Embodiment Construction

[0056] Reference is first made to Figures 1a to 1c, which illustrate a concentrated solar thermal power plant. Such a power plant 1 comprises a solar collector 2 and a reflector field 4 that concentrates solar radiation on the collector 2 . In this example the power station is a linear Fresnel type mirror, but alternatively it could also be a cylindrical parabolic type mirror, or in the case of a double curvature mirror it has a "solar tower" type Heliostats ("solar tower" type heliostats) or "dish" type parabolic mirrors.

[0057] The field 4 comprises a row of reflectors 6 arranged side by side. As will be described below, each reflector 6 comprises a mirror made of several individual mirror elements each assembled together on a structure via a frame dedicated to the invention. Furthermore, the support structure is freely mounted for rotation on the frame 8 along a preferably parallel pivot axis 10 . The rotation control can be independent or dependent and is controlled i...

Abstract

The invention relates to a reflector (6) comprising a supporting structure (18) and a mirror (16) that is preferably of non-planar form, the structure (18) being equipped with pivoting members (19) that allow the reflector to be rotated. According to the invention, the mirror (16) includes a plurality of adjacent mirror elements (16a), the reflector includes, associated with each mirror element (16a), a chassis (20) that is interposed between the structure (18) and the mirror element and that includes crosspieces (22) to which are fastened rails (24), the non-reflective surface of the mirror element (16a) being fastened to the rails (24) preferably using adhesive, the structure (18) comprises members (40) for positioning each chassis, forming points of contact (42) that define a reference bearing surface (46) for the frame (20), and each chassis (20) is mounted on the structure (18) using mechanical fastening means (36, 38) that are preferably demountable.

Description

technical field [0001] This invention relates to the field of manufacturing specular reflectors shaped to reflect and direct light. [0002] More precisely, the invention relates to the manufacture of reflectors whose mirror support structure is designed to rotate freely about at least one pivot axis to be able to orient the received light at different angles. [0003] The invention is particularly applicable in the field of solar energy, with reflectors designed to construct reflector fields for concentrated solar thermal power plants, preferably with cylindrical-parabolic type mirrors, or linear Fresnel reflectors. Background technique [0004] A reflector comprising a mirror supported by a support structure is usually manufactured using a mold on which the mirror is temporarily assembled, the mold giving the mirror its final shape. The step of positioning the mirror relative to the support structure is then performed by a relative displacement between the mold supporting...
