[0030] It should be noted that the connection and control of the five-protection interlocking mechanism ensures the coordinated operation of the various components of the switch cabinet, thereby improving the stability and reliability of the switch cabinet. The operating hole protective cover 240 is made of metal material, which has the characteristics of corrosion resistance and good insulation performance. It can effectively protect the operating hole, extend the service life of the five-protection interlocking mechanism, and effectively prevent the protective cover 240 from being damaged by staff due to misoperation. In addition, the five-protection interlocking mechanism of this embodiment has a compact structure, is easy to install, and is relatively simple to repair and replace parts, which can effectively improve the maintenance efficiency and service life of the switch cabinet.

[0031] A first interlocking baffle 250 is also provided between the operating hole protective cover 240 and the first extension plane. It should be noted that the first interlocking baffle 250 can realize the control of the interlocking state of the switch cabinet. Through the linkage of the connecting rod and other devices, it can be ensured that the load switch device 200 of the switch cabinet operates in the correct order, avoids misoperation and accidental triggering, and ensures the safety of equipment and personnel. By setting the first interlocking baffle 250, the operation of the equipment or machinery at different positions can be accurately monitored. When the connecting rod is subjected to external force, the position of the baffle changes, thereby providing accurate feedback on the position of the equipment. The first interlocking baffle 250 can also be used for the safety protection of the equipment. For example, when the switch cabinet is in operation, when the first interlocking baffle 250 detects that the load switch device 200 or the load switch motor 300 exceeds the safety range or an abnormal situation occurs, it can trigger an alarm or shutdown and other measures to protect the safety of the operator and equipment. The first interlocking baffle 250 can also prevent misoperation and accidental triggering. Only after the specific operation steps are completed, the connecting rod can be subjected to external force, so that the load switch device 200 switches the switch state to achieve unlocking or locking of the device.

[0032] The load switch motor 300 is also provided with an operating shaft 310 , a program lock cam 320 and a program lock limit plate 330 . The program lock cam 320 is sleeved on the outer surface of the operating shaft 310 . The program lock is installed on one side of the program lock cam 320 and connected to the second mounting plate 130 .

[0033] It should be noted that the operating shaft 310 is used to provide a reliable mechanical connection method to ensure the accuracy and consistency of the switching action of the load switch motor 300. At the same time, the design of the operating shaft 310 is also convenient for manual operation or automatic control, which improves the operability and convenience of the five-protection interlocking mechanism.

[0034] The load switch device 200 is also provided with a limit device 260, which includes a transmission shaft limit ring 261, a first limit piece 262 and a second interlocking baffle 263. The first limit piece 262 and the transmission shaft limit ring 261 are sleeved on the drive shaft, and the transmission shaft limit ring 261 is provided with a second extension plane 264. One end of the first limit piece 262 is connected to the second extension plane 264, and the other end of the first limit piece 262 is connected to the second interlocking baffle 263. It should be noted that the first limit piece 262 is connected to the transmission shaft limit ring 261, one end is connected to the second extension plane 264, and the other end is connected to the second interlocking baffle 263. When the load switch device 200 is operated, the connection between the first limit piece 262 and the second extension plane 264 limits the state of the second interlocking baffle 263, thereby realizing the monitoring and control of the stroke of the load switch device 200. The travel range of the load switch device 200 is accurately controlled by the limit device 260 to ensure that the load switch device 200 operates within a safe range. The limit device 260 can effectively prevent the load switch device 200 from exceeding the specified travel range, avoid accidents in the five-defense interlocking mechanism, and further improve the safety of the five-defense interlocking mechanism. The connection between the first limit plate 262 and the second interlocking baffle 263 realizes the monitoring of the state of the load switch device 200, and can affect the state of the second interlocking baffle 263, thereby realizing the interlocking function of the switch cabinet and ensuring the normal operation and coordinated operation of the five-defense interlocking mechanism.

