[0002] A control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements. It is mainly used for the automatic control, monitoring and protection of power systems, industrial equipment and building facilities to ensure the safe and stable operation of the system.

[0003] A patent search revealed a document titled "Heat Dissipation Air Duct Structure for Control Cabinets and Control Cabinets," with publication number "CN219372933U." This document describes a device that uses an airflow drive to exchange air between the control cabinet and the outside environment, thereby dissipating heat from the electronic components inside the cabinet. Traditional airflow drive devices typically include filters to remove dust and prevent it from entering the control cabinet. However, these devices cannot remove dust adhering to the filter surface, leading to filter blockage and hindering airflow, thus affecting the heat dissipation effect inside the control cabinet. Therefore, this invention designs a control cabinet air duct structure to solve the aforementioned problems. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] A preferred embodiment of the control cabinet air duct structure provided by this utility model is, for example... Figures 1 to 4The diagram shows a control cabinet air duct structure, comprising a cabinet body 1, a mounting sleeve 2 fixedly disposed in the middle of the interior of the cabinet body 1; a clearance hole 3 integrally disposed in the lower end of the interior of the mounting sleeve 2, a partition 4 fixedly disposed on the outer wall of the mounting sleeve 2 and connected to the cabinet body 1; a threaded hole 5 integrally disposed in the bottom end of the interior of the cabinet body 1, a mounting hole 6 integrally disposed in the interior of the cabinet body 1 and a filter screen 7 fixedly disposed inside the mounting hole 6; a sealing plate 8 disposed on the top of the cabinet body 1, and a mounting tube 9 fixedly disposed inside the sealing plate 8, the mounting tube 9 penetrating the mounting sleeve 2; and a drive assembly 10 assembled outside the sealing plate 8, the drive assembly 10 removing dust adhering to the surface of the filter screen 7, the drive assembly 10 including a motor 1001 fixedly disposed on the top of the sealing plate 8, and a scraper 1002 fixedly sleeved on the outside of the output end of the motor 1001, the partition 4, the mounting hole 6 and the clearance hole 3 being several pieces, the partition 4 and the mounting hole 6 being offset from each other, and the inner wall of the scraper 1002 being in contact with the outer wall of the filter screen 7.

[0028] It should be noted that the existing control cabinet air duct structure still has certain shortcomings in actual use. It cannot remove the dust adhering to the surface of the filter screen, which affects the heat dissipation effect inside the cabinet.

[0029] In this embodiment, the partition 4 first divides the interior of the cabinet 1 into several storage compartments. The operator first places different types of electronic components into the cabinet 1 according to their categories, then uses bolts to connect the electronic components to the threaded holes 5, thus securing the electronic components to the cabinet 1. The operator then places the sealing plate 8 on top of the cabinet 1, so that the scraper 1002 and the filter screen 7 are in contact. At this time, the gas inside the cabinet 1 communicates with the outside gas through the mounting holes 6, clearance holes 3, and mounting pipes 9, thereby achieving the exchange of gas between the inside and outside of the cabinet 1, and thus dissipating heat from the electronic components inside the cabinet 1. Simultaneously, external dust adheres to the filter screen 7. The operator then turns on the motor 1001, which drives the scraper 1002 to rotate. The rotating scraper 1002 removes the dust adhering to the surface of the filter screen 7, ensuring smooth gas exchange between the inside and outside of the cabinet 1.

[0030] In a further preferred embodiment of this utility model, a protective sleeve 11 is fixedly fitted on the outside of the cabinet 1. Several clearance holes 12 are integrally provided inside the protective sleeve 11, and the clearance holes 12 correspond one-to-one with the mounting holes 6. A controller 13 is fixedly provided on the outer wall of the protective sleeve 11. The controller 13 is connected to the motor 1001 through a wire. The motor 1001 is a geared motor. A discharge hole 14 is integrally provided at the bottom inside the protective sleeve 11. An exhaust assembly is provided on the outside of the sealing plate 8. The exhaust assembly can improve the flow speed of the gas inside the cabinet 1. The exhaust assembly includes an air pump 15 fixed on the top of the sealing plate 8 and a connector 16 fixed on the bottom of the air pump 15. The air pump 15 is connected to the controller 13 through a wire. The air pump 15 and the motor 1001 are offset from each other. The connector 16 is embedded inside the mounting tube 9.

[0031] In this embodiment, the protective sleeve 11 prevents the operator's hands from coming into contact with the rotating scraper 1002. The clearance hole 12 provides working space for the filter screen 7. The dust scraped off the surface of the filter screen 7 is discharged to the outside through the discharge hole 14, preventing the scraped dust from accumulating inside the protective sleeve 11. In addition, the operator can turn on the air pump 15. The air pump 15 quickly discharges the gas inside the cabinet 1 to the outside through the clearance hole 3, the mounting pipe 9 and the connector 16, thereby allowing the outside gas to quickly pass through the filter screen 7 and enter the cabinet 1, improving the efficiency of gas flow inside the cabinet 1, that is, improving the heat dissipation effect inside the cabinet 1.

[0032] Example 2

[0033] Based on Embodiment 1, a preferred embodiment of the control cabinet air duct structure provided by this utility model is as follows: Figures 1 to 4 As shown: Limiting holes 17 are integrally provided on the left and right sides inside the cabinet 1. A detachable limiting pin 18 is provided inside the limiting hole 17. The limiting pin 18 is fixedly connected to the sealing plate 8. A connecting hole 19 is integrally provided inside the limiting pin 18. Insertion holes 20 are integrally provided on the left and right sides at the upper end of the cabinet 1. The insertion holes 20 and the connecting holes 19 correspond to each other. Mounting plates 21 are fixedly provided on the left and right sides at the bottom of the sealing plate 8. A worm gear sleeve 22 is rotated inside the mounting plate 21. A top pin 23 is threaded inside the worm gear sleeve 22. The top pin 23 is slidably connected to the sealing plate 8. A worm 24 is rotatably passed through the left and right sides at the top of the sealing plate 8. The worm 24 meshes with the gear teeth of the worm gear sleeve 22.

[0034] In this embodiment, when the sealing plate 8 is placed on top of the cabinet 1, the limiting pin 18 is first inserted into the limiting hole 17, and then the worm 24 is rotated. The worm 24 controls the worm gear sleeve 22 to rotate. Through the threaded transmission design of the worm gear sleeve 22 and the top pin 23, the top pin 23 passes through the insertion hole 20 and is inserted into the connecting hole 19, thereby locking the state of the sealing plate 8 and the cabinet 1 after combination.

[0035] In summary, this application effectively removes dust adhering to the filter surface, ensuring stable heat dissipation within the cabinet. The exhaust function allows for rapid exchange of air between the cabinet interior and the outside environment, enhancing internal heat dissipation. The detachable design improves the ease of combining or separating the sealing plate from the cabinet, while the locking function enhances the stability of the combined sealing plate and cabinet, preventing separation due to vibration during operation of the air pump and motor.
