[0023] It should be noted that the water in the pool is pumped into the inner cavity of the sorting cavity 102 in the box body 1, wherein the water in the pool is filtered by the first filter plate 203, and the live zooplankton stays in the inner cavity of the sorting cavity 102. With the filtration, the concentration of the live zooplankton in the inner cavity of the sorting cavity 102 increases. At this time, the servo motor 201 can slowly rotate the threaded column 202, and the first filter plate 203 can be moved upward by the threaded connection between the threaded column 202 and the first filter plate 203, so as to move the live zooplankton and water upward. In this process, the top column 208 will contact the connecting plate 207, thereby extruding the connecting plate 207 and the pressing plate 205 to slide into the inner cavity of the sleeve plate 204, so that the collection cavity 103 is opened, and then the high-concentration live zooplankton above the first filter plate 203 will enter the inner cavity of the collection cavity 103 with the water.

[0030] The water outlet pipe 403 is fixedly connected to the bottom of the box 1. The pump body is arranged on the side wall of the water outlet pipe 403.

[0031] It should be noted that: before the pool water enters the sorting cavity 102, it will fall on the surface of the third filter plate 4. Most of the pool water will be filtered by the third filter plate 4, and will flow out of the box 1 through the inclined plate 401 and the water outlet 402. The remaining part of the living and pool water will enter the sorting cavity 102, and the pool water will be preliminarily filtered. The filtering speed of the first filter plate 203 can be accelerated. The filtered water of the first filter plate 203 can be discharged through the water outlet pipe 403.

[0032] Operation mode: the pool water is pumped into the cavity of the box 1, and most of the pool water will be filtered by the third filter plate 4, and will flow out of the box 1 through the inclined plate 401 and the water outlet 402. The remaining part of the living and pool water will enter the sorting cavity 102, and the pool water will be filtered by the first filter plate 203, and the zooplankton living will stay in the cavity of the sorting cavity 102. As the filtering proceeds, the concentration of the living in the cavity of the sorting cavity 102 increases. At this time, the first filter plate 203 can be driven to move upwards by the threaded column 202 driven by the servo motor 201.
