Description

Technical Field

[0001] The present invention relates to the technical field of foundation pit pressurized water treatment, and in particular to a narrow and long foundation pit pumping and irrigation integrated equipment and a pumping and irrigation method thereof. Background Art

[0002] The foundation pit project mainly includes the design and construction of the foundation pit support system and earth excavation. The foundation pit support system is a temporary structure and is no longer needed after the underground engineering construction is completed. In a water-rich geological environment, excavation of deep foundation pits is very prone to pressurized water leakage. In order to avoid the accumulation of pressurized water, water collection wells and recharge wells will be set up. The water collection wells are used to collect and store the pressurized water, and then the pressurized water in the water collection wells is pumped into the recharge wells through water pumps.

[0003] The invention patent with authorization announcement number CN115094932B discloses an integrated device for pumping and injecting pressurized water into a deep foundation pit and a method for use, including an integrated pumping and injecting component, the water inlet end of the integrated pumping and injecting component is connected to a self-priming pump, and the drainage end of the integrated pumping and injecting component is connected to a recharge water pressure monitoring sensor. The integrated pumping and injecting component includes an outer shell, and a regulating pipe and a fixed pipe are provided inside the outer shell, and the regulating pipe and the fixed pipe are connected to each other; by arranging the regulating pipe and the fixed pipe, the regulating pipe and the fixed pipe form a regulating channel, and a reducing portion that can automatically adjust the inner diameter of the regulating pipe is provided on the regulating pipe, and the reducing portion automatically adjusts the inner diameter of the regulating pipe according to the pressure difference between the water collection well and the recharge well, so that the pressurized water can automatically adjust the water pressure and flow rate in the integrated device according to the water pressure of the recharge well, thereby achieving dynamic balance of pumping and injecting, improving pumping and injecting efficiency, and improving the service life of the back-end pipelines and equipment.

[0004] However, after actual application by technicians skilled in the art, it was found that the above device still has some shortcomings. The most obvious one is that although the filter screen in the filter tube can filter impurities in the pressurized water, when a large amount of impurities accumulate on the filter screen, the above device needs to go through more cumbersome operations to complete the removal of the filter screen. After the removed filter screen is cleaned, it is necessary to go through cumbersome operations again to complete the installation and fixation of the filter screen. The overall operation is too labor-intensive.

[0005] In addition, during the pumping process of pressurized water, impurities on the surface of the filter will continue to accumulate, and the continuously accumulated impurities will affect the normal passage of pressurized water and cause water pressure imbalance. In order to avoid the above situation, the filter often needs to be shut down and cleaned during the pumping process, which has a great impact on the pumping efficiency of pressurized water.

[0006] Therefore, it is necessary to invent a narrow and long foundation pit pumping and irrigation integrated equipment and a pumping and irrigation method thereof to solve the above problems. Summary of the Invention

[0007] The object of the present invention is to provide an integrated pumping and irrigation device for a narrow and long foundation pit and a pumping and irrigation method thereof, which is provided with a filtering mechanism, a driving mechanism, a cleaning mechanism and a debris removal mechanism, so that during the process of the filtering mechanism filtering the pressurized water, part of the filtered pressurized water enters the interior of the cleaning mechanism, and then the driving mechanism drives the filtering mechanism during the left movement, thereby causing the filter screen in the filtering mechanism to be transposed, and then the driving mechanism triggers the cleaning mechanism to complete the cleaning of the filter screen in the filtering mechanism, and during the subsequent rightward resetting process of the driving mechanism, the filter screen in the filtering mechanism is no longer transposed, so as to solve the problem that although the setting of the filter screen in the filter tube proposed in the above background technology is Although the impurities in the pressurized water can be filtered, when a large amount of impurities accumulate on the filter screen, the above-mentioned device needs to go through a relatively cumbersome operation to complete the disassembly of the filter screen, and after the disassembled filter screen is cleaned, it is necessary to go through cumbersome operations again to complete the installation and fixation of the filter screen. The overall operation is too manpower-consuming. In addition, during the pumping and filling process of the pressurized water, impurities on the surface of the filter screen will continue to accumulate, and the continuously accumulated impurities will affect the normal passage of the pressurized water and cause water pressure imbalance. In order to avoid the occurrence of the above situation, the filter screen often needs to be stopped for cleaning during the pumping and filling process, which has a great impact on the pumping efficiency of the pressurized water.

