[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides two technical solutions:

[0021] like Figure 1-2The first embodiment is shown: a solid-insulated ring main unit splicing structure includes two solid-insulated ring main units 1 arranged side by side. The bottoms of the two solid-insulated ring main units 1 are respectively provided with a first bearing assembly 2 and a second bearing assembly 3 with identical structures. The first bearing assembly 2 includes a left bearing frame 4, a right bearing frame 5, casters 6, a square rod 7, splicing components 8, a double-sided rack 9, a telescopic rod 10, and a fan 11. The casters 6 are fixedly installed on the front and rear sides of the bottom of the left bearing frame 4 and the right bearing frame 5. The square rod 7 is fixedly installed on the opposite side walls of the left bearing frame 4 and the right bearing frame 5. The right bearing frame 5 is slidably sleeved on the outer wall of the square rod 7 to change the distance between the right bearing frame 5 and the left bearing frame 4. The two splicing components 8 are respectively fixedly installed on the front and rear sides of the bottom of the right bearing frame 5 for use with the second bearing assembly 3. The double-sided rack 9 on the side wall connects and locks the positions of the first bearing component 2 and the second bearing component 3. The double-sided rack 9 is fixedly installed on the outer wall of the left bearing frame 4. The telescopic rod 10 is fixedly installed on the opposite side walls of the left bearing frame 4 and the right bearing frame 5. The fan 11 is fixedly installed between the ends of the two telescopic rods 10. The right bearing frame 5 and the opposite side wall of the left bearing frame 4 are provided with square holes that are compatible with the square rod 7. The bottom of the square hole is threaded with a fastening bolt for limiting the movement of the square rod 7. The bottom of the solid insulated ring main unit 1 is provided with heat dissipation holes for dissipating heat. The position of the heat dissipation holes is opposite to the fan 11. The top of the left bearing frame 4 and the right bearing frame 5 are provided with baffles to prevent the solid insulated ring main unit 1 from slipping. The right side of the top of the right bearing frame 5 is provided with a notch so that there is no gap in the middle after splicing with the second bearing component 3.

[0022] like Figure 3-4 The second embodiment is shown, and its main difference from the first embodiment is that: a solid-insulated ring main unit splicing structure, the splicing component 8 includes a connecting box 81, and a first gear 83 and a second gear 84 are rotatably arranged on both sides of the connecting box 81 via a rotating shaft. The bottom end of the rotating shaft rotatably passes through the connecting box 81 and is provided with a gear rotation control mechanism. The gear rotation control mechanism includes a drive shaft 82, a positioning plate 85, a permanent magnet 86, an iron limiting plate 87, a limiting tooth 88, a connecting rod 89, and a limiting groove 810. The drive shaft 82 is fixedly arranged at the bottom end of the rotating shaft. Positioning disc 85 is rotatably mounted at the bottom end of transmission shaft 82. Permanent magnet 86 and iron limiting disc 87 are both sleeved on the outer wall of transmission shaft 82. Limiting tooth 88 is fixedly mounted at the bottom of iron limiting disc 87. Connecting rod 89 is fixedly mounted on the opposite side wall of connecting box 81 and positioning disc 85. Limiting grooves 810 for engaging with limiting tooth 88 are opened on both sides of the top of positioning disc 85. Sliding grooves are evenly opened on the outer wall of transmission shaft 82. A slider is fixedly mounted on the inner wall of iron limiting disc 87. The slider is slidably mounted inside the sliding groove. Permanent magnet 86 is fixedly sleeved on the outer wall of transmission shaft 82.

[0023] In use, the bottom of the two solid-insulated ring main unit bodies 1 are respectively equipped with a first bearing component and a second bearing component. Before installing the first bearing component 2 and the second bearing component 3, the distance between the left bearing frame 4 and the right bearing frame 5 is adjusted according to the current width of the solid-insulated ring main unit body 1. During adjustment, the right bearing frame 5 is pushed or pulled to slide along the outer wall of the square rod 7. When the distance is appropriate, the fastening bolts between the right bearing frame 5 and the square rod 7 are tightened to fix the distance between the left bearing frame 4 and the right bearing frame 5. Then, the second bearing component 3 is pushed so that the side with the double-sided rack 9 is close to the side of the first bearing component 2 with the splicing component 8. Since the positions of the double-sided rack 9 and the splicing component 8 are one-to-one, the double-sided rack 9 is inserted into the gap between the first gear 83 and the second gear 84. The two gears are subjected to the double-sided rack. Driven by the rack 9, the rack rotates. When the rack 9 is fully inside the connecting box 81, the first bearing component 2 and the second bearing component 3 are in contact with each other on their opposite sidewalls. Then, the iron limiting plate 87 slides down the drive shaft 82, so that the limiting tooth 88 enters one of the limiting grooves 810. Since the positioning plate 85 is fixed by the connecting rod 89 and the connecting box 81, and the iron limiting plate 87 can only slide up and down along the groove on the outer wall of the drive shaft 82, the position of the two gears is limited and they cannot rotate. When disassembling, slide the iron limiting plate 87 upward and use the permanent magnet 86 to hold the iron limiting plate 87, releasing the positioning plate 85 from fixing the position of the iron limiting plate 87. Thus, the rack 9 can be pulled out from between the first gear 83 and the second gear 84, that is, the first bearing component 2 and the second bearing component 3 are separated.
