[0023] The motor 11 changes the wiring sequence of any two-phase power supply, the direction of the rotating magnetic field is reversed, and the rotor is reversed under the action of electromagnetic force, realizing the forward and reverse rotation of the motor, thereby realizing the forward and backward movement of the switch cabinet 2.

[0024] The working principle of the motor 11 and the limit stop 14 is as follows: 1. Motor drive: change the phase sequence of the three-phase power supply through the contactor to control the forward / reverse rotation of the motor 11 to drive the switch cabinet 2 to move forward / backward.

[0025] 2. Limit trigger: when the switch cabinet 2 moves to the preset stroke end point, it will touch the limit stop 14 in the corresponding direction.

[0026] 3. Signal feedback: after the limit stop 14 is triggered, a disconnection signal is output to the control loop.

[0027] 4. Safety shutdown: the control loop cuts off the power supply of the contactor in that direction, and the motor 11 stops running in that direction, while the other direction remains operable.

[0028] The monitoring camera 210 collects images inside the box through an industrial-grade camera module, and is linked with environmental sensors to transmit data in real time and provide early warning of abnormalities, realizing remote visual monitoring of the switch cabinet 2.

[0029] Please refer to Figure 1 , the upper end of the support shaft 16 is slidably connected to the sliding base 15, and the inside of the sliding base 15 is slidably sleeved with the guide rod 13;

[0030] Under such a setting, the motor 11 is started to drive the threaded shaft 12 to rotate, thereby driving the sliding base 15 to move horizontally, facilitating the extraction of the switch cabinet 2 for inspection and repair by maintenance personnel.

[0031] Please refer to Figure 1 , the inside of the base 1 is slidably connected to the threaded shaft 12, and the inside of the sliding base 15 is threadedly connected to the threaded shaft 12;

[0032] In such a setting, when the switch cabinet 2 moves to the ends of the base 1, it will touch the limit stop 14, the internal structure of the limit stop 14 disconnects the power supply, and the motor 11 stops working, thereby effectively preventing the switch cabinet 2 from moving excessively and colliding with the ends of the base 1.

[0033] Please refer to Figures 1-2 , the inner side of the nut 29 abuts against the shaft support 27, and the inner side of the shaft support 27 is slidingly connected with the monitoring camera 210;

[0034] In such a setting, by starting the driver 22 to drive the support rod 23, the auxiliary support 24 and the monitoring camera 210 to rotate 90 degrees, and rotating to adjust the monitoring angle of the monitoring camera 210, and rotating the nut 29 to press the shaft support 27, the situation of the switch cabinet 2 can be monitored in real time, the frequency of manual inspection can be reduced, and faults can be timely warned.

[0035] Please refer to Figures 1-2 , the upper end surface of the switch cabinet 2 is slidingly connected with the auxiliary support 24, and the ball 25 is slidingly sleeved in the sliding groove 26;

[0036] In such a setting, the design of the auxiliary support 24 can strengthen the support of the support rod 23, preventing the end of the support rod 23 from sagging due to long-term use.

[0037] The working principle of the embodiment is as follows: the sliding and drawing type switch cabinet is driven by the motor 11 to rotate the threaded shaft 12, thereby driving the sliding base 15 to move horizontally, facilitating the drawing of the switch cabinet 2 for maintenance personnel to check and maintain the switch cabinet 2. When the switch cabinet 2 moves to the ends of the base 1, it will touch the limit stop 14, the internal structure of the limit stop 14 disconnects the power supply, and the motor 11 stops working, thereby effectively preventing the switch cabinet 2 from moving excessively and colliding with the ends of the base 1. The design of the support shaft 16 can support the sliding base 15 and assist the sliding movement of the sliding base 15, preventing the sliding base 15 from directly contacting the bottom of the base 1 and causing wear and tear.

[0038] By starting the driver 22 to drive the support rod 23, the auxiliary support 24 and the monitoring camera 210 to rotate 90 degrees, and rotating to adjust the monitoring angle of the monitoring camera 210, and rotating the nut 29 to press the shaft support 27, the situation of the switch cabinet 2 can be monitored in real time, the frequency of manual inspection can be reduced, and faults can be timely warned.
