To address these issues, this application provides a bracket device for PV construction.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a support device for photovoltaic construction.

[0006] The support device for photovoltaic construction provided in this application adopts the following technical solution:

[0007] A support device for photovoltaic construction includes a U-shaped inclined beam for supporting photovoltaic modules. A T-shaped crossbeam, a U-shaped crossbeam, and a C-shaped crossbeam are fixed to the top of the U-shaped inclined beam. The U-shaped crossbeam is located between the T-shaped crossbeam and the C-shaped crossbeam. Multiple photovoltaic modules are equidistantly arranged, and each photovoltaic module can slide between the T-shaped crossbeam and the C-shaped crossbeam, and also slide on the top of the U-shaped beam. Multiple Z-shaped pressure plates are fixed to the top of the T-shaped crossbeam for limiting the position of each photovoltaic module. A spacer strip and a limiting component for limiting the position of the spacer strip are slidably arranged between the T-shaped crossbeam and the C-shaped crossbeam. The spacer strip is located between two adjacent photovoltaic modules.

[0008] Preferably, the limiting component includes a spring, a limiting post, a connecting block, and a lever. Both ends of the spacer are provided with sliding grooves, and the inner walls of the two sliding grooves are provided with limiting grooves. One end of the spring is fixed to the side wall of the sliding groove, and the other end of the spring is fixed to the limiting post. The limiting post slides in the sliding groove, and the connecting block slides in the limiting groove. The bottom of the connecting block is fixed to the surface of the limiting post, and the top of the connecting block is fixed to the bottom of the lever. The lever slides on the top of the spacer. The T-shaped beam is provided with a through hole for the limiting post to pass through.

[0009] Preferably, the end of the limiting post away from the spacer is provided with a ball bearing.

[0010] Preferably, the top of the lever is provided with an anti-slip groove and the lever can cover the entire limiting groove.

[0011] Preferably, a fixing block 2 is provided on both sides of one end of the U-shaped beam, and a top baffle is fixed between the two fixing blocks 2, with one side of the top baffle abutting against one side of the photovoltaic module.

[0012] Preferably, a limiting opening is provided at the top of the U-shaped inclined beam, and a limiting block is fixed at the bottom of the U-shaped crossbeam, with the limiting block and the limiting opening being inserted into each other.

[0013] Preferably, the bottom of the T-shaped beam is provided with a fixing block, which is attached to the side wall of the U-shaped inclined beam.

[0014] Preferably, a fixing block three is fixed to the bottom of the C-shaped beam, and the fixing block three is attached to the side wall of the U-shaped inclined beam.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. By setting up Z-shaped pressure plates, T-shaped crossbeams, C-shaped crossbeams, and U-shaped crossbeams, and cooperating with U-shaped inclined beams for installation, the photovoltaic modules are slidably installed between the T-shaped and C-shaped crossbeams and on the top of the U-shaped crossbeams. This ensures accurate installation positioning and, compared with related technologies, guarantees the stability and firmness of the entire support structure. It effectively simplifies the installation steps, reduces the complex component assembly and debugging in traditional installation processes, and reduces the reliance on the professional skills of installers. Installers can quickly get started with the installation operation, which helps to improve installation efficiency and, in turn, shorten the project construction cycle and facilitate the rapid deployment of photovoltaic power generation systems.

[0017] 2. By using Z-shaped pressure plates in conjunction with T-shaped crossbeams, and with the Z-shaped pressure plates being fixed on one side, the photovoltaic modules can be firmly fixed, preventing them from shaking or shifting during operation. Compared with related technologies, this effectively enhances the stability of the entire photovoltaic power generation system. At the same time, the Z-shaped pressure plates, with their single-sided fixing method, not only ensure the fixing effect but also effectively improve the convenience of disassembly and assembly. When photovoltaic modules need to be replaced, staff only need to release the fixing of the corresponding Z-shaped pressure plates to easily remove the faulty photovoltaic modules from the bracket and install new modules, effectively shortening maintenance time and reducing maintenance costs and manpower input.

[0018] 3. By sliding spacers between T-shaped and C-shaped beams and equipping them with limiting components to restrict the spacers, the spacers, located between two adjacent photovoltaic modules, effectively separate them. Compared with related technologies, this effectively avoids collisions and interference between photovoltaic modules, further ensuring the installation stability and safety of the photovoltaic modules and extending their service life. Furthermore, when the spacers need maintenance or replacement, simply release the limiting components and slide the spacers out, effectively reducing the difficulty and intensity of operation and maintenance, decreasing the time and labor costs required for maintenance, and improving the overall operational reliability of the photovoltaic power generation system.

[0030] The present application will be further described in detail below with reference to Figures 1-10.

