When the water collecting well is used, when the water in the water collecting well gradually descends, the buoyancy force borne by the frame 31 gradually decreases, and then the acting force on the steel wire rope gradually increases, so that the rotating shaft 36 is driven, the bolt 81 can quickly reach the other notch 83 from the one notch 83, and the sealing plate 6 timely closes the filter screen 313; when the water level in the water collecting well increases, the buoyancy force applied to the frame 31 gradually increases, and the latch 81 does not act until the buoyancy force can be equal to the gravity force of the frame 31, so that the sealing plate 6 is opened and water is fed into the frame 31, and the action switching frequency of water suction and stopping can be reduced through the hysteresis mechanism 8. The sensor for detecting the rotation position of the rotating shaft 36 can be arranged on the rotating shaft 36, and the submersible pump 32 and the water pump 21 are started and stopped through the position of the rotating shaft 36, so that water in the water collecting well can be pumped and discharged in time.
