Description

Technical Field

[0001] This invention belongs to the field of pool pump technology, and specifically discloses a high-flow-rate pool pump. Background Technology

[0002] As the core power equipment of a pool water circulation and filtration system, the performance of the pool pump directly affects the water purification effect and the system's energy consumption. For large pools, commercial pools, or pools with spa functions, high flow rate pumps are typically required to meet the needs of long-distance water transport, overcoming pipeline resistance, and rapid circulation filtration. However, in actual operation, various impurities such as hair, sand, sebum, and flocculent matter inevitably mix into the pool water. These impurities enter the filter tank inside the pump body with the high-speed water flow, posing a serious challenge to the filtration system.

[0003] Currently, most commercially available pool pump filtration structures use filter baskets or cylindrical filter screens as interception elements. Under high flow conditions, the water velocity is extremely fast, and impurities are subjected to strong turbulent disturbances, often remaining suspended and unable to settle naturally. These suspended impurities not only easily pass through the filter screen (fine particles), but also quickly adhere to and accumulate on the filter screen surface, forming a dense blockage layer. As operating time increases, the effective filtration area of ​​the filter screen decreases sharply, leading to a significant increase in pump suction resistance, increased system pressure, and an actual output flow rate far lower than the rated flow rate. This not only causes increased motor energy consumption and pump overheating, but may even trigger overload protection and shut down, seriously affecting the normal circulation and filtration of the pool. Even more problematic is that because impurities remain suspended inside the filter tank for extended periods, they cannot actively settle to the bottom for collection. Cleaning requires manual shutdown, opening the tank lid, and removing the filter basket for rinsing or replacement, making the operation cumbersome and requiring extremely high maintenance frequency. Especially during peak pool usage seasons, the amount of impurities generated is large, often requiring daily cleaning, greatly increasing the operational and maintenance burden.

[0004] Therefore, there is an urgent need for a high-flow-rate swimming pool pump that can actively disrupt the suspended state of impurities, guide impurities to settle automatically, and achieve regular sewage discharge based on the amount of accumulation, so as to fundamentally solve the prominent problems of high filtration resistance, rapid flow decay, frequent maintenance, and poor sewage discharge effect in existing technologies. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the background art, and to propose a high-flow-rate swimming pool pump, including a base, a pump body, a vortex guide assembly, and a filter sensing assembly. The pump body is mounted on top of the base. A closed impeller and a guide vane are sequentially fixedly sleeved on the outside of the pump body's drive shaft from back to front. The closed impeller is used to convert rotational kinetic energy into pressure energy to maintain high flow output. The guide vane is used to pre-pressurize the water flow, reduce inlet vortices, and improve cavitation performance. A filter canister is connected to the front end of the pump body, and an inlet is connected to one end of the filter canister. The pump body is located above the interior. The filter is equipped with a water outlet and a filter cartridge for removing impurities. The vortex guide component is located above the inside of the filter cartridge and guides the water flow into the filter cartridge in a vortex manner, causing impurities to sink along the inner wall of the filter cartridge. The filter cartridge is connected to a ring frame by sinking tension members on both sides of the inner wall. The ring frame is fitted with a filter cloth, and a flexible tube extends from the bottom of the filter cloth. A solenoid valve is installed inside the flexible tube. A sludge storage box is provided at the bottom of the filter cartridge. An inlet expansion pipe is installed inside the filter cartridge near the water inlet and is clamped to the outside of the water inlet.

[0006] In the above technical solution, the vortex guide component further includes an arc-shaped guide ring, and two sets of arc-shaped guide rings are provided, with the two sets of arc-shaped guide rings being staggered vertically. One set of arc-shaped guide rings is located at the lower end of the drain outlet of the water inlet expansion pipe. An arc-shaped hook groove is machined on the inner surface of the arc-shaped guide ring, and an arc-shaped baffle is fixedly installed on the outer side of the arc-shaped guide ring near the arc-shaped hook groove.

[0007] In the above technical solution, the filter sensing component further includes two sets of gravity sensors, which are respectively installed on both sides of the bottom wall inside the impurity removal filter cartridge.

[0008] In the above technical solution, the sinking tensioning member further includes a shell, and the inner wall of the shell is provided with sliding grooves on both sides. A slider is slidably installed in both sets of sliding grooves. A sliding column is provided at the rear end of the slider, and an elastic element is provided at the end of the sliding column away from the slider.

