[0002] Prefabricated substations, also known as box-type substations or compact substations, are complete power distribution units that integrate high-voltage switchgear, transformers, and low-voltage power distribution equipment into a single enclosed enclosure. Prefabricated substations typically require photovoltaic (PV) module mounting structures, which are specialized mechanical systems designed to fix and mount PV modules, ensuring their stable and efficient operation under various environmental conditions.

[0003] Patent CN210469200U discloses a photovoltaic module mounting structure that places the photovoltaic panel between a lower mounting frame and an upper mounting frame, and then uses mounting studs to fix the lower mounting frame and the upper mounting frame together, so that the photovoltaic panel is fixed between the lower mounting frame and the upper mounting frame. The installation and disassembly are relatively convenient. However, when using this photovoltaic module mounting structure, it usually requires a large number of bolts to install the photovoltaic module, and it can only install photovoltaic modules within a certain specification range, so its application scope is still relatively limited.

[0022] Example 1, please refer to Figures 1-4 A prefabricated photovoltaic module installation structure for a substation includes a main body 1 and a connecting groove plate 2 snapped into the middle of the main body 1. Bearing rods 3 are fixedly connected to the middle of both sides of the connecting groove plate 2, and both sets of bearing rods 3 are fixedly connected to the main body 1. A first horizontal lead screw shaft 6 penetrating the main body 1 is provided on the inner side of the connecting groove plate 2. Two sets of first sliders 7 are sleeved on the outer side of the first horizontal lead screw shaft 6. A first limiting plate 8 is fixedly connected to the upper side of each of the two sets of first sliders 7. Two sets of limiting grooves 16 and two sets of auxiliary grooves 17 are provided on the main body 1. A second horizontal lead screw shaft 11 is provided on the inner side of each of the two sets of limiting grooves 16. A second slider 12 is sleeved on the outer side of each of the two sets of second horizontal lead screw shafts 11. A second limiting plate 13 is fixedly connected to the upper side of each of the two sets of second sliders 12. An auxiliary rod 15 is fixedly connected to the inner side of each of the two sets of auxiliary grooves 17. An auxiliary block 14 is sleeved on the outer side of each of the two sets of auxiliary rods 15.

[0023] The main body 1 has a first groove 4 and a second groove 9 through the middle of both sides. A moving motor 5 is fixedly installed inside the first groove 4, and a first horizontal lead screw 6 is fixedly connected to the output end of the moving motor 5. A symmetrical threaded section is provided on the outer side of the first horizontal lead screw 6. Both sets of first sliders 7 are threadedly connected to the first horizontal lead screw 6, and both sets of first sliders 7 are located inside the connecting groove plate 2. Both sets of first limiting plates 8 are T-shaped.

[0024] In this embodiment, the first horizontal lead screw shaft 6 is threadedly connected to the first slider 7 so that the two sets of first limiting plates 8 can move relative to each other.

[0025] The second groove 9 is fitted with a dual-axis motor 10, and two sets of second horizontal lead screw shafts 11 are respectively fixedly connected to the two output ends of the dual-axis motor 10. The external threads of the two sets of second horizontal lead screw shafts 11 are symmetrically arranged. The two sets of second sliders 12 are respectively threadedly connected to the two sets of second horizontal lead screw shafts 11, and the two sets of second sliders 12 are respectively located inside the two sets of limiting grooves 16.

[0026] In this embodiment, the second slider 12 is threadedly connected to the second horizontal lead screw shaft 11 so that the two sets of second limiting plates 13 can move relative to each other.

[0027] The two sets of auxiliary blocks 14 are fixedly connected to the two sets of second limiting plates 13 respectively, and the two sets of second limiting plates 13 are both inverted T-shaped. The two sets of auxiliary blocks 14 are located inside the two sets of auxiliary grooves 17 respectively.

[0028] In this embodiment, the auxiliary block 14 and the auxiliary rod 15 are slidably connected to the auxiliary groove 17 to facilitate the stable movement of the second limiting plate 13.

[0029] Specifically, by activating the moving motor 5 within the first groove 4, the first horizontal lead screw shaft 6 is rotated, thereby causing the two sets of first sliders 7 to move relative to each other along the connecting groove plate 2 under the cooperation of symmetrical threaded sections. This, in turn, causes the two sets of first limiting plates 8 to move relative to each other until both sets of first limiting plates 8 are in contact with the photovoltaic panel. Next, the dual-axis motor 10 within the second groove 9 is activated, causing the two sets of second horizontal lead screw shafts 11 to rotate. This, in turn, causes the two sets of second sliders 12 to move relative to each other along the two sets of limiting grooves 16 under the cooperation of symmetrical external threads. This, in turn, causes the two sets of second limiting plates 13 to move relative to each other through the auxiliary block 14 and auxiliary rod 15 in cooperation with the auxiliary groove 17 until both sets of second limiting plates 13 are in contact with the photovoltaic panel. This method can position and install photovoltaic panels of different lengths and widths, has a wide range of applications, does not require the use of a large number of bolts, and has high installation efficiency.

[0030] Example 2, please refer to Figures 1-4 A prefabricated photovoltaic module installation structure for a substation includes a support body 21 located below a connecting trough plate 2.

Two sets of support columns 18 are located on the lower side of the main body 1. The two sets of support columns 18 are connected to the main body 1 by connecting hinges 19. A second support plate 26 is fixedly connected to the lower end of each set of support columns 18.

[0031] A lifting motor 22 is fixedly installed at the bottom of the support body 21, and a vertical screw shaft 23 is fixedly connected to the output end of the lifting motor 22. The vertical screw shaft 23 is threadedly connected to the lifting column 24, and the lifting column 24 is slidably connected to the support body 21. The upper end of the support body 21 is located between two sets of limiting plates 25.

[0032] In this embodiment, the vertical lead screw shaft 23 is threadedly connected to the lifting column 24 so that the lifting column 24 can move up and down along the support body 21.

[0033] Specifically, by activating the lifting motor 22 at the bottom of the support body 21, the vertical lead screw shaft 23 is rotated. This causes the lifting column 24 to move upward along the support body 21 through the threaded connection between the vertical lead screw shaft 23 and the lifting column 24. Subsequently, the main body 1 is tilted and rotated by the two sets of limiting plates 25 in conjunction with the connecting hinges 19 on the two sets of support columns 18. This achieves the tilt adjustment function of the photovoltaic module installation structure, thereby improving the power generation efficiency of the photovoltaic system and facilitating the installation and removal of the photovoltaic modules.
