Several circuit breakers and electronic instruments are installed on the mounting tracks, and the above-mentioned equipment are electrically connected to the busbars through branch copper bars to monitor and protect the safety of each branch circuit. Nowadays, when a short circuit or overload occurs in a branch circuit, the circuit breaker on the branch circuit will automatically trip, thereby cutting off the power supply and ensuring the safety of electricity use.

[0003] At present, the existing low-voltage switch cabinet with anti-leakage function has the following shortcomings in use: First, when using the low-voltage switch cabinet, the wiring in the cabinet often bears the important task of current transmission. Now most of the wiring plugs are directly inserted and stuck in the socket. After long-term use, it is easy for the wiring plug to be loose or improperly tight. If the wiring is not firm, it will lead to problems such as poor current transmission and circuit failure. The leakage problem is also very common. Once leakage occurs, it will cause great harm to personnel and equipment, because there is static electricity in the equipment, which causes a large amount of dust or debris to accumulate, which will cause equipment aging, excessive temperature, aging of insulation materials and other problems. ‌ The existing low-voltage switch cabinet with anti-leakage function has the above problems.

The corresponding sides of the two reinforced insulating strips 12 are provided with limited long grooves 39. The inner sides of the two limited long grooves 39 are slidably provided with connecting end plates 38. Two threaded screws 8 are vertically installed on the inner side of the low-voltage switch cabinet body 1. The outer surfaces of the two threaded screws 8 are slidably sleeved with threaded sleeves 6. The connecting end plates 38 are fixedly connected to the threaded sleeves 6. The outer surfaces of the two threaded sleeves 6 are fixedly connected with guide blocks 11. The two guide blocks 11 are respectively fixedly connected to the built-in inclined plane frames 10. A self-assembled driver 40 is installed on the upper inner side of the low-voltage switch cabinet body 1.

[0026] According to the above technical solution, the switches of multiple automatic control components are turned on at a fixed time from an external controller. First, the assembled driver 40 is turned on. After operation, it can drive the two threaded screws 8 to rotate simultaneously. The motor on one side of the assembled driver 40 drives the threaded screw 8 connected on one side to rotate, and then drives the other threaded screw 8 to rotate synchronously through the pulley, so that the two threaded sleeves 6 are driven to slide upward along the threaded screw 8 at the same time. When the threaded sleeve 6 slides, it will drive the connecting end plate 38 to slide steadily downward in the limiting long groove 39, further drive the guide block 11 to move, and drive the built-in inclined plane frame 1 under the movement of the guide block 11 0 movement, thereby driving the safety protection operation box 5 to move upward as a whole. The insulated opening and closing door 2 is used to isolate the outside and play a protective role. The method of using the low-voltage switchgear mainly includes the following steps: Confirm the power switch status: Check the position of the power switch, which is usually located at the top or bottom of the distribution cabinet, and confirm that the power switch is in the "off" or "0" position. Use a voltmeter or ammeter to confirm. If the reading is zero, it means that the power switch is in the off state. Check the power indicator light. If the indicator light is off, it means that the power switch is off. Open the distribution cabinet door and check the internal equipment: After confirming the power After the power switch is turned off, open the door of the power distribution cabinet and check whether the power switch, circuit breaker, contactor and other equipment are normal, including their location, identification, connection lines, etc. Connect the equipment that needs power: confirm the voltage and current of the equipment in order to select the appropriate circuit breaker or contactor. According to the voltage and current of the equipment, find the corresponding circuit breaker or contactor, and connect the power cord of the equipment. Confirm whether the connection is firm to avoid loosening or falling off. Operate the power switch: supply the operating circuit power. After the status indication is normal, operate according to the type of incoming switch: If it is an isolating switch and a fixed circuit breaker, Close the isolating switch first, then the circuit breaker. If it is a drawer-type frame circuit breaker, first swing the circuit breaker to the working position, then close the circuit breaker, observe and confirm: observe the changes in voltage and current after closing, ensure the three-phase voltage and current balance, and after confirming that the circuit breaker is normal, hang up the "power supplied" warning sign, power outage operation (if power outage is required): confirm that all load switches are disconnected, according to the type of incoming switch, first disconnect the circuit breaker, then operate the isolating switch or swing out the drawer-type frame circuit breaker, cut off the operating power of the circuit breaker, and after confirming that the circuit breaker output has no power, hang up the "power outage" warning sign.

[0027] A further technical solution is that oblique guide openings 19 are opened on both sides of the safety protection operation box 5, and a transverse connecting rod 41 is slidably arranged on the inner side of the oblique guide opening 19. The transverse connecting rod 41 is fixedly connected to the linkage bottom plate 20, and both ends of the transverse connecting rod 41 pass through the oblique guide opening 19 and are rotatably connected to the inclined guide bar 13.

