[0043] In the implementation process, when the conical net 444 is put into the lake water and moves in the 8-shaped reciprocating path in the water, the water and plankton in the lake will be passively entered into the conical net 444, because the lower end of the conical net 444 is connected with the cylinder 51, so that the water and plankton will enter the cylinder 51 in the movement process of the conical net 444, the water pressure at this time will extrude the spherical ball 534 to move backward, the spring telescopic rod 532 will be in a compressed state, so that the inner surface of the conical groove rod 531 is connected with the inner surface of the conical net 444, the movement of the conical net 444 will make the water and plankton enter from the conical net 444 and be discharged from the lower end of the conical net 444, so as to realize the flow of water and plankton.

[0044] Secondly, after the water and plankton enter the cylinder 51, the plankton in the water is classified according to the size under the filtering effect of the two filter screens 521, the large plankton is retained in the space formed by the upper filter screen 521 and the cylinder 51, and the small plankton passes through the round holes 523 on the upper filter screen 521 and the bottom frame 522 on the upper part to the lower filter screen 521, and the lower filter screen 521 retains the small plankton, so that the sorting of the plankton is realized, the water pressure generated by the movement promotes the flow of the water and the plankton in the device, the double-layer filter screen 521 can separate the plankton of different sizes through the difference in hole diameter, the separation of the plankton of different sizes can be completed at one time, the complicated sorting after mixing the sample is avoided, the sample processing efficiency is improved, the sample transfer loss is reduced, the plankton of different sizes is completely retained, the samples of the plankton of different sizes are independently preserved after sorting, clear and pure samples are provided for subsequent classification and identification and ecological research, and the analysis of the community structure and ecological function of the plankton in the lake is facilitated.

[0048] In the implementation process, when the collection is completed, the conical net 444 is lifted away from the lake, then the water in the conical net 444 flows out through the holes of the conical net 444, and the remaining water and plankton are retained in the cylinder 51. When it is necessary to collect samples of plankton of different sizes, at this time, the two collection bottles 549 are respectively threadedly connected to the inner surfaces of the connecting blocks 5410, then the push rod one 543 and the push rod two 544 are pushed to slide upward, the circular plate 5411 is driven to move upward, the reset spring 548 is in a compressed state, and the two blocking blocks 547 are respectively away from the upper ends of the communication pipe one 545 and the communication pipe two 546, then the sorted plankton and water enter the two collection bottles 549 through the communication pipe one 545 and the communication pipe two 546 respectively, the sample is stored in different zones, the mixing of plankton samples of different sizes and types is effectively avoided, the sample in the collection bottle 549 has high consistency, which is convenient for subsequent research, cross contamination and sample loss in the process of manual sample transfer are reduced, the standardization and effectiveness of sample storage are improved, and a more scientific and reliable sample basis is provided for the research of lake plankton.
