Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically a river dredging device for water conservancy engineering construction. Background Technology

[0002] Water conservancy projects are a collective term for projects such as flood control, irrigation, and power generation, as well as their supporting ancillary projects. Their core function is to control and regulate surface water and groundwater through the construction of hydraulic structures such as dams, dikes, and sluices, achieving the goal of mitigating harm and promoting benefits. One crucial aspect of water conservancy project construction is dredging river channels. By removing silt, garbage, and other impurities, water flow resistance is reduced, water flow is improved, and the normal flow rate of the river is restored.

[0003] Patent CN222990819U discloses a high-efficiency river dredging device for water conservancy engineering construction, including a hull with a propeller at the stern and a collection frame at the top. The hull is equipped with a lifting assembly, which in turn has an adjustment assembly. A cleaning shovel is connected to the bottom of the adjustment assembly. A rotating screw acts on a sliding plate, causing the sliding plate to move up and down on a guide rod and the screw, thus raising and lowering the cleaning shovel. This allows for adjustment of the cleaning shovel's height. The lifting and adjusting function of the lifting assembly enables the cleaning shovel to adapt to river channels of different depths, flow conditions, and silt accumulation. Whether the river is shallow or deep, operators can adjust the height of the cleaning shovel to ensure accurate contact with the silt layer and effective dredging.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] The cleaning shovel is inserted vertically or at an angle into the silt layer to peel off and remove the deposits. However, when the water surface of the area to be dredged is covered with aquatic plants (such as water hyacinth, duckweed, or reeds), the cleaning shovel may become entangled in the stems, leaves, or roots of the plants during its descent. This can cause a sudden increase in mechanical resistance, resulting in the cleaning shovel getting stuck. In some cases, the storage space of the cleaning shovel may even be occupied by aquatic plants, preventing the silt from entering the inner cavity of the cleaning shovel normally, ultimately affecting the dredging efficiency.

[0014] Preferably, a motor nine is fixedly connected to one side of the upper end of the pusher plate, and the output end of the motor nine is fixedly connected to one end of the winding roller.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The present invention discloses a river dredging device for water conservancy engineering construction. Utilizing a polymer-type dispersing component, when the water surface of the area to be dredged is covered with aquatic plants, multiple tightly clustered pusher plates are first inserted into the gaps between the aquatic plants. Subsequently, with the cooperation of the pusher cloth and the pusher plates, a continuously expanding enclosure is formed, which pushes the aquatic plants away. At this point, when the cleaning shovel is inserted into the water, it will not come into contact with the aquatic plants. This avoids the cleaning shovel from being entangled by the stems, leaves, or roots of the plants during its descent, which would cause a sudden increase in mechanical resistance, resulting in jamming of the cleaning shovel, or even the cleaning shovel's storage space being occupied by aquatic plants, preventing silt from entering the cleaning shovel's inner cavity normally. This, in turn, helps to improve dredging efficiency.

[0021] 2. The river dredging equipment for water conservancy engineering construction described in this invention utilizes a post-push reinforcement component. After the aquatic plants are pushed away, the tightening rope can press the aquatic plants firmly onto the surface of the pushing cloth, making it difficult for the aquatic plants pushed away by the pushing cloth to return to their original position under the action of wind or water flow, thus further avoiding the aquatic plants affecting the work of the cleaning shovel.

[0039] The mounting plate 6 has two bidirectional threaded rods 10 rotatably mounted on both sides of its lower end.

[0042] Specifically, in existing river dredging technologies, the cleaning shovel 13 is typically inserted vertically or obliquely into the silt layer to peel off and remove the silt. However, when the water surface of the area to be dredged is covered with aquatic plants such as water hyacinth, duckweed, or reeds, the cleaning shovel 13 may become entangled in the stems, leaves, or roots of the plants during its descent, causing a sudden increase in mechanical resistance. This can lead to the cleaning shovel 13 getting stuck, or even the storage space of the cleaning shovel 13 being occupied by aquatic plants, preventing the silt from entering the inner cavity of the cleaning shovel 13 normally, ultimately affecting the dredging efficiency.

