[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a photovoltaic module with a base 3 to prevent loosening, including a photovoltaic module body 1, the photovoltaic module body 1 being fixed inside a frame 2, and a base 3 being provided at the bottom of the frame 2, the base 3 including an upper support 9 and a lower support 6;

[0026] Both sides of the lower support 6 are provided with side frames 8, and a transmission rod 17 is slidably connected to the side frame 8. One end of the transmission rod 17 is fixedly connected to a connecting plate 11, and the other end of the transmission rod 17 is fixedly connected to a limit plate 4.

[0027] A vertical plate 15 is fixed below the transmission rod 17, and a spring 13 is provided between the vertical plate 15 and the side frame 8.

[0028] In use, side frames 8 are set on both sides of the lower support 6, and movable limiting plates 4 are connected in the side frames 8. After the pentagonal bolts 10 are installed, the limiting plates 4 are placed directly above the pentagonal bolts 10 so that they are in close contact with and press against the pentagonal bolts 10 to prevent them from loosening and falling off. This achieves the limitation of the pentagonal bolts 10, avoids the pentagonal bolts 10 from moving, and thus ensures the stability of the base 3.

[0029] Example 2: Based on Example 1, the transmission rod 17 is provided in two sets, and the two sets of transmission rod 17 are symmetrically distributed about the central axis of the side frame 8. The spring 13 is located below the transmission rod 17. One end of the spring 13 is fixedly connected to the side frame 8, and the other end of the spring 13 is fixedly connected to the upright plate 15. The connecting plate 11 is located outside the side frame 8. The connecting plate 11 is square plate-shaped, and a handle 12 is fixed on the surface of the connecting plate 11. The limiting plate 4 is located directly above the pentagonal bolt 10, and the lower surface of the limiting plate 4 is in contact with the upper surface of the pentagonal bolt 10.

[0030] When using the base 3, the specific operation is as follows when installing it on the ground 21: First, fix the guide post 5 on the ground 21 according to the position of the guide hole 18 on the base 3. After fixing the guide post 5, move the base 3 to align the guide hole 18 on the base 3 with the guide post 5 to limit the base 3. Then, install the five-pointed star bolts 10 in sequence. First, manually pull the handle 12 to move the drive rod 17, which in turn moves the limiting plate 4, causing the limiting plate 4 to move into the side frame 8, so that the mounting hole 1... When the transmission rod 17 moves, the upright plate 15 will move synchronously, thereby applying pressure to the spring 13. The spring 13 will be compressed at this time, maintaining the state of the limiting plate 4. Subsequently, the pentagonal bolt 10 is installed in the mounting hole 19, so that the base 3 is fixed on the ground 21. At this time, the pulling force on the handle 12 is released. Under the rebound action of the spring 13, the transmission rod 17 and the limiting plate 4 will move. The limiting plate 4 will move to the top of the pentagonal bolt 10 and make contact, thereby pressing and limiting the pentagonal bolt 10.

[0031] Example 3: Based on Example 2, the frame 2 is rectangular, and the base 3 is provided in four sets. The four sets of base 3 are respectively set near the four ends of the lower surface of the frame 2. The upper support 9 is located above the lower support 6. The top of the upper support 9 is fixedly connected to the frame 2, and the bottom of the upper support 9 is fixedly connected to the lower support 6. The lower support 6 is hollow inside, and a reinforcing beam 7 is fixed inside the hollow of the lower support 6. The reinforcing beam 7 is "X" shaped. In use, the "X" shaped reinforcing beam 7 is fixed inside the hollow of the lower support 6. This structure greatly enhances the strength and stability of the base 3, making it more able to withstand external pressure and wind load.

[0032] The base 3 is installed on the ground 21, and a guide post 5 is fixed on the ground 21. The top of the guide post 5 is rounded. Two sets of guide holes 18 are opened on both sides of the lower support 6. The two sets of guide holes 18 are symmetrically distributed about the central axis of the lower support 6. The outer wall of the guide post 5 and the inner wall of the guide hole 18 are slidably connected. The inner side of the two sets of guide holes 18 is provided with mounting holes 19. Pentagonal bolts 10 are installed in the mounting holes 19. When in use, the docking of the guide post 5 and the guide hole 18 realizes the limiting of the base 3, preventing the base 3 from moving in subsequent operations and ensuring the stability of the base 3. The end face of the guide post 5 is rounded to improve the smoothness of the connection. The reserved mounting holes 19 facilitate the subsequent installation of pentagonal bolts 10.

[0033] Several equally spaced diagonal bracing plates 16 are fixed at the bottom of the side frame 8. The other side of the diagonal bracing plates 16 is fixedly connected to the lower support 6. In use, the diagonal bracing plates 16 can increase the connection strength between the side frame 8 and the lower support 6 and improve the overall stability.

[0034] The inner bottom wall of the side frame 8 is provided with a sliding groove 14, and the bottom of the upright plate 15 is fixed with a slider 20. The slider 20 and the sliding groove 14 are slidably connected. In use, when the transmission rod 17 moves and drives the upright plate 15 to move, the slider 20 will move synchronously in the sliding groove 14, which will further support and guide the movement of the upright plate 15, improve the stability of the movement of the upright plate 15, and ensure the stability of the spring 13 in the rebound operation.

[0035] In actual use, side frames 8 are set on both sides of the lower support 6, and movable limiting plates 4 are connected in the side frames 8. After the pentagonal bolts 10 are installed, the limiting plates 4 are placed directly above the pentagonal bolts 10, so that they are in close contact with and press against the pentagonal bolts 10 to prevent them from loosening and falling off. This achieves the limitation of the pentagonal bolts 10 and avoids the movement of the pentagonal bolts 10, thereby ensuring the stability of the base 3. This avoids the problem that in actual applications, especially in the scenario of ground installation 21, the pentagonal bolts 10 of the base 3 are prone to loosening and falling off the base 3, which would cause the entire base 3 to loosen and thus affect the stability and power generation efficiency of the photovoltaic module.
