Description

A river ecological management device and its management method Technical Field

[0001] This invention relates to the technical field of river ecological management, specifically to a river ecological management device and its management method. Background Technology

[0002] In the process of river water ecological management, it is necessary to dredge the river and clean up surface garbage. Currently, the dredging of river silt is generally carried out by pumping water pumps to extract and process the silt. However, during the silt extraction process, stones are usually mixed in with the silt. Therefore, the collected silt needs to be separated later, which makes the operation inconvenient. Moreover, if too many stones accumulate, it will affect the effectiveness of the dredging process. Therefore, it is necessary to separate the silt from the stones through separation devices. However, the existing separation devices are complex in structure. In addition, the current method of cleaning up surface garbage in the river is generally done manually. Manual operation is relatively expensive and inefficient. Therefore, improvements are needed. Summary of the Invention

The funnel chamber is fixed below the upper fixing ring, and a flexible hose is connected below the funnel chamber. The lower end of the flexible hose is connected to the inlet end of the water separation chamber fixed on the lower fixing ring. An inclined guide pipe is installed in the hull, and the lower end of the guide pipe is located at the bottom of the hull and communicates with the river channel. At least one monitoring camera is installed on both sides of the hull. Each monitoring camera is fixed to the hull by a monitoring bracket. An ultrasonic rangefinder is also installed on the monitoring bracket on the right side of the hull. The input end of the sludge purification tank is connected to the output port on the right side of the water separation chamber. A sewage outlet is installed above the sludge purification tank.

[0018] This invention also discloses a method for river ecological management, including the aforementioned river ecological management equipment, characterized by the following specific steps:

[0019] S1. Place the boat in the river channel that needs to be cleaned, and adjust the depth of each water pump in advance according to the depth requirements of the river channel to suck up silt from different depths at the bottom of the river channel.

[0020] S2. Then, the sucked-up sludge is sent into the rotating filter screen. At this time, the driving adjustment cylinder works to circulate gas into the upper fixed ring, which in turn drives the internal annular piston to rotate. The rotation of the annular piston drives the lower gear to rotate, which in turn drives the upper gear to rotate, and finally drives the annular gear II to rotate, so as to realize the rotation of the rotating filter screen. At the same time, the control cabinet drives four lifting cylinders to operate at different heights and different process times to ensure that the upper fixed ring swings up and down and rotates in coordination, so as to achieve the effect of filtering sludge and large stones.

[0021] S3. The filtered sludge falls through the funnel chamber into the water separation chamber, where water and sludge are separated. The water flows directly back into the river channel through the guide pipe, while the sludge enters the sludge purification tank.

[0022] S4. The sludge purification tank allows the sludge to come into full contact with microorganisms, which then decompose and purify the sludge. The degraded sludge is returned to the river through the sewage pipe, while the undegraded sludge can be sucked out from the sewage outlet later by a suction pump. Later, when there are too many stones on the rotating filter screen, a pneumatic gripper equipped with a stone cleaning soft robotic arm is used to clean and collect the stones on the rotating filter screen.

[0023] S5. Using the monitoring cameras on both sides, the vessel will monitor the river surface on both sides in real time for floating garbage. If garbage is detected on the right side of the vessel, the vessel will use an ultrasonic rangefinder to measure the distance between the garbage and the vessel. The vessel will then move to the vicinity of the garbage, attach a scoop net to the pneumatic gripper, and drive the garbage-cleaning soft robotic arm to scoop up the garbage and dump it into the garbage collection pool. At the same time, if the monitoring camera on the left side detects garbage on the left side, the vessel will first clean up the garbage on the right side, and then rotate the vessel to use the garbage-cleaning soft robotic arm to clean up the garbage on the left side in the same way as the right side.

[0024] Preferably, in step S5, the monitoring cameras on both sides detect whether there is floating garbage on the river surface on both sides of the hull in real time by pre-creating and storing photos of the river surface without garbage in the control cabinet as reference photos, then using the monitoring cameras to take photos of the river surface in real time, and then comparing them with the pre-created reference photos to determine whether there is garbage in the river.

[0025] Compared with the prior art, the present invention has the following beneficial effects: the present invention can realize the automatic retrieval of garbage in the river channel, and through a simple structure, it can quickly separate silt and stones, making the entire structure simple and convenient to operate.

