[0029] Embodiment 1:

[0030] This embodiment provides a modular replaceable box-type substation, such as Figure 1-7 As shown, the box-type substation body 1 includes a box body 101 and a box cover 102, wherein the box body 101 is a square shell structure, and the box cover 102 is detachably installed on the top of the box body 101, preferably detachably buckled on the upper part of the box body 101 by bolts; to meet the necessary disassembly and assembly requirements; Figure 2As shown; a low-voltage chamber partition 2 and a high-voltage chamber partition 3 are arranged in the main body 1 of the box-type substation, and the main body 1 of the box-type substation, that is, the main body 101 of the box-type substation is divided into a low-voltage chamber 4, a transformer chamber 5 and a high-voltage chamber 6; a cabinet consisting of a low-voltage incoming line cabinet, a low-voltage outgoing line cabinet and a low-voltage capacitor cabinet is installed in the low-voltage chamber 4; an integrated cabinet such as a high-voltage incoming line cabinet and a high-voltage outgoing line cabinet is installed in the high-voltage chamber 6. When the whole is assembled in the workshop, the cabinet is usually hoisted as a whole into the corresponding room; a low-voltage chamber door 9 and a transformer chamber door are installed on the main body 1 of the box-type substation corresponding to the low-voltage chamber 4, the transformer chamber 5 and the high-voltage chamber 6, respectively 10 and high-voltage chamber door 11; wherein, a displacement stage group 7 is slidably installed in the low-voltage chamber 4 and the high-voltage chamber 6 respectively. The displacement stage group 7 serves as a cabinet installation platform installed indoors, and can enter and exit the box body 101 from the low-voltage chamber door 9 or the high-voltage chamber door 11, so that the cabinet installed on the displacement stage group 7 can be pushed into or pushed out of the box body 101; to solve the problem of hoisting, an auxiliary support mechanism 8 is also provided on the displacement stage group 7. The auxiliary support mechanism 8 serves as a support mechanism when the displacement stage group 7 is pushed out, and serves as a front support leg, and together with the rear box body 101, it serves as a support structure.

[0031] As one specific implementation method, Figure 3-7As shown, the displacement platform group 7 includes a displacement guide rail 71, a displacement mounting platform 72 and a displacement screw assembly 73; the displacement guide rail 71 is fixedly installed in the box-type substation body 1, that is, it is installed on the box body 101 at the bottom of the low-voltage chamber 4 and the high-voltage chamber 6, and its axial direction is perpendicular to the direction of the box door; the displacement mounting platform 72 is slidably connected to the displacement guide rail 71, and the displacement mounting platform 72 and the displacement guide rail 71 are connected by guide rails to realize the sliding movement of the displacement mounting platform 72; at the same time, the displacement mounting platform 72 is used as an installation platform for a cabinet or equipment instead of being directly installed in the box body 101, and a displacement screw assembly 73 is arranged at the lower part of the displacement mounting platform 72. The displacement screw assembly 73 serves as a power drive mechanism, and one end of the displacement screw assembly 73 is abutted and connected to the box-type substation body 1, or abutted and connected to the lower part of the low-voltage chamber partition 2 or the high-voltage chamber partition 3, so as to drive the displacement mounting platform 72 to slide; the displacement mounting platform 72 is pushed out or pushed in by means of a screw drive; specifically: the displacement screw The rod assembly 73 includes a displacement thread block 731, a displacement screw 732 and an extended rotating rod 733. The displacement thread block 731 is fixedly mounted on the lower part of the displacement mounting platform 72. The displacement thread block 731 is preferably mounted on the displacement mounting platform 72 near the side of the low-voltage chamber partition 2 or the high-voltage chamber partition 3, so as to ensure that the displacement mounting platform 72 has a sufficient displacement distance; the displacement thread block 731 is threadedly connected to the displacement screw 732, and the displacement screw 732 is rotatably mounted in the box-type substation body 1 below the displacement mounting platform 72; the extended rotating rod 733 is detachably connected to one end of the displacement screw 732, that is, the end near the box door, and the rotation of the extended rotating rod 733 drives the displacement screw 732 to rotate, thereby realizing the transmission movement of the ball screw structure; finally, the sliding movement of the displacement mounting platform 72 is realized. In normal working state, the extended rotating rod 733 and the displacement screw 732 are in a non-connected state. When the displacement mounting platform 72 needs to be pushed out or pushed in, the extended rotating rod 733 needs to be connected to the displacement screw 732.

[0032] like Figure 4 As shown, the auxiliary support mechanism 8 includes a support adjustment rod 81 and a support wheel 82. The support adjustment rod 81 is threadedly connected to the displacement mounting platform 72. The threaded connection of the support adjustment rod 81 can facilitate support and storage to meet different height support requirements. The support wheel 82 is installed at the lower part of the support adjustment rod 81. The support wheel 82 is preferably a universal wheel. When the displacement mounting platform 72 is extended from the cabinet door, it is supported by the ground.

[0033] Furthermore, in order to facilitate the installation of the transformer in the transformer chamber 5 , a displacement stage group 7 is also provided in the transformer chamber 5 .

[0034] The working principle of the utility model is as follows: first, when outdoor maintenance and replacement is required, the line connection structure between the module to be replaced and other chambers is first disconnected, the extension rotating rod 733 is installed to connect the displacement screw 732, and the extension rotating rod 733 is rotated to drive the displacement screw 732 to rotate, thereby pushing out the displacement mounting platform 72. When the outer end of the displacement mounting platform 72 is pushed out of the door, the auxiliary support mechanism 8 is supported in time, and the support adjustment rod 81 is adjusted to make the support wheel 82 reliably support the ground; then the displacement screw assembly 73 continues to push out the displacement mounting platform 72 to carry out the hoisting work of the cabinet. After the hoisting position is adjusted, the displacement screw assembly 73 is operated in reverse to screw it into the corresponding low-pressure chamber 4 or high-pressure chamber 6.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields.
