Description

Technical Field

[0001] This utility model relates to the field of river dredging technology, and in particular to an underwater river dredging device with self-cleaning function. Background Technology

[0002] Because silt easily settles in river channels, and this silt contains residual impurities, if it is not cleaned in a timely manner, it can easily become putrid and affect the water quality of the river. Furthermore, when a large amount of silt accumulates, it can cause drainage difficulties, and in severe cases, lead to flooding. Therefore, it is necessary to regularly clean the silt in river channels to achieve the desired dredging effect.

[0003] Existing river silt removal equipment generally lacks effective self-cleaning capabilities. During continuous operation, viscous silt easily adheres to the surfaces of critical components, such as excavator buckets, conveying pipes, and transfer interfaces. This adhesion not only increases operating resistance and energy consumption but can also clog discharge channels, leading to frequent downtime and requiring significant manpower for cleaning and maintenance. The continuous accumulation of silt can interfere with the normal operation of core mechanical components, directly disrupting their continuous working cycle and ultimately forcing the entire dredging process to halt. Therefore, existing equipment struggles to guarantee efficient, stable, and sustained automated silt removal operations in river channels.

[0004] To address the aforementioned problems, this utility model proposes an underwater dredging device for rivers with a self-cleaning function. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a river underwater dredging device with self-cleaning function.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a river underwater dredging device with self-cleaning function, including a mobile vehicle 1, on which a support column 2 is fixedly installed. A T-shaped groove 14 is formed on the side wall of the support column 2, and a hydraulic lifting rod 15 is fixedly installed on the bottom side inside the T-shaped groove 14. A T-shaped slider 3 is fixedly installed on the telescopic end of the hydraulic lifting rod 15, and the T-shaped slider 3 slides within the T-shaped groove 14. This structure allows the T-shaped slider 3 to be raised and lowered inside the support column 2. The hydraulic lifting rod 15 controls the raising and lowering movement of the T-shaped slider 3, thereby driving the fixed sleeve 4, motor 5, connecting block 6, fixed pipe 7, moving rod 8, and bucket 9 to move synchronously, facilitating adjustment of the overall working height of the equipment.

[0019] A fixed sleeve 4 is fixedly installed on the side wall of the T-shaped slider 3. A motor 5 is fixedly installed inside the fixed sleeve 4. A connecting block 6 is fixedly installed on the output shaft of the motor 5. Multiple fixed tubes 7 are evenly fixedly installed around the axis on the outer wall of the connecting block 6. A moving rod 8 is slidably installed on the upper limit of the fixed tube 7. Multiple limiting holes 18 are evenly opened on the side wall of the moving rod 8 along the axial direction. Limiting bolts 19 are slidably installed on the fixed tube 7, and the limiting holes 18 and the limiting bolts 19 are engaged. By adjusting the limiting bolts 19, the limiting bolts 19 can be inserted into the limiting holes 18 at different positions, thereby adjusting the docking position of the moving rod 8 and the fixed tube 7, further adjusting the dredging depth of the bucket 9, and enhancing the adaptability of the equipment to different water depth conditions.

[0020] A bucket 9 is fixedly installed at the end of the movable rod 8 away from the fixed pipe 7. The bucket 9 has evenly spaced filter holes, allowing water to be discharged after the sludge is excavated, achieving initial separation of mud and water. An inclined surface 10 is provided on the side of the bucket 9 connected to the movable rod 8, with the lower end of the inclined surface 10 close to the receiving bucket 11. A mud discharge port 12 is provided on the side of the bucket 9 corresponding to the receiving bucket 11. A baffle 13 is rotatably installed inside the mud discharge port 12, and torsion springs are installed at the rotatable connection between the baffle 13 and the mud discharge port 12.

[0021] In the aforementioned mechanism, the preload torque of the torsion spring is only used to maintain the baffle 13 in its normally closed state. This allows only a small external force to overcome the torque and thus push the baffle 13 open.

[0022] When the bucket 9 rotates to the top of the fixed sleeve 4, the sludge is discharged to the discharge port 12 through the inclined plane 10, and the baffle 13 is pushed to open, and then falls into the receiving bucket 11, realizing the automatic dumping of sludge.

