Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and specifically to a mobile dredging mechanism for water conservancy projects. Background Technique

[0002] Water conservancy projects are used to control and allocate surface water and groundwater in nature, and are built for the purpose of eliminating disasters and bringing benefits, and are also called water projects. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet the needs of humans. Building water conservancy projects can control water flow, prevent flood disasters, regulate and distribute the water volume of surface water and groundwater, and meet the needs of people's life and production. Water conservancy projects usually need to use dredging devices to remove impurities such as silt in pipelines, inspection wells or river channels.

[0003] In the prior art, dredging boats are usually used for river dredging. When the dredging boat is working, the bridge at the front end of the bow is placed below the water surface, and the cutter in front of the bridge is used to loosen the mud surface underwater, and it is pumped out from underwater by the negative pressure suction generated by the mud pump, and then transported to an area thousands of meters away to achieve the purpose of channel cleaning and reclamation from the sea. However, there are garbage such as fishing nets deposited in the silt at the bottom of the river. During the dredging process, the fishing nets will be wrapped around the cutter, delaying the project progress, and in severe cases, the cutter will be damaged. For this reason, we propose a mobile dredging mechanism for water conservancy projects. Summary of the Invention

Detailed implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a mobile dredging mechanism for water conservancy projects, including a hull 1, a gantry 9 is arranged on the hull 1, a connecting plate 10 is rotatably arranged at one end of the hull 1, a wire reel 11 is arranged on the hull 1, a steel wire rope 12 is arranged on the wire reel 11, one end of the steel wire rope 12 bypasses the gantry 9 and is connected to the connecting plate 10, and a dredging mechanism 2 is arranged at the end of the connecting plate 10. By winding and unwinding the steel wire rope 12 by the wire reel 11, the connecting plate 10 can be driven to move, so as to put the dredging mechanism 2 into the river or move it out of the water surface;

[0029] The dredging mechanism 2 includes a connection box 21 arranged at the end of the connecting plate 10, a plurality of cutting units 3 are arranged on the connection box 21, a drive assembly 4 is arranged on the connection box 21, and the drive assembly 4 drives the plurality of cutting units 3 to loosen the river silt.

[0030] The drive assembly 4 includes a waterproof motor 41 arranged at one end of the connection box 21, a drive shaft 42 is arranged at the output end of the waterproof motor 41, the drive shaft 42 is rotatably arranged in the connection box 21, sprockets 43 are arranged on the outer sides of the drive shaft 42 and the synchronizing shaft 32, and a chain 44 matched with the sprockets 43 is arranged in the housing 31.

[0031] The cutting unit 3 includes a housing 31 disposed on the connection box 21. A synchronous shaft 32 is rotatably provided on the housing 31. The synchronous shaft 32 is in transmission connection with a driving assembly 4. A transmission shaft 33 is movably connected to the synchronous shaft 32. A winch 34 is provided at the end of the transmission shaft 33. During dredging, the waterproof motor 41 is started to drive the drive shaft 42 to rotate. The drive shaft 42 drives the synchronous shaft 32 to rotate through a sprocket 43 and a chain 44. The synchronous shaft 32 drives the winch 34 to rotate through the transmission shaft 33 for dredging.

[0032] A moving assembly 5 is provided on the winch 34. A blade 6 is provided on the moving assembly 5. An elastic guiding member 7 is provided outside the transmission shaft 33. When the winch 34 rotates, the moving assembly 5 can move up and down under the action of the elastic guiding member 7. A deflection assembly 8 capable of deflecting the winch 34 relative to the synchronous shaft 32 is provided on the housing 31.

[0033] The synchronous shaft 32 and the transmission shaft 33 are connected by a universal joint to ensure that the synchronous shaft 32 can still drive the transmission shaft 33 to rotate after the winch 34 deflects. The deflection assembly 8 includes an annular top block 81 provided on the housing 31. A fixing block 82 cooperating with the annular top block 81 is provided outside the transmission shaft 33. When the transmission shaft 33 rotates, it can drive the fixing block 82 to move along the edge of the annular top block 81. When the fixing block 82 moves to the protruding part of the annular top block 81, the winch 34 can be deflected. Any two adjacent fixing blocks 82 are symmetrically arranged relative to the transmission shaft 33. Through the symmetrical arrangement between adjacent fixing blocks 82, adjacent winches 34 are close to each other on one side and away from each other on the other side during deflection, and a tearing effect can be achieved.

