Description

Technical Field

[0001] This invention relates to the field of vertical sewage pump technology, specifically to a vertical water pump dredging device. Background Technology

[0002] As a core fluid transport equipment in municipal water supply and drainage, industrial wastewater treatment, mine sewage discharge, and agricultural irrigation, vertical water pumps have always faced the key technical bottleneck of clogging of their flow-through components during long-term operation under conditions of high sand content, many impurities, and easy scaling. Existing solutions for water pump sludge removal are mainly divided into two categories. One category is water pump equipment with automatic sludge removal function, as disclosed in the prior art CN219119531U. After monitoring the flow rate with an electromagnetic flow meter, the propeller is controlled to rotate in reverse to achieve backwashing, and a scraper is used to scrape the filter screen in one direction to remove sludge. Another type is the vertical water pump dredging equipment disclosed in the prior art CN222376823U, which uses a suspended clamping and high-frequency vibration method to shake off the residual material inside the water pump from the filter screen to complete the dredging. In addition, traditional vertical water pumps generally adopt methods such as manual dredging by dismantling after shutdown and single constant pressure backflushing dredging. Although these methods can alleviate the clogging problem to some extent, they still have many technical defects and cannot adapt to the actual working conditions of continuous operation of vertical water pumps. Specifically, the dredging and pumping operations of existing vertical water pumps and dredging-related equipment cannot be carried out simultaneously. Both need to be shut down to complete dredging and maintenance, which limits the continuous operation time of the water pump. Moreover, shutdown for dismantling and maintenance will also cause a series of subsequent working conditions problems. Based on this, the present invention provides a vertical water pump dredging device to solve the problems mentioned in the background art. Summary of the Invention

[0015] The beneficial effects of this invention are: 1. This invention solves the problem of the inability to synchronize dredging and pumping operations in existing technologies. By symmetrically setting up two workstations for pumping liquid and dredging inside the outer valve ring, and combining them with a parallel structure of double pump casings fixedly connected to the workstation frame, it achieves synchronous and uninterrupted operation of vertical water pumps for sewage pumping, online dredging of filter elements, and self-cleaning of the pump casing. The 180° precise switching of the workstation frame can be completed in milliseconds. With the intelligent monitoring and closed-loop control of the feedback unit, it can automatically complete the workstation interchange of the double pump casings according to the actual clogging status of the water pump. This allows the pump casing to be maintained to enter the dredging workstation in a timely manner to complete the entire process of maintenance, while the clean pump casing continues to perform water delivery operations in the pumping workstation. From a structural design perspective, this invention breaks through the technical bottleneck of mutual exclusion between dredging and pumping in existing technologies, and improves the continuous running time and long-term operational stability of vertical water pumps.

[0016] 2. This invention constructs a comprehensive, multi-faceted, and collaborative sludge-cleaning system. Compared to existing technologies that rely on single-directional scraping, constant-pressure backflushing, or high-frequency vibration sludge-cleaning methods, it achieves a qualitative improvement in sludge-cleaning effectiveness. Furthermore, the various sludge-cleaning self-cleaning methods form a highly synergistic effect. Specifically, this invention integrates five core maintenance methods: differential reverse circumferential scraping, alternating bidirectional rubbing, filter element axial amplitude vibration, backflushing pipe pulse-type high-pressure water backflushing, and impeller axial reciprocating self-cleaning. At the sludge-cleaning station, the power unit drives the filter element and brush cylinder to rotate alternately at different speeds, while simultaneously causing the filter element to undergo axial periodic amplitude vibration. This results in the spiral brush blades performing a composite scraping action on the filter element, combining circumferential bidirectional rubbing with axial gradient amplitude reciprocating rubbing, in conjunction with backflushing. The high-pressure pulsed water jet washes back from the inside of the filter element, effectively removing caked sludge, tangled fibers, and deep-seated impurities from the filter pores. Simultaneously, the power unit drives the transverse vibrating frame to move the impeller along the pump casing axis in a gradient amplitude reciprocating motion, achieving thorough self-cleaning of the pump casing's inner wall corners, fitting gaps, and dead water zones. The frequency and stroke amplitude of each maintenance method are precisely matched through the power unit's precise transmission. Sludge removal and pump self-cleaning are carried out simultaneously and in synergy, solving the problems of incomplete sludge removal and the ability to remove only shallow impurities in existing technologies. It also simultaneously solves the problems of reduced pumping efficiency and corrosion and wear of flow components caused by sludge accumulation inside the pump casing, maintaining high pumping efficiency and high filtration accuracy for a long time.