[0022] The present invention also discloses a pumping and irrigation method for a narrow and long foundation pit with integrated pumping and irrigation equipment, the method specifically comprising the following steps:

[0023] S1. Start the water pump located in the narrow foundation pit. The water pump inputs pressurized water into the water inlet pipe through a hose. The pressurized water then passes through the regulating pipe and the connecting pipe and is filtered by the adjacent filter. The filtered pressurized water enters the recharge well through the outlet pipe and the hose and is stored. During this process, some of the filtered pressurized water enters the water storage cylinder through the transmission pipe. The filtered impurities adhere to the left side of the upper filter and the inside of the upper installation tank.

[0024] S2. Start the drive motor. After the drive motor starts, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the outer sleeve to move left. When the outer sleeve moves left, it drives the inner sleeve to move left through the return spring, and at the same time drives the first magnetic plate to move left. When the inner sleeve moves left, it drives the first one-way screw to move left through the end plate. When the first one-way screw moves left, it drives the adjusting sleeve to rotate. When the adjusting sleeve rotates, it drives the transposition disk to rotate synchronously, thereby gradually transposing the two filter screens.

[0025] S3: When the outer sleeve moves to the left by a distance that reaches the first threshold, the left side of the end plate abuts against the right side of the adjacent sealing panel. At this point, the two filters are swapped. Simultaneously, due to the obstruction of the sealing panel, the first one-way screw, the end plate, and the inner sleeve cannot move further to the left. Subsequently, as the outer sleeve continues to move to the left, the return spring is continuously compressed, and the first magnetic plate continues to move to the left.

[0026] S4: When the outer sleeve moves to the left by a distance that reaches a second threshold, the first magnetic plate and the second magnetic plate are attached and attracted. Subsequently, as the outer sleeve continues to move to the left, the second magnetic plate drives the piston plate to move to the left synchronously through the guide plate. During the movement of the piston plate to the left, the output end of the transmission pipe is gradually blocked. Subsequently, the pressurized water after filtering inside the water storage cylinder is continuously pushed, so that the pressurized water passes through the valve on the partition plate and is finally pressurized through multiple spray holes and sprayed toward the adjacent filter screen to clean the filter screen. The cleaned pressurized water drives impurities to be discharged through the discharge pipe;

[0027] S5. During the cleaning process of the filter, the guide plate adjacent to the transmission pipe continuously blocks the output end of the transmission pipe. At the same time, the piston plate moves leftward, driving the second one-way screw to rotate continuously. The rotation of the second one-way screw drives the rotating disk to rotate continuously, thereby causing the pressurized water flow ejected from the spray hole to rotate synchronously, thereby completing the comprehensive cleaning of the filter;

[0028] S6. When the outer sleeve moves to the left by a distance reaching a third threshold, the filter screen is cleaned, and the adjustment sleeve moves to the leftmost end of the reciprocating thread on the outer side of the sealing frame. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves to the right and resets. During the rightward movement of the outer sleeve, the first magnetic plate is synchronously moved to the right, and when the first magnetic plate moves to the right, the adsorbed second magnetic plate is synchronously moved to the right;

[0029] S7: When the outer sleeve moves rightward by a distance reaching a fourth threshold, the piston plate and the guide plate are reset. At this time, the piston plate is located at the rightmost end inside the water storage cylinder. As the outer sleeve continues to move rightward, the first magnetic plate detaches from the right side of the second magnetic plate.