[0034] A chute 51 is formed on the winch 34. The moving assembly 5 includes a plurality of sliders 52 movably arranged in the chute 51. The blade 6 is provided on the side of the slider 52 away from the housing 31. A guide rod 53 is provided on the other side of the slider 52. A return spring 54 is provided between the sliders 52 and between the slider 52 and the bottom of the chute 51.

[0035] The elastic guiding member 7 includes a fixing disk 71 provided outside the transmission shaft 33. A connecting telescopic rod 72 is provided between the fixing disk 71 and the housing 31. The two ends of the connecting telescopic rod 72 are respectively rotatably connected to the fixing disk 71 and the housing 31. A guiding telescopic rod 73 is provided on the fixing disk 71. A moving disk 74 is provided at the end of the guiding telescopic rod 73. A conical spring 75 is provided on the moving disk 74. The smaller end of the conical spring 75 is fixedly connected to the moving disk 74.

[0036] A pressing block 76 is fixedly arranged on the outer side of the transmission shaft 33. The pressing block 76 is divided into an inclined section and a flat section. A fixing rod 77 which is used in cooperation with the pressing block 76 is arranged on the moving disk 74. A ball is arranged at the end of the fixing rod 77. When the transmission shaft 33 drives the pressing block 76 to rotate, the inclined section of the pressing block 76 can press the fixing rod 77 to drive the moving disk 74 to move until the fixing rod 77 moves to the flat section. At this time, the conical spring 75 is compressed into a flat state, and this flat surface is in a spiral shape. When the conical spring 75 is compressed into a flat surface, the guide rod 53 on the slider 52 will move along the spiral shape due to the rotation of the winch 34. Furthermore, the guide rod 53 drives the slider 52 to move, and the slider 52 drives the blade 6 to move. When a fishing net is generated on the winch 34, the fishing net can be cut by the reciprocating movement of the blade 6. And during the rotation of the winch 34, the conical spring 75 always performs reciprocating telescopic movements, which can cooperate with the winch 34 to mix the muddy water, facilitating the dredging operation.

[0037] In summary, during the dredging operation, first, the wire rope 12 is unreeled by the winch 11 so that the connecting plate 10 places the dredging mechanism 2 into the river channel. Then, the waterproof motor 41 is started to drive the drive shaft 42 to rotate. The drive shaft 42 drives a plurality of synchronous shafts 32 to rotate through the chain 44 and the sprocket 43. The synchronous shafts 32 drive the winch 34 to rotate through the rotating shaft. When the transmission shaft 33 rotates, the transmission shaft 33 drives the fixed block 82 to move along the edge of the annular top block 81. When the fixed block 82 moves to the protruding part of the annular top block 81, the winch 34 can be deflected. Any two adjacent fixed blocks 82 are symmetrically arranged relative to the transmission shaft 33. Through the symmetrical arrangement between the adjacent fixed blocks 82, when the adjacent winches 34 are deflected, one side of them approaches each other and the other side moves away from each other, which can achieve the tearing effect. At the same time, when the transmission shaft 33 rotates, it drives the pressing block 76 to rotate. The inclined section of the pressing block 76 can press the fixing rod 77 to drive the moving disk 74 to move until the fixing rod 77 moves to the flat section. At this time, the conical spring 75 is compressed into a flat state, and this flat surface is in a spiral shape. When the conical spring 75 is compressed into a flat surface, the guide rod 53 on the slider 52 will move along the spiral shape due to the rotation of the winch 34. Furthermore, the guide rod 53 drives the slider 52 to move, and the slider 52 drives the blade 6 to move. When a fishing net is generated on the winch 34, the fishing net can be cut by the reciprocating movement of the blade 6. Therefore, during the dredging process, the winches 34 on the plurality of cutting units 3 can be deflected when rotating. When a fishing net is wound on the winch 34, the fishing net can be torn by the deflection between the plurality of winches 34. And the deflection of the winch 34 during dredging can make the coverage area of the winch 34 wider when excavating the silt, and the excavation effect is better. Moreover, the conical spring 75 can reciprocate telescopically during work. When the conical spring 75 is compressed to a flat surface, it can act as the track of the guide rod 53 to make the blade 6 move up and down. And during the telescopic process of the conical spring 75, it can also assist in mixing the muddy water and improve the working efficiency.
