and the telescopic connecting piece 3 is used for connecting two adjacent catching assemblies 4.
In the embodiment of the invention, the whole length of the collecting mechanism 2 can be adjusted through the flexibility of the telescopic connecting piece 3, and then the collecting mechanism is fixed at the bottom of the stream through the fixing mechanism 1, so that the catching assemblies 4 can be relatively uniformly distributed in the whole width range of the stream, the collecting effect is better, the collecting mechanism can adapt to streams with different widths, and the flexibility is extremely high.
As shown in fig. 3 and 6, as another preferred example of the present invention, the catching assembly 4 includes a first collecting case 401 and a second collecting case 403 disposed on the first collecting case 401, one end of the second collecting case 403 close to the first collecting case 401 is provided with a second filter plate 404, one end of the first collecting case 401 far from the second collecting case 403 is provided with a first filter plate 402, and the mesh number of the first filter plate 402 is smaller than that of the second filter plate 404.
In practical situations, because of different requirements for experiments on plankton, plankton with different particle sizes need to be classified, and a lot of time needs to be consumed, a first filter plate 402 is fixed at one end of the first collecting shell 401 far away from the second collecting shell 403, a second filter plate 404 is fixed at one end of the second collecting shell 403 close to the first collecting shell 401, plankton with different particle sizes are collected through the difference of different mesh numbers of the first filter plate 402 and the second filter plate 404, the problem that the plankton needs to be classified again in the later period is avoided, and a lot of time is saved.
In a case of this embodiment, the telescopic connection member 3 is preferably a corrugated pipe, and the material is preferably stainless steel, so that the telescopic connection member 3 has certain flexibility, and the collision of sundries to the capturing component 4 or the telescopic connection member 3 is avoided, and the telescopic connection member 3 cannot flexibly adjust the position, thereby causing damage.
