[0002] Intelligent electrical cabinets are power equipment that integrates advanced sensing, control, and communication technologies. They are widely used in power distribution, industrial control, and other fields. By introducing technologies such as multi-sensor collaborative detection, mechanical interlocking, and remote monitoring, they can achieve precise control, fault early warning, and efficient operation and maintenance, thereby improving the reliability and safety of power systems.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0019] According to one embodiment of the present invention, in conjunction with Figure 1 as well as Figure 3 The diagram shows an intelligent high-voltage switchgear with dual confirmation function, including a cabinet 1, a handcart body 4 inside the cabinet 1, a front micro switch assembly 3 and a middle double micro switch assembly 2 for determining the position of the handcart body 4 fixedly connected to the inner wall of the cabinet 1, and a locking assembly 5 for locking the handcart body 4 inside the cabinet 1.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Combination Figures 1-5 The middle dual micro switch assembly 2 has the same structure as the front micro switch assembly 3. The middle dual micro switch assembly 2 includes an outer shell 21 fixedly connected to the inner wall of the cabinet 1. A contact switch 22 is fixedly connected to the inner wall of the outer shell 21. The contact switch 22 is connected to an external power supply. A guide rod 23 is fixedly connected to the inner wall of the outer shell 21. An elastic contact piece 24 is provided on one side of the contact switch 22. A through groove 241 is opened on one side of the elastic contact piece 24. The guide rod 23 passes through the through groove 241. A wedge-shaped... When the handcart is fully inserted, the wedge-shaped rod 25 is pressed against the side wall of the handcart, causing the elastic contact piece 24 to move downward and trigger the contact switch 22. The guide rod 23 ensures that the elastic contact piece 24 moves downward stably. The middle double micro switch assembly 2 is correspondingly set in the middle of the handcart body 4, and the front micro switch assembly 3 is correspondingly set at the end of the handcart body 4. Through the setting of the middle double micro switch assembly 2 and the front micro switch assembly 3, dual position detection is realized after the handcart body 4 is inserted, ensuring that the handcart body 4 moves accurately to the predetermined position.

[0022] A return spring 26 is provided on the bottom surface of the elastic contact piece 24. One end of the return spring 26 is fixedly connected to the inner wall of the outer shell 21, and the other end of the return spring 26 is fixedly connected to the bottom surface of the elastic contact piece 24. The return spring 26 is used to automatically reset the position of the elastic contact piece 24 when the handcart is withdrawn.

[0023] A rubber buffer head 251 is fixedly connected to one end of the wedge rod 25. The rubber buffer head 251 provides buffer protection and reduces wear.

[0024] The locking assembly 5 includes a turntable 51 located on one side of the cabinet 1. A bidirectional threaded rod 52 is fixedly connected to one side of the turntable 51. One end of the bidirectional threaded rod 52 is rotatably connected to the inner wall of the cabinet 1. A connecting short plate 53 is threadedly connected to the outer side of the bidirectional threaded rod 52. Two sets of connecting short plates 53 are provided, symmetrically arranged. A limiting groove is provided on the bottom surface of the inner wall of the cabinet 1. The connecting short plate 53 is slidably connected inside the limiting groove. A clamping plate 54 is fixedly connected to the upper surface of the connecting short plate 53. The handcart body 4 is positioned between the clamping plates 54. After the handcart body 4 moves to the corresponding position, the turntable 51 is manually rotated, causing the bidirectional threaded rod 52 to rotate. Under the limiting action of the limiting groove, the connecting short plate 53 and the clamping plate 54 move towards the center, thereby achieving the clamping and locking operation of the handcart body 4.

[0025] A polyurethane coating 55 is provided on one side of the clamp 54, which enhances the locking stability during fixation.

The handcart guide rail 6, the rotating rod 61 and the roller 62, together with the guide rail groove 41, ensure the stability of the handcart body 4 during movement.

[0027] In this embodiment, when the handcart is fully inserted, the side wall of the handcart body 4 presses against the wedge rod 25, causing the elastic contact piece 24 to move downward and trigger the contact switch 22. The guide rod 23 ensures that the elastic contact piece 24 moves downward stably. Through the setting of the middle double micro switch assembly 2 and the front micro switch assembly 3, dual position detection is realized after the handcart body 4 is inserted. Then, the turntable 51 is manually rotated, which drives the bidirectional threaded rod 52 to rotate. Under the limiting action of the limiting groove, the connecting short plate 53 and the clamping plate 54 move closer to the middle, realizing the clamping and locking of the handcart body 4, thereby ensuring that the handcart body 4 moves accurately to the predetermined position and reducing the misjudgment rate.
