Description

Technical Field

[0001] This application relates to the field of power distribution cabinet technology, and more specifically, to a power distribution cabinet maintenance device that is easy to inspect and repair. Background Technology

[0002] A distribution cabinet is the final stage equipment in a power distribution system. It distributes power through a large number of electrical components installed inside the cabinet. When the internal parts or lines of the distribution cabinet are damaged, maintenance and repair are required.

[0003] The existing technology announcement CN214124379U provides a power distribution cabinet that is easy to maintain, facilitating localized maintenance and easy disassembly, thus enhancing practicality and improving reliability. It includes a power distribution cabinet body, wiring sockets, drawer front panels, drawer frames, drawer handles, screw shafts, screw handles, locking rings, pins, pin frames, electronic components, a controller, a touch screen, slide rails, and plugs. The lower front of the power distribution cabinet body has several sets of drawer slots. Each set of drawer slots has a set of slide rails on the left and right sides of its bottom. The output end of the locking ring is connected to the input end of the screw shaft. The middle of the top front of the drawer slot is connected to the top of the pin frame. Electronic components are installed inside the drawer frame. The upper front of the power distribution cabinet body is connected to the inner end of the controller. The output end of the controller is connected to the equipment control system. The upper outer end of the controller is connected to the inner end of the touch screen. The left and right sides of the bottom of the drawer frame are connected to the top of a set of slide rails. The middle rear end of the drawer frame is connected to the inner end of the plug.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks:

[0005] Using multiple independent drawers to install electrical components means that only one drawer can be pulled out at a time for maintenance, which is not conducive to the overall observation of electrical components. As a result, after maintaining the electrical components in one drawer, it may be found that there is still a problem with the circuit, and it is necessary to pull out the previous drawer again for inspection. This is not conducive to the overall maintenance of the circuit and the identification of the problem.

[0006] Regarding the aforementioned related technologies, the inventor believes that installing electrical components using multiple independent drawers means that only one drawer can be pulled out for maintenance at a time, which is not conducive to the overall observation of the electrical components. As a result, after maintaining the electrical components in one drawer, it may be found that there is still a problem with the circuit, and it may be necessary to pull out the previous drawer again for inspection, which is not conducive to the overall maintenance of the circuit and the identification of problem points.

[0007] In view of this, we propose a power distribution cabinet maintenance device that is easy to inspect and repair. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The purpose of this application is to provide a power distribution cabinet maintenance device that is easy to inspect and repair. It solves the technical problem in the above-mentioned background technology where electrical components are installed in multiple independent drawers. When maintenance is performed, only one drawer can be pulled out at a time, which is not conducive to the observation of the overall electrical components. As a result, after maintaining the electrical components in one drawer, it is found that there is still a problem in the circuit, and it is necessary to pull out the previous drawer again for inspection. This is not conducive to the overall maintenance of the circuit and the identification of the problem point. The application achieves the desired technical effect.

[0010] 2. Technical Solution

[0011] This application provides a maintenance device for a power distribution cabinet that is easy to inspect and repair, comprising:

[0012] The cabinet has a door opening on one side;

[0013] A hinged door is provided at the doorway.

[0014] A movable rack is provided inside the cabinet.

[0015] Mounting plates, and multiple mounting plates are fixedly mounted on the movable frame;

[0016] A moving mechanism is installed between the bottom of the moving frame and the cabinet.

[0017] A wiring mechanism is installed between the movable frame, the mounting plate, and the cabinet.

[0018] With the above solution, electrical components are bolted to the mounting plate, and the wiring of the electrical components is integrated through a wiring mechanism. The movable frame can be pulled out or pushed into the cabinet through the moving mechanism, which facilitates the observation and maintenance of the electrical components after they are pulled out as a whole, thus improving the convenience of maintenance.

[0019] Optionally, the moving mechanism includes a fixed plate, two pairs of fixed plates are fixedly installed on both sides of the bottom of the moving frame, fixed wheels are rotatably installed between the bottom inner walls of the fixed plates, a fixed block is fixedly installed at the bottom of the moving frame near the opening and closing door, fixed shafts are fixedly installed on both sides of the fixed block, a rotating plate is rotatably sleeved on the fixed shaft, movable wheels are installed between the inner walls of the rotating plate, a limiting plate is fixedly installed at the bottom of the moving frame on the side of the fixed block near the fixed plate, the limiting plate movably fits against one side of the rotating plate, a connecting plate is fixedly installed on the other side of the rotating plate, a spring is installed between the connecting plate and the bottom of the moving frame, the spring is always in a compressed state, a torsion spring is installed between the rotating plate and the fixed shaft, a support block is fixedly installed at the bottom of the inner cavity of the cabinet, the support block movably fits against the bottom of the moving frame, a sliding groove is opened on the support block, a slider is fixedly installed at the bottom of the moving frame, the slider slides into the sliding groove, and the cross-section of the slider and the sliding groove is a matching T-shaped structure.

