Abstract

The invention relates to a support device for a curved mirror having support elements and a curved mirror. The objective of providing a support device for a curved mirror which is constructed in a particularly simple manner and which enables particularly low production costs is achieved by a support device in that the support device has at least one bent metal carrier profile-member, the bent carrier profile-member having in the longitudinal direction an at least similar curvature to the curved mirror and being substantially mirror-symmetrical in the longitudinal direction.

First claim

The invention claimed is:

1. Support device for a curved mirror, the support device comprising at least one bent carrier profile-member of metal, the bent carrier profile-member having in a longitudinal direction at least partially an at least similar curvature to the curved mirror and being substantially mirror-symmetrical in the longitudinal direction, wherein the at least one bent carrier profile-member is constructed as an open U-shaped carrier profile-member comprising support-elements for the curved mirror and wherein said support-elements for the curved mirror are formed by flanges of the U-shaped carrier profile-member, and wherein the at least one bent carrier profile-member is formed by means of two or more bent metal carrier profile-member portions which are connected to each other in the longitudinal direction.

2. Support device according to claim 1 , wherein lateral members of the bent U-shaped carrier profile-member form an angle of a maximum of 60° with respect to a surface normal of the curved mirror.

3. Support device according to claim 1 , wherein lateral members of the bent U-shaped carrier profile-member are orientated substantially parallel with a surface normal of the curved mirror.

4. Support device according to claim 1 , wherein the support device is constructed to support a parabolic mirror or a parabolic channeled mirror.

5. Support device according to claim 1 , wherein the bent carrier profile-member portions are deep-drawn components or a rolled profile-member comprising flanges.

6. Support device according to claim 1 , wherein a cross-section of the at least one bent carrier profile-member varies in the longitudinal direction.

7. Support device according to claim 1 , wherein the support elements for the curved mirror are provided as separate components.

8. Support device according to claim 1 , wherein two additional auxiliary struts for supporting the at least one bent carrier profile-member are provided, and the additional auxiliary struts are arranged at a side of the at least one bent carrier profile-member remote from the curved mirror to be supported.

9. Support device according to claim 1 , wherein the support elements for the curved mirror are provided by one or more at least partially flat, L-shaped, Z-shaped, U-shaped sheet metal portions or a deep-drawn component having welding or pressing-in pins, arranged on the U-shaped carrier profile-member.

10. Support device according to claim 1 , wherein the at least one bent carrier profile-member and auxiliary struts for supporting the at least one bent carrier profile-member are produced from pre-coated steel sheets which have a thickness of from 0.5 mm to 7.0 mm.

11. Support device according to claim 1 , wherein the at least one bent carrier profile-member and auxiliary struts for supporting the at least one bend carrier profile-member have been subjected to a cathode immersion lacquering operation.

12. Curved mirror for a solar power station having a plurality of support devices according to claim 1 .

13. Curved mirror according to claim 12 , wherein the mirror for a solar power station is a parabolic channeled mirror of a parabolic channeled solar power station and the plurality of support devices according to claim 1 are arranged along a longitudinal axis of the parabolic channeled mirror.
