Description

Područje tehnike The field of technology

Tehničko rješenje odnosi se na potpornu strukturu za solarne ploče, poželjno za fotonaponske ploče, koje omogućava orijentaciju ploča oko dvije osi, takozvani dvoosni sustav praćenja. The technical solution refers to a support structure for solar panels, preferably for photovoltaic panels, which enables the orientation of the panels around two axes, the so-called two-axis tracking system.

Stanje tehnike State of the art

Za povećanje energije koja je dobivena pomoću fotonaponskih ćelija koriste se različite konstrukcije, pomične oko jedne osi, oko dvije osi ili nepomične. Različite kombinacije omogućavaju različite postotke solarnog prinosa tijekom godine. Pomicanje može biti provođeno ručno, automatski pomoću motora, dok uvijek postoji potreba za povećanjem učinkovitosti. Nepomične konstrukcije udovoljavaju zahtjevu za visokom stabilnošću i krutošću montaže solarnih ploča, posebice imajući u vidu otpor na vjetar. To increase the energy obtained by means of photovoltaic cells, different constructions are used, movable around one axis, around two axes or stationary. Different combinations enable different percentages of solar yield throughout the year. The movement can be carried out manually, automatically by means of a motor, while there is always a need to increase efficiency. Fixed constructions meet the requirement for high stability and rigidity of mounting solar panels, especially with regard to wind resistance.

Iznošenje tehničkog rješenja Presentation of the technical solution

Cilj tehničkog rješenja je potporna struktura za solarne ploče, poželjno za fotonaponske ploče, koja sadrži najmanje dva oslonca, i koje omogućava zakretanje ploča oko dvije osi, dok istovremeno nudi visoku krutost i otpornost prema vjetru. The goal of the technical solution is a support structure for solar panels, preferably for photovoltaic panels, which contains at least two supports, and which enables the rotation of the panels around two axes, while at the same time offering high rigidity and resistance to wind.

Navedeni cilj je omogućen pomoću potporne strukture za solarne ploče, poželjno za fotonaponske ploče, prema ovom tehničkom rješenju, koje sadrži najmanje dva oslonca za os rotacije solarne ploče. Princip rada potporne strukture je daje najmanje jedan oslonac osi rotacije solarne ploče podesiv po visini. The stated objective is made possible by means of a support structure for solar panels, preferably for photovoltaic panels, according to this technical solution, which contains at least two supports for the axis of rotation of the solar panel. The working principle of the support structure is that it provides at least one support for the axis of rotation of the solar panel, adjustable in height.

Posebice, princip potporne strukture prema ovom tehničkom rješenju je taj da oslonac podesiv po visini sadrži okvir koji je učvršćen u najmanje dvije točke. Oslonac osi rotacije solarne ploče je pomično postavljen na ovaj okvir. Okvir sadrži dvije okomite noge spojene pomoću donje poprečne prečke i gornje razdvajajuće prečke. Pomično postavljen oslonac sadrži dva kraka postavljena u obliku slova A. Krakovi su, na njihovom jednom kraju, spojeni sa osi rotacije solarne ploče, a na njihovom drugom kraju, krakovi su spojeni sa kolicima koja su pomično postavljena na okomitim nogama okvira. Krakovi oslonca mogu biti, zbog stabilnosti i krutosti, poželjno opremljeni sa razdvajajućom prečkom. Kolica sadrže dva pomična rukavca, koji su svaki pomično postavljeni na svakoj od okomitih nogu. Krakovi oslonca mogu, poželjno zbog stabilnosti i krutosti, biti svaki sa svojim odgovarajućim krajem spojeni na jedan pomični rukavac kolica. Pomični rukavci mogu, poželjno zbog stabilnosti i krutosti, biti međusobno povezani pomoću poprečne prečke. In particular, the principle of the support structure according to this technical solution is that the height-adjustable support contains a frame that is fixed in at least two points. The support for the rotation axis of the solar panel is movably mounted on this frame. The frame contains two vertical legs connected by a lower crossbar and an upper dividing bar. The movable support contains two arms arranged in the shape of the letter A. The arms are, at one end, connected to the axis of rotation of the solar panel, and at their other end, the arms are connected to the carriages, which are movably placed on the vertical legs of the frame. The arms of the support can be, for stability and rigidity, preferably equipped with a separating bar. The cart contains two movable arms, each of which is movably mounted on each of the vertical legs. The arms of the support can, preferably for reasons of stability and rigidity, be each connected with its respective end to one movable arm of the cart. Movable sleeves can, preferably due to stability and rigidity, be connected to each other by means of a cross bar.

