Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and river channels, and more specifically, to a water conservancy and river channel dredging device. Background Art

[0002] The route through which river water flows usually refers to navigable waterways. According to the river grade classification method, first- and second-level rivers are mostly large rivers that span two or several provinces, and have a significant impact on the overall national economy and social development. Therefore, such rivers must be recognized by the Ministry of Water Resources; most of the third-level rivers affect one province or neighboring provinces. Their importance is slightly lower than that of first- and second-level rivers, but they also have a considerable impact on the regional national economy. In order to make the standards between provinces roughly consistent and facilitate the classification of cross-provincial rivers, such rivers should be authorized by the Ministry of Water Resources to consult with the water conservancy (hydropower) departments (bureaus) of the provinces (autonomous regions, municipalities directly under the central government) where they are located, and then report to the Ministry of Water Resources for recognition; fourth- and fifth-level rivers are recognized by the water conservancy (hydropower) departments (bureaus) of each province (autonomous region, municipality directly under the central government).

[0003] According to the patent document: CN113216088A, a river channel silt removal device for water conservancy projects is disclosed, including a mobile frame, a driving unit, a trenching unit, and a sludge shoveling unit; the trenching unit for digging a sludge landfill groove is installed at the front end of the mobile frame, and the sludge shoveling unit is installed on the driving unit. The mobile frames on both sides of the driving unit are also provided with sludge boxes, and the sludge boxes are located below the discharge end of the sludge shoveling unit. A material leakage port is opened at the bottom of the sludge box, and the material leakage port is located above the trench opened by the trenching unit. The present application uses the sludge shoveling unit to shovel the sludge into the sludge box for storage, and uses the trenching assembly to dig trenches beside the river channel, and bury the sludge on the spot, which is convenient for rapid drying of the sludge and reduces the cost of transporting the sludge outward; the driving unit is set to drive the sludge shoveling unit to move to both sides of the mobile frame, so as to realize the countercurrent shoveling of the sludge in the river channel on both sides of the mobile frame, and has a wider range of applications;

[0004] In addition to hindering river navigation and causing a decline in shipping capacity, the most important harm of river siltation is that it reduces the river's flood discharge capacity, aggravates flood disasters, and increases flood control difficulties. After silt accumulates in the river for a long time, it will condense together to form a hard mud block, which further increases the difficulty of dredging. Existing dredging devices usually use silt extraction pipes to extract silt from the river. Since silt is relatively hard after condensation, during the silt extraction process, the silt extraction pipe is easily blocked by hard silt blocks, making it impossible to carry out silt extraction work, and the silt extraction pipe is easily broken in the silt, which increases the difficulty of dredging work.

[0005] In addition, when the silt is extracted by the silt pipe, it is usually extracted together with the water inside the river channel, resulting in a higher water content in the extracted silt, which causes inconvenience during transportation and handling. Summary of the invention

After the second motor 3110 is started, the second screw rod 317 is driven to rotate, thereby driving the push-pull plate transmission block 318 to drive the push-pull plate 315 to slide on the inner wall of the slide plate 313 according to the axial movement of the second screw rod 317, pushing the silt extraction device 4 to move horizontally.

[0040] like Fig.10As shown, the base 1 includes a base body 11, and the left and right sides of the front and rear sides of the base body 11 are rotatably connected with hubs 12 respectively, and the left and right sides of the base body 11 are fixedly connected with stabilizing frames 13 respectively. A silt extraction device control block 14 is fixedly connected to the middle of the top of the base body 11, and the front side of the silt extraction device control block 14 is fixedly connected to a silt extraction device connecting frame 15, and the front side of the silt extraction device connecting frame 15 is fixedly connected to the rear side of the connecting plate body 21. The left and right sides of the top of the base body 11 are respectively fixedly connected with sludge collecting bins 16, and the inner wall bottoms of the two sludge collecting bins 16 are fixedly connected with filter screens 17, and the front sides of the two sludge collecting bins 16 are fixedly connected. The two stabilizing frames 13 are fixedly connected to one end of the silt extraction pipe 42 away from the silt extraction device connecting plate 41, and the opposite surfaces of the two stabilizing frames 13 are fixedly connected with drainage plates 111, and the tops of the two drainage plates 111 are respectively fixedly connected with vertical plates 110, and the tops of the two groups of vertical plates 110 are fixedly connected with purifiers 19, and the opposite surfaces of the two purifiers 19 are fixedly connected with water extraction pipes 18, and the opposite surfaces of the two water extraction pipes 18 are respectively fixedly connected to the opposite surfaces of the two sludge collection bins 16, and the bottom ends of the two water extraction pipes 18 are respectively fixedly connected to the tops of the two drainage plates 111 through the bottom of the purifier 19, and the front sides of the two drainage plates 111 are fixedly connected with drainage pipes 112;

