Technical Field
[0001] This utility model relates to the field of power distribution cabinet protection technology, and in particular to an intelligent power distribution cabinet electrical safety protection device. Background Technology
[0002] With the rapid advancement of smart grid construction, distribution cabinets, as key equipment in the power system, directly impact power supply reliability and operation and maintenance efficiency through their safety protection performance. In complex environments such as substations and industrial parks, distribution cabinets not only need to cope with electrical fault risks but also withstand physical threats such as mechanical impacts and environmental corrosion. In particular, with the frequent occurrence of extreme weather events in recent years, the proportion of distribution cabinet failures caused by external impacts has increased significantly, and traditional protective structures are no longer sufficient to meet the stringent safety requirements of modern power systems.
[0003] The mainstream protective devices for current power distribution cabinets mainly adopt a structure of rigid frame combined with elastic padding. Typical designs include: an external support frame welded from channel steel, internal rubber buffer blocks, and bolt-fixed metal protective plates. The protective principle is to absorb impact energy through the deformation of the material itself. They mostly use a single rigid shell or a simple buffer structure, and absorb part of the collision energy by adding rubber strips to the corners or edges of the cabinet.
[0004] Existing protective devices suffer from insufficient impact energy dispersion. When subjected to high-speed impacts, the rigid protective structure directly transmits most of the impact force to the cabinet frame, absorbing only a small amount of impact energy. Therefore, an intelligent electrical safety protection device for distribution cabinets is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an intelligent electrical safety protection device for power distribution cabinets, which aims to improve the problem that when subjected to high-speed impact, the rigid protective structure will directly transmit most of the impact force to the cabinet frame and can only absorb a small amount of impact energy.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent electrical safety protection device for a power distribution cabinet, including a base, a sliding frame fixedly connected to the upper surface of the base, a power distribution cabinet body provided on the outer wall of the sliding frame, and a buffer component provided on the inner wall of the power distribution cabinet body;
[0007] The buffer assembly includes a buffer pad, a connecting plate three, and a disc spring. The outer wall of the buffer pad is fixedly connected to the inner wall of the power distribution cabinet body. The outer wall of the connecting plate three is fixedly connected to the inner wall of the buffer pad. The outer wall of the disc spring is fixedly connected to the inner wall of the power distribution cabinet body. A connecting seat two is fixedly connected to the inner wall of the connecting plate three and the buffer pad. A telescopic rod two is fixedly connected to the outer wall of the connecting seat two. A telescopic rod one is slidably connected to the inner wall of the telescopic rod two. A connecting seat one is fixedly connected to one end of the telescopic rod one. A telescopic spring is fixedly connected to the outer walls of the connecting seat one and the connecting seat two. A connecting plate two is fixedly connected to the outer wall of the connecting seat one. A protective plate is fixedly connected to the outer wall of the connecting plate two.
[0008] Furthermore, a support frame is fixedly connected to the outer wall of the power distribution cabinet body, and a connecting frame is fixedly connected to the outer wall of the support frame.
[0009] Furthermore, the outer wall of the connecting frame is slidably connected to the inner wall of the sliding frame, and a connecting plate is slidably connected to the inner wall of the sliding frame.
[0010] Furthermore, a connecting box is fixedly connected to the upper surface of the base, and a hydraulic cylinder is installed inside the connecting box. The output end of the hydraulic cylinder is fixedly connected to the lower surface of the connecting plate.
[0011] Furthermore, the outer wall of the connecting plate is fixedly connected to the inner wall of the connecting frame, and a fixing block and a connecting rod are fixedly connected to the upper surface of the base.
[0012] Furthermore, a connecting rod is rotatably connected to the inner wall of the fixed block, and a gear is fixedly connected to the outer wall of the connecting rod.
[0013] Furthermore, a third connecting rod is slidably connected to the inner wall of the second connecting rod, and one end of the third connecting rod is fixedly connected to the lower surface of the connecting plate.
[0014] Furthermore, the connecting rod three is meshed with the outer wall of the gear, and the outer wall of the gear is rotatably connected to the inner wall of the connecting rod two.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, the protective plate provides protection and buffering. Part of the impact force is buffered and released by the disc spring, and another part of the impact force is transmitted to the connecting plate 2, which drives the telescopic rod 1 to slide inside the telescopic rod 2. The telescopic spring is squeezed by the connecting seat 1 and the connecting seat 2, and then the impact force is transmitted to the buffer pad fixed to the connecting plate 3 for further buffering, thus achieving the effect of buffering and protection. This reduces the damage to the internal components of the power distribution cabinet caused by external force collisions, thereby improving the practicality of the device.
[0017] 2. In this utility model, the hydraulic cylinder drives the connecting plate to slide upward, causing the connecting frame to slide within the sliding frame. The groove in the connecting rod drives the gear to rotate, and the connecting rod causes the symmetrical gears on both sides to rotate simultaneously, making the connecting rod slide synchronously. This reduces the phenomenon of one side being higher than the other during the sliding process, avoids unilateral height deviation, and reduces the intrusion of ground moisture by adjusting the height of the distribution cabinet body, thereby improving the practicality of the device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figures 1-4 An embodiment of this utility model provides an intelligent electrical safety protection device for a power distribution cabinet, including a base 1, which serves as the basic support component of the entire protection device and bears the entire weight of the power distribution cabinet body 4 and the protection mechanism. A sliding frame 2 is fixedly connected to the upper surface of the base 1, the power distribution cabinet body 4 is provided on the outer wall of the sliding frame 2, and a buffer component is provided on the inner wall of the power distribution cabinet body 4.
