[0002] Substations are a key infrastructure in the power system, playing an important role in power conversion, distribution and protection. They are equipped with transformers, switchgear and control equipment. Substations are generally installed outdoors. In order to facilitate transportation and storage, most of them are installed in a combined manner using splicing to ensure temporary, fast and convenient installation and disassembly.

[0003] Although the traditional substation shell is a detachable splicing design, the wall shell is generally processed in an integrated manner and cannot be disassembled, which results in a relatively large area of ​​the entire side wall shell. In addition, the side walls are installed vertically, so the side walls with a large area are not convenient to lift, which makes the installation process extremely cumbersome for the staff, resulting in high installation intensity and low installation efficiency for the staff. Therefore, a spliced ​​box-type substation shell is proposed to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] See also Figure 1-7 As shown, a spliced ​​box-type substation shell includes a base 1 and a side wall shell. The base 1 has a mounting groove on its surface for mounting and supporting the side wall shell.

[0033] The side wall shell is divided into shell 1 2 and shell 2 3. A splicing mechanism is provided between shell 1 2 and shell 2 3 for splicing the two shells;

[0034] The splicing mechanism includes a groove 5, which is opened on the surface of the shell 1 2, and a mounting block 7 is fixedly connected to the surface of the shell 2 3, and the mounting block 7 is adapted to the groove 5;

[0035] A clamping groove 13 is provided on the side wall of the groove 5, and a clamping block 9 is fixedly connected to the surface of the mounting block 7;

[0036] The side wall of the groove 5 is provided with a sealing strip 16, and the surface of the mounting block 7 is provided with a sealing groove 15, and the sealing strip 16 is made of rubber;

[0037] A pressure plate 6 is movably provided on the surface of the shell 2, and a fixing bolt 8 is connected to the surface of the pressure plate 6 by a thread. A threaded hole is provided on the surface of the mounting block 7 relative to the fixing bolt 8. The pressure plate 6 is rotatably connected to the shell 2 by a torsion spring. A spring is provided on the surface of the fixing bolt 8. The horizontal height of the mounting block 7 is lower than that of the shell 2. A push plate 11 is slidably connected to the inside of the card slot 13 through an elastic member. A circular arc angle is provided on the surface of the card block 9. The elastic member is an elastic block 12. The elastic block 12 and the sealing strip 16 are both hollow. Gas is stored in the elastic block 12. The sealing strip 16 is fixed to the side wall of the groove 5. The sealing strip 16 and the elastic block 12 are connected through the air guide groove 25.

[0038] During operation, first place the base 1 in the designated position, and under the action of the torsion spring, the pressure plate 6 is in a flipped state. At this time, the mounting groove on the surface of the shell 2 3 is placed in the groove 5 and pressed downward. At this time, the block 9 will squeeze the pressure plate 6 to move downward and squeeze the elastic block 12, and squeeze the gas in the elastic block 12 to the sealing strip 16 through the air guide groove 25, so that the sealing strip 16 is pressurized and expanded, thereby improving the sealing effect between the sealing strip 16 and the sealing groove 15, preventing rain and dust from invading and protecting the substation. After the shell 2 3 is spliced ​​in place, rotate the pressure plate 6 so that the pressure plate 6 is pressed on the surface of the mounting block 7, and then press down the fixing bolt 8 and rotate it at the same time, so that the fixing bolt 8 fixes the pressure plate 6 through the thread, and then the shell 2 3 can be fixed, realizing the connection between the shell 1 2 and the shell 2 3. The splicing is then carried out, and the side wall formed by the assembly of shell 1 2 and shell 2 3 is installed on the installation groove of the base 1, and then the entire substation can be assembled. The splicable shell 1 2 and shell 2 3 can solve the problem that the area of ​​the entire side wall shell is relatively large, which is inconvenient to lift, resulting in cumbersome installation process, high installation strength and low installation efficiency, thereby greatly improving the efficiency of substation assembly. The push plate 11 driven by the elastic block 12 can block the card slot 13 when the shell 2 3 is not installed to prevent foreign objects from falling into it, thereby affecting the splicing of shell 1 2 and shell 2 3. At the same time, because the horizontal height of the mounting block 7 is lower than the horizontal height of shell 1 2, after the shell 1 2 and shell 2 3 are spliced, the fixing bolt 8 will be completely silent in the installation groove to avoid affecting the splicing and installation of the substation cover.

[0039] An air intake pipe 23 is fixedly connected to the surface of the air guide groove 25. The air intake pipe 23 passes through the elastic block 12 and is fixedly connected. A sliding shaft 18 is slidably connected to the elastic block 12 via a spring. A baffle 17 is fixedly connected to the surface of the sliding shaft 18. A rubber plug is fixedly connected to the surface of the baffle 17. A fixed block 21 is fixedly connected to the elastic block 12. A top shaft 26 is slidably connected to the surface of the fixed block 21. A slide plate 27 is fixedly connected to the surface of the top shaft 26. A pull rope 22 is fixedly connected to the surface of the slide plate 27. The end of the pull rope 22 away from the slide plate 27 is fixedly connected to the surface of the sliding shaft 18.

[0040] During operation, when the card block 9 squeezes the push plate 11, the push plate 11 is pressed down. At this time, due to the presence of the rubber plug, the gas will not enter the sealing strip 16 through the air guide groove 25, but will be continuously compressed. When the pressure plate 6 reaches the position of the top shaft 26, the pressure plate 6 squeezes the top shaft 26, causing the top shaft 26 to move downward. At this time, the top shaft 26 will drive the pull rope 22 to pull the sliding shaft 18, and the sliding shaft 18 drives the rubber plug away from the air guide tube, so that the gas is quickly filled into the sealing strip 16. The gas is temporarily retained by the rubber plug, which can avoid the card block 9 pressing down the push plate 11 while the sealing strip 16 bulges, thereby causing the mounting block 7 to scratch the sealing strip 16, causing the sealing strip 16 to lose its sealing effect. At the same time, the elastic block 12 can achieve a buffering effect to avoid collision between shell 1 2 and shell 2 3, causing damage.

[0041] Example 2

[0042] See also Figure 8 As shown, compared with Example 1, as another implementation of the present invention, indicator marks 28 are pasted on the surfaces of Shell 1 2 and Shell 2 3; during operation, the indicator marks 28 pasted on the surfaces of Shell 1 2 and Shell 2 3 can assist the staff to quickly find the direction, thereby further improving the splicing efficiency between the two shells.
