Detailed Implementation

[0019] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and by way of embodiments. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0020] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously. The term " / and" in this article describes another type of relationship between related objects, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the related objects before and after it are in an "or" relationship.

[0021] according to Figures 1-17 As shown, a self-cleaning and moisture-proof self-resetting intermediate frequency power supply cabinet includes a moisture-proof self-resetting component and a self-cleaning component. The moisture-proof self-resetting component is disposed on the power supply cabinet 1, and the self-cleaning component is disposed on the moisture-proof self-resetting component. The moisture-proof self-resetting component includes a protective shell 2, a ventilator 3, a first moisture-proof self-resetting component, and a second moisture-proof self-resetting component. The protective shell 2 and the ventilator 3 are both disposed on the power supply cabinet 1, and the first moisture-proof self-resetting component and the second moisture-proof self-resetting component are both disposed on the protective shell 2.

[0022] The protective shell 2 is rectangular tubular, with its left and right sides wider than the left and right sides of the power cabinet 1, and its front and rear ends wider than the front and rear ends of the power cabinet 1. Mounting grooves, rectangular in shape, are formed on the front and rear ends of the protective shell 2, with a depth greater than the length of the power cabinet 1. The protective shell 2 is attached to the power cabinet 1 from top to bottom through the mounting grooves, forming a relay cavity between the top surface of the protective shell 2 and the top surface of the power cabinet 1. The two side walls of the protective shell 2 correspond to the two side surfaces of the power cabinet 1, forming drying and restoring cavities. The first moisture-proof self-restoring component and the second moisture-proof self-restoring component are installed in the two drying and restoring cavities one after the other. The bottom end of the ventilator 3 is disposed on the top surface of the power cabinet 1, and the ventilator 3 is located within the relay cavity.

[0023] Each of the drying and reduction chambers is equipped with a partition plate 4. The partition plate 4 is sealed to the side wall of the power cabinet 1 and the side wall of the protective shell 2 along its vertical sides, and sealed to the top and bottom surfaces of the protective shell 2 along its vertical ends, thus dividing the drying and reduction chamber into a drying chamber 5 and a reduction chamber 6. Furthermore, the top of the drying chamber 5 communicates with the relay chamber, and the bottom of the drying chamber 5 protrudes downwards from the bottom of the power cabinet 1, so that the bottom of the drying chamber 5 communicates with the bottom of the power cabinet 1. A first sealing plate is provided between the top of the reduction chamber 6 and the relay chamber for sealing, and a second sealing plate is provided between the bottom of the reduction chamber 6 and the relay chamber for sealing. This makes the reduction chamber 6 an independent sealed chamber.

[0024] Furthermore, a ventilation inlet 7 is provided on the side wall of the protective shell 2 of the drying chamber 5. A ventilation filter is detachably installed on the ventilation inlet 7. External air enters the drying chamber 5 through the ventilation filter, and then is sent into the power cabinet 1 through the relay chamber by the fan 3 to dissipate heat and cool the electrical components. Finally, it is discharged from the ventilation outlet 35 at the bottom of the power cabinet 1. The discharged air, having absorbed heat, dehumidifies and dries the bottom of the power cabinet 1, preventing corrosion of the bottom of the power cabinet 1. Particulate matter in the external air is filtered out by the ventilation filter.

[0025] The first moisture-proof self-restorer includes a drying component and a restoration component, both of which are disposed within the protective shell 2. The drying component is located within the drying chamber 5, and the restoration component is located within the restoration chamber 6. The drying component includes a drying plate 10 and a drying ventilation control component, both of which are disposed within the drying chamber 5.