[0020] With the above scheme, when the movable frame is pulled out, the movable wheel is pulled out of the cabinet first. At this time, the elastic force of the torsion spring and the spring causes the rotating plate to rotate and fit against the limiting plate. The rotating plate is in a vertical state, and the movable wheel rolls against the ground. When pulled out, the rolling of the movable wheel applies a force to the rotating plate to turn towards the limiting plate, so that the rotating plate fits against the limiting plate and remains in the limit position, thus providing stable support for the part of the movable frame when it is pulled out. The slider and the slide groove cooperate to prevent the movable frame from being completely pulled out. At this time, it is convenient to maintain the overall electrical components. When the movable frame is pushed into the cabinet, the fixed wheel supports the movable frame, and the movable wheel is pushed when it moves to the bottom plate of the cabinet, so that the rotating plate overcomes the elastic force of the spring and the torsion spring and rotates away from the limiting plate, thus facilitating the movable wheel to enter the cabinet and realizing the pushing in of the movable frame.

[0021] Optionally, the wiring mechanism includes a cable tray, with the cable tray fixedly installed on the side of the movable frame and mounting plate away from the door opening. The mounting plate has a through hole connecting the cable tray. A main cable is fixedly installed between the cable tray and the inner wall of the cabinet. Multiple elastic clips are fixedly installed on the inner wall of the cable tray. The main cable has an elastic spiral structure, the elastic clips have a C-shaped structure, and the door opening and the hinged door have a matching "L"-shaped structure.

[0022] With the above scheme, the electrical wiring on the mounting plate enters the wire groove through the through holes and is snapped together by elastic clips, which facilitates the connection of wiring between electrical components. The main line adopts an elastic spiral structure, so that it automatically extends and retracts when the moving frame is pushed in and pulled out.

[0023] 3. Beneficial effects

[0024] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0025] 1. In this application, when the movable frame is pulled out, the movable wheel is pulled out of the cabinet first. At this time, the elastic force of the torsion spring and the spring causes the rotating plate to rotate and fit against the limiting plate. The rotating plate is in a vertical state. At this time, the movable wheel rolls against the ground. When pulled out, the rolling of the movable wheel applies a force to the rotating plate to turn towards the limiting plate, so that the rotating plate fits against the limiting plate and remains in the limit position. This provides stable support for the part of the movable frame when it is pulled out. The slider and the slide groove cooperate to prevent the movable frame from being completely pulled out. At this time, it is convenient to maintain the overall electrical components.

[0026] 2. The electrical wiring on the mounting plate enters the wire groove through the through holes and is snapped in place by elastic clips, which facilitates the connection of wiring between electrical components. The main wire adopts an elastic spiral structure, which automatically extends and retracts when the moving frame is pushed in and pulled out. Attached Figure Description

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] Reference Figure 1 and Figure 2 This application provides a power distribution cabinet maintenance device that facilitates inspection and repair, comprising: a cabinet 1 with a door opening 7 on one side; an opening / closing door 2 hinged to the door opening 7; a movable frame 3 inside the cabinet 1; mounting plates 4 with multiple mounting plates 4 fixedly mounted on the movable frame 3; a moving mechanism 5 between the bottom of the movable frame 3 and the cabinet 1; and a wiring mechanism 6 between the movable frame 3, the mounting plates 4, and the cabinet 1. Electrical components are mounted on the mounting plates 4 with bolts, and the wiring of the electrical components is integrated through the wiring mechanism 6. The movable frame 3 can be pulled out or pushed into the cabinet 1 through the moving mechanism 5, thereby facilitating the inspection and repair of the electrical components after they are pulled out as a whole, improving the convenience of maintenance.

