Abstract
Koncentrator solarnog zračenja sa dva spregnuta parabolična ogledala sastoji se od: velikog paraboličnog ogledala (1), koje ima otvor (7) na tjemenu (4), i malog paraboličnog ogledala (2), koje je mehanički spojeno na veliko ogledalo tako da im se osi (6) poklapaju, a žarišta (3) su im u istoj točki. Time se dobije koncentrirano sunčano zračenje kroz otvor (4) na tjemenu ako je os ogledala (6) usmjerena prema suncu. Sustav paraboličnih ogledala postavljen je na mehanizam za stalno usmjeravanje zajedničke osi ogledala (6) prema suncu. U mehanizam su ugrađena i dva ravna ogledala. Jedno ravno ogledalo (9) postavljeno je na sjecište osi paraboličnih ogledala (6) i horizontale osi vertikalnog zakretanja (8) i to pod kutem od 45° na obje osi. Drugo ogledalo (10) postavljeno je na sjecište horizontalne osi vertikalnog zakretanja (8) i vertikalne osi horizontalnog zakretanja (11) i to pod kutem od 45° na obje osi. Izlazno koncentrirano sunčevo zračenje uvijek je suosno s vertikalnom osi horizontalnog zakretanja (11), bez obzira na položaj sunca na nebu.A solar radiation concentrator with two coupled parabolic mirrors consists of: a large parabolic mirror (1) having an opening (7) at the apex (4), and a small parabolic mirror (2) which is mechanically coupled to a large mirror so that the axes (6) coincide and the focal points (3) are at the same point. This produces concentrated solar radiation through the aperture (4) on the scalp if the axis of the mirror (6) is directed towards the sun. The parabolic mirror system is mounted on a mechanism for permanently pointing the common axis of the mirror (6) towards the sun. Two flat mirrors are also built into the mechanism. One straight mirror (9) is placed at the intersection of the axis of the parabolic mirrors (6) and the horizontal axis of the vertical rotation axis (8) at an angle of 45 ° on both axes. The second mirror (10) is positioned at the intersection of the horizontal axis of vertical rotation (8) and the vertical axis of horizontal rotation (11) at an angle of 45 ° on both axes. The output of concentrated solar radiation is always co-axial with the vertical axis of horizontal rotation (11), regardless of the position of the sun in the sky.

Tehnički problem Technical problem
Sunce je s ekološkog gledišta idealan izvor energije, ali veliki nedostatak mu je što ga nema uvijek. Nema ga noću i tijekom oblačnog vremena. Problem je moguće riješiti skladištenjem te energije kada ima sunčevog zračenja i njenim korištenjem iz skladišta kada ga nema. Solarna energija je u suštini elektromagnetsko zračenje, a ono se ne može skladištiti. Potrebno je solarnu energiju pretvoriti u oblik energije pogodan za skladištenje, a poslije i u oblik pogodan za uporabu. Najprikladniji oblik energije za skladištenje je toplinska energija i to toplinska energija na višim temperaturama (temperature između 500 i 800°C). Ovakvu energiju moguće je jednostavno koristiti na tim visokim (ili nešto nižim) temperaturama (za razne vrste peći), ili na nižim temperaturama (npr. za grijanje zgrada ili pripremu tople vode), ali i pretvoriti u električnu energiju (poznata tehnologija termoelektrana). From an ecological point of view, the sun is an ideal source of energy, but its major drawback is that it is not always available. It is absent at night and during cloudy weather. The problem can be solved by storing this energy when there is solar radiation and using it from storage when there is no solar radiation. Solar energy is essentially electromagnetic radiation, and it cannot be stored. It is necessary to convert solar energy into a form of energy suitable for storage, and then into a form suitable for use. The most suitable form of energy for storage is thermal energy, and thermal energy at higher temperatures (temperatures between 500 and 800°C). This kind of energy can be easily used at these high (or slightly lower) temperatures (for various types of furnaces), or at lower temperatures (eg for heating buildings or preparing hot water), but also can be converted into electricity (known thermal power plant technology).
