[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a new constant pressure water supply frequency conversion control cabinet, including a control cabinet 1, a dustproof structure 2 and a dehumidification structure 3. A heat dissipation slot 4 is provided on the side wall of the control cabinet 1. The dustproof structure 2 and the dehumidification structure 3 are both fixedly arranged on the side wall of the control cabinet 1, and the dustproof structure 2 and the dehumidification structure 3 are both arranged corresponding to the heat dissipation slot 4. The dustproof structure 2 is used to remove dust and filter the gas entering the control cabinet 1, and the dehumidification structure 3 is used to dehumidify and filter the gas entering the cabinet;

[0028] Specific reference Figure 2 , Figure 4 and Figure 6 In this embodiment, the dehumidification structure 3 includes a mounting plate 5, a desiccant containing shell 6 and a fixing mechanism 7. The mounting plate 5 is fixedly arranged on the inner wall of the control cabinet 1. The mounting plate 5 is provided with a mounting slide groove 8. The desiccant containing shell 6 is provided with a mounting protrusion 9. The desiccant containing shell 6 is slidably arranged in the mounting slide groove 8 through the mounting protrusion 9. The side wall of the desiccant containing shell 6 is a hollow structure. The desiccant containing shell 6 contains desiccant. The mounting protrusion 9 of the desiccant containing shell 6 is provided with a fixing groove. The mounting plate 5 is provided with a fixing hole. The fixing mechanism 7 is arranged on the side wall of the control cabinet 1, and the fixing mechanism 7 is arranged opposite to the fixing hole. The fixing mechanism 7 is adapted to the fixing groove. The fixing mechanism 7 is configured to penetrate the fixing hole and be embedded in the fixing groove to fix the desiccant containing shell 6.

[0029] During specific use, the installation protrusion 9 of the desiccant containing shell 6 is aligned with the installation slide groove 8, and the desiccant containing shell 6 and the mounting plate 5 are installed along the sliding rod of the installation slide groove 8. After installation, the desiccant containing shell 6 is fixed by the fixing mechanism 7 to ensure the installation stability of the desiccant containing shell 6. In addition, the desiccant containing shell 6 can be conveniently disassembled to replace the desiccant through the setting of the fixing mechanism 7.

[0030] Specific reference Figure 2 and Figure 3In this embodiment, the fixing mechanism 7 includes a fixing plate 10, a guide plate 11, a limiting plate 12 and a fixing rod 13. The fixing plate 10 and the guide plate 11 are both fixedly arranged on the side wall of the control cabinet 1. A through slot 14 is provided on the fixing plate 10. One end of the fixing rod 13 penetrates and slides in the through slot 14. The other end of the fixing rod 13 penetrates the guide plate 11 and is slidably arranged. One end of the fixing rod 13 penetrates the guide plate 11 and penetrates the fixing hole and is adapted to the fixing slot. A connecting plate 15 is fixedly arranged in the middle of the fixing rod 13. A fixing spring 16 is provided between the connecting plate 15 and the guide plate 11. The fixing spring 16 is sleeved on the fixing rod 13. The limiting plate 12 is rotatably connected to the fixing rod 13 and the connecting plate 15. The limiting plate 12 is configured to be adjustable in position relative to the through slot 14 by rotation.

[0031] During specific use, when the limit plate 12 rotates to the top of the through slot 14, the fixing spring 16 applies force to the fixing rod 13, and the limit plate 12 can smoothly pass through the through slot 14. At this time, one end of the fixing rod 13 can pass through the fixing hole and be embedded in the fixing slot; when the limit plate 12 is moved away from the top of the through slot 14, the limit plate 12 cannot pass through the through slot 14, so that the limit plate 12 is blocked by the fixing plate 10, preventing the lower end of the fixing rod 13 from passing through the fixing hole and being embedded in the fixing slot. At this time, the desiccant container shell 6 can be conveniently removed.

[0032] Specific reference Figure 3 , Figure 4 and Figure 5 In this embodiment, the desiccant containing shell 6 includes a detachable shell 17 and a cover 18, a positioning groove is provided on the side wall of one of the shell 17 and the cover 18, and a positioning column 19 is provided on the side wall of the other one, and the shell 17 and the cover 18 are connected by the positioning column 19 and the positioning groove.

[0033] Optionally, in order to improve the installation stability of the desiccant container shell 6, two groups of mounting plates 5 are symmetrically provided, and the mounting grooves 8 of the two groups of mounting plates 5 are arranged facing each other. Both the shell 17 and the cover body 18 are provided with mounting protrusions 9, and the mounting protrusions 9 are arranged one by one with the mounting grooves 8.

[0034] When in use, the positioning columns 19 of the housing 17 and the cover 18 are aligned with the positioning grooves and connected as a whole, and then the assembled desiccant containing shell 6 is installed in the installation slide groove 8 of the installation plate 5.

[0035] Specific reference Figure 6 In this embodiment, the length of the installation slot 8 is less than the length of the installation plate 5, and the rear end of the installation slot 8 fails to penetrate the installation plate 5. When the desiccant containing shell 6 is slidably installed along the installation slot 8, the rear wall of the desiccant containing shell 6 is blocked and limited by the rear wall of the installation slot 8, indicating that the desiccant containing shell 6 is installed in place. At this time, the fixing rod 13 just corresponds to the fixing slot.

[0036] Specific reference Figure 6 and Figure 7 In this embodiment, the dustproof structure 2 includes a mounting shell 20 and a dustproof net 21. The mounting shell 20 is a U-shaped structure. The mounting shell 20 is fixedly mounted on the side wall of the control cabinet 1. A mounting groove 22 is provided on one side of the mounting shell 20 close to the side wall of the control cabinet 1. The dustproof net 21 is embedded in the mounting groove 22. When the dustproof net 21 needs to be replaced, it only needs to be pulled out of the mounting groove 22.

[0037] Specific reference Figure 2 In this embodiment, electrical components for controlling water supply are installed in the control cabinet 1, and a heat dissipation fan 23 is provided on the top wall of the control cabinet 1. The heat dissipation efficiency inside the control cabinet 1 is ensured by the cooperation of the heat dissipation fan 23 and the heat dissipation slot 4.

[0038] The working principle of the utility model is as follows:

[0039] (1) Under the action of the heat dissipation fan 23, the external air is filtered and dust-removed by the dust-proof structure 2 and then enters the control cabinet 1 through the heat dissipation slot 4. Before entering the control cabinet 1, it is dried by the desiccant of the dehumidification structure 3 to prevent water vapor from entering the control cabinet 1.

[0040] (2) When the dust screen 21 needs to be disassembled and cleaned, the dust screen 21 can be directly pulled out from the mounting groove 22 of the mounting shell 20;

[0041] (3) When the desiccant needs to be replaced, first apply force to the fixing rod 13 to drive one end of the fixing rod 13 to slide out from the fixing groove of the mounting protrusion 9. When the limit plate 12 moves to the top of the fixing plate 10, rotate the limit plate 12 to make the limit plate 12 and the through groove 14 misaligned. Under the cooperation of the fixing plate 10 and the limit plate 12, one end of the fixing rod 13 is kept away from the mounting protrusion 9, and the fixing spring 16 is in a stretched state at this time; at this time, pull the desiccant container shell 6 out of the mounting groove 8 of the mounting plate 5, remove the cover body 18, and then replace the desiccant.
