Definitions

  • the present invention relates to a solar concentrator.
  • Background art Solar concentrators are currently known which have a structure composed of a frame that supports an orientable lattice-like steel structure, which is adapted to support the concentrator mirror and is motorized in order to allow its orientation.
  • Another currently known structure for concentrators has a motorized torsion tube to which preformed steel ribs are connected which are sometimes mutually connected by transverse stringers.
  • Such ribs are notoriously heavy and therefore onerous to transport and assemble.
  • the aim of the present invention is to provide a solar concentrator, particularly of the type with a composite cylindrical-parabolic mirror, that can be installed more easily and in shorter times than currently known structures.
  • an object of the invention is to propose a concentrator that is lighter than currently known structures.
  • Another object of the invention is to propose a solar concentrator that is simple and easy to use and can be manufactured and installed with relatively low costs.
  • a solar concentrator particularly of the type with a composite cylindrical-parabolic mirror, which comprises supporting towers that support a torsion tube that can be rotated axially by means of motors, characterized in that it comprises ribs which are fixed transversely to said tube, said composite mirror being composed of reflective panels which comprise a mirror-finished plate that is supported by a base for supporting and fixing to said ribs, said base and said ribs being made of composite materials and having substantially the same thermal expansion coefficient.
  • Figure l is a view of a solar concentrator according to the invention.
  • Figure 2 is a rear view of a mirror-finished panel of the solar concentrator according to the invention
  • Figure 3 is a partially sectional enlarged-scale view of a detail of the solar concentrator according to the invention
  • Figure 4 is an exploded perspective view of a rib of the solar concentrator according to the invention.
  • Figures 5 and 6 are perspective views of a detail, respectively in the exploded and assembled condition, of the solar concentrator according to the invention.
  • the reference numeral 10 generally designates a solar concentrator, particularly of the type with a composite cylindrical-parabolic mirror 11, which comprises supporting towers 12 which support a torsion tube 13, which can be rotated axially by means of motors.
  • a solar concentrator 10 according to the invention has a particularity in that it comprises ribs 14, which are fixed transversely to the torsion tube 13, the composite mirror 11 being composed of reflective panels 15, which comprise a thin mirror-finished plate 16 which is supported by a base 17 for support and fixing to the ribs 14, the base 17 and the ribs 14 being made of composite materials so as to have substantially the same thermal expansion coefficient.
  • the base 17 and the ribs 14 are made of a material known commercially as SMC, from the acronym of the English expression "sheet molding compound", i.e., a thermosetting composite material obtained by hot pressing of a stratified arrangement of sheets of polyester resin reinforced with glass fibers with the addition of mineral fillers and catalyst.
  • sheet molding compound i.e., a thermosetting composite material obtained by hot pressing of a stratified arrangement of sheets of polyester resin reinforced with glass fibers with the addition of mineral fillers and catalyst.
  • the ribs 14 are conveniently composed of two complementary half- ribs 18, which have corresponding seats 19 shaped so as to surround, in cooperation, the torsion tube 13.
  • the ribs 14 are further provided with brackets 20 for their mutual fixing, for example by bolting.
  • the ribs 14 are preferably provided, at the seats 19, with means for locking to the torsion tube 13, such as for example pins 21, which are adapted to enter corresponding holes 22 provided in the torsion tube 13.
  • the reflective panels 15 are conveniently connected in a bridge-like arrangement between two successive ribs 14a and 14b of the ribs 14, cooperating with them so as to give strength to the concentrator 10 that they compose.
  • the bases 17 bolted to the ribs 14 in fact allow to provide a rigid connection between the ribs and the bases, cooperating to provide a concentrator 10 which is mainly made of SMC, except for the components of the bolted connections.
  • the concentrator 10 according to the invention has a lower weight than an equivalent structure of the currently known type, while ensuring that it has considerable structural stiffness and strength.
  • reaction brackets 23 are conveniently welded, in diametrically opposite positions, to the torsion tube
  • the half-ribs 18 conveniently have a cross-section provided with concavities and convexities that are adapted to give them stiffness without increasing their weight.
  • the invention achieves the intended aim and objects, providing a solar concentrator, particularly of the type with a composite cylindrical-parabolic mirror, which can be installed more easily and in shorter times than currently known structures.
  • the ribs and the panels mainly made of SMC, are in fact lighter than currently known steel ribs and are therefore easier to handle rapidly and with a reduced use of labor, further to the advantage of installation costs.
  • the ribs are oriented on the torsion tube by coupling the pins thereon, without requiring any further adjustment, to the full advantage of simplicity and speed in assembly.
  • a solar concentrator according to the invention is further easier and simpler to use than currently known structures and further can be produced with relatively low costs.
