[0002] With the growth of the global economy and the increase in population, the demand for energy continues to rise. Traditional fossil fuels not only have limited reserves, but also cause serious environmental problems during extraction and use, such as greenhouse gas emissions, air pollution, etc. Against this background, the development and utilization of renewable energy have received extensive attention. As a clean, abundant, and sustainable energy source, solar energy has seen rapid development in its applications. Photovoltaic power generation is a technology that directly converts solar energy into electrical energy. In the past few decades, the efficiency of photovoltaic cells has been continuously improved, and the cost has gradually decreased, making photovoltaic power generation increasingly important in the energy field.

[0003] A photovoltaic frame is a metal frame structure used to fix and protect photovoltaic modules, providing a stable mechanical structure support for photovoltaic modules, preventing deformation or damage due to external forces during transportation, installation, and use, ensuring the fixed position of photovoltaic cells and encapsulation materials, protecting the internal cells and circuits. Installation holes are usually provided on the frame to facilitate the installation of photovoltaic modules on the bracket to achieve the best lighting angle and position.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figure 1-7, the present utility model provides a technical solution: a high-strength photovoltaic frame that is easy to assemble, including a support plate 1, a first limiting frame 2, a second limiting frame 3, a positioning block 4, a locking block 5, a storage slot 6, a connecting plate 7, a limiting sliding frame 8, an installation slider 9, a buffer connecting rod 10, an extrusion slider 11, a piston rod 12, a gas guiding pipe 13, a sealing airbag 14, and an auxiliary cushion block 15. On the support plate 1, a first limiting frame 2 is provided on its upper surface, and a second limiting frame 3 is provided on the upper surface of the support plate 1. One end of the first limiting frame 2 and the second limiting frame 3 facing each other is arranged in a staggered manner. Installation holes are provided on the surface of the staggered ends of the first limiting frame 2 and the second limiting frame 3. When using this device, first stack the staggered ends of the first limiting frame 2 and the second limiting frame 3, and stack and install the second limiting frame 3 on one side with the auxiliary cushion block 15, and fix the first limiting frame 2, the second limiting frame 3, the auxiliary cushion block 15, and the support plate 1 with bolts.

[0033] Two positioning blocks 4 are fixed on the lower surface of one end of the second limiting frame 3. Two locking blocks 5 are slidably connected to the lower side surface of the positioning blocks 4. A groove is provided on the upper surface of one end of the first limiting frame 2, and a limiting groove is provided on the inner wall of the groove of the first limiting frame 2. A spring is connected between the locking block 5 and the positioning block 4. A spring is connected between the limiting sliding frame 8 and the installation slider 9. Two adjacent buffer connecting rods 10 are rotatably connected, and two adjacent buffer connecting rods 10 are arranged in a staggered manner. When stacking the first limiting frame 2 and the second limiting frame 3, the positioning blocks 4 on the lower surface of one end of the second limiting frame 3 are positioned by being inserted into the groove on the surface of the first limiting frame 2, which improves the installation efficiency. Subsequently, the spring inside the positioning block 4 pushes the locking block 5 to engage and fix with the first limiting frame 2, further improving the installation stability.

[0034] Storage slots 6 are fixed on the side surfaces of both the first limiting frame 2 and the second limiting frame 3. A connecting plate 7 is placed between the two storage slots 6. Two limiting sliding frames 8 are fixed on the surface of the connecting plate 7. The linkage sealing mechanism includes an extrusion slider 11, which is slidably connected to the side surfaces of both the first limiting frame 2 and the second limiting frame 3 respectively. One end of the extrusion slider 11 is fixedly connected to a piston rod 12. Gas guiding pipes 13 are embedded and installed inside both the first limiting frame 2 and the second limiting frame 3. Sealing airbags 14 are fixed on the upper surfaces of both the first limiting frame 2 and the second limiting frame 3. After installing the first limiting frame 2 and the second limiting frame 3, insert the two connecting plates 7 into the storage slots 6 for installation respectively. The spring inside the limiting sliding frame 8 pushes the installation slider 9 to slide, so that the installation slider 9 drives the buffer connecting rod 10 to rotate, facilitating the two buffer connecting rods 10 to support the first limiting frame 2 and the second limiting frame 3 on both sides, thereby improving the stability of the device in the horizontal direction.

[0035] There are 2 mounting sliders 9 slidingly connected to the surface of the limit slide carriage 8. A buffer connecting rod 10 is rotatably connected to the surface of the mounting slider 9. A linkage sealing mechanism is arranged inside the first limit frame 2 and the second limit frame 3. It drives the piston rod 12 to slide through the air guide pipe 13 to inflate and seal the airtight balloon 14 by means of the extrusion slider 11. The side surface of the extrusion slider 11 is designed to be arc-shaped. Springs are connected between the extrusion slider 11 and the first limit frame 2 and the second limit frame 3 respectively. The piston rod 12 is communicated with the air guide pipe 13, and the air guide pipe 13 is communicated with the airtight balloon 14. An auxiliary cushion block 15 is arranged at the lower end of the second limit frame 3 on one side. A groove is arranged on the surface of the auxiliary cushion block 15, and the auxiliary cushion block 15 and the locking block 5 form a snap connection. Moreover, mounting holes are arranged on the surface of the auxiliary cushion block 15. When the photovoltaic panel is placed in the grooves at the upper ends of the first limit frame 2 and the second limit frame 3, at this time, since the connecting plate 7 pushes the extrusion slider 11 to move, the extrusion slider 11 drives the piston rod 12 to push the air in the air guide pipe 13 into the airtight balloon 14, so that the airtight balloon 14 is inflated and seals the surface of the photovoltaic panel, thereby improving the blocking effect on sand, wind and rain.

[0036] Working principle: When using this easily assembled high-strength photovoltaic frame, the first limit frame 2, the second limit frame 3 and the auxiliary cushion block 15 are stacked in a staggered manner, and then the support plate 1, the first limit frame 2, the second limit frame 3 and the auxiliary cushion block 15 are fixed by bolts. The positioning block 4 on the surface of the second limit frame 3 facilitates the quick positioning of the first limit frame 2 and the auxiliary cushion block 15, and the stability is improved by clamping the first limit frame 2 and the auxiliary cushion block 15 with the locking block 5. The connecting plate 7 is installed through the storage slot 6, so that the limit slide carriage 8 on the surface of the connecting plate 7 pushes the mounting slider 9 to slide through the spring, and the mounting slider 9 drives the buffer connecting rod 10 to rotate to support the first limit frame 2 and the second limit frame 3 on both sides. After the photovoltaic panel is placed, the extrusion slider 11 and the piston rod 12 are pushed to slide through the connecting plate 7, so that the air guide pipe 13 inflates the airtight balloon 14 for airtight protection, increasing the overall practicability.
