[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3, the utility model provides an embodiment: a high-voltage cabinet that is easy to maintain, including a cabinet body 1, a cooling fan 2 is fixedly connected inside the cabinet body 1, a dust cover 3 is arranged on the upper surface of the cabinet body 1, and the dust cover 3 covers the outer wall of the cooling fan 2, a protective door 4 is rotatably connected to the outer wall of the cabinet body 1, a connecting frame 5 is slidably connected to the outer wall of the protective door 4, a dust net 6 is fixedly connected to the inner wall of the connecting frame 5, a fixing box 7 is fixedly connected inside the connecting frame 5, a limit rod 8 is fixedly connected to the inner wall of the fixing box 7, a spring 9 is sleeved on the outer wall of the limit rod 8, and a sliding plate 10 is fixedly connected to both ends of the spring 9, and the outer wall of the sliding plate 10 is slidably connected to the inner wall of the fixing box 7, and a clamping assembly is arranged on the outer wall of the sliding plate 10; the clamping assembly includes a clamping block 1101, one side of the outer wall of the clamping block 1101 is fixedly connected to one side of the outer wall of the sliding plate 10, and the other side of the outer wall of the clamping block 1101 is slidably connected to the inner wall of the protective door 4, and one side of the outer wall of the sliding plate 10 is fixedly connected to a handle 1102;

[0024] Specifically, when it is necessary to heat the electrical components 18 inside the cabinet 1, the function of the cooling fan 2 is to guide the external cold air into the cabinet 1. The cold air can effectively prevent dust and other impurities from entering the cabinet 1 through the filtering effect of the dust cover 3, thereby protecting the electrical components 18. The cold air filtered by the dust cover 3 will be discharged through the dust net 6 on the inner wall of the protective door 4. This design allows the fresh air to be directly transmitted to the surface of the electrical components 18 inside the cabinet 1, thereby achieving the effect of cooling and heat dissipation. When the dust net 6 needs to be removed, the sliding plate 10 can be operated by pressing the handle 1102. Under the action of pressing the handle 1102, the sliding plate 10 will squeeze the spring 9 and shrink it. As the spring 9 shrinks, the sliding plate 10 will limit the movement on the outer wall of the limit rod 8. This limiting movement enables the sliding plate 10 to drive the block 1101 to detach from the inside of the protective door 4. When the block 1101 detaches from the inside of the protective door 4, the connecting frame 5 can be easily removed. This design enables maintenance personnel to quickly and conveniently disassemble and repair the connection frame 5, thereby improving work efficiency and convenience.

[0025] Reference Figure 1 and 4 A slide rail 12 is fixedly connected to the bottom of the inner wall of the cabinet 1, and a slider 13 is slidably connected to the outer wall of the slide rail 12; a support plate 14 is fixedly connected to the upper surface of the slider 13, an electrical component 18 is fixedly connected to one side of the outer wall of the support plate 14, and a rack 15 is fixedly connected to the lower surface of the support plate 14; a motor 16 is fixedly connected to the bottom of the inner wall of the cabinet 1, and a gear 17 is fixedly connected to the output end of the motor 16, and the gear 17 is meshed with the rack 15;

[0026] Specifically, when the electrical component 18 needs to be repaired, the motor 16 is started, and the motor 16 starts to rotate by driving the gear 17. This rotation causes the gear 17 to mesh with the rack 15, thereby realizing the linkage rotation of the gear 17 and the rack 15. The rotation of the rack 15 further drives the slider 13 below it to slide outside the slide rail 12. This sliding effect causes the slider 13 on the lower surface of the support plate 14 to move along the slide rail 12. Thus, the effect of sending the support plate 14 out is achieved.

[0027] Reference Figure 1 and 4 A limit rod 19 is fixedly connected to one side of the inner wall of the cabinet 1, and a limit block 20 is fixedly connected to one end of the limit rod 19; a connecting frame 21 is fixedly connected to the upper surface of the support plate 14, and a concave wheel 22 is rotatably connected to the outer wall of the connecting frame 21; the outer wall of the concave wheel 22 is slidably connected to the outer wall of the limit rod 19;

[0028] Specifically, as the slider 13 moves, the outer wall concave wheel 22 of the connecting frame 21 performs limiting movement on the outer wall of the limiting rod 19. This limiting movement ensures the stable connection and precise position control between the connecting frame 21 and the limiting rod 19, providing a stable and accurate operating environment for maintenance work. With the assistance of the support plate 14, the electrical component 18 is smoothly sent out of the cabinet 1. This process not only simplifies the operating steps, but also enables the electrical component 18 to be conveniently sent out from the narrow space inside the cabinet 1, providing convenience for subsequent maintenance work.

[0029] Working principle: when it is necessary to dissipate heat for the electrical components 18 inside the cabinet 1, the cooling fan 2 is started so that the external cold air is filtered through the dust cover 3 and enters the cabinet 1, and then is discharged through the dust net 6 on the inner wall of the protective door 4, thereby achieving the effect of transmitting fresh air to the surface of the electrical components 18 inside the cabinet 1 for cooling and heat dissipation. At this time, by pressing the handle 1102, the sliding plate 10 squeezes the spring 9 to contract, thereby achieving the effect of limiting the movement of the sliding plate 10 on the outer wall of the limiting rod 8. At this time, the sliding plate 10 drives the block 1101 to separate from the inside of the protective door 4, thereby facilitating the quick connection of the connection frame 5. Quick disassembly can achieve the effect of fast and convenient maintenance. When the electrical component 18 needs to be repaired, the gear 17 is driven to rotate by starting the motor 16, so as to achieve the effect of driving the gear 17 to engage and rotate with the rack 15. The slider 13 on the lower surface of the support plate 14 is driven by the rack 15 to slide outside the slide rail 12, so as to achieve the effect of driving the outer wall concave wheel 22 of the connecting frame 21 to move in a limited manner on the outer wall of the limiting rod 19, and the electrical component 18 is sent out of the cabinet 1 through the support plate 14, so as to achieve the effect of sending the electrical component 18 out of the narrow space inside the cabinet 1 for maintenance work.
