Description

Technical Field

[0001] This invention belongs to the technical field of high-water-level pipeline dredging devices, specifically a high-water-level pipeline dredging device. Background Technology

[0002] Drainage systems are a crucial component of urban infrastructure. However, due to long-term accumulation and various factors, drainage pipes are frequently clogged with dirt and debris. This not only affects the normal operation of the drainage system but also increases the difficulty of maintenance and repair. Therefore, an effective dredging device is needed to solve this problem.

[0003] Existing dredging equipment typically employs mechanical or chemical methods. Mechanical dredging equipment usually uses high-pressure gas to drive a spray gun, pushing out dirt and debris from inside the pipes. However, the dredging effect of this equipment is not ideal, easily leaving blind spots and residues, and can also cause some damage to the pipes. Chemical dredging equipment uses chemical agents to remove dirt and debris from inside the pipes. Although the effect is better, the use of chemical agents can easily cause environmental pollution, failing to meet environmental protection requirements. Traditional dredging methods usually require manual intervention, which is not only labor-intensive and time-consuming, but also makes it difficult to monitor the siltation situation inside the pipes in real time and take timely countermeasures. Therefore, this invention provides a high-water-level pipe network dredging device. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: A high-water-level pipeline dredging device of the present invention includes a dredging component, a sewage pipe, a vertical shaft, and a drive shaft; the vertical shaft is connected to the sewage pipe, the drive shaft is connected to the vertical shaft, a track plate is fixedly installed on the top of the sewage pipe and the side wall of the vertical shaft, a limit pipe is fixedly installed on the side wall of the track plate, a slider is slidably connected to the track plate and the limit pipe, a dredging component is fixedly connected to the bottom surface of the slider, the dredging component includes a connecting column fixedly installed on the slider, a booster pump is fixedly connected to the bottom surface of the connecting column, a water spray pipe is provided on one side of the booster pump, a water inlet pipe is provided on the side of the booster pump away from the water spray pipe, a propeller is fixedly connected to the bottom surface of the booster pump, and a winding component is provided inside the drive shaft;

[0006] The booster pump is propelled by a thruster to slide along the limiting pipe until it reaches the point where the sludge at the bottom of the sewage pipe needs to be cleaned. Sewage drawn in through the right inlet pipe of the booster pump is then pressurized and sprayed out through the spray pipe, dispersing the sludge at the bottom of the sewage pipe. The dispersed sludge flows downstream under the action of the water flow, reducing debris accumulation in the sewage pipe. Each sewage pipe connecting two adjacent sets of shafts is equipped with a sludge-clearing component. The length of the track plate and the limiting pipe is the same as the length of the sewage pipe between the two sets of shafts, thus allowing for... This device effectively removes sludge from sewage pipes. It boasts a highly efficient sludge removal function, utilizing the power and pressure of water flow to flush away accumulated sediment, ensuring unobstructed pipe flow and preventing sludge buildup. This significantly improves the sludge removal efficiency of long-term high-water-level pipe networks, reducing maintenance costs and manpower input, and meeting environmental and cleanliness requirements. After sludge removal, the device can be retracted into the shaft using a retraction assembly, facilitating maintenance by operators. Furthermore, the sludge removal assembly does not require prolonged immersion in sewage, reducing the likelihood of damage.

[0007] Preferably, a mounting base is fixedly connected to the side wall of the booster pump near the inlet pipe, a wire mesh cover is fixedly connected to the side of the mounting base away from the spray pipe, and a protective plate is fixedly connected to the side of the wire mesh cover away from the mounting base. The wire mesh cover can filter the sewage entering the booster pump, reducing the impact of impurities in the sewage on the operation of the booster pump, while the protective plate can prevent impurities in the water flow from impacting the booster pump, thereby achieving the effect of protecting the booster pump.

[0008] Preferably, a first cleaning ring is slidably connected to the surface of the wire mesh cover, and a set of elastic corrugated tubes are fixedly connected between the first cleaning ring and the protective plate. The protective plate is made of elastic material and has a hollow internal structure. The side of the protective plate away from the first cleaning ring is arc-shaped. A magnetic block is fixedly connected to the center of the inner sidewall of the arc-shaped surface of the protective plate. An electromagnet that is magnetically attracted to the magnetic block is fixedly connected to the inner sidewall of the protective plate near the wire mesh cover. A circular hole communicating with the inside of the corrugated tube is opened on the side of the protective plate near the wire mesh cover. A set of first springs is fixedly connected to the inner wall of the protective plate.

