[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: See Figure 1-5 The utility model provides a technical solution: a prefabricated box-type substation. This application is mainly aimed at improving the problem that the box-type substation lacks a mobile structure in the prior art. When moving it, it is mostly hoisted by a crane, which is troublesome to operate, and it is not convenient for the crane to enter and work in narrow terrain areas. The specific scheme is as follows: it includes a box body 1, a base 2 is provided under the box body 1, wherein the base 2 and the box body 1 are welded, and a sliding assembly 3 is provided inside the base 2, and the sliding assembly 3 can facilitate the box body 1 to roll on the ground.

[0022] See also Figure 2 and Figure 4 The sliding assembly 3 includes a transmission shaft 31, which is rotatably connected to the box body 1. There are two transmission shafts 31, and the transmission shafts 31 are arranged perpendicularly to the opposite side of the box body 1. Driven gears 32 are fixedly installed at both ends of the transmission shaft 31, and support legs 38 are meshed and connected to the inner sides of adjacent driven gears 32. The support legs 38 are movably connected to the box body 1, and adjacent support legs 38 are distributed in a square shape. The support legs 38 are arranged between adjacent transmission shafts 31, and the support legs 38 and the transmission shafts 31 are parallel to each other. Rollers 39 are arranged below the support legs 38. After the external force drives the transmission shaft 31 to rotate, the driven gear 32 rotates, and through the meshing action of the driven gear 32 and the support leg 38, the support leg 38 can move upward or downward; specifically, after the transmission shaft 31 drives the driven gear 32 to rotate clockwise, the support leg 38 can move from bottom to top, and then the roller 39 at the lower end of the support leg 38 is retracted into the base 2; at this time, it is convenient to place the box-type substation stably; similarly, after the transmission shaft 31 rotates counterclockwise, the support leg 38 can move from top to bottom, and then the roller 39 at the lower end of the support leg 38 is moved out from the base 2. In this process, the box body 1 is higher than the ground, and the contact between the box body 1 and the ground changes from surface contact to rolling contact, making the substation easier to move.

[0023] Furthermore, a driving gear 33 is provided between adjacent driven gears 32, and the driving gear 33 is fixedly mounted on the transmission shaft 31. A driving rack 34 is provided above the transmission shaft 31, and the driving rack 34 and the transmission shaft 31 are perpendicular to each other, and the driving rack 34 is movably connected to the housing 1. The driving rack 34 meshes with the driving gear 33. After the driving rack 34 is driven by an external force and moves to the left or right, the driving gear 33 and the driving rack 34 mesh with each other, and when the driving rack 34 moves from left to right, the transmission shaft 31 can be rotated clockwise; similarly, when the driving rack 34 moves from right to left, the transmission shaft 31 rotates counterclockwise.

[0024] See also Figure 1 and Figure 2 , a screw rod 35 is rotatably connected to the left end of the driving rack 34, and the screw rod 35 is arranged above the transmission shaft 31, and the center of the screw rod 35 and the transmission shaft 31 are perpendicular. The screw rod 35 is connected to the housing 1 by a thread, and a limit block 36 is clamped at the outer end of the screw rod 35, and a limit slot 37 for inserting the limit block 36 is provided at the corresponding position of the housing 1. The centers of the screw rod 35 and the limit block 36 in the limit slot 37 are colinear. After the limit block 36 is moved out of the limit slot 37, the limit block 36 is separated from the restriction of the housing 1, and the operator rotates the screw rod 35 and the limit block 36. Through the threaded connection between the screw rod 35 and the housing 1, the screw rod 35 can drive the driving rack 34 to move left or right, thereby providing driving force for the movement of other components.

[0025] Working principle: When the prefabricated box-type substation is moved, the limit block 36 is moved out of the limit slot 37, and the limit block 36 is free from the limit of the box body 1. The operator rotates the screw rod 35 and the limit block 36. Through the threaded connection between the screw rod 35 and the box body 1, the screw rod 35 can drive the drive rack 34 to move left or right. When the drive rack 34 moves from left to right, the transmission shaft 31 can rotate clockwise; similarly, when the drive rack 34 moves from right to left, the transmission shaft 31 rotates counterclockwise, and the transmission shaft 31 drives the driven gear 3 After the drive rack 34 rotates clockwise, the support leg 38 can move from bottom to top, and then the roller 39 at the lower end of the support leg 38 can be retracted into the base 2; at this time, the box-type substation can be stably placed; similarly, when the driving rack 34 moves from right to left, the transmission shaft 31 rotates counterclockwise. After the transmission shaft 31 rotates counterclockwise, the support leg 38 can move from top to bottom, and then the roller 39 at the lower end of the support leg 38 can be moved out of the base 2. In this process, the box body 1 is higher than the ground, and the contact between the box body 1 and the ground changes from surface contact to rolling contact, making the substation easier to move.
