Description

Technical Field

[0001] This invention belongs to the field of river sludge treatment technology, specifically relating to a high-efficiency dredging and treatment device for black and odorous rivers that integrates real-time water quality monitoring. Background Technology

[0002] As a key target for urban water environment management, black and odorous rivers and canals have silt that accumulates at the bottom for a long time. This silt not only accumulates a large amount of nutrients such as nitrogen and phosphorus as well as heavy metals, but also produces malodorous gases such as hydrogen sulfide due to anaerobic decomposition. This leads to a continuous decline in dissolved oxygen in the water and damage to the aquatic ecosystem. At the same time, it has a serious impact on the living environment of the surrounding residents. Therefore, it is necessary to use dredging equipment to clean up the silt accumulated at the bottom of the rivers and canals in a timely manner.

[0003] Existing technologies for dredging black and odorous rivers mainly include cutter suction dredgers and grab bucket dredgers. Taking cutter suction dredgers as an example, their working principle involves a rotating cutter that cuts the bottom sediment into slurry, which is then pumped by a centrifugal pump into a slurry transport pipeline and finally transported to an off-site storage area for dewatering. Grab bucket dredgers, on the other hand, use a robotic arm to grab clumps of sludge and transfer them to a transport vessel. The core principle of both types of devices is to rely on mechanical force to break down the bottom sediment structure and move the sludge. However, both of these dredging methods require staff to regularly inspect areas prone to sludge accumulation. Once sludge accumulation is detected in the river, dredging equipment must be mobilized from elsewhere to the affected area for dredging, leading to untimely dredging and increased cleaning costs. Summary of the Invention

The monitoring components continuously monitor in real time, automatically triggering the dredging process once a threshold is reached, achieving timeliness and automation, and significantly improving dredging efficiency. Moreover, the sealed space formed by the dredging components confines the silt to be cleaned to a specific area, preventing silt spread and polluting surrounding water bodies during the cleaning process, ensuring thorough silt removal and guaranteeing dredging quality. In addition, this dredging method can reduce manual intervention, lower labor and equipment scheduling costs, and avoid problems such as water deterioration and ecological damage caused by untimely dredging, making it highly practical.

[0018] 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.

[0019] Please refer to the following: Figure 1 and Figure 2This invention provides a high-efficiency dredging and treatment device for black and odorous rivers that integrates real-time water quality monitoring. The device includes a fixed base 10, a monitoring component 20, a dredging component 30, a drive component 40, and a matching controller. Two fixed bases 10 are provided, positioned at opposite ends of the river along its width, forming a flow channel. The monitoring component 20 is located within the flow channel and connected to both fixed bases 10, enabling real-time monitoring of water quality and the height of silt accumulation at the bottom of the flow channel. Two dredging components 30 are provided, slidably connected to sliding cavities 11 on the two fixed bases 10, and both dredging components 30 are located below the monitoring component 20. The drive component 40 is connected to both dredging components 30. After the silt accumulation height exceeds a threshold, the two sludge removal components 30 move relative to each other and align, forming a sealed space with the bottom of the flow channel. Each sludge removal component 30 can then clean the silt within the sealed space.

[0020] The working principle is as follows: two fixed seats 10 are set at both ends along the width of the river, with their tops protruding above the water surface. A flow channel for river water circulation is formed between the two fixed seats 10. The fixed seats 10 provide a stable installation foundation for the entire device without obstructing the natural flow of water. The controller receives water quality data and silt accumulation height data transmitted by the monitoring component 20 in real time. When the silt accumulation height exceeds a preset threshold, the controller immediately sends a command to the drive component 40. The drive component 40 drives the two dredging components 30 to slide out of the sliding cavity 11 and slide relative to each other until they are completely aligned to form a sealed space. Then, the dredging components 30 start to clean the silt in the sealed space.

