To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.
[0034] Below, please refer to the appendix. Figure 1 and Figure 8 The present invention describes a border strip, which includes a frame and a drainage component.
[0035] The frame includes a base plate 1 and a support plate 2 arranged opposite to each other; and a first side plate 31 and a second side plate 32 connecting the base plate 1 and the support plate 2. The first side plate 31 is disposed between the base plate 1 and the support plate 2, and the second side plate 32 extends along the base plate 1 toward the support plate 2 and is disposed above the support plate 2. A limiting plate 4 is provided at the top of the second side plate 32, and the limiting plate 4 is perpendicular to the second side plate 32 to form an L-shaped limiting mounting groove 101.
[0036] It is worth noting that the base plate 1, support plate 2, first side plate 31, second side plate 32, and limiting plate 4 are all long, flat profiles. The dimensions of long, flat profiles are generally limited by their length, width, and thickness. (See reference...) Figure 8 As can be seen, in this utility model, the width direction of the base plate 1, support plate 2, and limiting plate 4 is the X-axis extension direction; the thickness direction of the base plate 1, support plate 2, and limiting plate 4 is the Y-axis extension direction; the length direction of the base plate 1, support plate 2, and limiting plate 4 is the Z-axis extension direction; the thickness direction of the first side plate 31 and the second side plate 32 is the X-axis extension direction; the width direction of the first side plate 31 and the second side plate 32 is the Y-axis extension direction; and the length direction of the first side plate 31 and the second side plate 32 is the Z-axis extension direction.
[0037] The widths of the base plate 1 and the support plate 2 can be equal, or the width of the base plate 1 can be greater than the width of the support plate 2. Preferably, the width of the base plate 1 can be greater than the width of the support plate 2, thereby enabling the base plate 1 to better support the laminate 6. Specifically, a protrusion can also be provided at the end of the base plate 1 away from the second side plate 32, thereby facilitating the subsequent installation of photovoltaic modules.
[0038] The first side plate 31 is positioned between the base plate 1 and the support plate 2, meaning the width of the second side plate 32 is equal to the distance between the base plate 1 and the base plate 2. This allows the laminate 6 to be placed more stably on the support plate 2.
[0039] The width of the second side plate 32 is greater than the width of the first side plate 31. The end of the second side plate 32 is connected to the limiting plate 4, thereby forming an L-shaped limiting installation groove 101, which can better install the laminate 6 and make the laminate 6 more tightly set in the installation groove 101.
[0040] The width of the limiting plate 4 can be equal to or less than the width of the support plate 2. Preferably, the width of the limiting plate 4 is less than the width of the support plate 2, which makes it easier for the laminate 6 to enter the mounting groove 101.
[0041] The drainage assembly includes a first groove 51 that partially penetrates the limiting plate 4 along its width direction and a second groove 52 that partially penetrates the second side plate 32 along its width direction; the opening end of the first groove 51 is located on the outer surface of the limiting plate 4 away from the second side plate 32; the outlet end of the first groove 51 is located inside the limiting plate 4 and communicates with the opening end of the second groove 52; the outlet end of the second groove 52 is located on the lower surface of the second side plate 32 near the bottom plate 1.
[0042] Specifically, in the width direction of the limiting plate 4, that is... Figure 8 In the X-coordinate extension direction shown, the opening end of the first groove 51 is provided on the outer surface of the limiting plate 4 away from the second side plate 32. The first groove 51 extends along the X-coordinate into the interior of the limiting plate 4, partially penetrating the interior of the limiting plate 4, that is, its outlet end is located inside the limiting part 544 and does not completely penetrate the outer surface of the other end of the limiting plate 4 near the second side plate 32; in the width direction of the second side plate 32, that is... Figure 8 As shown in the Y-coordinate extension direction, the second groove 52 has an opening end at the outlet end connecting to the first groove 51, that is, the opening end of the second groove 52 is located inside the outlet end of the first groove 51, or the opening end of the second groove 52 includes the outlet end of the first groove 51. The second groove 52 partially penetrates the second side plate 32, that is, its opening end does not completely penetrate the upper surface away from the bottom plate 1; the outlet end of the second groove 52 is located on the lower surface of the second side plate 32 near the bottom plate 1.