Za korištenje sunčeve energije na višim temperaturama upotrebljavaju se koncentratori. Koncentratori su naprave koje povećavaju gustoću solarnog zračenja, čime se stvara viša temperatura na prijemniku. Prijemnik je potrebno postaviti u žarište koncentratora, pa se javlja problem prijenosa toplinske energije od prijemnika do potrošača (skladišta). Problem je do sada rješavan u principu na jedan od sljedeća dva načina: postavljanjem potrošača zajedno s prijemnikom u žarište ili korištenjem prijenosnog fluida za prijenos topline od prijemnika do potrošača. Concentrators are used to use solar energy at higher temperatures. Concentrators are devices that increase the density of solar radiation, which creates a higher temperature at the receiver. The receiver must be placed in the focal point of the concentrator, so there is a problem of heat energy transfer from the receiver to the consumer (storage). So far, the problem has been solved in principle in one of the following two ways: by placing the consumer together with the receiver in the focal point or by using a transfer fluid to transfer heat from the receiver to the consumer.
Dosadašnja tehnička rješenja Previous technical solutions
Poznata su u principu četiri načina korištenja solarne energije s koncentratorima. To su: There are basically four ways of using solar energy with concentrators. These are:
1.) Parabolični izduženi koncentrator (žljeb) (eng. parabolic trough). To je ogledalo izrađeno od poliranog metalnog lima, oblikovano tako da u jednoj ravnini ima oblik parabole, a u drugoj ravnini je ravno i postavljeno je u smjeru istok-zapad nagnuto prema suncu tako da se sunčeve zrake cijeli dan reflektiraju od ogledala u žarišnu liniju, u koju je postavljena cijev ispunjena radnim fluidom. Radni fluid cirkulira od prijemnika do korisnika koji je ovdje najčešće generator vodene pare. Moguća temperatura radnog fluida iznosi od 150 do 350°C i predstavlja ograničenje radi relativno niske temperature. 1.) Parabolic elongated concentrator (groove) (eng. parabolic trough). It is a mirror made of polished metal sheet, shaped so that in one plane it has the shape of a parabola, and in the other plane it is flat and is placed in the east-west direction inclined towards the sun so that the sun's rays are reflected from the mirror into the focal line all day long, in which is placed a pipe filled with working fluid. The working fluid circulates from the receiver to the user, which here is usually a steam generator. The possible temperature of the working fluid is from 150 to 350°C and is a limitation due to the relatively low temperature.
2.) Koncentrator s Fresnelovim ogledalom (eng. Concentrating Fresnel reflector). To je koncentrator sličan prethodnom, s time da se umjesto izduženog paraboličnog ogledala koristi ogledalo sačinjeno od više trakastih ogledala postavljenih po paraboli tako da reflektiraju sunčevo zračenje na prijemnik (cijev) postavljen u žarišnoj liniji. Problem je isti kao pod 1.). 2.) Concentrator with Fresnel mirror (eng. Concentrating Fresnel reflector). It is a concentrator similar to the previous one, with the fact that instead of an elongated parabolic mirror, a mirror made of several strip mirrors placed along a parabola is used so that they reflect solar radiation onto a receiver (tube) placed in the focal line. The problem is the same as under 1.).
3.) Solarni toranj (eng. Solar power tower). Na vrhu tornja postavljen je prijemnik koji je spojen s korisnikom. Oko tornja postavljen je veći broj ravnih ogledala, opremljenih s mehanizmom koji ih kontinuirano pomjera, tako da stalno reflektiraju sunčevo zračenje prema prijemniku. Nedostatak ovog rješenja je u smanjenoj efikasnosti, što je posljedica različite efektivne površine ravnih ogledala tijekom dana usljed promjene kuta pod kojim dolaze sučeve zrake na ogledalo, kao i posljedica nedovoljno precizno usmjeravanih ogledala. Ovaj sustav je pogodan za skladištenje toplinske energije. 3.) Solar power tower. A receiver is placed on the top of the tower, which is connected to the user. A large number of flat mirrors are placed around the tower, equipped with a mechanism that continuously moves them, so that they constantly reflect solar radiation towards the receiver. The disadvantage of this solution is reduced efficiency, which is a consequence of the different effective surface of flat mirrors during the day due to the change in the angle at which the referee's rays reach the mirror, as well as the consequence of insufficiently precisely directed mirrors. This system is suitable for thermal energy storage.