[0021] The high-efficiency dredging device for black and odorous rivers provided in this embodiment integrates real-time water quality monitoring. Compared with existing technologies, the monitoring component 20 is connected between two fixed seats 10 and located in the flow channel, adapting to rivers of different widths. It does not require large-scale river modifications, is easy to install, and has a wide range of applications. It not only achieves real-time water quality monitoring but also accurately captures the height of silt accumulation at the bottom of the channel. Its cooperation with the controller constitutes a real-time sensing system. The two dredging components 30 are slidably connected to the fixed seats 10 through the sliding cavity 11. Driven by the drive component 40, they can move relative to each other and align. After alignment, they form a sealed space with the bottom of the flow channel, and the silt within this space is cleaned. This dredging method does not require regular inspections by staff. The monitoring component 20 continuously monitors in real time, and automatically triggers the dredging process once a threshold is reached, achieving timeliness and automation of dredging and significantly improving dredging efficiency. Moreover, the sealed space formed by the dredging components 30 after alignment can confine the silt to be cleaned to a specific area, preventing the silt from spreading and polluting the surrounding water during the cleaning process, ensuring the thoroughness of silt removal, and guaranteeing the quality of dredging. In addition, this dredging method can reduce manual intervention, lower labor and equipment scheduling costs, and avoid problems such as water deterioration and ecological damage caused by untimely dredging, making it highly practical.

[0022] In some embodiments, the monitoring component 20 described above may employ, for example... Figure 8 and Figure 9 The structure shown. See figure. Figure 8 and Figure 9 The monitoring component 20 includes an outer frame 21 and an orifice plate 22. The outer frame 21 is horizontally positioned and connected to two fixed bases 10 at both ends. Multiple water quality sensors 23 are spaced apart along the outer edge of the outer frame 21, and each water quality sensor 23 is electrically connected to the controller. The orifice plate 22 is housed within the outer frame 21. Multiple distance sensors 24 are evenly distributed at the bottom of the orifice plate 22, and each distance sensor 24 is electrically connected to the controller.

[0023] The outer frame 21 is horizontally positioned and connected to the mounting base 10 at both ends, providing a stable mounting platform for the monitoring component 20. Multiple water quality sensors 23, spaced apart along its outer edge, are electrically connected to the controller, enabling the collection of water quality data from different locations. The orifice plate 22 is located inside the outer frame 21, with multiple distance sensors 24 evenly distributed at its bottom, also electrically connected to the controller, capable of monitoring the sludge accumulation height at the bottom of the flow channel. The multiple water quality sensors 23 on the outer edge of the outer frame 21 operate synchronously, capturing water quality parameters such as dissolved oxygen and nitrogen / phosphorus content from different areas within the flow channel, and transmitting the data to the controller in real time for comprehensive water quality monitoring. The multiple distance sensors 24 evenly distributed at the bottom of the orifice plate 22 measure the distance to the sludge surface from different points, and the controller calculates the sludge accumulation height, ensuring the accuracy of the monitoring data.

[0024] Both the water quality sensor 23 and the distance sensor 24 are electrically connected to the controller, enabling real-time and efficient data transmission. The controller can quickly receive and analyze the monitoring data, promptly determine whether the dredging process needs to be initiated, avoid delays in dredging due to monitoring lag, and ensure the efficient progress of dredging work.

[0025] In some embodiments, see Figure 8 The high-efficiency dredging and treatment device for black and odorous rivers, which integrates real-time water quality monitoring, also includes a power generation component 50. The power generation component 50 includes a main shaft 51, impellers 52, a reduction gearbox 53, and a generator 54. The main shaft 51 is arranged along the interval between two fixed seats 10, and its two ends are rotatably connected to the two fixed seats 10 respectively. Multiple impellers 52 are provided, each located in a flow channel and spaced apart on the main shaft 51. Each impeller 52 has multiple collection plates arranged annularly around the axis of the main shaft 51, and each collection plate can drive the impeller 52 to rotate with the water flow. The reduction gearbox 53 is located in one of the fixed seats 10 and is poweredly connected to one end of the main shaft 51. The generator 54 is poweredly connected to the output end of the reduction gearbox 53 and electrically connected to a battery located in the fixed seat 10.

