Description

Technical Field

[0001] The present invention relates to the technical field of anti-blocking axial flow pumps, and particularly to an anti-blocking fluorine material axial flow pump that is convenient for cleaning and maintenance. Background Art

[0002] Axial flow pumps are widely used in industries, agriculture, sewage treatment and other fields. Traditional axial flow pumps have the problem of inconvenient cleaning and maintenance. Their internal structure is complex, disassembling and assembling are time-consuming and laborious, and high technical requirements are imposed on maintenance personnel. At the same time, the anti-blocking ability is poor, and sundries in the transported fluid are likely to accumulate in the pump body, causing blockage of the impeller and pipeline, resulting in a decrease in flow rate, head and efficiency, and even damage to the pump body. Since fluorine materials have good corrosion resistance, it is necessary to develop an anti-blocking fluorine material axial flow pump that is convenient for cleaning and maintenance.

[0003] In the patent with the publication number of CN220452331U, an anti-blocking submersible axial flow pump at the water inlet is disclosed, which includes a submersible axial flow pump body and a water inlet cover. The bottom end of the submersible axial flow pump body is provided with a water inlet cover, a frame is installed on the outer wall of the water inlet cover, a ring-shaped filter cover is installed at the bottom end of the water inlet cover on one side of the frame, a rotating shaft is installed at the central position inside the submersible axial flow pump body, a transfer sleeve is installed at the bottom end of the rotating shaft, an impeller is sleeved on the surface of the transfer sleeve, a driving shaft is installed at the bottom end of the transfer sleeve, and the bottom end of the driving shaft extends outside the ring-shaped filter cover. This utility model not only realizes the convenient scraping and removal of the filtered dirt by the anti-blocking submersible axial flow pump at the water inlet, facilitates the cutting and crushing treatment of larger and harder dirt, but also effectively reduces the blockage of the water inlet, improving the excellent anti-blocking performance of the submersible axial flow pump.

[0004] The existing technology has the following defects: it cannot perform backwashing through self-adjustment. When the fluorine material axial flow pump is running, medium impurities are likely to accumulate in the impeller, flow channel and other places, resulting in blockage. After blockage, problems such as a large drop in flow rate, difficulty in reaching the rated value, low conveying efficiency, large fluctuation in outlet pressure, increase in motor load, rise in current, heat generation and abnormal noise, large vibration of the pump body and obvious noise will occur, seriously affecting the use and efficiency. Therefore, it is very necessary to clean the impurities in time. However, the existing cleaning methods usually require manual disassembly of the pump body or the assistance of external flushing equipment, which not only has low efficiency but also increases costs. Therefore, a structure that can perform backwashing through self-adjustment needs to be set up to timely remove the impurities accumulated in the impeller and flow channel, avoid blockage, keep the pump with stable flow rate and outlet pressure, and achieve the effects of improving the conveying efficiency and reducing costs.

[0005] It is impossible to clean the filter plate at the water inlet in time: During the operation of the fluorine material axial flow pump, the filter plate at the water inlet is in long-term contact with the medium, and impurities will continuously accumulate on it. As the filter plate gradually becomes blocked, the water permeability is greatly reduced, the water flow at the water inlet becomes smaller, resulting in a serious shortage of the water intake of the equipment. This makes it difficult for related equipment such as water pumps and cooling systems to operate normally at full load, and the working efficiency is significantly reduced. Moreover, the existing equipment lacks effective means to detect the blockage of the filter plate in time, resulting in the inability of personnel to carry out cleaning work in time. Therefore, a structure for cleaning the filter plate at the water inlet in time needs to be set up to ensure smooth water flow, stable water flow at the water inlet, sufficient water intake of the equipment, and enable the water pump, cooling system, etc. to operate normally at full load, achieving the effects of improving work efficiency and extending the service life of the equipment. Summary of the Invention

[0006] In view of the problems existing in the prior art, such as the inability to perform backwashing through self-adjustment and the inability to clean the filter plate at the water inlet in time, a clogging-proof fluorine material axial flow pump that is easy to clean and maintain is proposed.

