[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides an electrical cabinet drying structure, including an air inlet structure 1, a processing structure, and an exhaust structure 5. The processing structure is located between the air inlet structure 1 and the exhaust structure 5. Both the air inlet structure 1 and the exhaust structure 5 include a housing 24. A humidity sensor 21 is provided at the top of the inner cavity of the housing 24. The humidity sensor 21 can detect the humidity of the air entering the housing 24 in real time. Ventilation holes 20 are evenly provided on the side of the housing 24 away from the processing structure. Outside air can enter the inner cavity of the air inlet structure 1 through the ventilation holes 20, and the air in the inner cavity of the exhaust structure 5 can be discharged through the ventilation holes 20.

[0023] Ventilation mesh plates 22 are provided at both ends of the housing 24 near the processing structure, and ventilation mesh plate 23 is provided in the middle of the housing 24 near the processing structure. Sealing plates 18 are connected to both sides of the inner cavity of the housing 24 via electric telescopic rods 19. The sealing plates 18 are compatible with both ventilation mesh plates 22 and 23. The side of the sealing plate 18 near the processing structure is on the same plane as the sides of the ventilation mesh plates 22 and 23 away from the processing structure. The extension and retraction of the electric telescopic rods 19 can change the position of the sealing plates 18 connected to them. The sealing plates 18 can seal either ventilation mesh plate 22 or ventilation mesh plate 23, and can also scrape off dust adhering to either ventilation mesh plate 22 or ventilation mesh plate 23, thus cleaning the ventilation mesh plates 22 or ventilation mesh plate 23 and facilitating the use of the drying structure. The outer surface of the sealing plate 18 is provided with a sealing sheet, which can be made of rubber. By setting the sealing sheet, the sealing performance between the sealing plate 18 and the ventilation mesh plate 22 or the ventilation mesh plate 23 can be increased, thereby improving the sealing effect.

[0024] The processing structure includes a first drying component 2, a ventilation component 3, a second drying component 4, and a blower 6. Two ventilation mesh panels 23 are connected through the ventilation component 3. When the ventilation mesh panels 23 are not blocked, air enters the inner cavity of the ventilation component 3 through the air inlet structure 1, and the air in the inner cavity of the ventilation component 3 is discharged through the exhaust structure 5.

[0025] The first drying component 2 and the second drying component 4 have the same structure. The ends of the first drying component 2 and the second drying component 4 are connected to the ventilation mesh plate 22. When the ventilation mesh plate 22 connected to the first drying component 2 or the second drying component 4 is not blocked, the outside air enters the first drying component 2 or the second drying component 4 through the ventilation mesh plate 22. After the first drying component 2 or the second drying component 4 dries the air, the dried air is discharged through the exhaust structure 5. During this process, the air drying effect can be judged by comparing the detection results of the two humidity sensors 21. When the air drying effect cannot meet the requirements, the position of the sealing plate 18 is changed to stop the first drying component 2 or the second drying component 4 from working, and the second drying component 4 or the first drying component 2 is used to dry the air.

[0026] Both the first drying component 2 and the second drying component 4 have a moisture adsorption core 16 inside their cavities. When air passes through the moisture adsorption core 16, the moisture adsorption core 16 adsorbs the moisture in the air, thereby achieving the dehumidification of the air. The desiccant used in the moisture adsorption core 16 is a heat-regenerating desiccant.

[0027] Both the first drying component 2 and the second drying component 4 have air spray plates 14 connected to their tops and air concentrators 15 connected to their bottoms. A moisture adsorption core 16 is disposed between the air spray plate 14 and the air concentrator 15. The air outlet of the air spray plate 14 is in contact with the moisture adsorption core 16, and the air inlet of the air concentrator 15 is in contact with the moisture adsorption core 16. Both the air spray plate 14 and the air concentrator 15 are hollow structures, and holes are evenly provided at the bottom of the inner cavity of the air spray plate 14 and the top of the inner cavity of the air concentrator 15.

[0028] The air inlet end of the air spray plate 14 is connected to the air inlet pipe 10. The other end of the air inlet pipe 10 is connected to the air outlet end of the blower 6 through the air electric heater 8. The air inlet end of the blower 6 is connected to the connecting pipe 7. The other end of the connecting pipe 7 is located at the air outlet end of the exhaust structure 5. The air outlet end of the blower 6 is connected to the air inlet end of the air electric heater 8. The air outlet end of the air electric heater 8 is connected to the three-way valve 17. The other end of the air inlet pipe 10 is connected to the air outlet end of the three-way valve 17. The air outlet end of the three-way valve 17 is equipped with an electric ball valve 9. By setting the electric ball valve 9, the opening and closing of the air outlet end of the three-way valve 17 can be controlled, so that the flow direction of hot air can be controlled according to the needs when the drying structure is in use.