[0030] S8: When the outer sleeve moves rightwards by a distance reaching the fifth threshold, the compressed return spring is reset. Subsequently, as the outer sleeve continues to move rightwards, the outer sleeve drives the first one-way screw to move rightwards through the return spring, the inner sleeve, and the end plate. At this time, due to the limitation of the overrunning clutch, the transposition plate does not rotate;

[0031] S9, when the outer sleeve moves rightwards by a distance reaching the sixth threshold, the outer sleeve arrives at the initial position, that is, the rightmost end of the reciprocating thread outside the reciprocating screw, and the drive motor is stopped at this time.

[0032] Technical effects and advantages of the present invention:

[0033] The present invention is provided with a filtering mechanism, a driving mechanism, a cleaning mechanism and a debris discharge mechanism, so that during the process of the filtering mechanism filtering the pressurized water, part of the filtered pressurized water enters the cleaning mechanism, and then the filtering mechanism is driven during the left movement of the driving mechanism, thereby causing the filter screen in the filtering mechanism to be replaced, and then the driving mechanism triggers the cleaning mechanism to complete the cleaning of the filter screen in the filtering mechanism, and during the subsequent rightward resetting process of the driving mechanism, the filter screen in the filtering mechanism is no longer replaced. Compared with the same type of device in the prior art, the present invention does not need to disassemble the filter screen to complete the non-stop cleaning of the filter screen, has a higher degree of automation, saves manpower, does not require tedious operations, and will not affect the pressurized water pumping efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example 1

[0042] The present invention provides Figure 1-Figure 5 The illustrated embodiment of the invention is a narrow and long foundation pit pumping and irrigation integrated equipment, comprising a housing 1, a water inlet pipe 2 fixedly provided through the left side of the housing 1, and a water outlet pipe 3 fixedly provided through the right side of the housing 1, the input end of the water inlet pipe 2 being connected to a water pump via a hose, and the output end of the water outlet pipe 3 being connected to a recharging well via a hose, a pressure regulating mechanism 4 being provided on the left side of the interior of the housing 1, the water inlet pipe 2 being in communication with the pressure regulating mechanism 4, a filtering mechanism 5 being connected to the right side of the pressure regulating mechanism 4, a driving mechanism 6 being provided in the middle of the right side of the filtering mechanism 5, and a cleaning mechanism 7 and a debris removal mechanism 8 being provided at the bottom of both sides of the filtering mechanism 5, respectively;

[0043] During the leftward movement of the driving mechanism 6, the filtering mechanism 5 is driven, thereby causing the filter screen 54 in the filtering mechanism 5 to be replaced. Subsequently, the driving mechanism 6 triggers the cleaning mechanism 7, thereby completing the cleaning of the filter screen 54 in the filtering mechanism 5. During the subsequent rightward resetting process of the driving mechanism 6, the filter screen 54 in the filtering mechanism 5 is no longer replaced.

[0044] like Figure 3As shown, the pressure regulating mechanism 4 includes a regulating tube 41, a connecting tube 42, an regulating column 43 and a hydraulic cylinder 44, wherein the regulating tube 41 is fixedly sleeved on the right end of the water inlet pipe 2, the connecting tube 42 is fixedly penetrated and arranged in the middle of the right side of the regulating tube 41, two regulating columns 43 are provided, and are respectively slidably arranged at the inner front end and the inner rear end of the regulating tube 41, and the hydraulic cylinder 44 is fixedly arranged on the outside of the shell 1 and its output shaft slides through the shell 1 and is fixedly connected to the adjacent regulating column 43.

[0045] By setting up the above-mentioned structure, when the water pressure needs to be adjusted, the hydraulic cylinder 44 can drive its output shaft to extend or retract, and then the hydraulic cylinder 44 can drive the adjusting column 43 to slide inside the adjusting tube 41. It should also be noted that the pressure regulating mechanism 4 belongs to a solution that has been disclosed in the prior art and is not a necessary technical feature of this application. Therefore, this application does not elaborate on its more specific structure here.