[0009] In the above technical solution, the elastic element further includes a tension spring, one end of which is fixedly connected to the outer wall of the slide column, a slide cylinder is slidably installed at the end of the slide column away from the slider, the end of the slide cylinder is fixedly installed on the outer wall of the impurity removal filter cylinder, the end of the tension spring away from the slide column is fixedly connected to the outer wall of the slide cylinder, and an installation rod is connected to the lower end of the slider, the installation rod is T-shaped, and the lower end of the installation rod is installed inside the ring frame.

[0010] In the above technical solution, a telescopic tube is further provided on the lower part of the hose, and the lower end of the telescopic tube is connected to the inside of the sludge storage box.

[0011] In the above technical solution, a pressure sensor is further installed inside one end of the sludge storage box, and a sealing cap is threadedly connected to the bottom of the sludge storage box.

[0012] In the above technical solution, a screw cap is threadedly connected to the upper part of the filter barrel, and a backflushing pipe is fixedly inserted inside the screw cap, with the lower end of the backflushing pipe extending into the interior of the impurity removal filter barrel.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a vortex guiding component, including an arc-shaped guide ring, an arc-shaped hook groove and an arc-shaped baffle arranged in an alternating manner, to guide the water flow into the impurity removal filter cylinder in a vortex manner, so that the impurities rotate and sink along the inner wall of the impurity removal filter cylinder, avoiding the impurities from directly impacting the surface of the filter cloth, effectively delaying the clogging of the filter cloth, extending the filtration cycle, and reducing turbulence disturbance, while promoting the natural sedimentation of impurities.

[0014] 2. This invention utilizes a sinking tension member to connect the ring frame and the filter cloth, and works with a gravity sensor to detect the weight of impurities accumulated on the filter cloth in real time. When the accumulated impurities reach a set threshold, the filter cloth automatically sinks against the resistance of the tension spring and controls the solenoid valve to open, allowing the impurities to be discharged into the sludge storage box through the hose and telescopic tube, thus achieving automatic sludge discharge without the need for manual shutdown for cleaning, and significantly reducing the maintenance frequency.

[0015] 3. In this invention, a guide vane and a closed impeller are sequentially sleeved on the pump body drive shaft. The guide vane pre-pressurizes the inlet water, reduces inlet eddies, and improves cavitation performance. The closed impeller efficiently converts rotational kinetic energy into pressure energy. The synergistic effect of the two ensures that the filtration system has low resistance, low hydraulic loss, and stable and reliable output performance under high flow conditions.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-7 The high-flow-rate pool pump shown includes a base 1, a pump body 2, a vortex guide assembly, and a filter sensing assembly. The base 1 is made of high-strength metal material, providing excellent shock absorption and support performance to ensure stable operation of the pump body 2 under high-speed conditions. The pump body 2 is mounted on top of the base 1. A closed impeller 15 and a guide vane 16 are sequentially and fixedly fitted onto the outside of the pump body 2's drive shaft from back to front. The closed impeller 15 converts rotational kinetic energy into pressure energy to maintain high flow output. The guide vane 16 pre-pressurizes the water flow, reduces inlet vortices, and improves cavitation performance. A filter tank 5 is connected to the front end of the pump body 2, and an inlet 4 is connected to one end of the filter tank 5 for introducing pool circulating water. An outlet 3 is connected to the upper part of the pump body 2. Used to transport filtered clean water to a swimming pool or subsequent treatment equipment, the filter tank 5 is equipped with a filter cartridge 10 for removing impurities. A vortex guide component is set inside the filter cartridge 10 and above it to guide the water flow into the filter cartridge 10 in a vortex manner, so that impurities sink down along the inner wall of the filter cartridge 10. The filter cartridge 10 is connected to a ring frame 14 through sinking tension members set on both sides of the inner wall. A filter cloth 20 is embedded inside the ring frame 14. A hose extends from the bottom of the filter cloth 20. A solenoid valve 29 is installed inside the hose. A sludge storage box 7 is set at the bottom of the filter cartridge 10 to collect impurities that fall off the filter cloth 20. An inlet expansion pipe 11 is installed inside the filter cartridge 10 and near the inlet 4. The inlet expansion pipe 11 is clamped to the outside of the inlet 4. In this embodiment, the closed impeller 15 adopts a backward-curved blade structure, which can efficiently convert rotational kinetic energy into pressure energy, thereby maintaining high flow output. The guide vane 16 is located at the front end of the closed impeller 15 and is used to pre-pressurize the inlet water, effectively reducing inlet eddy currents, improving the cavitation performance of the pump body 2, and preventing bubbles from eroding the impeller surface under high flow conditions. The synergistic effect of the two allows the pump body 2 to maintain a stable, low-noise, and low-vibration operating state even under high flow conditions. The filter cloth 20 is made of multi-layer composite fiber material, which has high filtration accuracy and flow capacity, and is used to intercept fine impurities that have not settled in the water flow.

