A spliced box-type substation shell

Abstract

This utility model relates to the field of prefabricated substation enclosure technology, and provides a modular prefabricated substation enclosure, including a base and a splicing mechanism. The splicing mechanism is provided on one side of the surface of the base. The modular prefabricated substation enclosure provided by this solution first moves the base to a suitable position, then inserts four sets of right-angle side plates and corresponding horizontal and vertical plates into slots. Multiple sets of wedges are then inserted into corresponding trapezoidal grooves, quickly connecting the horizontal and right-angle side plates, and the vertical and right-angle side plates, thus completing the enclosure. Subsequently, fixing bolts are used to quickly connect the whole formed by the right-angle side plates, horizontal plates, and vertical plates to the base. Then, pressing the limiting block causes it to enter the integrated groove under the action of a spring, embedding the extension end of the top cover into the sliding groove. When the limiting groove and the integrated groove are aligned, the limiting block will enter the limiting groove, locking the top cover in place, thus completing the splicing installation.

Its extension end is provided with an integrated groove 215 and a limiting block 217 to realize the limiting and buffering functions, which are used to cover and stabilize the top of the splicing structure, prevent the parts from falling off, and enhance the sealing and stability of the overall structure.

[0044] In summary, first, the base 1 is moved to a suitable position. Then, the four sets of right-angle side plates 204 and the corresponding horizontal plates 205 and vertical plates 206 are inserted into the slots 201 respectively. Multiple sets of wedges 211 are embedded into the corresponding trapezoidal slots 208, thereby quickly connecting the horizontal plates 205 and right-angle side plates 204, and the vertical plates 206 and right-angle side plates 204, thus completing the enclosure. Afterwards, the fixing bolts 207 are used to quickly connect the whole formed by the right-angle side plates 204, horizontal plates 205 and vertical plates 206 to the base 1. Then, the limiting block 217 is pressed. Under the action of the spring 216, the limiting block 217 enters the integrated groove 215 and embeds the extension end of the top cover 213 into the sliding groove 212. When the positions of the limiting groove 214 and the integrated groove 215 are aligned, the limiting block 217 will enter the limiting groove 214, that is, the top cover 213 will be engaged, thus completing the splicing and installation work.
