Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples

As shown in fig. 1-4, the portable multi-point river sampling mechanism comprises a water taking frame 1, wherein a plurality of sampling cylinders 2 are arranged on two sides of the water taking frame 1, the outer ends of the sampling cylinders 2 are connected with an L-shaped liquid taking pipe through a connector 3, a transverse pipe 41 of the liquid taking pipe is positioned inside the connector 3 and is in sliding connection with the connector 3 in a matching manner, the transverse pipe 41 is communicated with the sampling cylinders 2, and the bottom end of a longitudinal pipe 42 of the liquid taking pipe extends into water; the bottom end of the longitudinal pipe 42 is provided with a conical part 43, the conical part 43 is provided with a water inlet 44, a valve ball 45 for sealing the water inlet 44 is arranged in the conical part 43, the valve ball 45 is connected with the water inlet 44 through a compression spring 46, and the length of the longitudinal pipe 42 on each sampling cylinder 2 is unequal.
