[0030] Embodiment: Refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , a control device based on a domestic AMS system of a trailing suction hopper dredger, comprising a control cabinet 1 internally provided with a PLC control module. A sensor for monitoring humidity is provided inside the control cabinet 1. An air inlet 101 is opened at the top of the control cabinet 1, and a filter screen 102 is provided at the air inlet 101. A protective shell 2 is provided inside the control cabinet 1 at the air inlet 101. A wire mesh frame 3 is rotatably connected inside the protective shell 2 through a pin shaft. Desiccant particles are laid flat inside the wire mesh frame 3. A material changing seat 4 is fixedly provided on the side of the protective shell 2. A material changing assembly for replacing the desiccant particles and a blanking assembly for driving the wire mesh frame 3 to flip are provided on the material changing seat 4. A transmission assembly is provided between the material changing assembly and the blanking assembly. A storage tank 5 is communicated with the top of the material changing seat 4. A waste seat 13 is provided inside the control cabinet 1 below the wire mesh frame 3.

[0031] Specifically, external air enters the interior of the control cabinet 1 through the air inlet 101. The filter screen 102 intercepts and filters impurities in the air. When the air passes through the grid frame 3, the desiccant particles placed in the grid frame 3 can absorb the water vapor in the air, preventing the water vapor in the air from damaging the electrical components in the cabinet. As time goes by, the ability of the desiccant particles to absorb water gradually fails. The sensor in the control cabinet 1 monitors that the air humidity in the cabinet exceeds the preset value, and the system automatically controls the material changing assembly to work. When the material changing assembly works, it drives the blanking assembly to act through the transmission assembly, so that the desiccant particles placed in the grid frame 3 automatically fall into the waste seat 13, and the unused desiccant particles in the storage bin 5 are supplemented into the grid frame 3 through the material changing assembly on the material changing seat 4, which can realize the automatic cleaning and replacement of the desiccant particles in the control cabinet 1, reduce the workload of the staff, and ensure the continuous and stable operation of the control cabinet 1.

[0032] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , as a preferred technical solution of the present invention, further, a material receiving port 401 communicating with the bottom opening of the storage bin 5 is provided at the top of the material changing seat 4. An activity groove 402 for the operation of the material changing assembly is provided in the material changing seat 4. A blanking port 403 matching with the grid frame 3 is provided on the side of the material changing seat 4.

[0033] Further, a material placing groove 301 for placing desiccant particles is provided on the grid frame 3. Feed ports 302 and discharge ports 303 are respectively provided at both ends of the grid frame 3.

[0034] Further, the material changing assembly includes a rotating rod 6 rotatably connected to the material changing seat 4 and a material changing body 601 provided on the rotating rod 6. Material changing grooves 6011 are provided on the material changing body 601 and are evenly distributed in a circular pattern. The outer wall of the material changing body 601 is in interference fit with the inner wall of the activity groove 402.

[0035] Further, the internal capacities of the material changing grooves 6011 and the material placing grooves 301 are the same.

[0036] Further, the blanking assembly includes a driving motor 7 fixed in the material changing seat 4, a screw rod 701 connected to the output shaft of the driving motor 7, a sleeve 702 threadedly connected to the screw rod 701, and a connecting rod 703 movably arranged between the sleeve 702 and the grid frame 3.

[0037] Further, the transmission assembly includes a movable gear 8 provided on the rotating rod 6 and a rack 9 meshing with the movable gear 8. A push rod 901 is provided between the rack 9 and the sleeve 702.

[0038] Further, the movable gear 8 includes two one-way gears. Each one-way gear includes a fixed disk 801 fixedly connected to the rotating rod 6 and a rotating disk 802 rotatably connected to the outside of the fixed disk 801. A groove is formed in the fixed disk 801. A clamping block 8011 is rotatably connected to the groove through a pin shaft. A torsion spring for driving the clamping block 8011 to reset is sleeved on the pin shaft. A plurality of card slots 8021 evenly distributed in a circumferential manner are formed in the rotating disk 802. The clamping block 8011 is movably connected in the card slots 8021. A rack plate meshing with the two one-way gears is arranged on the rack frame 9.