[0026] The drying plate 10 is installed on the first mounting base inside the drying chamber 5 after the ventilation filter is removed, and the drying plate 10 maintains a predetermined distance from both one side of the power cabinet 1 and the ventilation filter. Further, the drying plate 10 is generally rectangular, with its top edge sealed to the top plate 8 of the first mounting base, its bottom edge sealed to the bottom plate 9 of the first mounting base, and its two sides sealed to the front and rear sides of the protective shell 2, respectively. The top plate 8 is rectangular, with one side horizontally fixed to one side wall of the protective shell 2 above the drying chamber 5, and one side horizontally fixed to one side wall of the bottom end of the power cabinet 1 below the drying chamber 5. Alternatively, the drying plate 10 can be constructed by splicing together multiple rectangular drying plates 10.

[0027] The drying and ventilation control component includes an opening and closing plate 11, an opening and closing seat 12, a first magnetic coil, and an opening and closing transmission shaft 13. The opening and closing plate 11 is rectangular and is slidably disposed on the top surface of the top plate 8 of the first mounting base. The opening and closing seat 12 is tubular and is horizontally disposed on the inner wall of the protective shell 2 of the drying chamber 5 at one end. The first magnetic coil is fixedly embedded in the spiral groove on the inner wall of the opening and closing seat 12. One end of the opening and closing transmission shaft 13 passes through the opening and closing seat 12 and is connected to the top surface of the opening and closing plate 11. When the drying plate 10 of the first moisture-proof self-restored component needs to be heated and restored, the drying ventilation control component needs to be turned off first (at this time, the drying ventilation control component of the second moisture-proof self-restored component is turned on to enable the second moisture-proof self-restored component to perform ventilation and drying). That is, when DC current is passed into the first magnetic coil to generate a magnetic field, the opening and closing transmission shaft 13 will be pushed to move to the left. Then, the opening and closing transmission shaft 13 will drive the opening and closing plate 11 to slide to the left to seal and separate the drying chamber 5 and the relay chamber.

[0028] The restoration component includes a heating restoration component and a flow guiding control opening and closing component, both of which are mounted on the protective shell 2. The heating restoration component includes a heating plate and a heating restoration take-up and take-down component, both of which are mounted on the protective shell 2. The heating plate includes a heating support base 14 and an electric heating mesh 15. The heating support base 14 is slidably disposed on the partition plate 4, and the electric heating mesh 15 is disposed on the heating support base 14. When current is applied to the electric heating mesh 15 for heating, the moisture-absorbing drying plate 10 is heated and restored through thermal radiation and thermal convection, facilitating reuse.

[0029] The heating support base 14 is generally rectangular plate in shape. Multiple heating through holes are evenly distributed on the heating support base 14. One end of the heating support base 14 slides through the reduction through hole on the partition plate 4 and extends into the drying chamber 5. A first sealing baffle 16 is provided on one side of the heating support base 14, and a second sealing baffle 17 is provided on the other side of the heating support plate.

[0030] After the heating support 14 is fully slid into the reduction chamber 6, the first sealing baffle 16 abuts and seals one port of the reduction through hole to prevent air from the drying chamber 5 from entering the reduction chamber 6. The reduction through hole is elongated. After the heating support 14 is fully slid into the drying chamber 5, the second sealing baffle 17 abuts and seals the other port of the reduction through hole to prevent air from the drying chamber 5 from entering the reduction chamber 6.

[0031] The heating and releasing mechanism includes a releasing rod 18, a heating transmission seat 19, a second magnetic coil, and a heating transmission rod 20. One end of the releasing rod 18 is fixedly mounted on the second sealing baffle 17, and the other end of the releasing rod 18 passes through a heating and releasing through hole on the bottom surface of the protective shell 2. The heating and releasing through hole is elongated. The heating transmission seat 19 is a thick-walled tube and is fixedly mounted on the bottom surface of the protective shell 2. The second magnetic coil is fixedly embedded in a spiral groove on the inner wall of the heating transmission seat 19 tube. One end of the heating transmission rod 20 slides through the heating transmission seat 19 tube, and the other end of the heating transmission rod 20 is fixedly connected to the other end of the releasing rod 18.

