SUPPORT BASE FOR PHOTOVOLTAIC ELEMENTS BEING STEADY OR EXTENDABLE AND RETRACTABLE INTO A PROTECTION BOX

摘要

Novelty: support base for photovoltaic elements which are steady or extendable and retractable into a protection box is disclosed. Constitution: a base composed of plural arrays of integrated triangular constructions 53 mutually supported with profiles (21,41), photovoltaic elements fixed on the profile 30 via screws 32 propelling the profiles 34 immobilizing the photovoltaic frames from the underside. The base bears at the top a mechanism and accessories 56 forming a complex of cross members the smooth extension of which is ensured by the central wheels 67; the photovoltaic frames are fixed onto the accessories 56 via the screws 65. A specific screw 72 with clockwise and counterclockwise thread extends and contracts along with the rotating nuts 71 the complex of the cross members and the photovoltaic frames by storing them up inside the protection box 86 and, thereby, protecting them from snow, hail, sand storms, and pollutants.
