[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5This utility model provides an embodiment of a power distribution control device that is easy to maintain, including a control cabinet 1. Multiple mounting brackets 101 are fixedly connected to the rear end face of the control cabinet 1. Each mounting bracket 101 has two support brackets 2 connected to its front end. A connecting plate 206 is fixedly connected to the rear end of each support bracket 2. The connecting plate 206 is fixedly connected to the mounting bracket 101 by bolts. Linear guide rails 205 are fixedly connected to both sides of the upper middle portion of each support bracket 2. A mounting plate 3 is connected to the upper end of both linear guide rails 205. Slider blocks 301 are fixedly connected to both sides of the lower middle portion of the mounting plate 3. The two sliders 301 at the lower end of the plate 3 are slidably connected to the two linear guide rails 205 at the upper end of the bracket 2, so that the two sliders 301 can slide on the linear guide rails 205, thereby allowing the mounting plate 3 to slide forward through the two sliders 301. The upper end of the mounting plate 3 is fixedly connected to the control component 4. During maintenance, after the personnel open the door of the control cabinet 1, they can pull the control component 4 to make the mounting plate 3 slide forward through the sliders 301, so that the control component 4 can be pulled out of the control cabinet 1, making it convenient for personnel to repair and disassemble the control component 4.

[0025] The mounting plate 3 and the control component 4 are fixedly connected by bolts. Personnel can detach the control component 4 from the mounting plate 3 by removing the bolts connecting the mounting plate 3 and the control component 4, facilitating the installation and removal of the control component 4. A telescopic groove 201 is provided in the middle of the bracket 2, and a telescopic rod 202 is provided inside the telescopic groove 201. A limit disc 203 is fixedly connected to the rear end of the telescopic rod 202. A spring 204 is provided on the outer side of the telescopic rod 202 at the front end of the limit disc 203. A linkage plate 302 is fixedly connected to the front end of the mounting plate 3. The front end of the telescopic rod 202 extends out of the front end face of the bracket 2 and is fixedly connected to the rear end face of the linkage plate 302. When personnel pull... When the control component 4 moves forward and drives the mounting plate 3 to move, the telescopic rod 202 extends forward through the linkage plate 302 at the front end of the mounting plate 3. This causes the limiting disc 203 to move forward and compress the spring 204. When the control component 4 is released from the outward pulling state, the operator pushes the control component 4 back into the control cabinet 1. The spring 204 pushes the limiting disc 203 to move, causing the limiting disc 203 to drive the telescopic rod 202 back into the telescopic groove 201. This assists in pulling the mounting plate 3 back to its original position. At the same time, the spring 204 keeps the telescopic rod 202 in the telescopic groove 201, ensuring that the mounting plate 3 remains stable and does not slide after the control component 4 is back into the control cabinet 1.

[0026] Working Principle: During normal operation, the control component 4 is securely fixed to the mounting plate 3 with bolts. The mounting plate 3 is then stably installed inside the control cabinet 1 via a sliding connection of the slider 301 on the linear guide rail 205. This design ensures that the control component 4 remains securely inside the control cabinet 1 when maintenance is not required, guaranteeing the stable operation of the power system. When maintenance is needed, the operator simply opens the door of the control cabinet 1 and gently pulls the control component 4. Due to the sliding connection between the mounting plate 3, the slider 301, and the linear guide rail 205, the control component 4 easily slides forward along the linear guide rail 205. During this process, the linkage plate 302 at the front end of the mounting plate 3 pushes the telescopic rod 202 forward within the telescopic groove 201, while the spring 204 is compressed. This design not only facilitates the easy pulling out of the control component 4, but also provides auxiliary force for its retraction through the elastic force of the spring 204. Once the control component 4 is pulled to a position convenient for maintenance, the operator can easily remove the bolts between the control component 4 and the mounting plate 3, separating the control component 4 from the mounting plate 3 for maintenance or replacement. This design greatly improves the efficiency and convenience of maintenance work, eliminating the need for cumbersome operations within the confined space of the control cabinet 1. After maintenance, the operator simply reinstalls the control component 4 onto the mounting plate 3 and pushes it to slide the mounting plate 3 backward along the linear guide 205 back into the control cabinet 1. At this point, the spring 204 uses its own elastic force to push the limit disc 203 and the telescopic rod 202 back to their original positions, ensuring that the mounting plate 3 remains stable inside the control cabinet 1 and does not slide on its own. This design not only improves the reliability and safety of the equipment but also ensures the stable operation of the power system.
