Description

Technical Field

[0001] The utility model belongs to the relevant technical field, and in particular relates to a photovoltaic component frame that prevents dust accumulation. Background Art

[0002] The frame of a photovoltaic module refers to the edge part installed around the photovoltaic (solar cell) module, usually made of aluminum alloy. In the frame of a photovoltaic module, side A is the side against the frame groove. This side cooperates with the front of the laminate, so the surface requirements are very strict, and there must not be any defects such as bright lines, black spots, color differences, etc. Side B generally has some decorative lines or waves or arc structures. On the one hand, such a design increases the aesthetics, and on the other hand, it is also non-slip and easy to carry. Side B is the side of the photovoltaic module and is a decorative surface. Side C is on the back of the laminate, against the backplane in the laminate. With the rapid expansion of the photovoltaic industry in these areas, the development of the industry has also ushered in some challenges. Among them, the impact of environmental factors on the efficiency of photovoltaic modules is one of the aspects that people are concerned about. The northern region is often attacked by strong winds and sandstorms. These natural phenomena will not only deposit a lot of dust on the photovoltaic panels to block sunlight, but also lead to a decrease in power generation efficiency.

[0003] However, the A-side design of the traditional photovoltaic module frame makes it easy for dust, rain and snow to accumulate at the connection between the frame and the module. Long-term accumulation of dust and water will cause the module to be shaded and reduce its efficiency, affecting the service life of the module. In addition, the bearing surface of the glue overflow groove of the existing photovoltaic module frame is a flat design, which is easy to cause glue overflow and contamination on the A-side of the frame. It is difficult to clean and may cause pollution to the assembly line, which has a certain impact on production capacity. Utility Model Content

[0004] The purpose of the present utility model is to provide a photovoltaic module frame that is dust-proof, so as to solve the problem that the A-side design of the traditional photovoltaic module frame proposed in the above-mentioned background technology is easy to cause dust, rain and snow to accumulate at the connection between the frame and the module. Long-term accumulation of dust and water will cause the module to be shaded and reduce its efficiency, affecting the service life of the module. In addition, the bearing surface of the glue overflow groove of the existing photovoltaic module frame is a flat design, which is easy to cause glue overflow on the A side of the frame to cause pollution, which is difficult to clean and may cause pollution to the production line, having a certain impact on production capacity.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a photovoltaic module frame that prevents dust accumulation, comprising a support frame and a bottom plate arranged at the bottom of the support frame;

[0006] The top of the support frame is provided with an angled support, the inner side of the support frame is provided with a support portion, a bottom overflow glue groove is provided on the support portion, a side overflow glue groove is provided on the inner wall of the support frame, a glue storage groove is provided at the connection between the support portion and the support frame, the support frame and the support portion form an installation groove, the bottom of the support portion is provided with an inner connecting plate, and a plurality of reinforcing ribs are respectively provided on the bottom surface of the support portion and the bottom plate, and the support portion, the bottom plate, the support frame and the inner connecting plate form a frame cavity.

[0007] Preferably, the installation groove is used to install the laminate, and the abutment angle is integrally connected to the support frame. The abutment angle can abut against the side of the laminate when the laminate is installed.

[0008] Preferably, the support part is integrally connected to the support frame, the side overflow glue groove on the support frame and the bottom overflow glue groove on the support part are both wave grooves, and the glue storage groove at the connection between the support part and the support frame can store excess glue.

[0009] Preferably, the A side of the frame is the side that is adjacent to the frame notch, and the height of the A side of the frame does not exceed the height of the laminate. When the laminate is installed in the installation slot, it needs to be 0-0.5 mm higher than the A side of the frame.

[0010] Preferably, after installation, the support frame needs to be fixed by side pressure blocks and middle pressure blocks, and a T-shaped foot is provided at the bottom of the side pressure block, and the T-shaped foot is integrally connected to the side pressure block, and the T-shaped foot is used to support the side pressure block.

[0011] Preferably, the side pressure blocks are provided with mounting holes, which are used to fix the side pressure blocks. The side pressure blocks and the middle pressure blocks are respectively provided with pressure plates on the top, which are integrally connected to the side pressure blocks and the middle pressure blocks. The bottoms of the pressure plates are provided with EPDM rubber, which can act as a buffer between the side pressure blocks, the middle pressure blocks and the laminate to prevent the glass from breaking when the laminate is installed.

[0012] Preferably, the bottom plate is integrally connected to the support frame, the inner connecting plate is integrally connected to the bottom plate and the support portion, and the reinforcing rib is integrally connected to the support portion and the bottom plate. The reinforcing rib can improve the strength of the frame.

[0013] Compared with the prior art, the present invention provides a photovoltaic module frame that prevents dust accumulation and has the following beneficial effects:

[0014] 1. By setting up the side overflow glue groove and the bottom overflow glue groove, wave grooves are added on the support part and the support frame plane. The wave groove design allows the silicone to fully contact the overflow glue groove, which can enhance the contact area between the silicone and the frame, enhance the shear force, and enhance the overflow resistance of the silicone, so that the silicone will not exceed the edge during the overflow process. At the same time, it can also ensure that the edge is evenly stressed during mechanical load. Through the setting of the glue storage groove, excess silicone can be filled into the glue storage groove. The glue storage groove can store the silicone to further prevent silicone overflow.

[0015] 2. Since the height of the frame surface A does not exceed the laminate, the height of the laminate is the same as or slightly higher than the frame surface A. When the photovoltaic module is installed at an angle, the dust and snow at the connection between the frame and the module are more likely to fall to the ground, making it easier to clean the module and avoid shading the module.

