Description

530 'H4 kring skenan 10. Den andra änden 22 är vridbart ansluten till en arm 40 som radiellt sträcker sig ut från kroppen 12. Vagnen 23 är sålunda mekaniskt kopplad till kroppen 12, skaftet 13 och motorn 14. Motom 14 kretsar vagnen 20 ett varv per 24 timmar, och fig. l visar att vagnen 20 och linsen 21 är belägna i ett axialplan till axeln 15, vilket även sträcker sig genom solen 30. 530 'H4 around the rail 10. The other end 22 is rotatably connected to an arm 40 which extends radially from the body 12. The carriage 23 is thus mechanically coupled to the body 12, the shaft 13 and the motor 14. The motor 20 orbits the carriage 20 one revolution per 24 hours, and fi g. 1 shows that the carriage 20 and the lens 21 are located in an axial plane of the shaft 15, which also extends through the sun 30.

Av fig. 1 och 2 kan man utläsa att linsens 21 lutning mot hoiisontalplanet kommer att variera i beroende av vagnens 23 momentana avstånd från axeln 15, dvs. banans 10 ovalitet och längsaxelorientering. Banan 10 kan som ett exempel ha en sådan ovalitet att för en konstant längd för armen 40, så kommer spegeln 21 att vara vertikalt riktad kl. 6 på morgonen och aftonen vid vårsolståndet och höstsolståndet, medan linsen 21 utbreder sig i noimalplanet till den infallande solstrålningen kl. 12 på dagen.Av fi g. 1 and 2 it can be read that the inclination of the lens 21 towards the horizontal plane will vary depending on the instantaneous distance of the carriage 23 from the shaft 15, i.e. the oval and longitudinal axis orientation of the track 10. The web 10 may, as an example, have such an oval that for a constant length of the arm 40, the mirror 21 will be vertically directed at 6 in the morning and evening at the spring solstice and autumn solstice, while the lens 21 extends in the nominal plane to the incident solar radiation at. 12 on the day.

Armen visas ha en längdjusteringsanordning 41 med vilken armens 40 längd kan justeras från tid till annan för att kompensera fór varierande största solhöjd och dagslängd under året. Längdjusteringsanordningen 41 kan vara programstyrd i motsvarighet till solhöjdsvariationen och dagslängdsvariationen vid orten for solfångaren.The arm is shown to have a length adjusting device 41 with which the length of the arm 40 can be adjusted from time to time to compensate for varying maximum sun height and day length during the year. The length adjustment device 41 can be program-controlled in correspondence with the sun height variation and the day length variation at the location of the solar collector.

På fig. l och 2 kan man se en energiabsorbator som exemplifieras av ett rör 91 vilket genomströmmas av en fluid. Röret 91 sträcker sig längs en bana som motsvarar banan för fokus av ljuset som passerar den fokuserade linsen 21 vid vårsolstånd och höstsolstånd, enligt exemplet ovan. Genom att variera annlängden kan fokus bibehållas längs röret 91 under andra delar av året.On fi g. 1 and 2 you can see an energy absorber exemplified by a tube 91 which is flowed through by an fl uid. The tube 91 extends along a path corresponding to the path of focus of the light passing the focused lens 21 at the spring and autumn solstices, according to the example above. By varying the length, the focus can be maintained along the tube 91 during other parts of the year.

Fluiden/vätskan som leds genom röret 91 värmes och dess värmeinnehåll kan utnyttjas på i sig känt vis.The fluid / liquid passed through the tube 91 is heated and its heat content can be utilized in a manner known per se.

Naturligtvis kan ett flertal rör placeras invid varandra för att belysas av ljuset från den optiska enheten 21.Of course, several tubes can be placed next to each other to be illuminated by the light from the optical unit 21.

Naturligtvis kan man som ett alternativ utnyttja ljuset som lämnar det optiska elementet 21 för belysningsändamål, exempelvis i det inre av byggnader, varvid ljuset vidareledes med en lämplig optisk transmissionsanordning. 1 fallet att den optiska enheten 21 primärt består av ett transmissionselement, så kan naturligtvis vagnen som bär enheten 21 också bära ett reflektorelement som avlänkar strålgången i solfångarens axíalplan genom vagnen, så att ljuset enkelt kan riktas mot det aktuella målet. 530 'H4 Fig. 3 illustrerar att det av linsen 21 eventuellt fokuserade ljuset riktas mot en första avlänkningsspegel 51, som är buren av en med kroppen 12 axelparallell arm 59 och en däremot vinkelrät ansluten arm 53 via en svânglagring 54 vid armens 53 yttre ände.Of course, the light leaving the optical element 21 can be used as an alternative for lighting purposes, for example in the interior of buildings, the light further being provided with a suitable optical transmission device. In the case that the optical unit 21 primarily consists of a transmission element, the carriage carrying the unit 21 can of course also carry a reactor element which deflects the beam path in the axial plane of the solar collector through the carriage, so that the light can be easily directed towards the target in question. 530 'H4 Fig. 3 illustrates that the light possibly focused by the lens 21 is directed towards a first deflection mirror 51, which is carried by an arm 59 parallel to the body 12 and an arm 53 connected thereto perpendicularly via a pivot bearing 54 at the outer end of the arm 53.