[0042] Surveillance camera 9; used to monitor the environment on the surface of the river and automatically detect the location of garbage;

[0044] The sludge separation components 4 are spaced apart along the length of the hull 1, and each sludge separation component 4 includes a lower fixing ring 401, an upper fixing ring 402, a water separation chamber 403, a funnel chamber 404, and a lifting cylinder 405. The lower fixing ring 401 is fixed to the hull 1, and four hinge seats 406 are annularly hinged to the lower fixing ring 401. Each hinge seat 406 is fixed with one of the lifting cylinders 405. The upper fixing ring 402 is hinged between the piston rods of the four lifting cylinders 405, and a ring is movably connected within the upper fixing ring 402. A ring piston 407 has a lower gear 408 rotatably connected to the side of an upper fixed ring 402. An upper gear 409 is fixed to the lower gear 408. The side of the ring piston 407 has an annular tooth 410 that meshes with the lower gear 408. A positioning cover 411 covers the top of the ring piston 407. A rotating filter screen 412 is rotatably connected inside the positioning cover 411. The output end of the water pump 2 is connected to a corresponding rotating filter screen 412. The side of the rotating filter screen 412 has an annular tooth 413 that meshes with the upper gear 409. Two gears 413 that mesh with the upper gear 409 are provided on the side of the upper fixed ring 402. The cylinder connection port 414 is internally connected to the fixed ring 402. The funnel chamber 404 is fixed above the lower part of the upper fixed ring 402, and a hose 415 is connected below the funnel chamber 404. The lower part of the hose 415 is connected to the inlet end of the water separation chamber 403 fixed on the lower fixed ring 401. An inclined guide pipe 416 is provided inside the hull 1. The lower part of the guide pipe 416 is located at the bottom of the hull 1 and communicates with the river channel. At least one monitoring camera 9 is provided on both sides of the hull 1. Each monitoring camera 9 is fixed to the hull 1 by a monitoring bracket 417. An ultrasonic rangefinder 418 is also installed on the monitoring bracket 417 on the right side of the body 1. The input end of the sludge purification tank 6 is connected to the output port 425 on the right side of the water separation chamber 403. A sewage outlet 419 is provided above the sludge purification tank 6. The bottom of the sludge purification tank 6 is connected to the sewage pipe 420 inside the hull 1. The lower end of the sewage pipe 420 is connected to the river channel. The control cabinet 10 is electrically connected to the monitoring camera 9, the stone cleaning soft robot 5, the lifting cylinder 405, and the garbage cleaning soft robot 8. An adjusting cylinder 421 connected to the cylinder connection port 414 is fixed on the control cabinet 10.

[0045] The working principle of this structure is as follows: During use, the hull 1 is placed in the river channel to be cleaned. The depth of each water pump 2 is adjusted beforehand according to the required river depth to extract silt from different depths at the bottom of the river. The extracted silt is then fed into the rotating filter screen 412. At this time, the adjusting cylinder 421 is activated, circulating gas into the upper fixed ring 402. This, in turn, drives the internal annular piston 407 to rotate. The rotation of the annular piston 407 drives the lower gear 408 to rotate, simultaneously driving the upper gear 409 to rotate, ultimately driving the annular gear 413 to rotate, thus achieving... The rotating filter screen 412 rotates, and simultaneously, the control cabinet 10 drives four lifting cylinders 405 to operate at different heights and for different time periods to ensure that the upper fixed ring 402 swings up and down in coordination with the rotation, ultimately achieving the effect of filtering silt and large stones. The filtered silt falls through the funnel chamber 404 into the water separation chamber 403, where water and silt are separated. The water flows directly back into the river channel through the guide pipe 416, while the silt enters the silt purification tank 6, where it can fully contact with microorganisms, utilizing the microorganisms... The sludge is fully decomposed and purified after the reaction. The degraded sludge is returned to the river channel through the sewage pipe 420, while the undegraded sludge can be sucked out from the sewage outlet 419 by a suction pump. Later, when there are too many stones on the rotating filter screen 412, the stones on the rotating filter screen 412 are cleaned and collected by the pneumatic gripper 501. At the same time, when cleaning up garbage, the monitoring cameras 9 on both sides of the ship 1 are used to detect in real time whether there is floating garbage on the surface of the river channel on both sides of the ship 1. If garbage is detected on the surface of the river channel on the right side of the ship 1, the ultrasonic rangefinder 418 is used to measure the distance between the garbage and the ship 1. The boat moves hull 1 to the vicinity of the garbage, pre-attaches a scoop net to the pneumatic gripper 502, and drives the garbage-cleaning flexible robotic arm 8 to work. The scoop net is used to scoop up the garbage and pour it into the garbage collection pool 7. At the same time, if the monitoring camera 9 on the left detects garbage on the left, the garbage on the right is cleaned first, and then the hull 1 is rotated to use the garbage-cleaning flexible robotic arm 8 to clean up the garbage on the left in the same way as on the right. Therefore, this invention can realize the automatic scooping of garbage in the river channel, and the simple structure can quickly separate silt and stones, making the whole structure simple and convenient to operate.