[0021] The vortex guide assembly includes an arc-shaped guide ring 12. Two sets of arc-shaped guide rings 12 are provided, and the two sets of arc-shaped guide rings 12 are staggered. One set of arc-shaped guide rings 12 is located at the lower end of the drain outlet of the water inlet expansion pipe 11. An arc-shaped hook groove 26 is machined on the inner surface of the arc-shaped guide ring 12. An arc-shaped baffle 28 is fixedly installed on the side of the arc-shaped guide ring 12 near the arc-shaped hook groove 26. In this embodiment, two sets of arc-shaped guide rings 12 are staggered vertically, with one set located above and the other below, and they are offset at a certain angle in the circumferential direction to create a swirling flow guiding effect. In actual operation, the water flow discharged from the inlet expansion pipe 11 first impacts the arc-shaped baffles 28 of the first set of arc-shaped guide rings 12, forcing the water flow to turn and flow out along the tangential direction of the arc-shaped hook grooves 26, forming an initial rotational motion. Subsequently, the water flow continues to flow downwards and encounters the second set of staggered arc-shaped guide rings 12, where it is again guided by the arc-shaped baffles 28 and constrained by the arc-shaped hook grooves 26, further enhancing the swirling flow intensity. After two stages of guidance, the water flow forms a stable and strong vortex flow field inside the impurity removal filter cylinder 10. Impurities in the water are thrown towards the cylinder wall under the action of centrifugal force and spiral down along the cylinder wall, while the central area of ​​the water flow is relatively clear, eventually flowing downwards towards the filter cloth 20.

[0022] The filter sensing assembly includes two sets of gravity sensors 18, which are respectively installed on both sides of the bottom wall inside the impurity removal filter cartridge 10. In this embodiment, the gravity sensor 18 is a high-precision resistance strain gauge or piezoelectric sensor, and its output signal is proportional to the applied pressure. The signal cable of the gravity sensor 18 is electrically connected to an external controller (such as a PLC or microcontroller system), which is based on existing technology and will not be described in detail here.

[0023] The sinking tensioning component includes a housing 13. Slide grooves 21 are provided on both sides of the inner wall of the housing 13. A slider 22 is slidably installed inside both sets of slide grooves 21. A slide column 27 is provided at the rear end of the slider 22. An elastic element, including a tension spring 25, is provided at one end of the slide column 27 away from the slider 22. One end of the tension spring 25 is fixedly connected to the outer wall of the slide column 27. A slide cylinder 24 is slidably installed at the end of the slide column 27 away from the slider 22. The end of the slide cylinder 24 is fixedly installed on the outer wall of the impurity removal filter cylinder 10. The end of the tension spring 25 away from the slide column 27 is fixedly connected to the outer wall of the slide cylinder 24. An installation rod 23 is connected to the lower end of the slider 22. The installation rod 23 is T-shaped, and its lower end is installed inside the ring frame 14. In this embodiment, when the weight of impurities accumulated on the filter cloth 20 increases, the ring frame 14 is subjected to a downward pulling force. This pulling force is transmitted to the slider 22 through the mounting rod 23, forcing the slider 22 to overcome the elastic force of the elastic element and slide to one side along the slide groove 21. The sliding of the slider 22 causes the sliding column 27 to extend outward, and the tension spring 25 is stretched. After the sewage discharge is completed, the weight of the impurities is reduced, the tension spring 25 returns to its original position, and pulls the sliding column 27, slider 22, mounting rod 23 and ring frame 14 to slide back to the initial position, thereby driving the ring frame 14 and filter cloth 20 back to the initial position. This sinking and stretching component has a compact structure, smooth sliding, and high reliability. It can automatically adapt to changes in the amount of impurities accumulated on the filter cloth 20, realizing the adaptive sinking and resetting of the filter cloth 20.

