[0028] Working principle: When in use, the whole device is installed on the ground, and the water conservancy pipeline 100 is set as the water inlet end, and is connected to the external water conservancy engineering pipeline through the mounting ring 101 with the help of external bolts. When water enters through the left end of the water conservancy pipeline 100, it will pass through the two filter screens 11 in sequence.

[0029] During use, the solar panel 3 absorbs external solar energy and converts it into electrical energy and stores it in the battery. The inverter 7 converts direct current into alternating current to power the time-controlled switch 6, the first drive motor 5, the multi-stage electric telescopic rod 4 and the second drive motor 19. The opening and closing time of the first drive motor 5, the multi-stage electric telescopic rod 4 and the second drive motor 19 are set by the time-controlled switch 6. When the time for cleaning sludge impurities is reached, the time-controlled switch 6 first controls the multi-stage electric telescopic rod 4 to open in the forward direction, and the output shaft of the multi-stage electric telescopic rod 4 drives the second blocking plate 1 to move downward through the connecting block to clean the sludge impurities. The left end of the pipe 100 is blocked to stop the water flow from entering. After an interval of ten seconds, the timer switch 6 controls the second drive motor 19 to turn on in the forward direction. The output shaft of the second drive motor 19 drives the screw 14 to rotate. Under the action of the threaded hole provided on the moving block, the screw 14 drives the moving block to move to the right while rotating. The moving block drives the first blocking plate 18 to move to the right. The first blocking plate 18 moves to the right while releasing the blockage of the two tapered guide holes 15. Ten seconds after the second drive motor 19 is turned on, the timer switch 6 controls the second drive motor 19 to turn off and controls the first drive motor 5 to turn on. The first drive motor The output shaft of 5 drives the reciprocating screw 9 to rotate. Under the action of the reciprocating wire hole opened on the U-shaped rod 8, the reciprocating screw 9 rotates to drive the U-shaped rod 8 to move up and down in a cycle. The U-shaped rod 8 drives two push plates 10 to move up and down in a cycle. When the push plates 10 move downward, they push the impurities and sludge blocked on the left side of the corresponding filter screen 11 downward. Under the pushing force, the impurities and sludge fall into the corresponding conical guide holes 15. At the same time, multiple exciters 17 are turned on. The exciters 17 excite the corresponding discharge pipes 16 to vibrate. Under the vibration force, the impurities and sludge inside the conical guide holes 15 are discharged to the outside through the discharge pipes 16. When 10 reciprocates up and down for one stroke, the time-controlled switch 6 controls the first drive motor 5 to close, and then the time-controlled switch 6 controls the multi-stage electric telescopic rod 4 to start in reverse, so that the second blocking plate 1 is transformed to move upward, and at the same time controls the second drive motor 19 to start in reverse, so that the first blocking plate 18 is transformed to move to the left to block the two conical guide holes 15 again. The time-controlled switch 6 also controls the multiple vibrators 17 to close. At this time, water continues to enter the water conservancy pipeline 100, thereby achieving the purpose of automatically cleaning and discharging the filtered sludge impurities at a regular time, without the need for manual cleaning by personnel, reducing labor intensity and improving cleaning efficiency.
