Abstract

L'invention concerne un appareil de production d'énergie photovoltaïque à suivi solaire comportant une base de support (1), un mécanisme d'inversion (6) cruciforme, un mécanisme d'oscillation (5) primaire, un mécanisme d'oscillation (4) d'inclinaison, et un plateau rectangulaire (2) portant un réseau de dispositifs de génération d'énergie solaire (21). Selon l'invention, le mécanisme d'inversion (6) cruciforme est fixé sur l'extrémité supérieure de la base de support (1) et est relié pivotant sur les deux axes au point central du plateau (2) ; le mécanisme d'oscillation (5) primaire, au moyen d'un treuil primaire (51) enroulant ou déroulant un câble est et un câble ouest reliés au bord est et au bord ouest du plateau, provoque l'oscillation est-ouest du plateau, l'extrémité supérieure du câble ouest ou du câble est étant dotée d'un poids primaire (57) et d'une poulie primaire supérieure (55), le poids primaire (57) étant utilisé pour équilibrer la différence de longueur de la partie s'étendant vers le haut des câbles est et ouest pendant l'oscillation est-ouest du plateau ; le mécanisme d'oscillation (4) d'inclinaison, au moyen d'un treuil auxiliaire (41) enroulant ou déroulant un câble sud et un câble nord reliés au bord sud et au bord nord du plateau, provoque l'oscillation d'inclinaison du plateau, l'extrémité supérieure du câble nord ou du câble sud étant dotée d'un poids auxiliaire (47) et d'une poulie supérieure auxiliaire (45), le poids auxiliaire (47) étant utilisé pour équilibrer la différence de longueur de la partie s'étendant vers le haut des câbles nord et sud pendant l'oscillation d'inclinaison du plateau. La résistance au vent est améliorée.