[0046] like Figure 4 As shown, the filtering mechanism 5 includes a sealing frame 51, a transposition disc 52, an adjusting sleeve 53, a filter screen 54 and a sealing panel 55, wherein the sealing frame 51 is located inside the housing 1, the transposition disc 52 is rotatably arranged on the inner side of the sealing frame 51 through a bearing, the adjusting sleeve 53 is rotatably arranged on the inner side of the transposition disc 52 through an overrunning clutch, and two mounting grooves are sequentially provided on the side of the adjusting sleeve 53 from top to bottom. There are two filter screens 54, and the two filter screens 54 are respectively fixedly arranged at the right ends of the inner sides of the two mounting grooves. There are two sealing panels 55, and the two sealing panels 55 are respectively fixedly arranged on both sides of the sealing frame 51. The left sealing panel 55 is fixedly sleeved on the right end of the outer side of the connecting pipe 42, and the right sealing panel 55 is fixedly sleeved on the left end of the outer side of the water outlet pipe 3.

[0047] By setting the above structure, the outer sleeve 63 drives the first one-way screw 68 to move left through the return spring 64, the inner sleeve 65 and the end plate 67, so that when the adjusting sleeve 53 is driven to rotate, the adjusting sleeve 53 drives the transposition disk 52 to rotate synchronously, thereby gradually causing the two filter screens 54 to shift positions. When the outer sleeve 63 is subsequently moved right and reset, the outer sleeve 63 drives the first one-way screw 68 to move right through the return spring 64, the inner sleeve 65 and the end plate 67. At this time, due to the limitation of the overrunning clutch, the transposition disk 52 does not rotate.

[0048] like Figure 4As shown, the driving mechanism 6 includes a reciprocating screw 61, a driving motor 62, an outer sleeve 63, a return spring 64, an inner sleeve 65, a first magnetic plate 66, an end plate 67 and a first one-way screw 68, wherein the reciprocating screw 61 passes through the right side of the housing 1 and is rotatably connected to the housing 1 through a bearing, the driving motor 62 is fixedly arranged on the right side of the housing 1 and is transmission-connected to the reciprocating screw 61, and the outer sleeve 63, the return spring 64 and the inner sleeve 65 are sequentially sleeved on the outside of the reciprocating screw 61 from right to left. The outer sleeve 63 is transmission-connected to the reciprocating screw 61, the return spring 64 is fixedly connected between the outer sleeve 63 and the inner sleeve 65, the inner sleeve 65 is slidingly connected to the reciprocating screw 61 and is slidably nested in the inner side of the outer sleeve 63 along the horizontal direction, the first magnetic plate 66 is fixedly sleeved on the left end of the outer side of the outer sleeve 63, the end plate 67 is fixedly set on the left end of the inner sleeve 65, and the first one-way screw 68 is fixedly set in the middle of the left side of the end plate 67 and is threadedly connected to the inner side of the adjusting sleeve 53.

[0049] By setting up the above structure, the drive motor 62 drives the reciprocating screw 61 to rotate after it is started. When the reciprocating screw 61 rotates, it drives the outer sleeve 63 to move left. When the outer sleeve 63 moves left, it drives the inner sleeve 65 to move left through the return spring 64, and at the same time drives the first magnetic plate 66 to move left. When the inner sleeve 65 moves left, it drives the first one-way screw 68 to move left through the end plate 67. When the first one-way screw 68 moves left, it drives the adjusting sleeve 53 to rotate.

[0050] like Figure 5 As shown, the cleaning mechanism 7 includes a water storage cylinder 71, a transmission pipe 72, a second one-way screw 73, a piston plate 74, a guide plate 75, a second magnetic plate 76, a rotating disk 77, a spray hole 78 and a partition 79, wherein the water storage cylinder 71 is fixedly nested at the bottom right side of the adjacent sealing panel 55, the top end of the transmission pipe 72 is fixedly penetrated and arranged on the front side of the water outlet pipe 3, the bottom end of the transmission pipe 72 is fixedly penetrated and arranged on the front side of the water storage cylinder 71, the second one-way screw 73 is fixedly penetrated through the right end of the water storage cylinder 71 and extends to the inside of the water storage cylinder 71, the piston plate The transmission sleeve 74 is arranged on the outside of the second one-way screw 73, the guide plate 75 slides through the right side of the water storage cylinder 71 and is fixedly connected between the piston plate 74 and the second magnetic plate 76, the rotating disk 77 is fixedly arranged on the left end of the second one-way screw 73, and a plurality of spray holes 78 are provided. The plurality of spray holes 78 are evenly penetrated and arranged on the top of the right side of the rotating disk 77 in the vertical direction. The partition 79 is rotatably sleeved on the outside of the second one-way screw 73 through a bearing and is fixedly connected to the inner wall of the water storage cylinder 71. A plurality of valves are fixedly nested on the side of the partition 79.

