Description

Technical Field

[0001] The present invention relates to the technical field of visual switchgear protection, and specifically to a visual switchgear anti-condensation device and its usage method. Background Technique

[0002] Condensation refers to the phenomenon that water vapor in the air condenses into small water droplets on the surface of an object with a lower temperature due to reaching the saturation state when cooled. When the environment humidity and temperature difference of the visual switchgear are relatively large, condensation is extremely likely to occur. After the condensation occurs, it is easy to accumulate inside the switchgear, resulting in a reduction in the insulation performance of the insulation materials inside the switchgear. At the same time, it will cause corrosion to components inside the switchgear such as contacts and terminal blocks, reducing the operating stability of the switchgear. Therefore, it is necessary to set up an anti-condensation device inside the switchgear to clean the condensation.

[0003] After retrieval, the patent document with the publication number CN218828459U discloses a high and low voltage switchgear anti-condensation device. Through the coordinated use of an intermediate seat, a dehumidification layer, an elastic member, a sliding plate, a first conductor, a second conductor, and an alarm, the first conductor and the second conductor are respectively connected to the positive and negative poles of an external power supply through wires. As the dehumidification layer is used, the self-weight of the dehumidification layer gradually increases. When the dehumidification layer absorbs too much moisture and can no longer dehumidify, the sliding plate slides down until the first conductor contacts the second conductor, and the alarm immediately emits an alarm signal to remind the technician that the dehumidification layer needs to be replaced. In this way, the usage situation of the dehumidification layer can be understood more accurately, which is convenient for the technician to accurately replace the dehumidification layer.

[0004] However, the above device has the following defects in the anti-condensation work:

[0005] First of all, the above device absorbs the condensation water vapor through the dehumidification layer, but the dehumidification layer cannot be arranged everywhere inside the switchgear and its components. And the replacement of the dehumidification layer requires regular operation by the operator. When the operator is not on site during the operation of the alarm, the dehumidification layer cannot be replaced in time, resulting in the water vapor not being absorbed and continuing to stay inside the switch, which will still affect the internal components of the switchgear.

[0006] Secondly, only absorbing the condensation water vapor through the dehumidification layer has a poor effect, and the water vapor still accumulates inside the switchgear and cannot discharge the condensation outwards. Summary of the Invention

[0007] (1) Technical Problems to be Solved

[0008] Aiming at the deficiencies of the prior art, the present invention provides a visual anti-condensation device for switch cabinets and its usage method, which has the advantages of being able to effectively clean the condensation attached to the inner wall of the switch cabinet, discharge it outward, while ensuring the dryness inside the switch cabinet and ensuring the stable operation of the internal components of the switch cabinet. It solves the problem that the dehumidification layer absorbs the condensation water vapor, but the dehumidification layer cannot be arranged everywhere inside the switch cabinet, and the replacement of the dehumidification layer needs to be carried out regularly by the operator. When the alarm is working and the operator is not on site, the dehumidification layer cannot be replaced in time, resulting in the water vapor not being absorbed and remaining in the switch, which will still affect the internal components of the switch cabinet.

[0026] (III) Beneficial effects

[0027] Compared with the prior art, the present invention provides a visual switch cabinet anti-condensation device and a method of use, which has the following features:

[0028] Beneficial effects:

[0029] 1. The visualized switch cabinet anti-condensation device and its use method realize intelligent monitoring and control of the humidity inside the cabinet through the coordinated work of humidity sensor, single-chip microcomputer and exhaust fan. The humidity sensor monitors the cabinet humidity in real time. Once the humidity exceeds the standard, the single-chip microcomputer quickly starts the exhaust fan to exhaust the humid air, avoiding the limitation of relying solely on the dehumidification layer to absorb water vapor. There is no need for frequent manual inspection and replacement of the dehumidification layer. Even if the operator is not on site, the water vapor content in the cabinet can be continuously and effectively reduced, reducing the possibility of condensation formation from the source, and ensuring the stable operation of the internal components of the switch cabinet.

Compared with the existing technology that only relies on the dehumidification layer to absorb water vapor, it can not only remove the condensation more thoroughly, but also quickly dry the cabinet wall to prevent condensation from occurring again. In addition, the annular water tank and drain pipe design can discharge the scraped condensation in time to avoid secondary condensation, and fully guarantee the dry environment inside the switch cabinet.

