Description

Technical Field

[0001] This invention belongs to the field of river sludge treatment technology, specifically relating to an intelligent, efficient, and environmentally friendly dredging and in-situ remediation device for black and odorous river bottom sediment. Background Technology

[0002] Black and smelly rivers and canals refer to rivers or ditches that turn black and emit an odor due to excessive organic pollutants, nitrogen, phosphorus and other nutrients in the water body, which undergo anaerobic decomposition under hypoxic conditions, producing malodorous substances such as hydrogen sulfide and ammonia. This not only seriously affects the surrounding ecological environment, but also endangers the health of residents.

[0003] In the current field of black and odorous river sediment remediation, dredging and restoration work generally adopts a phased operation mode. First, specialized dredging equipment (dredging vessels) needs to be dispatched to the river. These vessels often only have a single dredging function, using mechanical excavation or suction (the hull is equipped with a mechanical arm that can lower the bucket or suction head to the bottom of the river) to remove the sediment to the shore or transport it to a designated location. After the dredging operation is completed, the dredging equipment needs to be moved out of the river before restoration equipment is dispatched. The restoration equipment must first level the dredged riverbed before restoration materials can be laid. It is evident that the repeated entry and exit of equipment throughout the process not only consumes a significant amount of transportation and scheduling time, but also results in a lengthy dredging process, increasing labor costs. Furthermore, the interval between dredging and restoration can range from several days to several weeks. During this period, the riverbed loses its bottom sediment cover, making it susceptible to erosion by water flow, which alters the riverbed structure. Additionally, pollutants in the water may redeposit, causing the restoration environment to differ from the initial state after dredging. This, in turn, affects the effectiveness of restoration materials, making it difficult to achieve efficient synergy between dredging and restoration. Summary of the Invention

[0004] This invention provides an intelligent, efficient, and environmentally friendly device for dredging and in-situ remediation of black and odorous riverbed sediment. It aims to solve the problems of dredging and remediation being carried out in stages and having long operation cycles, resulting in the inability to coordinate dredging and remediation and low operation efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an intelligent, efficient, and environmentally friendly dredging and in-situ remediation device for black and odorous riverbed sediment, comprising: A connecting arm is connected to the robotic arm on the dredging vessel; the connecting arm has a tilting adjustment end; An aerated bucket is connected to the tilting adjustment end; the aerated bucket has a through cavity, and the aerated bucket can be driven by the tilting adjustment end to set the through cavity along the direction of travel of the dredging vessel; the bottom of the through cavity has an aeration section; the aerated bucket is used to allow silt from the bottom of the river to enter the through cavity as the dredging vessel moves, and to impact the silt through the aeration section; The suction structure has a suction end located at the top of the aeration bucket and communicating with the through cavity. The suction structure is used to extract and remove the sludge that is in a tumbling state in the through cavity. The repair component has a discharge end located at the tail of the aeration bucket for introducing repair material into the cleaned area after the aeration bucket has passed.

[0006] In one possible implementation, the aeration bucket includes: The top plate is connected to the flip-adjustment end and is used to fix the suction end in place. The base plate is arranged parallel to and spaced apart from the top plate; An aeration structure is disposed on the surface of the bottom plate near the top plate; the aeration structure provides the aeration section; The vessel has two side plates, both of which are located between the top plate and the bottom plate, and are spaced apart along the width of the dredging vessel; the two side plates, the top plate, the bottom plate, and the aeration structure together form the through cavity.

[0007] In one possible implementation, the aeration structure includes: A cover plate is fixedly mounted on the base plate. The cover plate has an inner cavity on its surface near the base plate. The cover plate has an inclined surface on its surface near the top plate. The inclined surface gradually rises in the vector direction from the inlet of the through cavity to the outlet of the through cavity. Multiple air holes are evenly distributed on the inclined surface, and each air hole forms an aeration section. A coil, arranged in a serpentine shape, is installed in the inner cavity, and multiple nozzles are evenly distributed on the coil. One end of the coil passes through the corresponding side wall and is connected to a gas compressor installed on the dredging vessel through a flow pipeline.

