Power generation equipment mainly includes power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, instrument transformers, contactors, etc. In railway transportation engineering, when electrical equipment is damaged, engineers need to arrive on site in a timely manner to inspect and repair it.

[0003] A search of publication number "CN221885865U" reveals "a power equipment maintenance device for railway power supply sections, comprising a housing, an internal placement mechanism for power equipment maintenance, and an external sealing component to improve the housing's sealing performance. The placement mechanism allows users to easily move the housing and placement mechanism to a suitable position, fix the placement mechanism, and then remove the power equipment for maintenance, placing it on the placement mechanism for further inspection. This improves convenience and efficiency. The sealing component ensures the housing is sealed when moved, preventing the loss of internal parts. Furthermore, the combined use of the housing and sealing component allows for the carrying of maintenance tools, further enhancing convenience." The aforementioned patent requires manual operation to open the casing when inspecting power equipment, then remove the maintenance tools inside the casing before proceeding with the maintenance.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] See attached document Figure 1-5 A maintenance device for railway power supply includes a mounting shell 1. One end of the mounting shell 1 has a movable groove 6. A lead screw 10 is rotatably connected between the upper and lower inner walls of the movable groove 6. A lead screw nut 11 is threaded onto the circumferential surface of the lead screw 10. The two ends of the mounting shell 1 have the movable groove 6 and the sliding groove 15, respectively. One end of the lead screw nut 11 is fixedly connected to a placement shell 13. One end of the placement shell 13 is fixedly connected to a sliding block 16. The sliding block 16 is slidably connected in the sliding groove 15. The far ends of the lead screw nut 11 and the sliding block 16 are rotatably connected to a pull rod 5 through a rotating shaft. The near ends of the two pull rods 5 are fixedly connected to a sealing plate 3.

[0022] In a specific embodiment of this utility model, when the power supply equipment needs to be repaired, the lead screw 10 is rotated so that the lead screw nut 11 connected to the circumferential surface moves in the moving groove 6. During this process, the lead screw nut 11 drives the placement shell 13 to move synchronously, and then drives the sliding block 16 to slide in the sliding groove 15. When the lead screw nut 11 and the sliding block 16 move synchronously, the two sealing plates 3 are pulled away from each other by the two pulling rods 5. After the two sealing plates 3 are separated to the maximum extent, the placement shell 13 will rise to the highest end of the mounting shell 1. At this time, personnel can easily take out the tools in the placement shell 13, which is convenient for subsequent maintenance of the power supply equipment.

[0023] Please refer to the details. Figure 1-5 Two racks 7 are fixed to one end of each of the two sealing plates 3. Two gears 22 are rotatably connected to one end of the mounting shell 1 via a rotating shaft. The two gears 22 mesh with the two racks 7 respectively. A rotating disk 21 is fixedly connected to one end of each of the two rotating shafts. A handle 4 is fixedly connected to the circumferential surface of each of the two rotating disks 21.

[0024] In this embodiment: when the sealing plate 3 is closed, the mounting shell 1 and multiple components can be conveniently carried by the two handles 4. As the two sealing plates 3 gradually move towards the separation end, the two sealing plates 3 drive the two racks 7 to move towards the farthest ends. Then, the two racks 7 drive the two meshing gears 22 and the rotating shaft to rotate. Then, the two handles 4 are straight, so that the two handles 4 will not hinder the user from picking up the tools.

[0025] Please refer to the details. Figure 1-5 Both handles 4 are fixedly connected to anti-slip sleeves 23 on their circumferential surfaces. Multiple foot pads 2 are fixedly connected to the lower end of the mounting shell 1. A vertical rod 24 is fixedly connected between the upper and lower inner walls of the moving groove 6. A vertical hole is opened at the upper end of the lead screw nut 11, and the lead screw nut 11 is slidably connected to the circumferential surface of the vertical rod 24 through the vertical hole.

[0026] In this embodiment: two anti-slip sleeves 23 make it easier for users to hold the handle 4 more stably, multiple foot pads 2 improve the stability of the mounting shell 1 when placed on the ground, and when the lead screw nut 11 moves, it can slide on the circumferential surface of the vertical rod 24 through the vertical hole, thereby improving the vertical movement stability of the lead screw nut 11.

[0027] Please refer to the details. Figure 1-5 The lower inner wall of the moving groove 6 is provided with an installation groove, and a motor 12 is fixedly connected in the installation groove. The output end of the motor 12 is fixedly connected to the moving groove 6. A stabilizing strip 14 is fixedly connected to one side inner wall of the mounting shell 1. A stabilizing groove is provided at the upper end of the placement shell 13, and the placement shell 13 is slidably connected to the outer surface of the stabilizing strip 14 through the stabilizing groove.

[0028] In this embodiment: the rotation of the output shaft of the motor 12 fixedly connected in the mounting slot can automatically drive the rotation of the lead screw 10. When the placement shell 13 moves vertically, it can slide on the outer surface of the stabilizing bar 14 through the stabilizing groove, thereby improving the vertical movement stability of the placement shell 13.

[0029] Please refer to the details. Figure 1-5 Two sealing plates 3 are respectively fixedly connected to a locking shell 8 and a locking strip 9 at their close ends. The locking shell 8 and the locking strip 9 are locked together. Multiple stabilizing grooves 17 are provided at the upper end of the mounting shell 1. Two stabilizing blocks 18 are fixedly connected to the lower ends of the two sealing plates 3. The multiple stabilizing blocks 18 are slidably connected to the multiple stabilizing grooves 17. Anti-detachment grooves 19 are provided on one side of the inner wall of the multiple stabilizing grooves 17. Anti-detachment blocks 20 are fixedly connected to one end of the multiple stabilizing blocks 18. The multiple anti-detachment blocks 20 are slidably connected to the multiple anti-detachment grooves 19.

[0030] In this embodiment: After the two sealing plates 3 are connected, the locking strip 9 can be inserted into the locking shell 8 to improve the locking tightness of the two sealing plates 3. When the two sealing plates 3 move horizontally, the stabilizing block 18 and the anti-detachment block 20 will slide in the stabilizing groove 17 and the anti-detachment groove 19 respectively, thereby improving the horizontal movement stability of the two sealing plates 3.

[0031] Working principle: When the power supply equipment needs to be repaired, the lead screw 10 is rotated so that the lead screw nut 11 connected to its circumferential surface moves in the moving groove 6. During this process, the lead screw nut 11 drives the placement shell 13 to move synchronously, and then drives the sliding block 16 to slide in the sliding groove 15. When the lead screw nut 11 and the sliding block 16 move synchronously, the two sealing plates 3 are pulled away from each other by the two pull rods 5. After the two sealing plates 3 are separated to the maximum extent, the placement shell 13 will rise to the highest end of the mounting shell 1. At this time, personnel can easily take out the tools in the placement shell 13, which is convenient for subsequent maintenance of the power supply equipment.
