Problems solved by technology

[0005] Therefore, the main disadvantages of the known design of parabolic mirror support structures for forming parabolic trough collectors include in fact the impossibility of forming a longitudinally continuous mirror surface within a parabolic trough collector, because in the individual elements or parabolic trough collectors with support towers or struts formed between the segments, which protrude into the area of ​​the mirror surfaces, so that there is always a transverse band-like area in which no mirror elements or reflective surfaces can be placed
Moreover, the known lattice frame constructions entail high production costs due to the expensive metal construction and the need to provide reinforcement plates for the transmission of forces for the purpose of tracking the parabolic trough collectors

Embodiment Construction

[0025] figure 1A parabolic mirror support structure 1 is shown comprising a twisted tube 2 mounted on two support towers 3 . In this case, the torsion tube 2 is rotatably supported in roller bearings 4 provided on the support tower 3 . Support arms 15 in the form of a lattice frame structure are arranged on the twisted tube 2 on the fixing lug 5 formed in such a way as to be fixed on the side surface of the twisted tube 2 . The parabolic mirror elements 6 are fastened without spacing in the longitudinal direction of the twisted tube 2 to these support arms 15 and thus to the parabolic mirror support structure 1, preferably lying next to each other without gaps, so that the The longitudinal direction of the twisted tube produces continuous mirror surfaces 16a, 16b, respectively. Only at the apex 17 of the parabolic profile of an adjacent parabolic mirror element 6 is a continuous longitudinal slot 7 produced, through which the support element 8 of the absorber support structu...

Abstract

A parabolic trough collector includes a parabolic mirror support structure with a parabolic mirror surface applied thereto, and an absorber support structure supporting an absorber tube. The parabolic mirror support structure and the absorber support structure are mechanically fastened in a fixed position relative to one another on a torsion tube that is arranged below the parabolic mirror surface, and mounted together with the parabolic mirror surface in a fashion capable of rotation about a parabolic trough collector longitudinal rotation axis. The torsion tube is arranged such that the parabolic trough collector longitudinal rotation axis coincides with the central longitudinal axis of the torsion tube.

Description

technical field [0001] The invention relates to a parabolic trough collector comprising a parabolic mirror support structure having a parabolic mirror surface, and an absorber support structure, the parabolic mirror surface being applied to the parabolic mirror support structure, the absorber support structure supporting the absorber tube, the two support structures are mechanically fixed in a mutually fixed position on the twisted tube, the twisted tube is arranged below the surface of the parabolic mirror, and the two support structures can be together with the twisted tube The parabolic trough collectors are mounted in such a way that they rotate around the longitudinal axis of rotation. Background technique [0002] For the exploitation of solar energy solar thermal power plants are used, in which insolation is obtained in the form of a plurality of reflective parabolic troughs connected in series and / or in parallel and which reflects the insolation onto absorber lines. ...
