[0041] In the sand flushing groove 4, multiple groups of photoelectric sediment meters monitor the sediment deposition in real time. When the sediment accumulates to a certain height, the automatic induction gate will automatically open the sand flushing port 3 according to the signal of the sediment meter, allowing the sediment to be discharged through the sand flushing port. The sand discharge port 2 is opened after the sand flushing port 3 is closed, to ensure that the water flow does not carry sediment into the downstream during the sand flushing process.
