Definitions

  • the present invention relates to an adjustable structure for parabolic reflector that will allow fixing on it the reflective sheets that constitute the parabolic surface.
  • this invention describes the components and the way of manufacturing the structure of the parabola from circular elements and elongated elements or beams, preferably of straight directrix, avoiding the intrinsic complexity of any structure that followed the parabolic curve.
  • the structure object of this invention has multiple applications, parabolic antennas, solar energy, and in general whenever it is necessary to manufacture a parabola of medium or large size.
  • parabolic structures known by the applicant are mostly reticulated structures that are very labor-intensive for their realization (artisanal), which do not allow any adjustment and regulation, and because of their large volume they increase their transport, galvanization, etc.
  • the adjustable parabolic structure proposed by the invention fully solves the above-mentioned problem, through the use of easily manufactured components and without requiring the use of labor-intensive manual procedures.
  • the structure starts in a "starting node" from which a series of elongated elements or beams of a direct guideline are split, although it can also be curved, forming a non-flat, conical or concave star depending on the type of beam used, on which a set of circular rings of different diameter are fixed by means of supports that allow to regulate the distance in the direction of the paraboloid axis between the plane of each ring and the starting node.
  • starting node from which a series of elongated elements or beams of a direct guideline are split, although it can also be curved, forming a non-flat, conical or concave star depending on the type of beam used, on which a set of circular rings of different diameter are fixed by means of supports that allow to regulate the distance in the direction of the paraboloid axis between the plane of each ring and the starting node.
  • Figure 1 shows a perspective view of the structure with the reflective sheets attached.
  • Figure 2 shows a section in the plane of the axis of the parabola, representing the parabola section (4) that the structure creates.
  • Figure 3 shows the initial starting component of the structure, "starting node”
  • Figure 4 shows two straight guide beams (3) coupled to the "starting node”.
  • Figure 5 shows two curved guide beams (3) coupled to the "starter node”.
  • Figure 6 shows the circular rings (5).
  • Figure 7 shows a ring-beam joint support (6) with its torn holes or collisions (9).
  • Figure 8 shows a clamp (7) for joining the reflective sheets with the rings.
  • Figure 9 shows the studs (8) that fix the reflective sheets to the clamps (7).
  • Figure 10 shows the couplings between the five basic components and the reflective sheet.
  • Figure 1 1 shows a perspective view of the structure object of the present invention with three straight beams. PREFERRED REALIZATION OF THE INVENTION
  • the structure starts with a tube (1) to which a variable number of cartels (2) are welded, at least 3, but preferably at least 4, in radial planes.
  • These beams are fixed metal beams of direct guideline (3), preferably UPN type, that is, with a U-shaped section, or CF, that is, with a C-shaped section, forming a star, but not flat but conical.
  • conical star of straight beams circular rings of different radius (5) are fixed based on the smaller or larger size of the reflective sheets to be used.
  • said beams may have a curved directive (10) instead of a straight guideline, forming a concave star.
  • Said curved guide beams (10) can be manufactured by stamping.
  • connection between the star and the rings is preferably carried out by means of supports (6) that are fixed on each straight beam (3) or curve (10) by means of a screw and torn hole or coliseum (9) or similar, allowing the displacement of each ring in the direction of the paraboloid axis, and therefore the adjustment and adjustment in that direction.
  • the union between the reflective sheets and the rings is proposed to be carried out by means of clamps (7) with locking screw and fixation in the ring and adjustment slot (torn hole or collision) of mounting the stud (8) of union with the reflective sheet (4).
  • the stud can be threaded allowing a second adjustment in its axial direction.
  • the fixing of the stud to the reflective sheet can be done by means of adhesive, hole and washers and nuts, etc.
  • the clamps allow its rotation around the ring or rings, being able to receive the stud of the blade at its natural angle.
