Description

Technical Field

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

[0002] Hydraulic engineering projects are engineering works constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. The construction of hydraulic engineering projects controls water flow, prevents floods, and regulates and distributes water to meet the water needs of people's lives and production. Hydraulic engineering projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives. In hydraulic engineering, silt accumulation has always been a key concern, as silt accumulation can reduce the functionality of hydraulic structures and even affect their structural strength, creating safety hazards.

[0003] Current water conservancy engineering dredging equipment uses mud pumps to suck out silt, which simultaneously brings a large amount of water into the silt tank. Workers need to clean the silt tank in a timely manner to separate the pumped-out silt and water, which not only reduces the storage space of the silt tank but also increases the workload of the mud pump, thereby reducing work efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dredging device for water conservancy projects. It has the advantages of reducing the water intake of the mud pump and filtering and cleaning excess water inside the sludge tank. This solves the problem that when the mud pump sucks out the sludge, it also carries a large amount of water into the sludge tank, reducing the storage space of the sludge tank and increasing the workload of the mud pump, thereby reducing work efficiency.

[0005] This utility model provides the following technical solution: a dredging device for water conservancy projects, including a dredging vehicle. A driver's cab is located at the rear end of the upper surface of the dredging vehicle. A sludge tank is fixedly installed at the center of the front end of the upper surface of the dredging vehicle. Fixed arms are fixedly installed on the left and right sides of the front end of the upper surface of the dredging vehicle. A connecting block is movably connected to the output end of the fixed arm. A dredging frame is fixedly connected to the end of the connecting block away from the fixed arm. A first motor housing is fixedly installed at the left end of the dredging frame. A first motor is fixedly installed in the first motor housing. A spiral auger is fixedly connected to the output shaft of the first motor. A connecting cylinder is fixedly installed at the right end of the dredging frame. A connecting pipe is fixedly installed at the right end of the connecting cylinder. The end of the connecting pipe away from the connecting cylinder is connected to the sludge tank. A first mud pump is located at the end of the connecting pipe near the connecting cylinder. A second mud pump is located at the end of the connecting pipe near the sludge tank. A sludge discharge pipe is fixedly installed at the bottom end of the sludge tank. A drain outlet is located at the bottom left side of the circumferential surface of the sludge tank.

[0006] Furthermore, a shovel plate is provided at the lower front end of the dredging frame, which makes it easier to insert the dredging frame into the silt.

[0007] Furthermore, a connecting ring is fixedly installed on the upper inner wall of the sludge tank, and a filter cylinder is movably connected to the bottom end of the connecting ring. The lower end of the filter cylinder is funnel-shaped, and the bottom end of the filter cylinder penetrates the bottom wall of the sludge tank. A second motor is fixedly installed at the middle of the top of the sludge tank, and a rotating rod is fixedly installed on the output shaft of the second motor. A fixed rod is fixedly connected to the middle of the circumferential surface of the rotating rod, and the fixed rod is fixedly installed on the inner wall of the filter cylinder. A spiral blade is provided on the circumferential surface of the bottom end of the rotating rod, and the spiral blade is movably installed inside the upper end of the sludge discharge pipe. The bottom outlet of the filter cylinder is located in the sludge discharge pipe. When sludge is transported to the filter cylinder in the sludge tank through the connecting pipe, the second motor is started, and the second motor rotates the filter cylinder through the fixed rod fixedly installed on the rotating rod. This allows the remaining water in the filter cylinder to be discharged into the space between the sludge tank and the filter cylinder under the action of centrifugal force, and then discharged from the drain outlet. At the same time, the sludge inside the filter cylinder is transported to the sludge discharge pipe for discharge through the spiral blade.

[0008] Furthermore, the diameter of the auger is the same as the height of the shovel plate, and the right end of the auger passes through the right side of the shovel plate and is movably installed inside the connecting cylinder. This allows the auger to more stably transport the silt in the shovel plate to the connecting cylinder, while also reducing the amount of water entering the connecting cylinder from between the shovel plate and the auger.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. During the dredging process, the hydraulic rod under the fixed arm rotates the dredging frame around the connecting block, adjusting it to the appropriate position. The dredging vehicle then moves forward with the dredging frame, pushing the sludge into the frame. The first motor is then activated, rotating the auger to transport the sludge accumulated in the dredging frame to the connecting cylinder. Simultaneously, the first and second mud pumps are activated to transport the sludge through the connecting pipe to the sludge tank for collection. The second motor, via a fixed rod on the rotating rod, rotates the filter cylinder, causing centrifugal motion of the sludge and remaining water in the filter cylinder. The remaining water, under centrifugal force, flows from the filter cylinder into the space between the sludge tank and the filter cylinder. Once the tank is full, the excess water is discharged to the outside through the drain outlet, improving work efficiency. After collection, the sludge inside the filter cylinder is transported to the discharge pipe through the spiral blades for discharge, reducing the water content of the sludge in the sludge tank.

[0011] 2. By making the diameter of the auger consistent with the height of the shovel plate, the gap between the auger and the shovel plate can be reduced, thereby allowing the auger to more stably transport the silt in the shovel plate to the connecting cylinder, while also reducing the amount of external water entering the connecting cylinder from between the shovel plate and the auger.

