Problems solved by technology
[0019] As an alternative to the biconvex structure, it is also possible to use a structure in which the transparent membrane is replaced by a fixed (transparent) plate oriented perpendicular to the incident sunlight, which has the advantage that virtually no The solar radiation is reflected, the disadvantage of which is the increased cost of the trough collector, the advantages when using membranes (lightweight construction also allows a more favorable structure of the collector frame, etc.) are lost again at least to some extent
[0020] In addition, those skilled in the art can determine that the disclosed embodiment is also a biconvex or lenticular structure, which actually still has a considerable height, because its focal line area is located inside the pressure sensor, so the energy gathering The rather small radius of curvature of the collector results in a rather large pressure sensor volume for a trough collector with a width of 5 or 10m

Embodiment Construction
[0038] figure 1 A schematic diagram showing a trough collector 1 according to the invention, with a supporting structure 2 consisting of a rectangular frame 3 mounted on a rotating device 4 which in turn is mounted on a suitable supporting device 5 . The swivel device 4 allows the alignment of the trough collector 1 according to the corresponding sun position. The rectangular frame 3 is preferably made of concrete, which is advantageous on site, that is to say simplifies production at the construction site.
[0039] The figure also shows the pressure sensor 10 at operating pressure, ie in the inflated state, having a cushion-like shape indicated by the auxiliary line 11 . The length of such a trough collector 1 may exceed 250 m and the width may exceed 10 m. The height of the pressure sensor 10 depends on the width, but in any case is smaller than this width.
[0040] The heat-absorbing tube 12 is heated by reflected solar radiation; said concentrator is located in the pres...

Abstract
A trough collector (1) for a solar power plant, comprising a pressure sensor (25), containing a heat-absorbing tube (42) for a heat-carrying fluid, and also containing an auxiliary collector energy device. Thus, the height of the pressure sensor (25) can be reduced, thereby eliminating the need to strengthen the pressure sensor (25) in the form of a frame structure, which would otherwise be required.
Description
technical field [0001] The invention relates to a trough heat collector used for a solar power generation device. Background technique [0002] For some time now, solar thermal power plants have been able to produce electricity on an industrial scale at a price comparable to that of photovoltaics, which is close to that of conventionally produced electricity, which is common today. [0003] In solar thermal power plants, the sun's radiation is reflected by means of concentrators, passed through collectors and focused in a directed manner where high temperatures are generated. The accumulated thermal energy can be taken away and used to run a heat engine, such as a turbine, which in turn drives a generator to generate electricity. [0004] Currently used solar thermal power plants include three basic forms: dish / Stella (isothermal and constant volume) system, solar tower power generation device system and parabolic trough system. [0005] The parabolic trough power plant ha...
