[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 - Figure 6 As shown, a control box with dehumidification function mainly consists of an air compressor station system 1, a control cabinet 2, a cabinet door 3, and a control component 4. The control component 4 is installed on the inner wall of the control cabinet 2, while the cabinet door 3 is connected to the control cabinet 2 through a locking assembly and a hinge assembly, thereby realizing the electrical control function of the air compressor station system 1.

[0031] In the middle of the side wall of the control cabinet 2, we made an opening and installed a dehumidification pipe 5, which is fixed to the control cabinet 2 via a connecting flange 6. Multiple fixing posts 7 are provided on the outer wall of the dehumidification pipe 5, and transmission components 8 are installed at the upper ends of these fixing posts 7. One of the fixing posts 7 has a fixing bracket 11 on its outer cover, and a drive shaft 10 is located at the opening of the fixing bracket 11. The outer end of the drive shaft 10 is connected to a stepper motor and then to the transmission components 8. The other ends of the multiple transmission components 8 are connected to drive rings 9. The moving shaft of the transmission components 8 passes through the fixing posts 7 and is connected to a sector-shaped sealing door 14. The forward and reverse rotation of the drive rings 9, achieved by the forward and reverse rotation of the stepper motor, drives the opening and closing of the sector-shaped sealing door 14. Through the coordinated work of the drive shaft 10, the drive rings 9, and the transmission components 8, the opening and closing operation of the sector-shaped sealing door 14 is realized.

[0032] A dehumidifier 15 is installed at the outer end of the dehumidification pipe 5. By opening the fan-shaped sealing door 14 and using the dehumidifier 15, dehumidification of the control cabinet 2 can be effectively performed. A desiccant storage cover 16 is provided at the inner end of the dehumidification pipe 5, and an inlet 17 is opened at the upper part of its inner end. The desiccant storage cover 16 stores desiccant, which works together with the dehumidifier 15 to achieve the dehumidification function.

[0033] The control cabinet 2 is fixed to the dehumidification pipe 5 and the connecting flange 6 with bolts, and a sealing ring is provided at the connection point to ensure airtightness. The fixing column 7 is welded to the dehumidification pipe 5, and its pipe hole is aligned with the round hole on the dehumidification pipe 5 to ensure the stability of the structure.

[0034] The transmission assembly 8 consists of multiple transmission arms connected by a rotating shaft, with the tail transmission arm fixed to the moving shaft. The moving shaft is inserted into the pipe hole of the fixed column 7 and fixed to the sector-shaped sealing door 14 by bolts. Sealing strips are provided at the joints of the multiple sector-shaped sealing doors 14, forming a circular sealing door to ensure a sealing effect.

[0035] A waist hole 12 is provided on the dehumidification pipe 5. A sliding limiter 13 is inserted into the waist hole 12. The sliding limiter 13 is fixed to the transmission ring 9 to limit the rotation of the transmission ring 9 and prevent excessive rotation, thereby protecting the transmission assembly 8 from damage.

[0036] The dehumidifier 15 is bolted to the dehumidification pipe 5, and a filter screen is bolted to its front end to ensure air quality during the dehumidification process. The desiccant storage cover 16 is integrated with the dehumidification pipe 5 and has an arc-shaped edge, which is not only aesthetically pleasing but also better suited to the internal space of the control box.

[0037] The feed inlet 17 is connected to the control cabinet 2. Dehumidification of the inside of the control cabinet 2 is achieved through dehumidifier, and waste agent is stored through the dehumidifier storage cover 16, ensuring the continuity and environmental friendliness of the dehumidification process.

[0038] Ensure the control box is correctly installed and connected to the power supply. Check that the control cabinet 2, dehumidification pipe 5, connecting flange 6, and transmission assembly 8 are securely connected, and ensure that all sealing rings and sealing strips are intact to guarantee airtightness. Open the cabinet door 3 of the control cabinet 2 using the locking and hinge assembly. Add an appropriate amount of desiccant to the desiccant storage hood 16 through the inlet 17.

[0039] Close cabinet door 3 and ensure it is secured by the locking assembly. Turn on the power switch of dehumidifier 15 to start its operation. Open the fan-shaped sealing door 14, which can be operated via transmission assembly 8. Transmission assembly 8 is connected to fan-shaped sealing door 14 via a moving shaft. Transmission ring 9 and transmission assembly 8 work together to achieve the opening and closing operation of fan-shaped sealing door 14.

[0040] The dehumidifier 15 starts working, and air enters it through the dehumidification pipe 5. The dehumidifier 15 filters the air through a filter screen to ensure air quality during the dehumidification process. Moisture in the air is absorbed by the desiccant, achieving dehumidification within the control cabinet 2. Regularly check the desiccant level and replace it as needed. Check the operating status of the transmission assembly 8, the sector-shaped sealing door 14, and the sliding limit component 13 to ensure normal operation. Clean the filter screen to maintain the efficient operation of the dehumidifier 15. Turn off the power switch of the dehumidifier 15. Close the sector-shaped sealing door 14, ensuring it is completely closed and sealed.