Prednost je također, s obzirom na stabilnost i krutost konstrukcije, ako je oslonac podesiv po visini opremljen sa nepomičnim osloncem osi rotacije solarne ploče. Oslonac podesiv po visini može, poželjno zbog stabilnosti i krutosti, biti povezan na nepomični oslonac pomoću poprečne prečke, koja se sastoji od dva kraka postavljena u obliku slova V. Poprečna prečka može biti spojena na podesivi oslonac preko ukruta postavljenih na okviru u osnovi u obliku slova V. Ukrute mogu biti spojene na gornje razdvajajuće prečke i/ili na okomite noge i donje poprečne prečke okvira. Krakovi poprečne prečke mogu biti spojeni na jednu od ukruta okvira preko svakog od njihovih odgovarajućih krajeva. Krakovi poprečne prečke mogu, poželjno zbog stabilnosti i krutosti, biti izvedeni sa razdvajajućom prečkom. It is also an advantage, with regard to the stability and rigidity of the structure, if the height-adjustable support is equipped with a stationary support for the rotation axis of the solar panel. The height-adjustable support can, preferably for reasons of stability and rigidity, be connected to the fixed support by means of a cross-bar, which consists of two arms placed in the shape of the letter V. The cross-bar can be connected to the adjustable support via stiffeners placed on the frame in the shape of the base letters V. Stiffeners can be connected to the upper dividing bars and/or to the vertical legs and lower transverse bars of the frame. The arms of the crossbar can be connected to one of the stiffeners of the frame through each of their respective ends. The arms of the cross bar can, preferably for reasons of stability and rigidity, be made with a separating bar.

Potporna struktura prema ovom tehničkom rješenju pruža znatne prednosti kod fiksne konstrukcije solarne ploče, kao što je visoka krutost i stabilnost strukture uz odgovarajuće prednosti dvoosnog sustava praćenja, tj. mogućnosti zakretanja solarne ploče relativno prema položaju Sunca tijekom dana, kao i tijekom godišnjeg ciklusa. The support structure according to this technical solution provides considerable advantages in fixed solar panel construction, such as high rigidity and stability of the structure with the corresponding advantages of the two-axis tracking system, i.e. the ability to rotate the solar panel relative to the position of the Sun during the day, as well as during the annual cycle.

Zakretanje solarne ploče tijekom dnevnog ciklusa predviđeno je pomoću aktuatora solarne ploče spojenog na solarnu ploču, i njegove odgovarajuće potporne strukture, te na pomično postavljen oslonac osi rotacije solarne ploče. Zakretanje solarne ploče tijekom godine omogućeno je podešavanjem po visini osi rotacije solarne ploče pomoću najmanje jednog oslonca koji je podesiv po visini. Podešavanje po visini može biti omogućeno ručnim putem kao i pomoću automatskog pogona. Pogonski mehanizam može sam za sebe biti izveden pomoću bilo kojeg poznatog pogonskog mehanizma. The rotation of the solar panel during the daily cycle is provided by means of the solar panel actuator connected to the solar panel, and its corresponding support structure, and on the movable support of the rotation axis of the solar panel. The rotation of the solar panel during the year is made possible by adjusting the height of the axis of rotation of the solar panel using at least one support that is adjustable in height. Height adjustment can be enabled manually as well as with an automatic drive. The drive mechanism itself can be made using any known drive mechanism.
