[0030] like Figures 1 to 4 As shown, the following preferred technical solutions are provided:

[0031] A self-inspection and self-repair intelligent power distribution cabinet comprises a cabinet body 1 and various control switches and a master switch 2, wherein the outer side of the external terminal 2a of the master switch 2 is sleeved with a fourth spring 2b, and the cabinet also comprises: a wiring assembly 3 for connecting an external line and the master switch 2, a detection assembly 4 for detecting whether the master switch 2 and the external line are normally connected, and a replacement assembly 5 for automatically replacing the wiring assembly 3, wherein the detection assembly 4 and the replacement assembly 5 are both installed in the cabinet body 1 through an inspection frame 6 and face the master switch 2, the detection assembly 4 and the replacement assembly 5 are connected through a walking mechanism 4c, the wiring assembly 3 is arranged on the inspection frame 6 through a card assembly 6a, and the card assembly 6a and the inspection frame 6 are connected through a transmission mechanism 6b.

[0032] The present invention replaces the connection structure between the traditional switch and the external wiring with the wiring assembly 3, realizes the connection between the main control switch 2 and the external line, improves the service life of the external line, optimizes the connection method between the two, and reduces the failure rate. At the same time, the wiring assembly 3 can be quickly inspected and replaced after it is damaged. The working status between the wiring assembly 3 and the main control switch 2 is detected by the detection assembly 4. If the detection finds that the connection between the wiring assembly 3 and the main control switch 2 is damaged, the new wiring assembly 3 is replaced by the replacement assembly 5, thereby improving safety and maintenance efficiency in this self-inspection and self-repair process.

[0033] like Figures 5 to 7 As shown, the following preferred technical solutions are provided:

[0034] The wiring assembly 3 includes a wiring seat 3a and two clamping heads 3b, the two clamping heads 3b are symmetrically installed at the two ends of the wiring seat 3a in the length direction and are slidably connected to the wiring seat 3a, the two clamping heads 3b are connected by a first spring 3c, the two ends of the first spring 3c respectively abut the two clamping heads 3b, the first spring 3c is arranged at the bottom of the wiring seat 3a, and the top of the wiring seat 3a is symmetrically plugged with adjusting rods 3d, the ends of the two adjusting rods 3d are both wedge-shaped structures, and a pressing bolt 3e is abutted between the two adjusting rods 3d, and the lower end of the pressing bolt 3e is threadedly connected to the wiring seat 3a. The upper end of the bolt 3e is a conical structure that can cooperate with the wedge-shaped structures of the two adjusting rods 3d. The two ends of the terminal block 3a in the length direction are fixedly installed with fixed seats 3a1. The fixed seats 3a1 and the corresponding adjusting rods 3d are connected by abutting rods 3a2, and the other ends of the two fixed seats 3a1 can abut against the two sides of the connecting port 2c of the master switch 2. The two ends of the abutting rod 3a2 abut against the corresponding adjusting rod 3d and the clamp head 3b respectively, and the two end structures of the abutting rod 3a2 are also wedge-shaped structures, and the wedge-shaped structure at the upper end of the abutting rod 3a2 fits with the wedge-shaped structure of the corresponding adjusting rod 3d.

[0035] A return pin 3d1 and a second spring 3d2 are provided in the middle of the adjusting rod 3d and the abutting rod 3a2, and a movable groove is opened in the middle of the adjusting rod 3d and the abutting rod 3a2. The return pin 3d1 on the adjusting rod 3d is perpendicular to the axial direction of the adjusting rod 3d and is inserted in the corresponding movable groove, and the return pin 3d1 on the abutting rod 3a2 is perpendicular to the axial direction of the abutting rod 3a2 and is inserted in the corresponding movable groove, one of the two ends of the second spring 3d2 abuts between the corresponding return pin 3d1 and the corresponding adjusting rod 3d, and the other two ends of the second spring 3d2 abuts between the corresponding return pin 3d1 and the corresponding abutting rod 3a2, the return pin 3d1 connected to the adjusting rod 3d is inserted in the wiring seat 3a, and the return pin 3d1 connected to the abutting rod 3a2 is inserted in the corresponding fixed seat 3a1;

[0036] A docking joint 3b1 is installed in the clamp head 3b. The docking joint 3b1 is inserted into the clamp head 3b and connected to the clamp head 3b through a third spring 3b2. The third spring 3b2 is installed in the clamp head 3b. Both ends of the third spring 3b2 abut against the clamp head 3b and the docking joint 3b1 respectively. A fusible coil 3f abuts between the two docking joints 3b1.

