Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically a flip-up internal component mounting rack structure for an electrical cabinet that is easy to maintain. Background Technology

[0002] Components generate a lot of heat when they are working, and they are also quite sensitive to high temperatures. If the temperature inside our distribution cabinet is too high for a long time, it will seriously affect the operational stability and lifespan of our electrical equipment. Furthermore, external dust can easily enter the electrical cabinet through gaps, causing a decrease in the heat dissipation efficiency of the internal components and reducing their lifespan.

[0003] A search of Chinese patent CN214478661U reveals an electrical cabinet with a sliding, flip-type component mounting plate. Through the arrangement of a rotating shaft and a rotating frame, this cabinet effectively prevents dust from entering the cabinet, thus protecting the electrical components. The design utilizes a rotating shaft, a driving bevel gear, a driven bevel gear, a rotating shaft, a rotating frame, a belt, and a servo motor. During use, electrical components can be initially placed on the side of the rotating frame, with one side closed to electrical components and the other two sides suitable for motor components. When replacement or maintenance is required, the servo motor is activated. The output of the servo motor drives the rotating shaft via the belt, which in turn drives the driving bevel gear, which in turn drives the driven bevel gear. The driven bevel gear then rotates the rotating shaft inside the cabinet, causing the rotating frame to rotate, thereby allowing the electrical components to be rotated out for easy maintenance. This design effectively prevents dust accumulation and facilitates maintenance.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The internal components of the electrical cabinet are in fixed positions and cannot be moved to the outer position for maintenance when the electrical cabinet door is open. In addition, the fan brings air into the cabinet for heat dissipation, and the exposed components are prone to dust accumulation when in direct contact with the air, which reduces the maintenance efficiency of the electrical cabinet. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical cabinet with a flip-up internal component mounting rack structure that is easy to maintain, so as to solve the problems mentioned in the background art.

[0006] The technical solution of this utility model is: a reversible internal component mounting rack structure for an electrical cabinet that is easy to maintain, including a cabinet, wherein a slide rail is provided on the bottom inner wall of the cabinet, and further comprising;

[0007] A flipping mechanism is disposed inside the housing;

[0008] The flipping mechanism includes a mounting frame slidably connected to the inner wall of the slide rail. A motor is mounted on one side of the bottom inner wall of the mounting frame. One end of the motor output shaft is connected to a rotating rod via a coupling. Several bevel gears are fixedly connected to the outer wall of the rotating rod.

One end of the piston rod of the telescopic rod is fixedly connected to the inner wall of the housing. A return spring is sleeved on the outer wall of the telescopic rod.

[0009] Preferably, the two ends of the reset spring are fixedly connected to the inner wall of the housing and the outer wall of the mounting frame, respectively, and the outer wall of the housing is connected to an electrical cabinet door via a hinge.

[0010] Preferably, the movable rod, bevel gear one, and bevel gear two are arranged in a linear array, and bevel gear one and bevel gear two mesh.

[0011] Preferably, the arc-shaped plate is abutted against the outer wall of the extrusion plate, and the bottom outer wall of the mounting frame is provided with an arc-shaped hole.

[0013] This utility model provides an improved, easily maintainable, flip-type internal component mounting bracket structure for electrical cabinets, which has the following improvements and advantages compared to the prior art:

[0014] Firstly, this utility model features a housing, a diversion plate, a motor, a mounting frame, an electrical cabinet component mounting plate, a pressing plate, and an arc-shaped plate. The mounting frame returns to the housing under the action of a return spring and a telescopic rod. The mounting frame is separated from the filter screen. The fan blows air through the heat dissipation holes on the mounting frame and the movable plate for heat dissipation. The air does not directly contact the internal components to prevent dust adhesion. When maintenance is required, the motor drives bevel gear one and bevel gear two to rotate in opposite directions. The movable plate rotates in opposite directions to expose the electrical cabinet component mounting plate and internal components. The pressing plate presses the arc-shaped plate, causing the mounting frame to move outward. The internal components move with the mounting frame to move out of the housing for easy maintenance. The fan carries air into the housing for heat dissipation. At this time, the internal components are protected between the mounting frame and the housing, preventing direct contact with the air and dust blockage of the components. This improves the maintenance efficiency of the electrical cabinet's flip-type internal component mounting frame structure.

