[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] Example 1:

[0024] Reference Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 A pre-installed substation deployable maintenance channel includes a base 1, to which a cabin shell 101 is fixedly connected, and further includes: an upper expansion plate 2 and a lower expansion plate 201 rotatably connected to the upper and lower ends of the cabin shell 101, wherein the cabin shell 101 is located on a side of the upper expansion plate 2 and the lower expansion plate 201 with an opening, and the inner walls on both sides of the cabin shell 101 are rotatably connected to door frames 202, and the door frames 202 are hinged with explosion-proof doors 203; a mounting plate 204 is integrally formed with the door frame 202; a sealing plate 205 is clamped between the upper expansion plate 2 and the lower expansion plate 201, and is detachably connected to the mounting plate 204; a plurality of supporting components 3 are equidistantly arranged on the lower expansion plate 201.

[0025] It also includes a plurality of fixing bolts 206 , through which the blocking plate 205 is detachably connected to the mounting plate 204 .

[0026] In specific implementation, taking a project with an 8.8-meter-long and 3.4-meter-wide cabin as an example, due to the prefabricated substation, the complete set of equipment uses a KYN61-40.5 high-voltage cabinet. The high-voltage cabinet is 2.8 meters long, and at least 1.6 meters of space needs to be reserved in front to ensure that the circuit breaker carried by the KYN61-40.5 high-voltage cabinet can be removed for maintenance. The combined length of the two is 4.4 meters. If the cabin is manufactured according to this size, normal transportation will not be possible, and transportation with this size will place higher requirements on the road environment.

[0027] In order to solve the above problems, the cabin structure can be implemented. The cabin shell 101 is made according to a width of 3 meters, and the upper expansion plate 2 and the lower expansion plate 201 are made according to a width of 1.6 meters. During transportation, the baffle plate 205 is removed, and the door frames 202 and explosion-proof doors 203 on both sides of the cabin shell 101 are retracted so that the retracted door frames 202 and explosion-proof doors 203 are located in the cabin shell 101 (such as Figure 3 、 Figure 5 As shown), the upper expansion plate 2 and the lower expansion plate 201 are folded to restore the width of the cabin shell 101 to 3 meters and consistent with the width of the transport vehicle chassis to meet the road transportation requirements. After arriving at the site, the upper expansion plate 2 and the lower expansion plate 201 are first unfolded, and then the door frames 202 on both sides of the cabin shell 101 are unfolded to enable them to quickly form an expansion structure, thereby expanding the overall internal space of the cabin shell 101 by 1.6 meters to meet the use requirements. Subsequently, the sealing plate 205 is clamped between the upper expansion plate 2 and the lower expansion plate 201, and fixed to the mounting plate 204 by fixing bolts 206, so that the expansion structure forms a closed space (as shown). Figure 1 As shown), thereby better protecting the normal operation of the high and low pressure equipment inside the cabin 101;

[0028] In summary, the expansion structure of the pre-installed substation hull 101 has the characteristics of small space occupation, flexible expansion, large expansion space, and convenient transportation when in transportation state. It effectively solves the problem of insufficient application space in the hull 101 for large high-voltage cabinets, transformers and other equipment, and avoids the impact of rainy and snowy weather on the maintenance work of the equipment built into the hull 101. The expansion structure is a confined space, which better protects the normal operation of the high and low voltage equipment inside the hull 101.

[0029] Example 2:

[0030] Reference Figure 4 、 Figure 6 , a pre-installed substation deployable maintenance channel is basically the same as Example 1, and further, a fixing ring 4 is fixedly connected to the lower expansion plate 201, and a fixing ring 2 401 is fixedly connected to the upper expansion plate 2, and the fixing ring 2 401 corresponds to the fixing ring 1 4, and a pin 402 is slidably connected to the fixing ring 1 4, and the pin 402 is inserted into the fixing ring 2 401, and a handle 403 is fixedly connected to the pin 402; it also includes a tension spring 404, which is sleeved on the pin 402, and one end of the tension spring 404 is fixedly connected to the handle 403, and the other end is fixedly connected to the fixing ring 1 4.

[0031] When the upper expansion board 2 and the lower expansion board 201 are folded and retracted (as shown in FIG. Figure 4As shown), in order to prevent the upper expansion plate 2 and the lower expansion plate 201 from being unfolded during the transportation of the cabin shell 101, the upper expansion plate 2 and the lower expansion plate 201 can be limited and fixed in the following manner:

[0032] When folding and stowing the upper expansion plate 2 and the lower expansion plate 201, first pull the handle 403 to move it to the side away from the fixed ring 4, and stretch the tension spring 404. At the same time, the handle 403 drives the pin 402 to move synchronously. Then, after the upper expansion plate 2 and the lower expansion plate 201 are folded and stowed, slowly release the handle 403, so that the handle 403 moves to the side close to the fixed ring 4 under the elastic potential energy of the tension spring 404 itself, and at the same time, the handle 403 drives the pin 402 to move synchronously until the pin 402 is inserted into the fixed ring 401 (as shown in FIG. Figure 6 As shown), the upper expansion plate 2 and the lower expansion plate 201 are limited and fixed to prevent the upper expansion plate 2 and the lower expansion plate 201 from being unfolded during transportation of the cabin shell 101, thereby improving the safety of the cabin shell 101 during transportation.

[0033] Example 3:

[0034] Reference Figure 3 、 Figure 7 , a pre-installed substation deployable maintenance channel, which is basically the same as Example 1, and further, the supporting component 3 includes a supporting tube 301 and a supporting rod 302 connected to the supporting tube 301, the supporting rod 302 is fixedly connected to the supporting seat 303, and the supporting tube 301 is fixedly connected to the lower expansion plate 201; it also includes a nut 304, the nut 304 is fixedly connected to the supporting rod 302, and the support rod 302 is threadedly connected to the supporting tube 301.

[0035] When the lower expansion board 201 is unfolded and the support base 303 is not in contact with the ground, which affects the stability of the lower expansion board 201, the stability of the lower expansion board 201 can be adjusted by the following methods:

[0036] When adjusting, a tool is required to screw the nut 304 with the tool to drive the support rod 302 to rotate. When the support rod 302 rotates, it can rotate outward from the support tube 301. At the same time, when the support rod 302 rotates outward from the support tube 301, it can drive the support seat 303 to move until the support seat 303 is tightly fitted with the ground, thereby improving the stability of the lower expansion plate 201.

[0037] Example 4:

[0038] Reference Figure 2 , a pre-installed substation deployable maintenance channel, which is basically the same as embodiment 1, further comprising a plurality of reinforcing ribs 102, the plurality of reinforcing ribs 102 being fixedly connected to the base 1 in a crisscross manner;

[0039] The provision of the plurality of reinforcing ribs 102 can effectively increase the rigidity of the base 1 , making it less likely to deform when subjected to external forces, thereby extending the service life of the base 1 .

[0040] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