[0007] The present application provides a clogging-proof fluorine material axial flow pump that is easy to clean and maintain, and its purpose is: through the provided flushing mechanism, impurities accumulated on the impeller and flow channel can be removed in time to avoid blockage, enabling the pump to maintain stable flow rate and outlet pressure, achieving the effects of improving transportation efficiency and reducing costs; through the provided filtering mechanism, smooth water flow can be ensured, stable water flow at the water inlet can be achieved, sufficient water intake of the equipment can be ensured, and the water pump, cooling system, etc. can operate normally at full load, achieving the effects of improving work efficiency and extending the service life of the equipment.

[0008] The technical solution of the present invention is: A clogging-proof fluorine material axial flow pump that is easy to clean and maintain, including a driving motor, a water delivery component and a water inlet bellmouth fixedly installed at the bottom of the driving motor in sequence, a filtering mechanism arranged inside the water inlet bellmouth, and a flushing mechanism arranged above the filtering mechanism. The water delivery component includes a sealing housing fixedly installed at the bottom of the driving motor, a driving shaft sleeved on the output shaft of the driving motor, an impeller fixedly installed on the outer wall of the driving shaft, and a plurality of guide vane plates fixedly installed inside the sealing housing and evenly distributed. The filtering mechanism includes a central rod fixedly connected to the bottom of the driving shaft. The flushing mechanism includes an adjusting component arranged on the outer wall of the central rod and a claw-shaped support frame fixedly connected to the inner wall of the sealing housing.

[0009] The adjusting assembly includes a threaded block fixedly connected to the outer wall of the central rod. An adjusting column is arranged on the outer wall of the threaded block. Internal threads and external threads are respectively formed on the inner and outer walls of the adjusting column. The upper and lower ends of the internal threads are annular grooves, and the middle section is a threaded groove. The annular grooves at the upper and lower ends of the internal threads are both slidably connected to the threaded block. The threaded groove in the middle section of the internal threads is threadedly connected to the threaded block. The external threads are threadedly connected to the inner wall of the claw-shaped support frame. A rotating ring is rotatably connected to the bottom of the adjusting column.

[0010] With the above scheme, through the arranged adjusting assembly, when the driving shaft rotates forward, the threaded block slides in the annular groove at the lower end of the internal threads of the adjusting column and does not drive the adjusting column to move downward. When it is necessary to wash the guide vane body, the driving shaft rotates to drive the central rod to rotate reversely, and the threaded block on the central rod rotates accordingly. Since the threaded groove in the middle section of the internal threads of the adjusting column is threadedly connected to the threaded block and the external threads are threadedly connected to the inner wall of the claw-shaped support frame, the rotation of the threaded block will cause the adjusting column to move downward, and the rotating ring rotatably connected to the bottom of the adjusting column will also move downward accordingly until the threaded block slides in the annular groove at the upper end of the internal threads of the adjusting column and the adjusting column stops moving downward.

[0011] Further, a water inlet is formed between the water inlet horn and the bottom of the sealing housing. A plurality of guide vanes form a guide vane body inside the sealing housing. The impeller is located between the water inlet and the guide vane body.

[0012] With the above scheme, through the arranged water conveyance assembly, when the driving motor is started, its output shaft drives the driving shaft to rotate forward, and the impeller on the driving shaft rotates accordingly. Water enters the pump body from the water inlet formed between the water inlet horn and the bottom of the sealing housing, and then obtains energy through the impeller. Under the action of the guide vane body formed by a plurality of guide vanes, the water is stably conveyed out to realize the normal water conveyance function.

