Description

Technical Field

[0001] This invention relates to the field of agricultural engineering technology, specifically to a power device for a water pump used for irrigation. Background Technology

[0002] A water pump power unit for irrigation is a device that drives a pump impeller to pump water via a transmission shaft. Its core principle is that the water flow impacts the impeller blades to generate mechanical energy, which is then converted into the pump's water-lifting power. It is suitable for remote areas and features energy saving, environmental protection, and low maintenance costs.

[0003] Existing multistage centrifugal pumps mostly employ a fixed impeller structure and require periodic manual cleaning. This approach suffers from multiple technical drawbacks. The core operational process relies on manual inspection to assess impeller deposition and cavitation status, followed by manual disassembly or simple flushing equipment to remove contaminants. This manual-dependent maintenance process suffers from significant judgment lags and operational errors, making it difficult to accurately match the impeller cleaning effect with the actual deposition level. Furthermore, incomplete cleaning often leads to residual blockage in the flow channels, and damage to the anti-cavitation structure caused by the failure of silt adhesion, resulting in bubble collapse damage. In addition, the rigid structure of the traditional fixed impeller cannot adapt to the nonlinear flow field disturbances caused by fluctuations in water sediment content and water level changes. This results in wasted anti-cavitation margin under low sediment content conditions and rapid wear of the wear-resistant coating under high sediment content conditions, leading to a sharp drop in pump operating efficiency, stress concentration in flow components, and pressure pulsation in inlet and outlet pipelines. Moreover, emergency handling of existing solutions requires external maintenance equipment or shutdown and disassembly. This not only fails to utilize the pump's own flow channel characteristics for rapid sediment removal but also increases maintenance costs due to the excessively long fault handling cycle caused by external reliance.

[0004] Therefore, we propose a water pump power unit for irrigation in order to solve the problems mentioned above. Summary of the Invention

This differs from the traditional passive and inefficient solution that relies on manual disassembly and cleaning and replacement of the entire impeller, making the pump operation more reliable. First, by using an annular cleaning manifold and a targeted nozzle, combined with a micro high-pressure booster pump and a high-frequency electromagnetic pulse valve for reverse pulse jetting, the high-speed water jet can precisely break up the mud and sand clumps between the blade modules before startup, and during operation, it can also rely on the self-cleaning ribs on the impeller surface to form micro-vortices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water pump power device for irrigation, comprising a servo motor, a targeted reverse pulse cleaning component, and a modular quick-release component, wherein the targeted reverse pulse cleaning component has a modular quick-release component on one side of its outer wall;

The six electromagnetic pulse valves are used to achieve reverse pulse jet control, the six alloy strips are used to resist cavitation damage, and the twelve sets of turbulence-aiding strips are used to inhibit sediment deposition.

[0008] The modular quick-release assembly includes six mounting bases and six dovetail tenons. The top of each of the six mounting bases is provided with a concave dovetail groove, and the six concave dovetail grooves and six dovetail tenons work together to achieve quick assembly and disassembly.

[0009] Preferably, the bottom of the servo motor is rotatably connected to the pump shaft, the bottom of the pump shaft is rotatably connected to the central hub, the outer surface of the central hub is covered with a pump casing, and the outer surface of the pump casing is respectively provided with an inlet and an outlet.

[0010] Preferably, the targeted reverse pulse cleaning assembly further includes a connecting plate and six blades, with the top of the connecting plate connected to the bottom of the pump housing. A booster pump is fixedly installed on the top of the connecting plate, and the booster pump is used to provide the high-pressure water source required for cleaning. The water inlet of the booster pump is connected to an external water source.

[0011] Preferably, the outlet end of the booster pump is connected to an output pipe, and the water delivery end of the output pipe is connected to an inlet pipe.

[0012] Preferably, the bottom of the water inlet pipe is connected to an annular cleaning manifold, which is used to temporarily store high-pressure water. The bottom of the annular cleaning manifold is connected to six flanges, and the bottom of each of the six flanges is connected to a connecting pipe.

[0013] Preferably, the bottom of each of the six connecting pipes is connected to the top of a corresponding electromagnetic pulse valve.

[0014] Preferably, the outer surfaces of the six electromagnetic pulse valves are all connected to target nozzles, and the six target nozzles are all tapered converging nozzles. The tops of the six blades are all provided with grooves, and the tops of the six grooves are all provided with slots.

