Abstract

La présente invention concerne un dispositif d'isolation thermique nocturne pour un chauffe-eau solaire, comprenant un cadre de montage (1). Des fentes de coulissement (6) sont formées sur les intérieurs des côtés gauche et droit du cadre de montage (1). Un engrenage C (22) est relié de façon rotative au-dessus des fentes de coulissement (6). Le côté externe de l'engrenage C (22) est relié à une extrémité d'une chaîne (14) de façon à venir en prise, et l'autre extrémité de la chaîne (14) est reliée à un engrenage B (13) de façon à venir en prise. Une tige de dégagement (18) est montée de façon coulissante à l'intérieur de chaque fente de coulissement (6). Un réservoir de stockage d'eau (2) est monté de façon fixe au-dessus du cadre de montage (1). La partie inférieure du réservoir de stockage d'eau (2) est reliée de façon amovible à une extrémité de chaque tige de chauffage d'eau (4), et l'autre extrémité de chaque tige de chauffage d'eau (4) est reliée de façon amovible à un tuyau de communication (11). Le côté droit du tuyau de communication (11) est relié de façon amovible à une pompe à eau circulante (10). Le dispositif d'isolation thermique nocturne pour un chauffe-eau solaire peut rapidement dégager de la neige sur les surfaces des tiges de chauffage d'eau, améliore l'efficacité de chauffage, et évite efficacement que des canalisations soient gelées, de façon à améliorer l'aptitude à la mise en œuvre.