[0026] The main shaft 51 is arranged along the interval direction of the two fixed seats 10, and its two ends are rotatably connected to the fixed seats 10, providing a base for the installation and rotation of the impellers 52. Multiple impellers 52 are located in the flow channel and spaced apart on the main shaft 51. Multiple collection plates of each impeller 52 are arranged in a ring around the axis of the main shaft 51, which can drive the impeller 52 to rotate under the action of water flow. The input end of the reduction gearbox 53 is poweredly connected to the main shaft 51, and the speed of the main shaft 51 can be adjusted. The generator 54 is poweredly connected to the output end of the reduction gearbox 53 and electrically connected to the battery inside the fixed seat 10, converting mechanical energy into electrical energy and storing it in the battery. The battery provides power to the electrical components of the entire dredging device, such as sensors, controllers, and dredging components 30.

[0027] The power generation component 50 generates electricity using the kinetic energy of water and stores it in a battery, providing a continuous and stable power supply for the device. This avoids the limitations of traditional dredging equipment that relies on external power sources or fuel-powered generators, ensuring that the monitoring component 20 works continuously in real time and the dredging component 30 can be started at any time, thus guaranteeing the efficient operation of the dredging work.

[0028] In some embodiments, the dredging component 30 may employ, for example... Figures 3 to 7 The structure shown. See also Figures 3 to 7Each dredging component 30 includes a sliding box 31, a suction structure 32, and a filter structure 33. The sliding box 31 is slidably connected to the sliding cavity 11 and has an inner cavity. The bottom end of the sliding box 31 is open, and the end of the sliding box 31 facing the other dredging component 30 is also open. The suction structure 32 is disposed in the inner cavity and connected to the sliding box 31, and the suction structure 32 can suction the sludge in the inner cavity. The filter structure 33 is disposed in the inner cavity and connected to the suction structure 32, and the filter structure 33 can receive the sludge from the suction structure 32 and filter the sludge.

[0029] Among them, after the two dredging components are put together, the two inner cavities combine to form a sealed space.

[0030] When the controller commands the drive component 40 to move and engage the two sludge removal components 30 relative to each other, the inner cavities of the two sliding boxes 31 combine to form a sealed space, enclosing the sludge to be cleaned within this space. Subsequently, the suction structure 32 is activated, drawing the sludge from the sealed space into the filter structure 33, where the filter structure 33 filters the sludge, achieving separation of the sludge from the water.

[0031] The open design of the sliding box 31 facilitates the rapid entry of sludge into the inner cavity. The suction structure 32 directly acts on the sludge within the sealed space, with a short suction path, quickly drawing the sludge to the filter structure 33 and reducing the sludge's residence time during the cleaning process. The filter structure 33 is directly connected to the suction structure 32, allowing for immediate filtration after sludge suction without additional transport, shortening the dredging cycle and improving overall dredging efficiency. The two dredging components 30, when joined together, form a sealed space, effectively preventing sludge diffusion during suction and ensuring all sludge enters the filter structure 33 for treatment. The filter structure 33 separates the sludge from the water, preventing the cleaned water from carrying large amounts of fine sludge back into the river, ensuring the water quality after dredging. Simultaneously, the separated sludge can be centrally disposed of, avoiding secondary pollution and improving the thoroughness and environmental friendliness of the dredging process. The suction structure 32 and the filter structure 33 are integrated in the inner cavity of the sliding box 31, which is compact, reduces the space occupied by the device, and facilitates installation and maintenance; the filter structure 33 filters the sludge, making sludge disposal more convenient.

[0032] In some embodiments, the sliding box 31 described above may be as follows: Figure 4 The structure shown. See also Figure 4 The sliding box 31 has a grating plate 34 at one end facing the other dredging component 30.