[0015] Preferably, each of the six slots is connected to a corresponding alloy strip, and a set of grooves is formed on one side of the outer wall of each of the six alloy strips. Both sides of the outer wall of each of the six blades are connected to a corresponding set of turbulence aids.

[0016] Preferably, the outer surfaces of the six mounting bases are connected to the outer surface of the central hub, and the interiors of the six mounting bases and the six dovetail tenons are provided with connecting holes, and the six dovetail tenons are integrally formed at one end of the corresponding blade.

[0017] Preferably, a pull plate passes through the inner surface wall of each of the connecting holes, and the pull plate is used to prevent the six blades from axially moving during high-speed rotation. Two fixing plates are fixedly connected to both ends of the pull plate, and a bolt passes through one side of the outer wall of the two fixing plates.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] In this invention, the synergistic effect of the targeted reverse pulse cleaning component and the modular quick-release component enables precise anti-deposition maintenance of the centrifugal pump. This differs from the passive and inefficient traditional solutions that rely on manual disassembly and cleaning or replacement of the entire impeller, making the pump operation more reliable. First, the annular cleaning manifold and targeted nozzle, combined with the reverse pulse jet of the micro high-pressure booster pump and high-frequency electromagnetic pulse valve, can precisely break up the mud and sand clumps between the blade modules before startup through high-speed water jet. During operation, the micro-vortex formed by the self-cleaning ribs on the impeller surface can dynamically prevent the adhesion of suspended mud and sand. At the same time, the dovetail groove connection structure of the quick-release component avoids the cleaning blind spots of the traditional integral impeller, allowing the jet of the cleaning component to reach the root of the blade and other areas prone to mud accumulation. The active removal of deposits by the cleaning component significantly reduces the wear of mud and sand on the impeller module and extends the replacement cycle of the quick-release component. The partial disassembly and assembly characteristics of the quick-release component allow for the individual replacement of damaged blades without disassembling the entire pump, solving the problem of resource waste caused by replacing the entire integral impeller when it is damaged.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1-3 As shown, this embodiment discloses a water pump power device for irrigation, including a servo motor 100, a targeted reverse pulse cleaning component 500, and a modular quick-release component 600. The modular quick-release component 600 is provided on one side of the outer wall of the targeted reverse pulse cleaning component 500.

[0033] like Figure 7 as well as Figure 9 As shown, the targeted reverse pulse cleaning assembly 500 includes six electromagnetic pulse valves 508, six targeted nozzles 509, six alloy strips 513, and six sets of turbulence-aiding strips 515. The six electromagnetic pulse valves 508 are used to achieve reverse pulse jet control, the six alloy strips 513 are used to resist cavitation damage, and the twelve sets of turbulence-aiding strips 515 are used to suppress sediment deposition.

[0034] like Figure 10As shown, the modular quick-release assembly 600 includes six mounting bases 601 and six dovetail tenons 602. The top of each of the six mounting bases 601 is provided with a concave dovetail groove, and the six concave dovetail grooves and the six dovetail tenons 602 cooperate to achieve quick assembly and disassembly.

[0035] This embodiment primarily addresses the issue that existing multistage centrifugal pumps often employ a fixed impeller structure and require periodic manual cleaning. This approach suffers from multiple technical drawbacks. Its core operational process relies on manual inspection to assess impeller deposits and cavitation status, followed by manual disassembly or simple flushing to remove contaminants. This manual maintenance process suffers from significant judgment lags and operational errors, making it difficult to accurately match the impeller cleaning effect with the actual degree of deposits. Furthermore, incomplete cleaning often leads to residual blockage in the flow channels, and damage to the anti-cavitation structure caused by the failure of silt adhesion, resulting in bubble collapse. Meanwhile, the rigid structure of the traditional fixed impeller cannot adapt to the nonlinear flow field disturbances caused by fluctuations in water sediment concentration and changes in water level. This leads to the waste of cavitation margin under low sediment concentration conditions and rapid wear of the wear-resistant coating under high sediment concentration conditions, resulting in a sharp drop in pump operating efficiency, stress concentration in flow components, and pressure pulsation in inlet and outlet pipelines. Furthermore, the emergency handling of existing solutions requires external maintenance equipment or shutdown and disassembly. This not only fails to utilize the pump's own flow channel characteristics to achieve rapid removal of sediment, but also increases maintenance costs due to the excessively long fault handling cycle caused by external dependence.

