Description

Technical Field

[0001] This invention relates to the field of trailing suction hopper dredger technology, and in particular to a control device based on a domestically produced AMS system for trailing suction hopper dredgers. Background Technology

[0002] In the dredging and dredging industry, key dredging control equipment (such as PLC controllers and sensors) has long been mostly imported, and the software operating environment and database have all been developed based on Windows. The AMS system is a web-based tool that supports the provisioning, management, and monitoring of Apache Hadoop clusters. In response to this situation, the localization of the AMS system for trailing suction hopper dredgers has emerged.

[0003] The AMS system requires a PLC control cabinet. Also known as a programmable logic controller (PLC) control cabinet, it controls and monitors various mechanical equipment, sensors, and actuators used during the dredging process of a trailing suction hopper dredger, enabling automated operation. Since the PLC control cabinet on a trailing suction hopper dredger frequently operates on the water surface, desiccant needs to be placed inside to absorb moisture entering the cabinet through the air inlet. However, the desiccant requires cleaning and replacement after a period of use, increasing the workload for staff. Furthermore, frequent opening of the cabinet can allow excessive moisture or dust to enter, affecting the cabinet's performance. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a control device based on the domestic AMS system of a trailing suction hopper dredger.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The material changing body has material changing grooves evenly distributed around its circumference, and the outer wall of the material changing body is interference-fitted with the inner wall of the movable groove.

[0010] Preferably, the internal capacity of the material changing trough and the material placing trough is the same.

[0011] Preferably, the feeding assembly includes a drive motor fixed in the material changing seat, a screw connected to the output shaft of the drive motor, a sleeve threadedly connected to the screw, and a connecting rod movably disposed between the sleeve and the mesh frame.

[0012] Preferably, the transmission assembly includes a movable gear mounted on a rotating rod and a rack that meshes with the movable gear, and a push rod is provided between the rack and the sleeve.

[0013] Preferably, the movable gear includes two one-way gears, each of which includes a fixed disk fixedly connected to the rotating rod and a rotating disk rotatably connected to the outside of the fixed disk. The fixed disk has a groove, and a locking block is rotatably connected to the groove via a pin. A torsion spring for driving the locking block to reset is sleeved on the pin.

[0015] Preferably, the waste material holder is inclinedly disposed inside the control cabinet, the top of the waste material holder is fixedly connected to the protective shell, and the top of the waste material holder has an opening that communicates with the protective shell.

[0016] Compared with the prior art, the present invention provides a control device based on the domestic AMS system of a trailing suction hopper dredger, which has the following beneficial effects:

[0017] 1. The control device based on the domestic AMS system of the trailing suction hopper dredger automatically controls the material changing component to work when the air humidity inside the cabinet exceeds the preset value through the sensor. When the material changing component is working, it drives the feeding component to move through the transmission component, so that the desiccant particles placed in the mesh frame automatically fall into the waste seat. At the same time, the unused desiccant particles in the storage box are replenished into the mesh frame through the material changing component on the material changing seat. This can realize the automatic cleaning and replacement of desiccant particles in the control cabinet, reduce the workload of the staff, and ensure the continuous and stable operation of the control cabinet.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] Example: Refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A control device based on a domestically produced AMS system for a trailing suction hopper dredger includes a control cabinet 1 with an internal PLC control module, a sensor for monitoring humidity inside the control cabinet 1, an air inlet 101 on the top of the control cabinet 1, a filter screen 102 at the air inlet 101, a protective shell 2 inside the control cabinet 1 at the air inlet 101, a mesh frame 3 rotatably connected inside the protective shell 2 via a pin, desiccant granules laid flat inside the mesh frame 3, a material changing seat 4 fixed on the side of the protective shell 2, a material changing component for changing desiccant granules and a material feeding component for driving the mesh frame 3 to flip on the material changing component and the material feeding component are connected by a transmission component, a storage box 5 is connected to the top of the material changing seat 4, and a waste material seat 13 is provided inside the control cabinet 1 on the lower side of the mesh frame 3.

[0031] Specifically, external air enters the control cabinet 1 through the air inlet 101. The filter 102 intercepts and filters impurities in the air. When the air passes through the mesh frame 3, the desiccant particles placed inside the mesh frame 3 can absorb moisture in the air, preventing moisture from damaging the electrical components inside the cabinet. Over time, the desiccant particles gradually lose their ability to absorb moisture. When the sensor inside the control cabinet 1 detects that the air humidity inside the cabinet exceeds the preset value, the system automatically controls the material changing component to work. When the material changing component works, it drives the feeding component through the transmission component, causing the desiccant particles placed inside the mesh frame 3 to automatically fall into the waste material seat 13. Unused desiccant particles in the storage box 5 are replenished to the mesh frame 3 through the material changing component on the material changing seat 4. This enables automatic cleaning and replacement of desiccant particles inside the control cabinet 1, reducing the workload of the staff and ensuring the continuous and stable operation of the control cabinet 1.