[0028] According to the above technical solution, after reaching the predetermined position, the micro automatic telescopic rod 4 automatically opens the extended end to pull the top arc lifting piece 16 to move, and then the linkage lifting plate 9 is driven by the top arc lifting piece 16 to move downward. When the linkage lifting plate 9 is lowered, it can move in the safety protection operation box 5 and drive the linkage bottom plate 20 to move. When the linkage bottom plate 20 moves, it can drive the transverse connecting rod 41 to move, thereby driving the transverse connecting rod 41 to slide on the inner side of the oblique guide opening 19, so that the inclined guide bar 13 connected thereto can be driven to slide smoothly upward on the inner surface of the built-in inclined frame 10. In the process of sliding of the two inclined guide bars 13, the long tool pressure plate 36 is driven to move, and further a plurality of pressure plate groove teeth 37 are driven to move. After the long tool pressure plate 36 and the pressure plate groove teeth 37 move to the predetermined position, they are engaged with the front edge of the wiring plug 33. The loose and unstable wiring plug 33 is resisted, thereby reinserting the loose wiring plug 33 to ensure the stability of the connection, which is beneficial to the use of the low-voltage switch cabinet. The wiring plug 33 can be automatically maintained and reinforced to prevent the wiring from loosening and improve the stability of current transmission. The assembled driver 40 is turned on, and after operation, it can drive the two threaded screws 8 to rotate at the same time. The motor on one side of the assembled driver 40 drives the threaded screw 8 connected on one side to rotate, and then drives the other threaded screw 8 to rotate synchronously through the pulley, so that the two threaded sleeves 6 are driven to slide upward along the threaded screw 8 at the same time. When the threaded sleeve 6 slides, it will drive the connecting end plate 38 to slide smoothly down in the limiting long groove 39, further drive the guide block 11 to move, and the built-in inclined frame 10 is driven to move under the movement of the guide block 11, thereby driving the safety protection operation box 5 to move upward as a whole.

[0029] A further technical solution is that a collecting bottom box 21 is provided at the bottom end of the safety protection operation box 5, a protective mesh plate 34 is provided on one side of the collecting bottom box 21, an exhaust fan 3 is provided at the upper end of the low-voltage switch cabinet body 1, and a conveying hose 42 is fixedly connected to the bottom end of the exhaust fan 3, and the exhaust fan 3 is connected to the collecting bottom box 21 through the conveying hose 42.

[0030] According to the above technical solution, the plurality of brake control pull plates 26 are pushed to move in the through opening 18 under the drive of the linkage bottom plate 20, and the movement of the brake control pull plates 26 drives the limit ring buckle 25 to move, so that the limit ring buckle 25 is subjected to an outward force, so that the limit ring buckle 25 drives the telescopic support plate 30 to move, thereby driving the outer surface of the limit slider 28 to slide outward and slide smoothly along the limiting through groove 31. During the process, the horizontal movement of the limit ring buckle 25 directly drives the multifunctional ring piece 24 to move, so that the multifunctional ring piece 24 is close to the wiring plug 3 3, further let the anti-static non-stick cleaning brush 27 clean the dust and debris adsorbed on the terminal of the wiring plug 33, and the cleaned dust and debris fall off. Under the operation of the exhaust fan 3, the dust is sucked into the collection bottom box 21 through the protective mesh plate 34, and is transported to the exhaust fan 3 through the conveying hose 42 for discharge. The micro automatic telescopic rod 4 automatically opens the extended end to pull the top arc lifting piece 16 to move, and then the linkage lifting plate 9 is driven by the top arc lifting piece 16 to move downward, and the linkage lifting plate 9 can move in the safety protection operation box 5 when it is lowered. The linkage bottom plate 20 moves and drives the linkage bottom plate 20 to move. When the linkage bottom plate 20 moves, it can drive the transverse connecting rod 41 to move, thereby driving the transverse connecting rod 41 to slide on the inner side of the oblique guide opening 19, so that the inclined guide bar 13 connected thereto is driven to slide smoothly upward on the inner surface of the built-in inclined frame 10. During the sliding process of the two inclined guide bars 13, the long tool pressure plate 36 is driven to move, and further drives a plurality of pressure plate groove teeth 37 to move. After the long tool pressure plate 36 and the pressure plate groove teeth 37 move to a predetermined position, they are locked with the front edge of the wiring plug 33. After using this equipment, it is necessary to regularly inspect and maintain the low-voltage switch cabinet, replace aging equipment and components in time, strictly implement operating procedures, and prevent misoperation. In the industrial production process, the low-voltage switch cabinet, as a control device, can control and protect various motors, pumps, valves and other equipment. It can start and stop the power equipment according to the process requirements, and ensure that the power supply is cut off in time under abnormal conditions to protect the safety of equipment and personnel. In addition, low-voltage switchgear is also widely used in large-scale industrial equipment such as machine tools, printing machinery, and metallurgical machinery to ensure the normal operation and safety of factories and workshops. The appropriate temperature range is crucial to the life of the equipment. The high temperature environment will accelerate the aging of internal components, while the appropriate temperature can prolong the service life. For example, in a high-temperature industrial plant, the life of the equipment may be shortened to 15-20 years, while in indoor places with suitable temperature, the life can be close to normal water, and then driven by the linkage bottom plate 20, multiple brake control pull plates 26 are pushed to move in the through port 18, and the movement of the brake control pull plate 26 drives the limit ring buckle 25 to move, so that the limit ring buckle 25 is subjected to an outward force, so that the limit ring buckle 25 drives the telescopic support plate 30 to move, thereby driving the outer surface of the limit slider 28 to slide outward and slide smoothly along the limiting through groove 31,During the process, the horizontal movement of the limit ring buckle 25 directly drives the multifunctional ring piece 24 to move, so that the multifunctional ring piece 24 is close to the wiring plug 33, and the anti-static non-stick cleaning brush 27 further cleans the dust and debris adsorbed on the wiring terminal of the wiring plug 33. The dust and debris fall off after cleaning, which is conducive to cleaning the internal wiring terminal, preventing the accumulation of dust and debris adsorbed by static electricity, causing line aging and poor contact, and further improving the maintenance efficiency and safety quality of the overall low-voltage switch cabinet.

