Description

Invenţia se referă la instalaţiile de conversie a energiei regenerabile, şi anume la sisteme de orientare a platformei cu panouri solare după soare. The invention relates to renewable energy conversion installations, namely to systems for orienting the platform with solar panels towards the sun.

Este cunoscut mecanismul de orientare cu bare articulate şi angrenaj planetar, care include un mecanism plan articulat de tip culisor-bielă-balansier cu o excentricitate e, alcătuit dintr-un levier balansier de lungime l3, o bielă de lungime l4, un culisor şi un angrenaj planetar, ale cărui roţi dinţate sunt articulate pe levier, roata fiind solidară cu biela, în care levierul este un braţ port-satelit, care sub acţiunea unui actuator liniar determină o deplasare unghiulară, amplificată prin angrenajul planetar într-o deplasare unghiulară mărită a platformei solare în condiţiile unui gabarit minim şi a unor unghiuri de transmitere optime [1]. The orientation mechanism with articulated bars and planetary gear is known, which includes an articulated plane mechanism of the slider-connecting rod-rocker type with an eccentricity e, consisting of a rocker lever of length l3, a connecting rod of length l4, a slider and a planetary gear, whose gear wheels are articulated on the lever, the wheel being integral with the connecting rod, in which the lever is a satellite-carrying arm, which under the action of a linear actuator determines an angular displacement, amplified by the planetary gear into an increased angular displacement of the solar platform under conditions of a minimum size and optimal transmission angles [1].

Dezavantajele soluţiei constau în capacitatea portantă mică şi construcţia relativ complicată, ceea ce îi reduce fiabilitatea. The disadvantages of the solution are the low load-bearing capacity and relatively complicated construction, which reduces its reliability.

O soluţie mai apropiată este sistemul de orientare după soare, care include două motoare cu rotor rulant şi întrefier axial, destinate să acţioneze panoul cu celule fotovoltaice după cele două axe de orientare, totodată motoarele sunt alimentate cu câte o succesiune de impulsuri furnizate de o sursă de curent continuu, comandată printr-un calculator.

Sistemul de orientare a platformei cu panouri solare după soare include suportul rigid 1, reazemul central 2, dotat cu brida sferică 3, pe care prin intermediul locaşului sferic 4 este montată platforma cu panouri solare 5. Pe partea din spate a platformei cu panouri solare 5 sunt fixate reazemele sferice 6, amplasate în locaşurile sferice 7 ale ştocurilor motoarelor hidraulice 8 liniare. La capetele cilindrilor motoarelor 8 sunt executate locaşurile sferice 9, în care sunt amplasate reazemele sferice 10, fixate pe suportul 1. The system for orienting the solar panel platform to the sun includes the rigid support 1, the central support 2, equipped with the spherical bracket 3, on which the solar panel platform 5 is mounted through the spherical housing 4. On the rear side of the solar panel platform 5, spherical supports 6 are fixed, located in the spherical housings 7 of the linear hydraulic motor stocks 8. At the ends of the motor cylinders 8, spherical housings 9 are made, in which spherical supports 10 are located, fixed on the support 1.

Schema instalaţiei hidraulice cu sistemul de comandă computerizat (fig. 3) include o pompă hidraulică nereversibilă PH, un filtru F, o supapă de presiune Sp, distribuitoare hidraulice proporţionale cu centrul deschis DH1, DH2, DH3 cu dirijare electrică prin impulsuri electrice E1, E2, E3, E4, E5, E6 cu poziţiile 1, 0, 2, motor electric ME şi motoare hidraulice liniare MHL1, MHL2, MHL3. Dirijarea se efectuează de la sistemul de comandă computerizat 11. The scheme of the hydraulic installation with the computer control system (Fig. 3) includes a non-reversible hydraulic pump PH, a filter F, a pressure valve Sp, proportional hydraulic distributors with an open center DH1, DH2, DH3 with electrical control by electric pulses E1, E2, E3, E4, E5, E6 with positions 1, 0, 2, electric motor ME and linear hydraulic motors MHL1, MHL2, MHL3. Control is carried out from the computer control system 11.

Sistemul de orientare a platformei cu panouri solare după soare funcţionează în felul următor: la primirea semnalelor numerice de la sistemul de comandă computerizat 11, prin intermediul distribuitoarelor hidraulice proporţionale cu centrul deschis DH1, DH2, DH3, care posedă comandă electrică cu ajutorul impulsurilor electrice E1, E2, E3, E4, E5, E6, are loc deplasarea sertarelor distribuitoarelor hidraulice proporţionale în poziţiile 1, 0, 2, după care urmează deplasarea pistoanelor motoarelor hidraulice liniare MHL1, MHL2, MHL3 la o lungime transmisă de programator. Aceste mişcări coordonate ale pistoanelor motoarelor hidraulice liniare asigură orientarea optimă după soare a platformei cu panouri solare prin înclinarea ei în plan azimutal şi meridional. The solar panel platform orientation system operates as follows: upon receiving numerical signals from the computerized control system 11, through the open-center proportional hydraulic distributors DH1, DH2, DH3, which have electrical control using electrical pulses E1, E2, E3, E4, E5, E6, the proportional hydraulic distributor spools move to positions 1, 0, 2, followed by the movement of the pistons of the linear hydraulic motors MHL1, MHL2, MHL3 to a length transmitted by the programmer. These coordinated movements of the pistons of the linear hydraulic motors ensure the optimal orientation of the solar panel platform to the sun by tilting it in the azimuthal and meridional planes.