[0024] A telescopic tube 17 is slidably sleeved on the lower part of the hose, and the lower end of the telescopic tube 17 is connected to the inside of the sludge storage box 7. In this embodiment, the telescopic tube 17 is a multi-section corrugated tube structure with a certain telescopic length. The lower end of the telescopic tube 17 is connected to the interior of the sludge storage box 7, and the connection is sealed with a sealing ring or sealant to prevent water leakage. The outer diameter of the flexible tube is slightly smaller than the inner diameter of the telescopic tube 17, allowing the flexible tube to slide up and down inside the telescopic tube 17. At the same time, the gap between the two is small, making it difficult for impurities to leak out. In actual operation, when the filter cloth 20 sinks due to the accumulation of impurities, the flexible tube moves downward accordingly, and the telescopic tube 17 is squeezed to a deeper part and comes into contact with the gravity sensor 18, receiving a signal that sludge needs to be discharged. When the filter cloth 20 is reset, the hose moves upward. Since the lower end of the telescopic tube 17 is fixedly connected to the inside of the sludge collection box 7, while the hose can slide relative to it, the lower end of the hose remains connected to the sludge collection box 7 via the telescopic tube 17 regardless of the height of the filter cloth 20. This ensures that impurities can fall smoothly into the sludge collection box 7 without interrupting the drainage channel due to the raising or lowering of the filter cloth 20. Simultaneously, the telescopic tube 17 also guides and protects the hose, preventing it from bending or folding and causing blockages. This structure ensures the continuity and reliability of the automatic drainage process.

[0025] A pressure sensor 6 is installed inside the sludge storage box 7, and a sealing cover 19 is threadedly connected to the bottom of the sludge storage box 7. In this embodiment, the probe of the pressure sensor 6 extends into the inside of the sludge storage box 7 to monitor the changes in air pressure or water pressure inside the sludge storage box 7 in real time. A sealing gasket is provided between the sealing cover 19 and the sludge storage box 7 to prevent water leakage. As the automatic sewage discharge process proceeds, impurities continuously fall into the sewage storage box 7, gradually reducing its effective volume and increasing its internal pressure. The pressure sensor 6 monitors this pressure value in real time and transmits the signal to an external controller. When the pressure reaches a preset upper threshold, it alerts the operator that the sewage storage box 7 can be cleaned. The operator simply unscrews the sealing cap 19, pours out the impurities or rinses it with water, and then tightens the cap 19; no other parts need to be disassembled. This design enables automatic monitoring and convenient cleaning of the sewage storage box 7, preventing backflow of impurities or sewage discharge failure due to overfilling.

[0026] A screw cap 8 is threadedly connected to the upper part of the filter barrel 5. A backwash pipe 9 is fixedly inserted inside the screw cap 8. The lower end of the backwash pipe 9 extends into the interior of the impurity removal filter barrel 10. In this embodiment, after automatic sewage discharge is completed, a small amount of residual impurities may still remain on the surface of the filter cloth 20, or the filtration performance of the filter cloth 20 may decrease after long-term operation. In this case, the operator can connect the external water inlet pipe to the backwash pipe 9 to introduce external high-pressure clean water. The high-pressure clean water sprays out from the lower end of the backwash pipe 9, directly impacting the surface of the filter cloth 20 and the arc-shaped guide ring 12, washing away the residual impurities. The washed-off impurities, under gravity, fall into the sludge collection box 7 through the hose and telescopic pipe 17, thereby completely restoring the filtration performance of the filter cloth 20.

