Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes a modular aging cabinet power supply panel, including a cabinet 1. Three support frames 2 are fixedly connected inside the cabinet 1, and eight output low-voltage modules 3 are inserted into each of the three support frames 2. Each support frame 2 has a limiting mechanism 4 on its front side wall for limiting the output low-voltage modules 3. A mounting frame 5 is fixedly connected to the rear end of the support frame 2, and hot-swappable terminals 6 corresponding to the output low-voltage modules 3 are respectively installed on the mounting frame 5. A control unit 7 is fixedly connected to the inner top wall of the cabinet 1.

Two sets of modular load circuit breakers 12 are evenly installed on the front side wall of the mounting plate 11. The bottom of the cabinet 1 is equipped with a retractable and movable mechanism 13. Hot-swappable terminals 6 facilitate quick plug-and-play connection of the output low-voltage module 3 without the need for wiring connections, improving the efficiency of installation and replacement. Indicator lights 8 are used to display the working status of the equipment. A display screen 9 is installed in the center to display the operating parameters and fault information of the equipment. The connection and control methods of the modular output circuit breakers 10 and the modular load circuit breakers 12 with other components are existing technologies and will not be described in detail here. The retractable and movable mechanism 13 facilitates the movement of the equipment.

[0018] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the limiting mechanism 4 further includes an assembly plate 401 fixed to the front side wall of the support frame 2 by screws. Two fixing ears 402 are symmetrically and fixedly connected to the assembly plate 401. A slide rod 403 is slidably connected between the two fixing ears 402. A limiting seat 404 is fixedly connected to the top end of the slide rod 403. Two connecting pieces 405 are fixedly connected to the slide rod 403. A spring 406 is sleeved on the slide rod 403. The two ends of the spring 406 are respectively fixedly connected to the upper fixing ear 402 and the upper connecting piece 405. A rotating sleeve 407 is provided between the two connecting pieces 405. The rotating sleeve 407 is rotatably connected to the slide rod 403. A bracket 408 is fixedly connected between each fixed ear 402. A movable opening 409 is provided on the bracket 408. A toggle pin 4010 is provided in the movable opening 409. The bottom end of the toggle pin 4010 is fixedly connected to the rotating sleeve 407. A limit piece 4011 is fixedly connected to the end of the slide rod 403 away from the limit seat 404. When it is necessary to install or remove the output low voltage module 3, the toggle pin 4010 is moved to drive the rotating sleeve 407 to rotate, so that the toggle pin 4010 enters the vertical opening of the movable opening 409. The spring 406 returns to its original shape and pushes the upper connecting piece 405 to move, thereby moving the slide rod 403, which in turn moves the limit seat 404 downward, thereby releasing the limit on the output low voltage module 3.

[0019] like Figure 1 , Figure 2 and Figure 5As shown, in a preferred embodiment, based on the above method, the retractable movable mechanism 13 further includes a bottom frame 1301 fixed to the bottom of the cabinet 1. A bidirectional screw 1302 is rotatably connected inside the bottom frame 1301. Two movable blocks 1303 are symmetrically and threadedly connected to the bidirectional screw 1302. Guide rods 1304 are slidably connected to both ends of the two movable blocks 1303. The two ends of the guide rods 1304 are respectively fixedly connected to the left and right inner sidewalls of the bottom frame 1301. Two connecting rods 1305 are rotatably connected to both movable blocks 1303. A connecting block 1306 is rotatably connected to the bottom end of the connecting rod 1305. A lifting plate 1307 is fixedly connected to the bottom end of the connecting block 1306. The four corners of the lower end face of the lifting plate 1307 are... All parts are fixedly connected with casters 1308. One end of the bidirectional screw 1302 passes through the side wall of the bottom frame 1301 and is fixedly connected with a handwheel 1309. When the equipment needs to be moved, turn the handwheel 1309 to rotate the bidirectional screw 1302, and the two moving blocks 1303 move inward at the same time. Through the connecting rod 1305, the lifting plate 1307 is pushed down, the casters 1308 contact the ground, and the equipment is lifted up. At this time, the equipment can be moved easily. After moving to the designated position, turn the handwheel 1309 in the opposite direction, the bidirectional screw 1302 rotates in the opposite direction, the two moving blocks 1303 move in opposite directions, and through the connecting rod 1305, the lifting plate 1307 is pulled up, the casters 1308 leave the ground, and the bottom of the equipment contacts the ground, thus fixing the equipment.

