[0025] The controller 18 is used for controlling and monitoring the state of the electrical elements 3 in the circuit breaker cabinet, and the controller 18 is arranged on the front side of the cabinet door 17 to facilitate the real-time monitoring and adjustment of the equipment state by the operating personnel, and some basic operations can be performed without opening the cabinet door 17. The cabinet door 17 is fixedly connected with a handle 19 on one side below, and this design makes it more convenient to open and close the cabinet door 17. The bottom of the cabinet 1 is fixedly connected with a base 20, which not only provides stable support but also plays a protective role to prevent ground moisture or small particles from entering the inside of the cabinet 1 and affecting the work of the electrical elements 3.

[0026] Further, the inside of the mounting shell 7 is slidably connected with a lifting block 8, and the front center of the lifting block 8 is rotatably connected with an inclined fixed sleeve 5, and one end of the push rod 4 away from the mounting plate 2 extends into the fixed sleeve 5 and is in sliding connection with the same.

[0027] The lifting block 8 slidably connected inside the mounting shell 7 allows it to be adjusted along the vertical direction, and the position of the lifting block 8 can be controlled to change the inclination angle of the push rod 4. The front center of the lifting block 8 is rotatably connected with an inclined fixed sleeve 5, and one end of the push rod 4 away from the mounting plate 2 extends into the fixed sleeve 5 and is in sliding connection with the same.

[0030] Further, the lifting block 8 is internally provided with a lifting threaded rod 9, the bottom of the lifting threaded rod 9 is rotatably connected between the top of the cabinet 1, the top of the lifting threaded rod 9 extends above the top of the mounting shell 7 and is rotatably connected thereto, the top of the mounting shell 7 is fixedly connected with a power motor 10, the bottom output end of the power motor 10 is fixedly connected with the top of the lifting threaded rod 9.

[0031] The bottom of the lifting threaded rod 9 is rotatably connected between the top of the cabinet 1, ensuring that it can rotate freely without displacement, and the top of the lifting threaded rod 9 extends above the top of the mounting shell 7 and is rotatably connected thereto, ensuring the stability of the lifting threaded rod 9 when rotating.

[0032] The top of the mounting shell 7 is fixedly connected with a power motor 10, and the bottom output end of the power motor 10 is fixedly connected with the top of the lifting threaded rod 9. When the power motor 10 is started, it will drive the lifting threaded rod 9 to rotate. Since the lifting block 8 is threadedly connected with the lifting threaded rod 9, as the lifting threaded rod 9 rotates, the lifting block 8 will move up and down.

[0033] The end of the push rod 4 away from the mounting plate 2 extends into the fixed sleeve 5 and is slidably connected therewith, and the fixed sleeve 5 is rotatably connected with the lifting block 8. When the lifting block 8 moves up and down, it will drive the push rod 4 to change the angle and length, thereby pushing or pulling the mounting plate 2 to move forward and backward.

[0034] Further, the power motor 10 is externally provided with a protective cover 11, the bottom of the protective cover 11 is fixedly connected with the top of the mounting shell 7, the top of the inner wall of the mounting shell 7 and the top of the cabinet 1 are fixedly connected with a lifting limiting rod 12, and the lifting block 8 is slidably connected with the lifting limiting rod 12.

[0035] The protective cover 11 can protect the power motor 10 from external environmental factors such as dust, moisture, etc., prolong the service life of the motor, and also improve the safety of operation, preventing accidental contact with rotating parts. The lifting limiting rod 12 serves to provide a stable guide path for the lifting block 8, ensuring that it does not deviate or tilt during the up and down movement, ensuring the stability and accuracy of the lifting action.

[0036] Further, the rear side of the mounting plate 2 is provided with a fixed rod 13, the top and bottom of the fixed rod 13 are fixedly connected with the top and bottom of the inner wall of the cabinet 1 respectively, and the surface of the fixed rod 13 is slidably connected with a sliding sleeve 14 correspondingly at the top and bottom. The two sliding sleeves 14 are rotatably connected with the two spring dampers 15 arranged obliquely near the side of the mounting plate 2.

[0037] Further, the two spring dampers 15 are rotatably connected between the rear side of the mounting plate 2 and the ends of the two sliding sleeves 14 away from each other. The surface of the fixed rod 13 is movably sleeved with a second spring 16 at the top and bottom. The two second springs 16 are fixedly connected between the side of the two sliding sleeves 14 away from each other and the ends of the two second springs 16 away from each other. The ends of the two second springs 16 away from each other are fixedly connected with the top and bottom of the inner wall of the cabinet 1.

[0038] When the mounting plate 2 moves forward and backward, the spring damper 15 can absorb and alleviate the vibration, reducing the influence on the electrical components 3. The surface of the fixed rod 13 is movably sleeved with a second spring 16 at the top and bottom. The two second springs 16 are fixedly connected between the side of the two sliding sleeves 14 away from each other and the ends of the two second springs 16 away from each other. The ends of the two second springs 16 away from each other are fixedly connected with the top and bottom of the inner wall of the cabinet 1. This arrangement allows the second spring 16 to provide additional cushioning and support when the sliding sleeve 14 moves up and down.

[0039] In the initial state, the mounting plate 2 is located at the rear side of the cabinet 1, the electrical components 3 are fixed on the front side of the mounting plate 2, the power motor 10 is in a static state, the lifting threaded rod 9 is not rotating, the lifting block 8 is located at a certain preset height position, the sliding sleeve 14 is located on the fixed rod 13, the spring damper 15 is rotatably connected with the sliding sleeve 14 and the mounting plate 2, and the second spring 16 is in a natural state or a slightly compressed state.

[0040] When it is necessary to pull out the mounting plate 2 for maintenance, the power motor 10 is started to drive the lifting threaded rod 9 to rotate. Since the lifting block 8 is threadedly connected with the lifting threaded rod 9, as the lifting threaded rod 9 rotates, the lifting block 8 starts to move up and down. The up and down movement of the lifting block 8 changes the position of the fixed sleeve 5, which in turn adjusts the angle of the obliquely arranged push rod 4 through the fixed sleeve 5. One end of the push rod 4 is rotatably connected with the center top of the rear side of the mounting plate 2, the other end extends into the fixed sleeve 5 and is slidably connected with the fixed sleeve 5, and the push rod 4 is internally provided with a first spring 6 to provide a buffering effect. As the fixed sleeve 5 moves up and down, the angle of the push rod 4 changes, pushing the mounting plate 2 to slide from the inside to the outside of the cabinet 1. The sliding blocks 201 at the top and bottom centers of the mounting plate 2 slide along the sliding grooves 101 at the top and bottom of the inner wall of the cabinet 1, ensuring that the mounting plate 2 can move smoothly forward and backward. In this process, the sliding sleeve 14 on the fixed rod 13 also moves up and down accordingly. The spring damper 15 and the second spring 16 work together to absorb any vibration or impact that may occur, ensuring smooth movement of the mounting plate 2.

[0041] The above merely preferred embodiments of the present application are not used to limit the present application, and any modification, equivalent replacement and improvement etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
