When the water flows into the water collection tank 6 through the water pipe 406, part of the water flow will directly enter the filter 604. After the filter 604 is filled with water, the remaining water will remain above the fixed plate 601. At this time, plankton will be affected by the flow of water. The driving effect is accumulated on the inner wall of the filter screen 602. When the water on the fixed plate 601 reaches a certain capacity, the control box 2 will start the nozzle 603, and the nozzle 603 will spray the water to the filter screen 602, allowing the plankton to enter the filter below. 604, and then discharged through the valve 6041.