[0009] Because water flows through the wire mesh cover during use, impurities in the water adhere to it. Over time, these accumulated impurities clog the mesh openings, affecting the efficiency of the water inlet pipe. To clean the surface of the wire mesh cover, an electromagnet is activated to attract a magnetic block. This magnetic block moves the curved surface of the protective plate, forcing the air inside the plate through the round holes into the corrugated pipe. The corrugated pipe then expands, pushing the first cleaning ring to scrape away impurities from the wire mesh cover surface, thus achieving automatic self-cleaning.

[0010] Preferably, a first cutting ring is fixedly connected to the side of the cleaning ring away from the bellows. The cleaning ring has a hollow internal structure. A connecting hole communicating with the bellows is opened on the side of the cleaning ring away from the first cutting ring. A sealing plate for sealing the connecting hole is twisted to the inner wall of the bellows corresponding to the first cleaning ring by a torsion spring. A top rod is slidably connected to the side of the first cleaning ring away from the bellows. A connecting line is fixedly connected between the top rod and the sealing plate. A connecting ring is rotatably connected to the side of the mounting base near the wire mesh cover. A second cutting ring is fixedly connected to the side of the connecting ring near the cleaning ring. A set of brush rods made of rigid material is fixedly connected to the inclined surface of the second cutting ring. A set of driving blocks is fixedly connected to the side wall of the connecting ring. One side of the driving block is inclined. An elastic rope is fixedly connected between the driving block and the side wall of the mounting base.

[0011] Some impurities easily get stuck on the wire mesh cover and cannot be completely removed. In this case, when gas is filled into the bellows and it expands, the bellows will expand and push the first cleaning ring (the sealing plate will not be pushed under the resistance of the torsion spring and will continue to seal the connecting hole). During this process, the first and second cutting rings will cooperate to cut off some impurities stuck on the wire mesh cover. When the first and second cutting rings encounter some impurities that are difficult to cut, the first cutting ring cannot continue to move under the push of the connecting ring. At this time, the gas in the bellows will push the sealing plate open and then rush the gas into the connecting ring, so that the gas pushes the push rod. The push rod will push the inclined surface of the drive block, so that the drive block drives the connecting ring to rotate. At this time, the second cutting ring will rotate, thereby allowing the second cutting ring to rotate and cut the impurities, thus improving the cutting effect. At the same time, during the rotation of the second cutting ring, the brush rod can brush the cut impurities and then be carried away by the water flow, preventing the impurities from getting stuck on the first and second cutting rings.

[0012] Preferably, a sliding rod is slidably connected to the side of the protective plate near the water inlet pipe. An inclined paddle is fixedly connected to the surface of the sliding rod inside the wire mesh cover. The end of the sliding rod away from the water outlet pipe is fixedly connected to the inner wall of the arc-shaped surface of the protective plate. When the arc-shaped plate of the protective plate moves the magnetic block, the sliding rod is pushed by the arc-shaped surface. At this time, the sliding rod will drive the paddle to move. The water outlet paddle will push the water to impact the wire mesh cover, thereby knocking away the impurities blocking the mesh and improving the cleaning effect of the wire mesh cover.

[0013] Preferably, a second cleaning ring is slidably connected to the inner wall of the water inlet pipe. A pull rope made of elastic material is fixedly connected between the side of the second cleaning ring away from the slide rod and the inner wall of the water inlet pipe. A pair of brackets are fixedly connected to the side of the second cleaning ring away from the pull rope. A collar is fixedly connected to the end of the bracket away from the second cleaning ring. A fixing rod is fixedly connected to the side of the lever near the collar. An arc-shaped elastic piece is fixedly connected to the other end of the fixing rod. A limit block is fixedly connected to the inner wall of the port of the water inlet pipe.

