Description

Technical Field

[0001] This utility model relates to the field of river management, specifically to a dredging device. Background Technology

[0002] In river management and maintenance projects, dredging is a crucial step, aiming to remove deposited silt, garbage, and other debris to restore the river's flood control capacity, improve water quality, and ensure ecological balance. Traditional river dredging methods typically employ excavators or bucket boats, using robotic arms to dredge silt from the riverbed and transport it to the banks or to transport vehicles. However, this approach has significant limitations, resulting in low dredging efficiency and failing to meet the demands of modern river management.

[0003] First, traditional excavators are inefficient at dredging. Because excavators have limited capacity per operation and require frequent movement and repositioning, the amount of silt processed per unit of time is relatively small. Furthermore, the viscosity and high water content of the silt make it prone to sticking and dripping during excavation and transport, further reducing work efficiency.

[0004] Secondly, traditional methods have high requirements for the construction environment. Excavators usually need to operate on riverbanks or slopes, and due to limitations in terrain and load-bearing capacity, they are difficult to work flexibly in narrow or soft river areas. Furthermore, the frequent movement of large machinery can damage the riverbank structure, increasing additional repair costs.

[0005] Furthermore, traditional dredging methods are neither economical nor environmentally friendly. Excavator operations typically require multiple transport vehicles to move the sludge, which not only increases labor and equipment costs but also easily causes secondary pollution during transportation. The high water content of the sludge also makes subsequent treatment (such as dehydration and solidification) more difficult, further increasing the overall treatment cost.

[0006] In summary, traditional excavator-based dredging methods suffer from low efficiency, poor adaptability, high costs, and environmental hazards. Therefore, there is an urgent need to develop a highly efficient, environmentally friendly, and adaptable river dredging device to improve the automation of dredging operations, reduce construction costs, and minimize environmental impact. Utility Model Content

[0007] The purpose of this invention is to provide a sludge removal device to solve the problem of low efficiency in existing sludge removal methods.

The bucket has a sludge-gathering space, and the bottom and one side of the bucket are open. The drum is rotatably mounted on the side of the bucket opposite to the opening. The sludge pump is mounted on the top of the bucket, and the top of the bucket has a sludge hole. The sludge pump is connected to the sludge-gathering space through the sludge hole. One end of the pipeline is connected to the sludge pump, and the other end of the pipeline is connected to the outside.

[0009] Beneficial effects: The synergistic design of the bucket, sludge pump, pipeline, and drum enables highly efficient sludge collection and transportation. The bottom and side openings of the bucket facilitate sludge entry, the drum enhances the flexibility and adaptability of the unit, and the sludge pump quickly discharges sludge through the pipeline, making it particularly suitable for operations in narrow or complex environments.

[0010] Preferably, the bucket is trapezoidal in shape, and the length of the bucket on the side closer to the drum is shorter than the length on the side farther from the drum.

[0011] Beneficial effects: The trapezoidal bucket design optimizes the angle at which it cuts into the silt, reduces resistance, and improves collection efficiency.

[0012] Preferably, hollow sections are provided on both sides of the bucket, and the hollow sections are in the shape of a triangular prism.

[0013] Beneficial effects: The hollow triangular prism shape reduces weight and energy consumption while ensuring structural strength.

[0014] Preferably, the mud-gathering space is configured to gradually narrow inward from the side with the opening.

[0015] Beneficial effects: The inward narrowing design of the sludge collection space effectively concentrates the sludge, prevents it from scattering, and improves pumping efficiency.

[0016] Preferably, the hollow portion has an upward inclined surface on the side away from the roller.

[0017] Beneficial effects: The inclined plane further optimizes the sludge flow path, reduces accumulation, and ensures that the sludge enters the pumping area smoothly.

[0018] Preferably, extension plates are provided at both ends of the bucket away from the opening, and the roller is rotatably disposed between the extension plates on both sides.

[0019] Beneficial effects: The extended plate structure enhances the installation stability of the roller, ensuring smooth operation and easy maintenance.

[0020] Preferably, a connector is provided on the top of the bucket, and a through hole is provided on the connector.

[0021] Beneficial effects: The connector design allows the device to be flexibly adapted to different external devices.

[0024] Figure 1 A schematic diagram of the sludge removal device provided in this embodiment of the utility model; Figure 2 This is a structural schematic diagram of a sludge removal device from another perspective, provided as an embodiment of the present invention. Detailed Implementation

[0025] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: bucket 1, sludge pump 2, pipeline 3, drum 4, sludge accumulation space 5, sludge hole 6, hollow part 7, inclined surface 8, extension plate 9, connector 10, and through hole 11.

