Description

Technical Field

[0001] This utility model relates to the field of dredging technology, specifically to a river dredging and desilting device for water conservancy construction. Background Technology

[0002] River dredging and desilting refers to the systematic cleaning and clearing of river channels, aiming to remove silt, debris, and sediment to restore the normal flow capacity of the river. Through specialized machinery and manual labor, the bottom and sides of the river are thoroughly excavated and cleaned to ensure smooth water flow and effectively prevent blockages and rising water levels.

[0003] In river dredging operations, dredging equipment is typically equipped with filter plates to block large amounts of external impurities such as stones, preventing them from entering subsequent pipes and equipment. However, after prolonged use, a large amount of impurities easily accumulates on the lower surface of the filter plates. This not only reduces filtration efficiency but can also lead to filter plate blockage, thus affecting the normal operation of the entire dredging equipment. Although some dredging equipment is equipped with brush plates to clean the attached impurities on the filter plates, these brush plates will be damaged during long-term use due to friction, corrosion, and aging from the impurities. Therefore, disassembling and maintaining the brush plates is essential. However, existing equipment presents inconveniences in brush plate replacement and maintenance, requiring significant time and effort for disassembly and installation. This results in excessively long interruptions in dredging operations, severely impacting work efficiency. Utility Model Content

[0004] This utility model provides a river dredging and desilting device for water conservancy construction, which can easily remove impurities attached to the filter plate and can conveniently disassemble the brush plate for easy maintenance.

[0023] Reference Figures 1 to 4 This utility model discloses a river dredging and desilting device for water conservancy construction, comprising a main body 1. A through hole 1 is formed on the upper inner surface of the main body 1, and a rotating rod 12 is rotatably connected within the through hole 1. A sludge pump 5 is fixedly connected to the upper inner surface of the main body 1. A second through hole is formed on the upper inner surface of the main body 1 near the sludge pump 5. A conveying pipe 6 is fixedly connected to the input end of the sludge pump 5. The conveying pipe 6 passes through the second through hole and is fixedly connected to a connecting seat 8. A fixing groove 18 is formed on the inner arc surface of the connecting seat 8. A filter plate 19 is fixedly connected to the lower surface of the fixing groove 18. A third through hole is formed on the upper surface of the filter plate 19 near its center. The device allows for rotation... A fixing seat 14 is fixedly connected to three through holes on the lower surface of rod 12. A connecting groove 17 is formed on the side surface of the fixing seat 14, and an installation groove 16 is formed on the side surface of the fixing seat 14 away from the connecting groove 17. A sliding hole is formed on the upper surface of the installation groove 16 near the connecting groove 17, and a plug 20 is slidably connected in the sliding hole. A threaded rod 22 is rotatably connected to the inner surface of the installation groove 16, and a moving block 21 is slidably connected to the lower surface of the installation groove 16. A threaded hole is formed on the side surface of the moving block 21 near the threaded rod 22. A connecting seat 9 is provided in the connecting groove 17, and the threaded hole and threaded rod 22 engage. During installation, the connecting seat 9 is inserted into the connecting groove 17, the limiting hole 10 is aligned with the sliding hole, and then it is rotated clockwise. At this time, the rotating component 15 drives the threaded rod 22 to rotate synchronously, causing the moving block 21 to move towards the plug 20. The most inclined surface of the moving block 21 presses tightly against the bottom end of the plug 20, pushing the plug 20 to slide in the sliding hole. Finally, the insertion post 20 passes through the limiting hole 10 and abuts against the inner wall of the connecting groove 17, thereby achieving a stable limiting and fixing of the connecting groove 17.

[0024] One end of the threaded rod 22 is fixedly connected to the side surface of the rotating part 15. A mounting base 2 is fixedly connected to the upper inner surface of the main body 1 near the through hole. A fixing plate is fixedly connected to the side surface of the fixing base 14 near the mounting groove 16. The rotating part 15 is rotatably connected to the side surface of the fixing plate. Several braking holes are opened on the side surface of the fixing plate near the rotating part 15. Threaded holes are opened on the side surface of the rotating part 15 near the braking holes. A limit hole 10 is opened on the upper surface of the connecting base 9 near the insertion post 20. A brush plate 13 is fixedly connected to the side surface of the connecting base 9. After installation, to prevent the rotating part 15 from rotating due to external forces, an external bolt can be inserted into the threaded hole and then rotated until one end of the bolt is embedded in any of the braking holes. Through the cooperation of the external bolt and the threaded hole, thread locking is achieved, thereby effectively limiting and fixing the position of the rotating part 15.

[0025] The side surface of the main body 1 is fixedly connected to the storage chamber 4. A float plate 11 is fixedly connected to the lower surface of the main body 1. A connecting pipe 7 is fixedly connected to the output end of the mud pump 5. The side surface of the connecting pipe 7 passes through the storage chamber 4 fixedly connected to the main body 1. A motor 3 is fixedly connected to the upper surface of the mounting base 2. The output end of the motor 3 passes through the mounting base 2 and is fixedly connected to the upper surface of the rotating rod 12.

[0026] Working Principle: During use, the sludge pump 5 is started, and the sludge is pumped out of the river channel through the cooperation of the conveying pipe 6 and the connecting seat 8. When the sludge enters, the filter plate 19 blocks a large amount of impurities, and then the connecting pipe 7 transports the sludge to the storage bin 4 for storage. After long-term use, impurities easily adhere to the lower surface of the filter plate 19, affecting its performance. At this time, the motor 3 can be started to drive the fixed seat 14 to rotate, which drives the brush plate 13 to clean the impurities. During long-term dredging operations, the brush plate 13 is prone to wear, damage or aging, so it needs to be disassembled for maintenance. By unscrewing the fixing bolts in the threaded hole and the brake hole, the rotating part 15 is rotated in the opposite direction, so that the moving block 21 moves closer to the fixed plate, and its inclined surface disengages from the bottom end of the insert post 20. The insert post 20 slides in the sliding hole under the action of gravity, and one end disengages from the limiting hole 10. Then the connecting seat 9 can be removed from the connecting groove 17 to perform maintenance on the brush plate 13.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