[0035] Reference Figures 1 to 4The moving mechanism 5 includes a fixed plate 51. Two pairs of fixed plates 51 are fixedly installed on both sides of the bottom of the moving frame 3. Fixed wheels 52 are rotatably installed between the bottom inner walls of the fixed plates 51. A fixed block 53 is fixedly installed at the bottom of the moving frame 3 near the opening / closing door 2. Fixed shafts 54 are fixedly installed on both sides of the fixed block 53. Rotating plates 55 are rotatably sleeved on the fixed shafts 54. Movable wheels 56 are installed between the inner walls of the rotating plates 55. A fixed limiter is fixedly installed at the bottom of the moving frame 3 on the side of the fixed block 53 near the fixed plate 51. Position plate 57 and limit plate 57 are movably attached to one side of rotating plate 55. A connecting plate 58 is fixedly installed on the other side of rotating plate 55. A spring 59 is installed between connecting plate 58 and the bottom of movable frame 3. The spring 59 is always in a compressed state. A torsion spring is installed between rotating plate 55 and fixed shaft 54. A support block 8 is fixedly installed at the bottom of the inner cavity of cabinet 1. The support block 8 is movably attached to the bottom of movable frame 3. A sliding groove 9 is opened on the support block 8. A slider 10 is fixedly installed at the bottom of movable frame 3. The slider 10 slides and engages with the sliding groove. 9. The cross-sections of slider 10 and groove 9 are T-shaped structures that fit together. The bottom of fixed wheel 52 is attached to the bottom plate of cabinet 1. When the movable frame 3 is pulled out, movable wheel 56 is pulled out of cabinet 1 first. At this time, the elastic force of torsion spring and spring 59 causes rotating plate 55 to rotate and attach to limiting plate 57. Then rotating plate 55 is in a vertical state. At this time, movable wheel 56 rolls on the ground. When pulled out, the rolling of movable wheel 56 applies a force to rotating plate 55 to turn to limiting plate 57, so that rotating plate 55 is attached to limiting plate 57 and keeps in the limiting position. The movable frame 3 is stably supported when it is pulled out. The slider 10 and the slide groove 9 cooperate to prevent the movable frame 3 from being completely pulled out. This facilitates the maintenance of the overall electrical components. When the movable frame 3 is pushed into the cabinet 1, the fixed wheel 52 supports the movable frame 3, and the movable wheel 56 is pushed when it moves to the bottom plate of the cabinet 1. This causes the rotating plate 55 to rotate against the elastic force of the spring 59 and the torsion spring. The rotating plate 55 rotates away from the limit plate 57, which facilitates the movable wheel 56 to enter the cabinet 1 and realizes the pushing of the movable frame 3.

[0036] Reference Figure 1 , Figure 2 and Figure 5 The wiring mechanism 6 includes a cable tray 61, a movable frame 3, and a mounting plate 4. The cable tray 61 is fixedly installed on the side away from the door opening 7. The mounting plate 4 has a through hole 63 that connects to the cable tray 61. A main cable 62 is fixedly installed between the cable tray 61 and the inner wall of the cabinet 1. Multiple elastic clips 64 are fixedly installed on the inner wall of the cable tray 61. The main cable 62 has an elastic spiral structure, and the elastic clips 64 have a C-shaped structure. The door opening 7 and the hinged door 2 have a matching "L"-shaped structure. The electrical components on the mounting plate 4 enter the cable tray 61 through the through hole 63 and are snapped together by the elastic clips 64, which facilitates the interconnection of electrical components. The main cable 62 adopts an elastic spiral structure, so it automatically extends and retracts when the movable frame 3 is pushed in and pulled out.

[0037] Working principle: When the movable frame 3 is pulled out, the movable wheel 56 is pulled out of the cabinet 1 first. At this time, the elastic force of the torsion spring and spring 59 causes the rotating plate 55 to rotate and fit against the limiting plate 57. The rotating plate 55 is then in a vertical state. At this time, the movable wheel 56 rolls against the ground. When pulled out, the rolling of the movable wheel 56 applies a force to the rotating plate 55 to turn towards the limiting plate 57, so that the rotating plate 55 fits against the limiting plate 57 and remains in a limited position. This provides stable support for the part of the movable frame 3 when it is pulled out. The slider 10 and the slide groove 9 cooperate to prevent the movable frame 3 from being completely pulled out. At this time, it is convenient to maintain the overall electrical components. When the movable frame 3 is pushed into the cabinet 1, the fixed wheel 52 supports the movable frame 3, and the movable wheel 56 is pushed when it moves to the bottom plate of the cabinet 1, so that the rotating plate 55 rotates against the elastic force of the spring 59 and the torsion spring. The rotating plate 55 rotates away from the limit plate 57, which facilitates the movable wheel 56 to enter the cabinet 1 and realizes the push-in of the movable frame 3. The electrical components on the mounting plate 4 enter the wire groove 61 through the through hole 63 and are snapped by the elastic clip 64, which facilitates the connection of the wiring between electrical components. The main wire 62 adopts an elastic spiral structure, which automatically extends and retracts during the pushing and pulling of the movable frame 3.
