[0035] Please see Figures 1-6 This application provides a new technical solution: a dredging device for water conservancy projects, including a dredging vessel 1, an adjustment mechanism 2 installed at the bow of the dredging vessel 1, an installation frame 6 provided on the adjustment mechanism 2, for driving the installation frame 6 to rotate back and forth around the bow of the dredging vessel 1, and a cleaning cutter head 7 provided at the end of the installation frame 6 for cleaning the silt on the riverbed.

[0036] The cleaning head 7 is connected to a sludge suction pipe 12, and an oil pump 8 is installed on the sludge suction pipe 12. The oil pump 8 is used to pump the riverbed silt cleaned by the cleaning head 7 to the riverbank through the sludge suction pipe 12. The dredging device can effectively remove the riverbed silt and move it to the bank, ensuring unobstructed river flow and improving water quality. The mounting frame 6 can rotate left and right, allowing the cleaning head 7 to operate in different positions, expanding the dredging range and improving dredging efficiency.

[0037] In some embodiments, the adjustment mechanism 2 includes a mounting frame 21, which is arranged in a side "U" shape. A first rotating shaft 23 is rotatably connected to the opening of the mounting frame 21. A fixing sleeve 22 is fixedly installed on the first rotating shaft 23. A mounting base 25 is fixedly installed on the side of the fixing sleeve 22 near the opening of the mounting frame 21. A second rotating shaft 24 is rotatably connected to the mounting base 25. One end of the mounting frame 6 is fixedly installed on the second rotating shaft 24. The mounting frame 6 can move up and down around the second rotating shaft 24. The adjustment mechanism 2 can realize the movement of the mounting frame 6 in the up, down and left and right directions around the adjustment mechanism 2, which enhances the operational flexibility of the equipment and adapts to different water depths and terrain conditions.

[0038] In some embodiments, a connector 61 is fixedly installed on the mounting frame 6, and a cable 43 is connected to the connector 61. The end of the cable 43 is connected to a cable retraction mechanism, which is mounted on the dredging vessel 1 and is used to pull the mounting frame 6 up and down around the second rotating shaft 24. When the cable retraction mechanism is activated, the up and down movement of the mounting frame 6 around the second rotating shaft 24 can be controlled by pulling or releasing the cable 43. The cable retraction mechanism provides precise control over the up and down movement of the mounting frame 6, ensuring that the cleaning head 7 can operate in the optimal position, improving work efficiency, simplifying the operation process, and reducing labor costs.

[0039] In some embodiments, the cable retraction and deployment mechanism includes a cable mounting frame 4 fixedly installed on the dredging vessel 1. A cable frame 42 is rotatably connected to the cable mounting frame 4, and a cable 43 is wound around the cable frame 42. A second motor 41 is provided on one side of the cable frame 42 to drive the cable frame 42 to rotate on the cable mounting frame 4. The second motor 41 realizes the automation of cable retraction and deployment, reduces manual intervention, and improves the continuity and reliability of the work.

[0040] In some embodiments, a support frame 5 is provided at the bow of the dredging vessel 1, and a pulley 51 is provided at the upper end of the support frame 5, and the cable 43 is wound around the pulley 51.

[0041] In some embodiments, a transmission mechanism 3 is provided on the mounting frame 21, and the first rotating shaft 23 passes through the inside of the transmission mechanism 3 and is rotatably connected inside the transmission mechanism 3. The transmission mechanism 3 is used to drive the first rotating shaft 23 to rotate back and forth. The transmission mechanism 3 provides a stable power source for the first rotating shaft 23, ensuring that the mounting frame 6 can move back and forth smoothly, thus enhancing the stability of the dredging process.

[0042] In some embodiments, the transmission mechanism 3 includes a transmission housing 31, a first rotating shaft 23 is rotatably connected within the transmission housing 31, a swing rod 32 is fixedly mounted on the first rotating shaft 23, a connecting rod 33 is rotatably connected to the end of the swing rod 32, the other end of the connecting rod 33 is rotatably connected to a turbine 34, the connecting rod 33 is eccentrically arranged on the turbine 34, and the turbine 34 is rotatably connected within the transmission housing 31.

[0043] In this embodiment, a worm gear 36 is meshed with one side of the turbine 34, and a first motor 35 is connected to one end of the worm gear 36 to drive the worm gear 36 to rotate. In use, the first motor 35 is started to drive the worm gear 36 to rotate, which in turn drives the turbine 34 to rotate. The connecting rod 33 drives the swing rod 32 to swing left and right, thereby realizing the reciprocating rotation of the first rotating shaft 23. The cleaning speed can be adjusted according to actual needs, which improves the flexibility and adaptability of dredging work.

[0044] In some embodiments, the cleaning head 7 is mounted on a mounting plate 72, which has two sludge extraction ports that are connected to the sludge extraction pipe 12. The cleaning head 7 is driven to rotate by a third motor 71 mounted on a mounting frame 6. The rotating cleaning head 7 can more effectively cut and agitate the riverbed silt, and work with the sludge extraction ports to quickly extract the silt, thus improving cleaning efficiency. The design of two sludge extraction ports helps to distribute pressure, reduce the possibility of blockage of a single sludge extraction port, and ensure the smooth progress of the sludge extraction process.

[0045] In some embodiments, the dredging pipe 12 is provided with several sets of floats 121 to make the dredging pipe 12 float on the water surface. The floats 121 ensure that the dredging pipe 12 is always kept near the water surface, avoiding the pipe from sinking or twisting due to the impact of water flow, thus ensuring the smooth progress of the dredging work. The dredging vessel 1 is provided with a propeller 11 to drive the dredging vessel 1 to move on the water surface. The propeller 11 gives the dredging vessel 1 good maneuverability, enabling it to move flexibly in different waters, expanding the operating range, and also facilitating the deployment and recovery of the equipment.

[0046] In operation, a dredging device for water conservancy projects controls the propeller 11 mounted on a dredging vessel 1 to propel it towards the river section requiring dredging. Upon reaching the target location, it stops and adjusts its attitude. A cable mechanism pulls the mounting frame 6 up and down around a second rotating shaft 24, bringing the dredging head 7 as close as possible to the riverbed silt layer. The first motor 35 and worm gear 36 in the adjusting mechanism 2 drive the turbine 34 and connecting rod 33, causing the first rotating shaft 23 to rotate left and right, thus moving the dredging head 7 back and forth in the riverbed silt. A third motor 71 is activated to drive the dredging head 7 to rotate, cutting and agitating the riverbed silt, loosening it and mixing it with water to form slurry. At this time, the two suction ports on the dredging head 7 begin to suck in the slurry. The oil pump 8 is started, and the slurry sucked in by the dredging head 7 is transported to a designated location on the riverbank through the suction pipe 12.