Specific implementation manner

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1-7 , a visual switch cabinet anti-condensation device, including a cabinet body 1, a lower end of the back side of the cabinet body 1 is fixedly provided with an exhaust fan 2, an air inlet and an air outlet of the exhaust fan 2 are respectively communicated with an air inlet pipe 3 and an air outlet pipe 4, and an upper end of the air inlet pipe 3 penetrates into the cabinet body 1;

[0041] An upper end inner wall of the cabinet body 1 is fixedly provided with a support ring 5, four corners of the inner wall of the support ring 5 are fixedly provided with mounting plates 6, a vertical rod 7 is rotatably penetrated through each inner part of the mounting plates 6, a lower end of the rod wall of the vertical rod 7 is fixedly sleeved with a synchronous pulley 8, an outer side of a plurality of synchronous pulleys 8 is jointly driven and sleeved with a synchronous belt 9, an outer wall of the synchronous belt 9 is fixedly provided with an elastic rubber block 10, a bottom of the elastic rubber block 10 is fixedly provided with a scraper 11, a side of the scraper 11 close to the cabinet body 1 is in contact and cooperation with an inner side wall of the cabinet body 1, a drying component is arranged on a side of the scraper 11 away from the inner wall of the cabinet body 1, the drying component is used for drying the condensation on the inner wall of the cabinet body 1, a lower end of the outer wall of the scraper 11 is fixedly provided with a humidity sensor 13, a top of the inner wall of the cabinet body 1 is fixedly provided with a single-chip microcomputer 14, and the single-chip microcomputer 14 is electrically connected with the humidity sensor 13 and the exhaust fan 2.

[0042] When the switch cabinet is in use, the humidity sensor 13 detects the humidity inside the cabinet body 1. When the humidity is too high, the exhaust fan 2 starts to form suction, sucks the humid air inside the cabinet body 1 through the air inlet pipe 3, and then discharges it to the external environment through the air outlet pipe 4, thereby reducing the water vapor content inside the cabinet body 1 and reducing the possibility of condensation;

[0043] Subsequently, when the driving assembly drives the synchronous belt 9 to rotate, the synchronous belt 9 meshes with the synchronous pulley 8, causing the synchronous pulley 8 to drive the vertical rod 7 to rotate inside the mounting plate 6. Since the elastic rubber block 10 and the scraper 11 are fixed on the synchronous belt 9, the rotation of the synchronous belt 9 will drive the scraper 11 to move in a circular motion along the inner wall of the cabinet body 1, so that the scraper 11 can effectively scrape off the condensation attached to the inner wall of the cabinet body 1. At the same time, the humidity sensor 13 continuously monitors the humidity inside the cabinet body 1 and transmits the data to the single-chip microcomputer 14, enabling the subsequent drying assembly to operate and effectively dry the inside of the cabinet body 1.

[0044] In order to be able to effectively clean the condensation attached to the inner wall of the cabinet body 1, as Figures 4-6 shown, the drying assembly includes an exhaust fan 15 and a heating rod 16. A plurality of heat pipes 17 are fixedly penetrated inside the scraper 11 at intervals. One end of the scraper 11 in contact with the inner side wall of the cabinet body 1 is tapered. The end of the heat pipe 17 is in contact and cooperation with the inner side wall of the cabinet body 1. A plurality of heat pipes 17 are fixedly sleeved with a heat conduction cover 18 at the end away from the scraper 11. The heating rod 16 is fixedly arranged inside the heat conduction cover 18. The exhaust fan 15 is fixedly embedded in the side of the heat conduction cover 18, and the air outlet is arranged towards the heating rod 16. The heating rod 16 is electrically matched with the single-chip microcomputer 14.

[0045] When the single-chip microcomputer 14 receives the signal from the humidity sensor 13 and judges that the drying assembly needs to be started, it controls the heating rod 16 to be energized and generate heat. The heating rod 16 can be powered by a battery. At the same time, the exhaust fan 15 starts, blows air towards the heating rod 16, and the heated air enters the heat conduction cover 18. Since one end of the heat pipe 17 is connected to the heat conduction cover 18 and the other end is in contact with the inner side wall of the cabinet body 1, the heat of the hot air is quickly transferred to the inner wall of the cabinet body 1 through the heat pipe 17. The tapered end of the scraper 11 is in closer contact with the inner wall of the cabinet body 1. While the scraper 11 scrapes off the condensation, the heat flow heats and dries the area that has been scraped, accelerating the evaporation of water and improving the drying efficiency to prevent condensation from forming again.

