Description

Technical Field

[0001] The utility model relates to the field of photovoltaic solar energy, in particular to an anti-dust accumulation component. Background Art

[0002] Photovoltaic modules are the core components of photovoltaic power generation systems. Their main function is to convert solar energy into electrical energy. Photovoltaic modules are easily affected by impact and vibration during transportation. The packaging of photovoltaic modules needs to provide stable support to ensure that the modules will not move or tilt during transportation to avoid damage. Therefore, photovoltaic modules are usually packaged with edge guards during transportation. For example, C-shaped edge guards are provided at the two long vertical sides, and strip packing tape is used to fix the outer side of the edge guards on the same horizontal plane.

[0003] Anti-dust modules are a mainstream product in the photovoltaic module market. They prevent dust accumulation by optimizing the short side A of the module. However, due to the lack of A side of the anti-dust module, there are gaps between the modules when they are stacked. As a result, when using the existing edge protection to pack the anti-dust modules, the short side of the module will be squeezed and deformed by the packaging tape, which seriously affects the performance of the module.

[0004] Some existing U-shaped edge guards can be filled between two components. However, during the use of the U-shaped edge guard, the edge guard and the dust prevention component need to be placed alternately, which is not only cumbersome to operate, but also difficult to arrange neatly and easy to fall off, which is not conducive to improving work efficiency and packaging quality.

[0005] In order to overcome the above-mentioned defects of the prior art, the art is in urgent need of an anti-dust accumulation component technology for quickly and stably filling the gaps between the anti-dust accumulation components to prevent the anti-dust accumulation components from deforming during transportation, thereby improving the working efficiency of the anti-dust accumulation component packaging and the stability during transportation.

[0043] In order to overcome the above-mentioned defects of the prior art, the utility model provides an anti-dust accumulation component for quickly and stably filling the gaps between the anti-dust accumulation components to prevent the anti-dust accumulation components from being deformed during transportation, thereby improving the working efficiency of the anti-dust accumulation component packaging and the stability during transportation.

[0044] Please refer to Figure 1 to Figure 4 , Figure 1 A schematic structural diagram of a dust accumulation prevention assembly provided according to some embodiments of the utility model is shown. Figure 2A A schematic diagram of the overall structure of the edge protection provided according to some embodiments of the utility model is shown. Figure 2B A schematic diagram of a local structure of an edge protection provided according to some embodiments of the utility model is shown. Figure 3 A schematic diagram of the front structure of a battery cell provided according to some embodiments of the utility model is shown. Figure 4 A schematic diagram of the top structure of a battery cell provided according to some embodiments of the utility model is shown.

[0045] like Figure 1 , Figure 2A to Figure 2BAs shown, the dust accumulation prevention assembly includes an assembly body and at least one edge guard 11. The assembly body includes a plurality of battery cells 10, and the at least one edge guard 11 includes a fixing portion 111 and a plurality of filling portions 112. Here, the plurality of filling portions 112 are arranged on the side of the fixing portion 111 facing the assembly body to support the assembly body. The fixing portion 111 of the at least one edge guard 11 extends parallel to and across the at least three battery cells 10 along multiple ends of the third surface 103 of the at least three battery cells 10 to fix the battery cells 10.

[0046] like Figure 3-4 As shown, each of the battery cells 10 has a first surface 101 facing the adjacent battery cell 10, which is provided with a through groove 1011 for preventing dust accumulation. The battery cell 10 also has a second surface 102 parallel to the first surface 101, and the second surface 102 cooperates with the first surface 101 of the adjacent battery cell 10 to form the through groove 1011. The battery cell 10 also has a third surface 103, which is perpendicular to the first surface 101 and the second surface 102.

[0053] Preferably, a wedge-shaped structure may be further provided at the end of the filling portion 112 to guide the filling portion 112 to extend between the boss 1012 of the battery cell 10 and the second surface 102 of the adjacent battery cell 10 to fill the through-body groove 1011 .

[0054] Furthermore, the wedge-shaped structure is provided with a limiting structure facing the fixing portion 111 , which is used to cooperate with the boss 1012 to prevent the filling portion 112 from escaping from the through-body groove 1011 .

[0055] Further, the first surface 101 and / or the second surface 102 are made of glass, and the filling portion 112 is made of a buffer material to buffer the collision between the first surface 101 and the second surface 102.
