Description

Technical Field

[0001] This utility model relates to a switch cabinet assembly, specifically an intelligent switch cabinet assembly for railways, and belongs to the technical field of switch cabinet assembly. Background Technology

[0002] In railway power systems, switchgear, as a core power distribution device, plays a crucial role in power distribution, circuit protection, and equipment control. It integrates precision electrical components such as circuit breakers, disconnect switches, instrument transformers, and relay protection devices. It needs to operate stably in complex and ever-changing outdoor environments. The railway system has extremely high requirements for power supply reliability. The protective performance of switchgear (such as waterproof, dustproof, and moisture-proof) directly affects power supply safety and equipment lifespan. Therefore, the structural design of switchgear must take into account functionality, durability, and environmental adaptability.

[0003] However, most existing switchgear components have various problems. For example, in the switchgear disclosed in announcement number CN107317252B, although it can reduce the motor starting load, in this technical solution and most current switchgear, to facilitate equipment maintenance, traditional switchgear usually has access ports on the side or top of the cabinet and is equipped with movable metal or composite material isolation plates. In the existing technology, the isolation plates are mostly linearly translated by a cylinder or motor-driven threaded rod inside the cabinet, and its movement trajectory remains parallel to the inner wall of the cabinet. However, this design has the following problems:

[0004] 1. Insufficient sealing: When the parallel-moving isolation plate is closed, it is difficult to form a tight fit with the edge of the maintenance opening. Especially after frequent opening and closing or wear of mechanical parts, millimeter-level gaps can easily form between the plate and the cabinet wall. The railway environment often faces the risk of rainwater, condensation, and dust intrusion. Such gaps can directly lead to moisture inside the switchgear, reduced insulation performance, and even short-circuit faults.

[0005] 2. High maintenance costs: Corrosion or insulation failure of internal components caused by seal failure requires frequent shutdowns for maintenance, which seriously affects the continuity of railway power supply and increases operation and maintenance costs. Utility Model Content

[0006] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing an intelligent switchgear component for railways.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An intelligent switchgear assembly for railways includes a switchgear side panel, an inspection port, and an isolation mechanism. The inspection port is disposed through the switchgear side panel, and the isolation mechanism is disposed on one side of the switchgear side panel.

[0009] The isolation mechanism includes a guide rail, a linkage frame, an isolation plate, a linkage rod, a drive assembly, and a fine-tuning assembly. The guide rail is fixed to one side of the switch cabinet side panel and two are symmetrically arranged. The linkage frame is slidably engaged between two adjacent guide rails. The isolation plate is connected to one side of the linkage frame and is located between the switch cabinet side panel and the linkage frame. The two ends of the linkage rod are rotatably connected between the linkage frame and the isolation plate, and are symmetrically arranged at the four corners of the linkage frame and the isolation plate.

[0010] The driving component is connected to the linkage frame, and the fine-tuning component is connected to the isolation plate.

[0011] As a further embodiment of this utility model: the drive assembly includes a rack, a transmission rod, and a gear. The rack is fixed at the center of the linkage frame. A protrusion is fixed on the side of the switch cabinet near the isolation mechanism. The transmission rod is rotatably connected to the protrusion. The gear is coaxially fixed on the transmission rod and meshes with the rack.

[0012] As a further embodiment of this utility model: the drive assembly further includes a worm gear, a servo motor, and a worm. The servo motor is fixed on the side plate of the switch cabinet, the worm is coaxially fixed on the output shaft of the servo motor, and the worm gear is coaxially fixed on the transmission rod and meshes with the worm.

[0013] As a further embodiment of this utility model: the fine-tuning component includes a fine-tuning plate and a guide wheel. The fine-tuning plate is fixed on the side plate of the switch cabinet, and an L-shaped slot is provided through the fine-tuning plate. The guide wheel is rotatably connected to the isolation plate and is located at the connection between the isolation plate and the linkage rod. The guide wheel is rolled and engaged in the slot on the fine-tuning plate.

[0014] As a further improvement of this utility model: a groove that cooperates with the isolation plate is provided on the side of the inspection port near the switch cabinet side plate, and a sealing gasket is provided in the groove.

[0015] As a further improvement of this utility model: pulleys are rotatably connected at the four corners of the linkage frame, and the pulleys roll and abut against the guide rail.

[0016] The beneficial effects of this utility model are:

[0017] This patent addresses the issue of insufficient sealing of the inspection port isolation plate in intelligent railway switchgear by proposing an innovative structural design. Through the synergistic effect of gear and rack drive, self-locking mechanism, and fine-tuning component, the opening and closing efficiency and sealing performance of the inspection port are significantly improved. The gear and rack drive component replaces the traditional threaded rod structure, achieving rapid lateral sliding of the isolation plate through efficient conversion between linear and rotary motion, shortening the opening and closing time of the inspection port. This is particularly suitable for railway systems with high requirements for equipment maintenance efficiency, avoiding the jamming problem caused by mechanical delays in traditional cylinder or motor drives, and ensuring precise and controllable movement trajectory of the isolation plate. At the same time, the fine-tuning component drives the isolation plate to move laterally slightly, making it tightly fit with the edge of the inspection port, eliminating the gaps caused by traditional parallel movement, and completely solving the risks of water ingress and moisture. Furthermore, the fine-tuning component can adapt to the deformation of the switchgear caused by temperature changes or mechanical wear, maintaining a long-term sealing effect by automatically compensating for displacement deviations.