[0046] In this embodiment, the hull 1 is a hull with a cabin, and the space in the cabin allows the hull 1 to float on the water. The hull's position can be changed by a person using oars or the ship's own power unit. The hull is equipped with a deck for mounting other components of the sewage treatment vessel. In a specific implementation, the water pump 2 can be suspended from the hull by chains or other slings. Furthermore, to accommodate different water depths, the slings for suspending the water pump 2 can be connected to a winch device (not shown) located on the hull, allowing adjustment of the water pump 2's depth in the water source. Additionally, the hull of this invention can employ multiple water pumps 20 (six or more in this embodiment), and during operation, the multiple water pumps 20 can be positioned at different depths relative to each other.

[0047] Meanwhile, to prevent misalignment during movement, an annular slide rail 4021 is provided on the upper fixed ring 402, and a slider 4022 is slidably connected on the annular slide rail 4021. The slider 4022 is fixed on the rotating filter screen 412. The above structure facilitates the user to guide the movement of the annular slide rail 4021, avoiding the effect of misalignment and inability to reset during movement.

[0048] Preferably, to improve the filtration effect, a filter screen plate 422 capable of separating water and sludge is installed inside the water separation chamber 403. A pusher cylinder 423 is fixed on the left side of the water separation chamber 403. The piston rod of the pusher cylinder 423 passes through the water separation chamber 403 and is connected to an arc-shaped pusher plate 424. An output port 425 located above the filter screen plate 422 is provided on the right side of the water separation chamber 403. The pusher cylinder 423 is electrically connected to the control cabinet 10. In order to prevent stones from falling out, a leak-proof ring 426 is fixed on the positioning cover 411. By setting the leak-proof ring 426 above the rotating filter screen 412, leakage can be prevented. To prevent stones from falling off the rotating filter screen 412 during its raising and lowering, one or more inoculation grids 601 are fixed inside the sludge purification tank 6. These grids 601 are later connected to a microbial inoculator to ensure that the sludge and microorganisms are in full contact and mixed evenly, allowing the microorganisms to fully decompose the reacted sludge. The degraded sludge then returns to the river channel through the sewage pipe 420, thus achieving the degradation treatment of the sludge. To prevent water from flowing back into the guide pipe 416, a one-way valve 427 is installed below the guide pipe 416. This one-way valve 427 ensures that water can only flow from the upper end of the guide pipe 416 into the river channel.

[0049] This embodiment also discloses a method for river ecological restoration, including the aforementioned river ecological restoration equipment, characterized by the following specific steps:

[0050] S1. Place the hull 1 in the river channel that needs to be cleaned, and adjust the depth of each water pump 2 in advance according to the depth requirements of the river channel to suck up silt at different depths at the bottom of the river channel.

[0051] S2. Then, the sucked-up sludge is sent into the rotating filter screen 412. At this time, the driving regulating cylinder 421 is working. The regulating cylinder 421 circulates gas into the upper fixed ring 402, which in turn drives the internal annular piston 407 to rotate. The rotation of the annular piston 407 drives the lower gear 408 to rotate, which in turn drives the upper gear 409 to rotate, and finally drives the annular gear 413 to rotate, so as to realize the rotation of the rotating filter screen 412. At the same time, the control cabinet 10 drives the four lifting cylinders 405 to operate at different heights and different process times to ensure that the upper fixed ring 402 swings up and down and rotates in coordination, so as to achieve the effect of filtering sludge and large stones.

[0052] S3. The filtered sludge falls into the water separation chamber 403 through the funnel chamber 404. After water and sludge are separated in the water separation chamber 403, the water flows directly back into the river channel through the guide pipe 416, while the sludge enters the sludge purification tank 6.

[0053] S4. The sludge purification tank 6 is used to make full contact between the sludge and microorganisms, and the microorganisms fully decompose and degrade the sludge after the reaction. The degraded sludge is returned to the river through the sewage pipe 420. At the same time, the undegraded sludge can be sucked out from the sewage outlet 419 by the suction pump later. Later, when there are too many stones on the rotating filter screen 412, the stone cleaning soft manipulator 5 is equipped with a pneumatic gripper 501 to clean and collect the stones on the rotating filter screen 412.

[0054] S5. Using the monitoring cameras 9 on both sides, the ship 1 is monitored in real time for floating garbage on the river surface on both sides. If garbage is detected on the right side of the ship 1, the ultrasonic rangefinder 418 is used to measure the distance between the garbage and the ship 1. The ship 1 is then moved to the vicinity of the garbage. A scooping net is pre-attached to the pneumatic gripper 502, and the garbage cleaning soft robotic arm 8 is driven to work. The garbage is scooped up with the scooping net and poured into the garbage collection pool 7. At the same time, if the monitoring camera 9 on the left side detects garbage on the left side, the garbage on the right side is cleaned up first. Then the ship 1 is rotated and the garbage cleaning soft robotic arm 8 is used to clean up the garbage on the left side in the same way as the right side.