[0031] Specific use of the present invention: In an inspection table device for physical examination of the present invention, the switches of multiple automatic control components are turned on at a fixed time from an external controller. First, the integrated driver 40 is turned on. After operation, it can drive the two threaded screws 8 to rotate simultaneously. The threaded screw 8 connected to one side is driven by a motor on one side inside the integrated driver 40 to rotate, and then the other threaded screw 8 is driven to rotate synchronously through a pulley, so that the two threaded sleeves 6 are driven to slide upward along the threaded screw 8 at the same time. When the threaded sleeve 6 slides, it will drive the connecting end plate 38 to slide steadily downward in the limiting long groove 39, further driving the guide block 11 to move, and the movement of the guide block 11 drives the built-in inclined frame 10 to move, thereby driving the safety protection operation box 5 to move upward as a whole. When it reaches the predetermined position, The micro automatic telescopic rod 4 automatically opens the extended end to pull the top arc lifting piece 16 to move, and then the linkage lifting plate 9 is driven by the top arc lifting piece 16 to move downward. When the linkage lifting plate 9 is lowered, it can move in the safety protection operation box 5 and drive the linkage bottom plate 20 to move. When the linkage bottom plate 20 moves, it can drive the transverse connecting rod 41 to move, thereby driving the transverse connecting rod 41 to slide on the inner side of the oblique guide opening 19, so that the inclined guide bar 13 connected thereto can be driven to slide smoothly upward on the inner surface of the built-in inclined frame 10. In the process of sliding of the two inclined guide bars 13, the long tool pressure plate 36 is driven to move, and further a plurality of pressure plate groove teeth 37 are driven to move. After the long tool pressure plate 36 and the pressure plate groove teeth 37 move to the predetermined position, they are connected to the wiring plug 33. The front edge of the card is in contact with the plug 33, so that the loose and unstable wiring plug 33 is reinserted to ensure the stability of the connection. After using this equipment, it is still necessary to regularly inspect and maintain the low-voltage switch cabinet, replace aging equipment and components in time, strictly implement operating procedures, and prevent misoperation. In the industrial production process, the low-voltage switch cabinet, as a control device, can control and protect various motors, pumps, valves and other equipment. It can start and stop the power equipment according to the process requirements, and ensure that the power supply is cut off in time under abnormal circumstances to protect the safety of equipment and personnel. Then, driven by the linkage bottom plate 20, multiple brake control pull plates 26 are pushed to move in the through port 18, and the movement of the brake control pull plate 26 drives the limit ring buckle 25 to move, so that the limit ring The buckle 25 is subjected to an outward force, so that the limit ring buckle 25 drives the telescopic support plate 30 to move, thereby driving the outer surface of the limit slider 28 to slide outward and slide smoothly along the limiting groove 31. During the process, the horizontal movement of the limit ring buckle 25 directly drives the multifunctional ring piece 24 to move, so that the multifunctional ring piece 24 is close to the wiring plug 33, and further allows the anti-static non-stick cleaning brush 27 to clean the dust and debris adsorbed on the wiring terminal of the wiring plug 33. The cleaned dust and debris fall off, and under the operation of the exhaust fan 3, the dust is sucked into the collection bottom box 21 through the protective mesh plate 34, and then transported to the exhaust fan 3 through the conveying hose 42 for discharge. After the work is completed, the assembled driver 40 is opened, and after operation, it can drive the two threaded screws 8 to rotate at the same time.The motor on one side drives the threaded screw 8 connected on one side to rotate inside the self-assembled driver 40, and then drives the other threaded screw 8 to rotate synchronously through the pulley, so that the two threaded sleeves 6 are driven to slide upward along the threaded screw 8 at the same time. When the threaded sleeve 6 slides, it will drive the connecting end plate 38 to slide steadily downward in the limit long groove 39, further driving the guide block 11 to move, and the movement of the guide block 11 drives the built-in inclined plane frame 10 to move, thereby driving the safety protection operation box 5 to move upward as a whole.