[0014] When the lever is moved by the slide bar, the elastic plate moves closer to the collar. Then, the two ends of the elastic plate are squeezed through the collar by the inner wall of the collar. Afterwards, when the slide bar moves the lever back to its original position, the elastic plate pulls the collar, causing the collar to move the second cleaning ring to clean the impurities on the inner wall of the water inlet pipe. When the second cleaning ring moves to contact the limit block, the slide bar moves the elastic plate. At this time, the elastic plate will deform under the pull force and disengage from the collar. Then, the second cleaning ring will be reset under the pull of the pull rope. Through the above device, the impurities on the inner wall of the water inlet pipe can be cleaned during the movement of the slide bar.

[0015] Preferably, a limiting ring is fixed at the bottom of the inner cavity of one end of the limiting tube that extends into the sewage pipe, and a piston plate is movably installed in the inner cavity of the limiting tube. The piston plate has an installation hole, and a cable is threaded through the installation hole. The cable passes through both ends of the limiting tube and is connected to a winding assembly. The other end of the cable extends out of the limiting tube and is equipped with a sensing probe.

[0016] By using an induction probe to monitor the sludge situation deep within the sewage pipe, when maintenance is required, the cable is wound up using a retractor assembly to pull the probe out from the depths of the sewage pipe through a limiting tube for maintenance. After maintenance, the induction probe and piston plate are placed back into the limiting tube, and then air is blown into the limiting tube using an external high-pressure air pump. Through the sealing effect between the piston plate and the limiting tube, the induction probe and limiting tube can be blown to the other end of the limiting tube to continue induction monitoring. This induction probe can monitor the sludge accumulation in the sewage pipe in real time, including the degree and location of sludge accumulation, and promptly provide alarm signals to operators to facilitate timely sludge removal from the sewage pipe.

[0017] Preferably, the piston plate has two sets of one-way valve mounting holes, in which one-way valves (not shown in the figure) are installed. Through the one-way valves installed on the one-way valve mounting holes, the piston plate can only transport water from bottom to top. When taking water from deep within the sewage pipe, the water, under the action of water pressure, passes through the one-way valves on the one-way valve mounting holes and moves upwards from the piston plate. Then, the sewage above the piston plate moves towards the end of the limiting pipe located in the vertical shaft by means of the guide pipe, thus realizing the sampling work. With the above device, the sampled sewage can be collected at the wellhead, realizing accurate monitoring of water quality and improving the convenience of sewage sampling.

[0018] Preferably, the winding assembly consists of two sets, each including a motor, a drive shaft, and a winding roller. The motor is located in the drive shaft, and the drive shaft is fixedly installed at the power output end of the motor and extends into the shaft. The drive shaft is connected to the shaft via a sealed bearing. A winding roller is fixedly installed at the end of the drive shaft that extends into the shaft. The two sets of winding assemblies are used to traction and wind up the traction rope and cable, respectively. The motor drives the winding roller to wind up the traction rope, thereby driving the sludge removal assembly back into the shaft. The other motor drives the winding roller to wind up the sensor probe from deep within the sewage pipe through the limiting tube, thus facilitating the removal of the sensor probe and the sludge removal assembly from the sewage pipe.

[0019] Preferably, the connecting ring has a hollow internal structure, and a push ring made of magnetic material is slidably connected inside the connecting ring. A set of inclined air outlets aligned with the brush rod are opened on the side of the connecting ring near the second cutting ring. The first cleaning ring is made of magnetic material that magnetically attracts the push ring. A through hole is opened on the side of the connecting ring away from the air outlet. A second spring is fixedly connected between the side of the push ring near the through hole and the inner wall of the connecting ring. When the first cleaning ring moves closer to the connecting ring, the push ring will magnetically attract the first cleaning ring. At this time, the push ring will push the gas inside the connecting ring, so that the gas is sprayed from the air outlet onto the brush rod, thereby blowing away the impurities on the brush rod and achieving the effect of self-cleaning the brush rod.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The booster pump is propelled by a propeller to slide along the limit pipe until it reaches the point where the sludge at the bottom of the sewage pipe needs to be cleaned. Sewage drawn in through the inlet pipe on the right side of the booster pump is then pressurized and sprayed out through the spray pipe to disperse the sludge at the bottom of the sewage pipe. The dispersed sludge flows downstream under the action of the water flow, reducing the accumulation of debris in the sewage pipe. This device has a highly efficient sludge removal function, which can use the power and pressure of the water flow to flush away the sludge, ensuring the unobstructed flow of the pipeline and preventing sludge from accumulating in the sewage pipe. It can greatly improve the sludge removal efficiency of long-term high-water-level pipe networks, reduce maintenance costs and manpower input, and meet the requirements of environmental protection and cleanliness.