[0023] A receiving hopper 11 is fixedly installed on the upper side of the outer wall of the fixed sleeve 4. Both sides of the T-shaped slider 3 are bolted with buckle plates 16, and each buckle plate 16 has a sludge discharge pipe 17 locked inside. One end of the sludge discharge pipe 17 extends into the receiving hopper 11 and communicates with its interior; the other end of the sludge discharge pipe 17 points vertically downwards towards the ground. The sludge in the receiving hopper 11 can be discharged through the sludge discharge pipe 17, achieving directional transport and collection of the sludge.

[0024] The motor 5 drives the connecting block 6 to rotate, which in turn drives the bucket 9 to rotate and enter the river channel to dredge silt. The silt is then lifted and dumped into the receiving bucket 11, and finally discharged through the sludge discharge pipe 17, thus enabling continuous silt removal.

[0025] Working principle: The extension and retraction of the hydraulic lifting rod 15 controls the vertical lifting and lowering of the T-shaped slider 3 within the T-shaped groove 14, thereby driving the fixed sleeve 4, motor 5, connecting block 6, fixed pipe 7, moving rod 8, and bucket 9 to rise and fall synchronously as a whole, achieving the initial adjustment of the equipment's working position. Based on this, by adjusting the insertion position of the limit bolt 19 in different height limit holes 18, the length of the moving rod 8 extending out of the fixed pipe 7 can be flexibly changed, thereby precisely adjusting the dredging depth of the bucket 9 underwater, making it adaptable to different river silt conditions.

[0026] After preparation, the motor 5 is started to drive the connecting block 6 to rotate at a constant speed. The connecting block 6 then drives multiple circumferentially distributed fixed pipes 7 and moving rods 8 to perform circular motion, thereby forcing the bucket 9 to rotate along a certain trajectory and cut into the silt layer at the bottom of the river, completing the dredging operation. After the bucket 9 scoops up the silt, the filter holes evenly distributed on its wall can filter out most of the water during the lifting process, achieving preliminary separation of mud and water. When the bucket 9 carrying the silt moves with the rotating mechanism to above the fixed sleeve 4, that is, close to the receiving bucket 11, the inclined surface 10 on the inner side of the bucket 9 uses its tilt... The structure guides the silt to gather and slide towards the lower discharge port 12. The accumulated silt exerts pressure on the baffle 13 and overcomes the torque of the torsion spring, causing it to open outward. The silt then flows smoothly through the discharge port 12 into the receiving hopper 11 below it. Finally, the silt entering the receiving hopper 11 flows into the discharge pipe 17 connected to it under the action of gravity, and is discharged to the designated collection point through the vertically downward pipe opening pointing to the ground. This cycle repeats continuously, forming a set of automated workflows for dredging, filtering, and discharging silt, achieving efficient and continuous cleaning of river silt.

[0027] In another embodiment, such as Figure 5 As shown, the moving rod 8 and the bucket 9 are rotatably connected via a universal joint 23, thus providing the bucket 9 with multi-degree-of-freedom deflection capability. An elliptical guide ring 20 is fixedly installed on the side wall of the receiving bucket 11. The upper and lower halves of the elliptical guide ring 20 have different inner diameters, specifically, the upper half has a smaller inner diameter and the lower half has a larger inner diameter, thus forming a gradually changing guide profile inside. A continuous slide rail 21 is also provided on the inner wall of the elliptical guide ring 20. A limiting slider is slidably mounted in the slide rail 21, which can move smoothly along the slide rail 21. A connecting plate 22 is fixedly connected to the limiting slider, and the other end of the connecting plate 22 is fixedly connected to the bottom side of the bucket 9, thus binding the movement of the bucket 9 and the elliptical guide ring 20 together.

[0028] The working process is as follows: When the moving rod 8 drives the bucket 9 to move upward and gradually enters the upper half of the elliptical guide ring 20, as the inner diameter of this section gradually decreases, the slide rail 21 exerts radial compression and guiding action on the limiting slider, forcing the connecting plate 22 to drive the bucket 9 to rotate around the universal joint 23, causing the opening of the bucket 9 to gradually tilt towards the inside of the receiving bucket 11; as the position of the bucket 9 continues to rise, it further deflects under the constraint of the upper half of the elliptical guide ring 20, eventually forming a significant unloading angle, ensuring that the silt accumulated in the bucket 9 can smoothly slide down due to its own weight and be completely discharged into the receiving bucket 11. By realizing the automatic control of the attitude of the bucket 9 through the geometric constraints of the mechanical structure itself, not only is the reliability of unloading improved, but the use of additional power components is also avoided, making the overall structure more compact and reasonable.

[0029] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
