Abstract

L'invention concerne un aérogénérateur vertical présentant une structure de tour (1), des roues éoliennes et des générateurs (2). Au moins deux bases (7,7') sont disposées dans la structure de tour (1). Une roue éolienne (20) est disposée entre chacune des deux bases (7,7'). Un anémomètre est monté sur la partie supérieure des roues éoliennes (20). La roue éolienne (20) comprend un arbre rotatif (15) et au moins trois pales (5) qui sont montées sur l'arbre rotatif (15). Un générateur (2) est assemblé sous chaque roue éolienne (20). Un générateur (2), une roue éolienne (20) et deux bases (7,7') constituent une unité génératrice. La pale (5) comprend: des cadres (23), des poulies mortes (24), des câbles de hauban (28), un rouleau avant (27), un rouleau arrière (29), un électromoteur de rouleau avant (30), un électromoteur de rouleau arrière (31) et une voile à vent (36). La structure de tour (1) est montée sur une construction, chaque groupe de tiges de support (3) de la structure de tour (1) s'étendant vers le bas jusqu'à des piliers (34) de cette construction. Ce type d'aérogénérateur, dont la structure de tour est stable et difficile à faire tomber, présente un rendement énergétique élevé et une longue durée de fonctionnement. En outre, la maintenance de cet aérogénérateur peut s'effectuer facilement pendant son fonctionnement.