[0036] This embodiment addresses the problems of existing technologies by utilizing the synergistic effect of the targeted reverse pulse cleaning component 500 and the modular quick-release component 600 to achieve precise anti-deposition maintenance of the centrifugal pump. This differs from the traditional passive and inefficient approach that relies on manual disassembly and cleaning, and replacement of the entire impeller, making the pump operation more reliable. Firstly, the annular cleaning manifold 505 and the targeted nozzle 509, combined with the reverse pulse jet of the booster pump 502 and the electromagnetic pulse valve 508, precisely break up the sediment buildup between the blade 510 modules before startup using a high-speed water jet. Secondly, during operation, the turbulence-inducing strips 5 on the surface of the blade 510 further enhance the pump's performance. 15. Micro-vortices are formed to dynamically prevent the adhesion of suspended sediment. At the same time, the dovetail groove connection structure of the modular quick-release component 600 avoids the cleaning blind spots of traditional integral impellers, allowing the jet of the targeted reverse pulse cleaning component 500 to reach areas prone to sediment accumulation, such as the root of the blade 510. The active removal of sediment by the targeted reverse pulse cleaning component 500 significantly reduces the wear of sediment on the impeller module and extends the replacement cycle of the modular quick-release component 600. The partial disassembly and assembly characteristics of the modular quick-release component 600 allow for the individual replacement of damaged blades 510 without disassembling the entire pump, solving the problem of resource waste caused by replacing all damaged blades in traditional integral impellers.

[0037] according to Figures 1-3As shown, the bottom of the servo motor 100 is rotatably connected to the pump shaft 300, the bottom of the pump shaft 300 is rotatably connected to the central hub 400, the outer surface of the central hub 400 is covered with the pump casing 200, and the outer surface of the pump casing 200 is respectively provided with an inlet 700 and an outlet 800.

[0038] In this embodiment of the invention, the servo motor 100 first serves as the power source. When the servo motor 100 is powered on, it outputs torque and drives the pump shaft 300 to rotate. Then, the pump shaft 300 transmits the power to the central hub 400, which is the mounting carrier for the blades 510. The subsequent rotation of the blades 510 for pumping water depends on the rotational power of the servo motor 100. The pump casing 200 forms a closed flow channel space around the central hub 400 and the blades 510 to prevent water leakage. At the same time, it guides the water to enter smoothly from the inlet 700. After being pressurized by the rotation of the blades 510, the water is then transported to the irrigation pipe from the outlet 800.

[0039] according to Figure 4 As shown, the targeted reverse pulse cleaning assembly 500 also includes a connecting plate 501 and six blades 510. The top of the connecting plate 501 is connected to the bottom of the pump housing 200. A booster pump 502 is fixedly installed on the top of the connecting plate 501. The booster pump 502 is used to provide the high-pressure water source required for cleaning. The water inlet of the booster pump 502 is connected to an external water source.

[0040] In this embodiment of the invention, the connecting plate 501 is first fixed to the bottom of the pump housing 200, and the cleaning components such as the booster pump 502 and the annular cleaning manifold 505 are integrated into the pump body without the need for additional support. The booster pump 502 draws clean water from an external water source and effectively increases the water pressure through the internal plunger structure. At this time, the water pressurized by the booster pump 502 can crush the mud and sand on the blades 510 without damaging the coating of the blades 510 due to excessive pressure.

[0041] according to Figure 8 As shown, the outlet of the booster pump 502 is connected to an output pipe 503, and the water supply end of the output pipe 503 is connected to an inlet pipe 504.

[0042] In this embodiment of the invention, the high-pressure water pressurized by the booster pump 502 first enters the output pipe 503, and the output pipe 503 is made of 304 stainless steel, which can effectively withstand the water flow pressure. Then, it is connected to the inlet pipe 504 through a flange joint. The inner wall of the inlet pipe 504 is polished, which can effectively reduce the water flow resistance, thereby ensuring the stable pressure of the high-pressure water from the booster pump 502 to the inlet pipe 504.

[0043] according to Figures 7-8As shown, the bottom of the water inlet pipe 504 is connected to an annular cleaning manifold 505, which is used to temporarily store high-pressure water. The bottom of the annular cleaning manifold 505 is connected to six flanges 506, and the bottom of each of the six flanges 506 is connected to a connecting pipe 507.