[0013] Further, the flushing mechanism further includes a plurality of dirt cleaning cavities opened inside the sealing housing. An opening and closing assembly is arranged on one side of the dirt cleaning cavity close to the impeller. An activated carbon adsorption block and two flushing water pipes are fixedly installed inside the dirt cleaning cavity. The end of the flushing water pipe away from the dirt cleaning cavity is fixedly connected to a cleaning nozzle. The cleaning nozzle is arranged inside the guide vane body and is used for cleaning the surface of the guide vanes.

[0014] With the above scheme, through the arranged flushing mechanism, after water enters the dirt cleaning cavity, it is further purified by the activated carbon adsorption block and then conveyed to the cleaning nozzle through the flushing water pipe to clean the surface of the guide vanes, remove the impurities accumulated on the surface of the guide vanes, avoid blockage, ensure that the pump can maintain a stable flow rate and outlet pressure, and improve the conveying efficiency.

[0015] Furthermore, the opening and closing assembly includes a lifting groove formed inside the sealed housing. A sliding door is slidably connected to the inner wall of the lifting groove. Support blocks are fixedly connected to both sides of the sliding door, and a second telescopic spring is fixedly connected between the outer wall of the support block and the inner wall of the lifting groove.

[0016] Furthermore, a second connecting rope is fixedly connected to the bottom of the sliding door. The end of the second connecting rope away from the sliding door is fixedly connected to the outer wall of the rotating ring, and the second connecting rope slides inside the claw-shaped support frame.

[0017] With the above solution, through the provided opening and closing assembly, the rotating ring is connected to the sliding door through the second connecting rope. When the rotating ring moves, it pulls the second connecting rope, causing the sliding door to slide in the lifting groove and stretching the second telescopic spring, thereby opening the sliding door and allowing the water inside the sealed housing to enter the dirt cleaning chamber under the rotation of the impeller.

[0018] Furthermore, the filtering mechanism includes a fixed block fixedly connected to the bottom of the central rod. A filter plate is installed between the outer wall of the fixed block and the inner wall of the water inlet horn, and a clamping assembly is arranged at the bottom of the filter plate.

[0019] Furthermore, the clamping assembly includes a rotating handwheel rotatably connected to the outer wall of the water inlet horn, and a plurality of sliding grooves formed in the inner wall of the water inlet horn. Clamping blocks are slidably connected to the inner walls of the plurality of sliding grooves. A first telescopic spring is fixedly connected between the end of the clamping block close to the rotating handwheel and the inner wall of the sliding groove, and a first connecting rope is fixedly connected between the clamping block and the inner wall of the rotating handwheel.

[0020] Furthermore, a dirt cleaning rod is threadedly connected to the bottom of the fixed block, and a plurality of brush heads are fixedly connected to the side of the dirt cleaning rod close to the filter plate.

[0021] With the above solution, through the provided filtering mechanism, the water passes through the filter plate of the filtering mechanism, and impurities in the water can be filtered out. The filter plate is installed between the fixed block and the inner wall of the water inlet horn and is fixed by the clamping assembly. When it is necessary to clean or replace the filter plate, rotate the rotating handwheel, and the first connecting rope pulls the clamping block to overcome the elastic force of the first telescopic spring, causing the clamping block to slide in the sliding groove, thereby releasing the clamping of the filter plate and facilitating the removal of the filter plate for cleaning or replacement. At the same time, the brush heads on the dirt cleaning rod threadedly connected to the bottom of the fixed block can clean the surface of the filter plate to a certain extent when the drive shaft drives the central rod to rotate, preventing excessive accumulation of impurities.