[0031] This application discloses a support device for photovoltaic construction. Referring to Figures 1-10, a support device for photovoltaic construction includes a U-shaped inclined beam 8 for supporting photovoltaic modules 3. A T-shaped crossbeam 2, a U-shaped crossbeam 4, and a C-shaped crossbeam 6 are fixed to the top of the U-shaped inclined beam 8. The U-shaped crossbeam 4 is located between the T-shaped crossbeam 2 and the C-shaped crossbeam 6. A fixing block 9 is provided at the bottom of the T-shaped crossbeam 2, and the fixing block 9 is attached to the side wall of the U-shaped inclined beam 8. A fixing block 13 is fixed at the bottom of the C-shaped crossbeam 6, and the fixing block 13 is attached to the side wall of the U-shaped inclined beam 8. A limiting opening 11 is provided at the top of the U-shaped inclined beam 8. A limiting block 10 is fixed at the bottom of the U-shaped crossbeam 4, and the limiting block 10 is inserted into the limiting opening 11. Fixing blocks 12 are provided on both sides of one end of the U-shaped crossbeam 4. A top baffle 5 is fixed between the two fixing blocks 12. One side of the top baffle 5 abuts against one side of the photovoltaic module 3. The short side design of the U-shaped crossbeam 4 is simple in structure and can improve its strength, ensuring that it supports the photovoltaic module 3. During construction, the T-shaped crossbeam 2, U-shaped crossbeam 4, and C-shaped crossbeam 6 are fixed to the top of the U-shaped inclined beam 8 in sequence, so that the fixing blocks 1 9 and 3 13 are respectively attached to the side wall of the U-shaped inclined beam 8. The limiting block 10 and the limiting port 11 are inserted and matched to ensure accurate installation position and stable and firm installation. The top baffle 5 is fixed between the two fixing blocks 12 to prevent the photovoltaic module from sliding out of the bracket during installation, ensuring the safety of the installation process and completing the convenient assembly of the bracket.

[0032] It should be noted that the U-shaped inclined beam 8 is finally secured to the T-shaped crossbeam 2, U-shaped crossbeam 4, and C-shaped crossbeam 6 with bolts, ensuring the stability and firmness of the entire support structure.

[0033] Multiple photovoltaic modules 3 are equidistantly arranged. Each photovoltaic module 3 can slide between the T-shaped beam 2 and the C-shaped beam 6, as well as on the top of the U-shaped beam 4, ensuring accurate installation. Multiple Z-shaped pressure plates 1 are fixed on the top of the T-shaped beam 2 to limit the position of each photovoltaic module 3. Spacer bars 7 and limiting components for limiting the spacer bars 7 are slidably arranged between the T-shaped beam 2 and the C-shaped beam 6. The spacer bars 7 are located between two adjacent photovoltaic modules 3. When installing photovoltaic modules 3, multiple photovoltaic modules 3 are first slidably placed on the T-shaped beam 2, C-shaped beam 6 and U-shaped beam 4 in sequence. By pushing, the photovoltaic modules 3 are equidistantly distributed. After all photovoltaic modules 3 are installed in place, the Z-shaped pressure plates 1 are used to limit and fix each photovoltaic module 3 with bolts to ensure the stability of the photovoltaic modules 3. At the same time, the spacer bars 7 are slidably installed between adjacent photovoltaic modules 3 to avoid collisions and interference between the photovoltaic modules 3. The limiting components limit the spacer bars 3, completing the entire installation process.

[0034] The T-shaped crossbeam 2, C-shaped crossbeam 6, and U-shaped crossbeam 4 together form a sliding track for installing the photovoltaic module 3, providing a flexible operating space for the installation of the photovoltaic module 3. Installers do not need to perform complex positioning and fixing operations; they only need to place the photovoltaic module 3 on the sliding track and push it. This effectively simplifies the installation steps, reduces the complex component assembly and debugging in the traditional installation process, and reduces the reliance on the professional skills of the installers. Installers can quickly get started with the installation operation, which helps to improve installation efficiency and thus shorten the project construction cycle and the rapid deployment of the photovoltaic power generation system.

[0035] It should be noted that the Z-shaped pressure plate 1 adopts a Z-shaped design, which has good stability. The fixing position is designed with a width of 20mm and a depth of 18mm, which facilitates the use of power tools. The two Z-shaped pressure plates 1 work together with the T-shaped crossbeam 2 to fix a photovoltaic module 3, ensuring the stability of the fixation and resisting wind and earthquakes. The single-sided fixing method not only ensures the fixing effect, but also effectively improves the convenience of disassembly and assembly. When the photovoltaic module 3 needs to be replaced, the staff only needs to release the fixation of the corresponding Z-shaped pressure plate 1 to easily remove the faulty photovoltaic module 3 from the bracket and install the new photovoltaic module 3, which effectively shortens the maintenance time and reduces the maintenance cost and manpower input.

[0036] The C-shaped crossbeam 6 is designed to guide the photovoltaic module 3 during installation, ensuring smooth installation. Before use, the inner C-shaped surface of the C-shaped crossbeam 6 is coated with polytetrafluoroethylene, and the long side of the C-shaped crossbeam 6 is 1mm thicker than the photovoltaic module 3, ensuring stable installation while pushing it. The short C-shaped plate of the C-shaped crossbeam 6 is 20mm, ensuring stable installation and preventing any impact on the replacement of the photovoltaic module 3 in case of failure.

