Description

Invenţia se referă la domeniul surselor regenerabile de energie, şi anume la instalaţiile de conversiune a energiei valurilor. The invention relates to the field of renewable energy sources, namely to wave energy conversion installations.

Este cunoscută instalaţia, care include un ştoc, un corp plutitor cu un dispozitiv de fixare pe el, care este legat prin intermediul unei transmisii dinţate cu un multiplicator şi un generator electric, totodată pe arborele condus al multiplicatorului este montat suplimentar un volant [1]. The installation is known, which includes a stock, a floating body with a fixing device on it, which is connected by means of a gear transmission with a multiplier and an electric generator, at the same time a flywheel is additionally mounted on the driven shaft of the multiplier [1].

Dezavantajul acestei instalaţii constă în eficienţa de conversiune relativ redusă. The disadvantage of this installation is the relatively low conversion efficiency.

Cea mai apropiată soluţie este instalaţia, care include o carcasă, un corp plutitor, pe care este fixat un ştoc cu o parte cilindrică şi alta elicoidală, un fixator, care împiedică rotirea unei tije în jurul axei verticale, un cadru cu rotor amplasat în interior, fixat de carcasă, care transformă mişcarea alternativă de translaţie a ştocului în mişcare de rotaţie a rotorului şi flanşei, pe care sunt instalaţi magneţii permanenţi, care se rotesc împreună cu rotorul [2]. The closest solution is the installation, which includes a housing, a floating body, on which a stock with a cylindrical and a helical part is fixed, a fixator, which prevents the rotation of a rod around the vertical axis, a frame with a rotor located inside, fixed to the housing, which transforms the reciprocating translational movement of the stock into the rotational movement of the rotor and the flange, on which the permanent magnets are installed, which rotate together with the rotor [2].

Dezavantajul acestei instalaţii constă în eficienţa redusă de conversiune a energiei valurilor. The disadvantage of this installation is the low efficiency of wave energy conversion.

Problema pe care o rezolvă invenţia constă în creşterea eficienţei de conversiune şi a productivităţii instalaţiei. The problem that the invention solves consists in increasing the conversion efficiency and productivity of the installation.

Instalaţia de conversiune a energiei valurilor, conform invenţiei, înlătură dezavantajele menţionate mai sus prin aceea că include o carcasă, în interiorul căreia sunt amplasaţi vertical cel puţin doi arbori, un capăt al cărora este amplasat, cu posibilitatea rotirii, pe centrul unor discuri inferioare, fixate pe partea de jos a carcasei, iar celălalt capăt al lor este unit cinematic prin intermediul unei transmisii dinţate cu un multiplicator şi un generator electric, fixate pe partea de sus a carcasei, totodată pe partea de sus a arborilor prin intermediul unor cuplaje unisens şi bile sunt unite nişte discuri superioare, pe care sunt fixate nişte corpuri plutitoare, şi care comunică cu discurile inferioare prin intermediul unor bare unite prin legături articulate, amplasate uniform pe partea exterioară a discurilor inferioare şi superioare, totodată barele, care leagă primul disc inferior cu primul superior, sunt amplasate înclinat spre dreapta sub un unghi α, iar barele, care leagă al doilea disc inferior cu al doilea superior, sunt amplasate înclinat spre stânga sub acelaşi unghi α. The wave energy conversion installation, according to the invention, eliminates the above-mentioned disadvantages by including a housing, inside which at least two shafts are vertically placed, one end of which is placed, with the possibility of rotation, on the center of lower disks, fixed on the bottom of the housing, and their other end is kinematically connected by means of a gear transmission with a multiplier and an electric generator, fixed on the top of the housing, at the same time on the top of the shafts by means of one-way couplings and balls are connected some upper disks, on which some floating bodies are fixed, and which communicate with the lower disks by means of bars joined by articulated connections, uniformly placed on the outside of the lower and upper disks, at the same time the bars, which connect the first lower disk with the first upper, are placed inclined to the right at an angle α, and the bars, which connect the second lower disk with the second upper, are placed inclined to the left at the same angle α.

- fig. 1, vederea generală a instalaţiei de conversiune a energiei valurilor; - Fig. 1, general view of the wave energy conversion installation;

- fig. 2, secţiunea I din fig. 1. - fig. 2, section I of fig. 1.