[0043] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0044] The dredging vessel 1 travels along the river channel to be dredged. When the vessel reaches the dredging area, motor 7 drives gear 8 to lower rack 5, causing cleaning shovels 13 to descend and extend into the water. Then, motor 9 drives double-threaded rod 10 to bring the two cleaning shovels 13 closer together, shoveling up the silt. The cleaning shovels 13 are then removed from the water, and motor 8 drives gear 4 to rotate, causing rotating arm 2 to rotate 180 degrees, positioning the two cleaning shovels 13 above collection box 38. Motor 3 then drives cleaning shovels 13 to rotate, tilting them so that the collected silt falls into collection box 38. Since collection box 38 is positioned above the drain outlet of dredging vessel 1, excess water in the silt flows back into the river channel along filter screen 39, thus completing the dredging work.

[0045] When the water surface of the area to be dredged is covered with aquatic plants, the adjusting ring 17 can be raised by rotating the threaded rod 19 driven by motor 5 22. During the upward movement of the adjusting ring 17, the radial rod 20 will slide on the lifting ring 16 via the connecting rod 21, causing multiple pushing plates 24 to gather tightly. At the same time, motor 9 34 drives the winding roller 35 to rotate, winding up the pushing cloth 18. At this time, the multiple pushing plates 24 are above the aquatic plants. Then, the multiple pushing plates 24 are lowered by rotating the threaded rod 15 driven by motor 4 14, so that the pushing plates 24 will extend into the gaps of the aquatic plants. Then, the adjusting ring 17 is driven to move. As the water descends, the multiple pushing plates 24 disperse, and simultaneously, the winding roller 35 unwinds the pushing cloth 18. With the cooperation of the pushing cloth 18 and the pushing plates 24, a continuously expanding enclosure is formed, which pushes the aquatic plants away. At this point, when the cleaning shovel 13 is inserted into the water, it will not come into contact with the aquatic plants. This avoids the cleaning shovel 13 from being entangled by the stems, leaves, or roots of the plants during its descent, which would cause a sudden increase in mechanical resistance, resulting in jamming of the cleaning shovel 13. In some cases, the storage space of the cleaning shovel 13 may be occupied by aquatic plants, preventing the silt from entering the inner cavity of the cleaning shovel 13 normally. This, in turn, helps to improve the sludge removal efficiency.

[0046] In this embodiment, as Figures 3-7 As shown, the push plate 24 is also equipped with a reinforcement component after being pushed open;

[0047] The reinforcement assembly after being opened includes two rotating rods 40 rotatably mounted on the outside of the pusher plate 24. The ends of the rotating rods 40 are rotatably mounted with take-up and release wheels 28, and the two adjacent take-up and release wheels 28 on the two adjacent pusher plates 24 are together wound with a pressure rope 23. A rotating rod 26 is rotatably mounted on one side of the lower end of the rotating rods 40. A pressure block 27 is fixedly connected to one end of the rotating rod 26. Two pressure rods 37 are rotatably mounted on one side of the pusher plate 24.

[0048] Motor 10 36 is fixedly connected to both sides of the upper end of the push plate 24. The output ends of motor 10 36 on both sides are fixedly connected to one end of rotating rod 2 40 on both sides. Motor 11 41 is fixedly connected to one side of the lower end of rotating rod 2 40. The output end of motor 11 41 is fixedly connected to one side of the take-up and release wheel 28. Motor 6 25 is fixedly connected to one side of the lower end of rotating rod 2 40. The output end of motor 6 25 is fixedly connected to one end of rotating rod 1 26.

[0049] One end of the pressure rod 37 is fixedly connected to a gear 2 30, and two adjacent gears 2 30 mesh with each other. One side of the push plate 24 is fixedly connected to a motor 7 29, and the output end of the motor 7 29 is fixedly connected to the gear 2 30.

[0050] Specifically, in the above embodiments, although the aquatic plants can be pushed outwards with the cooperation of the pusher plate 24 and the pusher cloth 18, if the surrounding wind is strong or the water flow is rapid, the pushed aquatic plants are prone to swaying and may then reset at the bottom of the pusher cloth 18 and the pusher plate 24 and be in the inner cavity of the enclosure formed by the pusher cloth 18 and the pusher plate 24, thereby interfering with the work of the cleaning shovel 13 again.