[0055] Preferably, in step S5, the monitoring cameras 9 on both sides detect in real time whether there is floating garbage on the surface of the river on both sides of the hull 1 by pre-creating and storing photos of the river surface without garbage in the control cabinet 10 as reference photos, and then using the monitoring cameras 9 to take photos of the river surface in real time, and then comparing them with the pre-created reference photos to determine whether there is garbage in the river.

[0056] It should be noted that how the control cabinet 10 acquires photos from the monitoring camera 9 and then compares them is conventional technology in the field, and therefore will not be described in detail. Similarly, how the control cabinet 10 acquires the distance signal detected by the ultrasonic rangefinder 418 is also conventional technology in the field, and therefore will not be described in detail. Furthermore, how the ultrasonic rangefinder 418 detects the garbage and the ship's hull is also conventional technology in the field, and therefore will not be described in detail. The aforementioned ultrasonic rangefinder 418, monitoring camera 9, cylinder, control cabinet 10, and other electrical equipment can be directly purchased. Example 2:

[0057] Please refer to Figure 8. The general structure of the river ecological management device provided in this embodiment is the same as that in Embodiment 1. The difference is that, as a preferred embodiment, to improve the water filtration effect, an inclined filter layer 701 is provided in the garbage collection pool 7. By setting the inclined filter layer 701, it is convenient to filter the garbage poured into the garbage collection pool 7 and filter the water to the bottom of the garbage collection pool 7. A drain hole 702 is provided at the bottom of the garbage collection pool 7. By setting the drain hole 702, it is convenient to drain the water discharged from the garbage through the drain hole 702.

8. A method for ecological restoration of rivers, comprising using a river ecological restoration device as described in any one of claims 1-7, characterized in that... The specific steps are as follows: S1. Place the hull (1) in the river channel that needs to be cleaned. Adjust the depth of each water pump (2) according to the depth requirements of the river channel in advance to suck up the silt at different depths at the bottom of the river channel; S2. Then send the sucked silt into the rotating filter screen (412). At this time, the adjusting cylinder (421) is driven to work. At this time, the adjusting cylinder (421) works to circulate gas into the upper fixed ring (402), and then drives the internal ring piston (407) to rotate. At this time, the ring piston (407) rotates and drives the lower gear (408) to rotate, which in turn drives the upper gear (409) to rotate. Finally, the ring gear 2 (413) is driven to rotate, thereby rotating the filter screen (412). At the same time, the control cabinet (10) drives four lifting cylinders (405) to operate at different heights and at different process times to ensure that the upper fixed ring (402) swings up and down and rotates in coordination, thus achieving the function of filtering silt and large stones. S3, the filtered silt falls into the water separation chamber (403) through the funnel chamber (404). After the water and silt are separated in the water separation chamber (403), the water flows directly back into the river through the guide pipe (416), while the silt enters the silt purification tank. 6) Inside, S4, use the sludge purification tank (6) to make the sludge fully contact with microorganisms, and use microorganisms to fully decompose the sludge after the reaction, and degrade and purify the sludge; the degraded sludge is returned to the river through the sewage pipe (420), and the undegraded sludge can be sucked out from the sewage outlet (419) by the suction pump later; later, when there are too many stones on the rotating filter screen (412), the stone cleaning soft manipulator (5) is equipped with a pneumatic gripper (501) to clean and collect the stones on the rotating filter screen (412); S5, use the monitoring cameras (9) on both sides to detect in real time whether the river surface on both sides of the hull (1) is cleaned. If there is floating garbage, and if garbage is detected on the surface of the river on the right side of the hull (1), the distance between the garbage and the hull (1) is measured using an ultrasonic rangefinder (418). Then, the hull (1) is moved to the vicinity of the garbage, and a scooping net is pre-attached to the pneumatic claw clamp (502). The garbage cleaning soft manipulator (8) is driven to work, and the garbage is scooped up using the scooping net and poured into the garbage collection pool (7). At the same time, if the monitoring camera (9) on the left side detects garbage on the left side, the garbage on the right side is cleaned up first, and then the hull (1) is rotated and the garbage cleaning soft manipulator (8) is used to clean up the garbage on the left side in the same way as the right side.

9. A method for ecological restoration of river channels according to claim 8, characterized in that: In step S5, the monitoring cameras (9) on both sides detect whether there is floating garbage on the river surface on both sides of the hull (1) in real time by pre-creating a photo of the river surface without garbage stored in the control cabinet (10) as a reference photo, and then using the monitoring cameras (9) to take a picture of the river surface in real time, and then comparing it with the pre-created reference photo to determine whether there is garbage in the river.