[0043] This invention, by providing mutually perpendicular first grooves 51 and second grooves 52 on the frame strip, allows rainwater to flow smoothly from the surface of the photovoltaic laminate 6 into the drainage channel and be quickly discharged, reducing the time water remains on the module surface. Furthermore, the drainage component designed in this invention retains the complete structure of the top limit portion, without affecting the overall structural strength of the frame strip, thus extending the service life of the photovoltaic module.
[0044] In one alternative approach, at least two drainage components are provided along the length of the second side plate 32.
[0045] In one alternative approach, such as Figure 2 As shown, a filter device 53 is installed in the first groove 51. This could be a filter screen, filter cotton, etc. It effectively prevents debris such as leaves and soil from entering the drainage channel and causing blockages, ensuring the long-term effectiveness of the drainage assembly.
[0046] In one specific embodiment, the filter device 53 is a filter cotton. For example, synthetic fiber filter cotton, non-woven filter cotton, glass fiber filter cotton, or activated carbon filter cotton; the surface of the filter cotton has a loose and porous structure, which allows water to enter the first groove 51 and prevents branches, fallen leaves, etc. from entering; thus preventing blockage of the first groove 51 and the second groove 52, ensuring the long-term effectiveness of the drainage component.
[0047] Specifically, the width of the filter cotton is equal to the width of the first groove 51, that is, the size of the filter cotton along the length of the limiting plate 4 is equal to the size of the first groove 51; the thickness of the filter cotton is equal to the height of the first groove 51, that is, the size of the filter cotton along the thickness of the limiting plate 4 is equal to the size of the first groove 51; thus, the filter cotton can completely cover the opening end of the first groove 51, preventing branches, fallen leaves, soil and the like from entering the first groove 51.
[0048] Preferably, the length of the filter cotton is greater than the depth of the first groove 51; that is, the size of the filter cotton along the width direction of the limiting plate 4 is greater than the size of the first groove 51; thereby, the filter cotton can be made to completely cover the opening end of the first groove 51, preventing branches, fallen leaves, soil and the like from entering the first groove 51.
[0049] In one alternative approach, such as Figure 2 As shown, a flow guiding device 54 is provided in the second groove 52. This can further and quickly guide rainwater out, avoiding the problem of water evaporating on the surface of the photovoltaic laminate 6 and leaving dust.
[0050] Specifically, such as Figure 3As shown, the flow guiding device 54 is a flow guiding box, which includes a first inner plate 541, a second outer plate 542, and a side plate 543 disposed between the first inner plate 541 and the second outer plate 542. The height of the first inner plate 541 is less than the height of the second outer plate 542. That is, the dimension of the second outer plate 542 along the length direction of the second side plate 32 is greater than the dimension of the first inner plate 541 along the length direction of the second side plate 32. This makes the first inner plate 541, the second outer plate 542, and the two side plates 543 form a structure with a semi-open upper half and a hollow lower half. The hollow upper half can effectively guide rainwater into the space formed by the first inner plate 541, the second outer plate 542, and the two side plates 543. And because the height of the second outer plate 542 is greater than the height of the first inner plate 541, and the length of the second outer plate 542 is greater, it can prevent rainwater from entering the gap of the flow guiding box and the second groove 52 and damaging the inner surface of the second groove 52.
[0051] Preferably, the upper end face of the first inner plate 541 is not higher than the upper end face of the support plate 2; the upper end face of the second outer plate 542 is not lower than the lower end face of the limiting plate 4. The filter device 53 needs to be inserted into the first groove 51. The fact that the upper end face of the first inner plate 541 is not higher than the upper end face of the support plate 2 facilitates the installation of the filter device 53. The fact that the upper end face of the second outer plate 542 is not lower than the lower end face of the limiting plate 4 prevents the filter device 53 from being installed in the gap between the second outer plate 542 and the second groove 52, thereby allowing rainwater to be quickly guided into the inverted guide box.
[0052] Furthermore, a limiting part 544 is provided on the upper end surface of the second outer plate 542 to facilitate the installation of the flow guiding device 54. The limiting part 544 and the second outer plate 542 form a receiving space, in which the filter device 53 is installed, thereby preventing the flow guiding device 54 from falling out of the second groove 52.
[0053] The second aspect of this utility model provides a photovoltaic module, including the frame strip and laminate 6 provided in the first aspect of this utility model, wherein the laminate 6 is partially disposed in the L-shaped limiting mounting groove 101.