[0015] Secondly, this utility model, by incorporating a fan, a diverter plate, a filter screen, and a mounting frame, ensures that the mounting frame passes over the filter screen as it moves outward before and after each maintenance. The impurities filtered by the filter screen are cleaned by the mounting frame, guaranteeing unobstructed airflow and improving the practicality of the flip-type internal component mounting rack structure of the electrical cabinet.

[0025] like Figures 1-4 As shown, an electrical cabinet with a flip-up internal component mounting rack structure for easy maintenance includes a cabinet 1, with a slide rail provided on the bottom inner wall of the cabinet 1, and also includes;

[0026] A flipping mechanism is located inside the housing 1;

[0027] The flipping mechanism includes a mounting frame 4 slidably connected to the inner wall of the slide rail. A motor 5 is mounted on one side of the bottom inner wall of the mounting frame 4. One end of the output shaft of the motor 5 is connected to a rotating rod 7 via a coupling. Several bevel gears 6 are fixedly connected to the outer wall of the rotating rod 7. Several mounting holes are opened on one side of the outer wall of the mounting frame 4. A movable rod 10 is rotatably mounted on the inner wall of the mounting holes. A movable plate 11 is fixedly connected to the outer wall of the movable rod 10. Several electrical cabinet component mounting plates 12 are fixedly connected to one side of the outer wall of the movable plate 11. A bevel gear 9 is fixedly connected to the bottom outer wall of the movable rod 10. Several extrusion plates 13 are fixedly connected to the bottom inner wall of the housing 1. An arc-shaped plate 8 is fixedly connected to the bottom outer wall of the movable rod 10. Telescopic rods 15 are fixedly connected to one side of the top and bottom outer walls of the mounting frame 4. One end of the piston rod of the telescopic rod 15 is fixedly connected to the inner wall of the housing 1. A return spring 14 is sleeved on the outer wall of the telescopic rod 15.

[0028] Furthermore, the two ends of the return spring 14 are fixedly connected to the inner wall of the housing 1 and the outer wall of the mounting frame 4, respectively. The outer wall of the housing 1 is connected to the electrical cabinet door by a hinge. The movable rod 10, bevel gear 6 and bevel gear 9 are arranged in a linear array, and bevel gear 6 and bevel gear 9 mesh.

[0029] Furthermore, the arc-shaped plate 8 is connected to the outer wall of the extrusion plate 13. The bottom outer wall of the mounting frame 4 has an arc-shaped hole. The size of the arc-shaped plate 8 matches the size of the arc-shaped hole. The size of the movable plate 11 matches the size of the mounting hole. The outer wall of the movable plate 11 has heat dissipation holes. The outer walls of both sides of the housing 1 have through holes. The inner wall of the through holes is fixedly connected to a filter screen 16. The outer wall of one side of the housing 1 is fixedly connected to a diverter plate 2. A fan 3 is installed on the outer wall of one side of the diverter plate 2.

The impurities filtered by the filter screen 16 are cleaned by the mounting frame 4 to ensure smooth airflow.

[0030] Working principle: The electrical cabinet features a flip-up internal component mounting bracket structure for easy maintenance. Internal components are mounted on the component mounting plate 12 of the movable plate 11. When the electrical cabinet door of the housing 1 is closed, the motor 5 starts, driving the movable plate 11 to rotate via the rotating rod 7 and meshing bevel gears 6 and 9. The movable plate 11 rotates the component mounting plate 12 towards the mounting frame 4. The rotation of the movable rod 10 also rotates the arc-shaped plate 8, causing it to separate from the pressing plate 13. The mounting frame 4 returns to the housing 1 under the action of the return spring 14 and the telescopic rod 15, thus separating the mounting frame 4 from the filter screen 16. The fan 3 blows air through the heat dissipation holes on the mounting frame 4 and the movable plate 11 for heat dissipation. The air does not directly contact the internal components to prevent dust from adhering. When maintenance is required, the motor 5 drives the bevel gear 6 and bevel gear 9 to rotate in opposite directions. The movable plate 11 rotates in opposite directions to expose the electrical cabinet component mounting plate 12 and internal components. The pressing plate 13 presses the arc plate 8, causing the mounting frame 4 to move outward. The internal components move with the mounting frame 4 to move outward from the cabinet 1 for easy maintenance. Before and after each maintenance, the mounting frame 4 passes the filter screen 16 when it moves outward. The impurities filtered by the filter screen 16 are cleaned by the mounting frame 4 to ensure smooth airflow.
