Definitions

  • the object of the present invention is a connecting piece specially designed to connect two adjacent cylindrical parabolic solar modules through their torsion boxes.
  • a generation system of this type is fundamentally based on a conventional thermodynamic cycle where the heating of the fluid is carried out by means of a solar collector formed by a set of parabolic trough modules.
  • Each cylindrical-parabolic module comprises a specular surface in the form of a cylindrical sector of parabolic section supported on a support structure, and a conduit located on the longitudinal line that constitutes the focus of the cylindrical-parabolic specular surface.
  • the module can rotate relative to an axis parallel to said longitudinal line, so that, by properly controlling the angle of rotation, sunlight can be reflected on the duct throughout the day.
  • an actuator formed by an electric motor connected to a hydraulic system which, in turn, acts on the central module or modules of the collector. Consequently, it is necessary to transmit that torque along the collector so that all the modules that form it are oriented in solidarity with each other. Therefore, the intermediate parts that link some modules with others are specially designed, taking into account both their function and the configuration of the modules to be connected.
  • One type of known modules are those whose support structure comprises a so-called "torsion box", which serves to transmit the torsional stresses generated during the orientation process along the row of modules that form the collector.
  • a torsion box consists essentially of a quadrangular prism-shaped structure formed by four longitudinal bars joined by means of multiple perpendicular and / or inclined transverse bars.
  • the known module called Eurotrough comprises a torsion box of this type, as described in "Eurotrough - Parabolic Trough Collector Developed for Cost Efficient Solar Power Generation", by M. Geyer et al, 11 th Symposium on Concentrating Solar Power and Chemical Energy Technologies, September 4-6, 2002, Zurich.
  • This document also describes a known joint piece, which is attached to the present application as Fig. 1.
  • Fig. 2 shows another type of joint piece known in the art. Both pieces of union are mainly formed by two parallel plates connected by a union cylindrical which constitutes the axis of rotation of the collector, each plate being configured for connection to the four corners of the torsion box of one of the adjacent modules.
  • each collector rests on a set of pylons and rotates, supported on the pylons, around an axis that passes through the cylindrical joints of the connecting pieces.
  • a collector can comprise 12 or more modules, and that the size of the joining pieces is in the order of several hundred kg.
  • the connecting piece of the present invention solves the above drawbacks thanks to a new design based on a structure that is only connectable to two opposite corners of the torsion box of an adjacent first module and two opposite corners not corresponding to the torsion box of a second adjacent module.
  • the plates are essentially boomerang shaped, the joint being located at the angle formed by its arms and comprising a pair of fixing means at the ends of the arms.
  • the plates are essentially triangular in shape, in which case the rotating union and the pair of fixing means are located on two edges of the triangle. In any of these cases, the edges can have smooth and rounded shapes to avoid stress concentration points when the piece is in load.
  • the connecting piece of the invention is preferably metal, and more preferably steel.
  • the fixing means can be any provided that they allow an adequate fixation of the connecting piece to the respective torsion boxes, although preferably these are suitable holes for bolts, pins or screws.
  • Figs. 1 and 2 show two joining pieces according to the prior art.
  • Fig. 3 shows an example of a connecting piece according to the present invention.
  • Fig. 4 shows the connecting piece of Fig. 3 attached to a solar module with a torsion box.
  • Fig. 1 shows the connecting piece according to the prior art described in the "Eurotrough” mentioned above
  • Fig. 2 shows another known connecting piece. It is observed how both pieces comprise a structure configured for simultaneous connection to the four corners of the torsion box (11) of the two adjacent solar modules (10) parabolic troughs. That is, the assembly of these connecting pieces requires the attachment of eight points to the corresponding torsion boxes.
  • connection piece (1) of this type already connected to the torsion box (11) of a module (10) can be seen in Fig. 4. It is observed how a first plate (2a) is connected to a pair of diametrically opposite corners of the torsion box (11) of the module (10) represented, while that the second plate (2b) is prepared for connection only to the pair of diametrically opposite and non-corresponding corners of the torsion box (1 1) of a second module not shown in Fig. 4. The final result is shown in Fig. 5, where a row of modules (10) joined by a plurality of connecting pieces (1) of the present invention is shown.

Abstract

La présente invention concerne un raccord spécialement conçu pour connecter deux modules solaires cylindro-paraboliques adjacents par leurs caissons de torsion. Il comprend une structure qui peut être raccordée uniquement au niveau de deux coins opposés du caisson de torsion (11) d'un premier module (10) adjacent et au niveau de deux coins opposés non correspondants du caisson de torsion (11) d'un second module (10) adjacent.
