Embankment-traction fixed-point-rotation pond bottom sewage discharging device

The utility model discloses an embankment-traction fixed-point-rotation pond bottom sewage discharging device and belongs to the technical field of prawn cultivating equipment. The embankment-traction fixed-point-rotation pond bottom sewage discharging device consists of a sewage collecting circular trough, a rotary sewage discharging component, an underground sewage discharging passage, a water stopping part and a traction device, wherein the sewage collecting circular trough consists of a sewage collecting ring, a ring body, a fixing post and a rotary hole plate; the bottom surface of the sewage collecting ring is designed into a lower middle part and a higher periphery; and the slope is 3-5%. The embankment-traction fixed-point-rotation pond bottom sewage discharging device has the advantages of simple structure and convenience for use; an operator can rotate the sewage discharging device arranged in the center of a pool at a fixed point by pulling a traction rope back and forth on an embankment, so as to discharge sewage rotated into the sewage collecting circular trough by an aerator out of the pool relatively completely and quickly, so that the embankment-traction fixed-point-rotation pond bottom sewage discharging device is safe, time-saving and labor-saving, water is stopped and drained conveniently, and the operator can stop and drain water on the embankment; and the material sources are wide and all the materials are from daily life.
