Abstract

La présente invention concerne un appareil de génération d'énergie électrique photovoltaïque à suivi solaire à deux niveaux, qui se rapporte à des dispositifs de génération d'énergie électrique solaires. L'appareil est pourvu d'une base de support verticale (1), d'un mécanisme de retournement cruciforme (6), un mécanisme d'oscillation principal (5), un mécanisme d'oscillation de pas (4) et un plateau rectangulaire (2) qui porte un réseau de dispositifs de génération d'énergie électrique solaire (21) ; une base (61) du mécanisme de retournement cruciforme (6) est fixée sur l'extrémité supérieure de la base de support (1), un arbre principal (621) du mécanisme de retournement cruciforme (6) possédant un raccord articulé flottant à la base (61), et deux sièges paliers (63, 63') d'un arbre auxiliaire (622) du mécanisme de retournement cruciforme (6) étant respectivement fixés aux deux côtés du point central du plateau (2) ; le fond de la base de support (1) est fixé par-dessus un cadre en acier tridimensionnel (8) ; une poulie supérieure (45, 55) est agencée au milieu de chacun de deux bords adjacents sur le plateau (2) ; le mécanisme d'oscillation principal (5) et le mécanisme d'oscillation de pas (4) sont chacun pourvus d'un treuil (41, 51), les axes de rotation des deux treuils (41, 51) étant perpendiculaires l'un à l'autre ; chaque treuil (41, 51) enroule deux câbles (43, 43', 53, 53'), l'extrémité supérieure d'un câble (43, 53) étant raccordée à un poids par l'intermédiaire de la poulie supérieure correspondante, et l'extrémité supérieure de l'autre câble (43', 53') étant raccordée au milieu des bords de façon opposée aux poulies supérieures (45, 55) sur le plateau (2). La présente invention occupe uniquement une surface au sol minimale, et peut même être disposée sur des surfaces aquatiques telles que des étangs et des rivières.