[0051] By setting the above structure, after the first magnetic plate 66 and the second magnetic plate 76 are attached and adsorbed, as the outer sleeve 63 continues to move left, the second magnetic plate 76 drives the piston plate 74 to move left synchronously through the guide plate 75. During the process of the piston plate 74 moving left, the output end of the transmission pipe 72 is gradually blocked, and then the pressurized water after filtering inside the water storage cylinder 71 is continuously pushed, so that the pressurized water passes through the valve on the partition 79 and is finally pressurized and sprayed to the adjacent filter screen 54 through the multiple nozzle holes 78. During the cleaning process of the filter screen 54, the guide plate 75 adjacent to the transmission pipe 72 blocks the transmission pipe The output end 72 is continuously blocked, and at the same time, when the piston plate 74 moves to the left, it drives the second one-way screw 73 to rotate continuously. When the second one-way screw 73 rotates, it drives the rotating disk 77 to rotate continuously, thereby making the pressurized water flow ejected from the spray hole 78 rotate synchronously to complete the comprehensive cleaning of the filter 54. Subsequently, when the first magnetic plate 66 moves to the right and resets, it drives the adsorbed second magnetic plate 76 to move to the right synchronously. After the piston plate 74 and the guide plate 75 are reset, the piston plate 74 is located at the rightmost end inside the water storage cylinder 71. Subsequently, as the outer sleeve 63 continues to move to the right, the first magnetic plate 66 detaches from the right side of the second magnetic plate 76.

[0052] like Figure 4 As shown, the impurity discharge mechanism 8 includes a discharge pipe 81 and a stop valve 82 , wherein the discharge pipe 81 is fixedly nested at the left bottom of the adjacent sealing panel 55 , and the stop valve 82 is provided on the discharge pipe 81 .

[0053] By setting the above structure, the pressurized water is sprayed toward the adjacent filter screen 54 to clean the filter screen 54 , and the cleaned pressurized water drives the impurities to be discharged through the impurity discharge pipe 81 .

[0054] Example 2

[0055] The present invention also discloses a pumping and irrigation method for a narrow and long foundation pit with integrated pumping and irrigation equipment, the method specifically comprising the following steps:

[0056] S1. Start the water pump located in the narrow foundation pit. The water pump inputs pressurized water into the water inlet pipe 2 through the hose. The pressurized water then passes through the regulating pipe 41 and the connecting pipe 42 and is filtered by the adjacent filter 54. The filtered pressurized water enters the recharge well through the outlet pipe 3 and the hose and is stored. During this process, part of the filtered pressurized water enters the water storage cylinder 71 through the transmission pipe 72. The filtered impurities adhere to the left side of the upper filter 54 and the inside of the upper installation tank.

[0057] S2. Start the drive motor 62. After the drive motor 62 is started, it drives the reciprocating screw 61 to rotate. When the reciprocating screw 61 rotates, it drives the outer sleeve 63 to move left. When the outer sleeve 63 moves left, it drives the inner sleeve 65 to move left via the return spring 64, and at the same time drives the first magnetic plate 66 to move left. When the inner sleeve 65 moves left, it drives the first one-way screw 68 to move left via the end plate 67. When the first one-way screw 68 moves left, it drives the adjusting sleeve 53 to rotate. When the adjusting sleeve 53 rotates, it drives the transposition disk 52 to rotate synchronously, thereby gradually transposing the two filter screens 54.

