[0026] Working principle: When the utility model is working, the first motor 19 is started to drive the convex rotating wheel 20 to rotate. Under the rotation of the convex rotating wheel 20 and the elastic force of the first spring 17, the second push plate 16 drives the first push plate 14 fixedly connected to the other end of the connecting rod 13 to reciprocate in the left and right directions. Under the action of gravity and pressure, the second T-block 6 is alternately moved to extract the water source. When foreign matter enters the U-tube 21 and is pushed under the filter screen 26 by the water flow, the filter screen 26 is driven by the thrust to slide the rack 28 fixedly connected to the slide frame 24 upward. The upward sliding of the rack 28 drives the gear 29 to rotate. The rotation of the gear 29 drives the rear turntable 32 to rotate. The rotation of the turntable 32 causes the fixed button 33 to trigger the control switch The control switch 34 transmits a signal to the controller 35. The controller 35 receives the signal to control the first motor 19 to close and start the second motor 36. The start of the second motor 36 drives the threaded rod 38 to rotate. The rotation of the threaded rod 38 drives the threadedly connected sliding block 41 to move in the relative direction. The movement of the sliding block 41 drives the friction block 42 to move so that the fixed turntable 37 remains stationary. The fixed turntable 37 drives the convex rotating wheel 20 on the rear side to remain stationary, thereby stopping the work of the water pump in time until the foreign matter falls into the collection box 44 through the foreign matter opening 43. Under the elastic force of the second spring 23, the sliding frame 24 returns to its original position, so that the gear 29 drives the turntable 32 to trigger the control switch 34. The control switch 34 controls the controller 35 to make the water pump continue to work normally.