[0037] A slot piece 3e1 is provided on the top of the wire pressing bolt 3e, and the spare wiring assembly 3 is connected to the card assembly 6a through the slot piece 3e1. The slot piece 3e1 is square outside and round inside, and the slot piece 3e1 and the wire pressing bolt 3e are connected by connecting ribs.

[0038] Specifically, in order to solve the technical problem of connecting the terminal 2a of the master switch 2 with the external circuit and the terminal assembly 3, the present invention forms a fastening structure through the cooperation between the clamp head 3b and the terminal seat 3a and each adjusting rod 3d and the abutting rod 3a2. By rotating the wire pressing bolt 3e, the clamp heads 3b are driven to be close to each other. First, due to the cooperation between the conical structure at the upper end of the wire pressing bolt 3e and the wedge-shaped structure of the adjusting rod 3d, when the wire pressing bolt 3e is rotated downward, the wire pressing bolt 3e pushes the adjusting rod 3d to move toward each other, and the lower connecting rod also Due to the cooperation with the wedge-shaped structure at the end of the adjusting rod 3d, the abutting rod 3a2 moves downward, and the other end of the abutting rod 3a2 pushes the clamping head 3b close to each other, so that the third spring 3b2 always presses the docking joint 3b1 and the fusible coil 3f tightly; under the compression of the wire-pressing bolt 3e, the fusible coil 3f is tightly attached to the external terminal 2a of the master switch 2 and the connector of the external circuit, and in this process, the two fixing seats 3a1 respectively press the two sides of the connecting port 2c of the master switch 2 tightly, so that the entire wiring assembly 3 is clamped on the master switch 2.

[0039] On the contrary, when the tightening state is released, the wire pressing bolt 3e is rotated in the opposite direction, and the clamping head 3b is reset away from each other under the action of the first spring 3c. At the same time, the adjusting rod 3d and the abutting rod 3a2 are reset under the action of the return pin 3d1 and the second spring 3d2. The fuse coil 3f is disconnected from the terminal 2a of the main control switch 2 and the wire end of the external line. If the fuse coil 3f of the wiring assembly 3 is damaged by the fuse, during the resetting process, the fourth spring 2b on the outside of the terminal 2a of the main control switch 2 will pop the damaged wiring assembly 3 out of the connection port 2c of the main control switch 2.

[0040] like Figures 1 to 4 As shown, the following preferred technical solutions are provided:

[0041] The detection component 4 includes a multi-degree-of-freedom detection gripper 4a connected to the circuit detection module. The detection gripper 4a is connected to the walking mechanism 4c through the first electric push rod 4b. The walking mechanism 4c includes a motor 4c1 and a transmission module 4c2. The motor 4c1 and the transmission module 4c2 are both installed in the cabinet 1. The motor 4c1 is connected to the transmission module 4c2. The transmission module 4c2 is connected to the first electric push rod 4b through the screw module 4c3 and the screw seat 4c4. The screw module 4c3 and the screw seat 4c4 are transmission-connected. The first electric push rod 4b is installed on the screw seat 4c4. The screw seat 4c4 is connected to the replacement component 5.

[0042] Specifically, in order to solve the technical problem of detecting the working condition between the main control switch 2 and the connection point of the external circuit, the present invention drives the transmission module 4c2 and the screw module 4c3 to move by the motor 4c1, realizes the movement of the screw seat 4c4, and then drives the movement of the first electric push rod 4b and the detection clamp 4a. When detecting the working condition of the main control switch 2 and the wiring assembly 3, it is necessary to move the detection clamp 4a to the connection point between the two for detection by the circuit detection module.

[0043] like Figure 3 and Figure 4 As shown, the following preferred technical solutions are provided:

[0044] The replacement component 5 includes an electric bolt driver set and a sliding frame 5b. The electric screwdriver set 5a is installed on the sliding frame 5b through a movable seat 5c. The sliding frame 5b is slidably installed on the maintenance frame 6. The movable seat 5c is slidably connected to the screw seat 4c4 through a guide rod 5d.

