[0044] Furthermore, the lifting assembly includes an ear plate 7 fixed on the outer shell 6, a reciprocating screw rod 701 rotatably connected to the ear plate 7, a driving motor 702 fixed on the ear plate 7 and used to drive the reciprocating screw rod 701 to rotate, a first sleeve 703 threadedly connected to the reciprocating screw rod 701, and a connecting piece 8 for connecting the first sleeve 703 and the top of the filter seat 5.

[0045] Furthermore, the connecting member 8 includes a first elastic telescopic rod 801 fixedly connected to the first sleeve 703 and a pull rope 802 connected to the first elastic telescopic rod 801, and one end of the pull rope 802 away from the first elastic telescopic rod 801 passes through the outer shell 6 and is connected to the top of the filter seat 5, and a guide seat 803 connected to the pull rope 802 is provided on the outside of the filter tube 2.

[0046] Furthermore, the pushing assembly includes a support 9 fixed on the outer shell 6, a threaded rod 901 rotatably connected to the support 9, a second sleeve 902 threadedly connected to the threaded rod 901, a connecting plate 903 fixedly connected to the second sleeve 902, and a pushing plate 904 connected to one end of the connecting plate 903 away from the second sleeve 902, the connecting plate 903 is slidably connected to the outer shell 6, and the pushing plate 904 is slidably connected inside the outer shell 6.

[0047] Furthermore, a movable gear 9011 is fixedly provided on the threaded rod 901 , and a rack plate 7031 meshing with the movable gear 9011 is provided on the first sleeve 703 .

[0048] Furthermore, a concave hole 10 is formed on the housing 6 , and a second elastic telescopic rod 1001 is fixedly disposed in the concave hole 10 . One end of the second elastic telescopic rod 1001 away from the inner wall of the concave hole 10 is connected to the sealing plate 602 .

[0049] Furthermore, a push rod 9041 is fixedly provided on the pushing plate 904 , and the push rod 9041 and the sealing plate 602 are movably opposed to each other.

[0050] Specifically, when the upper filter screen 501 continues to filter the debris in the water body extracted from the water pumping pipe 3, too many debris are intercepted at the upper filter screen 501, and the output shaft of the driving motor 702 is controlled to drive the reciprocating screw rod 701 to rotate, and the first sleeve 703 outside the reciprocating screw rod 701 moves along the axial direction of the reciprocating screw rod 701, and the first sleeve 703 drives the filter seat 5 to slide in the movable groove 4 through the first elastic telescopic rod 801 and the pull rope 802, so that the filter seat 5 is When the lifting assembly drives the filter seat 5 to move to the impurity removal position, that is, the filter seat 5 moves to the inner wall of the housing 6 away from the filter tube 2, the filter seat 5 cannot move further. At this time, the lower filter screen 502 intercepts the impurities in the filter tube 2. As the first sleeve 703 continues to move, the first elastic telescopic rod 801 is compressed, and at this time, the rack plate 7031 outside the first sleeve 703 is meshed with the movable gear 9011, and the movable gear 9011 drives the threaded rod 901 to rotate, so that the threaded rod 90 The second sleeve 902 on the filter 1 moves axially along the threaded rod 901, and the second sleeve 902 drives the push plate 904 through the connecting plate 903 to push the debris intercepted by the filter screen 501 at the filter seat 5, until the push rod 9041 on the push plate 904 abuts against the sealing plate 602, so that the sealing plate 602 is forced to move away from the discharge port 601, and there is a distance between the push plate 904 and the sealing plate 602, so that the debris between the push plate 904 and the sealing plate 602 can fall automatically, thereby ensuring the impurity removal effect. As a result, as the first sleeve 703 moves to the end of the reciprocating screw rod 701, the first sleeve 703 starts to move back, so that the rack plate 7031 meshes with the movable gear 9011 in the opposite direction, the push plate 904 resets and moves, and the sealing plate 602 resets under the elastic force of the second elastic telescopic rod 1001. After the push plate 904 resets, the rack plate 7031 no longer meshes with the movable gear 9011 for transmission, so that the push plate 904 remains in its original position and does not move, and the drive motor 702 stops running;

[0051] After too much debris is intercepted at the lower filter screen 502, the drive motor 702 is continuously controlled to operate, and the output shaft of the drive motor 702 drives the reciprocating screw rod 701 to rotate, and the first sleeve 703 continues to move downward along the reciprocating screw rod 701, so that the first elastic telescopic rod 801 and the pull rope 802 no longer exert tension on the filter seat 5, and the filter seat 5 automatically moves downward under the action of its own gravity. When the filter seat 5 moves downward to the debris removal position, that is, the bottom of the filter seat 5 abuts against the inner wall of the lower shell 6 of the filter tube 2, the filter seat 5 cannot move downward any further, and as the first sleeve 703 continues to move, the first sleeve 703 and the lower shell 6 abut against each other. The movable gear 9011 of the pushing assembly at the shell 6 is engaged, so that the pushing assembly completes the pushing work of intercepting the debris at the lower filter 502. As the first sleeve 703 moves to the end of the reciprocating screw rod 701, the first sleeve 703 begins to move back, so that the rack plate 7031 and the movable gear 9011 are reversely engaged, and the pushing plate 904 is reset and moved. The sealing plate 602 is reset under the elastic force of the second elastic telescopic rod 1001. After the pushing plate 904 is reset, the rack plate 7031 is no longer engaged with the movable gear 9011 for transmission, so that the pushing plate 904 remains in its original position and does not move.

[0052] Example 3: Reference Figure 4 , Figure 5 , Figure 7 and Figure 8 , a drainage method for water conservancy project construction, as the preferred technical solution of the present invention, a movable plate 11 is slidably connected in the outer shell 6, and a plug rod 111 is fixedly provided on the movable plate 11 to be plugged into the filter holes of the upper filter 501 or the lower filter 502, an elastic element 112 is arranged between the movable plate 11 and the inner wall of the outer shell 6, a force block 12 is fixedly provided on the movable plate 11 to be slidably connected to the outer shell 6, an extrusion slope is provided on the force block 12, and a push plate 13 is fixedly provided on the first sleeve 703 to resist the force block 12 movably.

[0053] Specifically, after the lifting assembly drives the filter seat 5 to move to the impurity removal position, that is, when one end of the filter seat 5 moves to the inner wall of the side of the shell 6 away from the filter tube 2, as the lifting assembly continues to work, the first sleeve 703 drives the push plate 13 to abut against the force block 12, so that the force block 12 drives the movable plate 11 to move in the shell 6, so that the insertion rod 111 on the movable plate 11 is inserted into the filter holes of the upper filter screen 501 or the lower filter screen 502, avoiding the filter holes from being blocked, further improving the effect of removing impurities, and ensuring that the filter tube 2 continues to filter and remove impurities efficiently.

[0054] Example 4: Reference Figure 1 and Figure 2 , a drainage method for water conservancy project construction, as a preferred technical solution of the present invention, both ends of the filter tube 2 are provided with a first flange 14, and the water inlet end 101 of the delivery pump and the drainage end of the pumping pipe 3 are provided with a second flange 141 that matches the first flange 14.

[0055] Specifically, the filter pipe 2 is connected to the water pump 3 and the delivery pump by means of a flange, so as to improve the sealing effect of the connection between the pipelines.