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0020] The present invention provides the following preferred embodiments. like Figure 1-11 As shown, a vertical water pump dredging device includes an outer valve ring 1 and a station frame 2 rotatably connected therein. A pumping station and a dredging station are symmetrically arranged on the inner side of the outer valve ring 1, and the pumping station and the dredging station are offset by 180°. The device also includes: Both pump housings 3 are fixedly connected to the station rotating frame 2, and each pump housing 3 is equipped with a pumping unit. The pumping unit includes a filter chamber 31, a hollow shaft 32 rotatably connected to the pump casing 3, a horizontal vibrating frame 33 and a vertical vibrating frame 34 slidably connected to the pump casing 3, and a pump shaft 35 rotatably connected to the horizontal vibrating frame 33, and the pump shaft 35 is connected to the hollow shaft 32 in a transmission connection. An impeller 36 is fixedly mounted on the pump shaft 35 at a position corresponding to the inner side of the pump casing 3. A hollow vortex 37 is rotatably connected to the bottom port of the pump casing 3. A filter element 38 is rotatably connected to the vertical vibrating frame 34. The axis of pump housing 3 is perpendicular to the axis of filter element 38; The filter element 38 is connected to the hollow swirl cylinder 37. A brush cylinder 39 is rotatably sleeved on the filter element 38. The brush cylinder 39 is sealed and fitted with the water filter chamber cylinder 31. A spiral brush blade 310 that fits with the filter element 38 is installed on the bottom surface of the brush cylinder 39. In this embodiment, the filter element 38 is made of stainless steel, the spiral brush blade 310 is made of polyurethane elastomer, the filter element 38 is evenly distributed with filter holes, the filter holes are conical holes, the inner diameter of the filter hole is 1.2mm, the outer diameter is 0.8mm, the hole spacing is 2.5mm, the filter element 38 is an integral cylindrical hollow structure, the bottom of the filter element 38 is closed, the top is open, the nominal outer radius of the filter element 38 is 120mm, the inner radius is 90mm, and the effective filtration height of the filter element 38 is 360mm; The spiral brush 310 has a constant pitch structure, with the pitch being consistent with the effective filtration height of the filter element 38. The spiral angle is 15°. The spiral brush 310 axially covers the entire effective filtration height of the filter element 38, ensuring that a single rotation can complete the scraping of the entire surface of the filter element 38 without dead angles. The interference fit between the spiral brush blade 310 and the filter element 38 is 0.35 mm; The power unit is used to drive the pump shaft 35 and filter element 38 to rotate in a directional differential speed at the pumping station, and to drive the pump shaft 35 and filter element 38 to rotate alternately in the forward and reverse directions at the dredging station. At the same time, it drives the horizontal vibrating frame 33 to vibrate periodically in the horizontal direction and the vertical vibrating frame 34 to vibrate periodically in the vertical direction. When the equipment is running, the two pump casings 3 correspond to the pumping station and the sludge removal station respectively with the station rotating frame 2, realizing the parallel and uninterrupted operation of sewage pumping and filter element 38 sludge removal and pump body self-cleaning. At the pumping station, the power unit drives the hollow swirl cylinder 37 to rotate the filter element 38 along its own axis. At the same time, through the meshing transmission of the synchronous shaft 317, the synchronous bevel gear and the fourth bevel gear, the brush cylinder 39 and the filter element 38 rotate in opposite directions at a different speed. The spiral brush blades 310 continuously scrape the outer surface of the filter element 38, simultaneously completing the filtration of sewage and the initial cleaning of the surface of the filter element 38. At this station, the horizontal vibration frame 33 and the vertical vibration frame 34 remain relatively stationary. The pump shaft 35 rotates stably with the hollow shaft 32, driving the impeller 36 to continuously pump at constant pressure. The clean water filtered by the filter element 38 is pressurized and transported by the pump casing 3 to the clean water discharge pipe 11, completing the core water delivery operation of the vertical water pump. At the dredging station, the power unit automatically switches drive modes. On one hand, it drives the hollow rotary drum 37 and filter element 38 to rotate at different speeds in alternating directions, simultaneously driving the brush cylinder 39 and filter element 38 to rotate at different speeds in opposite directions. This causes the spiral brush blades 310 to perform bidirectional circumferential reciprocating scraping motions on the surface of the filter element 38, preventing sludge from directionally accumulating along the spiral grooves and forming dead corners in dredging due to unidirectional rotation. On the other hand, it simultaneously drives the vertical vibration frame 34 to cause the filter element 38 and brush cylinder 39 to perform periodic up-and-down amplitude vibrations along the axis of the filter element 38, causing the spiral brush blades 310 to interact with the surface of the filter element 38. The surface forms an axial reciprocating rubbing motion, which is adapted to the spiral rise angle of the spiral brush blade 310 to achieve a full-height surface of the filter element 38 without dead angles. At the same time, the horizontal vibration frame 33 drives the pump shaft 35 to slide back and forth along the axis of the pump casing 3. The pump shaft 35 synchronously drives the impeller 36 to complete the full-stroke axial reciprocating motion inside the pump casing 3, continuously scraping the accumulated sludge at the corners of the inner wall of the pump casing 3 and the gap between the impeller 36 and the pump casing 3. This achieves a self-cleaning process without dead angles in the internal flow channel of the pump casing 3, avoids the long-term accumulation and hardening of sludge in the dead water area and the gap of the pump casing 3, and ensures the long-term stable pumping efficiency of the impeller 36. During this process, the backwash pipe 12 connected to the water purification pipe 11 simultaneously supplies pulsed high-pressure purified water. The high-pressure purified water flushes from the inside to the outside of the filter element 38 in the opposite direction. Combined with the alternating rotation and axial amplitude vibration of the filter element 38, it impacts and peels off the deep-seated impurities in the filter holes. The above-mentioned structural design breaks through the limitations of traditional water pump cleaning equipment, which can only clean the filter element 38, cannot simultaneously achieve self-cleaning inside the pump body, and must be shut down and disassembled to complete the cleaning operation. Through the parallel design of pumping and cleaning in two stations, it realizes the synchronous and uninterrupted operation of sewage pumping and filtration, online cleaning and regeneration of filter element 38, and self-cleaning inside pump casing 3. The entire process maintenance of the core flow components of the water pump can be completed without stopping the machine, improving the continuous running time and long-term operational stability of the vertical water pump. Simultaneously, through the dual-mode drive design of directional differential rotation and alternating directional differential rotation, combined with the axial amplitude vibration of filter element 38, the axial reciprocating self-cleaning of impeller 36, and the pulse-type high-pressure water backwashing of backwash pipe 12, a full-dimensional sludge cleaning and maintenance system is constructed, which includes circumferential bidirectional scraping, axial contact rubbing, pulse-type high-pressure water backwashing, and pump body dead corner self-cleaning. This not only solves the problems of sludge buildup on the surface of filter element 38, fiber entanglement, and deep blockage of filter pores, but also simultaneously achieves dead-angle-free self-cleaning of the internal flow channel of pump casing 3, avoiding the problems of pumping efficiency reduction and corrosion and wear of flow parts caused by sludge accumulation in pump casing 3, and improving the performance of the equipment throughout its entire life cycle. The inner valve cylinder 