[0022] The beneficial effects of the present invention: Through the provided adjustment component, when the drive shaft rotates forward, the threaded block slides in the annular groove at the lower end of the internal thread of the adjustment column and does not drive the adjustment column to move downward. When it is necessary to flush the guide vane body, the drive shaft rotates to drive the central rod to rotate in the reverse direction, and the threaded block on the central rod rotates accordingly. Since the threaded groove in the middle section of the internal thread of the adjustment column is threadedly connected to the threaded block and the external thread is threadedly connected to the inner wall of the claw-shaped support frame, the rotation of the threaded block will cause the adjustment column to move downward. The rotating ring rotatably connected to the bottom of the adjustment column will also move downward accordingly until the threaded block slides in the annular groove at the upper end of the internal thread of the adjustment column and the adjustment column stops moving downward. Thus, the reverse flushing mode is entered through adjustment to timely remove the impurities accumulated in the impeller and the flow channel, avoid blockage, keep the pump with stable flow rate and outlet pressure, and achieve the effects of improving the conveying efficiency and reducing costs.

[0023] Through the provided flushing mechanism, the rotating ring is connected to the sliding door through the second connecting rope. When the rotating ring moves, it pulls the second connecting rope, causing the sliding door to slide in the lifting groove and stretching the second telescopic spring, thereby opening the sliding door and enabling the water in the sealed housing to enter the cleaning cavity under the rotation of the impeller. After the water enters the cleaning cavity, it is further purified by the activated carbon adsorption block and then conveyed to the cleaning nozzle through the flushing water pipe to clean the surface of the guide vane plate, remove the impurities accumulated on the surface of the guide vane plate, avoid blockage, ensure that the pump can maintain stable flow rate and outlet pressure, and improve the conveying efficiency.

[0024] Through the provided filtering mechanism, the water passes through the filter plate of the filtering mechanism, and the impurities in the water can be filtered out. The filter plate is installed between the fixed block and the inner wall of the water inlet horn and is fixed by the clamping component. When it is necessary to clean or replace the filter plate, rotate the rotating handwheel, and the first connecting rope pulls the clamping block to overcome the elastic force of the first telescopic spring, causing the clamping block to slide in the chute, thereby releasing the clamping of the filter plate and facilitating the removal of the filter plate for cleaning or replacement. At the same time, the brush head on the cleaning rod threadedly connected to the bottom of the fixed block can clean the surface of the filter plate to a certain extent when the drive shaft drives the central rod to rotate, preventing excessive accumulation of impurities.

[0038] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0039] Refer to Figures 1 - 12, a clog - proof fluorine material axial flow pump that is convenient for cleaning and maintenance is provided, which includes a driving motor 1, a water delivery component 2 and a water inlet horn 3 fixedly installed in sequence at the bottom of the driving motor 1, a filtering mechanism 4 arranged inside the water inlet horn 3, and a flushing mechanism 5 arranged above the filtering mechanism 4. The water delivery component 2 includes a sealing housing 21 fixedly installed at the bottom of the driving motor 1, a driving shaft 23 sleeved on the output shaft of the driving motor 1, an impeller 24 fixedly installed on the outer wall of the driving shaft 23, and a plurality of guide vane plates 22 fixedly installed inside the sealing housing 21 and evenly distributed. The filtering mechanism 4 includes a central rod 41 fixedly connected to the bottom of the driving shaft 23. The flushing mechanism 5 includes an adjusting component 55 arranged on the outer wall of the central rod 41, and a claw - shaped support frame 56 fixedly connected to the inner wall of the sealing housing 21.

[0040] Referring to Figures 9 - 11 , the adjusting component 55 includes a threaded block 555 fixedly connected to the outer wall of the central rod 41. An adjusting column 551 is arranged on the outer wall of the threaded block 555. Internal threads 554 and external threads 552 are respectively opened on the inner and outer walls of the adjusting column 551. The upper and lower ends of the internal thread 554 are annular grooves, and the middle section is a threaded groove. The annular grooves at the upper and lower ends of the internal thread 554 are both slidably connected to the threaded block 555, and the threaded groove in the middle section of the internal thread 554 is threadedly connected to the threaded block 555. The external thread 552 is threadedly connected to the inner wall of the claw - shaped support frame 56. A rotating ring 553 is rotatably connected to the bottom of the adjusting column 551.