A first motor housing 8 is fixedly installed on the left end of the dredging frame 6. A first motor 9 is fixedly installed in the first motor housing 8. A spiral auger 10 is fixedly connected to the output shaft of the first motor 9. A connecting cylinder 11 is fixedly installed on the right end of the dredging frame 6. A connecting pipe 12 is fixedly installed on the right end of the connecting cylinder 11. The end of the connecting pipe 12 away from the connecting cylinder 11 is connected to the sludge tank 3. A first mud pump 13 is located at the end of the connecting pipe 12 near the connecting cylinder 11, and a second mud pump 14 is located at the end of the connecting pipe 12 near the sludge tank 3. A sludge discharge pipe 21 is fixedly installed at the bottom of the sludge tank 3. A drain outlet 22 is provided at the bottom left side of the circumferential surface of the sludge tank 3. During the sludge removal process, the sludge removal vehicle 1 drives the sludge removal frame 6 to rotate around the connecting block 5 through the hydraulic rod under the fixed arm 4, thereby adjusting the sludge removal frame 6 to a suitable position. Then, the sludge removal vehicle 1 moves forward with the sludge removal frame 6. During the movement, the sludge removal vehicle 1 pushes the sludge into the sludge removal frame 6. Then, the first motor 9 is started, which drives the spiral auger 10 to rotate, thereby driving the sludge accumulated in the sludge removal frame 6 into the connecting cylinder 11. At the same time, the first mud pump 13 and the second mud pump 14 are started, allowing the first mud pump 13 and the second mud pump 14 to transport the sludge to the sludge tank 3 for collection through the connecting pipe 12. After collection, the sludge in the filter cylinder 16 is discharged from the sludge discharge pipe 21, and the excess water is discharged to the outside from the drain outlet 22.

[0019] In this embodiment, a shovel plate 7 is provided at the lower front end of the dredging frame 6; by providing a shovel plate 7 at the lower front end of the dredging frame 6, the dredging frame 6 can be inserted into the silt more easily, thereby collecting and transporting the silt.

[0020] In this embodiment, a connecting ring 15 is fixedly installed on the upper inner wall of the sludge tank 3. A filter cylinder 16 is movably connected to the bottom end of the connecting ring 15. The lower end of the filter cylinder 16 is funnel-shaped, and the bottom end of the filter cylinder 16 penetrates the bottom wall of the sludge tank 3. A second motor 17 is fixedly installed at the middle of the top of the sludge tank 3. A rotating rod 18 is fixedly installed on the output shaft of the second motor 17. A fixing rod 19 is fixedly connected to the end of the rotating rod 18 away from the second motor 17. The fixing rod 19 is fixedly installed on the inner wall of the filter cylinder 16. A spiral blade 20 is provided on the circumferential surface of the bottom end of the rotating rod 18. The spiral blade 20 is movably installed inside the upper end of the sludge discharge pipe 21. The bottom outlet of the filter cylinder 16 is located in the sludge discharge pipe 21. When the sludge is transported to the filter cylinder 16 in the sludge tank 3 through the connecting pipe 12, the second motor 17 is started, and the second motor 17 rotates the filter cylinder 16 through the fixed rod 19 fixedly installed on the rotating rod 18. Then, the remaining water is discharged from the filter cylinder 16 into the space between the sludge tank 3 and the filter cylinder 16 under the action of centrifugal force. After the space is full, the excess water is discharged to the outside through the drain outlet 22, thereby reducing the water content of the sludge in the sludge tank 3. At the same time, during the rotation of the filter cylinder 16, the second motor 17 rotates the spiral blade 20 through the rotating rod 18, thereby transporting the sludge inside the filter cylinder 16 to the sludge discharge pipe 21 for discharge, thereby improving working efficiency.

[0021] In this embodiment, the diameter of the auger 10 is the same as the height of the shovel plate 7, and the right end of the auger 10 is movably installed inside the connecting cylinder 11 through the right side of the shovel plate 7. Making the diameter of the auger 10 the same as the height of the shovel plate 7 allows the auger 10 to more stably transport the sludge in the shovel plate 7 to the connecting cylinder 11. At the same time, allowing the right end of the auger 10 to movably install inside the connecting cylinder 11 through the right side of the shovel plate 7 reduces the amount of water entering the connecting cylinder 11 from between the shovel plate 7 and the auger 10.

[0022] Working principle: During the dredging process, the operator drives the dredging vehicle 1 to adjust the position of the dredging frame 6 using the fixed arm 4. The dredging vehicle 1 then moves forward with the dredging frame 6, pushing the sludge into the dredging frame 6. The first motor 9 is then started, causing the auger 10 to rotate, thus moving the sludge accumulated in the dredging frame 6 into the connecting cylinder 11. Simultaneously, the first mud pump 13 and the second mud pump 14 are started, allowing them to transport the sludge to the sludge tank 3 for collection via the connecting pipe 12. When the water is transported to the filter cylinder 16 in the sludge tank 3 through the connecting pipe 12, the second motor 17 is started. The second motor 17 drives the filter cylinder 16 to rotate around the connecting ring 15 through the fixed rod 19 fixedly installed on the rotating rod 18. Then, the remaining water is discharged from the filter cylinder 16 into the space between the sludge tank 3 and the filter cylinder 16 under the action of centrifugal force. After the space is full, the excess water is discharged to the outside through the drain outlet 22 to reduce the water content of the sludge in the sludge tank 3. Then, the sludge inside the filter cylinder 16 is transported to the sludge discharge pipe 21 through the spiral blade 20 for discharge, thereby improving working efficiency.