[0035] The load switch device 200 is provided with an electromagnetic lock 340 and an electric test lock 350. The electromagnetic lock 340 is provided with an electromagnetic lock plate 341. The electromagnetic lock plate 341 is provided with a first groove 352. The electromagnetic lock 340 is connected to the electric test lock 350. One end of the electromagnetic lock plate 341 is connected to the electric test lock 350. The operating hole protective cover 240 is provided with a limiting protrusion 231. The other end of the electromagnetic lock plate 341 is connected to the limiting protrusion 231 through the first groove 352.

[0036] It should be noted that a limiting protrusion 231 is provided on the operating hole protective cover 240, and the other end of the electromagnetic lock 340 locking piece is connected to the limiting protrusion 231 through the first groove 352. When the operating hole protective cover 240 is opened, the electromagnetic lock 340 locking piece is limited by the first groove 352 and the limiting protrusion 231, thereby maintaining a locked state. The provision of the electromagnetic lock 340 and the electric test lock 350 enhances the safety of the load switch device 200. Only after a specific operating step is completed, the electromagnetic lock 340 can be released to release the locking state of the electric test lock 350, thereby allowing the operating hole protective cover 240 to be opened. Prevent misoperation and accidental triggering of the five-protection interlocking mechanism to ensure the safety of equipment and personnel. The first groove 352 of the electromagnetic lock locking piece 341 is connected to the limiting protrusion 231 on the operating hole protective cover 240, thereby monitoring the state of the operating hole. Only when the operating hole protective cover 240 is completely closed, the limiting protrusion 231 can be completely inserted into the first groove 352, indicating that the operating hole is in a normally closed state. The interlocking relationship between the electromagnetic lock 340 and the electric test lock 350 can ensure that the load switch device 200 is operated in the correct operating sequence. Only when the electromagnetic lock plate 341 is released, the electromagnetic lock 340 can be unlocked, thereby allowing the operating hole protective cover 240 to be opened. Avoid incorrect operating sequences and ensure the normal operation of the five-protection interlocking mechanism.

[0037] A plurality of travel switches are arranged at the bottom of the front wall of the second mounting plate 130. It should be noted that the travel switch is an electromechanical device, which is usually composed of contacts and a joystick. When the joystick is subjected to an external force, the contact will switch the state, thereby realizing the switch control of the signal. A plurality of travel switches are arranged at the bottom of the front wall of the second mounting plate 130, and the operation state of the five-defense interlocking mechanism can be monitored and controlled according to the force conditions of the joystick at different positions. By setting a plurality of travel switches, the operation of the load switch device 200 at different positions can be accurately monitored. When the operating rod is subjected to an external force, the state of the travel switch will change, thereby providing accurate feedback on the switch state of the five-defense interlocking mechanism. The travel switch can generate a switch signal according to the change of its state, which can be used for the start and stop, steering or position adjustment of the load switch device 200. The travel switch can also be used for the safety protection of the five-defense interlocking mechanism. For example, when the five-defense interlocking mechanism is running, when the travel switch detects that the equipment exceeds the safety range or an abnormal situation occurs, it triggers an alarm or shutdown and other measures to protect the safety of the operator and the switch cabinet.

[0038] A third interlocking baffle is also provided at the bottom of the operating shaft 310, the program lock cam 320 and the program lock limit plate 330. It should be noted that the third interlocking baffle is provided at the bottom of the operating shaft 310, the program lock cam 320 and the program lock limit plate 330 to limit the rotation position of the program lock cam 320. By limiting the rotation angle of the program lock wheel, the program lock cam 320 is prevented from over-rotating, thereby causing the five-prevention interlocking mechanism to have a misoperation. In addition, the third interlocking baffle can simplify the maintenance process, and the staff can intuitively observe the positional relationship between the program lock cam 320 and the third interlocking baffle, thereby reducing the maintenance cost and downtime of the switch cabinet.
