Description

Technical Field

[0001] This utility model relates to the field of waterway dredging technology, and in particular to a water conservancy project waterway dredging device. Background Technology

[0002] In the process of water conservancy construction, dredging and management of river channels are crucial. Dredging and management not only affect the ecological operation of the river channel, but also the irrigation level. By carrying out dredging operations, we can reduce the problem of river channel congestion and improve the water conveyance capacity of the river channel.

[0003] Patent CN222878787U discloses a dredging device for water conservancy projects. In use, a stirring motor is installed on top of a fixed plate, with a shaft at its bottom that penetrates the fixed plate. Rotating blades are installed at the bottom of the shaft. The stirring motor and rotating blades disperse the silt and debris at the bottom of the water channel. A collection box is installed on top of the fixed plate, and a silt pump is installed on top of the collection box. An extraction pipe is installed on the side of the collection box, and a sewage pipe is installed outside the collection box. The silt deposited at the bottom of the water channel is extracted through the silt pump and the collection box. However, the above device has the following drawbacks: due to long-term contact with water flow, silt adheres to the sidewalls of the water channel. This silt may detach with the water flow and settle at the bottom of the water channel, or it may adhere to the sidewalls for a long time, causing the silt to gradually thicken, reducing the cross-sectional area of ​​the water channel and decreasing water flow efficiency.

[0004] Therefore, how to clean the silt on the sidewalls of the canal has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The side wall of the protective cover is also provided with a wire hole. The protective cover can reduce the exposed area of ​​the drive components. The bolts and wire holes are not shown in the figure.

[0054] The working principle of this utility model is as follows: Before dredging, the following preparatory work needs to be carried out: First, the dredging area of ​​the water channel is surveyed to determine the cross-sectional shape of the water channel ("U" shape or trapezoidal shape). According to the cross-sectional shape of the water channel, the setting method of the two scrapers 3 is adjusted (parallel setting or inclined setting). The distance between the two scrapers 3 is adjusted by the first connecting rod 10, the second connecting rod 11 and the second fastener of the connecting component, so that the scrapers 3 fit against the side wall of the water channel.

[0055] The device is placed above the water channel using specialized equipment such as a crane or hoist, with four wheels 25 spanning both sides of the channel. The scraper 3, connecting components, sludge breaking components, and filter frame 20 are all located inside the water channel. A section of the water channel is cleared in advance to accommodate the scraper 3, connecting components, sludge breaking components, and filter frame 20.

[0056] Then, the second motor 21 is started. The output shaft of the second motor 21 drives the stirring shaft 22 to rotate. The stirring shaft 22 drives the stirring rod 23 to rotate. The stirring rod 23 crushes the silt at the bottom of the canal. After that, the first motor 17 and the silt pump 4 are started. The output shaft of the first motor 17 drives the screw 16 to rotate. The screw 16 drives the slider 18 to move back and forth along the screw 16. The slider 18 drives the suction pipe 7 to move repeatedly along the slide groove 2 through the fixed ring 19. At the same time, the silt pump 4 starts to work. The crushed silt in the canal enters the suction pipe 7 through the filter grid of the filter frame 20. It is then transported to the sludge inlet pipe 5 through the suction pipe 7, and then enters the silt pump 4. Finally, it is transported to the silt transportation equipment through the sludge outlet pipe 6.

[0057] During the sludge suction process, the staff pushes the push rod 26 on the upper end of the base plate 1 to move the device to the position of the water channel. At the same time, the scraper 3 moves with the device to scrape the sludge on the side wall of the water channel toward the suction pipe 7. The stirring rod 23 breaks up the sludge scraped off by the scraper 3 and the accumulated sludge.
