TROUGH COLLECTOR FOR A SOLAR POWER PLANT
First Claim
1. A trough collector for a solar power plant comprising:
- an arrangement for supplying heat originating from solar radiation, which is tiltable for alignment with respect to a position of the sun;
means for tiltable mounting of the arrangementwherein a tilt axis of the arrangement is arranged substantially in a fixed position and lies in an area of a line of gravity (39, 89) of the tiltable arrangement;
a circular-arc-shaped section above which the arrangement rests operationally for a rolling motion on stationary pedestals;
wherein a centre of curvature of the circular-arc-shaped section lies in the area of the line of gravity of the trough solar collector; and
wherein the rotation axis of the trough solar collector is arranged in a fixed position and coincides with its line of gravity.

Abstract
The invention relates to a trough collector (1) for a solar power plant, comprising a mount (34) carrying a supporting structure (30), means disposed on the supporting structure (30) for providing heat originating from incident solar radiation, and a pivot device (40) that is fixed to the supporting structure (30) and is used to pivot the supporting structure (30) with respect to the mount (34), wherein the centroidal axis (36) of the supporting structure (30) equipped with the means for providing the heat is located outside the pivot axis of the supporting structure (30), and wherein the pivot device (40) is configured such that the centroidal axis (39) of the fully equipped supporting structure (30) is located in the region of a fixed pivot axis (35). In this way, a cost-effective, and zero-backlash pivot drive for the trough collector is obtained.
