Several sets of telescopic sleeves are slidably connected. The cleaning assembly also includes a filter screen 3 5, a fixing rod 4 51, a rotating rod 3 52, a scraper 1 53, and a scraper 2 54. The outer wall of the filter screen 3 5 is slidably connected to the inner wall of the integrated prefabricated pump station 1. One end of the fixing rod 4 51 is fixedly installed on the outer wall of the spring 2 412. The top of filter screen 3 5, the inner wall of fixed rod 4 51 and one end of rotating rod 3 52 are hinged by a worm spring.

One side of the outer wall of scraper 2 54 is fixedly installed on one side of the outer wall of scraper 1 53. The outer walls of scraper 1 53 and scraper 2 54 are both inclined. The outer walls of scraper 1 53 and scraper 2 54 are slidably connected to the inner wall of integrated prefabricated pump station 1 and the outer wall of filter screen 28. Scraper 1 53 and scraper 2 54 are used to clean the scale adhering to the inner wall of integrated prefabricated pump station 1 and the outer wall of filter screen 28.

[0041] In use, tap water is delivered to the integrated prefabricated pumping station 1 through the inlet pipe 23. The water level in the integrated prefabricated pumping station 1 is measured by the level sensor 21, thereby controlling the activation of several submersible pumps 24 to deliver water. The submersible pumps 24 deliver water through the water delivery pipe 25 to the collection pipe 26, and then through the collection pipe 26 to the outside of the integrated prefabricated pumping station 1. The water is then pressurized by the booster pump 27. The water pressure can be increased or decreased according to usage requirements. By opening the cover 2, one can climb up the ladder 22 to the integrated prefabricated pumping station 1. Inside the prefabricated pumping station 1, internal parts are installed or repaired. Water entering through the inlet pipe 23 is filtered through filter screen 28 to remove scale. By pulling the fixing rod 32 away from the crank handle 3, the fixing rod 31 provides support and limits its movement, causing it to disengage from the crank handle 3. Then, the crank handle 3 is turned, causing the rotating rod 33 to rotate, which in turn rotates the winding wheel 34, which in turn drives the pulley... The rope 35 moves, causing it to wind up onto the winding wheel 34. Positioning rod 36 limits the rope 35, causing it to move the positioning block 37 closer to the filter screen 5. Spring 45 provides elasticity to the locking block 44. The fixing block 46 provides support to the locking block 44 and spring 45 while simultaneously limiting the positioning block 37. The locking block 44 can also engage with the positioning block 37, limiting its position. Support rod 47 provides support to the fixing block 46, and fixing rod 42 provides support to the rotating rod 48. The rotating rod 48 provides support to the supporting rod 47, enabling the positioning block 37 to move the fixing rod 42. The fixing rod 42 then moves the filter screen 49, pushing the scale at the bottom of the integrated prefabricated pump station 1 to one side of the filter screen 5. The expansion sleeves 410 and 413 work together to limit the movement of the filter screen 49, ensuring it remains horizontal during movement. Simultaneously, the springs 411 and 412 work together to allow the filter screen 49 to return to its original position. Figure 2As shown, when filter screen 2 49 moves to the side of filter screen 3 5, the stop block 4 actuates sliding rod 1 41, and the fixing rod 3 42 limits sliding rod 1 41. Sliding rod 1 41 drives sliding rope 43 to move, and sliding rope 43 drives locking block 44 to retract into fixing block 46. Then, sliding rod 1 41 continues to move, causing support rod 1 47 to rotate around rotating rod 2 48, so that fixing block 46 moves out of positioning block 37. Continuing to rotate the handle 3 causes positioning block 37 to engage with fixing rod 4 51. This causes the filter screen 35 to move. During the upward movement of the filter screen 35, the scraper 153 scrapes off the scale adhering to the inner wall of the integrated prefabricated pump station 1 and the surface of the filter screen 28. During the movement of the scraper 153, when the scraper 153 contacts the outer wall of the filter screen 28 and the inner wall of the integrated prefabricated pump station 1 and bounces away, the scraper 153 will rotate around the rotating rod 352 as the axis, so that the scraper 254 contacts the outer wall of the filter screen 28 and the inner wall of the integrated prefabricated pump station 1 to perform scale removal.

[0042] Example 2

[0043] The technical solution that differs from that of Embodiment 1 in this embodiment includes: replacing the telescopic sleeve assembly with a hydraulic telescopic rod, and adding a limiting component for filter screen 3 5, so that filter screen 3 5 remains straight up and down during its up and down movement.

[0044] This invention also provides a method for water supply using a multi-stage pressurized integrated prefabricated pumping station, comprising the following steps:

[0045] S1. After closing the water inlet pipe 23 and completing the water transfer inside the integrated prefabricated pump station 1 by the submersible pump 24, release the fixation of the crank handle 3 and turn the crank handle 3.

[0046] S2. By turning the handle 3, the filter screen 2 49 moves closer to the filter screen 3 5, thereby cleaning the scale at the bottom of the integrated prefabricated pump station 1.

[0047] S3. When filter screen 2 49 moves to the stop block 4, the positioning block 37 is automatically unlocked. Continuing to turn the crank handle 3 will only move filter screen 3 5 towards the side closer to the crank handle 3.

[0048] S4. The scale is lifted up through the filter screen 35, and the scale adhering to the inner wall of the integrated prefabricated pump station 1 and the surface of the filter screen 28 along the path is cleaned.

[0049] The stop block 4 is compatible with the sliding rod 41, the support rod 47, the fixing block 46, and the positioning block 37. The number of submersible pumps 24 can be set as needed.

S2. By turning the handle (3), the filter screen two (49) moves closer to the filter screen three (5), thereby cleaning the scale at the bottom of the integrated prefabricated pump station (1); S3. When filter screen 2 (49) moves to the stop block (4), the positioning block (37) is automatically unlocked. Continue to turn the handle (3) to drive the positioning block (37) into the fixing rod 4 (51), thereby only driving filter screen 3 (5) to move towards the side closer to the handle (3). S4. The scale is lifted up through the filter screen three (5), and the scale adhering to the inner wall of the integrated prefabricated pump station (1) and the surface of the filter screen one (28) along the path is cleaned.

2. The multi-stage pressurized integrated prefabricated pumping station water supply system according to claim 1, characterized in that: The integrated prefabricated pumping station (1) is equipped with a conveying component for conveying drinking water.

3. The multi-stage pressurized integrated prefabricated pumping station water supply system according to claim 1, characterized in that: The stop block (4) is compatible with the sliding rod (41), the support rod (47), the fixed block (46), and the positioning block (37). The number of submersible pumps (24) can be set as needed.