Instalaţia de conversiune a energiei valurilor include o carcasă 17, în interiorul căreia sunt amplasaţi vertical cel puţin doi arbori 11 şi 12, un capăt al cărora este amplasat, cu posibilitatea rotirii, pe centrul unor discuri inferioare 9 şi 10, fixate pe partea de jos a carcasei 17, iar celălalt capăt al lor este unit cinematic prin intermediul unei transmisii dinţate 16 cu un multiplicator 18 şi un generator electric 19, fixate pe partea de sus a carcasei 17. Totodată pe partea de sus a arborilor 11 şi 12 prin intermediul unor cuplaje unisens 13, 14 şi bile 15 sunt unite nişte discuri superioare 3 şi 4, pe care sunt fixate nişte corpuri plutitoare 1 şi 2, şi care comunică cu discurile inferioare 9 şi 10 prin intermediul unor bare 5 şi 6 unite articulat prin legăturile 7 şi 8, amplasate uniform pe partea exterioară a discurilor inferioare 9 şi 10 şi superioare 3 şi 4, totodată barele 5 sunt amplasate înclinat spre dreapta sub un unghi α, iar barele 6 sunt amplasate înclinat spre stânga sub acelaşi unghi α. The wave energy conversion installation includes a housing 17, inside which are vertically placed at least two shafts 11 and 12, one end of which is placed, with the possibility of rotation, on the center of lower disks 9 and 10, fixed on the bottom of the housing 17, and their other end is kinematically connected by means of a gear transmission 16 with a multiplier 18 and an electric generator 19, fixed on the top of the housing 17. At the same time, on the top of the shafts 11 and 12, by means of one-way couplings 13, 14 and balls 15, some upper disks 3 and 4 are connected, on which some floating bodies 1 and 2 are fixed, and which communicate with the lower disks 9 and 10 by means of bars 5 and 6 articulatedly connected by links 7 and 8, uniformly placed on the outer side of the disks. lower 9 and 10 and upper 3 and 4, at the same time bars 5 are placed inclined to the right at an angle α, and bars 6 are placed inclined to the left at the same angle α.

Instalaţia de conversiune a energiei valurilor funcţionează în modul următor. The wave energy conversion plant operates in the following way.

Sub acţiunea valurilor corpurile flotante 1 şi 2 vor efectua mişcări verticale de translaţie alternative, care ulterior sunt transmise discurilor superioare 3 şi 4. Datorită faptului că barele 5 şi 6, legate articulat cu discurile superioare 3 şi 4 şi cele inferioare 9 şi 10, sunt rigide, la mişcarea discurilor superioare 3 şi 4 pe verticală, barele îşi vor modifica unghiul de înclinare α faţă de discurile inferioare fixe 9 şi 10, astfel antrenând în mişcare de rotaţie alternativă discurile superioare 3 şi 4. Mişcarea de rotaţie a discului superior 3 într-o direcţie va fi transmisă prin intermediul cuplajului unisens 13 bilelor 15 ale arborelui 11 şi mai departe prin transmisia dinţată 16 la multiplicatorul 18 şi generatorul electric 19. Datorită înclinării barelor 5 şi 6 în direcţii diferite mişcările de rotaţie ale discurilor superioare 3 şi 4 vor fi transmise în direcţii diferite transmisiei dinţate 16 prin intermediul cuplajelor unisens 13 şi 14, care se transformă într-o mişcare de rotaţie într-o singură direcţie a arborelui conducător al multiplicatorului 18. Under the action of the waves, the floating bodies 1 and 2 will perform alternative vertical translational movements, which are subsequently transmitted to the upper discs 3 and 4. Due to the fact that the bars 5 and 6, articulated with the upper discs 3 and 4 and the lower ones 9 and 10, are rigid, when the upper discs 3 and 4 move vertically, the bars will change their angle of inclination α with respect to the fixed lower discs 9 and 10, thus driving the upper discs 3 and 4 into alternative rotational movement. The rotational movement of the upper disc 3 in one direction will be transmitted through the one-way coupling 13 to the balls 15 of the shaft 11 and further through the gear transmission 16 to the multiplier 18 and the electric generator 19. Due to the inclination of the bars 5 and 6 in different directions, the rotational movements of the upper discs 3 and 4 will be transmitted in different directions of the gear transmission 16 by means of the one-way couplings 13 and 14, which are transformed into a rotational movement in one direction of the driving shaft of the multiplier 18.

Astfel soluţia tehnică propusă asigură majorarea eficienţei de conversiune şi a productivităţii instalaţiei. Thus, the proposed technical solution ensures increased conversion efficiency and plant productivity.