4 is rotatably connected to the inner side of the outer valve ring 1. The top ports of the two pump housings 3 are fixedly connected to the inner valve cylinder 4. The inner valve cylinder 4 is coaxially fixedly connected to the station rotating frame 2 and rotates synchronously with the station rotating frame 2. In this embodiment, the inner valve cylinder 4 is provided with two coaxially arranged connection interfaces. The two connection interfaces are respectively connected to the liquid outlet ends of the two pump housings 3. The axis of the connection interface is parallel to the axis of the pump housing 3 and perpendicular to the axis of the outer valve ring 1. The port of the connection interface is provided with a first sealing ring that fits against the outer valve ring 1, and the first sealing ring is coaxially arranged with the connection interface; Two second sealing rings are fixedly installed on the outer wall of the inner valve cylinder 4. The second sealing rings are coaxially arranged with the inner valve cylinder 4. Both second sealing rings are sealed and fitted with the outer valve ring 1 to ensure the sealing of the connection between the outer valve ring 1 and the inner valve cylinder 4. The two second sealing rings are respectively arranged on the upper and lower sides of the connection interface. Specifically, the inner valve cylinder 4 is coaxially rotatably installed inside the outer valve ring 1 and is coaxially fixedly connected to the station rotating frame 2, rotating synchronously with the station rotating frame 2; A clean water drain pipe 11 is connected to the outer valve ring 1 at the position corresponding to the pumping station, and a backflushing pipe 12 is connected to the position corresponding to the sludge removal station. The liquid inlet port of the backflushing pipe 12 is connected to the clean water drain pipe 11. The liquid preparation mechanism is used to pump sewage into the filter chamber 31 at the pumping station and discharge the backwash sewage discharged from the filter chamber 31 at the sludge removal station. The liquid mixing mechanism includes a mounting bracket 5, which is fixedly connected to the outer valve ring 1. A liquid dispensing cylinder 41 is fixedly mounted on the mounting bracket 5. The liquid dispensing cylinder 41 has a sewage discharge chamber 42 and a water inlet chamber 43 that are isolated from each other from the outside to the inside. A first valve hole 44 is provided on the liquid separator 41 at the position corresponding to the pumping station, and a second valve hole 45 is provided at the position corresponding to the sludge removal station. The first valve hole 44 is connected to the water inlet chamber 43, and the second valve hole 45 is connected to the sewage discharge chamber 42. A sewage discharge valve 46 is connected to the sewage discharge chamber 42, and a sewage inlet pipe 47 is connected to the water inlet chamber 43. In this embodiment, the ports of the clean water drain pipe 11, the sewage inlet pipe 47 and the drain valve 46 are all provided with flange interfaces, and the flange interfaces on the clean water drain pipe 11 and the sewage inlet pipe 47 are arranged coaxially. Both the backflush pipe 12 and the clean water drain pipe 11 are equipped with electromagnetic control valves; In this embodiment, the electromagnetic control valve of the recoil tube 12 is a high-speed switching electromagnetic valve, and the microcontroller 6 outputs a PWM signal to control its on and off, with the on and off frequency set to 5Hz. A liquid distribution valve ring 48 is rotatably sleeved on the liquid distribution cylinder 41, and a rotary sealing ring is provided between the liquid distribution valve ring 48 and the liquid distribution cylinder 41. At the position corresponding to the first valve hole 44, the two water filter chambers 31 are connected to the liquid distribution valve ring 48 by a first branch pipe 49, and the first branch pipe 49 is arranged parallel to the valve hole. The bottom ends of the two filter chambers 31 are connected to the second branch pipes 50. At the position corresponding to the second valve hole 45, the other end of the two second branch pipes 50 is connected to the liquid distribution valve ring 48. The liquid distribution valve ring 48 is provided with a liquid distribution interface that is connected to the second branch pipes 50. The liquid distribution interface is set parallel to the second valve hole 45. When the equipment is running, the liquid separator 41 is fixed relative to the outer valve ring 1 by the mounting bracket 5. The pump casing 3, which rotates with the station rotating frame 2, has its matching first branch pipe 49 and second branch pipe 50 rotating synchronously with the liquid distribution valve ring 48 to realize the automatic adaptation and opening and closing of the inlet and outlet flow channels. When the pump casing 3 is in the pumping position, the first branch pipe 49 is aligned and connected with the first valve hole 44 through the liquid distribution valve ring 48. The sewage to be treated introduced by the sewage inlet pipe 47 enters the filter chamber 31 through the inlet chamber 43, the first valve hole 44, and the first branch pipe 49. After being filtered by the filter element 38, the clean water is pressurized by the pump casing 3 and transported to the clean water outlet pipe 11 to complete the pumping operation. When the pump casing 3 rotates to the sludge removal station, the liquid distribution valve ring 48, which rotates synchronously with the station rotating frame 2, causes the second branch pipe 50 corresponding to the pump casing to automatically align with the second valve hole 45 on the liquid distribution cylinder 41, opening the sewage discharge channel. The backwash sewage generated by the pulse high-pressure clean water of the backwash pipe 12 backwashes the filter element 38, along with the sludge on the inner wall of the pump casing 3 scraped off by the impeller 36, flows through the second branch pipe 50, the liquid distribution valve ring 48, and the second valve hole 45 into the sewage discharge chamber 42 connected to the second valve hole, and is finally discharged from the equipment by the sewage discharge valve 46. The sewage discharge chamber 42 and the water inlet chamber 43 are isolated from each other, ensuring that there is no risk of cross-contamination between the sewage discharge and water purification processes. The sealed cavity structure can be perfectly adapted to the pulse backwash water flow, ensuring stable discharge of sewage without leakage. No additional solenoid valve is required to control the flow channel switching throughout the process. The rotational adaptation of valve ring 48 enables automatic switching of the entire flow channel during sewage inlet, purified water pumping, and backwash discharge. This eliminates the need for additional multi-channel solenoid valves to control the flow channel opening and closing, simplifying the fluid control system, avoiding cross-flow and mixing issues in multiple channels, and ensuring complete isolation between the filtration and purification process and the backwash discharge process. Meanwhile, through the dual-branch diversion design of the first branch pipe 49 and the second branch pipe 50, the independent flow channel design of the forward liquid inlet of the pumping station and the reverse sewage discharge of the sludge removal station is realized, which avoids the problem of secondary pollution of water purification by residual sludge caused by alternating liquid inlet and outlet in the same flow channel, and improves the water purification accuracy of the equipment. In addition, the double-chamber sealed structure can perfectly adapt to the pulse backwash water flow of the backwash pipe 12, stably supporting the pulse sewage discharge and the centralized discharge of self-cleaning sludge from the pump casing 3, without the risk of sewage backflow or leakage. At the same time, the liquid separator 41 and the outer valve ring 1 adopt an integrated fixed design, and the inlet, outlet, and sewage discharge interfaces are all integrated into the same valve body structure, reducing the overall installation volume of the equipment and adapting to the narrow installation space of the vertical water pump. The coaxial design of the flange interfaces of each port can be directly connected to the existing pipeline system for installation without additional pipeline modification, improving the convenience of installation and maintenance. The feedback unit is configured to drive the station turntable 2 to rotate 180° in an directional manner based on the monitoring results.

