Definitions

  • the invention relates to a solar collector of the kind that is seen in the preamble of the appended claim 1.
  • Solar collectors are previously known and comprise an optical unit, an apparatus to keep the optical unit directed to the sun during the daytime, and a transmission device for guiding light received by the optical unit further to a target.
  • Previously known solar collectors comprise complex devices and control systems to keep the optical unit directed to the sun during the daytime, and guide radiation received by the optical unit further to a target.
  • an object of the invention is to provide a solar collector of a simple and robust structure, and having a small sensitivity to interruption.
  • Fig. 1 schematically shows a horizontal view from above of a main part of a solar collector.
  • Fig. 2 shows a schematic section taken along line II — II in Fig. 1.
  • Fig. 3 schematically shows a transmission device as coupled to the solar collector.
  • Fig. 1 an oval horizontal guide rail 10 is shown.
  • a body 12 that via a shaft 13 is rotationally driven by a motor 14, so that the body 12 rotates around a vertical axis 15 extending through the centre of curvature 11 of the path 10.
  • a carriage 20 is shown that carries an optical unit 21 in the form of a focussing lens 21.
  • the lens 21 has (cf. Fig. 2) two spaced-apart ends 22, 23.
  • One of the ends 23 is carried by the car- riage 20 that is turnable around the rail 10.
  • the other end 22 is turnably connected to an arm 40 that extends radially out from the body 12.
  • the carriage 23 is mechani- cally coupled to the body 12, the shaft 13 and the motor 14.
  • the motor 14 revolves the carriage 20 one revolution per 24 h, and Fig. 1 shows that the carriage 20 and the lens 21 are situated in an axial plane of the axis 15, which also extends through the sun 30.
  • the inclination of the lens 21 to the horizontal plane will vary depending on the instantaneous distance of the carriage 23 from the axis 15, i.e., the ovality and longitudinal axis orientation of the path 10.
  • the path 10 may have such ovality that for a constant length of the arm 40, the mirror 21 will be vertically directed 6 a.m. and p.m. on the vernal equinox and the autumnal equinox, while the lens 21 extends in the normal plane of the incident solar radiation at 12 noon.
  • the arm is shown to have a length-adjustment device 41 by means of which the length of the arm 40 can be adjusted from time to another in order to compensate for varying maximum solar angle and length of the day during the year.
  • the length-adjustment device 41 may be program-controlled in correspondence with the variation of the solar angle and the variation of the length of the day at the locus of the solar collector.
  • FIGs. 1 and 2 an energy absorber, exemplified by a pipe 91 traversed by a fluid, can be seen.
  • the pipe 91 extends along a path corresponding to the path of the focus of the light passing the focussing lens 21 at the vernal equinox and autumnal equinox, according to the example above.
  • focus can be kept along the pipe 91 during other parts of the year.
  • the fluid/liquid fed through the pipe 91 is heated, and the heat content thereof can be utilized in a known manner, per se.
  • a plurality of pipes may be placed close by each other in order to be illuminated by the light from the optical unit 21.
  • the light that leaves the optical element 21 may be utilized for lighting purposes, for instance in the interior of buildings, the light being guided further by means of a suitable optical transmission device.
  • the carriage carrying the unit 21 may also carry a reflector element, which deflects the beam path in the axial plane of the solar collector through the carriage, so that the light easily can be directed to the target in question.
  • Fig. 3 illustrates that the light possibly focused by the lens 21 is directed to a first deflection mirror 51, which is carried by an arm 59, axially parallel to the body 12, and an arm 53 perpendicular thereto and connected via a pivot mounting 54 at the outer end of the arm 53.
  • the mounting 54 has a horizontal axis that is perpendicular to the axis 11 and the arm 53.
  • the arm 59 is shown to carry a horizontal arm 63 that is parallel to the arm 53 and that, via a joint 64, carries a second mirror 61.
  • the mirror 61 is carried via a joint 64 that is parallel to the axis 54.
  • the mirrors 51 through 54 are shown to lie in a common axial plane of the axis 11 containing the lens 21.
  • An L-shaped light-guide piece 70 has one branch 71 thereof horizontally aligned with the light deflected by the mirror 61, and has the other branch 72 thereof vertically oriented and centred to the axis 15, in alignment with a light guide 80, which is aligned with the axis 15 in order to receive light from the light guide 70.
  • the branch 72 of the light guide 70 is turnable around the axis 15 in order to keep the branch 71 directed to the mirror 61.
  • the light guide 80 guides the light further to the desired target area for illumination and/or heating.
  • the lens 21 may be replaced by a reflecting element with or without refraction power, and the following transmission device can be adapted in correspondence therewith.
  • Fig. 3 it can be understood that the upper end part of the arm 59, directly connected to the arm 53 having the mirror 51 , is arranged vertically displaceable by means of a driving motor 47, i.e., along the axis 11.
  • the arm 59 is shown carried via two coaxial guide bushings, which are coaxially turnably mounted around the body 12 and the vertical branch 72, respectively.
  • the angle of inclination of the mirror 51 in relation to the vertical can be altered by vertical displacement of the arm 59.
  • the mirrors 41, 61 are mutually pivotably coupled via the stay 62, and by the fact that the arm 59 comprises two coaxially mutu- ally displaceable parts that carry the arm 53 and 63, respectively, the arm 63 can be retained at the level of the axis of the branch 71, and the light inciding perpendicular to the lens 21 can, via the mirrors 51, 61, be deflected into the guide 70 in spite of varying solar angle.
