Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module connection structure technology, and specifically relates to a photovoltaic module clamping block reinforcement component. Background Technology

[0002] Photovoltaic module clamps are key connectors in solar photovoltaic power generation systems, primarily used to fix photovoltaic panels and improve the overall structural stability. Existing π-shaped clamps are similar to the structure shown in Chinese utility model patent CN205811910U. While π-shaped clamps have better load-bearing capacity than U-shaped clamps, these types of clamps all have open cross-sections, making deformation, instability, and buckling relatively common, especially after prolonged use, making it difficult to guarantee the clamp's effectiveness in fixing the photovoltaic modules. To enhance load-bearing and deformation resistance, the only solution is to increase the wall thickness, which is not economically viable. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a photovoltaic module clamping block reinforcement, which solves the common deformation failure problem of current clamping blocks, improves the stress state of the cross section, and can economically improve the stress performance of thin-walled cross sections.

[0004] According to the technical solution of this utility model, this utility model provides a photovoltaic module pressing block reinforcement component. The pressing block body includes a pressing block bottom wall, pressing block side walls extending upward on both sides of the pressing block bottom wall, and pressing block side walls extending outward from the top of the pressing block side walls to form a pressing plate. A bottom wall bolt hole is opened in the middle of the pressing block bottom wall. The pressing block reinforcement component includes a reinforcement component top wall, and reinforcement component side walls extending downward on both sides of the reinforcement component top wall. The pressing block reinforcement component is matched and disposed between the two pressing block side walls, and the lower end of the reinforcement component side wall is in contact with or connected to the pressing block bottom wall.

[0005] In some embodiments, a top wall bolt hole is provided in the middle of the top wall of the reinforcement.

[0006] In some implementations, the top wall bolt holes are aligned with the bottom wall bolt holes.

[0007] In some embodiments, the bolt holes on the top wall are elliptical, and the length of the ellipse is parallel to the side wall of the pressure block.

[0008] In some implementations, the top wall of the reinforcement is parallel to the bottom wall of the pressure block.

[0009] In some embodiments, the top wall of the reinforcement is close to or corresponds to the pressure plate.

[0010] In some implementations, the top wall of the reinforcement is a rolled part that is independent of the main body of the briquette.

[0011] In some implementations, the top wall of the reinforcing member is welded to the main body of the pressure block or integrally formed.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] 1. The photovoltaic module pressing block reinforcement component of this utility model is set inside the pressing block body, providing a fulcrum for the pressing block body, increasing the support of the pressing block sidewall from three sides to four sides, providing effective support for the pressing block sidewall and pressing plate, optimizing the stress state, greatly improving the overall load-bearing capacity of the pressing block, and effectively ensuring the normal power generation operation of the photovoltaic module.

[0014] 2. The photovoltaic module pressing block reinforcement of this utility model forms a closed cross section after being combined with the existing pressing block, which enhances the cross section's resistance to buckling deformation and strengthens its stress performance.

[0015] 3. The size of the photovoltaic module pressing block reinforcement component can be adjusted according to the actual stress requirements during application. Compared with simply increasing the wall thickness of the existing pressing block, it can achieve better stress performance, and save more raw materials and lower costs.

[0016] 4. When the photovoltaic module pressing block reinforcement of this utility model is used as a separate accessory, it can be used only for the parts that need to be reinforced, and its use is flexible; when the pressing block reinforcement is integrally formed or welded to the pressing block, its stress performance can be further improved.

[0025] This invention provides a photovoltaic module clamping block reinforcement component, which solves the common deformation failure problem of current clamping blocks, improves the stress state of the cross section, and can economically improve the stress performance of open thin-walled cross sections.

[0026] Please see Figures 1 to 6 The present invention provides a photovoltaic module pressing block reinforcement component 2, which is used in combination with the pressing block body 1 or integrally formed.

[0027] The pressure block body 1 includes a pressure block bottom wall 11, with pressure block side walls 12 extending upwards on both sides of the bottom wall 11. The top of the pressure block side walls 12 extends outwards to form a pressure plate, and a bottom wall bolt hole 13 is provided in the middle of the bottom wall 11. More specifically, the pressure block bottom wall 11 and the pressure block side walls 12 are perpendicular to each other, the bottom surface of the pressure plate is parallel to the bottom wall 11, and the bottom surface of the pressure plate has anti-slip teeth. The pressure block body 1 may be a π-shaped pressure block or a similar structure.

[0028] The pressure block reinforcement 2 includes a top wall 21, and side walls 22 extending downward from both sides of the top wall 21. More specifically, the top wall 21 and the side walls 22 are perpendicular to each other, and the lower end surface of the side walls 22 is flat. Optionally, there is a curved transition section between the top wall 21 and the side walls 22.