[0022] 2. The wire mesh cover can filter the sewage entering the booster pump, reducing the impact of impurities in the sewage on the operation of the booster pump, while the protective plate can prevent impurities in the water flow from impacting the booster pump, thus achieving the effect of protecting the booster pump.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1: As Figures 1 to 10 As shown in the figure, a high-water-level pipeline dredging device according to an embodiment of the present invention includes a dredging component 9, a sewage pipe 1, a vertical shaft 2, and a drive shaft 3; the vertical shaft 2 is connected to the sewage pipe 1, the drive shaft 3 is connected to the vertical shaft 2, a track plate 5 is fixedly installed on the top of the sewage pipe 1 and the side wall of the vertical shaft 2, a limit pipe 6 is fixedly installed on the side wall of the track plate 5, a slider 8 is slidably connected to the track plate 5 and the limit pipe 6, the dredging component 9 is fixedly connected to the bottom surface of the slider 8, the dredging component 9 includes a connecting column 902 fixedly installed on the slider 8, a booster pump 901 is fixedly connected to the bottom surface of the connecting column 902, a water spray pipe 903 is provided on one side of the booster pump 901, a water inlet pipe 905 is provided on the side of the booster pump 901 away from the water spray pipe 903, a propeller 904 is fixedly connected to the bottom surface of the booster pump 901, and a winding component 4 is provided in the drive shaft 3;

[0038] The booster pump 901 is propelled by the thruster 904 to slide along the limiting pipe 6 until it reaches the point where the sludge at the bottom of the sewage pipe 1 needs to be cleaned. Sewage drawn in through the right inlet pipe 905 of the booster pump 901 is then pressurized by the booster pump 901 and sprayed out through the spray pipe 903 to disperse the sludge at the bottom of the sewage pipe 1. The dispersed sludge flows downstream of the sewage pipe 1 under the action of the water flow, reducing the accumulation of debris in the sewage pipe 1. Each sewage pipe 1 connecting two adjacent sets of vertical shafts 2 is equipped with a sludge-clearing component 9. The length of the track plate 5 and the limiting pipe 6 is the length of the sewage pipe between the two sets of vertical shafts 2. The length of the water pipe 1 allows for effective sludge removal from the sewage pipe 1. This device has a highly efficient sludge removal function, utilizing the power and pressure of water flow to flush away accumulated sediment, ensuring unobstructed pipe flow and preventing sludge buildup in the sewage pipe 1. It can significantly improve the sludge removal efficiency of long-term high-water-level pipe networks, reduce maintenance costs and manpower input, and meet environmental protection and cleanliness requirements. After sludge removal, the sludge removal assembly 9 can be retracted into the vertical shaft 2 using the retraction assembly 4, which facilitates maintenance by operators. Furthermore, the sludge removal assembly 9 does not need to be immersed in sewage for extended periods, reducing the possibility of damage to the sludge removal assembly 9.

[0039] A mounting base 25 is fixedly connected to the side wall of the booster pump 901 near the inlet pipe 905. A wire mesh cover 906 is fixedly connected to the side of the mounting base 25 away from the spray pipe 903. A protective plate 907 is fixedly connected to the side of the wire mesh cover 906 away from the mounting base 25. The wire mesh cover 906 can filter the sewage entering the booster pump 901, reducing the impact of impurities in the sewage on the operation of the booster pump 901. The protective plate 907 can prevent impurities in the water flow from impacting the booster pump 901, thereby achieving the effect of protecting the booster pump 901.

