Description

Technical Field

[0001] The 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, excavating a deep foundation pit is very prone to pressurized water leakage. In order to avoid the accumulation of pressurized water, a collection well and a recharge well will be set up. The collection well is used to collect and store the pressurized water, and then the pressurized water in the collection well is pumped into the recharge well by a water pump.

[0003] The invention patent with authorization announcement number CN115094932B discloses an integrated device for pumping and injecting pressurized water in a deep foundation pit and a method for using the device, 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, the water discharge 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, an adjusting pipe and a fixed pipe are arranged inside the outer shell, and the adjusting pipe and the fixed pipe are interconnected; by arranging the adjusting pipe and the fixed pipe, the adjusting pipe and the fixed pipe form an adjusting channel, a reducing portion that can automatically adjust the inner diameter of the adjusting pipe is arranged on the adjusting pipe, the reducing portion automatically adjusts the inner diameter of the adjusting 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 the pumping and injecting efficiency, and improving the service life of the back-end pipelines and equipment.

[0004] However, after actual application by technicians in this field, it was found that the above-mentioned 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 are accumulated on the filter screen, the above-mentioned device needs to go through more complicated operations to complete the removal of the filter screen. After the removed filter screen is cleaned, it is necessary to go through complicated 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 the 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 the 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, wherein a filtering mechanism, a driving mechanism, a cleaning mechanism and a debris removal mechanism are provided, 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 filtering mechanism is driven during the leftward movement of the driving mechanism, so that the filter screen in the filtering mechanism is 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-mentioned background technology is Although impurities in pressurized water can be filtered, when a large amount of impurities are accumulated on the filter net, the above-mentioned device needs to go through relatively cumbersome operations to complete the disassembly of the filter net, and after the disassembled filter net is cleaned, it is necessary to go through cumbersome operations again to complete the installation and fixation of the filter net. The overall operation is too labor-intensive. In addition, during the pumping and filling process of pressurized water, impurities on the surface of the filter net 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 above situation, the filter net is often required to be shut down for cleaning during the pumping and filling process, which has a great impact on the pumping and filling efficiency of the pressurized water.

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

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

[0024] S2, start the driving motor. After the driving motor is started, 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 reset 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, so that the two filter screens are gradually transposed.

[0025] S3, when the outer sleeve moves to the left by a distance reaching the first threshold, the left side of the end plate fits with the right side of the adjacent sealing panel, and the two filters are now switched. At the same time, due to the obstruction of the sealing panel, the first one-way screw, the end plate and the inner sleeve cannot continue to move 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 reaching the second threshold, the first magnetic plate and the second magnetic plate are attached and adsorbed, and 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, and the piston plate gradually blocks the output end of the transmission pipe during the leftward movement, and then continuously pushes the pressurized water after filtering inside the water storage cylinder, so that the pressurized water passes through the valve on the partition and is finally pressurized through multiple spray holes and sprayed to the adjacent filter screen to clean the filter screen, and the cleaned pressurized water drives the impurities to be discharged through the impurity discharge pipe;

[0027] S5. During the cleaning process of the filter screen, 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 to the left to drive the second one-way screw to rotate continuously. When the second one-way screw rotates, it drives the rotating disk to rotate continuously, thereby causing the pressurized water flow sprayed from the spray hole to rotate synchronously to complete the comprehensive cleaning of the filter screen.

[0028] S6, when the distance of the outer sleeve moving to the left reaches the third threshold, the filter screen is cleaned, and the sleeve is adjusted to move 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 rightward and resets. During the movement of the outer sleeve to the right, the first magnetic plate is driven to move rightward synchronously. When the first magnetic plate moves to the right, the adsorbed second magnetic plate is driven to move rightward synchronously.

[0029] S7, when the outer sleeve moves rightwards by a distance reaching a fourth threshold, the piston plate and the guide plate are reset, and the piston plate is located at the rightmost end of the water storage cylinder. Subsequently, as the outer sleeve continues to move rightwards, the first magnetic plate is separated from the right side of the second magnetic plate;

[0030] S8, when the rightward movement distance of the outer sleeve reaches the fifth threshold, the compressed return spring is reset, and as the outer sleeve continues to move rightward, the outer sleeve drives the first one-way screw to move rightward 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 rightward movement distance of the outer sleeve reaches the sixth threshold value, the outer sleeve arrives at the initial position, that is, the rightmost end of the reciprocating thread on the outer side of 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 removal mechanism, so that in 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 leftward movement of the driving mechanism, so that the filter screen in the filtering mechanism is replaced, and then the driving mechanism triggers the cleaning mechanism to complete the cleaning of the filter screen in the filtering mechanism, and the filter screen in the filtering mechanism is no longer replaced during the subsequent rightward resetting process of the driving mechanism. 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 cumbersome operations, and will not affect the pumping efficiency of pressurized water.

[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 to complete 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 slidably arranged at the inner front end and the inner rear end of the regulating tube 41 respectively, and the hydraulic cylinder 44 is fixedly arranged on the outer side 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 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 the present application. Therefore, the present 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 disk 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 disk 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 disk 52 through an overrunning clutch, and two mounting grooves are sequentially provided on the side of the adjusting sleeve 53 from top to bottom, two filter screens 54 are provided, and the two filter screens 54 are respectively fixedly arranged at the right ends of the inner sides of the two mounting grooves, and two sealing panels 55 are provided, and the two sealing panels 55 are respectively fixedly arranged on both sides of the sealing frame 51, the left side sealing panel 55 is fixedly sleeved on the right end of the outer side of the connecting pipe 42, and the right side 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 reset 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 transpose. 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 reset 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 with 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 with 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 on the middle part 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 the above structure, the driving motor 62 can drive 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 right bottom of the adjacent sealing panel 55, the top end of the transmission pipe 72 is fixedly penetrated and arranged on the front of the water outlet pipe 3, the bottom end of the transmission pipe 72 is fixedly penetrated and arranged on the front 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 arranged, and a plurality of the 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, and 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 movement of the piston plate 74 to the left, the output end of the transmission pipe 72 is gradually blocked, and then the pressurized water filtered inside the water storage cylinder 71 is continuously pushed, so that the pressurized water passes through the valve on the partition plate 79 and is finally pressurized and sprayed to the adjacent filter screen 54 through the multiple spray 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 72. 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 sprayed from the spray hole 78 rotate synchronously to complete the comprehensive cleaning of the filter screen 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 is detached from the right side of the second magnetic plate 76.

