Instalaţia de conversiune a energiei valurilor (fig. 1) funcţionează în modul următor. The wave energy conversion plant (fig. 1) operates in the following way.
Sub acţiunea valurilor corpurile plutitoare 4 şi 5 efectuează mişcări de translaţie verticale alternative care se transmit sub formă de mişcări de rotaţie alternativă ale braţelor 2 şi 3. Graţie legăturii cinematice a corpurilor plutitoare 4 şi 5 cu tijele 6 şi 7, ultimelor li se comunică mişcări de translaţie verticale alternative, în urma cărora în camerele de presiune ale cilindrilor 10 şi 11 se măreşte presiunea. Aerul comprimat din camerele de presiune 10 şi 11 se transmit consecutiv în camerele de admisie ale cilindrilor 12 ai hidromotorului axial 13. Ca rezultat capetele tijelor 14 acţionează asupra flanşei înclinate 15 a planşaibei 16, comunicându-i o mişcare de precesie în jurul centrului O. În continuare această mişcare de precesie se transformă prin intermediul flanşei înclinate 17 a planşaibei 16, a corpurilor de rulare şi flanşei înclinate a arborelui 18 în mişcare de rotaţie a arborelui condus 18, care este transmisă rotorului generatorului electric 19. Under the action of the waves, the floating bodies 4 and 5 perform alternative vertical translational movements which are transmitted in the form of alternative rotational movements of the arms 2 and 3. Thanks to the kinematic connection of the floating bodies 4 and 5 with the rods 6 and 7, the latter are communicated with alternative vertical translational movements, as a result of which the pressure in the pressure chambers of the cylinders 10 and 11 increases. The compressed air from the pressure chambers 10 and 11 is transmitted consecutively to the intake chambers of the cylinders 12 of the axial hydraulic motor 13. As a result, the ends of the rods 14 act on the inclined flange 15 of the plate 16, imparting to it a precession movement around the center O. Further, this precession movement is transformed by means of the inclined flange 17 of the plate 16, the rolling bodies and the inclined flange of the shaft 18 into the rotational movement of the driven shaft 18, which is transmitted to the rotor of the electric generator 19.
Instalaţia de conversiune a energiei valurilor (fig. 2) funcţionează în modul următor. The wave energy conversion plant (fig. 2) operates in the following way.
Suplimentar la energia produsă prin transformarea mişcărilor alternative de translaţie ale corpurilor plutitoare 4 şi 5 în energie electrică prin utilizarea cilindrilor 10 şi 11 şi a hidromotorului 13, o altă parte a energiei valurilor se transformă în mişcare de rotaţie alternativă, care se transformă în mişcare de rotaţie continuă cu ajutorul dispozitivului 20 de sumare a mişcărilor de rotaţie alternative, care este transmisă rotorului generatorului electric 19. In addition to the energy produced by transforming the alternative translational movements of the floating bodies 4 and 5 into electrical energy by using the cylinders 10 and 11 and the hydromotor 13, another part of the wave energy is transformed into alternative rotational movement, which is transformed into continuous rotational movement by means of the device 20 for summing the alternative rotational movements, which is transmitted to the rotor of the electric generator 19.
Astfel soluţiile tehnice propuse asigură majorarea eficienţei de conversiune şi a productivităţii sistemului. Thus, the proposed technical solutions ensure increased conversion efficiency and system productivity.
