Abstract

L'invention concerne un héliostat comprenant un réflecteur ayant une structure de panneau sandwich. Un mode de réalisation de l'invention concerne un héliostat comprenant un réflecteur ayant une structure en sandwich, l'héliostat comprenant : une partie de réflexion comprenant un panneau sandwich ayant un miroir positionné sur une surface de celui-ci ainsi qu'un matériau de remplissage formé sur une surface arrière du miroir ; une partie colonne qui supporte une surface arrière de la partie de réflexion et s'étend vers le bas pour être fixée au sol ; et une partie d'ajustement d'angle permettant d'ajuster un angle d'azimut et un angle d'altitude de la partie de réflexion. Divers modes de réalisation de l'invention permettent non seulement de réduire une épaisseur d'un verre constituant un miroir mais également une erreur d'inclinaison d'une surface de verre à l'aide d'un réflecteur ayant une structure en sandwich dans laquelle un miroir, un matériau de remplissage et une plaque sont combinés, ce qui permet de réduire le poids de l'héliostat. De plus, divers modes de réalisation de l'invention permettent de réduire la résistance d'une pression de vent appliquée à l'héliostat à l'aide d'un élément de prévention de vortex.