[0037] The U-shaped inclined beam 8 provides support, and its bottom can be adapted to various current designs, making it highly adaptable. The Z-shaped pressure plate 1 serves to fix the photovoltaic module 3, making installation convenient. By reducing handling work and fixing it on one side, it ensures ease of installation, structural stability, and maintenance.

[0038] It should be further noted that the T-shaped beam 2, U-shaped beam 4, and C-shaped beam 6 are all coated with polytetrafluoroethylene (PTFE) on the surfaces that contact the photovoltaic module 3. PTFE is acid and alkali resistant, high temperature resistant, atmospheric aging resistant, radiation resistant, and has low permeability, ensuring its long-term use in atmospheric exposure. Furthermore, it has self-lubricating properties, requiring no additional lubricant, and its coefficient of friction is approximately 0.02. An adult can easily move dozens of photovoltaic modules. The formula for calculating the coefficient of friction is:

[0039] F = μ * F n

[0040] In the formula, μ is the coefficient of kinetic friction, also called the sliding friction coefficient. It is only related to the material and the roughness of the contact surface, and is not related to the contact area; n is the normal force. The larger the tilt angle of the photovoltaic module, the smaller the friction force.

[0041] Referring to Figures 4-7, the limiting assembly includes a spring 15, a limiting post 16, a connecting block 19, and a lever 20. Both ends of the spacer 7 have sliding grooves 14, and the inner walls of both sliding grooves 14 have limiting grooves 18. One end of the spring 15 is fixed to the side wall of the sliding groove 14, and the other end of the spring 15 is fixed to the limiting post 16. The limiting post 16 slides within the sliding groove 14. The connecting block 19 slides within the limiting groove 18. The bottom of the connecting block 19 is fixed to the surface of the limiting post 16, and the top of the connecting block 19 is fixed to the bottom of the lever 20. The lever 20 slides on the top of the spacer 7. The T-shaped beam 2 has a through hole for the limiting post 16 to pass through. During installation, the lever 20 is moved, causing the connecting block 19 to slide within the limiting groove 18. Because the bottom of the connecting block 19 is fixed to the surface of the limiting post 16... The movement of the connecting block 19 will cause the limiting post 16 to slide in the slide groove 14. At this time, the spring 15 is compressed, allowing the spacer 7 to slide freely between the T-shaped beam 2 and the C-shaped beam 6. After the spacer 7 is slid to the desired new position, the lever 20 is released. The spring 15 returns to its extension under its own elastic force, pushing the limiting post 16 to slide in the opposite direction in the slide groove 14. The limiting post 16 passes through the through hole at the corresponding position on the T-shaped beam 2. At the same time, the connecting block 19 slides in the opposite direction in the limiting groove 18 back to the initial position. The lever 20 is also reset synchronously. At this time, the spacer 7 is fixed between the T-shaped beam 2 and the C-shaped beam 6. The two sides of the spacer 7 are respectively attached to the two sides of the two photovoltaic modules 3. There is no need to use complicated tools or perform cumbersome operation steps, which improves the overall installation and maintenance efficiency.

[0042] It should be noted that the through holes opened on the T-shaped crossbeam 2 play a precise positioning role. When the limiting post 16 passes through the through hole, it can ensure that the spacer 7 is accurately fixed in the predetermined position, ensuring that the spacing between the spacer 7 and the photovoltaic module 3 is uniform and consistent, which is conducive to the overall performance optimization of the photovoltaic power generation system. In order to ensure the connection stability and good ventilation between two adjacent photovoltaic modules 3, the middle section of the spacer 7 can be hollow or have several through holes.

[0043] The limiting groove 18 guides the sliding of the connecting block 19, further ensuring the stability of the limiting post 16 during movement, and enabling the spacer 7 to be accurately positioned during unlocking and locking, thus improving the accuracy and reliability of installation.

[0044] Referring to Figure 6, a ball bearing 17 is rotatably provided at the end of the limiting post 16 away from the spacer 7. When the limiting post 16 contacts and slides relative to the inner wall of the T-shaped beam 2 and the C-shaped beam 6, friction is generated. The ball bearing 17 effectively reduces the resistance of the limiting post 16 when it moves, making it easier and less strenuous for the operator to push the spacer 7, thus improving the smoothness and efficiency of the entire operation process.

[0045] Referring to Figure 7, the top of the lever 20 is provided with an anti-slip groove and the lever 20 can cover the entire limiting groove 18. The anti-slip groove increases the friction between the hand and the lever 20, so that the operator can apply force more stably when pushing the lever 20, reducing the possibility of hand slippage and improving the safety and convenience of operation. The lever 20 can cover the entire limiting groove 18, which can effectively prevent external debris from entering the limiting groove 18, ensuring the smooth sliding of the connecting block 19 in the limiting groove 18, and helping to extend the service life of the components in the limiting groove 18.