[0021] The feedback unit includes a microcontroller 6, a flow sensor 62 fixedly mounted on the sewage inlet pipe 47 and the clean water outlet pipe 11, a rotary motor 61 fixedly mounted on the top of the dispensing cylinder 41, the output shaft end of the rotary motor 61 being fixedly connected to the station rotating frame 2, an encoder integrated inside the rotary motor 61, and the data terminals of the encoder and the two flow sensors 62 being connected to the microcontroller 6.

[0022] During equipment operation, the flow sensor 62 on the sewage inlet pipe 47 collects the inlet flow data in real time, and the flow sensor 62 on the clean water outlet pipe 11 collects the outlet flow data in real time, and transmits the two sets of flow data to the microcontroller 6 in real time. The microcontroller 6 calculates the difference between the inlet and outlet water flow rates and the pumping efficiency attenuation value in real time. When the flow rate difference exceeds the preset threshold or the pumping efficiency is lower than the set lower limit, it simultaneously determines that the degree of blockage of the filter element 38 and the degree of sludge accumulation in the pump casing 3 have reached the maintenance limit. The microcontroller 6 then sends a drive command to the rotary motor 61. The rotary motor 61 drives the station frame 2 to rotate 180°, switching the pump casing 3, which was originally in the pumping station, to the sludge cleaning station. Simultaneously, the sludge cleaning and regeneration of the filter element 38 and the self-cleaning of the pump casing 3 are completed. At the same time, the clean pump casing 3, which was originally in the sludge cleaning station, is switched to the pumping station to continue the sewage pumping and filtration. The encoder built into the rotary motor 61 collects the rotation angle data in real time and feeds it back to the microcontroller 6 to form a closed-loop control, ensuring the accuracy of the rotation angle of the station frame 2 and ensuring the sealing and accuracy of the flow channel connection. The above control logic achieves online synchronous identification of the blockage status of filter element 38 and the sludge accumulation status of pump casing 3 through real-time monitoring of flow sensor 62 and intelligent judgment of microcontroller 6. It eliminates the need for manual disassembly and inspection or timed shutdown for maintenance, and solves the problems of traditional water pump maintenance methods that cannot accurately match the actual clogging status of flow components, over-maintenance, or untimely maintenance. Meanwhile, through the closed-loop angle control of the encoder, the precise 180° switching of the dual pump housing and three stations is realized, ensuring the accuracy of the flow channel docking during the station switching process and avoiding problems such as flow channel misalignment, cross-contamination, and leakage caused by angle deviation. The station switching process can be completed in milliseconds, and the sewage pumping operation can be completed without interruption, realizing the uninterrupted continuous operation of the equipment. Furthermore, the feedback unit is highly integrated with the main structure of the equipment. The core control logic can be completed with only two sets of flow sensors 62. The control system has a simple structure, strong anti-interference ability, and can be adapted to long-term stable operation in complex working conditions such as sewage and sludge. At the same time, the flow difference threshold can be flexibly adjusted according to different water quality and different working conditions.