[0041] Specifically, the driving motor 1 serves as a power source to provide power for the operation of the entire pump. When the driving shaft 23 rotates forward, it drives the impeller 24 to rotate to obtain energy, thereby making the water flow. When the driving shaft 23 rotates reversely, it drives the impeller 24 to stir to remove impurities attached to the impeller 24. The internal and external walls of the adjusting column 551 are respectively provided with internal threads 554 and external threads 552. The unique design of the internal thread 554 makes the cooperation mode between the threaded block 555 and the adjusting column 551 different in different situations. When the driving shaft 23 rotates forward, the threaded block 555 slides in the annular groove at the lower end of the internal thread 554 of the adjusting column 551, and the position of the adjusting column 551 remains unchanged. When the driving shaft 23 rotates reversely, the threaded block 555 threadedly rotates in the threaded groove in the middle section of the internal thread 554 of the adjusting column 551, and the adjusting column 551 moves downward until the threaded block 555 slides in the annular groove at the upper end of the internal thread 554 of the adjusting column 551, and the adjusting column 551 stops moving downward.

[0042] Through the provided adjusting component 55, when the drive shaft 23 rotates forward, the threaded block 555 slides in the annular groove at the lower end of the internal thread 554 of the adjusting column 551 and does not drive the adjusting column 551 to move downward. When it is necessary to flush the guide vane body, the drive shaft 23 rotates to drive the central rod 41 to rotate in the reverse direction. The threaded block 555 on the central rod 41 rotates accordingly. Since the middle threaded groove of the internal thread 554 of the adjusting column 551 is threadedly connected to the threaded block 555 and the external thread 552 is threadedly connected to the inner wall of the claw-shaped support frame 56, the rotation of the threaded block 555 will cause the adjusting column 551 to move downward. The rotating ring 553 rotatably connected to the bottom of the adjusting column 551 will also move downward accordingly until the threaded block 555 slides in the annular groove at the upper end of the internal thread 554 of the adjusting column 551, and the adjusting column 551 stops moving downward.

[0043] Referring to Figure 3 , a water inlet is formed between the bottom of the water inlet bell 3 and the bottom of the sealing housing 21. A plurality of guide vanes 22 form a guide vane body inside the sealing housing 21. The impeller 24 is located between the water inlet and the guide vane body.

[0044] Through the provided water conveyance component 2, when the drive motor 1 is started, its output shaft drives the drive shaft 23 to rotate forward. The impeller 24 on the drive shaft 23 rotates accordingly. Water enters the pump body from the water inlet formed between the water inlet bell 3 and the bottom of the sealing housing 21, and then obtains energy through the impeller 24. Under the action of the guide vane body formed by a plurality of guide vanes 22, the water is stably conveyed out to achieve the normal water conveyance function.

[0045] Referring to Figures 8 - 12 , the flushing mechanism 5 further includes a plurality of dirt cleaning chambers 52 opened inside the sealing housing 21. An opening and closing component 51 is arranged on one side of the dirt cleaning chamber 52 close to the impeller 24. An activated carbon adsorption block 53 and two flushing water pipes 54 are fixedly installed inside the dirt cleaning chamber 52. The end of the flushing water pipe 54 away from the dirt cleaning chamber 52 is fixedly connected to a cleaning nozzle 57. The cleaning nozzle 57 is arranged inside the guide vane body and is used for cleaning the surface of the guide vane 22.

[0046] Through the provided flushing mechanism 5, after water enters the dirt cleaning chamber 52, it is further purified by the activated carbon adsorption block 53 and then conveyed to the cleaning nozzle 57 through the flushing water pipe 54 to clean the surface of the guide vane 22, removing the impurities accumulated on the surface of the guide vane 22, avoiding blockage, ensuring that the pump can maintain a stable flow rate and outlet pressure, and improving the conveying efficiency.