[0040] A first cleaning ring 10 is slidably connected to the surface of the wire mesh cover 906. A set of elastic corrugated tubes 11 are fixedly connected between the first cleaning ring 10 and the protective plate 907. The protective plate 907 is made of elastic material and has a hollow internal structure. The side of the protective plate 907 away from the first cleaning ring 10 is arc-shaped. A magnetic block 12 is fixedly connected to the center of the inner sidewall of the arc-shaped surface of the protective plate 907. An electromagnet 13 that is magnetically attracted to the magnetic block 12 is fixedly connected to the inner sidewall of the protective plate 907 near the wire mesh cover 906. A round hole communicating with the inside of the corrugated tubes 11 is opened on the side of the protective plate 907 near the wire mesh cover 906. A set of first springs 14 are fixedly connected to the inner wall of the protective plate 907.

[0041] Since water flows through the wire mesh cover 906 during use, impurities in the water will adhere to the wire mesh cover 906. The longer the wire mesh cover 906 is used, the more impurities accumulate and clog the mesh, thus affecting the efficiency of water pumping by the inlet pipe 905. When it is necessary to clean the impurities on the surface of the wire mesh cover 906, the electromagnet 13 can be activated to attract the magnetic block 12. At this time, the magnetic block 12 will drive the arc-shaped surface of the protective plate 907 to move, so that the arc-shaped surface squeezes the gas inside the protective plate 907 into the bellows 11 through the round hole. At this time, the bellows 11 will expand and push the first cleaning ring 10, so that the first cleaning ring 10 scrapes off the impurities on the surface of the wire mesh cover 906, thereby achieving the effect of automatic self-cleaning of impurities on the wire mesh cover 906.

[0042] The cleaning ring is fixedly connected to a first cutting ring 19 on the side away from the bellows 11. The cleaning ring has a hollow structure inside. A connecting hole 15 communicating with the bellows 11 is opened on the side of the cleaning ring away from the first cutting ring 19. A sealing plate 16 for sealing the connecting hole 15 is twisted to the inner wall of the first cleaning ring 10 corresponding to the bellows 11 by a torsion spring. A top rod 17 is slidably connected to the side of the first cleaning ring 10 away from the bellows 11. A connecting line 18 is fixedly connected between the top rod 17 and the sealing plate 16. A connecting ring 20 is rotatably connected to the side of the mounting base 25 near the wire mesh cover 906. A second cutting ring 21 is fixedly connected to the side of the connecting ring 20 near the cleaning ring. A set of brush rods 22 made of rigid material is fixedly connected to the inclined surface of the second cutting ring 21. A set of driving blocks 24 is fixedly connected to the side wall of the connecting ring 20. One side of the driving block 24 is inclined. An elastic rope 23 is fixedly connected between the driving block 24 and the side wall of the mounting base 25.

[0043] Some impurities easily get stuck on the wire mesh cover 906, making it impossible to completely remove them. In this case, when gas is introduced into the bellows 11 for expansion, the bellows 11 expands and pushes the first cleaning ring 10 (the sealing plate 16, under the resistance of the torsion spring, will not be pushed and will continue to seal the connecting hole 15). During this process, the first cutting ring 19 and the second cutting ring 21 cooperate to cut off some impurities stuck on the wire mesh cover 906. When the first cutting ring 19 and the second cutting ring 21 encounter some impurities that are difficult to cut off, the first cutting ring 19 cannot continue to be pushed by the connecting ring 20. As the bellows moves downwards, the gas inside the bellows 11 pushes open the sealing plate 16 and then rushes into the connecting ring 20, causing the gas to push the push rod 17. The push rod 17 then pushes the inclined surface of the drive block 24, causing the drive block 24 to drive the connecting ring 20 to rotate. At this time, the second cutting ring 21 will rotate, thereby allowing the second cutting ring 21 to rotate and cut the impurities, thus improving the cutting effect on the impurities. At the same time, during the rotation of the second cutting ring 21, the brush rod 22 can brush the cut impurities and then carry them away by the water flow, preventing the impurities from sticking on the first cutting ring 19 and the second cutting ring 21.

[0044] A sliding rod 27 is slidably connected to the side of the protective plate 907 near the water inlet pipe 905. An inclined paddle 26 is fixedly connected to the surface of the sliding rod 27 inside the wire mesh cover 906. The end of the sliding rod 27 away from the water outlet pipe is fixedly connected to the inner wall of the arc-shaped surface of the protective plate 907. When the arc-shaped plate of the protective plate 907 moves the magnetic block 12, the sliding rod 27 is pushed by the arc-shaped surface. At this time, the sliding rod 27 will drive the paddle 26 to move. The water outlet paddle 26 will push the water to impact the wire mesh cover 906, thereby knocking away the impurities blocking the mesh and improving the cleaning effect of the wire mesh cover 906.

