[0031] Based on the above disclosed structure, when the water conservancy project is executed to drain water:

[0032] First, the end of the water suction pipe 6 is completely inserted into the accumulated water in the water conservancy project foundation pit, then the pump body 2 is started and the rotating disc 13 is driven to rotate at the same time, the rotating disc 13 drives the fixed rod 14 to rotate around the axis of the rotating disc 13, so that the fixed rod 14 pushes the sliding groove on the sliding plate 12 and slides in the sliding groove, so that the sliding plate 12 drives the sliding frame 10 to reciprocate up and down in the filter box 4, thereby driving one end of the filter screen 17 to reciprocate through the connecting plate 11, and further driving the filter screen 17 to reciprocate up and down around the rotating axis on one side of the through groove 16, so as to realize the vibration of the filter screen 17;

[0033] The filter box 4 and the collection box 7 are in a closed state, the pump body 2 makes the air in the filter box 4 and the collection box 7 quickly exhaust through the connecting pipe 9 and the water outlet pipe 3, so that the air pressure in the filter box 4 is rapidly reduced, and then the water suction pipe 6 sucks the accumulated water into the filter box 4, the accumulated water in the foundation pit falls on the filter screen 17, the waste water passes through the filter screen 17 and falls on the guide slope at the bottom of the filter box 4, and then flows along the guide slope to the end of the connecting pipe 9, and then is discharged through the pump body 2 and the water outlet pipe 3, the silt and garbage in the accumulated water are isolated on the filter screen 17, and gradually roll off along the upper surface of the filter screen 17 in the vibration process of the filter screen 17, and finally roll off through the through groove 16 and fall into the collection box 7, so as to avoid the silt and garbage from being accumulated on the filter screen to cause blockage, and realize efficient drainage.

[0034] In addition, for the cleaning of silt and garbage, the following structure is preferably provided:

[0035] The collection box 7 is of L-shaped structure, a spiral conveying rod 15 is rotatably connected in one end of the collection box 7, and an inverted U-shaped structure of a pushing frame 19 is slidably connected in the other end of the collection box 7, and the spiral conveying rod 15 is located on one side of the through groove 16;

[0036] A first motor 5 is fixedly installed on one side of the collection box 7, and an output shaft of the first motor 5 is fixedly connected with one end of the spiral conveying rod 15;

[0037] The length of the end of the collection box 7 slidably connected with the pushing frame 19 is at least twice the length of the middle part of the pushing frame 19;

[0039] The second motor 8 is fixedly installed on one side of the collecting box 7, and an output shaft of the second motor 8 is fixedly connected with one end of the screw rod 20.

[0040] As can be seen, by starting the first motor 5 to drive the spiral conveying rod 15 to rotate, the silt and garbage falling into the collecting box 7 are conveyed into the push frame 19 of the inverted U-shaped structure through the spiral blades of the spiral conveying rod 15, that is, the silt and garbage are concentrated between the two vertical plates of the push frame 19, then when a large amount of silt and garbage are accumulated in the push frame 19, the first motor 5 is stopped to stop the spiral conveying rod 15 from conveying the silt and garbage into the push frame 19, then the second motor 8 is started to drive the screw rod 20 to rotate, so that the sliding block 18 moves along the screw rod 20 towards the end of the collecting box 7, thereby causing the push frame 19 to push the silt and garbage to move towards the end of the collecting box 7, since the length of the end of the collecting box 7 slidingly connected with the push frame 19 is at least twice the length of the middle of the push frame 19, when the push frame 19 completely moves in the collecting box 7, the end of the push frame 19 located on the outside always keeps the collecting box 7 and the filtering box 4 closed, when the end of the push frame 19 located on the outside moves to the outside of the collecting box 7, at this time, the end of the push frame 19 located on the inside has moved to the side of the end of the collecting box 7 rotatingly connected with the spiral conveying rod 15, so that the end of the push frame 19 located on the inside keeps the end of the collecting box 7 rotatingly connected with the spiral conveying rod 15 and the filtering box 4 closed, then as the push frame 19 moves, the silt and garbage in the push frame 19 are completely discharged from the collecting box 7, the end of the push frame 19 located on the inside is always in the collecting box 7, so that the filtering box 4 is always kept closed, so that the pump body 2 can continuously work to suck the accumulated water in the foundation pit into the filtering box 4 through the water suction pipe 6, then the second motor 8 reversely drives the screw rod 20 to rotate, so that the sliding block 18 drives the push frame 19 to move to the end of the spiral conveying rod 15, then the first motor 5 can be started again to drive the spiral conveying rod 15 to convey the silt and garbage into the push frame 19, so that the silt and garbage can be concentrated and discharged without stopping the water suction and drainage, the drainage efficiency is improved, and efficient drainage is realized.

[0041] Preferably, the end of the spiral conveying rod 15 and the end of the rotating disc 13 are coaxially fixedly provided with belt pulleys 21, and the two belt pulleys 21 are drivingly connected with a belt 22. Based on this, when the first motor 5 drives the spiral conveying rod 15 to rotate, the corresponding belt pulley 21 is driven to rotate, then the belt 22 is drivingly connected with the belt pulley 21 at the end of the rotating disc 13, thereby driving the rotating disc 13 to rotate, so as to reduce the use of driving equipment and reduce the manufacturing cost.