[0032] When a positive direct current is applied to the second magnetic coil to generate a magnetic field, the heating transmission rod 20 will slide to the left, thereby pulling the heating plate into the drying chamber 5 to heat and reduce the drying plate 10. When the drying plate 10 is needed to dry the air supplied to the power cabinet 1, the heating plate can be fully pulled out from the drying chamber 5 into the reduction chamber 6.

[0033] The airflow control opening and closing device includes an inlet airflow guiding opening and closing device, a convection airflow guiding device, and a bottom airflow guiding opening and closing device. The inlet airflow guiding opening and closing device is mounted on the protective shell 2, and the convection airflow guiding device and the bottom airflow guiding opening and closing device are mounted on the power supply cabinet 1. The inlet airflow guiding opening and closing device includes an inlet opening and closing plate 21, an opening and closing rod 22, an opening and closing transmission seat 23, a third magnetic coil, and an opening and closing transmission rod 24. The inlet opening and closing plate 21 is slidably mounted on the partition plate 4, the opening and closing transmission seat 23 is mounted on the protective shell 2, and the third magnetic coil and the opening and closing transmission rod 24 are both mounted on the opening and closing transmission seat 23.

[0034] The air inlet opening / closing plate 21 is rectangular. One end of the air inlet opening / closing plate 21 extends horizontally through the opening / closing through hole on the partition plate 4 into the drying chamber 5, and the other end of the air inlet opening / closing plate 21 is located in the reduction chamber 6. The air inlet opening / closing plate 21 slides and seals within the opening / closing through hole to prevent air from the drying chamber 5 from entering the reduction chamber 6 through the opening / closing through hole. It should be noted that a first sealing groove 25 is provided on the top plate 8. The first sealing groove 25 is located directly above the ventilation inlet 7 and is aligned and connected to the top of the opening / closing through hole. A second sealing groove 26 is provided directly below the first sealing groove 25 and is aligned and connected to the bottom of the opening / closing through hole. The air inlet opening and closing plate 21 continuously slides into the drying chamber 5 through the first sealing groove 25 and the second sealing groove 26, and the air inlet opening and closing plate 21 and the first sealing groove 25 and the second sealing groove 26 slide and seal to separate the ventilation inlet 7 from the drying chamber 5, thereby controlling the hot air in the drying chamber 5 to be blown out from the ventilation inlet 7.

[0035] One end of the opening / closing rod 22 is fixedly mounted on the other end of the air inlet opening / closing plate 21, and the other end of the opening / closing rod 22 passes through the opening / closing through hole on the bottom surface of the protective shell 2. The opening / closing transmission seat 23 is a thick-walled tubular shape and is fixedly mounted on the protective shell 2. The third magnetic coil is fixedly embedded in the spiral groove inside the tube of the opening / closing transmission seat 23. One end of the opening / closing transmission rod 24 slides through the opening / closing transmission seat 23, and the other end of the opening / closing transmission rod 24 is horizontally connected to the other end of the opening / closing rod 22. The opening and closing of the air inlet opening / closing plate 21 is controlled by passing a direct current through the third magnetic coil.

[0036] The convection air intake component includes a convection air intake duct 27 and a solenoid valve. One end of the convection air intake duct 27 is disposed on one side wall of the power cabinet 1, and the solenoid valve is disposed on one end of the convection air intake duct 27 to control the air entering the drying chamber 5 from the power cabinet 1. Further, the other end of the convection air intake duct 27 is closed. After the solenoid valve is opened, air enters the drying chamber 5 through an air intake hole on the side wall of the other end of the convection air intake duct 27. Alternatively, three sets of the convection air intake component are provided, and the three sets are evenly distributed vertically. The air entering the drying chamber 5 through the air intake hole carries the heat generated by the heating plate to the drying plate 10 through the heating hole, improving the heat convection efficiency from the heating plate to the drying plate 10.

[0037] The bottom flow guide opening and closing component includes a bottom opening and closing plate 28. The top edge of the bottom opening and closing plate 28 is hinged to the bottom corner of one side of the power cabinet 1. The bottom opening and closing plate 28 is sealed to the top port of the protective shell 2 by gravity.