[0029] The pressure block reinforcement 2 is matchedly disposed between the two pressure block sidewalls 12; specifically, the width of the pressure block reinforcement 2 is b1, and the distance between the two pressure block sidewalls 12 of the pressure block body 1 is also b1, so that the pressure block reinforcement 2 fits into the pressure block body 1. The lower end of the reinforcement sidewall 22 is in contact with or connected to the bottom wall 11 of the pressure block.

[0030] As a supplementary explanation, the height h1 of the block reinforcement 2 is not greater than the height of the block sidewall 12 of the block body 1, so that the top wall 21 of the reinforcement is lower than the upper end of the block sidewall 12, and the top wall 21 of the reinforcement can provide support for the block sidewall 12. Generally, the length l1 of the block reinforcement 2 is not greater than the length of the block body 1. Preferably, for example, the block reinforcement 2 is located in the middle 1 / 3 to 1 / 2 region of the block body 1, so that the two reinforcement sidewalls 22 are more evenly distributed within the length range of the block body 1, which is more conducive to the stress performance.

[0031] In the illustrated embodiment, a top wall bolt hole 23 is provided in the middle of the top wall 21 of the reinforcing member, which serves as a bolt mounting hole. Furthermore, the top wall bolt hole 23 is aligned with the bottom wall bolt hole 13, and a bolt passes through both the top wall bolt hole 23 and the bottom wall bolt hole 13 for installation and positioning.

[0032] Preferably, the top wall bolt hole 23 is elliptical (or quasi-elliptical), and the length direction of the ellipse is parallel to the side wall 12 of the pressure block. For example, in the illustrated embodiment, the length of the ellipse of the top wall bolt hole 23 is l2, which is larger than a circle with a radius of r1 and slightly larger than the bolt diameter. Using an elliptical top wall bolt hole 23 is more advantageous for situations where the photovoltaic module and pressure block are tilted as a whole, and it also helps to reduce the requirements for hole opening accuracy and assembly accuracy.

[0033] In the illustrated embodiment, the top wall 21 of the reinforcing member is parallel to the bottom wall 11 of the pressure block, forming a generally rectangular closed cavity in the middle. Of the six faces of this cuboid, three faces are the inner surfaces of the pressure block reinforcing member 2, and the other three faces are the inner surfaces of the pressure block body 1. A bolt is then inserted into the bolt hole 23 on the top wall and the bolt hole 13 on the bottom wall in the middle of the cavity for positioning and fastening.

[0034] Preferably, the top wall 21 of the reinforcement is close to or corresponds to the pressure plate. Figure 5 , Figure 6 As shown, the height of the pressure block reinforcement 2 is h1, and the height from the lower surface of the pressure plate of the pressure block body 1 to the upper surface of the bottom wall 11 of the pressure block is also h1. Thus, after installation, the lower surface of the pressure plate is flush with the upper surface of the top wall 21 of the reinforcement. The position of the top wall 21 of the reinforcement is high and close to the pressure plate, or close to the opening of the pressure block body, which can provide better support and anti-deformation function.

[0035] The briquetting reinforcement 2 and the briquetting body 1 can be integrally formed or formed separately. When used as a separate accessory, the briquetting reinforcement 2 can be used only for the parts requiring reinforcement. As a separately formed reinforcement, in some embodiments, the top wall 21 of the reinforcement is a rolled part independent of the briquetting body 1, which is easy to process and produce, and has stable quality. The specific wall thickness and length are determined by calculation, and it can be directly added to the existing briquetting block to achieve the reinforcement effect. In other embodiments, the top wall 21 of the reinforcement and the briquetting body 1 are welded together or integrally formed, such as integral casting. Using integrally formed / fixed briquetting reinforcement 2 and briquetting body 1 can further improve the stress performance.

[0036] In summary, the photovoltaic module clamping block reinforcement of this invention is disposed within the clamping block body, providing a fulcrum for the clamping block body. This increases the support of the clamping block sidewall from three sides to four sides, providing effective support for the clamping block sidewall and pressure plate, optimizing the stress state, and significantly improving the overall load-bearing capacity of the clamping block, effectively ensuring the normal power generation operation of the photovoltaic module. The photovoltaic module clamping block reinforcement of this invention is equivalent to adding a π-shaped pad to the existing clamping block, forming a closed cross-section after combination with the existing clamping block, enhancing the cross-sectional resistance to buckling deformation and improving the load-bearing performance. When applied, the size of the clamping block reinforcement of this invention can be adjusted according to actual stress requirements. Compared with simply increasing the wall thickness of the existing clamping block, it achieves better load-bearing performance, saves raw materials, and has lower costs. It can be used for clamping block bodies with thin-walled cross-sections, and both the clamping block body and the clamping block reinforcement can adopt thin-walled cross-sections, forming sufficient supporting force through the vertical connection between the plate surfaces. When the photovoltaic module pressing block reinforcement component of this utility model is used as a separate accessory, it can be used only for the parts that need reinforcement, making it flexible in use; when the pressing block reinforcement component is integrally formed or welded to the pressing block, its stress performance can be further improved.
