Abstract
Description
Technical Field
[0001] This utility model relates to the field of machinery, and in particular to a waterproof frame for an integrated photovoltaic module. Background Technology
[0002] Waterproofing for BIPV (Building Integrated Photovoltaics) power plants remains a persistent challenge for the industry. While measures such as installing drainage channels and applying sealant exist, these methods do not fundamentally address the waterproofing requirements of photovoltaic power plants. Utility Model Content
[0003] In view of the problems existing in the prior art, this utility model provides a waterproof frame structure for integrated photovoltaic modules to solve the problems of at least one of the above-mentioned technologies.
[0004] The technical solution of this utility model is: a waterproof frame for an integrated photovoltaic module, comprising multiple photovoltaic modules, characterized in that each photovoltaic module has a left frame on the left side and a right frame on the right side, the outer contours of the left frame and the right frame are both E-shaped, the upper end of the left frame has a left receiving groove for accommodating the edge of the photovoltaic module, the top of the left frame has an extension end, the end of the extension end has an L-shaped flap, and the end of the L-shaped flap has an inwardly bent buckle;
[0005] The upper end of the right frame is provided with a right receiving groove for accommodating the edge of the photovoltaic module. There is a gap between the top edge of the right receiving groove and the top of the photovoltaic module, and the top edge of the right receiving groove is provided with an opening. The edge of the opening is provided with a flange, which is engaged with the buckle. The top length of the right frame is less than the length of the extension end, and the gap matches the extension end.
[0006] This invention features a sophisticated L-shaped flap as a water-guiding structure, effectively guiding water flow under rain impacts of varying angles and intensities. This reduces direct contact between water and photovoltaic modules, allowing for seamless integration with existing modules. Installation is simple, and maintenance costs are low. Its widespread adoption will significantly enhance the waterproofing capabilities of photovoltaic power plants, reducing maintenance costs and power generation losses caused by waterproofing issues. This is of great importance for promoting the sustainable development of photovoltaic power plants.
[0007] More preferably, a left support column is provided below the left receiving groove, the top of the left support column is fixed to the left receiving groove, and the bottom of the left support column is fixed to the bottom of the left frame.
[0008] A right support column is provided below the right receiving groove. The top of the right support column is fixed to the right receiving groove, and the bottom of the right support column is fixed to the bottom of the right side frame.
[0009] This invention improves the stability of the frame by adding support columns on both sides.
[0010] Further preferably, a rectangular channel is provided between the left support column and the side plate of the left frame, and another rectangular channel is provided between the right support column and the side plate of the right frame.
[0011] This invention reduces the weight of the frame by using a rectangular channel, thus making the photovoltaic module lighter.
[0012] More preferably, the bottom length of the left frame is greater than the top length of the left frame, and the bottom length of the right frame is greater than the top length of the right frame.
[0013] This allows the border to maintain stability during use.
[0014] Further preferably, the thickness of the extended end is the same as the thickness of the short side of the L-shaped flap, and the thickness of the short side of the L-shaped flap is greater than the thickness of the long side of the L-shaped flap.
[0015] This invention optimizes the thickness of the extended end and the short side of the L-shaped flap, thereby increasing strength. Optimizing the thickness of the long side of the L-shaped flap ensures that it can be inserted into the opening of the right frame. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.
[0020] like Figures 1-2As shown, a waterproof frame for an integrated photovoltaic module includes multiple photovoltaic modules. Each photovoltaic module has a left frame 1 on its left side and a right frame 2 on its right side. The outer contours of both the left and right frames are E-shaped. The upper end of the left frame has a left receiving groove for accommodating the edge of the photovoltaic module. The top of the left frame has an extension end 3, and the end of the extension end has an L-shaped flap 4. The end of the L-shaped flap has an inwardly bent buckle 5. The upper end of the right frame has a right receiving groove for accommodating the edge of the photovoltaic module. There is a gap between the top edge of the right receiving groove and the top of the photovoltaic module. The top edge of the right receiving groove has an opening 6, and the edge of the opening has a flange 7. The flange engages with the buckle. The top length of the right frame is less than the length of the extension end, and the gap matches the extension end.
[0021] This invention features a sophisticated L-shaped flap as a water-guiding structure, effectively guiding water flow under rain impacts of varying angles and intensities. This reduces direct contact between water and photovoltaic modules, allowing for seamless integration with existing modules. Installation is simple, and maintenance costs are low. Its widespread adoption will significantly enhance the waterproofing capabilities of photovoltaic power plants, reducing maintenance costs and power generation losses caused by waterproofing issues. This is of great importance for promoting the sustainable development of photovoltaic power plants.
[0022] Further preferably, a left support column 8 is provided below the left receiving slot, with the top of the left support column fixed to the left receiving slot and the bottom of the left support column fixed to the bottom of the left frame; a right support column 9 is provided below the right receiving slot, with the top of the right support column fixed to the right receiving slot and the bottom of the right support column fixed to the bottom of the right frame. This utility model can improve the stability of the frame by adding support columns on both sides.
[0023] Further preferably, a rectangular channel is provided between the left support column and the side plate of the left frame, and another rectangular channel is provided between the right support column and the side plate of the right frame. This invention reduces the weight of the frame through the rectangular channels, thus achieving lightweight photovoltaic modules.
[0024] Further optimization involves ensuring that the bottom length of the left border is greater than the top length of the left border, and the bottom length of the right border is greater than the top length of the right border. This maintains the stability of the borders during use.
[0025] Further optimized, the thickness of the extended end is consistent with the thickness of the short side of the L-shaped flap, and the thickness of the short side of the L-shaped flap is greater than the thickness of the long side of the L-shaped flap. This invention optimizes the thickness of the extended end and the short side of the L-shaped flap, thereby increasing strength, and optimizes the thickness of the long side of the L-shaped flap to ensure insertion into the opening of the right frame.
[0026] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