[0051] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0052] When the pusher plate 24 moves, motor 11 41 also drives the take-up and release wheel 28 to rotate, winding and releasing the pressure rope 23 to keep it taut. After the aquatic plants are pushed away, motor 10 36 drives the rotating rod 2 40 to rotate, causing the pressure rope 23 to descend and approach the pusher cloth 18. The pressure rope 23 will then push the aquatic plants onto the surface of the pusher cloth 18. Subsequently, motor 6 25 drives the rotating rod 1 26 to rotate, and motor 7 29 drives the pressure rod 37 to rotate. Adjacent pressure rods 37 will rotate simultaneously in opposite directions due to the transmission of gear 2 30. The pressure block 27 and the pressure rod 37 together squeeze the end of the pressure rope 23, so that the aquatic plants that are in contact with the pusher cloth 18 will be pressed tightly onto the surface of the pusher cloth 18 by the pressure rope 23. This makes it difficult for the aquatic plants pushed away by the pusher cloth 18 to return to their original position under the action of wind or water flow, further preventing the aquatic plants from affecting the work of the cleaning shovel 13.

[0053] Working principle: The dredging vessel 1 travels in the river channel to be dredged. When the dredging vessel 1 reaches the area to be dredged, the rack rod 5 is lowered by the rotation of gear 8 driven by motor 7, causing the cleaning shovel 13 to descend and extend into the water. Then, the two cleaning shovels 13 are brought closer together by the rotation of the double-threaded rod 10 driven by motor 9, shoveling up the silt. The cleaning shovels 13 are then moved out of the water. The rotating arm 2 is rotated 180 degrees by the rotation of gear 32 driven by motor 31, positioning the two cleaning shovels 13 above the collection box 38. Then, the cleaning shovels 13 are rotated by motor 32, tilting them so that the collected silt falls into the collection box 38. Since the collection box 38 is located above the drain outlet of the dredging vessel 1, excess water in the silt flows back into the river channel along the filter screen 39, thus achieving the dredging work of the river channel. When the water surface of the area to be dredged is covered with aquatic plants, the adjusting ring 17 can be raised by rotating the threaded rod 19 driven by motor 5 22. During the upward movement of the adjusting ring 17, the radial rod 20 will slide on the lifting ring 16 via the connecting rod 21, causing multiple pushing plates 24 to gather tightly. At the same time, motor 9 34 drives the winding roller 35 to rotate, winding up the pushing cloth 18. At this time, the multiple pushing plates 24 are above the aquatic plants. Then, the multiple pushing plates 24 are lowered by rotating the threaded rod 15 driven by motor 4 14, so that the pushing plates 24 will extend into the gaps of the aquatic plants. Then, the adjusting ring 17 is driven to move. As the water descends, the multiple pushing plates 24 disperse, and simultaneously, the winding roller 35 unwinds the pushing cloth 18. With the cooperation of the pushing cloth 18 and the pushing plates 24, a continuously expanding enclosure is formed, pushing the aquatic plants outwards. At this point, when the cleaning shovel 13 is inserted into the water, it will not come into contact with the aquatic plants. This prevents the cleaning shovel 13 from becoming entangled in the stems, leaves, or roots of the plants during descent, thus avoiding a sudden increase in mechanical resistance, jamming, or even the storage space of the cleaning shovel 13 being occupied by aquatic plants, preventing silt from entering the inner cavity of the cleaning shovel 13 normally. This improves sludge removal efficiency. When the pushing plates 24 move, the motor 11 41 also drives the take-up and unwinding wheel 28 to rotate, winding and unwinding the tensioning rope 23 to keep it taut at all times. After the aquatic plants are pushed away, motor 10 36 drives rotating rod 2 40 to rotate, causing the clamping rope 23 to descend and approach the pushing cloth 18. The clamping rope 23 will then push the aquatic plants onto the surface of the pushing cloth 18. Subsequently, motor 6 25 drives rotating rod 1 26 to rotate, and motor 7 29 drives pressure rod 37 to rotate. Adjacent pressure rods 37 will rotate simultaneously in opposite directions due to the transmission of gear 2 30. The pressure block 27 and the pressure rod 37 together squeeze the end of the clamping rope 23, so that the aquatic plants that are in contact with the pushing cloth 18 will be pressed tightly onto the surface of the pushing cloth 18 by the clamping rope 23. This makes it difficult for the aquatic plants pushed away by the pushing cloth 18 to reset under the action of wind or water flow, further preventing the aquatic plants from affecting the work of the cleaning shovel 13.
