Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figures 1-12A prefabricated photovoltaic box inverter base structure device includes a base 1. Side plates 4 are provided on both sides of the upper surface of the base 1. First positioning grooves 19 are formed at the bottom of each side plate 4. Two first positioning rods 10 are welded to the upper surface of the base 1, and the two first positioning rods 10 are respectively engaged with the two first positioning grooves 19. A front plate 2 and a rear plate 6 are provided between the two side plates 4, located on the other two sides of the base 1. Second positioning rods 30 are welded to both sides of the front plate 2 and the rear plate 6. Two second positioning grooves 20 are formed on the opposite sides of each of the two side plates 4. Positioning rod 30 engages with second positioning slot 20. Both side uprights 4 are detachably connected to front upright 2 and rear upright 6 via connecting components. A fixing bracket 26 is detachably connected to the front upright 2, rear upright 6, and two side uprights 4 via bolts. The fixing bracket 26 is detachably connected to the base 1 via bolts. A fixing plate 9 is fixed to the upper surface of the fixing bracket 26 via bolts. A top cover 5 is detachably connected to the top of the front upright 2, rear upright 6, and two side uprights 4 via bolts. Multiple mounting brackets 27 for installing inverters are fixed to one side of the rear upright 6 via bolts. Ventilation components are provided on opposite sides of both side uprights 4. One side panel 4 is placed on one side of the base 1, and the first positioning rod 10 on the base 1 is engaged into the first positioning groove 19 on the side panel 4 to position and install the side panel 4. Then, the front panel 2 and the side panel 4 are placed on the base 1, and the second positioning rods 30 on the front panel 2 and the side panel 4 are engaged into the second positioning groove 20 on the side panel 4. Subsequently, another side panel 4 is installed on the base 1 through the first positioning rod 10 and the first positioning groove 19, and the second positioning rods 30 on the front panel 2 and the rear panel 6 are engaged into the second positioning groove 20 on the side panel 4. Finally, the fixing bracket 26 is bolted to the front panel 2. The rear upright plate 6, base 1, and two side upright plates 4 are connected and fixed. Then, the fixing plate 9 is fixed to the fixing frame 26 with bolts. Then, the side upright plates 4, rear upright plate 6, and front upright plate 2 are connected by connecting components. Then, the top cover 5 is fixed to the top of the front upright plate 2, rear upright plate 6, and side upright plate 4 with bolts, thus completing the assembly of the photovoltaic box. When the photovoltaic box needs to be transported, the top cover 5, front upright plate 2, rear upright plate 6, and side upright plate 4 are disassembled to disassemble the photovoltaic box into individual parts for transportation. This can reduce the volume of the photovoltaic box and facilitate the collective transportation of multiple photovoltaic boxes.

[0037] The connecting assembly includes multiple insert rods 33. Multiple slots 29 are provided on the opposite sides of the front upright plate 2 and the rear upright plate 6 near the second positioning rod 30. The insert rods 33 are respectively engaged within the slots 29. A connecting block 13 is integrally formed on one side of each insert rod 33, and the connecting block 13 contacts the side upright plate 4. An insertion hole is provided on one side of the connecting block 13, into which a screw 32 is inserted. Multiple threaded holes 31 are provided on one side of the second positioning rod 30, and the screws 32 are threaded into the threaded holes 31. The front upright plate 2, the rear upright plate 6, and the two side upright plates 4 are all recessed on one side. Connector 13 is located in the recess of side plate 4, and two second positioning slots 20 are located on the protrusions of side plate 4. Insert rod 33 into slot 29 so that connector 13 is located in the groove on side plate 4. Then rotate screw 32 so that screw 32 enters threaded hole 31, thereby strengthening the connection between side plate 4 and front plate 2 and rear plate 6, making the connection between side plate 4 and front plate 2 and rear plate 6 more stable. Two cable trays 28 and multiple mounting brackets 27 are located in the recess of rear plate 6. Cable trays 28 can neatly arrange the wires during inverter installation.

