Description

Technical Field

[0001] The invention relates to the technical field of remote monitoring, and in particular to a remote monitoring and control system for a relay pump station for mud transportation. Background Art

[0002] In recent years, the desilting projects in urban areas, scenic spots and lakes that have emerged in the domestic dredging market have the characteristics that the mud discharge site is far away from the construction area and is not accessible to navigation, making it impossible to implement the conventional construction plan of grab dredger excavation, mud barge transportation, and suction dredger blowing and filling onshore. When using a single cutter suction dredger for construction, it is difficult to transport the dredged soil to the mud discharge site due to the limitation of the equipment head. It is a more reasonable choice to use a relay pump station in conjunction with a cutter suction dredger for long-distance pipeline transportation to blow and fill the dredged soil to the mud discharge site.

[0033] Furthermore, both the first display device 102 and the second display device 202 are touch display screens.

[0034] Specifically, the remote monitoring and control system of the relay pump station controls the start and stop, speed regulation, emergency stop, operation and fault status monitoring of the mud pump diesel engine 103 through the first PLC circuit board 101 at the relay pump station end; monitors the gear box oil pressure, oil temperature, and clutch status of the mud pump gearbox and clutch 104, and realizes clutch engagement and disengagement control, mud pump slip protection and mud pump speed display; monitors parameters such as the mud pump suction vacuum and discharge pressure of the mud pump body 105.

The ship end decompresses and decodes the transmitted data. Then it is displayed on the second display device 202; similarly, the second PLC circuit board 201 on the ship side sends the control command to the first PLC circuit board 101, which is sent to the first PLC circuit board 101 on the relay pump station side through the wireless data transmission module 301 and the transmission antenna 3, and the relevant actions are executed after decompression and decoding; the present application transmits the status information of the relay pump station to the construction ship in real time by wireless transmission, and the construction ship can also remotely control the equipment on the relay station by wireless transmission, and adjust the construction process in real time, so that the construction personnel can remotely monitor and control the relay pump end of the equipment connected to the relay pump station on the ship side of the construction ship, and timely understand the operating status of the relay pump station to ensure construction efficiency and safety.

[0036] Furthermore, a rotating rod 9 is horizontally rotatably connected inside the base plate 4, and a knob 901 and a worm 902 are respectively connected to both ends of the rotating rod 9. A first rotating rod 10 is vertically rotatably connected inside the base plate 4, and a first worm wheel 1001 meshing with the worm 902 is provided on the first rotating rod 10. A sleeve 1002 is connected to the lower side of the first rotating rod 10 via a first external thread, and the sleeve 1002 is movably abutted against the bottom of the back plate 6.

[0037] Furthermore, a plug hole 11 is provided on the bottom of the side plate 7 and the bottom plate 4 , and a plug rod 601 plugged into the plug hole 11 is fixedly provided on the lower side of the back plate 6 .

[0038] Furthermore, a connecting plate 12 is fixedly provided on the vertical plate 401, and a wedge block 121 is slidably connected to the outer side of the connecting plate 12 and is movably opposed to the side plate 7. A groove 122 matching the connecting plate 12 is formed on the wedge block 121, and an elastic element 123 is provided between the inner wall of the groove 122 and the connecting plate 12. A top block 602 is fixedly provided on the inner wall of the back plate 6 and is movably opposed to the inclined surface of the wedge block 121.

[0039] Furthermore, a second rotating rod 13 is vertically rotatably connected in the base plate 4, and a second worm gear 131 meshing with the worm 902 is provided at the bottom of the second rotating rod 13. The top of the second rotating rod 13 is connected to a positioning tube 132 through a second external thread, and a positioning groove 501 matching the positioning tube 132 is opened on the lower side of the top plate 5.

[0040] Specifically, when the relay pump station control box 1 and the ship control box 2 are working normally, the plug rod 601 of the back plate 6 is plugged into the plug holes 11 of the side plate 7 and the bottom plate 4 to fix and limit the side plate 7 and the bottom plate 4. At the same time, the positioning tube 132 is placed on the top of the second rotating rod 13 and plugged into the positioning groove 501 on the lower side of the top plate 5 to limit the top plate 5 from turning relative to the connecting plate 12, thereby realizing the installation limit of each plate body of the box body;

[0041] When it is necessary to repair or replace the electrical components inside the control box, the staff opens the box door 8 and rotates the knob 901 at the end of the rotating rod 9, so that the rotating rod 9 drives the worm 902 to mesh with the first worm gear 1001 on the first rotating rod 10 and the second worm gear 131 on the second rotating rod 13;

[0042] When the first worm gear 1001 drives the first rotating rod 10 to rotate, the sleeve 1002 threadedly connected to the first rotating rod 10 moves upward along its axial direction, so that the sleeve 1002 approaches the top wall of the movable groove 14; when the second worm gear 131 drives the second rotating rod 13 to rotate, the positioning tube 132 threadedly connected to the second rotating rod 13 moves downward and moves out of the positioning groove 501, thereby releasing the rotation restriction between the back plate 6 and the vertical plate 401; as the back plate 6 continues to move upward, the sleeve 1002 lifts the inner wall of the movable groove 14 to move the back plate 6 upward, and the back plate 6 pushes the top plate 5 to flip the top plate 5 relative to the vertical plate 401, and after the back plate 6 moves upward, it drives the insertion rod 601 away from the vertical plate 401. The socket 11 is opened to release the rotation restriction between the side panel 7 and the bottom panel 4. As the back panel 6 continues to move upward, the top block 602 on the back panel 6 abuts against the inclined surface of the wedge block 121, so that the wedge block 121 is forced to move laterally relative to the connecting plate 12, so that the side of the wedge block 121 away from the top block 602 pushes the side panel 7, so that the side panel 7 is flipped relative to the back panel 6, so that the side panels 7 and the top panel 5 of the box are unfolded, and the back panel 6 moves upward away from the bottom panel 4, so that the upper, lower, left and right positions of the electrical components installed on the back panel 6 are not blocked by other box panels, thereby reducing the difficulty of repairing or replacing the electrical components inside the control box and improving the work efficiency of the staff.

[0043] Reference Figure 2 and Figure 4 As a preferred technical solution of the present invention, a movable groove 14 for the movement of the sleeve 1002 is opened on the back plate 6, and a sealing plate 15 for blocking the movable groove 14 is fixed on the sleeve 1002; specifically, by arranging the sealing plate 15 on the side of the sleeve 1002, when the control box is working normally, the sleeve 1002 is placed at the bottom edge of the movable groove 14 and the movable groove 14 can be covered by the sealing plate 15, thereby preventing external dust from entering the interior of the box through the movable groove 14 and causing damage to the electrical components in the control box.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
