[0050] A limiting block 8 is slidingly installed on the inner wall of the fixed plate 7, and a No. 1 spring is arranged between the limiting block 8 and the fixed plate 7. The No. 1 spring drives the limiting block 8 to reset and then limits the rotating knob 51.

[0051] The connecting knob 9 is sleeved on the inner wall of the control cabinet body 1;

[0052] The fan group 10 is slidingly installed on the inner wall of the control cabinet body 1, and is used for cooling the inside of the control cabinet body 1. When the operation in the electrical control cabinet is performed, the internal device is slid out, so that the contact risk of the maintenance personnel with the live part is reduced, and the safety of the operation is improved.

[0053] The rotating knob 51 is provided with a butt joint groove on the side close to the connecting knob 9, so that the connecting knob 9 can drive the rotating knob 51 to rotate. The left side of the limiting block 8 is provided with an inclined surface, so that the limiting block 8 limits the rotating knob 51 after being contacted.

[0054] The ventilation device comprises a heat exchange box 11, a sliding frame 12 and a cooling plate 13. The heat exchange box 11 is arranged on the inner wall of the control cabinet body 1 and is communicated with the hollow plate 6 through an expansion pipe. The sliding frame 12 is slidingly installed on the inner wall of the hollow plate 6. The cooling plate 13 is fixedly installed on the bottom of the sliding frame 12 and is communicated with the hollow plate 6 through a pipe. The air generated by the cooling plate 13 is guided and transmitted through the inside of the hollow plate 6, and finally enters the heat exchange box 11 through the expansion pipe to exchange heat. The air in the hollow plate 6 also enters the cooling plate 13 through the pipe to absorb heat from the bottom of the sliding frame 12.

[0055] When the embodiment works, the fan group 10 cools the inside of the control cabinet body 1. The air generated by the fan group 10 is guided and transmitted through the inside of the hollow plate 6, and finally enters the heat exchange box 11 through the expansion pipe to exchange heat.

[0056] Please refer to Figures 1-9 On the basis of the above embodiment, in another embodiment of the present application, the control cabinet body 1 is internally provided with a supporting device for supporting the bottom of the hollow plate 6 when it is extended, and a bundling device for arranging the wires in the control cabinet body 1, the supporting device comprises a sliding groove plate 20, a sliding plate 21 and a terminal rod 22, the sliding groove plate 20 is fixedly installed at the bottom of the fixed plate 7, the sliding plate 21 is fixedly installed on the inner wall of the control cabinet body 1, and the terminal rod 22 is fixedly installed on the inner wall of the control cabinet body 1. When the entire device is extended, the weight may be heavy, and the bottom needs to be supported at this time.

[0057] The supporting device further comprises a supporting leg 23, a sliding knob 24, a connecting rod 25 and a second spring 26, the supporting leg 23 is rotatably installed on the inner wall of the sliding groove plate 20, the sliding knob 24 is rotatably installed on the inner wall of the sliding groove plate 20, one side of the connecting rod 25 is rotatably installed on the left side of the supporting leg 23, the other side of the connecting rod 25 is rotatably installed on the left side of the sliding knob 24, and the second spring 26 is arranged between the connecting rod 25 and the sliding groove plate 20. The second spring 26 is reset to drive the sliding knob 24 to rotate, and stable bottom support can prevent the internal device from falling over and other accidents after being extended, thereby ensuring the safety of the operator.

[0058] The supporting device further comprises a control box 27, a sliding rod 28, a wire collecting plate 29 and a limiting knob 210, the control box 27 is arranged on the inner wall of the sliding frame 12, the sliding rod 28 is fixedly installed on the outer wall of the control cabinet body 1, the wire collecting plate 29 is slidably installed on the circumferential surface of the sliding rod 28, and the limiting knob 210 is rotatably installed on the outer wall of the control cabinet body 1. The bundled lines have clear marks and layout on the wire collecting plate 29, and when maintenance or repair is needed, the worker can quickly find the corresponding line, thereby improving the work efficiency.

