Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 6 As shown, a switch cabinet with auxiliary maintenance function according to an embodiment of the present invention includes a cabinet body 1; a cabinet door 10 is provided on the cabinet body 1; two sets of slide rails 11 are fixedly connected to the inner side wall of the cabinet body 1; two opposing slide rails 11 form a set; the two slide rails 11 are arranged opposite each other; two pulleys 13 are installed in the middle of the slide rails 11; a moving plate 12 is rotatably connected to the side wall of the two sets of pulleys 13; a first telescopic rod 14 is fixedly connected to the top of the slide rails 11; a limit rod 15 is rotatably connected to the end of the first telescopic rod 14; an elastic ball 17 is fixedly connected to the end of the limit rod 15; two fixing holes 16 are opened in the middle of the moving plate 12; a buffer assembly 2 is provided in the middle of the two slide rails 11; during operation, the equipment is installed on the corresponding slide rail 11 as required. When the equipment inside the switch cabinet is being maintained, the cabinet door 10 is opened, and the end of the first telescopic rod 14 drives the limit rod 15 to move upward, and the elastic ball 17 is pulled along with the limit rod 15. The movement generates elastic contraction, and the elastic ball 17 moves upward inside the fixed hole 16 along with the limit rod 15. When the elastic ball 17 moves out of the fixed hole 16, it pulls the moving plate 12 outward. The equipment moves outward with the moving plate 12. Then, the elastic ball 17 passes through the middle of another corresponding fixed hole 16 to fix the slide rail 11, thereby allowing the equipment to be inspected and repaired. Through the above structure, maintenance personnel can easily access the equipment inside the cabinet 1 that needs maintenance simply by pulling out the slide rail 11, effectively simplifying the maintenance steps. Due to the simplification of the maintenance steps, the maintenance time can also be shortened accordingly, enabling the equipment to be restored to normal operation quickly during maintenance work, reducing production downtime caused by equipment failure. The slide rail 11 can effectively move the equipment flexibly inside the cabinet 1, reducing the labor required for maintenance personnel to move heavy equipment out of the cabinet 1, thereby reducing the difficulty of maintenance.

[0026] like Figure 2 , Figure 5 , Figure 6 As shown, the buffer assembly 2 includes two sets of fixing blocks 21; one set of fixing blocks 21 is located at the bottom of one set of slide rails 11; the other set of fixing blocks 21 is located at the top of another set of slide rails 11; an adjusting plate 22 is rotatably connected to the middle of the fixing blocks 21; a second telescopic rod 23 is fixedly connected to the middle of the two adjusting plates 22; the second telescopic rod 23 is located on both sides of the cabinet 1; a damping spring 24 is fixedly connected to the middle of the two adjusting plates 22; the damping spring 24 is located outside the second telescopic rod 23; during operation, the mechanical vibration generated by the equipment is transmitted to the second telescopic rod 23 and the damping spring 24, and the second telescopic rod 23 and the damping spring 24 absorb the vibration generated by the equipment during operation. The vibration generated is that when one of the slide rails 11 is pulled out, the adjusting plate 22 rotates in the middle of the fixed block 21 as the slide rail 11 moves. At the same time, the second telescopic rod 23 and the damping spring 24 elastically extend and retract. Through the above structure, the cooperation between the second telescopic rod 23 and the damping spring 24 can effectively reduce the impact and vibration of the equipment during operation, reduce the damage to the equipment and other components inside the cabinet 1 caused by vibration. At the same time, when maintenance personnel pull out or push in the slide rail 11, the damping spring 24 can absorb some of the kinetic energy, making the operation more stable. By reducing impact and vibration, the damping spring 24 can extend the service life of the cabinet 1 and the equipment, and reduce the frequency of maintenance and replacement.

[0027] like Figure 1 , Figure 2 , Figure 6 As shown, two mounting slots 3 are provided on the inner side wall of the cabinet 1; the two mounting slots 3 are arranged opposite each other; two sets of heat dissipation holes 31 are provided on the side wall of the cabinet 1; the two sets of heat dissipation holes 31 are located at the corresponding mounting slots 3; a cooling fan 32 is installed in the middle of the mounting slot 3; two protective nets 33 are fixed to the inner side wall of the cabinet 1; the two protective nets 33 are fixed to the corresponding mounting slots 3. During operation, the heat inside the equipment will be dissipated into the cabinet 1. After the cooling fan 32 is powered on, it will rotate at high speed and discharge the airflow inside the cabinet 1 through multiple heat dissipation holes 31 into the external airflow, thereby ventilating the inside of the cabinet 1 and quickly transferring heat to the outside of the cabinet 1. The above structure can increase the air convection inside the cabinet 1, effectively accelerate the dissipation of heat inside the cabinet 1, and enable effective heat exchange between the inside of the cabinet 1 and the outside air through the cooling fan 32, thereby reducing the temperature inside the cabinet 1. This can effectively reduce the temperature of the equipment during operation, reduce the occurrence of failures due to overheating, and effectively extend the service life of the equipment.

[0028] like Figure 2 , Figure 4 , Figure 6As shown, multiple sets of cable management plates 4 are installed on the side wall of the cabinet 1; the cable management plates 4 are arc-shaped; the cable management plates 4 are elastic; a fixing component 5 is provided between the multiple sets of cable management plates 4 and the inner side wall of the cabinet 1; a rubber pad 41 is fixedly connected to the middle of the cable management plate 4; during operation, multiple cable management plates 4 are installed on the inner side wall of the cabinet 1 through the fixing component 5. When the equipment is installed on the slide rail 11, the cables inside the cabinet 1 are classified. First, two opposing cable management plates 4 are pulled outward. The elastic bending of the cable management plates 4 places the cables in the middle of the cable management plates 4. The rubber pad 41 directly contacts the cables and fits them tightly, thereby fixing and organizing the cables. The above structure can effectively fix and isolate the cables inside the cabinet 1, reduce the cables from being messily tangled together inside the cabinet 1, enable maintenance personnel to quickly find the required wires, reduce maintenance time and difficulty, and fix the cables to effectively reduce the movement or falling of cables inside the cabinet 1, thereby increasing the stability and safety of the circuit.

