment and/or tracking device according to  claim 4 , wherein the adjustment device has a control device which is set up to control the pivot drives in such a manner that connecting elements of the adjustment device are always tensioned at least in operation. 
     
     
         8 . Alignment and/or tracking device according to  claim 1 , wherein the adjustment device has a plurality of adjusting lever units, wherein in each case a rod-shaped element, in particular a traction means, is provided between two adjacent adjusting lever units. 
     
     
         9 . Alignment and/or tracking device according to  claim 8 , wherein the adjusting lever units in each case have one adjusting lever which couples the adjustment device to the assigned pivot axle. 
     
     
         10 . Alignment and/or tracking device according to  claim 8 , wherein at least one adjusting lever unit has a restoring means, in particular a spring, in order to actuate the respective adjusting lever in the direction of a starting position. 
     
     
         11 . Alignment and/or tracking device according to  claim 1 , wherein the adjustment device has articulated joints, preferably ball heads, in particular in the region of a connection between adjusting lever units and rod-shaped elements. 
     
     
         12 . Alignment and/or tracking device according to  claim 1 , wherein the pivot axle extends substantially in the North-South direction.