[0008] In one possible implementation, the connecting arm includes: The main boom has one end connected to the mechanical arm on the dredging vessel, and the other end rotatably connected to the auxiliary rod set on the top plate; The tilting frame has one end rotatably connected to the main arm and the other end rotatably connected to the auxiliary rod; the tilting frame is the tilting adjustment end. The telescopic structure has a fixed end that is rotatably connected to the main arm and a telescopic end that is rotatably connected to the tilting frame, and is used to drive the top plate to tilt and rotate via the tilting frame.

[0009] In one possible implementation, the suction structure includes: A suction cup, disposed on the top plate, has a suction port communicating with the through cavity; the suction cup is the suction end; The sludge suction pipe is connected at one end to the suction bucket and at the other end to the suction equipment installed on the dredging vessel.

[0010] In one possible implementation, the intake port is provided with a filter plate for filtering the gravel.

[0011] In one possible implementation, the repair component includes: A discharge hopper is fixedly mounted on the aeration shovel; the discharge hopper has a discharge port that covers the through cavity along the width direction of the through cavity; the discharge hopper is the discharge end; The discharge pipeline is connected at one end to the discharge hopper and at the other end to the conveying equipment installed on the dredging vessel.

[0012] In one possible implementation, the intelligent, efficient, and environmentally friendly dredging and in-situ remediation device for polluted riverbed sediment further includes: A leveling component is located behind the repair component and is rotatably connected to the aeration bucket; the leveling component has a plurality of trenching parts spaced apart along the width direction of the through cavity, and has a leveling cage; the leveling cage is located behind each trenching part along the direction of travel of the dredging vessel.

[0013] In this implementation, the aerated bucket is connected to the mechanical arm of the dredging vessel via a connecting arm, allowing it to be lowered to the bottom of the river channel to ensure the dredging work can proceed. The aerated bucket features a through-cavity with an aeration unit at its bottom. This aeration unit impacts the silt entering the through-cavity, causing it to tumble and facilitating extraction and discharge by the suction structure. This improves dredging efficiency and reduces the work cycle. The repair component at the tail end of the aerated bucket promptly introduces repair material to the riverbed after dredging, allowing it to be mixed with remaining gravel to cover the riverbed. This effectively shortens the time interval between dredging and repair, preventing erosion of the riverbed structure and avoiding the accumulation of pollutants due to long intervals. This ensures efficient coordination between dredging and repair, reduces manpower and material costs, and improves overall work efficiency. In addition, the leveling component set behind the repair component can open multiple uniform grooves on the mixed layer formed by the gravel and repair material through the trenching component, increasing the contact area between the repair material and the river water. At the same time, the leveling cage can compact the mixed layer after trenching to ensure the density of the mixed layer, thereby ensuring the repair effect. Attached Figure Description

[0016] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0017] Please refer to the following: Figures 1 to 3 This invention provides an intelligent, efficient, and environmentally friendly dredging and in-situ remediation device for black and odorous riverbed sediment. The device includes a connecting arm 10, an aeration bucket 20, a suction structure 30, and a remediation component 40. The connecting arm 10 is connected to a mechanical arm on a dredging vessel. The connecting arm 10 has a tilting adjustment end. The aeration bucket 20 is connected to the tilting adjustment end. The aeration bucket 20 has a through cavity 25, which can be aligned with the direction of travel of the dredging vessel by the tilting adjustment end. The bottom of the through cavity 25 has an aeration section. As the dredging vessel moves, the aeration bucket 20 allows silt from the bottom of the river to enter the through cavity 25, and the aeration section impacts the silt. The suction structure 30 has a suction end located at the top of the aeration bucket 20 and communicating with the through cavity 25. The suction structure 30 can extract and remove the sludge that is tumbling in the through cavity 25. The repair component 40 has a discharge end located at the tail of the aeration bucket 20, which can introduce repair material into the cleaned area after the aeration bucket 20 has passed.