[0028] The buffer assembly includes a buffer pad 12, a connecting plate 11, and a disc spring 10. The outer wall of the buffer pad 12 is fixedly connected to the inner wall of the distribution cabinet body 4. The buffer pad 12 is made of flexible material and absorbs impact energy through its own plastic deformation. It is the last level of protection in the buffer assembly and can further reduce the residual impact force, preventing the distribution cabinet body 4 from being subjected to hard impact. The outer wall of the connecting plate 11 is fixedly connected to the inner wall of the buffer pad 12, and the outer wall of the disc spring 10 is fixedly connected to the inner wall of the distribution cabinet body 4. The disc spring 10 absorbs impact energy through its own axial elastic deformation, reducing the load on subsequent buffer assemblies. A connecting seat 17 is fixedly connected between the connecting plate 11 and the inner wall of the buffer pad 12. When the extension spring 13 is compressed and deformed, the connecting plate 11 will absorb the residual impact energy. The remaining impact force is transmitted to the buffer pad 12, achieving secondary buffering and energy dissipation. A telescopic rod 16 is fixedly connected to the outer wall of the connecting seat 17. A telescopic rod 15 is slidably connected to the inner wall of the telescopic rod 16. A connecting seat 14 is fixedly connected to one end of the telescopic rod 15. A telescopic spring 13 is fixedly connected to the connecting seat 14 and the outer wall of the connecting seat 17. A connecting plate 9 is fixedly connected to the outer wall of the connecting seat 14. A protective plate 3 is fixedly connected to the outer wall of the connecting plate 9. The protective plate 3 is used to transmit the impact force to the disc spring 10 and other buffer components behind it. It disperses the impact energy through its own rigid structure and reduces the impact force directly acting on the cabinet. A support frame 5 is fixedly connected to the outer wall of the distribution cabinet body 4. A connecting frame 8 is fixedly connected to the outer wall of the support frame 5.
[0029] Reference Figures 1-6The outer wall of the connecting frame 8 is slidably connected to the inner wall of the sliding frame 2. A connecting plate 7 is slidably connected to the inner wall of the sliding frame 2. The sliding frame 2 provides a guide rail for the up-and-down sliding of the connecting frame 8, ensuring smooth sliding of the connecting frame 8 under the drive of the hydraulic cylinder 18 and preventing deviation or jamming during movement. A connecting box 6 is fixedly connected to the upper surface of the base 1. A hydraulic cylinder 18 is installed inside the connecting box 6. The output end of the hydraulic cylinder 18 is fixedly connected to the lower surface of the connecting plate 7. The outer wall of the connecting plate 7 is fixedly connected to the inner wall of the connecting frame 8. A fixing block 20 is fixedly connected to the upper surface of the base 1. Connecting rod 21 and connecting rod 19 are rotatably connected to the inner wall of fixing block 20. Fixing block 20 restricts the rotation trajectory of connecting rod 19 to prevent axial movement or swaying during transmission, ensuring the stability and synchronization of gear 23 transmission. Gear 23 is fixedly connected to the outer wall of connecting rod 19. Connecting rod 22 is slidably connected to the inner wall of connecting rod 21. One end of connecting rod 22 is fixedly connected to the lower surface of connecting plate 7. Connecting rod 22 and the outer wall of gear 23 are meshed with each other. The outer wall of gear 23 is rotatably connected to the inner wall of connecting rod 21.
[0030] Working principle: When electrical safety protection devices are needed to protect the distribution cabinet, if the distribution cabinet body 4 is impacted, the protective plate 3 will be the first to contact the impact force and buffer it. Part of the impact force is directly released through the elastic deformation of the disc spring 10, while the other part of the impact force is transmitted to the connecting plate 2 9, driving the telescopic rod 15 to slide within the telescopic rod 2 16. During this process, the telescopic spring 13 is elastically buffered by the compression of the connecting seat 14 and the connecting seat 2 17, and finally the residual impact force is transmitted to the buffer pad 12, which is fixedly connected to the connecting plate 3 11. The buffer pad 12 achieves secondary buffering through its flexible material, thereby effectively reducing the risk of damage to the internal components of the distribution cabinet body 4 caused by external impact. The support frame 5 is used for The hydraulic cylinder 18 inside the connecting box 6 can drive the connecting plate 7 to slide vertically. The connecting plate 7 drives the connecting frame 8 to slide smoothly within the sliding frame 2 fixed on the base 1. At the same time, the connecting rod 22 extends and retracts synchronously within the connecting rod 21. The groove structure inside the connecting rod 22 drives the gear 23 to rotate. Through the linkage of the connecting rod 19, the synchronous rotation of the symmetrical gears 23 on both sides is achieved, ensuring that the connecting rod 22 remains horizontal and synchronous during the sliding process, avoiding unilateral height deviation. The fixing block 20 further ensures the stability of the mechanism by limiting the rotation trajectory of the connecting rod 19, adjusting the height of the distribution cabinet body 4, and reducing the intrusion of ground moisture.
