The two rings 18 are respectively threadedly connected to the two ends of the threaded rod 13. The support frame 15 is lifted by the lifting assembly so that the U-shaped frame 16 is lifted out of the connecting groove 25, so that multiple connecting grooves 25 are connected with the outside world, thereby realizing a rapid increase in the air circulation area inside the substation outer box 1, improving the heat dissipation capacity inside the substation outer box 1, and affecting the overall thermal management capacity inside the substation outer box 1.

[0028] like Figure 1-5As shown, a guide rod 14 is fixedly connected to the inside of the substation outer box 1 at the same height as the threaded rod 13. The guide rod 14 is symmetrically distributed with the threaded rod 13. A lifting assembly is also provided on the guide rod 14. Two rings 18 in the lifting assembly corresponding to the guide rod 14 are respectively slidably connected to the two ends of the guide rod 14 and are symmetrically arranged. A synchronization rod 17 is fixedly connected between the adjacent rings 18 in the two lifting assemblies. By setting the guide rod 14 and the lifting assembly on the guide rod 14, the other end of the support frame 15 can be supported, thereby improving the lifting stability of the support frame 15.

[0029] like Figure 1-5 As shown, a drive motor 24 is fixedly installed at the upper end of the outer box 1 of the substation, and a driving bevel gear 23 is fixedly connected to the output end of the drive motor 24. A driven bevel gear 22 is fixedly connected to the middle part of the threaded rod 13. The driven bevel gear 22 and the driving bevel gear 23 are meshed and connected to each other.

The spiral directions of the two ends of the threaded rod 13 are opposite, so that the threaded rod 13 can drive the two end rings 18 to approach each other when rotating, so that the angle of the ring 18 changes, thereby causing the support frame 15 to perform vertical linear motion and lift it, so that the U-shaped frame 16 lifts out of the connecting groove 25, and when the threaded rod 13 rotates and drives its corresponding ring 18, the synchronous rod 17 can also drive the two end rings 18 on the guide rod 14 to move during the movement, so that the connecting rod 19 on the guide rod 14 also changes its angle synchronously to lift the support frame 15, making the lifting of the support frame 15 more stable, and quickly increasing the air circulation area in the substation outer box 1 through multiple connecting grooves 25, thereby improving the heat dissipation capacity inside the substation outer box 1, and affecting the overall thermal management capacity of the substation outer box 1.
