[0015] Preferably, the base is provided with a roller on both sides.

[0016] The front end of the base is provided with a waist-shaped through hole on both sides;

[0017] A handle is slidingly inserted into the waist-shaped through hole, one end of the handle extends into the front end of the base, a transverse plate is slidingly arranged in the front end of the base, one end of the transverse plate penetrates through one side of the base, and the transverse plate is fixedly connected with the handle.

[0018] Compared with the prior art, the circuit breaker moving mechanism has the following advantages:

[0019] (1) By arranging the circuit breaker moving mechanism in the circuit breaker chamber, the moving seat is moved by operating the lead screw on the circuit breaker moving mechanism, so that the movement of the circuit breaker can be quickly and effectively realized, and the circuit breaker connector is connected or disconnected;

[0020] (2) Simple structure, convenient to use. BRIEF DESCRIPTION OF DRAWINGS

[0021] Figure 1 It is a structural schematic view of a circuit breaker moving mechanism of the embodiment;

[0022] Figure 2 It is a structural schematic view of the base in the circuit breaker moving mechanism of the embodiment. DETAILED DESCRIPTION

[0023] The utility model will be further described below in combination with the drawings and specific embodiments.

[0024] As shown in Figure 1 and Figure 2 , a circuit breaker moving mechanism comprises a base 1, a lead screw 2, a moving seat 3 and a circuit breaker 4; the base 1 is arranged in the circuit breaker chamber in the central control cabinet; the lead screw 2 is horizontally rotationally arranged on the base 1 and is arranged along the moving direction of the circuit breaker 4; the moving seat 3 is threadedly sleeved on the lead screw 2; the circuit breaker 4 is installed on the moving seat 3; the outer end of the lead screw 2 is provided with a jack (not shown in the figure), so that the external staff can rotate the lead screw 2 by means of a tool, thereby enabling the moving seat 3 to move linearly on the lead screw 2.

[0025] In the embodiment, as shown in Figure 2 , the base 1 is further provided with a guide rod 5, and the moving seat 3 is slidingly arranged on the guide rod 5, effectively ensuring that the moving seat 3 does not shake when moving, and ensuring that the circuit breaker 4 can be accurately inserted into the circuit breaker connector.

[0026] Further, the guide rod 5 is provided with a stop rod 6 near both ends, which effectively limits the stroke of the moving seat 3 and avoids damaging the circuit breaker jack by the circuit breaker 4.

[0027] Furthermore, a buffer spring 7 is sleeved on the inner end of the guide rod 5. The buffer spring 7 is located between the stop bar and the inner end of the guide rod 5. When the inner stop bar is damaged, the buffer spring 7 can play a buffering role to prevent the circuit breaker from crushing the circuit breaker connector.

[0028] In this embodiment, as Figure 2 As shown, rollers 8 are provided on both sides of the base 1; a waist-shaped through hole 9 is provided horizontally on both sides of the front end of the base 1; a handle 10 is slidably inserted into the waist-shaped through hole 9, one end of the handle 10 extends into the front end of the base 1, and a horizontal plate 11 is slidably provided in the front end of the base 1, one end of the horizontal plate 11 protrudes out of one side of the base 1, and the horizontal plate 11 is fixedly connected to the handle 10; with this configuration, when it is necessary to move the base 1 out of the circuit breaker compartment 2, the position of the handle 10 on the waist-shaped through hole 9 is moved horizontally, so that one end of the horizontal plate 11 extends into the front end of the base 1, and the base 1 can be moved outward, which is convenient for maintenance personnel.

[0029] When it is necessary to move the circuit breaker 4, a tool is inserted into the socket at the outer end of the lead screw 2, the lead screw 2 is rotated, and the moving seat 3 moves inward until the circuit breaker 4 is connected to the circuit breaker connector. The guide rod 5 guides the moving seat to prevent it from shaking, and the stops at both ends effectively limit the travel of the moving seat to ensure that the circuit breaker is accurately and properly connected to the circuit breaker connector.

[0030] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