[0033] When the two dredging components 30 move and engage relative to each other, the grating plate 34 at the open end of the sliding box 31 simultaneously approaches and adheres to the surface. While forming a sealed space, the grating plate 34 intercepts large debris such as branches, stones, and fish in the water, preventing them from entering the inner cavity of the sliding box 31. The grating plate 34 can intercept large debris in advance, preventing it from entering the inner cavity of the sliding box 31 and clogging the suction structure 32 or the filter structure 33. This reduces dredging interruptions caused by equipment blockage, ensures the continuous operation of the dredging process, and improves the efficiency of the dredging work.

[0034] It should be noted that the bottom end of the grating plate 34 may be provided with serrations, which can ensure that the tips of the serrations break the silt bottom layer during sliding, thus ensuring smooth sliding. In addition, multiple vertically arranged limiting strips can be provided on the opposing surfaces of the two grating plates 34. The limiting strips on the two grating plates 34 are staggered. After the two sliding boxes 31 are engaged, the limiting strips on the two grating plates 34 can form a tongue-and-groove engagement, thereby ensuring the stability of the two sliding boxes 31 after engagement.

[0035] In some embodiments, the suction structure 32 described above can be as follows: Figure 3 , Figure 5 and Figure 6 The structure shown. See also Figure 3 , Figure 5 and Figure 6 The suction structure 32 includes a connecting seat 321, a transfer box 322, and telescopic rods 323. The connecting seat 321 is fixed on the sliding box 31. The transfer box 322 is located below the connecting seat 321, and multiple suction heads 324 are evenly distributed at the bottom of the transfer box 322. The transfer box 322 is connected to the filter structure 33 through a flexible telescopic tube 325. Multiple telescopic rods 323 are provided, and each telescopic rod 323 is evenly distributed between the connecting seat 321 and the transfer box 322, with one end of each telescopic rod 323 connected to the connecting seat 321 and the other end connected to the transfer box 322.

[0036] During dredging, the telescopic rod 323 extends and retracts according to the height of the silt accumulation, causing the transfer box 322 to move up and down, so that the multiple sludge suction heads 324 at the bottom come into contact with the silt surface. Then, the sludge suction heads 324 start to suck up the silt. After the silt is collected through the transfer box 322, it is transported to the filter structure 33 for treatment through the flexible telescopic pipe 325.

[0037] Multiple suction heads 324 are evenly distributed at the bottom of the transfer box 322, expanding the coverage area of ​​a single suction operation. This allows for simultaneous suction of sludge from multiple points, increasing the amount of sludge suctioned per unit time. The even distribution of the suction heads 324 ensures complete coverage of the sludge area within the sealed space, avoiding suction dead zones and ensuring thorough sludge removal, thus improving the completeness of the dredging process. The telescopic rod 323 allows for flexible adjustment of the height of the transfer box 322, ensuring that the suction heads 324 always remain in contact with the sludge surface. This prevents reduced suction efficiency due to excessive distance between the suction heads 324 and the sludge surface, ensuring efficient suction and shortening dredging time. The telescopic rod 323 adjusts the height of the transfer box 322, allowing the suction head 324 to adapt to silt accumulations of different thicknesses. For thicker silt accumulations, the transfer box 322 can be lowered to allow the suction head 324 to penetrate deeper into the silt layer, achieving effective suction of deep silt and avoiding the residue of deep silt after surface silt removal, thus further ensuring the dredging effect.

[0038] In some embodiments, the suction structure 32 described above can also employ, for example... Figure 5 The structure shown. See also Figure 5 The suction structure 32 may also include a storage tank 326, which is positioned above the connecting seat 321 and contains purification liquid. A delivery pipe 327 is connected to the bottom of the storage tank 326 and is connected to a transfer box 322. After the suction structure 32 draws the sludge into the transfer box 322, the storage tank 326 can release the purification liquid into the transfer box to ensure the purification of the sludge.