[0025] Example 1

[0026] like Figures 1 to 4As shown, an intelligent switchgear assembly for railways includes a switchgear side panel 1, an inspection port 2, and an isolation mechanism 3. The inspection port 2 is disposed through the switchgear side panel 1, and the isolation mechanism 3 is disposed on one side of the switchgear side panel 1.

[0027] The isolation mechanism 3 includes a guide rail 31, a linkage frame 32, an isolation plate 33, a linkage rod 34, a drive assembly, and a fine-tuning assembly. The guide rail 31 is fixed to one side of the switch cabinet side plate 1 and two are symmetrically arranged. The linkage frame 32 is slidably engaged between two adjacent guide rails 31. The isolation plate 33 is connected to one side of the linkage frame 32 and is located between the switch cabinet side plate 1 and the linkage frame 32. The two ends of the linkage rod 34 are respectively rotatably connected between the linkage frame 32 and the isolation plate 33 and are symmetrically arranged at the four corners of the linkage frame 32 and the isolation plate 33.

[0028] The drive assembly is connected to the linkage frame 32, and the fine-tuning assembly is connected to the isolation plate 33. The drive assembly includes a rack 35, a transmission rod 36, and a gear 37. The rack 35 is fixed at the center of the linkage frame 32. A protrusion is fixed on the side of the switch cabinet side plate 1 near the isolation mechanism 3. The transmission rod 36 is rotatably connected to the protrusion. The gear 37 is coaxially fixed on the transmission rod 36, and the gear 37 meshes with the rack 35.

[0029] The drive assembly also includes a worm gear 38, a servo motor 39, and a worm 310. The servo motor 39 is fixed on the side plate 1 of the switch cabinet, the worm 310 is coaxially fixed on the output shaft of the servo motor 39, and the worm gear 38 is coaxially fixed on the transmission rod 36 and meshes with the worm 310.

[0030] The fine-tuning component includes a fine-tuning plate 311 and a guide wheel 312. The fine-tuning plate 311 is fixed on the side plate 1 of the switch cabinet and has an L-shaped slot through it. The guide wheel 312 is rotatably connected to the isolation plate 33 and is located at the connection between the isolation plate 33 and the linkage rod 34. The guide wheel 312 is rolled and engaged in the slot on the fine-tuning plate 311.

[0031] This patent addresses the issue of insufficient sealing of the inspection port isolation plate in intelligent railway switchgear by proposing an innovative structural design. Through the synergistic effect of gear and rack drive, self-locking mechanism, and fine-tuning component, the opening and closing efficiency and sealing performance of the inspection port are significantly improved. The gear and rack drive component replaces the traditional threaded rod structure, achieving rapid lateral sliding of the isolation plate through efficient conversion between linear and rotary motion, shortening the opening and closing time of the inspection port. This is particularly suitable for railway systems with high requirements for equipment maintenance efficiency, avoiding the jamming problem caused by mechanical delays in traditional cylinder or motor drives, and ensuring precise and controllable movement trajectory of the isolation plate. At the same time, the fine-tuning component drives the isolation plate 33 to move laterally slightly, making it tightly fit with the edge of the inspection port 2, eliminating the gaps caused by traditional parallel movement, and completely solving the hidden dangers of water ingress and moisture. Furthermore, the fine-tuning component can adapt to the deformation of the switchgear caused by temperature changes or mechanical wear, maintaining a long-term sealing effect by automatically compensating for displacement deviations.

[0032] Example 2

[0033] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0034] The inspection port 2 has a groove that cooperates with the isolation plate 33 on the side near the switch cabinet side plate 1. A sealing gasket is placed in the groove. The sealing performance of the inspection port 2 is further improved by the groove and the sealing gasket.

[0035] The four corners of the linkage frame 32 are rotatably connected to pulleys 4, which roll against the guide rail 31, allowing the linkage frame 32 to slide quickly.

[0036] Working principle: When using this switch cabinet component, the servo motor 39 drives the worm gear 310 to rotate, causing the worm wheel 38 to mesh and move. At this time, the transmission rod 36 rotates synchronously and drives the gear 37 to rotate. The gear 37 causes the rack 35 to mesh and move, and drives the linkage frame 32 to slide. Simultaneously, the isolation plate 33 slides, realizing the rapid opening and closing of the access port 2. At the same time as opening and closing, the guide wheel 312 slides in the slot of the fine adjustment plate 311. Under the limiting action of the slot, the linkage rod 34 drives the isolation plate 33 to move laterally, so that it can be tightly abutted against the access port 2.
