In order to complete the transportation smoothly, the existing method usually splits each component of the box -type substation, is transported to the scene respectively and then is assembled. This process involves the on -the -spot combination of wall body, base and top cover and multiple components. Although this split assembly mode solves the transportation difficulty to some extent, still exposes many problems in actual operation. The existing substation shell usually adopts the welding mode in the assembly process, and this method not only makes the installation process complex, but also leads to difficulty in disassembly. Due to the solidification characteristics of the welding connection, any operation needing disassembly or replacement needs additional cutting and welding operation, increasing the labor and time cost.

[0003] The patent with the publication number CN222191549U discloses a splicing box -type substation shell, which comprises a base, the bottom of the base is fixedly connected with an anti -skid block, the top of the base is fixedly connected with an electric telescopic rod, the top of the electric telescopic rod is fixedly connected with a lifting rod, the top of the lifting rod is fixedly connected with a stable cover, the top of the stable cover is fixedly connected with a shell seat, the inside of the shell seat is installed with a first shell body and a second shell body, the outer side of the second shell body is fixedly connected with a compression spring, the outer side of the compression spring is fixedly connected with a clamping plate, the inner top wall of the first shell body is provided with a through -hole, the inside of the clamping plate is provided with a positioning hole, the utility model has the advantages of simple structure, convenient to use, convenient for the assembly and disassembly of the box -type substation shell, and can adjust the height of the shell bottom to prevent the bottom from being humid.

[0004] The prior art box-type substation shell after assembly, because the first shell and the second shell are not effectively fixed with the shell seat, resulting in instability of the overall structure. In actual use, the shell is prone to displacement when facing wind pressure, vibration and other external forces, and even may lead to the risk of collapse. In addition, the stable rod at the bottom of the cover plate enters the positioning hole in the clamping plate through the insertion hole, so that the positions of the first shell and the second shell are fixed, but this connection structure cannot ensure the effective connection between the first shell, the second shell and the cover plate. Especially in windy weather, the cover plate is easily lifted by wind force, resulting in the loss of protection function of the shell, and further affecting the safety of the internal equipment of the substation. Therefore, this prior art box-type substation shell has significant safety hazards and stability problems in use, and needs to be improved to improve its overall performance and reliability.
