Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] The following will combine Figures 1-5 A detailed description is provided of a power distribution control device that is easy to maintain, according to an embodiment of the present invention.

[0022] Example:

[0023] This utility model provides a power distribution control device that is easy to maintain, see reference. Figures 1 to 5 As shown, the system includes a power distribution control cabinet body 1. Fixing brackets 2 are fixedly connected to the four corners of the rear inner wall of the power distribution control cabinet body 1. Equipment mounting plates 3 are bolted to the fixing brackets 2. Power distribution control electrical components 4 are mounted on the equipment mounting plates 3. Two three-section slide rails 5 are fixedly installed on the left and right inner walls of the power distribution control cabinet body 1. Connecting plates 6 are fixedly installed on the three-section slide rails 5 and are fixedly mounted on the equipment mounting plates 3. In this structure, when maintenance of the power distribution control electrical components 4 is required, personnel remove the equipment mounting plates 3 from the fixing plates 2 and pull the equipment mounting plates 3 outwards. The equipment mounting plates 3 then slide outwards via the three-section slide rails 5, thereby moving the power distribution control electrical components 4 from the outside of the power distribution control cabinet body 1. This creates more operating space for maintenance, facilitating the disassembly, assembly, and inspection of the power distribution control electrical components 4, and avoiding the inconvenience of maintenance operations due to the limited space inside the power distribution control cabinet body 1.

[0024] It should be noted that the above-mentioned three-section slide rail 5 is an existing mature accessory, and this application adopts Hettich's three-section slide rail.

[0025] refer to Figures 1 to 5As shown, the fixing frame 2 has a U-shaped structure. Nuts 7 are welded on the fixing frame 2. Through holes 8 are opened at the four corners of the equipment mounting plate 3. Connecting bolts 9 are threaded onto the nuts 7 and pass through the nuts 7. In this structure, the connecting bolts 9 pass through the through holes 8 on the equipment mounting plate 3 and are threaded onto the nuts 7 on the fixing frame 2, so that the connecting bolts 9 can connect and fix the fixing frame 2. In this way, when not in use, the position of the equipment mounting plate 3 can be fixed, thereby preventing the equipment mounting plate 3 from sliding or moving.

[0026] refer to Figures 1 to 5 As shown, two handles 10 are fixedly installed on the front side of the equipment mounting plate 3. This structure allows personnel to easily pull the equipment mounting plate 3 outward through the handles 10.

[0027] refer to Figures 1 to 5 As shown, a cable-passing tank chain 11 is fixedly installed on the lower left side of the equipment mounting plate 3. The other end of the cable-passing tank chain 11 is installed at the bottom of the inner cavity of the main body of the power distribution control cabinet 1, and the cable-passing tank chain 11 rests on the bottom of the inner cavity of the main body of the power distribution control cabinet 1. The input cable of the power distribution control electrical component 4 passes through the cable-passing tank chain 11. This structure of the cable-passing tank chain 11 facilitates the routing of the input cable of the power distribution control electrical component 4, thereby ensuring that the input cable of the built-in power distribution control electrical component 4 can be stored, pulled and protected when the equipment mounting plate 3 moves.

[0028] refer to Figures 1 to 5 As shown, a cable-passing tank chain 12 is fixedly installed on the lower left side of the equipment mounting plate 3. The other end of the cable-passing tank chain 12 is installed at the bottom of the inner cavity of the main body of the power distribution control cabinet 1, and the cable-passing tank chain 12 rests on the bottom of the inner cavity of the main body of the power distribution control cabinet 1. The output cable of the power distribution control electrical component 4 passes through the cable-passing tank chain 12. This structure facilitates the routing of the output cable of the power distribution control electrical component 4, thereby ensuring that the output cable of the built-in power distribution control electrical component 4 can be stored, pulled and protected when the equipment mounting plate 3 moves.

[0029] refer to Figures 1 to 5 As shown, the power distribution control electrical component 4 includes an incoming switch, a circuit breaker, a fuse, a contactor, a fuse wire, and a connecting circuit.

[0030] refer to Figures 1 to 5 As shown, the front of the main body 1 of the power distribution control cabinet is hinged with a cabinet door 13. This structure allows the cabinet door 13 to be easily opened by personnel, thus facilitating maintenance work.

[0031] The implementation principle of a maintenance-friendly power distribution control device according to an embodiment of this application is as follows: When it is needed to maintain the power distribution control electrical component 4, the personnel remove the equipment mounting plate 3 from the fixing plate 2, and then pull the equipment mounting plate 3 outward. At this time, the equipment mounting plate 3 slides outward through the three-section slide rail 5, thereby moving the power distribution control electrical component 4 on the entire equipment mounting plate 3 to the outside of the power distribution control cabinet body 1, thus creating more operating space for maintenance, making it convenient for personnel to disassemble and inspect the power distribution control electrical component 4, and avoiding the inconvenience of personnel to perform maintenance operations due to the small space inside the power distribution control cabinet body 1.

[0032] After maintenance is completed, personnel push the equipment mounting plate 3 from inside the box, and then push the equipment mounting plate 3 inward until it abuts against the fixing frame 2. Then, personnel thread the connecting bolt 9 through the through hole 8 on the equipment mounting plate 3 and thread it with the nut 7 on the fixing frame 2. This allows the connecting bolt 9 to connect and fix the fixing frame 2, thereby fixing the position of the equipment mounting plate 3 and preventing it from sliding or moving.