[0045] A second cleaning ring 28 is slidably connected to the inner wall of the water inlet pipe 905. A pull rope 29 made of elastic material is fixedly connected between the side of the second cleaning ring 28 away from the slide rod 27 and the inner wall of the water inlet pipe 905. A pair of brackets 30 are fixedly connected to the side of the second cleaning ring 28 away from the pull rope 29. A collar 31 is fixedly connected to the end of the bracket 30 away from the second cleaning ring 28. A fixing rod 32 is fixedly connected to the side of the paddle 26 near the collar 31. An arc-shaped elastic piece 33 is fixedly connected to the other end of the fixing rod 32. A limit block 37 is fixedly connected to the inner wall of the port of the water inlet pipe 905.

[0046] When the lever 26 is moved by the slide bar 27, the elastic plate 33 moves closer to the collar 31. Then, the two ends of the elastic plate 33 are squeezed through the inner wall of the collar 31. Afterwards, when the slide bar 27 moves the lever 26 to reset, the elastic plate 33 pulls the collar 31, causing the collar 31 to drive the second cleaning ring 28 to clean the impurities on the inner wall of the water inlet pipe 905. When the second cleaning ring 28 moves to contact the limit block 37, the slide bar 27 moves the elastic plate 33. At this time, the elastic plate 33 will deform under the pull force and disengage from the collar 31. Then, the second cleaning ring 28 will reset under the pull of the pull rope 29. Through the above device, the impurities on the inner wall of the water inlet pipe 905 can be cleaned during the movement of the slide bar 27.

[0047] A limiting ring 603 is fixed at the bottom of the inner cavity of one end of the limiting tube 6 that extends into the sewage pipe 1, and a piston plate 602 is movably installed in the inner cavity of the limiting tube 6. The piston plate 602 has an installation hole 6022, and a cable 601 is threaded through the installation hole 6022. The cable 601 passes through both ends of the limiting tube 6 and is connected to the winding assembly 4. The other end of the cable 601 extends out of the limiting tube 6 and is equipped with a sensing probe 604.

[0048] By using the sensor probe 604 to monitor the sludge condition deep within the sewage pipe 1, when maintenance is required on the sensor probe 604, the cable rope 601 is wound up using the winding assembly 4 to pull the sensor probe 604 out from the depths of the sewage pipe 1 through the limiting tube 6 for maintenance. After maintenance, the sensor probe 604 and piston plate 602 are placed back into the limiting tube 6, and then air is blown into the limiting tube 6 by an external high-pressure air pump. Through the sealing effect between the piston plate 602 and the limiting tube 6, the sensor probe 604 and the limiting tube 6 can be blown to the other end of the limiting tube 6 to continue the sensing and monitoring work. Through the sensor probe 604, the sludge condition in the sewage pipe 1 can be monitored in real time, including the degree and location of sludge, and alarm signals can be provided to the operators in a timely manner to carry out sludge removal work in the sewage pipe 1.

[0049] The piston plate 602 has two sets of one-way valve mounting holes 6021, in which one-way valves (not shown in the figure) are installed. Through the one-way valves installed in the one-way valve mounting holes 6021, the piston plate 602 can only transport water from bottom to top. When water is drawn from the depth of the sewage pipe 1, the water is pushed upwards from the piston plate 602 by the water pressure through the one-way valves in the one-way valve mounting holes 6021. Then, the sewage above the piston plate 602 moves towards the end of the limiting pipe 6 located in the vertical shaft 2 by means of the guide pipe, thus realizing the sampling work. The above device can collect the sampled sewage at the wellhead, realize accurate monitoring of water quality, and improve the convenience of sewage sampling.

