[0027] The utility model uses the exhaust fan 32 to extract air into the control cabinet body 20, and the outside air enters the control cabinet body 20 through the first air inlet 31, the second air inlet 22, and the air inlet pipe 30, so that the air in the control cabinet body 20 is discharged from the air outlet 21 to realize air circulation. The desiccant box 10 is supported by the support block 34 in the air inlet pipe 30. The desiccant box 10 adsorbs moisture in the air passing through the air inlet pipe 30 to ensure the dryness of the air entering the control cabinet body 20. At the same time, the air is not heated, so that the temperature in the control cabinet body 20 is normal, thereby ensuring the stability of the operation of the electronic components. After working for a long time, the desiccant box 10 can no longer continue to adsorb moisture in the air. At this time, the control component 40 controls the two support blocks 34 to slide outward synchronously, so that the desiccant box 10 on the support block 34 falls into the collection tube 60, and then controls the support block 34 to reset, and then the new desiccant box 10 is placed on the support block 34 through the feeding component 70.

[0032] The control plate 43 is in sliding contact with the outer wall of the intake pipe 30 away from the first air inlet 31 , and one side of the long side of the trapezoidal block 44 is connected to the control plate 43 ; one end of the compression spring 45 is connected to the fixed plate 36 and the other end is connected to the intake pipe 30 .

[0033] like Figure 3 、 4 As shown in Figures 5, 6, and 9, the control plate 43 is driven to move up and down by the driving unit 50. When the control plate 43 is moved up and down, the slide rod 42 slides in the slide hole to ensure the stability of the control plate 43. The lifting of the driving plate drives the trapezoidal block 44 to move up and down. When the trapezoidal block 44 contacts the control column 46, the control column 46 is pushed to move, so that the support block 34 and the control column 46 move synchronously. When the support block 34 moves, the compression spring 45 is compressed. When the trapezoidal block 44 is separated from the control column 46, the compression spring 45 loses its restriction and pushes the support block 34 to reset under the action of the elastic force.

[0034] Furthermore, the drive unit 50 includes: a slide groove 51, which is vertically arranged on the fixed seat 41, and a rack 52 is slidably arranged in the slide groove 51, and the upper end of the rack 52 is connected to the control board 43; a drive motor 53, which is arranged on the fixed seat 41, and a driving wheel 54 is arranged on the output shaft of the drive motor 53, and the driving wheel 54 is engaged with the rack 52.

[0035] like Figure 3 、 4 As shown, the driving motor 53 drives the driving wheel 54 to rotate, so that the rack 52 slides in the sliding groove 51, driving the control panel 43 to rise and fall.

[0036] Further, the feeding assembly 70 comprises: a feeding cylinder 71 vertically arranged in the control cabinet body 20, a plurality of desiccant boxes 10 are stored in the feeding cylinder 71, the control plate 43 is in sliding contact with the feeding cylinder 71 away from the side of the air inlet pipe 30, a discharge port 72 is formed in the bottom of the side wall of the feeding cylinder 71 close to the air inlet pipe 30, a feeding port 73 is formed in the air inlet pipe 30 corresponding to the discharge port 72, through ports 74 are formed in the upper and lower sides of the control plate 43, and an opening 75 is formed in the side wall of the feeding cylinder 71 away from the discharge port 72 corresponding to the discharge port 72; a mounting seat 76 is arranged at the bottom of the feeding cylinder 71; and a driving cylinder 77 is arranged on the mounting seat 76, and the piston rod of the driving cylinder 77 is directed towards the opening 75 and is provided with a push plate 78.

[0037] The top opening 75 of the feeding cylinder 71, the staff puts a plurality of new desiccant boxes 10 into the feeding cylinder 71 through the top opening 75; the shapes of the feeding port 73, the through port 74 and the discharge port 72 are matched with the desiccant box 10.

[0038] As shown in Figure 3 , 5 , the unused desiccant boxes 10 are stored in the feeding cylinder 71, when feeding is needed, the driving motor 53 drives the control plate 43 to descend until the upper through port 74 is flush with the discharge port 72 and the feeding port 73, then the driving cylinder 77 drives the push plate 78 to move, the desiccant box 10 at the bottom of the feeding cylinder 71 is pushed through the discharge port 72, the through port 74 and the feeding port 73 into the air inlet pipe 30 on the support block 34, then the driving cylinder 77 drives the push plate 78 to reset, the driving motor 53 drives the control plate 43 to slightly ascend, so that the through port 74 is staggered with the feeding port 73, and the feeding port 73 is blocked by the control plate 43.

[0039] Further, the push plate 78 is horizontally provided with a baffle 79 on the side close to the driving cylinder 77.

[0040] As shown in Figure 7 , 8 , the baffle 79 is arranged on the side close to the driving cylinder 77, so that when the push plate 78 pushes the desiccant box 10 at the bottom of the feeding cylinder 71 to move, the baffle 79 supports the upper desiccant box 10, so that the upper desiccant box 10 does not fall and is stuck between the push plate 78 and the driving cylinder 77, so that the driving cylinder 77 cannot drive the push plate 78 to reset.

[0041] Further, a cleaning port 61 is formed in the lower side of the side wall of the collection cylinder 60 close to the inner wall of the control cabinet body 20, and a cleaning door 23 is arranged on the side wall of the control cabinet body 20 at the cleaning port 61.

[0042] As shown in Figure 1 , 3As shown, the staff opens the cleaning door 23 and can take out the discarded desiccant box 10 from the cleaning port 61 .

[0043] Working principle: Start the exhaust fan 32 to extract air from the control cabinet body 20, and the outside air enters the control cabinet body 20 through the air inlet pipe 30, so that the air in the control cabinet body 20 is discharged from the air outlet 21 to realize air circulation. The desiccant box 10 is supported by the support block 34 in the air inlet pipe 30. The desiccant box 10 absorbs moisture in the air passing through the air inlet pipe 30 to ensure that the air entering the control cabinet body 20 is dry; after working for a long time, the desiccant box 10 can no longer absorb moisture in the air. At this time, the drive motor 53 is started to drive the driving wheel 54 to rotate, driving the rack 52, the control board 43, and the trapezoidal block 44 to descend, pushing the control column 46 and the support block 34 to move outward synchronously, so that the desiccant box 10 supported on the control block falls into the collection tube 6 0; when the support block 34 moves, the compression spring 45 is compressed. When the trapezoidal block 44 separates from the control column 46, the compression spring 45 pushes the support block 34 to reset under the action of the elastic force; the control plate 43 continues to descend until the through port 74 on the upper side of the control plate 43 cooperates with the feed port 73 and the discharge port 72, and then the drive cylinder 77 is started to drive the push plate 78 to move, pushing the desiccant box 10 at the bottom of the feeding cylinder 71 through the discharge port 72, the through port 74, and the feed port 73 into the air inlet pipe 30 and located on the support block 34, and then the drive cylinder 77 drives the push plate 78 to reset, and the drive motor 53 drives the control plate 43 to rise slightly, so that the through port 74 and the feed port 73 are staggered, and at the same time, the feed port 73 is blocked by the control plate 43 to ensure that the equipment can operate for a long time. The next time the desiccant cartridge 10 needs to be replaced, the drive motor 53 drives the control board 43 to rise, so that the through port 74 on the lower side of the control board 43 cooperates with the feed port 73 and the discharge port 72. After the material replacement is completed, the drive motor 53 drives the control board 43 to slightly descend, so that the through port 74 and the feed port 73 are staggered, and the feed port 73 is blocked by the control board 43, and this process is repeated.