[0047] Referring to Figure 8, the opening and closing assembly 51 includes a lifting groove 514 formed inside the sealed housing 21. A sliding door 511 is slidably connected to the inner wall of the lifting groove 514. Support blocks 513 are fixedly connected to both sides of the sliding door 511. A second telescopic spring 512 is fixedly connected between the outer wall of the support block 513 and the inner wall of the lifting groove 514. A second connecting rope 515 is fixedly connected to the bottom of the sliding door 511. One end of the second connecting rope 515 away from the sliding door 511 is fixedly connected to the outer wall of the rotating ring 553. The second connecting rope 515 slides inside the claw-shaped support frame 56.

[0048] By providing the opening and closing assembly 51, the rotating ring 553 is connected to the sliding door 511 through the second connecting rope 515. When the rotating ring 553 moves, it pulls the second connecting rope 515, causing the sliding door 511 to slide in the lifting groove 514 and stretching the second telescopic spring 512, thereby opening the sliding door 511 and allowing the water inside the sealed housing 21 to enter the sewage cleaning chamber 52 under the rotation of the impeller 24.

[0049] Refer to Figures 5 - 6 , the filtering mechanism 4 includes a fixing block 42 fixedly connected to the bottom of the central rod 41. A filter plate 43 is installed between the outer wall of the fixing block 42 and the inner wall of the water inlet horn 3. A clamping assembly 45 is provided at the bottom of the filter plate 43. The clamping assembly 45 includes a rotating handwheel 451 rotatably connected to the outer wall of the water inlet horn 3, and a plurality of sliding grooves 454 formed in the inner wall of the water inlet horn 3. Clamping blocks 455 are slidably connected to the inner walls of the plurality of sliding grooves 454. A first telescopic spring 453 is fixedly connected between one end of the clamping block 455 close to the rotating handwheel 451 and the inner wall of the sliding groove 454. A first connecting rope 452 is fixedly connected between the clamping block 455 and the inner wall of the rotating handwheel 451. A sewage cleaning rod 44 is threadedly connected to the bottom of the fixing block 42. A plurality of brush heads 46 are fixedly connected to one side of the sewage cleaning rod 44 close to the filter plate 43.

[0050] By providing the filtering mechanism 4, the water passes through the filter plate 43 of the filtering mechanism 4, and impurities in the water can be filtered out. The filter plate 43 is installed between the fixing block 42 and the inner wall of the water inlet horn 3 and is fixed by the clamping assembly 45. When it is necessary to clean or replace the filter plate 43, rotate the rotating handwheel 451. The first connecting rope 452 pulls the clamping block 455 to overcome the elastic force of the first telescopic spring 453, causing the clamping block 455 to slide in the sliding groove 454, thereby releasing the clamping of the filter plate 43 and facilitating the removal of the filter plate 43 for cleaning or replacement. At the same time, the brush heads 46 on the sewage cleaning rod 44 threadedly connected to the bottom of the fixing block 42 can clean the surface of the filter plate 43 to a certain extent when the drive shaft 23 drives the central rod 41 to rotate, preventing excessive accumulation of impurities.

[0051] During use, the fluoroplastic axial flow pump is installed in the sump through the wellbore. The driving motor 1 is started, and its output shaft drives the driving shaft 23 to rotate forward. The impeller 24 on the driving shaft 23 rotates accordingly. Water enters the pump body from the water inlet formed by the inlet bell 3 and the bottom of the sealing housing 21. The water passes through the filter plate 43 of the filtering mechanism 4 to filter out impurities in the water, and then obtains energy through the impeller 24. Under the action of the guide vane body formed by multiple guide vanes 22, the water is steadily conveyed out to achieve the normal water conveyance function. The filter plate 43 is installed between the fixed block 42 and the inner wall of the inlet bell 3 and can be fixed and replaced through the clamping assembly 45. At the same time, the brush head 46 on the cleaning rod 44 threadedly connected to the bottom of the fixed block 42 can clean the surface of the filter plate 43 to a certain extent when the driving shaft 23 drives the central rod 41 to rotate, preventing excessive accumulation of impurities. When it is necessary to wash the guide vane body, the driving shaft 23 rotates to drive the central rod 41 to rotate in the reverse direction and is adjusted through the adjusting assembly 55, so that the adjusting column 551 moves downward, and the rotating ring 553 is connected to the opening and closing assembly 51 through the second connecting rope 515, so that the water in the sealing housing 21 enters the cleaning chamber 52 under the rotation of the impeller 24. After the water enters the cleaning chamber 52, it is further purified by the activated carbon adsorption block 53 and then conveyed to the cleaning nozzle 57 through the flushing water pipe 54 to clean the surface of the guide vane 22, remove the impurities accumulated on the surface of the guide vane 22, avoid blockage, ensure that the pump can maintain a stable flow rate and outlet pressure, and improve the conveying efficiency.