[0032] Reference 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, the top of the material changing seat 4 is provided with a receiving port 401 that communicates with the bottom opening of the storage box 5, the material changing seat 4 is provided with an active groove 402 for the operation of the material changing component, and the side of the material changing seat 4 is provided with a discharge port 403 that cooperates with the wire mesh frame 3.

[0033] Furthermore, the mesh frame 3 is provided with a material trough 301 for placing desiccant particles, and the two ends of the mesh frame 3 are respectively provided with a feed inlet 302 and a discharge outlet 303.

[0034] Furthermore, the material changing assembly includes a rotating rod 6 rotatably connected to the material changing seat 4 and a material changing body 601 disposed on the rotating rod 6. The material changing body 601 has material changing grooves 6011 evenly distributed in a circle, and the outer wall of the material changing body 601 is interference-fitted with the inner wall of the movable groove 402.

[0035] Furthermore, the material changing tank 6011 has the same internal capacity as the material placement tank 301.

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

[0037] Furthermore, the transmission assembly includes a movable gear 8 mounted on the rotating rod 6 and a rack 9 meshing with the movable gear 8, with a push rod 901 disposed between the rack 9 and the sleeve 702.

[0038] Furthermore, 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. The fixed disk 801 has a groove, and a locking block 8011 is rotatably connected to the groove through a pin. A torsion spring for driving the locking block 8011 to reset is sleeved on the pin. The rotating disk 802 has slots 8021 evenly distributed around the circumference. The locking block 8011 is movably connected to the slots 8021. The rack frame 9 is provided with a rack plate that meshes with the two one-way gears.

[0039] Furthermore, the feeding assembly also includes a rotating rod 10 rotatably connected to the material changing seat 4. The rotating rod 10 is provided with a drum 1001 and a driven gear 1002. The rotating rod 6 is provided with an incomplete gear 602 that intermittently meshes with the driven gear 1002. A pull rope 11 is wound and connected to the drum 1001. A baffle 111 is connected to the end of the pull rope 11 away from the drum 1001. The baffle 111 is slidably connected to the mesh frame 3 and is used to block the discharge port 303. An elastic element 112 is provided between the baffle 111 and the mesh frame 3. A guide seat 12 that is slidably connected to the pull rope 11 is fixed on the mesh frame 3.

[0040] Specifically, when the sensor inside the control cabinet 1 detects that the air humidity inside the cabinet exceeds the preset value, the system automatically controls the material changing component to work, the drive motor 7 runs, the output shaft of the drive motor 7 drives the screw 701 to rotate, the sleeve 702 moves along the axial direction of the screw 701, and the sleeve 702 pushes the mesh frame 3 to rotate through the connecting rod 703. The mesh frame 3 flips and tilts around the pin that is connected to the protective shell 2.

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

[0042] When the rotating rod 6 rotates, the incomplete gear 602 meshes with the driven gear 1002 for transmission. The driven gear 1002 drives the drum 1001 to rotate through the rotating rod 10. The drum 1001 winds up the pull rope 11, and the pull rope 11 applies tension to the baffle 111. The baffle 111 moves upward along the mesh frame 3, causing the desiccant particles that have failed to dispose of in the mesh frame 3 to be discharged from the outlet 303 of the mesh frame 3. The desiccant particles fall into the waste seat 13.

[0043] Subsequently, the drive motor 7 drives the screw 701 to rotate in the opposite direction, and the sleeve 702 moves back. The sleeve 702 drives the mesh frame 3 to reset and move down through the connecting rod 703. During this period, the other rack plate of the rack frame 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 with the driven gear 1002, and the drum 1001 no longer applies tension to the pull rope 11. The baffle 111 moves back instantaneously under the pull of the elastic element 112 and re-blocks the discharge port 303 of the mesh frame 3. As the mesh frame 3 flips downward, the material changing trough 6... Unused desiccant granules in 011 are connected to the feed inlet 302 of the mesh frame 3 through the discharge port 403. The desiccant granules in the material exchange trough 6011 enter the material placement trough 301. Since the mesh frame 3 is still tilted, the internal capacity of the material exchange trough 6011 and the material placement trough 301 is the same. The desiccant granules entering the material placement trough 301 automatically slide down and are finally spread flat in the mesh frame 3. The desiccant granules absorb the moisture in the air that subsequently enters the control cabinet 1. After the material exchange body 601 rotates, its material exchange trough 6011 continues to receive unused desiccant granules in the storage box 5.

[0044] Reference Figure 1 , Figure 2 and Figure 3 As a preferred technical solution of the present invention, the waste base 13 is further inclinedly arranged in the control cabinet 1, the top of the waste base 13 is fixedly connected to the protective shell 2, and the top of the waste base 13 has an opening that communicates with the protective shell 2; specifically, the desiccant particles falling from the mesh frame 3 fall into the waste base 13 and automatically slide down the inclined waste base 13 and move out of the control cabinet 1.

[0045] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