[0023] The pumping unit also includes a top shaft 311, a bottom shaft 312 and an outer shaft 313 rotatably connected to the pump casing 3. A synchronous belt is driven between the top shaft 311 and the bottom shaft 312, and the hollow shaft 32 is driven by the synchronous belt. Synchronous pulleys connected to the synchronous belt are installed on the top shaft 311, bottom shaft 312 and hollow shaft 32; Both the outer shaft 313 and the top shaft 311 are equipped with first bevel gears, and the two first bevel gears mesh orthogonally. A horizontal rotating wheel 314 is rotatably mounted inside the outer shaft 313, and a spindle 315 is rotatably connected inside the horizontal rotating wheel 314. A driven gear 316 connected to the power unit is mounted on the top of the outer shaft 313, the horizontal rotating wheel 314 and the spindle 315. Specifically, the outer shaft 313, the horizontal rotating wheel 314, and the spindle 315 are arranged coaxially and nested together. They rotate relative to each other through needle roller bearings and are axially limited by the shaft shoulder and the retaining ring, ensuring that the three can rotate independently without interference. The driven gears 316 on the top of the three are at different heights. A vertical rotating wheel 318 is rotatably mounted on the bottom shaft 312. Both the vertical rotating wheel 318 and the spindle 315 are equipped with second bevel gears, and the two second bevel gears mesh orthogonally. Along the circumferential direction, three cam portions 319 are arrayed on both the horizontal rotating wheel 314 and the vertical rotating wheel 318. Rollers 320 are rotatably connected to both the vertical vibration frame 34 and the horizontal vibration frame 33. The cam portion 319 on the horizontal rotating wheel 314 abuts against the roller 320 on the horizontal vibration frame 33, and the cam portion 319 on the vertical rotating wheel 318 abuts against the roller 320 on the vertical vibration frame 34. The contact stroke of the three cam portions 319 against the roller 320 is arranged in a gradient and is different from each other. Springs 321 are installed between the hollow shaft 32 and the pump shaft 35, and between the vertical vibrating frame 34 and the filter chamber 31. Third bevel gears are installed on the bottom shaft 312 and the hollow swirl cylinder 37, and the two third bevel gears mesh orthogonally.