[0018] Specifically, the working principle is as follows: after the connecting arm 10 is connected to the mechanical arm on the dredging vessel, the mechanical arm lowers the aeration bucket 20 to the bottom of the river channel. The aeration bucket 20 is then tilted and adjusted via the tilting adjustment end on the connecting arm 10, ensuring the tilting bucket is horizontal, i.e., the through-cavity 25 is horizontal. At this time, the through-cavity 25 is oriented along the direction of travel of the dredging vessel. During the dredging vessel's movement, silt enters the through-cavity 25 through its front end. The aeration unit then sprays high-pressure airflow to impact the silt, causing it to tumble. The tumbling silt is then sucked out by the suction structure 30. Simultaneously, if there are stones in the silt, they are directly discharged from the rear end (discharge end) of the through-cavity 25. During the dredging vessel's movement, the repair component 40 introduces repair material into the aeration bucket 20 or the rear end of the through-cavity 25 through its discharge end.

[0019] For ease of understanding, the direction of travel of the dredging vessel is the same as the length direction of the dredging vessel, and also the direction of penetration of the through cavity 25, while the width direction of the through cavity 25 is the same as the width direction of the dredging vessel.

[0020] The intelligent, efficient, and environmentally friendly dredging and in-situ remediation device for black and odorous riverbed sediment provided in this embodiment, compared with the prior art, features an aerated bucket 20 connected to the mechanical arm of the dredging vessel via a connecting arm 10. This allows the bucket to be lowered to the bottom of the river, ensuring the dredging work can proceed smoothly. The aerated bucket 20 is equipped with a through cavity 25, and an aeration unit is located at the bottom of the through cavity 25. This aeration unit impacts the silt entering the through cavity 25, causing it to tumble and churn. This facilitates the suction structure 30 in extracting and discharging the silt to the outside, improving the dredging effect and efficiency, and shortening the operation cycle. The repair component 40, located at the tail end of the aeration bucket 20, can promptly guide the repair material to the bottom of the river after dredging, allowing the repair material to cover the bottom of the river along with the remaining gravel. This method can effectively shorten the time interval between dredging and repair, prevent the riverbed structure from being altered by water flow, and also prevent the deposition of pollutants at the bottom of the river due to long intervals. This ensures efficient coordination between dredging and repair, reduces manpower and material resources, and improves work efficiency.

[0021] In some embodiments, the aeration bucket 20 described above can be adopted as follows: Figure 1 , Figure 2 , Figure 7 and Figure 8 The structure shown. See also Figure 1 , Figure 2 , Figure 7 and Figure 8 The aerated bucket 20 includes a top plate 21, a bottom plate 22, an aeration structure 23, and side plates 24. The top plate 21 is connected to the tilting adjustment end and is used for the fixed installation of the suction end. The bottom plate 22 is arranged parallel to and spaced apart from the top plate 21. The aeration structure 23 is arranged on the bottom plate 22 near the top plate 21. The aeration structure 23 provides an aeration section. There are two side plates 24, both located between the top plate 21 and the bottom plate 22, and the two side plates 24 are spaced apart along the width direction of the dredging vessel. The two side plates 24, the top plate 21, the bottom plate 22, and the aeration structure 23 enclose a through cavity 25.

[0022] The aeration bucket 20 is mainly composed of a top plate 21, a bottom plate 22, a side plate 24 and an aeration structure 23. Its structure is simple and the formed through cavity 25 has a large coverage area, which can ensure the dredging efficiency.

[0023] After the sludge enters the through-cavity 25, it is impacted by the aeration structure 23, causing it to tumble. At this time, any clumps of sludge can be broken down into small particles by the bubbles formed by the high-speed airflow. If there are gravel particles in the sludge, the high-speed bubbles will pass through the gravel, peeling off the sludge adhering to the gravel surface, ensuring that the sludge can be fully extracted, thereby ensuring the dredging effect.

[0024] It should be noted that the front end of the aeration bucket 20 is wedge-shaped, meaning the front end of the through cavity 25 is set at an angle, as can be seen in [reference needed]. Figure 1 and Figure 2 .