[0026] As attached Figure 1-2 As shown in the figure, this embodiment demonstrates a sludge removal device, which is particularly suitable for sludge removal operations in water bodies such as rivers, lakes, and ponds. Through the coordinated action of the bucket 1 and the sludge pump 2, this device can efficiently extract sludge from the bottom of the water and transport it to a designated location. It has the advantages of simple structure, convenient operation, and high cleaning efficiency.

[0027] The sludge removal device in this embodiment mainly includes a bucket 1, a sludge pump 2, a pipeline 3, and a drum 4. The bucket 1, as the main sludge collection component, has an internal sludge-gathering space 5. The bottom and one side of the bucket 1 are open to facilitate sludge entry into the sludge-gathering space 5. A sludge hole 6 is provided at the top of the bucket 1, and the sludge pump 2 is installed at the top of the bucket 1 and communicates with the sludge-gathering space 5 through the sludge hole 6. The function of the sludge pump 2 is to extract the sludge from the sludge-gathering space 5 and transport it to external processing equipment or a storage site through the pipeline 3. One end of the pipeline 3 is connected to the sludge pump 2, and the other end extends to the outside, allowing connection to sludge separation equipment, transport vehicles, or temporary storage ponds as needed.

[0028] The roller 4 is located on the side of the bucket 1 facing away from the opening and is rotatably mounted on the bucket 1. The function of the roller 4 is to reduce the frictional resistance of the bucket 1 when it moves on the seabed, and at the same time help the bucket 1 to better adapt to the uneven seabed terrain, thereby improving the efficiency of silt collection.

[0029] Specifically, the bucket 1 has a trapezoidal shape, with the side closer to the drum 4 being shorter and the side closer to the opening being longer. This design allows the bucket 1 to more effectively collect silt during movement, while reducing the scouring effect of water flow on the silt. The bucket 1 has hollow sections 7 on both sides inside, and these hollow sections 7 are triangular prisms in shape. This structure reduces the overall weight of the bucket 1 while maintaining its structural strength, facilitating underwater operation.

[0030] The mud-gathering space 5 is designed to gradually narrow inward from the opening side, allowing the silt to naturally concentrate towards the silt hole 6 after entering the bucket 1, facilitating efficient extraction by the silt pump 2. The hollow part 7 has an upward inclined surface 8 on the side away from the roller 4. This design helps the bucket 1 move on the bottom of the riverbed and reduces the friction between the bottom of the bucket 1 and the bottom of the riverbed.

[0031] The bucket 1 has extension plates 9 at both ends away from the opening. The roller 4 is mounted between the extension plates 9 on both sides via bearings or a shaft, allowing it to rotate freely. This structure makes the bucket 1 move more smoothly underwater, reduces resistance, and improves work efficiency.

[0032] The top of the bucket 1 is equipped with a connector 10, which has a through hole 11 for connecting lifting equipment or traction devices, facilitating the installation, disassembly, and transportation of the bucket 1. Furthermore, the bucket 1 is made of stainless steel, possessing excellent corrosion resistance and wear resistance, making it suitable for long-term underwater operations.

[0033] In actual operation, this sludge removal device can be moved underwater by dragging the bucket 1 using traction equipment (such as a ship or excavator). The open side of the bucket 1 contacts the sludge layer, and as the device moves, the sludge is collected by the bucket 1 and enters the sludge collection space 5. After the sludge pump 2 is started, it sucks the sludge from the sludge collection space 5 through the sludge hole 6 and transports it to the outside through the pipeline 3. The rotation of the drum 4 allows the bucket 1 to adapt to different underwater terrains, ensuring the continuity and efficiency of sludge collection.

[0034] This device is suitable for dredging operations in various water bodies, such as river dredging, lake management, and pond cleaning. Its modular design allows for easy adjustment of the bucket size 1 and sludge pump power 2 according to different operational needs, providing strong adaptability. Furthermore, the device can be integrated with an automated control system to achieve remote operation, further improving operational safety and efficiency.

[0035] In summary, the sludge removal device of the present invention achieves efficient and stable sludge removal function by optimizing the structure of the bucket 1 and rationally arranging the sludge pump 2 and the drum 4, and has broad market application prospects.