[0046] In order to enable the scraper 11 to rotate stably and at the same time reduce the supply of external energy, as Figures 4-7As shown, at the upper end of the pipe wall of the air inlet pipe 3, a housing 12 is connected and provided. A cover plate 30 is covered on the side of the housing 12. The cover plate 30 is fixedly arranged by screwing with the outer wall of the housing 12. A driving component is arranged on the side of the housing 12. The driving component is used to drive the synchronous belt 9 to rotate. The driving component includes a driving gear 19 and a driving rod 20. The driving rod 20 rotates through the side of the housing 12. The driving gear 19 is fixedly sleeved on the upper end of the outer wall of the driving rod 20. A plurality of driving card slots 21 are arranged at intervals on the outer wall of the synchronous belt 9. The teeth of the driving gear 19 penetrate into the cabinet body 1 and are inserted into the driving card slots 21. A rotating hole for the rotation of the driving gear 19 is opened at the upper end of the side of the cabinet body 1. A synchronous transmission component is arranged on the rod wall of the driving rod 20. The synchronous transmission component is arranged inside the housing 12 and is used to start the driving component;

[0047] The synchronous transmission component includes a transmission rod 22 and a driving impeller 23. A cross rod 24 rotates through the inner wall of the housing 12. The driving impeller 23 is fixedly sleeved on the outer side of the cross rod 24. The transmission rod 22 rotates through the top of the housing 12. First bevel gears 25 and second bevel gears 26 are respectively fixedly sleeved on the closer ends of the transmission rod 22 and the cross rod 24. The first bevel gear 25 and the second bevel gear 26 are arranged in cooperation. First belt wheels 27 and second belt wheels 28 are respectively fixedly sleeved on the rod walls of the transmission rod 22 and the driving rod 20. A transmission belt 29 is jointly sleeved on the outer walls of the first belt wheel 27 and the second belt wheel 28. The blade end of the driving impeller 23 is inserted into the air inlet pipe 3.

[0048] When the exhaust fan 2 operates, air flows through the air inlet pipe 3. The air flow impacts the driving impeller 23, causing it to rotate. The driving impeller 23 drives the cross rod 24 to rotate. The second bevel gear 26 on the cross rod 24 rotates accordingly. Through meshing with the first bevel gear 25, the transmission rod 22 is driven to rotate. The first belt wheel 27 on the transmission rod 22 rotates, driving the second belt wheel 28 to rotate through the transmission belt 29, and further causing the driving rod 20 to rotate. The teeth of the driving gear 19 on the rod wall of the driving rod 20 mesh with the driving card slots 21 on the synchronous belt 9, thereby driving the synchronous belt 9 to move. At this time, the synchronous belt 9 can drive the scraper 11 to rotate, ensuring the stable progress of the drying work and the scraping work of the condensation.

[0049] In order to collect and discharge the scraped condensation, as Figure 1 shown, an annular water receiving groove 31 is opened at the bottom of the cabinet body 1. A drain pipe 32 is communicated with the groove wall of the annular water receiving groove 31. The end of the drain pipe 32 penetrates out of the cabinet body 1 and extends to the outside. The upper end of the side of the annular water receiving groove 31 close to the inner wall of the cabinet body 1 is arranged in an inclined plane.

[0050] After the squeegee 11 scrapes off the condensation on the inner wall of the cabinet body 1, the condensation will flow down along the inner wall of the cabinet body 1. The inclined surface design on one side of the annular water receiving groove 31 close to the inner wall of the cabinet body 1 facilitates the smooth flow of the condensation into the annular water receiving groove 31. The condensation collected in the annular water receiving groove 31 is discharged outside the cabinet body 1 through the drain pipe 32, preventing the condensation from accumulating inside the cabinet body 1 and further ensuring the dry environment inside the cabinet body 1.

