Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel structures, in particular to a photovoltaic panel structure capable of preventing light pollution. Background Art

[0002] Photovoltaic panels, also known as solar panels, are devices that use solar energy to convert into electrical energy. The working principle of photovoltaic panels is based on the photovoltaic effect, that is, under solar radiation, solar cells absorb photons and convert them into electrons, which form current through the circuit.

[0003] Photovoltaic panels are composed of glass sheets, EVA sheets, solar cells, TPT backsheets, and aluminum alloy frames. When the photovoltaic panel assembly is used for a long time, the top glass sheet may break due to impact, which can easily cause stains to accumulate in the cracks. These stains can increase the internal resistance of the solar cells and create risks such as short circuits.

[0004] In the existing technology, when the glass in the photovoltaic panel group is broken, it is necessary to report the problem to the manufacturer, and the manufacturer will then maintain and replace the photovoltaic panel, which will affect the normal use of the photovoltaic panel. At the same time, when replacing the glass, the sealing strip adheres to the top of the glass and is difficult to remove, which increases the speed of replacing the glass. At the same time, when the photovoltaic is in use, it may cause light pollution due to the refraction of sunlight. Utility Model Content

[0030] Please refer to Figure 3 and Figure 4 ,the fixing mechanism 7 is installed at equal intervals outside the frame 6. The fixing mechanism 7 includes a bolt 71. The bolt 71 can fasten the back plate 1 and the frame 6 in cooperation with the first nut 72 and the second nut 74. A gasket 711 is sleeved inside the bolt 71. The gasket 711 is located between the bolt 71 and the first nut 72. The gasket 711 can increase the fastening performance between the bolt 71 and the second nut 74.

[0031] The external thread of the bolt 71 is connected with the first nut 72. The first nut 72 is connected through the frame 6. One end of the bolt 71 away from the first nut 72 is threadedly connected with the second nut 74. The first nut 72 and the second nut 74 are respectively welded inside the frame 6 and the back plate 1. The welding point method improves the processing speed of the second nut 74. The second nut 74 is connected through the back plate 1. A disc 73 is sleeved outside the bolt 71. The disc 73 can drive the long arm 81 for transmission.

[0032] The degumming mechanism 8 is installed at equal intervals inside the frame 6. The degumming mechanism 8 includes a long arm 81.