[0016] 3. Through the setting of side pressure blocks, middle pressure blocks and EPDM rubber, when the components are installed using side pressure blocks and middle pressure blocks, since the A side of the frame does not block the laminate, the pressure blocks directly act on the glass surface of the laminate. Glass is brittle. When conventional pressure blocks directly apply force on the glass surface of the laminate, it is easy to cause explosion. By adding EPDM rubber (EPDM) to the inside of the side pressure blocks and middle pressure blocks to buffer between the metal pressure blocks and the glass surface of the laminate, it can effectively avoid glass breakage during installation and protect the integrity of the laminate.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides Figure 1-4 The dust-proof photovoltaic module frame shown includes a support frame 1 and a bottom plate 5 arranged at the bottom of the support frame 1;

[0024] A corner support 6 is provided on the top of the support frame 1, a support portion 10 is provided on the inner side of the support frame 1, a bottom overflow glue groove 9 is provided on the support portion 10, a side overflow glue groove 7 is provided on the inner wall of the support frame 1, a glue storage groove 8 is provided at the connection between the support portion 10 and the support frame 1, the support frame 1 and the support portion 10 form an installation groove 11, an inner connecting plate 2 is provided at the bottom of the support portion 10, a plurality of reinforcing ribs 4 are respectively provided on the bottom surface of the support portion 10 and the bottom plate 5, and the support portion 10, the bottom plate 5, the support frame 1 and the inner connecting plate 2 form a frame cavity 3.

[0025] In this embodiment, the photovoltaic module frame refers to the edge part installed around the photovoltaic (solar cell) module, which is usually made of aluminum alloy material. It provides necessary support for the photovoltaic module, enhances its mechanical strength and prevents deformation. Secondly, it can protect the edge of the module to prevent damage caused by external factors (such as impact, scratches, etc.). It also facilitates the installation of the photovoltaic module on the bracket, improves the flexibility and safety of the installation, helps to increase the sealing of the module, prevents moisture and dust from invading, and extends the service life of the module. The installation method of the photovoltaic module frame is as follows. Before installing the laminate 12, it is necessary to first confirm whether there is any foreign matter on the surface of the frame, clean the entire frame, and then inject silicone into the inside of the frame. Carefully place the laminate 12 on the frame to ensure that the corner 6 is against the laminate 12. Finally, when the silicone is completely solidified, the installation of the photovoltaic module frame is completed.

[0026] like Figure 1 and Figure 2 As shown, the installation groove 11 is used to install the laminate 12, and the corner 6 is integrally connected to the support frame 1. The corner 6 can be against the side of the laminate 12 when the laminate 12 is installed. The support part 10 is integrally connected to the support frame 1. The side overflow glue groove 7 on the support frame 1 and the bottom overflow glue groove 9 on the support part 10 are both wavy grooves. The glue storage tank 8 at the connection between the support part 10 and the support frame 1 can store excess glue. The A side of the frame is the side against the frame groove. The height of the A side of the frame does not exceed the height of the laminate 12. When the laminate 12 is installed in the installation groove 11, it needs to be 0~0.5mm higher than the A side of the frame.

[0027] Preferably, by setting the side overflow glue groove 7, the bottom overflow glue groove 9 and the glue storage groove 8, a wave groove is added on the support part and the support frame plane. The wave groove design allows the silicone to fully contact the side overflow glue groove 7 and the bottom overflow glue groove 9, which can enhance the contact area between the silicone and the frame, enhance the shear force, and enhance the overflow resistance of the silicone, so that the silicone will not exceed the edge during the overflow process. At the same time, it can also ensure that the edge is evenly stressed during mechanical load. The excess silicone can be filled into the glue storage groove 8, and the glue storage groove 8 can store the silicone to further prevent the silicone from overflowing.

[0028] Preferably, the height of the laminate is the same as or slightly higher than the height of the frame A surface. When the photovoltaic module is installed at an angle, dust and snow at the connection between the frame and the module are more likely to fall to the ground, making it easier to clean the module and avoid shading the module.

[0029] like Figure 3 and Figure 4 As shown, after the support frame 1 is installed, it needs to be fixed by the side pressure block 16 and the middle pressure block 18. A T-shaped foot 14 is provided at the bottom of the side pressure block 16, and the T-shaped foot 14 is integrally connected to the side pressure block 16. The T-shaped foot 14 is used to support the side pressure block 16. A mounting hole 13 is provided on the side pressure block 16, and the mounting hole 13 is used to fix the side pressure block 16. A pressure plate 17 is provided on the top of the side pressure block 16 and the middle pressure block 18 respectively, and the pressure plate 17 is integrally connected to the side pressure block 16 and the middle pressure block 18. EPDM rubber 15 is provided at the bottom of the pressure plate 17. The EPDM rubber 15 can be used as a buffer between the side pressure block 16 and the middle pressure block 18 and the laminate 12 to prevent the glass from breaking when the laminate 12 is installed. The bottom plate 5 is integrally connected to the support frame 1, the inner connecting plate 2 is integrally connected to the bottom plate 5 and the support part 10, the reinforcing rib 4 is integrally connected to the support part 10 and the bottom plate 5, and the reinforcing rib 4 can improve the strength of the frame.

[0030] Preferably, by setting the side pressure blocks 16, the middle pressure blocks 18 and the EPDM rubber 15, when the assembly is installed using the side pressure blocks 16 and the middle pressure blocks 18, since the frame A surface does not block the laminate, the pressure blocks directly act on the glass surface of the laminate 12. Glass is brittle, and when conventional pressure blocks directly apply force on the glass surface of the laminate 12, it is easy to cause the glass to explode. By adding the EPDM rubber (15) inside the side pressure blocks 16 and the middle pressure blocks 18, it is buffered between the metal pressure blocks and the glass surface of the laminate 12, which can effectively avoid glass breakage during installation and protect the integrity of the laminate.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