[0020] like Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the lifting plate 1307 is further slidably connected to the bottom frame 1301, and protrusions 1310 are fixedly connected to both the left and right ends of the lifting plate 1307. Limiting openings 1311 that cooperate with the protrusions 1310 are provided on both the left and right side walls of the bottom frame 1301. The protrusions 1310 and the limiting openings 1311 cooperate to ensure the stability of the lifting plate 1307 during the lifting process.

[0021] like Figure 1 and Figure 6 As shown, in a preferred embodiment, based on the above method, the cabinet 1 is further connected to a cabinet door 14 via a hinge. A transparent panel 15 is installed on the upper side of the cabinet door 14. A set of heat dissipation vents are evenly opened on the cabinet door 14, and a filter screen 16 is fixedly connected inside the heat dissipation vents. The transparent panel 15 allows for convenient observation of the working status of the equipment inside the cabinet 1 without opening the cabinet door 14. The filter screen 16 is used for heat dissipation during equipment operation to ensure that the equipment operates at a suitable temperature. The filter screen 16 can prevent dust and other debris from entering the cabinet 1 and protect the internal equipment.

[0022] like Figure 3As shown, in a preferred embodiment, based on the above method, further, guide strips 17 that cooperate with the output low-voltage module 3 are fixedly connected at equal intervals inside the support frame 2, and a set of through holes 18 are evenly opened at the bottom of the support frame 2; the guide strips 17 provide a guiding function for the insertion of the output low-voltage module 3, so that the output low-voltage module 3 can be accurately and smoothly inserted into the support frame 2, while ensuring the installation stability of the output low-voltage module 3 inside the support frame 2.

[0023] Specifically, when using this modular aging cabinet power supply panel: If the output low-voltage module 3 needs to be replaced, move the lever 4010 to rotate the rotating sleeve 407, causing the lever 4010 to enter the vertical opening of the movable opening 409. The spring 406 returns to its original shape, pushing the upper connecting piece 405 to move, thereby moving the slide rod 403 and causing the limit seat 404 to move downwards, thus releasing the limit on the output low-voltage module 3. Then, pull the output low-voltage module 3 outwards to separate it from the hot-swappable terminal 6. Remove it and then install the new output low-voltage module 3 into the carrier frame 2, ensuring its interface end engages with the hot-swappable terminal 6. Then, hold the lever 4010 to move the rotating sleeve 407, thereby pushing the slide rod 403 and the limit seat 404 upwards to limit the output low-voltage module 3. When the spring 406 is compressed, the lever 4010 moves to the top of the moving opening 409 and then rotates to the lateral limit position of the moving opening 409, thereby limiting the position of the limit seat 404. When the equipment needs to be moved, the handwheel 1309 is turned to rotate the bidirectional screw 1302, and the two moving blocks 1303 move inward at the same time. The lifting plate 1307 is pushed down through the connecting rod 1305, and the caster wheel 1308 contacts the ground, lifting the equipment. At this time, the equipment can be moved easily. After moving to the designated position, the handwheel 1309 is turned in the opposite direction, the bidirectional screw 1302 rotates in the opposite direction, and the two moving blocks 1303 move in opposite directions. The lifting plate 1307 is pulled up through the connecting rod 1305, the caster wheel 1308 leaves the ground, and the bottom of the equipment contacts the ground, thus fixing the equipment.

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
