Description

Technical Field

[0001] The utility model mainly relates to the technical field of solar photovoltaic panels, in particular to a foldable solar photovoltaic panel. Background Art

[0002] Solar energy is the cleanest energy source, and solar energy resources are very abundant. Solar power generation is the process of converting solar energy into electrical energy and storing it using the principle of semiconductor photoelectric conversion. With the increasingly serious environmental pollution problem and the near exhaustion of non-renewable fossil energy, solar power generation has been increasingly valued by all mankind and has been widely used. In order to obtain solar energy, photovoltaic power generation devices are usually set up outdoors, and in order to obtain more sunlight, photovoltaic power generation devices have as large a sunlight exposure area as possible to obtain more electricity.

[0003] After searching, it is found that the utility model patent with publication number CN218243450U discloses a foldable solar photovoltaic panel, including a pair of parallel bottom frames, an intermediate base frame is arranged between the middle parts of the pair of bottom frames, and the two sides of the intermediate base frame are hinged with flip side frames via hinges. After the two flip side frames are folded and flipped, the ends of the two flip side frames are butted, a first solar photovoltaic panel is fixed on the intermediate base frame, and a second solar photovoltaic panel is fixed on the surface of the flip side frame; an electric telescopic push rod is arranged between each of the flip side frames and the intermediate base frame; a protective plate is fixed on the bottom surface of the flip side frame; this patent realizes the folding of the first solar photovoltaic panel and the second solar photovoltaic panel together, and flips the protective plate to the upper surface, thereby playing a protective role to avoid heavy rain and snow, especially in some areas when hail occurs, the accumulation of snow and the impact of hail will cause damage to the photovoltaic panel.

[0004] In the above patented technical solution, the flip side frames with flipping arrangement are hingedly connected on both sides of the middle base frame through hinges, and the folding and opening between the flip side frames and the middle base frame are driven by the extension and retraction of the electric telescopic push rod. However, the above patented technical solution still has the following shortcomings in actual application:

[0005] 1. When the above patented technical solution is used, although the photovoltaic panels can be folded and opened by hinges and electric telescopic push rods, it is very inconvenient to assemble and disassemble the two photovoltaic panels by hinges. When one of the photovoltaic panels fails, the maintenance personnel need to disassemble a large number of bolts to disassemble the damaged photovoltaic panel, which brings inconvenience to the maintenance personnel and affects the maintenance efficiency of the photovoltaic panels.

[0006] 2. When the above-mentioned patented technical solution is used, since the photovoltaic panels need to be exposed to the sun for a long time, thick dust is easily accumulated on the surface of the photovoltaic panels. The accumulated dust will block the transmission of sunlight, thereby causing the power generation efficiency of the photovoltaic panels to decrease. However, the above-mentioned patented technical solution does not have dust removal measures, resulting in a decrease in the practicality of the photovoltaic panels and a low power generation efficiency.

[0007] Therefore, we provide a foldable solar photovoltaic panel to solve the defects in the above solutions. Utility Model Content