[0027] Working principle: Pool water enters the inlet diffuser 11 inside the filter tank 5 through inlet 4. The inlet diffuser 11 amplifies and stabilizes the water flow before delivering it to the impurity removal filter cartridge 10. After the pump body 2's drive shaft starts, the front guide vanes 16 pre-pressurize the water flow, effectively reducing eddy currents at inlet 4 and improving the cavitation performance of the pump body 2, laying the foundation for subsequent water delivery. The closed impeller 15 at the rear of the drive shaft rotates synchronously, efficiently converting rotational kinetic energy into pressure energy. This overcomes pipe resistance and filter structure resistance, allowing the filtered water to be output at high speed through outlet 3, ensuring the pump body 2's stable high-flow-rate water delivery characteristics. The water then enters the impurity removal filter cartridge 10 through the inlet diffuser 11. At 0, the water first contacts the vortex guide component at the top inside. Two sets of staggered arc-shaped guide rings 12 guide the water flow. In conjunction with the arc-shaped hook grooves 26 on the inner surface of the arc-shaped guide rings 12 and the arc-shaped baffles 28 on the outer side, the water flow trajectory is changed, forcing the water flow to vortex and rotate downward along the inner wall of the impurity removal filter cylinder 10. Under the action of vortex, impurities such as hair, sand, and flocculents in the water flow are subjected to the combined action of centrifugal force and gravity, and sink along the cylinder wall, avoiding the direct impact of impurities on the surface of the filter cloth 20. At the same time, the suspension effect of turbulence on impurities is reduced, creating conditions for impurity sedimentation. The water flow completes the preliminary filtration during the rotation process and then converges at the filter cloth 20. The swirling water flows through the filter cloth 20 on the ring frame 14. The filter cloth 20 performs secondary interception and filtration of fine impurities that have not settled in the water flow. The filtered clean water enters the pump body 2 to participate in power output. The intercepted impurities gradually accumulate on the surface of the filter cloth 20. The impurities accumulated at the bottom of the filter cloth 20 sink together with the hose and slide inside the telescopic tube 17. Specifically, the gravity of the accumulated impurities overcomes the elastic tension of the sinking tension member, causing the ring frame 14 to move downward. During the movement of the ring frame 14, it drives the connected mounting rod 23 and slider 22 to converge towards the center along the sliding groove 21 inside the housing 13. The slider 22 pulls the sliding column 27 to slide inside the sliding cylinder 24 and stretches the tension spring 25, realizing the smooth sinking of the filter cloth 20. When the filter cloth 20 has a certain weight, the telescopic tube 17 also sinks together until the telescopic tube 17 contacts the gravity sensors 18 on both sides of the bottom wall inside the impurity removal filter cylinder 10. The gravity sensors 18 detect the filter cloth 20 and the accumulated impurities. The overall weight is measured and the weight signal is transmitted to the external control in real time. When the weight of the accumulated impurities on the surface of the filter cloth 20 reaches the set threshold of the gravity sensor 18, the solenoid valve 29 in the hose at the bottom of the filter cloth 20 automatically opens. Under the action of gravity, the impurities accumulated on the filter cloth 20 fall through the hose into the telescopic tube 17 that is slidably sleeved on its outside, and finally enter the sludge storage box 7 at the bottom of the impurity removal filter cartridge 10 for centralized collection, realizing the automatic discharge of impurities. The pressure sensor 6 inside the sludge storage box 7 monitors the pressure change inside the box in real time. When the amount of impurities accumulated in the sludge storage box 7 increases, the space inside the box shrinks, and the pressure rises to the set value, the pressure sensor 6 sends a signal to the external control device to remind the staff to clean the impurities in the sludge storage box 7 in time. The bottom of the sludge storage box 7 is equipped with a threaded sealing cover 19. The staff can directly unscrew the sealing cover 19 to clean the impurities. The operation is convenient and does not require stopping the machine to disassemble the entire filter structure. After the sewage discharge is completed, the solenoid valve 29 closes, and the elastic restoring force of the tension spring 25 pulls the slide column 27 and the slider 22 to slide upward along the original trajectory, causing the ring frame 14 and the filter cloth 20 to return to the initial filtration position. Finally, external high-pressure clean water can be introduced through the backwash pipe 9 on the screw cap 8 above the filter bucket 5. The high-pressure clean water is sprayed from the lower end of the backwash pipe 9 onto the surface of the filter cloth 20 to backwash the filter cloth 20, flushing the residual impurities into the sludge storage box 7 and completely restoring the filtration performance of the filter cloth 20. After the backwash is completed, the backwash pipe 9 is closed, and the pump body 2 resumes normal filtration and water supply, effectively extending the service life of the filter cloth 20 and reducing the frequency of manual cleaning.