[0024] In this embodiment, the three cam portions 319 on the horizontal rotating wheel 314 are evenly arranged in a 120° array along the circumference of the horizontal rotating wheel 314, and the contact strokes are 2.5mm, 4.0mm and 5.5mm respectively; The three cam portions 319 on the vertical rotating wheel 318 are evenly arranged in a 120° array along the circumference of the vertical rotating wheel 318, and their contact strokes are 3.0mm, 4.5mm, and 6.0mm respectively; The rotational phase difference between the horizontal rotor 314 and the vertical rotor 318 is set to 90° to avoid the simultaneous occurrence of the maximum amplitude in the horizontal and vertical directions, thereby controlling the overall vibration of the equipment while ensuring the intensity of dredging vibration. At the dredging station, the power unit drives the outer shaft 313, the horizontal rotating wheel 314 and the spindle 315 to rotate synchronously via the second gear 78; The outer shaft 313 drives the top shaft 311 to rotate through the meshing transmission of the first bevel gear. The top shaft 311 drives the bottom shaft 312 to rotate synchronously through the synchronous belt. Then, through the meshing transmission of the third bevel gear, it drives the hollow swirl cylinder 37 and the filter element 38 to rotate, thus completing the basic circumferential scraping action. The spindle 315 drives the vertical rotating wheel 318 to rotate synchronously through the meshing transmission of the second bevel gear. During the rotation, the three cams 319 with different contact strokes on the horizontal rotating wheel 314 abut against the rollers 320 on the horizontal vibrating frame 33 in sequence, pushing the horizontal vibrating frame 33 to drive the pump shaft 35 to slide back and forth along the axis of the pump casing 3 with gradient amplitude. The pump shaft 35 drives the impeller 36 to complete the axial reciprocating motion of the entire stroke. Through the gradient advancement of the three different strokes, the pump casing 3 achieves full coverage scraping from the water inlet end to the water outlet end, and from the inner circumference surface to the edge and corner fitting gap, removing the silt and sludge accumulated in the dead water area of ​​the pump casing 3, and achieving self-cleaning of the pump casing 3 without dead corners. The three cams 319 with different contact strokes arrayed on the vertical rotating wheel 318 abut against the rollers 320 on the vertical vibration frame 34 in sequence, pushing the vertical vibration frame 34 to drive the filter element 38 and brush cylinder 39 to perform up-and-down reciprocating vibrations with gradient amplitude along the axis of the filter element 38. Through the gradient vibration stroke, a differentiated shearing impact force is formed on the impurities at different depths of the filter element 38 and the entire surface of the filter element 38, breaking the hardened state of deep impurities in the filter pores. The 90° phase difference design between the horizontal rotor 314 and the vertical rotor 318 causes the maximum stroke of the axial reciprocating self-cleaning action of the impeller 36 and the axial vibration sludge removal action of the filter element 38 to be misaligned. Combined with the adaptive reset function of the spring 321, a smooth and shock-free periodic amplitude change action is formed, avoiding excessive equipment vibration caused by the superposition of the peak values ​​of the two actions. Through the design of three cam sections 319 with different contact strokes, the gradient amplitude control of the impeller 36 self-cleaning action and the gradient amplitude control of the filter element 38 sludge removal vibration are realized respectively, breaking through the limitations of traditional constant amplitude action that cannot cover the dead corner of the pump casing 3 and cannot adapt to the stripping requirements of sludge impurities of different particle sizes. The reciprocating stroke of the pump shaft 35 with gradient changes can accurately cover all the corners, gaps and dead water areas in the pump casing 3 where sludge is easy to accumulate, solving the problem that sludge accumulation in the pump casing 3 of traditional water pumps cannot be removed online. The gradient-varying filter element with 38 vibration strokes can generate a continuous alternating impact force on impurities accumulated at different depths within the filter pores, avoiding the resonance and caking of impurities caused by single-frequency vibration, thus improving the sludge removal effect. The hollow shaft 32 has a shaft hole that slides and connects with the pump shaft 35. The top of the filter element 38 has a synchronization groove. The cross-sections of the shaft hole, pump shaft 35, hollow vortex 37 and synchronization groove are all regular hexagonal. The outer periphery of the hollow vortex 37 is fixed with a first sealing ring that mates with the synchronization groove. The outer periphery of the brush cylinder 39 is fixed with a second sealing ring that mates with the water filter chamber cylinder 31. When the equipment is running, the pump shaft 35 with a regular hexagonal cross section slides freely along the axis of the pump casing 3 within the regular hexagonal shaft hole of the hollow shaft 32, while maintaining circumferential synchronous rotation with the hollow shaft 32. This ensures stable torque transmission between the pump shaft 35 and the hollow shaft 32 at the pumping station, driving the impeller 36 to rotate continuously and stably to achieve constant pressure pumping. At the sludge removal station, it ensures that while the pump shaft 35 rotates synchronously in the circumferential direction, it also smoothly completes the axial reciprocating sliding of the entire stroke, driving the impeller 36 to simultaneously achieve the dual actions of rotary pumping and reciprocating scraping self-cleaning, ensuring that there are no dead corners in the self-cleaning process of the pump casing 3. The hollow swirl cylinder 37 is inserted into the synchronous groove at the top of the filter element 38 through the hexagonal cross-section structure, driving the filter element 38 to rotate synchronously in the circumference. At the same time, when the vertical vibrating frame 34 drives the filter element 38 to reciprocate up and down in the direction of its own axis, the synchronous groove can slide freely along the axial direction of the hollow swirl cylinder 37, always maintaining circumferential synchronous transmission. The first sealing ring on the outer circumference of the hollow swirl cylinder 37 ensures the sealing fit at the joint between the two during the sliding process, without sewage leakage or crossflow problems. The second sealing ring on the outer periphery of the brush cylinder 39 is in full-seal fit with the inner wall of the filter chamber 31. During the process of the vertical vibration frame 34 driving the brush cylinder 39 to vibrate axially up and down, the second sealing ring always maintains the dynamic sealing state between the brush cylinder 39 and the filter chamber 31, preventing unfiltered sewage from entering the clean water side and ensuring the filtration accuracy of the equipment.

[0025] The pumping unit also includes a synchronous shaft 317 rotatably connected to the vertical vibrating frame 34. A synchronous bevel gear is installed on the synchronous shaft 317. A fourth bevel gear is installed on both the brush cylinder 39 and the filter element 38. Both fourth bevel gears are orthogonally meshed with the synchronous bevel gears. The two fourth bevel gears are symmetrically arranged about the horizontal plane where the axis of the synchronous shaft 317 is located.