[0025] In some embodiments, the aeration structure 23 described above can be as follows: Figure 5 , Figure 7 and Figure 8 The structure shown. See also Figure 5 , Figure 7 and Figure 8 The aeration structure 23 includes a cover plate 231 and a coil 232. The cover plate 231 is fixed to the bottom plate 22, and an inner cavity is provided on the surface of the cover plate 231 near the bottom plate 22. The surface of the cover plate 231 near the top plate 21 has an inclined surface 234, which gradually rises in the vector direction from the inlet of the through cavity 25 to the outlet of the through cavity 25. Multiple air holes 235 are evenly distributed on the inclined surface 234, and each air hole 235 forms an aeration section. The coil 232 is arranged in a serpentine shape in the inner cavity, and multiple nozzles 236 are evenly distributed on the coil 232. One end of the coil 232 passes through the corresponding side wall and is connected to a gas compressor installed on the dredging vessel through a flow pipe 233.

[0026] The cover plate 231 is fixed to the base plate 22, and the cover plate 231 has an inclined surface 234. The inclined surface 234 slows down the movement of silt, thereby ensuring sufficient contact with the aeration unit. At the same time, the inclined surface 234 can also intercept gravel, ensuring sufficient impact of the gravel on the aeration unit, thus ensuring the dredging effect. Moreover, the gravel is relatively heavy, which can ensure that it continuously accumulates on the inclined surface 234, slowly passes through the inclined surface 234, and is discharged at the tail end of the through cavity 25, ensuring that the gravel falls evenly to the bottom of the river channel, thereby ensuring the subsequent restoration effect. Multiple air holes 235 provided on the inclined surface 234 can ensure the passage of airflow.

[0027] The serpentine arrangement of the coil 232 ensures coverage of the inner cavity, thus guaranteeing the length of the coil 232 within the cavity. After the multiple nozzles 236 spray airflow, bubbles are formed. These bubbles then form smaller bubbles after passing through the air holes 235. The smaller bubbles have a higher flow velocity, which further ensures the impact on the silt and the impact on the gravel, thereby ensuring the dredging effect.

[0028] In this embodiment, the gas compressor can be a screw gas compressor.

[0029] In some embodiments, the connecting arm 10 may be adopted as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5 The structure shown. See also Figure 1 , Figure 2 , Figure 4 and Figure 5 The connecting arm 10 includes a main arm 11, a tilting frame 12, and a telescopic structure 13. One end of the main arm 11 can be connected to the mechanical arm on the dredging vessel, and the other end is rotatably connected to an auxiliary rod 211 provided on the top plate 21. One end of the tilting frame 12 is rotatably connected to the main arm 11, and the other end is rotatably connected to the auxiliary rod 211. The tilting frame 12 is the tilting adjustment end. The fixed end of the telescopic structure 13 is rotatably connected to the main arm 11, and the telescopic end is rotatably connected to the tilting frame 12, enabling the top plate 21 to tilt and rotate via the tilting frame 12.

[0030] The main boom 11 can be fixed to the robotic arm, for example, by bolts. The main boom 11 is rotatably connected to the auxiliary rod 211, with the rotation axis aligned along the width of the through cavity 25. The rotation axis of the tilting frame 12 and the main boom 11 is also aligned along the width of the through cavity 25, as are the rotation axes of the tilting frame 12 and the auxiliary rod 211. The tilting frame 12 can include two rotatably connected frames, one rotatably connected to the main boom 11 and the other rotatably connected to the auxiliary rod 211, with the axis of the transition shaft between the two frames aligned along the width of the through cavity 25. The two frames, together with the main boom 11 and the auxiliary rod 211, form a four-bar linkage. The telescopic end of the telescopic structure 13 can be rotatably connected to the transition shaft on the tilting frame 12. This structure ensures that the tilting angle of the aeration bucket 20 can be adjusted during the telescopic structure 13's extension and retraction, thereby ensuring that the through cavity 25 corresponds to the bottom of the river channel, guaranteeing dredging effect and efficiency.

