[0030] 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.

[0031] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a communication base station power cabinet, including a chassis 1, a cabinet door 2 is rotatably connected to the outside of the chassis 1, a filter screen 3 is fixedly connected to one side of the cabinet door 2, a mounting groove 24 is provided inside the cabinet door 2, a motor 9 is slidably connected inside the mounting groove 24, a gear 10 is fixedly connected to the output end of the motor 9, a cleaning plate 12 is slidably connected to the inside of the cabinet door 2, a limiting groove 19 is provided inside the cleaning plate 12, a buffer spring 20 is fixedly connected inside the limiting groove 19, a connecting plate 21 is fixedly connected to one end of the buffer spring 20, a limiting column 13 is slidably connected to one side of the cleaning plate 12, a rack 11 is fixedly connected inside the mounting groove 24, a heat sink 6 is fixedly connected to the other side of the cabinet door 2, and a disassembly component is installed inside the chassis 1.

[0032] Specifically, the chassis 1 is the main structure of the power cabinet, which is used to accommodate and protect the internal power supply machine 5. The cabinet door 2 is connected to the chassis 1 by a rotating connection, which is convenient to open and close for maintenance. The filter 3 is installed on one side of the cabinet door 2. Its main function is to prevent dust particles in the external airflow from entering the interior of the chassis 1. The motor 9 is used as a driving source and is connected to the gear 10 through its output end to provide power for the cleaning process. When the motor 9 is started, the gear 10 will rotate outside the rack 11, thereby realizing the linear motion of the cleaning plate 12. When the cleaning plate 12 moves, the buffer spring 20 will release the tension, and then help the connecting plate 21 and the brush 22 to better fit the surface of the filter 3, so as to effectively clean the dust. The limit column 13 is slidably connected to one side of the cleaning plate 12. Its function is to ensure that the cleaning plate 12 remains stable during the movement and prevent it from excessive movement. The heat sink 6 is fixed on the other side of the cabinet door 2. Its function is to dissipate the heat generated by the power supply machine 5 equipment to ensure the stability of the internal temperature of the power cabinet.

[0033] Reference Figure 2 and Figure 4 The disassembly assembly includes a support frame 7, two ends of the two support frames 7 are fixedly connected to the inside of the chassis 1, two connection grooves 18 are opened inside the two support frames 7, the inside of the two connection grooves 18 is slidably connected with a pull rod 14, the outside of the pull rod 14 is sleeved with a compression spring 15, one end of the compression spring 15 is fixedly connected to a moving plate 16, two power supplies 5 are arranged inside the chassis 1, the outside of the two power supplies 5 is fixedly connected to two connection plates 8, and the inside of the two connection plates 8 is opened with grooves 17.

[0034] Specifically, the two support frames 7 are respectively installed at the two ends inside the chassis 1, and are used to support and fix the power supply unit 5. They are fixed to the outside of the power supply unit 5. A groove 17 is provided inside the connecting plate 8, which is used to be inserted with one end of the pull rod 14 to fix the power supply unit 5. The pull rod 14 is slidably connected in the connecting groove 18, and the disassembly and assembly of the power supply unit 5 is controlled by pulling or pushing. The compression spring 15 is sleeved on the outside of the pull rod 14. When the pull rod 14 is pulled, the compression spring 15 contracts the tension. When the pull rod 14 is released, the compression spring 15 releases the tension and pushes the pull rod 14 to reset. The movable plate 16 is fixedly connected to one end of the compression spring 15, and moves with the movement of the pull rod 14, thereby controlling the contraction and release of the compression spring 15.

[0035] Reference Figure 3 and Figure 5The corresponding position of the outside of the gear 10 is meshed and connected with the outside of the rack 11, and a cleaning plate 12 is rotatably connected to one side of the gear 10. A collecting hole 25 is opened at the bottom of the cabinet door 2, and a dust box 4 is provided at the bottom of the cabinet door 2. The two ends of the limit column 13 are fixedly connected to the inside of the mounting groove 24, and the outside of the connecting plate 21 is slidably connected to the inside of the limit groove 19. A plurality of brushes 22 are fixedly connected to the outside of the connecting plate 21, and a handle 23 is fixedly connected to the cabinet door 2.

[0036] Specifically, the outside of the gear 10 is meshed with the outside of the rack 11, which means that when the gear 10 rotates, it drives the rack 11 to move linearly, and the rotation of the gear 10 drives the cleaning plate 12 to move. When the cleaning plate 12 sweeps the dust, the dust falls into the dust box 4 through the collection hole 25, thereby preventing it from being redistributed into the interior of the device or the surrounding environment. The limiting column 13 ensures that the connecting plate 21 remains on a predetermined path when moving, preventing it from deviating or moving excessively. When the connecting plate 21 slides in the limiting groove 19, the brush 22 may contact the surface of the filter 3, thereby effectively removing the accumulated dust. The handle 23 provides a convenient way to open and close the cabinet door 2. The user can easily open the cabinet door 2 by holding and pulling the handle 23, thereby facilitating the inspection and maintenance of the internal equipment.

[0037] Referring to 4 , one end of the pull rod 14 is inserted into the groove 17 , and the other end of the pull rod 14 extends to the outside of the support frame 7 and is provided with a handle. The outside of the movable plate 16 is slidably connected to the inside of the connecting groove 18 .

[0038] Specifically, the pull rod 14 moves linearly in the groove 17, so that the groove 17 provides positioning and guiding functions for the pull rod 14, and the other end of the pull rod 14 extends to the outside of the support frame 7 and is provided with a handle. The handle is usually a component that is convenient for users to hold and operate, and the connecting groove 18 provides a guiding function for the moving plate 16 through the movement of the moving plate 16.

[0039] Working principle: when the power supply 5 is running inside the chassis 1, the heat generated is discharged to the outside through the heat sink 6, so that the heat will not accumulate inside the chassis 1, and at the same time, the external airflow will also circulate the heat sink 6 through the filter 3, wherein the dust particles mixed in the external air will be blocked by the filter 3, however, by starting the motor 9, the gear 10 rotates outside the rack 11, so that the gear 10 drives the cleaning plate 12 to move, and at the same time, the buffer spring 20 inside the cleaning plate 12 releases the tension, and then the connecting plate 21 drives the brush 22 to clean the dust outside the filter 3, and the cleaned dust will enter the inside of the dust box 4 from the collecting hole 25, so that the dust cannot accumulate on the filter 3;

[0040] Secondly, when the staff needs to inspect the power supply 5, they can pull the pull rod 14 on the outside of the support frames 7 on both sides, so that the compression spring 15 contracts the tension inside the connecting groove 18, thereby moving the movable plate 16 and making one end of the pull rod 14 disengage from the inside of the groove 17, so that it is convenient for the staff to move the power supply 5 out of the inside of the chassis 1 for inspection. At the same time, when the power supply 5 is fixed inside the chassis 1, by placing the power supply 5 inside the support frame 7, the pull rod 14 is pushed, so that the compression spring 15 releases the tension, thereby moving the movable plate 16, and then driving one end of the pull rod 14 to be inserted into the inside of the groove 17, so that the power supply 5 is not easy to slip inside the chassis 1, thereby ensuring stable operation.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