[0026] During the rotation of the filter element 38, the fourth bevel gear on the filter element 38 drives the synchronous bevel gear on the synchronous shaft 317 to rotate. The synchronous bevel gear synchronously drives the fourth bevel gear on the brush cylinder 39 to rotate. The two fourth bevel gears, which are symmetrically arranged about the horizontal plane where the axis of the synchronous shaft 317 is located, make the filter element 38 and the brush cylinder 39 rotate in completely opposite directions, thereby achieving stable differential reverse rotation of the filter element 38 and the brush cylinder 39. The spiral brush blades 310 installed on the brush cylinder 39 form a relative scraping motion with the outer surface of the filter element 38 rotating in the opposite direction. In the pumping station, the directional reverse differential rotation achieves continuous scraping and cleaning of the surface of the filter element 38, preventing sludge from adhering and caking, and ensuring stable filtration efficiency. In the sludge cleaning station, the alternating reverse differential rotation, combined with the axial reciprocating vibration of the filter element 38, achieves a compound sludge cleaning action of circumferential forward and reverse rubbing and axial reciprocating rubbing on the surface of the filter element 38. At the same time, it is combined with the pulse-type high-pressure purified water backwashing of the backwash pipe 12 to remove the accumulated impurities on the surface of the filter element 38 and inside the filter holes.

[0027] The power unit includes a servo motor 7 fixedly mounted on the top surface of the outer valve ring 1. The output shaft end of the servo motor 7 is respectively fixedly mounted with a half-tooth gear ring 71 and a transmission gear ring 72. In this embodiment, the servo motor 7 has a rated power of 1.5kW and a rated speed of 1500r / min; A rotary guide shaft 73 is rotatably connected to the outer valve ring 1 at the pumping position, and a vibrating guide shaft 74 is rotatably connected to the dredging position. A torsion spring 75 is provided at the rotatable connection between the vibrating guide shaft 74 and the outer valve ring 1. A driven gear 76 is installed on both the rotary guide shaft 73 and the vibrating guide shaft 74. The driven gear 76 on the rotary guide shaft 73 meshes with the transmission gear ring 72, and the driven gear 76 on the vibrating guide shaft 74 meshes with the half-tooth gear ring 71. A first gear 77 is installed on the rotary guide shaft 73. The first gear 77 meshes with the driven gear 316 on the outer shaft 313 at the pumping position. Three second gears 78 are installed on the vibrating guide shaft 74. The three second gears 78 mesh with the driven gears 316 on the outer shaft 313, the vertical rotating wheel 318, and the spindle 315, respectively, at the dredging position. The microcontroller 6 is fixedly mounted on the outer periphery of the servo motor 7.

[0028] The pitch circle radius of the semi-tooth ring 71 is 1.5 to 3 times that of the pitch circle radius of the driven gear 76, preferably 2 times.