[0051] In summary, for the visual switch cabinet anti-condensation device and its usage method, during use, first install the cabinet body 1 at the designated usage position. During the operation of the cabinet body 1, the humidity sensor 13 at the lower end of the outer wall of the squeegee 11 continuously monitors the humidity inside the cabinet body 1 in real time and transmits the humidity data to the single-chip microcomputer 14 at the top of the inner wall of the cabinet body 1 in real time.

[0052] When the humidity sensor 13 detects that the humidity inside the cabinet body 1 reaches or exceeds the preset humidity threshold, the single-chip microcomputer 14 immediately issues an instruction to start the exhaust fan 2. After the exhaust fan 2 is turned on, the humid air containing a large amount of water vapor inside the cabinet body 1 is sucked in through the air inlet pipe 3 and then discharged outside the cabinet body 1 through the air outlet pipe 4, thereby reducing the retention of water vapor inside the cabinet body 1, lowering the air humidity, and suppressing the generation of condensation at the source.

[0053] Meanwhile, during the process of the air inlet pipe 3 absorbing the air flow, the air flow entering the air inlet pipe 3 impacts the driving impeller 23. The driving impeller 23 is fixedly sleeved outside the cross bar 24 and starts to rotate after being impacted by the air flow, and the cross bar 24 rotates accordingly. The second bevel gear 26 at one end of the cross bar 24 meshes with the first bevel gear 25 at one end of the transmission rod 22. The rotation of the cross bar 24 drives the rotation of the second bevel gear 26, which in turn drives the rotation of the first bevel gear 25 and the transmission rod 22. The upper ends of the rod walls of the transmission rod 22 and the driving rod 20 are respectively sleeved with a first belt pulley 27 and a second belt pulley 28, and the two are connected through a transmission belt 29 for transmission. When the transmission rod 22 rotates, with the transmission of the first belt pulley 27, the transmission belt 29, and the second belt pulley 28, the driving rod 20 starts to rotate. When the driving rod 20 rotates, the driving gear 19 fixedly sleeved on the upper end of its outer wall rotates accordingly. The teeth of the driving gear 19 cooperate with the driving card slots 21 opened on the outer wall of the synchronous belt 9. The rotation of the driving gear 19 drives the synchronous belt 9 to drive. The synchronous belt 9 is smoothly driven under the support and guiding action of multiple synchronous wheels 8. The elastic rubber blocks 10 and the squeegee 11 fixed on the outer wall of the synchronous belt 9 also move accordingly. The squeegee 11 makes a circular revolution along the inner wall of the cabinet body 1 and can scrape off the condensation accumulated on the inner wall of the cabinet body 1.

[0054] While the squeegee 11 scrapes off the condensed moisture, the single-chip microcomputer 14 controls the exhaust fan 15 and the electric heating rod 16 to start. The electric heating rod 16 is energized to generate heat, and the exhaust fan 15 blows air towards the electric heating rod 16. After the air is heated, it enters the heat conduction cover 18. A plurality of heat pipes 17 are arranged at intervals inside the squeegee 11. One end of the heat pipe 17 is connected to the heat conduction cover 18, and the other end is in contact and cooperation with the inner side wall of the cabinet body 1. The heat of the hot air is efficiently transferred to the inner wall of the cabinet body 1 through the heat pipes 17. During the process of the squeegee 11 scraping off the condensed moisture, the heat flow heats and dries the area that has been scraped, accelerating the evaporation of moisture, keeping the inner wall of the cabinet body 1 dry, and further reducing the possibility of the re-generation of condensed moisture;

[0055] The condensed moisture scraped off by the squeegee 11 will flow down along the inner wall of the cabinet body 1. The annular water collecting groove 31 opened at the bottom of the cabinet body 1 is used to collect this condensed moisture. The upper end of the side of the annular water collecting groove 31 close to the inner wall of the cabinet body 1 is arranged in an inclined plane. This design helps the condensed moisture to flow into the annular water collecting groove 31 more smoothly. The condensed moisture collected in the annular water collecting groove 31 is discharged outside the cabinet body 1 through the drain pipe 32 communicated with the groove wall of the annular water collecting groove 31, avoiding the accumulation of condensed moisture inside the cabinet body 1, thereby comprehensively ensuring the dry environment inside the cabinet body 1 and ensuring the stable and reliable operation of the internal components of the switch cabinet.