[0041] When the silt is discharged into the silt collecting bin 16, it is filtered by the filter screen 17 to separate the silt from the water. When the water in the silt needs to be discharged, the purifier 19 is first started. After the purifier 19 is started, the silt water in the silt collecting bin 16 is pumped out through the pumping pipe 18. After the purification treatment of the purifier 19, the silt and the water are separated. The separated water is discharged into the drain plate 111 through the bottom of the purifier 19, and then discharged through the drain pipe 112, thereby achieving effective separation of silt and water and improving the silt treatment efficiency. At the same time, the purification effect of the purifier 19 can remove impurities and pollutants in the silt, ensuring that the discharged water quality meets environmental protection standards and protecting the safety and sanitation of the surrounding environment. In addition, in the process of cleaning river silt, the design of the wheel hub 12 allows the entire device to be easily moved to different positions for operation, thereby improving work efficiency. The stabilizing frame 13 enhances the stability of the entire device, ensuring that it is not prone to shaking or tipping during operation.

[0042] Working principle of the present invention: when it is necessary to clean the river silt, first move the base 1 to the place to be cleaned, the connecting plate 2 is at the top of the river, and then start the two lifting frame motors 32, so that the output end of the lifting frame motor 32 drives the conical teeth 33 to rotate and mesh with the second conical teeth 34 to rotate, because the screw rod 35 is fixedly connected to the inner wall of the second conical teeth 34, the rotation of the second conical teeth 34 drives the screw rod 35 to rotate, the screw rod 35 rotates to drive the transmission block 39 to move axially downward on the outer wall of the screw rod 35, and the transmission block 39 moves downward to drive the telescopic rod 38 to telescope downward and drive the lateral transmission link The connecting block 312 moves downward, thereby driving the silt extraction device 4 to move downward so that the silt drill 4315 reaches the silt surface, and then the fourth motor 4312 is started to drive the silt drill rod body 4313 to drive the silt drill 4315 to rotate and drill the silt. At the same time, the third motor 413 starts to drive the third screw rod 415 to rotate, and the outer wall of the third screw rod 415 outside the silt loosening rod transmission block 417 moves axially to drive the silt loosening rod connecting block 418 to move upward through the axial direction of the third screw rod 415. The silt loosening rod connecting block 418 moves upward to drive the inner sliding rod 4322 to move upward through the slot 4324 and the bottom of the connecting shaft 4314. The mud drill 4315 is connected, so that the breaking rod transmission rod housing 4321 is connected to the mud drill rod body 4313. Since the multiple breaking rod transmission rod sliding grooves 4323 opened on the inner wall of the inner sliding rod 4322 are connected to the breaking rod connecting rod 4332, the mud drill rod body 4313 drives the breaking rod transmission rod housing 4321 to rotate and drives the breaking rod body 4331 to rotate while rotating. The mud drill 4315 drills into the interior of the mud, and the breaking rod body 4331 rotates with the rotation of the mud drill rod body 4313, and the breaking fan 4334 at its bottom rotates at high speed to break the mud. The silt is effectively broken up and loosened due to the rotation of the breaking fan 4334 and the up and down movement of the breaking rod body 4331, making it easier to be extracted by the silt extraction pipe 42. The silt extraction pipe 42 extracts and transmits it to the silt collection bin 16. In addition, when the silt extraction device 4 needs to be operated to move horizontally after the extraction of an area is completed, the second motor 3110 is first started. After the second motor 3110 is started, the second screw rod 317 is driven to rotate, thereby driving the push-pull plate transmission block 318 to drive the push-pull plate 315 to slide on the inner wall of the slide plate 313 according to the axial movement of the second screw rod 317, pushing the silt extraction device 4 to move horizontally;

[0043] When the silt is discharged into the silt collecting bin 16, it is filtered by the filter screen 17 to separate the silt from the water. When the water in the silt needs to be discharged, the purifier 19 is first started. After the purifier 19 is started, the silt water in the silt collecting bin 16 is pumped out through the pumping pipe 18. After the purification treatment of the purifier 19, the silt and the water are separated. The separated water is discharged into the drain plate 111 through the bottom of the purifier 19, and then discharged through the drain pipe 112, thereby achieving effective separation of silt and water and improving the silt treatment efficiency. At the same time, the purification effect of the purifier 19 can remove impurities and pollutants in the silt, ensuring that the discharged water quality meets environmental protection standards and protecting the safety and sanitation of the surrounding environment. In addition, in the process of cleaning river silt, the design of the wheel hub 12 allows the entire device to be easily moved to different positions for operation, thereby improving work efficiency. The stabilizing frame 13 enhances the stability of the entire device, ensuring that it is not prone to shaking or tipping during operation.