[0044] In this embodiment of the invention, the high-pressure water delivered by the inlet pipe 504 first enters the annular cleaning manifold 505, which allows the high-pressure water to be evenly distributed within the pipe. The annular design of the annular cleaning manifold 505 allows the six blades 510 to obtain high-pressure water at the same pressure. Subsequently, the high-pressure water passes through six flanges 506, and each flange 506 corresponds to one blade 510, diverting the water to the connecting pipes 507. Due to the good sealing performance of the flanges 506, the water pressure in each connecting pipe 507 is kept stable. Then, each connecting pipe 507 supplies water to a separate electromagnetic pulse valve 508.

[0045] according to Figure 7 As shown, the bottom of each of the six connecting pipes 507 is connected to the top of a corresponding solenoid pulse valve 508.

[0046] In this embodiment of the invention, before the water pump starts and after it stops, the user can send an electrical signal to the electromagnetic pulse valve 508 through the control system. At this time, the electromagnet inside the valve quickly engages, opening the water flow channel and allowing the high-pressure water from the connecting pipe 507 to pass through. Simultaneously, the controller sets the pulse frequency, causing the electromagnetic pulse valve 508 to open and close rapidly, forming an effective pulse jet. This not only saves water but also enhances the mud and sand removal effect through pulse impact force. The independent control of the electromagnetic pulse valve 508 allows for more flexible cleaning operations.

[0047] according to Figures 6-7 As shown, the outer surfaces of the six electromagnetic pulse valves 508 are all connected to the target nozzles 509, and the six target nozzles 509 all adopt a conical constriction nozzle. The top of the six blades 510 is provided with a groove 511, and the top of the six grooves 511 is provided with a slot 512.

[0048] In this embodiment of the invention, after the high-pressure water delivered by the electromagnetic pulse valve 508 enters the conical nozzle, the water flow velocity will continuously increase due to the contraction of the diameter of the conical nozzle, forming a high-speed jet. The focusing effect of the conical nozzle can concentrate the high-pressure water to impact the mud and sand compaction area. The groove 511 on the blade 510 can accommodate the bottom of the alloy strip 513, and the slot 512 can hold the bottom of the alloy strip 513 to prevent the alloy strip 513 from shifting when the blade 510 rotates.

[0049] according to Figure 6 as well as Figure 9As shown, each of the six slots 512 is connected to a corresponding alloy strip 513. Each of the six alloy strips 513 has a set of grooves 514 on one side of its outer wall. Each of the six blades 510 has a set of turbulence aids 515 on both sides of its outer wall.

[0050] In this embodiment of the invention, firstly, during the operation of the water pump, the high-pressure microjet and high temperature generated by cavitation mainly impact the inlet edge of the blade 510. The alloy insert 513 can actively withstand and absorb this destructive energy, preventing irreversible damage to the blade 510 substrate through its own minimal wear. Secondly, the silt particles in the water flow cause severe cutting wear on the surface of the blade 510, especially the leading edge. The alloy insert 513, made of a wear-resistant alloy with a hardness far exceeding that of the blade 510 substrate material, can significantly slow down the wear rate and extend the life of the entire component. Furthermore, this slot 512 installation method allows for the replacement of only the damaged alloy insert 513 during subsequent use, thus effectively... This reduces maintenance costs. The grooves 514 on the alloy strips 513 guide the water flow smoothly and prevent the formation of vortices on the surface of the alloy strips 513, thus reducing water flow resistance. The turbulence-inducing strips 515 on both sides of the blades 510 are unevenly distributed, mainly concentrated in the middle and root of the blades 510, which are low-velocity areas where particle deposition is likely to occur. When the water flows over the surface of the blades 510 with alloy strips 513, micro-vortices are formed. These micro-vortices continuously scour the surface of the blades 510, destroying the adhesion and deposition conditions of silt particles, thereby keeping the flow channel smooth and unobstructed. This can fundamentally inhibit silt accumulation and reduce the need to replace the blades 510 due to cavitation and silt. Secondly, the drag-reducing effect of the grooves 514 ensures the operating efficiency of the water pump.

[0051] according to Figure 4 as well as Figure 10 As shown, the outer surfaces of the six mounting bases 601 are connected to the outer surface of the central hub 400. The six mounting bases 601 and the six dovetail tenons 602 are all provided with connecting holes, and the six dovetail tenons 602 are all integrally formed at one end of the corresponding blade 510.

