It is lighter and easier to assemble. It comprises a) an anchoring sub-structure (10) for anchoring to the ground; b) a tracking sub-structure (20), mounted on the anchoring sub-structure (10) and such that it can rotate about an azimuth axis; c) a driving sub-structure (30) comprising two coaxial hoops (31) formed by a plurality of assembled stamped segments (33), said hoops (31) being joined by tie-rods (32); the driving sub-structure (30) being capable of elevation rotation in relation to the tracking sub-structure (20); d) a supporting sub-structure (50), in the form of a cradle, designed to support a reflective surface; and e) a modular connection sub-structure (40), manufactured with stamped elements, whereon the supporting sub-structure (50) is mounted, and fixed on the inside of the driving sub-structure (30).
摘要:
The invention relates to a structure for a cylindrical solar collector, comprising a lattice bar structure (16) with a beam or torque box (1) at the centre thereof, said structure being capable of supporting receivers (2) of any shape and continuous or discontinuous primary reflectors (17, 17') also of any shape (parabolic, parametric, etc.). The structure can also support a secondary reconcentrator. According to the invention, the torque box (1) is multi-face polyhedron or cylinder that is divided into various sections (3), each of the sections (3) in turn being formed by multiple plates (4). The surrounding triangular lattice structure (16) is formed with L-sections, all of the connections being formed with rivets or the like. The structure comprises multiple hexagonal frames (19) along the length of the torque box (1), surrounding and reinforcing the latter and multiple supports that hold the receiver above the torque box (1).

The invention relates to a prestressed solar collector module forming a support structure for solar collectors, of the type formed by a lattice bar structure including a central beam (1) essentially characterized in that: - the central beam or torque box (1) takes the form of a multi-face polyhedron or cylinder, that is divided into sections (3) each section (3) being formed by multiple bent or curved plates (4), - a surrounding triangular lattice structure (16) is provided to support the parabolic reflector (17) which structure is formed with L-shaped elements, all of the connections being formed with rivets, - and all of the structure is prestressed using a series of tension rods (13, 14, 15) which optimise the flexural behaviour of the structure and which include end anchoring points and intermediate through-points allowing the necessary curvature to be obtained and the tension to be maintained.