[0029] With the blower 6 in place, the blower 6 can blow the air around the exhaust outlet of the exhaust structure 5 into the air heater 8. The air heater 8 heats the air until it is heated to the regeneration temperature required for the thermal regeneration desiccant. The hot air can enter the inner cavity of the spray plate 14 through the air inlet pipe 10. The hot air in the inner cavity of the spray plate 14 can be sprayed onto the moisture adsorption core 16. The moisture adsorption core 16 can be heated to evaporate the absorbed moisture, thus achieving thermal regeneration of the moisture adsorption core 16. The evaporated water vapor can enter the inner cavity of the air gathering plate 15 with the air.

[0030] The air outlet of the air-concentrating plate 15 is connected to the exhaust pipe 13 via the air outlet pipe 25. The air inlet of the exhaust pipe 13 is connected to the three-way valve 11. The other end of the air outlet pipe 25 is connected to the air inlet of the three-way valve 11. The air inlet of the three-way valve 11 is equipped with an electric ball valve 12. The electric ball valve 12 can block the air inlet of the three-way valve 11, preventing the dehumidified air from being discharged through the air outlet pipe 25 when the drying structure is in use. When the air inlet of the three-way valve 11 is open, it facilitates the discharge of gas inside the air-concentrating plate 15. The air outlet of the exhaust pipe 13 is equipped with a one-way valve 26. Gas and water vapor inside the cavity of the air-concentrating plate 15 can enter the cavity of the exhaust pipe 13 through the air outlet pipe 25 and the three-way valve 11, and be discharged through the one-way valve 26.

[0031] Both the outer surfaces of the first drying component 2 and the second drying component 4 are covered with heat insulation pads. The outer surfaces of the three-way valve 17, the air inlet pipe 10, the three-way valve 21, the air outlet pipe 25, and the exhaust pipe 13 are also covered with heat insulation pads. By setting the heat insulation pads, the influence of hot air on other parts of the drying structure can be reduced, which facilitates the use of the drying structure. After the moisture adsorption core 16 is regenerated, the continued operation of the blower 6 can introduce cold air into the inner cavity of the drying component to cool down the moisture adsorption core 16, which facilitates the use of the moisture adsorption core 16.

[0032] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0033] The present application will be further described below through an embodiment.

[0034] When in use, the drying structure is installed inside the air inlet (such as heat dissipation hole) of the electrical cabinet. The end of the exhaust pipe 13 away from the drying structure is located outside the electrical cabinet. Users can install the end of the exhaust pipe 13 away from the drying structure in a suitable position according to their needs to avoid the gas discharged from the exhaust pipe 13 from affecting the electrical cabinet.

[0035] When the drying structure is in use, the gas entering the electrical cabinet enters the inner cavity of the air inlet structure 1 through the vent 20. The humidity sensor 21 in the inner cavity of the air inlet structure 1 detects the air humidity. If the air humidity meets the requirements, the air in the air inlet structure 1 passes through the second ventilation mesh 23 and enters the inner cavity of the ventilation component 3. The air in the inner cavity of the ventilation component 3 enters the inner cavity of the exhaust structure 5 through another second ventilation mesh 23. The air in the inner cavity of the exhaust structure 5 is discharged into the electrical cabinet through the vent 20 provided on it.

[0036] When the humidity sensor 21 inside the air intake structure 1 detects that the air humidity is too high and dehumidification is required, the electric telescopic rod 19 on the outside of the first drying component 2 extends. The electric telescopic rod 19 drives the sealing plate 18 connected to it to move until the sealing plate 18 blocks the second ventilation mesh plate 23. At this time, the air enters the inner cavity of the first drying component 2 through the first ventilation mesh plate 22 connected to the first drying component 2. The moisture adsorption core 16 inside the first drying component 2 adsorbs the air humidity. The dehumidified air enters the inner cavity of the exhaust structure 5 through another ventilation mesh plate 22 connected to the first drying component 2. The dehumidified air is discharged into the electrical cabinet through the vent 20 on the exhaust structure 5, so that the electrical cabinet can be kept dry. The humidity sensor 21 inside the exhaust structure 5 can detect the humidity of the dehumidified air in real time.

[0037] When the air humidity after dehumidification is insufficient, the electric telescopic rod 19 on the outside of the first drying component 2 retracts, causing the sealing plate 18 to move in the opposite direction until it resets, sealing the first drying component 2. Simultaneously, another electric telescopic rod 19 on the outside of the second drying component 4 extends, causing the connected sealing plate 18 to move until it seals the ventilation mesh plate 23. At this point, air enters the inner cavity of the second drying component 4, dehumidifying it. During dehumidification, the moisture adsorption core 16 inside the first drying component 2 can undergo thermal regeneration.

[0038] All standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional means such as bolts that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