[0029] In this embodiment, the vertical water pump is suitable for extreme operating conditions with high hardness impurities, strong scaling, and high sand content. One rotation of the half-tooth ring 71 results in one transmission revolution for the driven gear 76. After the servo motor 7 starts, it synchronously drives the coaxial half-tooth ring 71 and transmission ring 72 to rotate continuously, realizing synchronous power output of dual stations. At the pumping station, the driven gear 76 on the rotary guide shaft 73 continuously meshes with the transmission gear ring 72, driving the rotary guide shaft 73 to rotate continuously in a directional manner. The first gear 77 on the rotary guide shaft 73 meshes with the driven gear 316 on the outer shaft 313 of the pump housing 3 at the pumping station, driving the pumping unit to rotate continuously in a directional manner, thus completing stable sewage pumping and filtration operations. At the dredging station, when the driven gear 76 on the vibrating guide shaft 74 meshes with the toothed section of the semi-toothed ring gear 71, the semi-toothed ring gear 71 drives the vibrating guide shaft 74 to rotate forward, compressing the rotary torsion spring 75. The three second gears 78 on the vibrating guide shaft 74 synchronously drive the outer shaft 313, the transverse rotating wheel 314, and the spindle 315 of the pump casing 3 at the dredging station to rotate forward. When the semi-toothed ring gear 71 rotates to the toothless section, the driven gear 76 disengages from the semi-toothed ring gear 71, and the rotary torsion spring 75 releases its elastic force to drive... The vibration guide shaft 74 rotates in the opposite direction to reset, which in turn drives the pumping unit of the sludge removal station to rotate in the opposite direction. The half-tooth ring 71 continues to rotate, which can realize the automatic alternating rotation of the pumping unit of the sludge removal station. With the precise tooth ratio and pitch circle radius ratio design of the half-tooth ring 71 and the passive gear 76, the four factors of the filter element 38 reversing frequency, axial vibration frequency, impeller 36 self-cleaning reciprocating frequency, and backwash pipe 12 pulse water flow frequency are precisely matched, so that the sludge removal, self-cleaning and backwashing actions are fully coordinated. The specific steps for using this invention are as follows: During the preparation phase, the flange interfaces of the equipment's sewage inlet pipe 47, clean water outlet pipe 11, and drain valve 46 are coaxially connected with the corresponding pipelines of the vertical water pump. After confirming that the pipelines are sealed without leakage, the inlet and outlet flow rate difference threshold and the rated operating parameters of the servo motor 7 are preset in the microcontroller 6. At the same time, the rotary motor 61 is controlled to drive the station frame 2 to reset to the initial station position, so that the two pump casings 3 are precisely aligned with the pumping station and the sludge removal station, respectively, completing the entire process preparation work before the equipment starts. During the working phase, after the equipment is started, the servo motor 7 synchronously drives the coaxial transmission gear ring 72 and half-tooth gear ring 71 to rotate continuously, providing synchronous power output for dual stations. In the pumping station, the transmission gear ring 72 stably meshes with the driven gear 316 on the outer shaft 313 of the corresponding pump housing 3 through the driven gear 76 and the first gear 77 on the rotating guide shaft 73, driving the pumping unit of the pump housing 3 to rotate continuously in a directional direction. The top shaft 311 drives the hollow shaft 32 and the pump shaft 35 to rotate synchronously in the circumference through the synchronous belt. The impeller 36 continuously introduces the sewage into the sewage inlet pipe 47, through the water inlet chamber 43 of the separator 41, the first valve hole 44, and the first branch pipe 49 into the water filter chamber 31. After being filtered by the filter element 38, it is pressurized and transported to the clean water discharge pipe 11, completing the core water conveying operation of the vertical water pump. During this process, the filter element 38 is driven to rotate directionally along its own axis by the hollow rotating cylinder 37. Simultaneously, it is driven by the synchronous shaft 317, synchronous bevel gear and symmetrically arranged fourth bevel gear on the vertical vibration frame 34 to drive the brush cylinder 39 and the filter element 38 to rotate in opposite directions with directional differential speed. This allows the spiral brush blades 310 to continuously adhere to and pre-scrape the outer surface of the filter element 38 to clean it, preventing sludge from adhering and hardening in advance. Simultaneously, at the dredging station, the semi-toothed ring 71 meshes with the driven gear 76 on the vibrating guide shaft 74, and with the reset action of the rotary torsion spring 75, the power is output alternately in opposite directions. The three second gears 78 on the vibrating guide shaft 74 mesh with the driven gears 316 of the outer shaft 313, the transverse rotating wheel 314, and the spindle 315 of the corresponding pump housing 3, respectively. On the one hand, this drives the hollow rotating cylinder 37 and the filter element 38 to achieve differential rotation in opposite directions, and simultaneously drives the brush cylinder 39 and the filter element 38 to form a differential rotation in opposite directions, so that the spiral brush blades 310 are aligned with the surface of the filter element 38. The system forms a bidirectional reciprocating rubbing and scraping motion, while the vertical rotating wheel 318 pushes the vertical vibrating frame 34 through three cams 319 with different contact strokes. This causes the filter element 38 and brush cylinder 39 to vibrate up and down periodically along the axis of the filter element 38. This causes the spiral brush blades 310 to form an axial reciprocating rubbing motion with the surface of the filter element 38 that matches the spiral angle. Combined with the pulsed high-pressure purified water supplied by the backwash pipe 12, the filter element 38 is flushed from the inside to the outside, removing the hardened sludge on the surface of the filter element 38 and the deep-seated impurities in the filter pores, thus completing the full-dimensional cleaning and regeneration of the filter element 38. On the other hand, the horizontal rotor 314 pushes the horizontal vibrating frame 33 through the cam part 319 with three different contact strokes, which drives the pump shaft 35 to slide back and forth along the axis of the pump casing 3 with gradient amplitude. Simultaneously, it drives the impeller 36 to complete the full stroke axial reciprocating motion in the pump casing 3, continuously scraping the sludge accumulated in the inner wall corners of the pump casing 3, the gap between the impeller 36 and the pump casing 3, and the dead water area of ​​the flow channel, so as to achieve self-cleaning without dead angles inside the pump casing 3. The sewage generated by sludge removal and self-cleaning enters the sewage discharge chamber 42 of the separator 41 through the second branch pipe 50 and the second valve hole 45, and is then discharged from the equipment through the sewage discharge valve 46. During equipment operation, the flow sensors 62 on the sewage inlet pipe 47 and the clean water outlet pipe 11 collect flow data in real time and transmit it to the microcontroller 6. When the difference between the inlet and outlet flow exceeds the preset threshold, the microcontroller 6 determines that the degree of blockage of the filter element 38 of the pump shell 3 and the degree of sludge accumulation of the pump shell 3 have reached the maintenance limit. Then, it controls the rotary motor 61 to drive the station frame 2 to rotate 180° in an directional direction. With the help of the encoder, it completes the closed-loop angle control and realizes the precise interchange of the two pump shells 3. The clean pump shell 3 that has been cleaned is switched to the pumping station to continue water delivery, and the pump shell 3 that was originally to be maintained is switched to the cleaning station to complete the cleaning and regeneration and self-cleaning of the pump shell 3. This cycle is repeated to achieve uninterrupted continuous operation of the equipment. In the final stage, when the water conveyance operation is completed and the machine needs to be shut down, first close the front valve of the sewage inlet pipe 47, and the equipment continues to run for 1-2 sludge cleaning cycles. After completing the full process of sludge cleaning and self-cleaning of the two pump casings 3, the microcontroller 6 controls the servo motor 7 and the rotary motor 61 to stop running, and then closes the clean water drain pipe 11 and the sewage drain valve 46 in sequence to complete the shutdown and finalization of the equipment.