[0050] The winding assembly 4 consists of two sets, each including a motor 401, a drive shaft 402, and a take-up roller 403. The motor 401 is installed in the drive well 3, and the drive shaft 402 is fixedly installed at the power output end of the motor 401 and extends into the vertical shaft 2. The drive shaft 402 and the vertical shaft 2 are connected by a sealed bearing. The take-up roller 403 is fixedly installed at one end of the drive shaft 402 that extends into the vertical shaft 2. The two sets of winding assemblies 4 are used to pull and wind up the traction rope 7 and the cable 601, respectively. The motor 401 drives the take-up roller 403 to wind up the traction rope 7, thereby driving the sludge removal assembly 9 back into the vertical shaft 2. The other motor 401 drives the take-up roller 403 to perform the winding operation, so that the sensing probe 604 passes through the limiting tube 6 from the depth of the sewage pipe 1, thereby achieving the effect of conveniently removing the sensing probe 604 and the sludge removal assembly 9 from the sewage pipe 1.

[0051] Example 2: Figure 11 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the connecting ring 20 has a hollow internal structure, and a push ring 34 made of magnetic material is slidably connected inside the connecting ring 20. A set of air outlets 36 with an inclination aligned with the brush rod 22 are opened on the side of the connecting ring 20 near the second cutting ring 21. The first cleaning ring 10 is made of magnetic material that magnetically attracts the push ring 34. A through hole 35 is opened on the side of the connecting ring 20 away from the air outlet 36. A second spring is fixedly connected between the side of the push ring 34 near the through hole 35 and the inner wall of the connecting ring 20. When the first cleaning ring 10 moves closer to the connecting ring 20, the push ring 34 will magnetically attract the first cleaning ring 10. At this time, the push ring 34 will push the gas inside the connecting ring 20, so that the gas is sprayed from the air outlet 36 onto the brush rod 22, thereby blowing away the impurities on the brush rod 22 and achieving the effect of self-cleaning the brush rod 22.

[0052] Working principle: The booster pump 901 is propelled by the propeller 904 to slide along the limiting pipe 6 until it reaches the point where the sludge at the bottom of the sewage pipe 1 needs to be cleaned. Sewage drawn in through the right inlet pipe 905 of the booster pump 901 is then pressurized by the booster pump 901 and sprayed out through the spray pipe 903, dispersing the sludge at the bottom of the sewage pipe 1. The dispersed sludge flows downstream of the sewage pipe 1 under the action of the water flow, reducing the accumulation of debris in the sewage pipe 1. Each sewage pipe 1 connecting two adjacent sets of vertical shafts 2 is equipped with a sludge-clearing component 9. The length of the track plate 5 and the limiting pipe 6 is the length of the sewage pipe 1 between the two sets of vertical shafts 2. This effectively removes sludge from the sewage pipe 1, making the device highly efficient in sludge removal. The power and pressure of water flow can be used to flush away silt, ensuring the smooth flow of the pipeline and preventing silt from accumulating in the sewage pipe 1. This can greatly improve the sludge removal efficiency of long-term high-water-level pipe networks, reduce maintenance costs and manpower input. After sludge removal, the sludge removal assembly 9 can be retracted into the vertical shaft 2 using the retraction assembly 4. This makes it easier for operators to maintain the assembly, and the sludge removal assembly 9 does not need to be immersed in sewage for a long time, reducing the possibility of damage to the assembly 9. The wire mesh cover 906 can filter the sewage entering the booster pump 901, reducing the impact of impurities in the sewage on the operation of the booster pump 901. The protective plate 907 can prevent impurities in the water flow from impacting the booster pump 901, thus achieving the effect of protecting the booster pump 901.