[0039] Further, the blanking assembly further includes a rotating rod 10 rotatably connected to the material changing seat 4. A winding drum 1001 and a driven gear 1002 are arranged on the rotating rod 10. An incomplete gear 602 intermittently meshing with the driven gear 1002 is arranged on the rotating rod 6. A pull rope 11 is wound and connected to the winding drum 1001. One end of the pull rope 11 away from the winding drum 1001 is connected to a baffle plate 111. The baffle plate 111 is slidably connected to the wire mesh frame 3 and is used for blocking the discharge port 303. An elastic element 112 is arranged between the baffle plate 111 and the wire mesh frame 3. A guide seat 12 slidably connected to the pull rope 11 is fixedly arranged on the wire mesh frame 3.

[0040] Specifically, when the sensor in the control cabinet 1 monitors that the air humidity in the cabinet exceeds the preset value, the system automatically controls the material changing assembly to work, the driving motor 7 runs, the output shaft of the driving motor 7 drives the screw rod 701 to rotate, the sleeve 702 moves along the axial direction of the screw rod 701, and the sleeve 702 pushes the wire mesh frame 3 to rotate through the connecting rod 703. The wire mesh frame 3 tilts and flips with the pin shaft connected to the protective shell 2 as the center;

[0041] When the sleeve 702 moves, it drives the rack frame 9 to mesh and drive with the movable gear 8 through the push rod 901. One of the rack plates of the rack frame 9 meshes and drives with one of the one-way gears, so that the rotating rod 6 rotates clockwise. The rotating rod 6 drives the material changing body 601 to rotate. The material changing groove 6011 of the material changing body 601 picks up the desiccant particles in the storage box 5 and rotates;

[0042] When the rotating rod 6 rotates, the incomplete gear 602 meshes and drives with the driven gear 1002. The driven gear 1002 drives the winding drum 1001 to rotate through the rotating rod 10. The winding drum 1001 winds up the pull rope 11. The pull rope 11 applies a pulling force to the baffle plate 111. The baffle plate 111 moves upward along the wire mesh frame 3, so that the ineffective desiccant particles in the wire mesh frame 3 are discharged from the discharge port 303 of the wire mesh frame 3, and the desiccant particles fall into the waste seat 13;

[0043] Subsequently, the drive motor 7 drives the screw rod 701 to rotate in the reverse direction, and the sleeve 702 moves back. The sleeve 702 drives the wire rack 3 to reset and move downward through the connecting rod 703. During this period, the other rack plate of the rack 9 meshes with the movable gear 8, so that the movable gear 8 still drives the rotating rod 6 to rotate clockwise. At this time, the incomplete gear 602 no longer meshes and drives with the driven gear 1002, and the drum 1001 no longer applies a pulling force to the pulling rope 11. The baffle 111 instantaneously moves back under the pulling of the elastic element 112 and re-blocks the discharge port 303 of the wire rack 3. As the wire rack 3 flips downward, the unused desiccant particles in the material-changing groove 6011 are communicated with the feed port 302 of the wire rack 3 through the blanking port 403, and the desiccant particles in the material-changing groove 6011 enter the material-placement groove 301. And at this time, since the wire rack 3 still maintains an inclined state, the internal capacities of the material-changing groove 6011 and the material-placement groove 301 are the same, and the desiccant particles entering the material-placement groove 301 automatically slide down and finally spread flat in the wire rack 3. The desiccant particles absorb the moisture in the air subsequently entering the control cabinet 1, and the material-changing groove 6011 of the rotated material-changing body 601 continues to pick up the unused desiccant particles in the storage box 5.

[0044] Refer to Figure 1 、 Figure 2 and Figure 3 , as a preferred technical solution of the present invention, further, the waste seat 13 is inclined and arranged in the control cabinet 1, the top of the waste seat 13 is fixedly connected to the protective shell 2, and an opening communicating with the protective shell 2 is opened at the top of the waste seat 13; specifically, the desiccant particles falling from the wire rack 3 fall into the waste seat 13 and automatically slide out of the control cabinet 1 along the inclined waste seat 13.

[0045] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
