[0003] Existing factory distribution cabinets are dusty in factories, especially in places outside the distribution room. In order to prevent dust from entering the distribution cabinet and affecting the use of components, dust screens are usually installed at the vents. Dust will accumulate on the dust screens. The more dust accumulates, the more it will affect the heat dissipation inside the distribution cabinet, which may cause the components in the cabinet to burn out, and the motors or other related equipment in the factory to fail to work. Therefore, personnel are required to frequently clean the dust screens on the distribution cabinets to keep them clean, which greatly increases the workload of the staff. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a power distribution cabinet for a factory, which can solve the technical problem of replacing the filter components for heat dissipation and dust prevention of the power distribution cabinet.

[0005] The embodiment of the present application provides a power distribution cabinet for a factory, including a cabinet body, a protection component and a limit component;

[0006] The cabinet body is symmetrically provided with ventilation holes and a receiving cavity on both sides, a loading port is connected to the upper side of the receiving cavity, a discharge port is connected to the lower side of the receiving cavity, and limiting grooves are symmetrically provided on the inner wall of the receiving cavity;

[0007] A plurality of the protective components may be placed in the accommodating chamber, and the protective components include a movable frame and a filter screen, wherein the filter screen is fixedly arranged in the movable frame, and the movable frame is slidably arranged in the accommodating chamber;

[0008] The limiting assembly is arranged in the two side walls of the accommodating cavity.

[0009] Furthermore, the limit assembly includes a card block, a limit block, a pull rod, an installation groove and a return spring, the installation groove is opened in the side wall of the cabinet, the card block is fixedly set on the movable frame, the limit block is slidably set in the installation groove, one end of the pull rod is connected to the limit block, and the other end of the pull rod passes through the side wall of the cabinet, the return spring is sleeved outside the pull rod, and one end of the return spring abuts against the limit block, and the other end of the return spring abuts against the inner wall of the installation groove.

[0029] The embodiment of the present application discloses a power distribution cabinet for a factory.

[0030] Reference Figure 1-4 , a power distribution cabinet for a factory, comprising a cabinet body 1, a protection component 2 and a limit component 3;

[0031] The cabinet 1 is symmetrically provided with ventilation holes 11 and accommodating chambers 12 on both sides. The accommodating chamber 12 is connected to the ventilation holes 11. A loading port 13 is provided above the accommodating chamber 12. A discharge port 14 is provided below the accommodating chamber 12. Limiting grooves 15 are symmetrically provided on the inner wall of the accommodating chamber 12.

[0032] A plurality of protection components 2 may be placed in the accommodating chamber 12. The protection components 2 include a moving frame 21 and a filter 22. The filter 22 is fixedly disposed in the moving frame 21, and the moving frame 21 is slidably disposed in the accommodating chamber 12.

[0033] The limiting assembly 3 is arranged in the two side walls of the accommodating cavity 12;

[0034] When in use, multiple protective components 2 can be put into the material port 13, and the protective component 2 put in earliest can be limited and abutted by the setting of the limiting component 3, so that the protective component 2 is located at the vent 11. When the dust accumulated in the filter screen 22 at the vent 11 reaches a certain weight, the movable frame 21 at the vent 11 will cause the limiting component 3 to shrink due to gravity, so that the movable frame 21 at the vent 11 can automatically fall off without manual disassembly. After the movable frame 21 at the vent 11 falls off, the movable frame 21 located above the accommodating cavity 12 will fall to the vent 11 at the same time and abut against the limiting component 3. There is no need for manual replacement, which extends the maintenance cycle of the heat dissipation in the cabinet and saves time and effort.

[0035] Reference Figure 2 , Figure 4The limiting assembly 3 includes a card block 31, a limiting block 32, a pull rod 33, an installation groove 34 and a reset spring 35. The installation groove 34 is opened in the side wall of the cabinet 1. The card block 31 is fixedly set on the moving frame 21, and the limiting block 32 is slidably set in the installation groove 34. One end of the pull rod 33 is connected to the limiting block 32, and the other end of the pull rod 33 passes through the side wall of the cabinet 1. The reset spring 35 is sleeved outside the pull rod 33, and one end of the reset spring 35 abuts against the limiting block 32, and the other end of the reset spring 35 abuts against the inner wall of the installation groove 34. When in use, when the moving frame 21 falls to the vent 11, the card block 31 abuts against the limiting block 32, so that the moving frame 21 and the filter screen 22 is located at the vent 11 for filtering and blocking. When the dust accumulated in the filter screen 22 at the vent 11 reaches a certain weight, the block 31 descends and compresses the limit block 32, causing the limit block 32 to shrink into the installation slot 34. The reset spring 35 is compressed. After the dusty moving frame 21 falls, the limit block 32 is reset, and the unused moving frame 21 and filter screen 22 above fall onto the limit block 32, effectively limiting and positioning the protective component 2. The limit block 32 is driven into the installation slot 34 by pulling the pull rod 33 to prevent the reset spring 35 from getting stuck, thereby ensuring that the protective component 2 can be manually replaced.

[0036] Reference Figure 2 More specifically, a limiting plate 321 is provided at one end of the limit block 32 connected to the pull rod 33, which can effectively limit the extension of the limit block 32 to avoid excessive protrusion during resetting and causing abutment with the moving frame 21.

[0037] Reference Figure 3 The loading port 13 is also provided with a guide groove 16 for inserting the card block 31 , the guide groove 16 is connected with the limit groove 15 , and the guide groove 16 is arranged to be inclined downward from the outside to the inside, so as to facilitate the quick alignment and insertion of the movable frame 21 .

[0038] Reference Figure 4 The moving frame 21 is also provided with a taking groove 221 for inserting fingers for taking, so as to facilitate taking of the moving frame 21.

[0039] Reference Figure 3 More specifically, the bottom of the discharge port 14 is tilted to facilitate automatic discharge of the filter components that have been filtered for a long time without accumulating and getting stuck at the discharge port 14 .

[0040] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