4.) Parabolični tanjur sa Stirlingovim motorom (eng. Dish Stirling). Ogledalo je napravljeno u obliku paraboličnog tanjura. U žarištu ogledala postavljen je prijemnik, koji je spojen sa Sterlingovim motorom, a on je spojen s generatorom električne energije. Reflektor se stalno dvo-osno upravlja (zakreće), tako da sunčeve zrake stalno padaju paralelno s osi reflektora. Ovaj sustav je praktično pokazao najveću efikasnost. Ostvarena je efikasnost solarna energija - električna energija od 34%. Nedostatak ovog sustava jest nemogućnost skladištenja toplinske energije. 4.) Parabolic dish with Stirling engine (Dish Stirling). The mirror is made in the form of a parabolic dish. A receiver is placed in the focal point of the mirror, which is connected to the Sterling motor, which is connected to the electricity generator. The reflector is constantly biaxially controlled (rotated), so that the sun's rays constantly fall parallel to the axis of the reflector. This system practically showed the highest efficiency. Solar energy - electricity efficiency of 34% was achieved. The disadvantage of this system is the inability to store thermal energy.
Izlaganje suštine izuma Presentation of the essence of the invention
Primarni cilj izuma je ostvariti koncentrirano sunčevo zračenje na jednom fiksnom mjestu i s fiksnim smjerom, bez obzira na položaj sunca na nebu tijekom dana. The primary goal of the invention is to achieve concentrated solar radiation in one fixed place and with a fixed direction, regardless of the position of the sun in the sky during the day.
Sekundarni cilj izuma je ostvariti intenzitet sunčevog zračenja dovoljan da se može dobiti visoka temperatura na prijemniku, načelno viša od 750°C, i tako omogućiti njegovo korištenje kao izvora topline u termalnom postrojenju za proizvodnju električne energije ili termalnom postrojenju za drugu namjenu. The secondary goal of the invention is to achieve the intensity of solar radiation sufficient to obtain a high temperature on the receiver, in principle higher than 750°C, and thus enable its use as a heat source in a thermal plant for the production of electricity or a thermal plant for other purposes.
Daljnji cilj izuma je omogućiti prijenos koncentriranog sunčevog zračenja sustavom fiksno postavljenih ogledala ili svjetlovoda do prijemnika udaljenog oko 100m. A further goal of the invention is to enable the transmission of concentrated solar radiation through a system of fixed mirrors or optical fibers to a receiver about 100m away.
Još jedan cilj izuma je omogućiti korištenje sunčeve energije kako za vrijeme dok sunce grije (vedar dan) tako i za vrijeme dok ne grije (oblačni dan ili noć). Za ostvarenje tog cilja potrebno je realizirati efikasno skladištenje topline koristeći poznata rješenja ili eventualno neke nove izume. Another goal of the invention is to enable the use of solar energy both during the time when the sun is warming (clear day) and during the time when it is not warming (cloudy day or night). To achieve this goal, it is necessary to implement efficient heat storage using known solutions or possibly some new inventions.
Koncentrator se sastoji od dva spregnuta parabolična ogledala, jednog po promjeru većeg i jednog po promjeru manjeg, i to spregnuta tako da im se osi poklapaju, a žarište im je u istoj točki. Manje ogledalo mora imati i manju udaljenost od tjemena do žarišta. Veće ogledalo na tjemenu ima otvor (rupu) promjera nešto većeg od promjera manjeg ogledala. Ovakvim sprezanjem paraboličnih ogledala omogućeno je da se dobije koncentrirano sunčevo zračenje kroz otvor na tjemenu velikog paraboličnog ogledala uvijek kada je zajednička os ogledala usmjerena prema suncu. Tako dobiveno zračenje je paralelno međusobno i paralelno s osi ogledala. Omjer koncentracije je jednak omjeru površine većeg i površine manjeg paraboličnog ogledala. The concentrator consists of two coupled parabolic mirrors, one with a larger diameter and one with a smaller diameter, coupled so that their axes coincide, and their focal point is at the same point. A smaller mirror must also have a smaller distance from the vertex to the focal point. The larger mirror on the crown has an opening (hole) with a slightly larger diameter than the diameter of the smaller mirror. This coupling of parabolic mirrors makes it possible to obtain concentrated solar radiation through the opening at the top of the large parabolic mirror whenever the common axis of the mirror is directed towards the sun. The resulting radiation is parallel to each other and parallel to the mirror axis. The concentration ratio is equal to the ratio of the area of the larger to the area of the smaller parabolic mirror.