[0038] In this invention, to facilitate air circulation inside the photovoltaic box and achieve heat dissipation, the ventilation assembly includes multiple protective frames 12. Two ventilation holes 8 are provided on one side of each of the two side panels 4. The multiple protective frames 12 are respectively fixed to the opposite sides of the two side panels 4 by bolts, and the protective frames 12 cover the ventilation holes 8. Multiple ventilation holes 18 are provided at the bottom of each of the multiple protective frames 12. A baffle 22 is provided inside each of the multiple ventilation holes 8. Alternating grooves 23 are provided on both sides of each baffle 22. A connecting shaft 25 is welded to one side of the groove 23, and the connecting shaft 25 is rotatably connected to the protective frame 12. A torsion spring 24 is sleeved on the outside of the connecting shaft 25, and the two ends of the torsion spring 24 are fixed to the protective frame 12 and the baffle 22 respectively. One side of the baffle 22 has an arc surface. When wind blows, the wind will blow the baffle 22 inside the protective frame 12 on one side of the side panel 4 to rotate upward, thereby exposing the vent 18 and allowing wind to enter the photovoltaic box. Then the wind will blow the baffle 22 inside the protective frame 12 on the other side panel 4 to rotate upward. The baffle 22 on the protective frame 12 rotates downwards, allowing air to flow from inside the photovoltaic box and carrying away the heat inside. On opposite sides of the two side panels 4, above the vent 8, are welded U-shaped frames 11, with the protective frame 12 located inside the U-shaped frames 11. The U-shaped frames 11 seal the gap between the protective frame 12 and the side panels 4, preventing rainwater from entering the photovoltaic box. Multiple feet 15 are welded to the bottom of the base 1, and the bottom of the base 1 is designed to lift the photovoltaic box. The heightening component includes multiple threaded grooves 14, all of which are located at the bottom of the base 1. Each threaded groove 14 is threaded with a threaded rod 16. A heightening column 7 is welded to the bottom of the threaded rod 16. Multiple anti-slip protrusions 17 are integrally formed at the bottom of the heightening column 7. The heightening column 7 is connected to the threaded grooves 14 on the base 1 via the threaded rods 16, thereby increasing the installation height of the photovoltaic box. An installation opening is provided on one side of the front upright plate 2, and a door panel 3 is hinged to the installation opening.

[0039] The working principle of this embodiment is as follows: First, place one side plate 4 on one side of the base 1, and engage the first positioning rod 10 on the base 1 with the first positioning groove 19 on the side plate 4 to position and install the side plate 4. Then, place the front plate 2 and the side plate 4 on the base 1, and engage the second positioning rods 30 on the front plate 2 and the side plate 4 with the second positioning groove 20 on the side plate 4. Next, install the other side plate 4 on the base 1 using the first positioning rod 10 and the first positioning groove 19, and engage the second positioning rods 30 on the front plate 2 and the rear plate 6 with the second positioning groove 20 on the side plate 4. Finally, connect and fix the fixing bracket 26 to the front plate 2, the rear plate 6, the base 1, and the two side plates 4 using bolts. Next, the fixing plate 9 is fixed to the fixing frame 26 with bolts. Then, the insertion rod 33 is inserted into the slot 29, so that the connecting block 13 is located in the groove on the side plate 4. Then, the screw 32 is turned so that the screw 32 enters the threaded hole 31, thereby strengthening the connection between the side plate 4 and the front plate 2 and the rear plate 6. Then, the top cover 5 is fixed to the top of the front plate 2, the rear plate 6 and the side plate 4 with bolts, thus completing the assembly of the photovoltaic box. When the photovoltaic box needs to be transported, the top cover 5, the front plate 2, the rear plate 6 and the side plate 4 are disassembled to disassemble the photovoltaic box into individual parts for transportation. This can reduce the volume of the photovoltaic box, facilitate the collective transportation of multiple photovoltaic boxes, and save costs.