[0045] Specifically, in order to solve the technical problem of replacing the damaged wiring assembly 3, the present invention realizes the synchronous horizontal movement of the replacement assembly 5 and the detection assembly 4 through the guide rod 5d. When the detection is performed, the electric screwdriver assembly 5a does not contact the spare wiring assembly 3, and moves with the detection assembly 4. When the detection finds that the wiring assembly 3 in use is damaged, the card assembly 6a and the transmission mechanism 6b further move the electric screwdriver assembly 5a along the direction of the guide rod 5d to the top of the wire pressing bolt 3e of the wiring assembly 3 in use, and drive the wire pressing bolt 3e to rotate to loosen the wiring assembly 3 in use;

[0046] When replacing parts, the transmission mechanism 6b drives the card assembly 6a to move to a certain position toward the main control switch 2, and the replacement component 5 and the detection component 4 move horizontally synchronously. During this process, the electric screwdriver group 5a first docks with the wire-pressing bolt 3e of the spare wiring component 3, and drives the wiring component 3 to slide on the card assembly 6a to a position facing the main control switch 2, and then the transmission mechanism 6b drives the card assembly 6a to further clamp the spare wiring component 3 into the connection port 2c of the main control switch 2, and the electric screwdriver group 5a works to tighten the wire-pressing bolt 3e.

[0047] like Figures 1 to 7 As shown, the following preferred technical solutions are provided:

The card pairing frames 6a1 are provided with a card slot 6a2 for clamping the spare wiring assembly 3 and an upper opening 6a3 for clamping the wiring assembly 3 into the card slot 6a2, as well as a separation opening 6a4 for separating the wiring assembly 3 from the card pairing frame 6a, and the separation opening 6a4 is directly opposite to the main control switch 2, and the card slot 6a2 is slidably connected to the card slot piece 3e1 of the wire pressing bolt 3e.

[0049] Specifically, in order to solve the technical problem of placing and moving the spare wiring assembly 3, the present invention inserts the slot piece 3e1 at the top of the wire pressing bolt 3e on the spare wiring assembly 3 from the upper opening 6a3 of the card frame 6a1 into the slot 6a2. When replacing, the spare wiring assembly 3 slides along the slot 6a2 to the separation opening 6a4, and the electric bolt cutter group drives the wire pressing bolt 3e to rotate. Since the slot piece 3e1 is a rectangular structure and cannot rotate with the wire pressing bolt 3e, the connecting rib between the wire pressing bolt 3e and the slot piece 3e1 is disconnected, so that the wiring assembly 3 is separated from the slot piece 3e1. Under the action of the electric screwdriver group 5a, the wiring assembly 3 is separated from the card frame 6a1 at the separation opening 6a4.

[0050] The transmission mechanism 6b includes two groups of transmission gears 6b1 that are meshed with each other and are respectively installed on both sides of the maintenance frame 6. The transmission gears 6b1 are connected to the corresponding card frames 6a1 through a connecting plate 6b4. The connecting plate 6b4 on one of the transmission gears 6b1 is connected to the maintenance frame 6 through a second electric push rod 6b3, and the lower end of the transmission gear 6b1 is transmission-connected with a transmission rack 6b2. The other end of the transmission rack 6b2 is connected to the lower end of the sliding frame 5b. The second electric push rod 6b3 is installed on the maintenance frame 6 through a mounting seat 6b5. The sliding frame 5b and the maintenance frame 6 are slidingly connected through a guide groove 6c.

[0051] Specifically, in order to solve the technical problem of inserting the spare wiring assembly 3 into the main control switch 2, the present invention drives the connecting plate 6b4 and the two transmission gears 6b1 to move through the second electric push rod 6b3, and the two transmission gears 6b1 are engaged to drive the transmission rack 6b2 at the lower end to move, so as to realize the sliding of the sliding frame 5b on the maintenance frame 6, and then the sliding frame 5b drives the replacement component 5 to move synchronously toward the main control switch 2, wherein the process of moving toward the main control switch 2 is divided into two parts, wherein the first part is when the card rack 6a1 is rotated to a certain position, at which time the electric screwdriver group 5a can contact the wire pressing bolt 3e of the spare wiring assembly 3, and then the electric screwdriver group 5a moves the spare wiring assembly 3 along the card slot 6a2 to the separation port 6a4 driven by the walking mechanism 4c; the second part is when the spare wiring assembly 3 moves to the separation port 6a4, the transmission mechanism 6b continues to drive the card rack 6a1 to move and inserts the spare wiring assembly 3 into the connection port 2c of the main control switch 2.