Lagringen 54 har en horisontell axel som är vinkelrät mot axeln ll och annen 53.The bearing 54 has a horizontal axis which is perpendicular to the axis II and other 53.

Vidare visas armen 59 bära en horisontell arm 63 som är parallell med armen 53 och som via en led 64 bär en andra spegel 61. Spegeln 61 är buren via en led 64 som är parallell med axeln 54. Speglama 51 till 54 visas ligga i ett gemensamt axialplan till axeln ll innehållande linsen 21.Furthermore, the arm 59 is shown carrying a horizontal arm 63 which is parallel to the arm 53 and which via a hinge 64 carries a second mirror 61. The mirror 61 is carried via a hinge 64 which is parallel to the shaft 54. The mirrors 51 to 54 are shown lying in a common axial plane to the axis ll containing the lens 21.

Ett L~fonnat ljusledarestycke 70 har sin ena skänkel 71 horisontellt inriktad mot ljuset som avlänkas av spegeln 61 och har sin andra skänkel 72 vertikalt orienterad och centrerad mot axeln 15, i inriktning mot en ljusledare 80, som är inriktad mot axeln 15 för att emotta ljus från ljusledaren 70. Ljusledarens 70 skänkel 72 är vridbar kring axeln 15 för att hålla skänkeln 71 riktad mot spegeln 61.A shaped light guide piece 70 has one leg 71 horizontally aligned with the light deflected by the mirror 61 and has its other leg 72 vertically oriented and centered toward the shaft 15, facing a light guide 80 facing the shaft 15 to receive light from the light guide 70. The leg 72 of the light guide 70 is rotatable about the axis 15 to keep the leg 71 directed towards the mirror 61.

Ljusledaren 80 vidareleder ljuset till önskat målområde för belysning och/eller värmning.The light guide 80 redirects the light to the desired target area for lighting and / or heating.

Fackmannen inser att uppfinningen kan modifieras pä många sätt inom omfånget för de bilagda patentkraven. Exempelvis kan linsen 21 ersättas av ett reflekterande element med eller utan brytkraft, och kan den efterföljande transmissionsanordningen anpassas i motsvarighet härtill.Those skilled in the art will appreciate that the invention may be modified in many ways within the scope of the appended claims. For example, the lens 21 can be replaced by a reflecting element with or without refractive power, and the subsequent transmission device can be adapted accordingly.

Av fig. 3 kan man utläsa att armens 59 övre änddel som är direkt ansluten till armen 53 med spegeln 51, är anordnad vertikalt törskjutbar medelst en drivmotor 47, dvs. längs axeln l 1. Arrnen 59 visas buren via två koaxiella styrningshylsor som är koaxiellt vridbart lagrade runt kroppen 12 resp. den vertikala skänkeln 72. Genom att spegelns 51 övre kantdel är ansluten till kroppen 12 via en länk 56 vars ändar är via leder 52, 55 anslutna till spegelns 51 övre kant resp. till kroppen 12, kan spegelns 51 lutníngsvinkel gentemot vertíkalen förändras genom vertikal förskjutning av annen 59. Genom att speglama 41, 61 är inbördes svängningskopplade via staget 62, och genomatt armen 59 innefattar två koaxiellt inbördes förskjutbara delar vilka bär armen 53 resp. 63, kan armen 63 bibehållas vid nivån för skänkelns 71 axel och kan ljuset som infaller vinkelrätt mot linsen 21 avlänkas via speglama 51, 61 in i ledaren 70 trots varierande solhöjd.Av fi g. 3, it can be read that the upper end part of the arm 59, which is directly connected to the arm 53 with the mirror 51, is arranged vertically rotatable by means of a drive motor 47, i.e. along the axis l 1. The armature 59 is shown caged via two coaxial guide sleeves which are coaxially rotatably mounted around the body 12 resp. the vertical leg 72. Because the upper edge part of the mirror 51 is connected to the body 12 via a link 56 whose ends are connected via joints 52, 55 to the upper edge of the mirror 51 resp. to the body 12, the angle of inclination of the mirror 51 relative to the vertical can be changed by vertically displacing another 59. Because the mirrors 41, 61 are mutually pivoted via the strut 62, and through the arm 59 comprises two coaxially mutually displaceable parts which carry the arm 53 resp. 63, the arm 63 can be maintained at the level of the axis of the leg 71 and the light incident perpendicular to the lens 21 can be deflected via the mirrors 51, 61 into the conductor 70 despite varying sun heights.
