Title (EN) AUTOMATED SOLAR COLLECTOR CLEANING DEVICE
(FR) DISPOSITIF DE NETTOYAGE AUTOMATISÉ DE COLLECTEURS SOLAIRES
Abstract:
(EN) An autonomous solar collector cleaning device includes at least one main shaft, a first driver attached to a first end of the at least one main shaft, and a second driver attached to a second end of the at least one main shaft. The first and second drivers propel the cleaning device along a surface of the solar collector. A first sensor is attached to the first driver to detect an edge of the solar collector, and a second sensor is attached to the second driver to detect the edge of the solar collector. A control circuit maintains alignment of the cleaning device with respect to the solar collector based on outputs from the first and second sensors.
(FR) Cette invention concerne un dispositif autonome de nettoyage de capteurs solaires, comprenant au moins un arbre principal, un premier dispositif d'entraînement fixé à une première extrémité dudit arbre principal, et un second dispositif d'entraînement fixé à une seconde extrémité dudit arbre principal. Les premier et second dispositifs d'entraînement propulsent le dispositif de nettoyage le long d'une surface du collecteur solaire. Un premier capteur est fixé au premier dispositif d'entraînement pour détecter un bord du collecteur solaire, et un second capteur est fixé au second dispositif d'entraînement pour détecter le bord du collecteur solaire. Un circuit de commande maintient l'alignement du dispositif de nettoyage par rapport au collecteur solaire sur la base des sorties provenant des premier et second capteurs.