[0031] In some embodiments, the suction structure 30 described above can be as follows: Figure 2 , Figure 4 and Figure 5 The structure shown. See also Figure 2 , Figure 4 and Figure 5 The suction structure 30 includes a suction bucket 31 and a sludge suction pipe 32. The suction bucket 31 is mounted on the top plate 21 and has a suction port communicating with the through cavity 25. The suction bucket 31 is the suction end. One end of the sludge suction pipe 32 is connected to the suction bucket 31, and the other end is connected to the suction equipment installed on the dredging vessel.

[0032] The suction bucket 31 is installed on the top plate 21 and corresponds to the through cavity 25. It can ensure that the sludge inside the through cavity 25 can be extracted in time through the suction pipe 32 under the action of the suction equipment, thereby ensuring the sludge suction effect and sludge removal efficiency.

[0033] It should be noted that the suction device can be a mud pump. When the mud pump is connected to the suction bucket 31 via the mud suction pipe 32, the mud suction pipe 32 is a flexible pipe.

[0034] In some embodiments, the suction structure 30 described above can be as follows: Figure 4 The structure shown. See also Figure 4 The suction inlet is equipped with a filter plate 33 that can filter the gravel. The filter plate 33 can prevent the gravel from being discharged, thus ensuring that the gravel can remain at the bottom of the river as an auxiliary restoration material and realize the reuse of the gravel. At the same time, it can also prevent the suction pipe 32 from becoming blocked.

[0035] In some embodiments, the repair component 40 may employ, for example... Figure 2 , Figure 5 and Figure 6 The structure shown. See also Figure 2 , Figure 5 and Figure 6 The repair component 40 includes a discharge hopper 41 and a discharge pipe 42. The discharge hopper 41 is fixed on the aeration bucket 20. The discharge hopper 41 has a discharge port that covers the through cavity 25 along its width. The discharge hopper 41 is the discharge end. One end of the discharge pipe 42 is connected to the discharge hopper 41, and the other end is connected to the conveying equipment installed on the dredging vessel.

[0036] The discharge hopper 41 is located at the tail end of the through cavity 25, ensuring that the repair material is promptly discharged to the bottom of the river after dredging. The mixed layer formed by the repair material and gravel achieves high efficiency in in-situ repair, avoiding erosion of the river bottom by water flow and preventing the deposition of pollutants. Furthermore, the resulting mixed layer has good density, preventing it from being washed away by the water flow. The discharge port of the discharge hopper 41 covers the entire through cavity 25 along its width, ensuring that the repair material is evenly distributed across the dredged area, thus guaranteeing the repair effect. Simultaneously, the conveying equipment ensures that the repair material is introduced into the discharge hopper 41 through the discharge pipe 42.

[0037] The conveying equipment can be a conveying pump; or a sealed storage tank equipped with a negative pressure pump to convey the material under pressure.

[0038] In some embodiments, see Figure 1 , Figure 2 , Figure 9 and Figure 10 The intelligent, efficient, and environmentally friendly dredging and in-situ remediation device for black and odorous riverbed sediment also includes a leveling component 50. The leveling component 50 is located behind the remediation component 40 and is rotatably connected to the aeration bucket 20. The leveling component 50 has multiple trenching elements 53 spaced apart along the width direction of the through cavity 25, and a leveling cage 54. The leveling cage 54 is located behind each trenching element 53 along the direction of travel of the dredging vessel.

[0039] The leveling component 50, located behind the repair component 40, can create multiple uniform grooves on the mixed layer formed by the gravel and repair material through the trenching component 53, increasing the contact area between the repair material and the river water. At the same time, the leveling cage 54 can compact the mixed layer after trenching, ensuring the density of the mixed layer and thus ensuring the repair effect.

[0040] It should be noted that although the rat cage compacts the mixed layer, it does not flatten the resulting trenches. The compacted mixed layer will still have multiple trenches arranged side by side.

[0041] Specifically, the leveling assembly 50 may include a front hinge frame 51 rotatably connected to the top plate 21 and a rear hinge frame 52 rotatably connected to the front hinge frame 51. Each trenching member 53 is fixed to the bottom of the front hinge frame 51, while the leveling cage 54 is rotatably mounted on the rear hinge frame 52. (See also...) Figure 9 and Figure 10 .

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