[0054] like Figure 4-8 As shown, the frame strip includes a frame and a flow-guiding assembly; the frame includes a base plate 1 and a support plate 2 arranged opposite to each other; and a first side plate 31 and a second side plate 32 connecting the base plate 1 and the support plate 2. The first side plate 31 is disposed between the base plate 1 and the support plate 2, and the second side plate 32 extends along the base plate 1 towards the support plate 2 and is disposed above the support plate 2. A limiting plate 4 is provided at the top of the second side plate 32, and the limiting plate 4 is perpendicular to the second side plate 32 to form an L-shaped limiting mounting groove 101; the laminate 6 is installed in the L-shaped limiting mounting groove 101. The laminate 6 is a photovoltaic panel prepared by laminating battery modules, glass, EVA, etc.
[0055] The drainage assembly includes a first groove 51 that partially penetrates the limiting plate 4 along its width direction and a second groove 52 that partially penetrates the second side plate 32 along its width direction; the opening end of the first groove 51 is located on the outer surface of the limiting plate 4 away from the second side plate 32; the outlet end of the first groove 51 is located inside the limiting plate 4 and communicates with the opening end of the second groove 52; the outlet end of the second groove 52 is located on the lower surface of the second side plate 32 near the bottom plate 1.
[0056] The first groove 51 is provided on the limiting plate 4 above the laminate 6; the second groove 52 is provided on the second side plate 32 connected to the limiting plate 4. Thus, when rainwater, fallen leaves, soil and other debris accumulate on the laminate 6, the first groove 51 and the second groove 52, which are perpendicular to each other, can allow rainwater to flow smoothly from the surface of the photovoltaic laminate 6 into the drainage channel and be discharged quickly, reducing the retention time of water on the surface of the module.
[0057] The structure and process of the frame strip of the first aspect and the photovoltaic module of the second aspect of this utility model are described below with a specific embodiment. It is worth understanding that the following description is merely illustrative and not a specific limitation of this utility model.
[0058] like Figure 1-8 As shown, a frame strip includes a frame body, which includes a base plate 1 and a support plate 2 disposed opposite to each other; and a first side plate 31 and a second side plate 32 connecting the base plate 1 and the support plate 2. The first side plate 31 is disposed between the base plate 1 and the support plate 2, and the second side plate 32 extends along the base plate 1 toward the support plate 2 and is disposed above the support plate 2. A limiting plate 4 is provided at the top of the second side plate 32, and the limiting plate 4 is perpendicular to the second side plate 32 to form an L-shaped limiting mounting groove 101; a laminate 6 is installed in the L-shaped limiting mounting groove 101 by adhesive.
[0059] A first groove 51 is formed by penetrating the width direction of the limiting plate 4, and a second groove 52 is formed by penetrating the width direction of the second side plate 32. The opening end of the first groove 51 is located on the outer surface of the limiting plate 4 away from the second side plate 32. The outlet end of the first groove 51 is located inside the limiting plate 4 and communicates with the opening end of the second groove 52. The outlet end of the second groove 52 is located on the lower surface of the second side plate 32 near the bottom plate 1.
[0060] A filter cotton is provided in the first groove 51; the width of the filter cotton is equal to the width of the first groove 51, the thickness of the filter cotton is equal to the height of the first groove 51, and the length of the filter cotton is greater than the depth of the first groove 51.
[0061] A flow guiding device 54 is provided in the second groove 52. The flow guiding device 54 includes a first inner plate 541, a second outer plate 542, and a side plate 543 disposed between the first inner plate 541 and the second outer plate 542. The height of the first inner plate 541 is less than the height of the second outer plate 542. The upper end face of the first inner plate 541 is flush with the upper end face of the support plate 2. The upper end face of the second outer plate 542 is flush with the lower end face of the limiting plate 4. A limiting part 544 is provided on the upper end face of the second outer plate 542, and the limiting part 544 and the second outer plate 542 form a receiving space for installing filter cotton. This also realizes the installation of the flow guiding device 54, so that the flow guiding device 54 will not fall off the second groove 52.
[0062] When rainwater, fallen leaves, and dirt fall onto the laminate 6, the rainwater is filtered through the filter cotton and flows through the first groove 51 into the guide device 54 of the second groove 52, and is discharged below through the guide device 54. The fallen leaves and dirt are blocked by the filter cotton and are left on the laminate, and will not flow into the first groove 51 or the second groove 52 to cause blockage of the flow-guiding components. They can be removed later by rainwater or wind or manual cleaning, and will not affect the performance and service life of the photovoltaic module.
