PendingCN119675564AImprove conversion efficiencySmall footprintPhotovoltaic supportsSolar heating energySingle plateStructural engineering
The invention discloses a side-pull folding type photovoltaic panel sliding control structure, and belongs to the technical field of photovoltaic panels. A side-pulling folding type photovoltaic panel sliding control structure comprises a main board frame, a base sleeve box is arranged below the main board frame, extension hinge frames are arranged on the two sides of the main board frame, folding panels are arranged on the inner sides of the extension hinge frames, and each extension hinge frame comprises a swing shaft and a hinge frame body. In order to solve the problems that a folding plate is of a manual unfolding structure and needs to be transversely stretched after being unfolded, the occupied area after being unfolded is large, and meanwhile, the photovoltaic conversion efficiency which can be achieved by a single plate is relatively low, two sets of folding plates can be folded above a main plate frame in a folded state; in this way, the occupied area of the whole photovoltaic panel structure can be reduced to the maximum extent, when the folding plate piece stretches, the four sets of folded edge plates are stretched and turned over, meanwhile, the butterfly plates at the two ends of each set of edge plates are turned over and unfolded outwards, and therefore the area of the whole photovoltaic panel is enlarged.