[0058] S3: When the outer sleeve 63 moves to the left and reaches the first threshold, the left side of the end plate 67 is in contact with the right side of the adjacent sealing panel 55. At this time, the two filter screens 54 have completed the exchange. At the same time, due to the obstruction of the sealing panel 55, the first one-way screw 68, the end plate 67 and the inner sleeve 65 cannot move further to the left. Subsequently, as the outer sleeve 63 continues to move to the left, the return spring 64 is continuously compressed, and the first magnetic plate 66 continues to move to the left.

[0059] S4. When the outer sleeve 63 moves to the left by a distance that reaches the second threshold, the first magnetic plate 66 and the second magnetic plate 76 are attached and attracted. Subsequently, as the outer sleeve 63 continues to move to the left, the second magnetic plate 76 drives the piston plate 74 to move to the left synchronously through the guide plate 75. During the movement of the piston plate 74 to the left, the output end of the transmission pipe 72 is gradually blocked. Subsequently, the pressurized water after filtering inside the water storage cylinder 71 is continuously pushed, so that the pressurized water passes through the valve on the partition 79 and is finally pressurized through the multiple nozzle holes 78 and sprayed toward the adjacent filter screen 54 to clean the filter screen 54. The cleaned pressurized water drives impurities to be discharged through the discharge pipe 81.

[0060] S5. During the cleaning process of the filter 54, the guide plate 75 adjacent to the transmission pipe 72 continuously blocks the output end of the transmission pipe 72. At the same time, the piston plate 74 moves leftward, driving the second one-way screw 73 to rotate continuously. The rotation of the second one-way screw 73 drives the rotating disk 77 to rotate continuously, thereby causing the pressurized water flow sprayed from the spray hole 78 to rotate synchronously, thereby completing the comprehensive cleaning of the filter 54.

[0061] S6: When the distance the outer sleeve 63 moves to the left reaches the third threshold, the filter 54 is cleaned, and the adjustment sleeve 53 moves to the leftmost end of the reciprocating thread on the outer side of the sealing frame 51. Subsequently, as the reciprocating screw 61 continues to rotate, the outer sleeve 63 moves rightward and resets. During the rightward movement of the outer sleeve 63, the first magnetic plate 66 is synchronously moved rightward. When the first magnetic plate 66 moves rightward, the attracted second magnetic plate 76 is synchronously moved rightward.

[0062] S7: When the outer sleeve 63 moves rightward by a distance reaching a fourth threshold, the piston plate 74 and the guide plate 75 are reset. At this time, the piston plate 74 is located at the rightmost end of the water storage cylinder 71. As the outer sleeve 63 continues to move rightward, the first magnetic plate 66 is separated from the right side of the second magnetic plate 76.

[0063] S8: When the outer sleeve 63 moves rightward by a distance reaching the fifth threshold, the compressed return spring 64 is reset. Subsequently, as the outer sleeve 63 continues to move rightward, the outer sleeve 63 drives the first one-way screw 68 to move rightward through the return spring 64, the inner sleeve 65 and the end plate 67. At this time, due to the limitation of the overrunning clutch, the transposition plate 52 does not rotate.

[0064] S9. When the rightward movement distance of the outer sleeve 63 reaches the sixth threshold, the outer sleeve 63 arrives at the initial position, that is, the rightmost end of the reciprocating thread outside the reciprocating screw 61. At this time, the drive motor 62 is stopped.

