Description

Technical Field

[0001] This utility model belongs to the field of control cabinet technology, and specifically relates to an easy-to-maintain protective mechanism for control cabinets. Background Technology

[0002] A control cabinet is a complete set of equipment that assembles switching devices, 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 normal operation control, fault protection and parameter monitoring of power systems. In order to protect the inside of the control cabinet, a protective mechanism is usually set at the air inlet of the control cabinet to block dust and other substances. Existing protective mechanisms typically use filters to block dust, lint, and other impurities. However, these filters often suffer from several problems. For example, after prolonged use, dust and lint tend to accumulate on their surface. While cleaning is usually done with a brush, the force of the brush can cause fine dust to penetrate deeper into the filter pores, thus worsening the blockage instead of cleaning the filter. Therefore, we propose a maintenance-friendly protective mechanism for control cabinets to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide an easy-to-maintain protective mechanism for control cabinets. Its advantages are that the protective mechanism is easy to disassemble and assemble, convenient to maintain and clean, and improves the efficiency of the protective mechanism.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1: refer to Figure 1 , Figure 2 and Figure 4 A maintenance-friendly protective mechanism for a control cabinet includes a control cabinet body 1 and a housing 4. A nut 7 is welded to one side of the inner cavity of the housing 4. A locking bolt 5 is threaded into the inner cavity of the nut 7. A bearing body 12 is movably connected to one side of the locking bolt 5. A sliding plate 11 is welded to one side of the bearing body 12. An insert rod 10 is welded to one side of the sliding plate 11. A connecting rod 3 is inserted into one side of the insert rod 10. A connecting block 2 is welded to one end of the connecting rod 3. A filter screen plate 6 is welded to one end of the connecting block 2.

[0023] Furthermore, limiting grooves are provided at both ends of the inner cavity of the housing 4, and both ends of the sliding plate 11 are slidably connected in the inner cavity of the limiting grooves. The limiting grooves improve the sliding stability of the sliding plate 11.

[0024] Furthermore, the surface of the connecting rod 3 is provided with a socket 16, and one end of the plug rod 10 is inserted into the inner cavity of the socket 16. The socket 16 facilitates the insertion of the plug rod 10.

[0025] Furthermore, support columns are welded around the bottom of the control cabinet body 1, and anti-slip pads are adhered to the bottom of the support columns. The support columns facilitate the support of the equipment, while the anti-slip pads effectively prevent the equipment from sliding during use, thus improving the stability of the equipment's operation.

[0026] Furthermore, an air inlet is provided at the bottom right side of the control cabinet body 1, and the surface of the filter screen 6 is attached to the surface of the air inlet. By setting the connection between the air inlet and the filter screen 6, the protection efficiency of the filter screen 6 is improved.

[0027] Example 2: refer to Figure 2 and Figure 3 A maintenance-friendly protective mechanism for a control cabinet includes a telescopic shell 8 welded to both ends of one side of the inner cavity of a housing 4. A damper 13 is bolted to one side of the inner cavity of the telescopic shell 8. A spring 14 is fitted on the surface of the damper 13. A reset plate 15 is bolted to one side of the spring 14. A telescopic rod 9 is bolted to one side of the reset plate 15. One side of the telescopic rod 9 is welded to the surface of a sliding plate 11. Through the damper 13, spring 14, reset plate 15, and telescopic rod 9, the sliding plate 11 is easily driven to reset and move, avoiding jamming of the sliding plate 11 during the reset and moving process, and improving the stability of the reset and moving of the sliding plate 11.

[0028] Furthermore, both ends of the inner cavity of the telescopic shell 8 are provided with sliding grooves, and both ends of the reset plate 15 are slidably connected to the inner cavity of the sliding grooves. Through the sliding grooves, the reset plate 15 can slide in its inner cavity, which improves the stability of the sliding of the reset plate 15.

[0029] Brief description of usage: First, after prolonged use, the surface of the filter screen 6 easily accumulates dust, lint, and other impurities. The user periodically rotates the locking bolt 5 in reverse using a wrench. Since the threads on the surface of the locking bolt 5 and the threads inside the nut 7 are threadedly connected, rotating the locking bolt 5 allows it to move. For example, rotating the locking bolt 5 clockwise moves it inwards, and vice versa. When the locking bolt 5 moves outwards in the reverse direction, it drives the bearing body 12 to move, thus limiting the movement of the sliding plate 11. The pressure is then eliminated, and the damper 13 and spring 14 automatically reset. Through the damper 13 and spring 14, the reset plate 15 can be effectively moved by its own reset elasticity. The reset plate 15 then moves the telescopic rod 9 to reset, which in turn moves the sliding plate 11. The sliding plate 11 then moves the insertion rod 10 to reset. The insertion rod 10 then disengages from the inner cavity of the insertion port 16, thus eliminating the limiting pressure on the insertion port 16. The user can then remove the filter screen 6 for maintenance and cleaning.

[0030] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0031] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