[0029] like Figure 2 , Figure 4 , Figure 6 As shown, the fixing component 5 includes two mounting plates 51; the mounting plates 51 are installed on the inner side wall of the cabinet 1; two mounting bolts 52 are installed in the middle of the mounting plates 51; multiple mounting blocks 53 are fixedly connected to the middle of the mounting plates 51; screws 54 are threadedly connected to the middle of the mounting blocks 53; every two rubber pads 41 are fixed to the end of the screws 54; during operation, when the cable tray 4 is installed inside the cabinet 1, the mounting plates 51 are first fixed to the designated position on the inner side wall of the cabinet 1 by the multiple mounting bolts 52, the screws 54 are aligned with the positions of the mounting blocks 53, the screws 54 are rotated to enter the middle of the mounting blocks 53 and fixed. Through the above structure, the rubber pads 41 can be quickly installed and removed, allowing maintenance personnel to complete the operation more quickly when managing wires, reducing complex steps and tool usage, and enabling maintenance personnel to quickly remove the cable bundle when needed, reducing interference and impact on other equipment during maintenance.

[0030] like Figure 3 and Figure 6 As shown, a first magnetic block 6 is fixed to the side wall of the slide rail 11; two second magnetic blocks 61 are fixed to the inner side wall of the cabinet 1; the two second magnetic blocks 61 are fixed at the corresponding positions of the two first magnetic blocks 6; the first magnetic blocks 6 and the second magnetic blocks 61 attract each other when they are close; during operation, when the equipment is installed on the slide rail 11 and pushed into the cabinet 1, the first magnetic block 6 moves towards the position of the second magnetic block 61. As the first magnetic block 6 continues to move and approach the second magnetic block 61, the magnetic force causes the first magnetic block 6 and the second magnetic block 61 to attract each other. Through the above structure, the magnetic force between the first magnetic block 6 and the second magnetic block 61 can keep the slide rail 11 and the equipment stable in the cabinet 1, reduce the shaking caused by vibration or external force, enhance the connection strength between the slide rail 11 and the cabinet 1, and effectively increase the stability between the slide rail 11 and the cabinet 1.

[0031] like Figure 1 and Figure 6 As shown, a filter screen 7 is provided in the middle of the heat dissipation hole 31; the filter screen 7 is fixed in the middle of the heat dissipation hole 31; during operation, when the cabinet 1 is in use, the filter screen 7 blocks dust and impurities from the external environment from entering the cabinet 1 through the heat dissipation hole 31. The above structure filters dust and particulate impurities in the air, effectively reducing these impurities inside the cabinet 1, reducing the accumulation and damage of dust and impurities on electrical equipment and lines, and reducing the problem of decreased heat dissipation performance of the equipment.

[0032] During operation, the equipment is installed on the corresponding slide rail 11 as required. When the equipment inside the switch cabinet is under maintenance, the cabinet door 10 is opened. First, the end of the first telescopic rod 14 moves the limiting rod 15 upward. The elastic ball 17 elastically contracts as the limiting rod 15 is pulled. The elastic ball 17 moves upward inside the fixing hole 16 along with the limiting rod 15. After the elastic ball 17 moves out of the fixing hole 16, the moving plate 12 is pulled outward. The equipment moves outward with the moving plate 12. Then, the elastic ball 17 is passed through the middle of another corresponding fixing hole 16 to fix the slide rail 11, thereby... During equipment inspection and maintenance, the mechanical vibrations generated by the equipment during operation are transmitted to the second telescopic rod 23 and the damping spring 24. These vibrations are absorbed by the second telescopic rod 23 and the damping spring 24. When one of the slide rails 11 is pulled out, the adjusting plate 22 rotates in the middle of the fixed block 21 as the slide rail 11 moves. Simultaneously, the second telescopic rod 23 and the damping spring 24 elastically extend and retract. During equipment use, heat inside the equipment dissipates into the cabinet 1. When the cooling fan 32 is powered on, it rotates at high speed, dissipating heat from inside the cabinet 1. The airflow passes through multiple heat dissipation holes 31 and is discharged into the external airflow, thereby ventilating the inside of the cabinet 1 and allowing heat to be quickly transferred to the outside of the cabinet 1. Multiple cable trays 4 are installed on the inner side wall of the cabinet 1 by fixing components 5. When the equipment is installed on the slide rail 11, the cables inside the cabinet 1 are classified. First, two opposing cable trays 4 are pulled outward. The elastic bending of the cable trays 4 places the cables in the middle of the cable trays 4. The rubber pads 41 make direct contact with the cables and fit tightly against them, thereby fixing and organizing the cables. When the cable trays 4 are installed inside the cabinet 1, first... First, the mounting plate 51 is fixed to the designated position on the inner side wall of the cabinet 1 using multiple mounting bolts 52. The screw 54 is aligned with the position of the mounting block 53, and the screw 54 is rotated to enter the middle of the mounting block 53 and fixed. When the equipment is pushed into the cabinet 1 on the slide rail 11, the first magnetic block 6 moves towards the position of the second magnetic block 61. As the first magnetic block 6 continues to move and gets closer to the second magnetic block 61, the first magnetic block 6 and the second magnetic block 61 are attracted by magnetic force. During the use of the cabinet 1, the filter screen 7 blocks dust and impurities from the external environment from entering the cabinet 1 through the heat dissipation hole 31.