Koncentrator je opremljen napravom za dvoosno zakretanje, koje omogućuje praćenje sunca tijekom dana. Dvoosno zakretanje čine vertikalno zakretanje i horizontalno zakretanje. Vertikalno zakretanje obavlja se oko horizontalne osi koja je smještena iza tjemena velikog paraboličnog ogledala. Horizontalno zakretanje obavlja se oko vertikalne osi koja je asimetrično postavljena u odnosu na os ogledala. The concentrator is equipped with a device for two-axis rotation, which allows tracking the sun during the day. Two-axis rotation consists of vertical rotation and horizontal rotation. Vertical rotation is performed around a horizontal axis that is located behind the top of the large parabolic mirror. Horizontal rotation is performed around a vertical axis that is asymmetrically positioned in relation to the mirror axis.
Na sjecištu osi ogledala i osi vertikalnog zakretanja postavljeno je ravno ogledalo pod kutem od 45° u odnosu na obje osi. Ogledalo se fiksira za nosač velikog paraboličnog reflektora i zakreče se zajedno s njim. Ovo ogledalo reflektira zračenje koje izlazi iz otvora na tjemenu velikog paraboličnog ogledala, paralelno s osi vertikalnog zakretanja i to uvijek bez obzira na vertikalni zakret. At the intersection of the mirror axis and the axis of vertical rotation, a flat mirror is placed at an angle of 45° in relation to both axes. The mirror is fixed to the support of the large parabolic reflector and is rotated together with it. This mirror reflects the radiation coming out of the opening at the top of the large parabolic mirror, parallel to the axis of vertical rotation and always regardless of the vertical rotation.
Mehanizam za horizontalno zakretanje mora imati otvor (rupu) oko vertikalne osi horizontalnog zakretanja. Otvor mora biti isti ili veći od otvora na tjemenu velikog paraboličnog ogledala. Na sjecištu osi vertikalnog zakretanja i osi horizontalnog zakretanja, a pod kutom od 45°u odnosu na obje osi, postavljeno je ravno ogledalo, koje je fiksirano za pokretni dio horizontalnog zakretnog mehanizma. Ovakvo ogledalo reflektira paralelno zračenje koje dolazi od prethodnog ogledala i usmjerava ga paralelno s osi horizontalnog zakretanja, točno kroz otvor u mehanizmu horizontalnog zakretanja. The mechanism for horizontal rotation must have an opening (hole) around the vertical axis of horizontal rotation. The aperture must be the same or larger than the aperture at the vertex of the large parabolic mirror. At the intersection of the axis of vertical rotation and the axis of horizontal rotation, and at an angle of 45° in relation to both axes, a flat mirror is placed, which is fixed to the moving part of the horizontal rotation mechanism. Such a mirror reflects the parallel radiation coming from the previous mirror and directs it parallel to the axis of horizontal rotation, right through the opening in the mechanism of horizontal rotation.

Način primjene izuma Method of application of the invention
Ovaj izum omogućava da se solarna energija koristi kao toplinska energija na visokoj temperaturi. Korištenje je moguće ili trenutno ili da se skladišti u toplinski izoliranim spremnicima te se koristi kasnije kada nema sunca. Ovako dobivena energija može se koristiti za pogon peći raznih vrsta i namjena: od pripreme hrane (za kuhinje, pekare i sl.) preko toplinske prerade u industriji do proizvodnje električne struje (solarne termoelektrane). Ovaj izum može se napraviti i koristiti u raznim dimenzijama odnosno snagama od snage 1KW pa i manje do 100 KW pa i više. Također je moguće više ovakvih koncentratora spojiti na jednog korisnika jednostavnim sustavom ravnih ogledala ili svjetlovodima. Visina temperature može se mijenjati odabirom odgovarajućeg omjera koncentracije, a što se postiže izborom različitog omjera površina paraboličnih ogledala, kao i izborom odnosno različitim dizajnom prijemnika. This invention enables solar energy to be used as thermal energy at a high temperature. Use is possible either immediately or to be stored in thermally insulated containers and used later when there is no sun. The energy obtained in this way can be used to power stoves of various types and purposes: from food preparation (for kitchens, bakeries, etc.) to thermal processing in industry to the production of electricity (solar thermal power plants). This invention can be made and used in various dimensions, i.e. powers from 1 KW or less to 100 KW or more. It is also possible to connect several such concentrators to one user with a simple system of flat mirrors or optical fibers. The height of the temperature can be changed by choosing the appropriate concentration ratio, which is achieved by choosing a different ratio of the surfaces of the parabolic mirrors, as well as by choosing or different design of the receiver.