[0039] In some embodiments, the suction structure 32 described above can also employ, for example... Figure 10 and Figure 11 The structure shown. See also Figure 10 and Figure 11 The suction structure 32 may further include an auxiliary assembly 35, which includes a rotating shaft 351, a turbine 352, a first bevel gear 353, a second bevel gear 354, a reciprocating screw 355, and a scraper 356. The rotating shaft 351 is vertically arranged and rotatably positioned at the outlet of the intermediate transfer box 322. The turbine 352 is coaxially mounted on the rotating shaft 351 and can passively rotate during fluid discharge at the outlet. The first bevel gear 353 is coaxially connected to the rotating shaft 351, the second bevel gear 354 meshes with the first bevel gear 353, the reciprocating screw 355 is coaxially connected to the second bevel gear 354, and the scraper 356 is slidably positioned within the intermediate loading box along the interval direction of the two fixed seats 10 and is helically connected to the reciprocating screw 355.

[0040] During the suction process, the fluid impact turbine 352 drives the rotating shaft 351 to rotate, which in turn transmits power to the second bevel gear 354 through the first bevel gear 353. Subsequently, the reciprocating screw 355 rotates to drive the scraper 356 to reciprocate within the transfer box 322, ensuring that impurities attached to the inner wall of the transfer box 322 are cleaned, thus ensuring the cleanliness of the transfer box 322 and guaranteeing the sludge removal effect.

[0041] In some embodiments, the filter structure 33 described above can be as follows: Figure 6 and Figure 7 The structure shown. See also Figure 6 and Figure 7 The filtration structure 33 includes a processing chamber 331 and a negative pressure pump 332. The processing chamber 331 has a filter section 333 inside, which divides the processing cavity of the processing chamber 331 into a feeding chamber and a filtering chamber. The feeding chamber is connected to a flexible telescopic tube 325. The negative pressure pump 332 is mounted on the processing chamber 331 and is connected to the feeding chamber.

[0042] After the negative pressure pump 332 is started, a negative pressure environment is formed in the feeding chamber. Under the action of negative pressure, the sludge in the transfer box 322 is sucked into the feeding chamber through the flexible telescopic tube 325. After the sludge enters the feeding chamber, it comes into contact with the filter section 333. The filter section 333 intercepts the solid particles in the sludge, and the filtered water enters the filter chamber, realizing the separation of sludge and water.

[0043] The negative pressure pump 332 provides continuous and stable power for sludge suction and filtration, accelerating the sludge transport speed from the transfer box 322 to the feed chamber, while promoting contact between the sludge and the filter section 333, improving filtration efficiency, shortening the sludge treatment cycle, and ensuring the efficient progress of the dredging process. The negative pressure environment ensures that the sludge is fully sucked into the feed chamber, preventing sludge residue in the transfer box 322 or flexible expansion tube 325, thus improving the thoroughness of sludge suction. The filter section 333 in the treatment box 331 has a significant separation effect, effectively trapping solid particles in the sludge, improving the water quality after filtration, preventing water carrying fine sludge from flowing back into the river, and ensuring the quality of the water after dredging. The filtered sludge is concentrated in the feed chamber, facilitating subsequent centralized disposal, avoiding secondary pollution, and further improving the dredging effect. The filter section 333 divides the treatment chamber into a feed chamber and a filter chamber, allowing the sludge feeding and filtration processes to be carried out in separate areas, further improving treatment efficiency.

[0044] In some embodiments, the filter structure 33 described above can be as follows: Figure 6 and Figure 7 The structure shown. See also Figure 6 and Figure 7 The filter structure 33 also includes a water pump 334, which is installed on the treatment box 331 and is connected to the filter chamber.

[0045] After the negative pressure pump 332 drives the sludge suction and filtration, the filtered water is collected in the filtration chamber. At this time, the water pump 334 starts and quickly discharges the clean water in the filtration chamber into the treatment tank 331, which can be directly returned to the river or used for other recycling.

[0046] Pump 334 can quickly discharge the filtered water from the filter chamber, preventing a decrease in filtration speed due to water pressure buildup and ensuring continuous and efficient filtration. Timely discharge of the filtered water creates space for subsequent sludge suction and filtration, forming a closed loop in the dredging process and preventing interruptions due to delayed water discharge, thus ensuring the continuity and efficiency of the dredging work. The rapid discharge of filtered water by pump 334 reduces the residence time of water in the filter chamber, preventing the filtered water from mixing with unfiltered sludge and ensuring the cleanliness of the discharged water. Furthermore, the rapid discharge of water creates a certain water flow force, facilitating full contact between the sludge in the feed chamber and the filter section 333, improving the filtration effect.