[0059] The supporting device further comprises a fixed pulley 211 and a supporting rod 212, the fixed pulley 211 is arranged on the inner wall of the control cabinet body 1, and the supporting rod 212 is rotatably installed on the inner wall of the control cabinet body 1. A rope is arranged between the sliding groove plate 20 and the side of the supporting rod 212 close to the fixed pulley 211, the rope is in contact with the fixed pulley 211, and the other side of the supporting rod 212 is in contact with the line, thereby preventing the line from being pulled and torn when the length of the line is not reserved enough or does not have a suitable slackness.

[0060] The bundling device comprises a hollow frame 30, a triangular frame 31 and a hollow cylinder 32, the hollow frame 30 is fixedly installed on the outer wall of the control cabinet body 1, the triangular frame 31 is fixedly installed on the inner wall of the hollow frame 30, and the hollow cylinder 32 is fixedly installed on the inner wall of the hollow frame 30. After the layout of the lines is completed, the lines are bundled by the wire bundling belt, and at this time all the lines are concentrated and placed in the hollow cylinder 32 in a cylindrical shape.

[0061] The bundling device further comprises a clamping rod 33, a third spring 34 and a clamping button 35. The clamping rod 33 is slidingly installed in the inner wall of the tripod 31, the third spring 34 is arranged between the tripod 31 and the clamping rod 33, the clamping rod 33 is driven by the third spring 34 to clamp the wire, and the clamping button 35 is rotatably installed on the surface of the hollow cylinder 32. A first torsion spring is arranged between the clamping button 35 and the hollow cylinder 32, and the clamping button 35 is reset by the first torsion spring.

[0062] When the device is sliding out, the bottom needs to be supported due to the heavy weight. At this time, the fixed plate 7 is moved to drive the sliding groove plate 20 to move, and the second spring 26 is in a compressed state. The sliding groove plate 20 drives the supporting leg 23 and the sliding button 24 to move simultaneously. The sliding button 24 moves along the sliding plate 21. When the sliding groove plate 20 contacts the termination rod 22, the sliding button 24 is simultaneously separated from the sliding plate 21. At this time, the sliding button 24 is downwardly rotated by the reset of the second spring 26. The sliding button 24 drives the connecting rod 25 to rotate, and the connecting rod 25 drives the supporting leg 23 to rotate downwardly. The supporting leg 23 finally contacts the ground to support the bottom of the device when it is sliding out. The stable bottom support can prevent the internal device from falling and other accidents after sliding out, and ensures the safety of the operator. After the control box 27 is installed, the wire carried by the control box 27 is arranged by the collecting plate 29. When arranging, the collecting plate 29 is moved upwardly along the sliding rod 28 after the limiting of the collecting plate 29 is released by rotating the limiting button 210. At this time, each wire is placed one by one. The bundled wire has clear identification and arrangement on the collecting plate 29. When maintenance or repair is needed, the worker can quickly find the corresponding wire, and the working efficiency is improved.

[0063] In the layout of the lines of the control box 27, the lines of the control box 27 close to the collection board 29 are shorter than those in other positions, which may cause the lines to be pulled and torn when the control box 27 slides out and the length of the lines is not reserved or there is no appropriate slack. At this time, the sliding groove plate 20 is moved forward to pull the rope, so that the supporting rod 212 drives the other side to move upward through the lever principle, so that the reserved lines are pulled, the lines are lengthened and the slack is increased. After the layout of the lines is completed, the lines are bundled by the wire binding belt, and all the lines are concentrated and placed in the hollow cylinder 32 in a cylindrical shape, that is, the lines of the control box 27 are in contact with the clamping rod 33. The weight of the lines moves the clamping rod 33 and compresses the third spring 34. After the three positions are placed, the clamping rod 33 is driven by the third spring 34 to reset and clamp the lines. Clamping can keep the bundled lines in a specific position to prevent them from shaking or moving, ensuring the stability of the lines. The bundled lines will contact the detent button 35 at this time. When the lines are strongly pulled, the detent button 35 will rotate and clamp the lines, so that more force is required to pull the lines. When the lines are strongly pulled, the detent can play a certain protective role to prevent the lines from being stretched or damaged. This is particularly important for protecting the insulation layer, conductor and connector of the lines, and helps to prolong the service life of the lines.