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

[0053] By setting the above structure, after the pressurized water is sprayed toward the adjacent filter screen 54 to clean the filter screen 54 , 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 of a narrow and long foundation pit pumping and irrigation integrated equipment, the method specifically comprising the following steps:

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

[0057] S2, start the driving motor 62. After the driving 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 leftward. When the outer sleeve 63 moves leftward, it drives the inner sleeve 65 to move leftward through the return spring 64, and at the same time drives the first magnetic plate 66 to move leftward. When the inner sleeve 65 moves leftward, it drives the first one-way screw 68 to move leftward through the end plate 67. When the first one-way screw 68 moves leftward, it drives the adjusting sleeve 53 to rotate. When the adjusting sleeve 53 rotates, it drives the transposition disk 52 to rotate synchronously, so that the two filter screens 54 are gradually transposed.

[0058] S3, when the outer sleeve 63 moves to the left by a distance reaching 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 replaced. 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.

[0059] S4, when the outer sleeve 63 moves to the left by a distance reaching 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 to the left, the output end of the transmission pipe 72 is gradually blocked, and then the pressurized water filtered 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 spray holes 78 and sprayed to the adjacent filter screen 54, so as to clean the filter screen 54. The cleaned pressurized water drives the impurities to be discharged through the impurity discharge pipe 81;

[0060] 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, the piston plate 74 moves to the left to drive 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 sprayed from the spray hole 78 to rotate synchronously, so as to complete the comprehensive cleaning of the filter screen 54.

[0061] S6, when the distance of the outer sleeve 63 moving to the left reaches the third threshold, the filter screen 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, it drives the adsorbed second magnetic plate 76 to move rightward synchronously.

[0062] S7, when the outer sleeve 63 moves rightwards to 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 of the water storage cylinder 71. 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;

[0063] S8, when the rightward movement distance of the outer sleeve 63 reaches the fifth threshold, the compressed return spring 64 is reset, and 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, and the driving motor 62 is stopped at this time.

[0065] Example 3

[0066] It should also be noted that the first threshold, the second threshold and the third threshold increase in sequence, and the fourth threshold, the fifth threshold and the sixth threshold increase in sequence. At the same time, the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold and the sixth threshold are recorded for the convenience of accurately describing the actual working conditions of the scheme;

[0067] When the solution of the present application is actually produced, according to the actual specifications of the reciprocating screw 61, the first threshold value, the second threshold value, the third threshold value, the fourth threshold value, the fifth threshold value and the sixth threshold value are all specific values.

8. A pumping and irrigation method for a narrow and long foundation pit with integrated pumping and irrigation equipment, 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 screen (54). The filtered pressurized water enters the recharging well through the water 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 screen (54) and the inside of the upper installation groove. S2, starting the driving motor (62). After the driving 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 leftward. When the outer sleeve (63) moves leftward, it drives the inner sleeve (65) to move leftward through the return spring (64), and at the same time drives the first magnetic plate (66) to move leftward. When the inner sleeve (65) moves leftward, it drives the first one-way screw (68) to move leftward through the end plate (67). When the first one-way screw (68) moves leftward, 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). S3, when the distance of the outer sleeve (63) moving to the left reaches the first threshold, the left side of the end plate (67) fits with the right side of the adjacent sealing panel (55), and the two filter screens (54) are now replaced. 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 distance of the outer sleeve (63) moving to the left reaches the second threshold, the first magnetic plate (66) and the second magnetic plate (76) are attached and adsorbed, and 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), and the piston plate (74) gradually blocks the output end of the transmission pipe (72) during the movement to the left, and then continuously pushes the pressurized water after filtering inside the water storage cylinder (71), so that the pressurized water passes through the valve on the partition (79) and is finally pressurized through the plurality of spray holes (78) and sprayed toward the adjacent filter screen (54), so as to clean the filter screen (54), and the cleaned pressurized water drives the 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), and at the same time, the piston plate (74) moves to the left to drive 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 sprayed from the spray hole (78) to rotate synchronously, so as to complete the comprehensive cleaning of the filter screen (54); S6, when the distance of the leftward movement of the outer sleeve (63) reaches the third threshold value, the filter screen (54) is cleaned, and the adjustment sleeve (53) is moved to the leftmost end of the reciprocating thread on the outside 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 driven to move rightward synchronously. When the first magnetic plate (66) moves rightward, it drives the adsorbed second magnetic plate (76) to move rightward synchronously. S7, when the rightward movement distance of the outer sleeve (63) reaches a fourth threshold value, the piston plate (74) and the guide plate (75) are reset, and at this time the piston plate (74) is located at the rightmost end inside the water storage cylinder (71), and subsequently 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); S8, when the rightward movement distance of the outer sleeve (63) reaches the fifth threshold value, the compressed return spring (64) is reset, and 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), and 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 driving motor (62) is stopped at this time.
