Abstract

La présente invention concerne un poteau intelligent, utilisant de nouvelles énergies renouvelables, permettant de fournir de l'énergie électrique à un équipement électrique installé sur un poteau, tel qu'un réverbère, une station de base de communication, ou une caméra de surveillance destinée un poste de garde, en utilisant la lumière du soleil et l'énergie éolienne. Le poteau intelligent est conçu de telle sorte que, lorsqu'un signal d'un capteur de détection de vitesse du vent indique une vitesse du vent inférieure à une vitesse du vent prédéterminée, un engrenage à broche se déplace vers l'avant afin de relier un moteur à un arbre de pale et par conséquent la rotation est effectuée par un vent à faible vitesse et une force d'entraînement du moteur, générant ainsi une énergie électrique prédéterminée ; et, lorsque la vitesse du vent détectée par le capteur de détection de vitesse du vent est supérieure à une vitesse du vent prédéterminée, l'engrenage à broche se déplace vers l'arrière de manière à séparer le moteur et l'arbre de pale.