[0053] Because water flows through the wire mesh cover 906 during use, impurities in the water will adhere to it. The longer the wire mesh cover 906 is used, the more impurities accumulate, clogging the mesh and affecting the pumping efficiency of the inlet pipe 905. To clean the impurities from the surface of the wire mesh cover 906, the electromagnet 13 can be activated to attract the magnetic block 12. The magnetic block 12 will then move the arc-shaped surface of the protective plate 907, causing the arc-shaped surface to press against the protective plate 907. Gas enters the bellows 11 through the round hole. The bellows 11 then expands, pushing the first cleaning ring 10 to scrape away impurities on the surface of the wire mesh cover 906, thus achieving automatic self-cleaning of impurities on the wire mesh cover 906. Some impurities tend to stick to the wire mesh cover 906 and cannot be completely removed. In this case, gas can be introduced into the bellows 11 for expansion, causing the bellows 11 to expand and push the first cleaning ring 10. Ring 10 (the sealing plate 16 will not be pushed under the resistance of the torsion spring and will continue to seal the connecting hole 15). During this process, the first cutting ring 19 and the second cutting ring 21 will cooperate to cut off some impurities hanging on the wire mesh cover 906. When the first cutting ring 19 and the second cutting ring 21 encounter some impurities that are difficult to cut, the first cutting ring 19 cannot continue to move under the push of the connecting ring 20. At this time, the gas in the bellows 11 will push the sealing plate 16 open and then rush the gas into the connecting ring 20, so that the gas pushes the push rod 17. At this time, the push rod 17 will push the inclined surface of the drive block 24, so that the drive block 24 will drive the connecting ring 20 to rotate. At this time, the second cutting ring 21 will rotate, so that the second cutting ring 21 will rotate and cut the impurities, thereby improving the cutting effect of the impurities. At the same time, during the rotation of the second cutting ring 21, the brush rod 22 can brush the cut impurities and then be carried by the water flow to prevent the impurities from hanging on the first cutting ring 19 and the second cutting ring 21.

[0054] When the arc-shaped plate of the protective plate 907 moves the magnetic block 12, the slide rod 27 is pushed by the arc surface. At this time, the slide rod 27 will drive the paddle 26 to move. The water-discharging paddle 26 will push the water to impact the wire mesh cover 906, thereby knocking away the impurities blocking the mesh and improving the cleaning effect of the wire mesh cover 906. When the paddle 26 is driven by the slide rod 27 to move, the elastic piece 33 will move closer to the collar 31. Then, the two ends of the elastic piece 33 will be squeezed through the inner wall of the collar 31 and then the slide rod 27 will move the elastic piece 33 closer to the collar 31. When the movable lever 26 is reset, the elastic plate 33 will pull the collar 31, causing the collar 31 to drive the second cleaning ring 28 to clean the impurities on the inner wall of the water inlet pipe 905. When the second cleaning ring 28 moves to contact the limit block 37, the slide rod 27 will drive the elastic plate 33 to move. At this time, the elastic plate 33 will deform under the action of the pulling force and disengage from the collar 31. Then the second cleaning ring 28 will be reset under the pull of the pull rope 29. Through the above device, the impurities on the inner wall of the water inlet pipe 905 can be cleaned during the movement of the slide rod 27.

[0055] By using the sensor probe 604 to monitor the sludge condition deep within the sewage pipe 1, when maintenance is required on the sensor probe 604, the cable rope 601 is wound up using the winding assembly 4 to pull the sensor probe 604 out from the depths of the sewage pipe 1 through the limiting tube 6 for maintenance. After maintenance, the sensor probe 604 and piston plate 602 are placed into the limiting tube 6, and then air is blown into the limiting tube 6 by an external high-pressure air pump. Through the sealing effect between the piston plate 602 and the limiting tube 6, the sensor probe 604 and the limiting tube 6 can be blown to the other end of the limiting tube 6 to continue the sensing and monitoring work. Through the sensor probe 604, the sludge condition in the sewage pipe 1 can be monitored in real time, including the degree and location of sludge, and alarm signals can be provided to the operators in a timely manner to carry out sludge removal work in the sewage pipe 1.

[0056] By using a one-way valve installed on the one-way valve plate mounting hole 6021, the piston plate 602 can only transport water from bottom to top. When taking water from the depth of the sewage pipe 1, the water, under the action of water pressure, passes through the one-way valve on the one-way valve plate mounting hole 6021 and moves upward to the piston plate 602. Then, the sewage above the piston plate 602 moves towards the end of the limiting pipe 6 located in the vertical shaft 2 to achieve the sampling work. With the above device, the sampled sewage can be collected at the wellhead, achieving accurate monitoring of water quality and improving the convenience of sewage sampling.

[0057] The motor 401 drives the take-up roller 403 to wind up the traction rope 7, which in turn drives the sludge removal component 9 back into the vertical shaft 2. Another motor 401 drives the take-up roller 403 to wind up the rope, which pulls the sensor 604 from deep inside the sewage pipe 1 through the limiting pipe 6, thereby facilitating the removal of the sensor 604 and the sludge removal component 9 from the sewage pipe 1.