Detaljan opis jednog od načina primjene izuma Detailed description of one of the methods of application of the invention
Koncentrator se sastoji od dva parabolična ogledala: velikog paraboličnog ogledala (1) koji ima otvor (7) na tjemenu (4) i malog paraboličnog ogledala (2) koje je mehanički spojeno na veliko ogledalo i to tako da im se osi (6) poklapaju, a žarišta su im u istoj točki. Takvim međusobnim odnosom postiže se da kroz otvor na tjemenu velikog paraboličnog ogledala prolazi paralelni snop koncentriranog sunčevog zračenja paralelno sa zajedničkom osi oba ogledala, ako je ta os usmjerena prema suncu. Sustav paraboličnih ogledala postavljen je na mehanizam za stalno usmjeravanje zajedničke osi prema suncu. Mehanizam omogućava zakretanje po vertikali u zglobu vertikalnog zakretanja (13) oko horizontalne osi vertikalnog zakretanja (8) koja je iza ogledala. Također mehanizam omogućava i zakretanje po horizontali oko vertikalne osi (11) koja je asimetrična u odnosu na os paraboličnih ogledala (6), a siječe horizontalnu os vertikalnog zakretanja (8). Na sjecište osi paraboličnih ogledala (6) i horizontalne osi vertikalnog zakretanja (8) postavljeno je i za veliko parabolično ogledalo učvršćeno ravno ogledalo (9) pod kutem od 45° u odnosu na jednu i drugu os. Tako se postiže da paralelni snop koncentriranog zračenja koji prolazi kroz tjemeni otvor (7) velikog paraboličnog ogledala pada na to ogledalo (9) i reflektira se suosno s horizontalnom osi vertikalnog zakretanja (8). The concentrator consists of two parabolic mirrors: a large parabolic mirror (1) that has an opening (7) at the top (4) and a small parabolic mirror (2) that is mechanically connected to the large mirror so that their axes (6) coincide , and their foci are at the same point. With such mutual relationship, it is achieved that a parallel beam of concentrated solar radiation passes through the opening at the top of the large parabolic mirror parallel to the common axis of both mirrors, if that axis is directed towards the sun. A system of parabolic mirrors is mounted on a mechanism for constantly pointing the common axis towards the sun. The mechanism enables vertical rotation in the vertical rotation joint (13) around the horizontal axis of vertical rotation (8) which is behind the mirror. The mechanism also enables horizontal rotation around the vertical axis (11), which is asymmetrical in relation to the axis of the parabolic mirrors (6), and intersects the horizontal axis of vertical rotation (8). At the intersection of the axis of the parabolic mirrors (6) and the horizontal axis of vertical rotation (8), a flat mirror (9) fixed to the large parabolic mirror is placed at an angle of 45° in relation to one and the other axis. This is how it is achieved that a parallel beam of concentrated radiation passing through the parietal opening (7) of a large parabolic mirror falls on that mirror (9) and is reflected parallel to the horizontal axis of vertical rotation (8).
Na sjecište horizontalne osi vertikalnog zakretanja (8) i vertikalne osi horizontalnog zakretanja (11), a pod kutem od 45° u odnosu na jednu i drugu os, postavljeno je drugo ravno ogledalo (10) i fiksirano za pokretni dio horizontalne zakretne naprave (12). S ovako postavljenim ravnim ogledalima ostvareno je koncentrirano sunčevo zračenje uvijek na istom mjestu, suosno s vertikalnom osi horizontalnog zakretanja, bez obzira na vertikalni i horizontalni zakret paraboličnih ogledala, ako je os ogledala usmjerena prema suncu. Ovaj izum omogućava da se koncentrirana sunčeva energija koristi na vertikalnoj osi horizontalnog zakretanja ili da se sustavom fiksnih ogledala ili svjetlovodom može odvesti na mjesto gdje će se koristiti. At the intersection of the horizontal axis of vertical rotation (8) and the vertical axis of horizontal rotation (11), and at an angle of 45° in relation to one and the other axis, another flat mirror (10) is placed and fixed to the moving part of the horizontal rotation device (12 ). With flat mirrors placed in this way, concentrated solar radiation is always achieved in the same place, aligned with the vertical axis of horizontal rotation, regardless of the vertical and horizontal rotation of parabolic mirrors, if the axis of the mirror is directed towards the sun. This invention allows concentrated solar energy to be used on a vertical axis of horizontal rotation or to be taken to the place where it will be used by a system of fixed mirrors or a fiber optic cable.