4. A pumping and irrigation method for a narrow and long foundation pit according to any one of claims 1 to 3, characterized in that: The method specifically comprises the following steps: S1. Start the water pump located in the narrow foundation pit. The water pump inputs pressurized water into the water inlet pipe (2) through the hose. The pressurized water then passes through the regulating pipe (41) and the connecting pipe (42) and is filtered by the adjacent filter (54). The filtered pressurized water enters the recharge well through the outlet pipe (3) and the hose and is stored. During this process, part of the filtered pressurized water enters the water storage cylinder (71) through the transmission pipe (72). The filtered impurities adhere to the left side of the upper filter (54) and the inside of the upper installation groove; S2, start the driving motor (62), after the driving motor (62) is started, the reciprocating screw (61) is driven to rotate, and the reciprocating screw (61) drives the outer sleeve (63) to move leftward when the reciprocating screw (61) rotates. When the outer sleeve (63) moves leftward, the inner sleeve (65) is driven to move leftward through the return spring (64), and the first magnetic plate (66) is driven to move leftward at the same time. When the inner sleeve (65) moves leftward, the first one-way screw (68) is driven to move leftward through the end plate (67). When the first one-way screw (68) moves leftward, the adjusting sleeve (53) is driven to rotate. When the adjusting sleeve (53) rotates, the transposition disk (52) is driven to rotate synchronously, thereby gradually transposing the two filter screens (54); S3, when the outer sleeve (63) moves to the left and reaches the first threshold, the left side of the end plate (67) is in contact with the right side of the adjacent sealing panel (55), and the two filter screens (54) are now switched. At the same time, due to the obstruction of the sealing panel (55), the first one-way screw (68), the end plate (67) and the inner sleeve (65) cannot continue to move to the left. Subsequently, as the outer sleeve (63) continues to move to the left, the return spring (64) is continuously compressed, and the first magnetic plate (66) continues to move to the left. S4, when the outer sleeve (63) moves to the left and reaches the second threshold, the first magnetic plate (66) and the second magnetic plate (76) are attached and adsorbed. Subsequently, as the outer sleeve (63) continues to move to the left, the second magnetic plate (76) drives the piston plate (74) to move to the left synchronously through the guide plate (75). During the movement of the piston plate (74), the output end of the transmission pipe (72) is gradually blocked. Subsequently, the pressurized water after filtering inside the water storage cylinder (71) is continuously pushed, so that the pressurized water passes through the valve on the partition (79) and is finally pressurized through multiple spray holes (78) and sprayed to the adjacent filter screen (54) to clean the filter screen (54). The cleaned pressurized water drives impurities to be discharged through the impurity discharge pipe (81); S5. During the cleaning process of the filter screen (54), the guide plate (75) adjacent to the transmission pipe (72) continuously blocks the output end of the transmission pipe (72). At the same time, when the piston plate (74) moves to the left, it drives the second one-way screw (73) to rotate continuously. When the second one-way screw (73) rotates, it drives the rotating disk (77) to rotate continuously, thereby causing the pressurized water flow ejected from the spray hole (78) to rotate synchronously, thereby completing the comprehensive cleaning of the filter screen (54); S6, when the distance of the outer sleeve (63) moving to the left reaches the third threshold, the filter (54) is cleaned, and the adjustment sleeve (53) moves to the leftmost end of the reciprocating thread on the outside of the sealing frame (51), and then as the reciprocating screw (61) continues to rotate, the outer sleeve (63) moves right and resets. During the rightward movement of the outer sleeve (63), the first magnetic plate (66) is synchronously moved rightward, and when the first magnetic plate (66) moves rightward, the adsorbed second magnetic plate (76) is synchronously moved rightward; S7, when the outer sleeve (63) moves rightwards by a distance reaching a fourth threshold, the piston plate (74) and the guide plate (75) are reset, and the piston plate (74) is located at the rightmost end inside the water storage cylinder (71). Subsequently, as the outer sleeve (63) continues to move rightwards, the first magnetic plate (66) is separated from the right side of the second magnetic plate (76); S8, when the outer sleeve (63) moves rightwards by a distance reaching a fifth threshold, the compressed return spring (64) is reset, and subsequently as the outer sleeve (63) continues to move rightwards, the outer sleeve (63) drives the first one-way screw (68) to move rightwards through the return spring (64), the inner sleeve (65) and the end plate (67). At this time, due to the limitation of the overrunning clutch, the transposition plate (52) does not rotate; S9. When the rightward movement distance of the outer sleeve (63) reaches the sixth threshold value, the outer sleeve (63) arrives at the initial position, that is, the rightmost end of the outer reciprocating thread of the reciprocating screw (61), and the drive motor (62) is stopped at this time.