[0047] Water pump 334 can be a water-air dual-purpose pump, which can be used in conjunction with negative pressure pump 332 to simultaneously apply negative pressure, so as to ensure both suction and filtration efficiency.

[0048] In some embodiments, the processing box 331 described above may employ, as follows: Figure 3 The structure shown. See also Figure 3 The processing box 331 is set in the corresponding fixed seat 10.

[0049] The sliding box 31 has a connecting pipe on its side wall away from the other dredging component 30. Two flexible expansion tubes 325 are provided; one flexible expansion tube 325 is connected to both the connecting pipe and the transfer box 322. The other flexible expansion tube 325 is connected to both the connecting pipe and the treatment box 331.

[0050] The processing box 331 is set in the fixed base 10, which can ensure that its volume is increased and facilitates the stability of its operation.

[0051] The sludge sucked by the suction structure 32 is collected in the transfer box 322 and then transported to the connecting pipe through one of the flexible expansion tubes 325. It is then transported to the treatment box 331 in the fixed seat 10 through the other flexible expansion tube 325. The sludge is then filtered by the filter section 333 in the treatment box 331, which realizes the long-distance transportation and centralized treatment of sludge while ensuring the airtightness of the sealed space.

[0052] In some embodiments, the driving component 40 described above may employ, for example... Figure 3 and Figure 4 The structure shown. See also Figure 3 and Figure 4The drive assembly 40 includes a guide rod 41, a bidirectional lead screw 42, and a driver 43. The guide rod 41 is arranged along the interval direction of the two fixed seats 10, and its two ends pass through the sliding cavity 11 and are fixedly connected to the two fixed seats 10. The guide rod 41 is slidably connected to the sliding box 31. The bidirectional lead screw 42 is arranged along the interval direction of the two fixed seats 10 and is rotatably connected to the two fixed seats 10. The bidirectional lead screw 42 has two helical portions with opposite directions of rotation, and the two helical portions are respectively helically engaged with the nut portions provided on the two sliding seats. The driver 43 is mounted on one of the fixed seats 10 and is poweredly connected to the bidirectional lead screw 42.

[0053] When dredging needs to be started, the controller sends a command to the driver 43, which drives the bidirectional lead screw 42 to rotate. Since the two helical parts of the bidirectional lead screw 42 rotate in opposite directions and respectively cooperate with the nut parts of the two sliding boxes 31, the two sliding boxes 31 will move relative to each other along the guide rod 41 under the guidance of the guide rod 41 until they are aligned to form a sealed space. After dredging is completed, the driver 43 drives the bidirectional lead screw 42 to rotate in the opposite direction, and the two sliding boxes 31 move in the opposite direction to reset.

[0054] Specifically, two guide rods 41 can be provided, both located at the top of the sliding box 31, or respectively located on the two side walls of the sliding box 31, and slidably connected to the sliding joint on the sliding box 31. At the same time, the nut can be provided at the top or side wall of the sliding box 31.

[0055] The actuator 43 drives the bidirectional lead screw 42 to rotate, precisely controlling the moving speed and stroke of the sliding box 31. This allows the two dredging components 30 to engage quickly and accurately, shortening the dredging preparation time. The helical drive of the bidirectional lead screw 42 has high transmission efficiency, efficiently transmitting the power of the actuator 43 to the sliding box 31. This ensures smooth movement of the sliding box 31, avoids jamming, and guarantees that the dredging components 30 respond quickly to dredging commands, improving overall dredging efficiency. The guide rod 41 provides stable guidance for the sliding box 31, ensuring that the two sliding boxes 31 remain parallel during movement. This prevents misalignment and ensures a tight seal after engagement, preventing sludge spread and guaranteeing thorough dredging.

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.