[0052] The working principle of the present invention: The fluoroplastic axial flow pump is installed in the sump through the wellbore. The driving motor 1 is started, and its output shaft drives the driving shaft 23 to rotate forward. The impeller 24 on the driving shaft 23 rotates accordingly. Water enters the pump body from the water inlet formed by the inlet bell 3 and the bottom of the sealing housing 21. The water passes through the filter plate 43 of the filtering mechanism 4 to filter out impurities in the water, and then obtains energy through the impeller 24. Under the action of the guide vane body formed by multiple guide vanes 22, the water is steadily conveyed out to achieve the normal water conveyance function. At this time, the threaded block 555 slides in the annular groove at the lower end of the internal thread 554 of the adjusting column 551 and does not drive the adjusting column 551 to move downward.

[0053] The filter plate 43 is installed between the fixed block 42 and the inner wall of the inlet bell 3 and is fixed by the clamping assembly 45. When it is necessary to clean or replace the filter plate 43, the rotating handwheel 451 is rotated, and the first connecting rope 452 pulls the clamping block 455 to overcome the elastic force of the first telescopic spring 453, so that the clamping block 455 slides in the chute 454, thereby releasing the clamping of the filter plate 43 and facilitating the removal of the filter plate 43 for cleaning or replacement. At the same time, the brush head 46 on the cleaning rod 44 threadedly connected to the bottom of the fixed block 42 can clean the surface of the filter plate 43 to a certain extent when the driving shaft 23 drives the central rod 41 to rotate, preventing excessive accumulation of impurities.

[0054] When it is necessary to flush the guide vane body, the drive shaft 23 rotates to drive the central rod 41 to rotate in the reverse direction. The threaded block 555 on the central rod 41 rotates accordingly. Since the middle threaded groove of the internal thread 554 of the adjusting column 551 is threadedly connected to the threaded block 555, and the external thread 552 is threadedly connected to the inner wall of the claw-shaped support frame 56, the rotation of the threaded block 555 will cause the adjusting column 551 to move downward. The rotating ring 553 rotatably connected to the bottom of the adjusting column 551 will also move downward accordingly until the threaded block 555 slides in the upper annular groove of the internal thread 554 of the adjusting column 551, and the adjusting column 551 stops moving downward.

[0055] The rotating ring 553 is connected to the sliding door 511 through the second connecting rope 515. When the rotating ring 553 moves, it pulls the second connecting rope 515, causing the sliding door 511 to slide in the lifting groove 514 and stretching the second telescopic spring 512, thereby opening the sliding door 511 and allowing the water in the sealed housing 21 to enter the dirt cleaning chamber 52 under the rotation of the impeller 24.

[0056] After the water enters the dirt cleaning chamber 52, it is further purified by the activated carbon adsorption block 53 and then conveyed to the cleaning spray head 57 through the flushing water delivery pipe 54 to clean the surface of the guide vane plate 22, remove the impurities accumulated on the surface of the guide vane plate 22, avoid blockage, ensure that the pump can maintain a stable flow rate and outlet pressure, and improve the conveying efficiency.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