[0052] In this embodiment of the invention, the mounting base 601 is first fixed to the central hub 400 by welding. Each mounting base 601 has a concave dovetail groove on its top, and the shape of the concave dovetail groove is perfectly matched with the shape of the dovetail tenon 602. When installing the blade 510, simply align the dovetail tenon 602 at one end of the blade 510 with the concave dovetail groove and push it in axially until the connection holes of the two are aligned. Unlike traditional impellers, multiple screws are not required. The dovetail connection significantly improves the disassembly and assembly efficiency compared to traditional screw connections. Moreover, the dovetail tenon 602 is integrally formed with the blade 510, which effectively improves the strength compared to traditional welded tenons. It will not break when the blade 510 rotates at high speed, thus ensuring the safe operation of the blade 510. Furthermore, each mounting base 601 corresponds to one blade 510, so other blades 510 do not need to be moved when replacing them, avoiding the waste of replacing all blades when the traditional integral impeller is damaged.

[0053] according to Figure 10 As shown, a pull plate 603 is inserted between the inner surfaces of each connecting hole, and the pull plate 603 is used to prevent the six blades 510 from moving axially when rotating at high speed. Two fixing plates 604 are fixedly connected to both ends of the pull plate 603, and a fastening bolt 605 is inserted through one side of the outer wall of the two fixing plates 604.

[0054] In this embodiment of the invention, after the blades 510 are first installed onto the mounting base 601 via the dovetail tenon 602, there will be slight axial movement space. At this time, the pull plate 603 is passed through the connection holes of the six mounting bases 601 and the dovetail tenon 602, and all the blades 510 are pulled laterally. Then, the fixing plate 604 is used to hold the two ends of the pull plate 603 and the bolts 605 are tightened. In this way, the axial force generated when the blades 510 rotate at high speed and the impact force generated by the water flow will be offset by the pull plate 603, avoiding axial movement. The presence of the pull plate 603 allows the blades 510 to effectively suppress axial movement and avoid friction between the blades 510 and the inner wall of the pump casing 200. The double fixation of the fixing plate 604 and the bolts 605 ensures that the pull plate 603 will not loosen. Even in the field vibration environment, the bolts 605 will not loosen. Moreover, the pull plate 603 is made of spring steel, which has a certain elasticity and can adapt to the slight thermal expansion and contraction of the blades 510, thereby ensuring long-term stable operation.

[0055] During operation, before the entire water pump starts working, the system receives a command and activates the targeted reverse pulse cleaning component 500. At this time, the booster pump 502 on the connecting plate 501 draws water from an external clean water source. The high-pressure water, after being pressurized by the booster pump 502, is then transported to the annular cleaning manifold 505 through the output pipe 503 and the inlet pipe 504. It is then distributed to the solenoid pulse valve 508 through the flange 506 and the connecting pipe 507. Subsequently, the solenoid pulse valve 508 opens and closes rapidly, causing the high-pressure water to form a high-speed jet through the conical targeted nozzle 509 to impact the silt and sand on the blades 510. After cleaning is completed, the system enters the operation phase. The servo motor 100 is powered on and starts, and the torque is transmitted to the central hub 400 through the pump shaft 300. This drives the six blades 510 to rotate at high speed. The water flows from the inlet 700 into the closed flow channel of the pump casing 200. After being pressurized by the blades 510, the water is transported to the irrigation pipe from the outlet 800. At the same time, the turbulence aids 515 on both sides of the blades 510 form micro-vortices. The water flows and prevents sediment from adhering. At this time, the alloy strip 513 in the slot 512 can withstand cavitation impact and effectively protect the blade 510 base. Then, the dovetail tenon 602 of the modular quick-release component 600 cooperates with the mounting base 601, and the pull plate 603, fixing plate 604 and bolt 605 lock the blade 510 to prevent axial movement of the blade 510 and ensure stable operation. When irrigation ends and the machine enters the shutdown stage, the servo motor 100 stops running and the targeted reverse pulse cleaning component 500 is restarted. If the blade 510 is damaged during long-term operation, the valve is closed to release water pressure, the bolt 605 is unscrewed and the pull plate 603 is removed, and the dovetail tenon 602 of the damaged blade 510 is pulled out from the dovetail groove of the mounting base 601. After replacing the new blade 510, the pull plate 603 is locked again. The whole process achieves precise protection and efficient maintenance throughout the entire life cycle through the synergy of the targeted reverse pulse cleaning component 500 and the modular quick-release component 600.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
