When the equipment needs to be disassembled and repaired, the control switch 10 is started to electrify the contact switch 707, after the main cabinet door is slightly opened, the chamber door 2 provided with the locking mechanism is opened together, the positioning plate 701 is gradually separated from the abutting block 704, the compression spring 705 compressed by force is gradually loosened to drive the limiting rod 702 to rebound, so that the two separating plates 3 are not locked by the limiting rod 702 any more, the two separating rods are in a movable state, and along with the contact of the rebound limiting plate 706 of the limiting rod 702 with the contact switch 707, the electric push rod 801 is started to drive the transverse moving rod 803 to transversely move for a certain distance to enable the bevel gear B609 to be meshed with the bevel gear A608; when the main cabinet door is opened, the rotating rod 601 rotates to drive the chain wheel A602 to rotate, the chain 607 drives the chain wheel B606 to rotate, the bevel gear A608 rotates along with the chain wheel B606 and drives the bevel gear B609 to rotate, the square 805 is inserted into the square 804, so that the bevel gear B609 can drive the square 805 and the bidirectional screw 604 to rotate through the square 804 while rotating, the connecting plates 603 in threaded connection with two different thread sections of the bidirectional screw 604 are driven to be away from each other, and the rear plate 4 is away along with the connecting plates 603 and provides a space for moving out the separating plate 3.

One of the separation plates 3 is gradually pulled out from one end of the opened main cabinet door, the hobbing at the bottom of the separation plate 3 drives the engaging gear 902 and the driving gear 903 to rotate along with the dragging of the separation plate 3, the other separation plate 3 moves in the reverse direction, namely moves towards the direction of the rear plate 4 due to the matching of the two engaging gears 902, the other separation plate 3 can continuously and automatically move while one of the separation plates 3 is dragged through the matching of the transmission belts 904 until the two separation plates 3 are separated from the cabinet body 1, and then the internal components can be maintained in the wide space in the cabinet body 1; the device is not obstructed by other parts such as separation chambers during maintenance, provides larger maintenance space for convenient maintenance, is convenient for disassembling equipment, has stable structure when in a non-disassembling state, and effectively solves the problems of inconvenient maintenance and difficult disassembly.