[0038] It should be noted that when the first moisture-proof self-resetting component needs to be self-heated for restoration (at which time the first moisture-proof self-resetting component is activated for ventilation and drying): the drying ventilation control component is closed to seal and separate the relay chamber and the drying chamber 5; the solenoid valve is opened to allow some air from the power cabinet 1 to flow into the drying chamber 5; the heating restoration component is activated to pull the heating plate into the drying chamber 5 to heat and restore the drying plate 10. The heating plate heats and restores the drying plate 10 through thermal radiation and thermal convection of the air supplied by the solenoid valve. Most of the air after the drying plate 10 is heated and restored is blown outward through the ventilation filter, and a small portion is blown towards the bottom of the power cabinet 1 after the bottom opening and closing plate 28 is opened from the inside out, thereby dehumidifying the bottom of the power cabinet 1 with hot air and further improving the rust prevention reliability of the bottom of the power cabinet 1. The air blown outward through the ventilation filter, in conjunction with the self-cleaning component, can further improve the cleaning efficiency of the ventilation filter. When the humidity of the location of the power cabinet 1 is very high, causing the drying plate 10 to heat and reduce at a high frequency, the air inlet guide opening and closing device can be opened in time to separate the ventilation inlet 7 and the drying chamber 5, so that all the air after heating and reducing the drying plate 10 is blown out to the bottom of the power cabinet 1 through the bottom opening and closing plate 28 to dehumidify the bottom of the power cabinet 1 with hot air, making the power cabinet 1 better adaptable to this kind of installation location.

[0039] The second moisture-proof self-resetting component has the same structure as the first moisture-proof self-resetting component. The second moisture-proof self-resetting component is disposed within another drying and restoring chamber formed between the other side wall of the protective shell 2 and the power cabinet 1. Furthermore, the installation method of the second moisture-proof self-resetting component in the other drying and restoring chamber is the same as the installation method of the first moisture-proof self-resetting component in one drying and restoring chamber. The first moisture-proof self-resetting component and the second moisture-proof self-resetting component operate alternately.

[0040] The self-cleaning component includes a cleaning guide and a rotating cleaning component. The cleaning guide is disposed on the protective shell 2, and the rotating cleaning component is disposed on the cleaning guide. The cleaning guide includes a sliding groove 29 and a sliding block 30. The sliding groove 29 is horizontally fixed on the protective shell 2 above the ventilation inlet 7, and the sliding block 30 is slidably embedded in the sliding groove 29. Two sets of cleaning guides are provided, and the two sets of cleaning guides are symmetrically distributed parallel to each other, one directly above and one below the ventilation inlet 7.

[0041] The rotating cleaning component includes a brush roller 31, a rack 32, a gear 33, and a linear actuator 34. The top end of the rotating shaft of the brush roller 31 is rotatably mounted on a sliding block 30 of one of the cleaning guide components, and the bottom end of the rotating shaft of the brush roller 31 is rotatably mounted on a sliding block 30 of another cleaning guide component. The rack 32 is horizontally fixed on the protective shell 2, the gear 33 is fixedly fitted on the rotating shaft of the brush roller 31, and the gear 33 meshes with the rack 32. The bottom end of the linear actuator 34 is fixedly mounted on the protective shell 2, and the top end of the linear actuator 34 is connected to the sliding block 30. When the linear actuator 34 extends, it drives the gear 33 to slide to the left through the sliding block 30 and the brush roller 31. The gear 33 sliding to the left is pushed by the rack 32 to rotate circumferentially. The circumferentially rotating gear 33 drives the brush roller 31 to clean the ventilation filter. In conjunction with the hot air blown out from the drying chamber 5 through the ventilation filter, the cleaning efficiency of the ventilation filter is significantly improved.

[0042] Two sets of self-cleaning components are provided, symmetrically arranged on both sides of the protective shell 2. Each self-cleaning component corresponds to and cooperates with the first and second moisture-proof self-resetting components. The presence of the protective shell improves the power cabinet's resistance to external impacts.
