When sampling is to be carried out, the handle of the sampler is grasped, the sampling location of the sampler is fixed, the controller starts the motor, the threaded rod moves downward, and when the specified sampling depth is reached, the electric telescopic rod is extended and retracted, so that the rubber plate moves up and down to leave the sampling port, and at the same time, the rotating shaft drives the arc plate to move along the wave groove to clean the attachments on the surface of the filter shell, further reducing the impact on the sampled water, and at the same time, the bristles move up and down elastically, making it easier to clean the filter shell, and the sampled water enters different inner cavities of the sampling tank respectively. After the sampling reaches a certain number, the electric telescopic rod is retracted, so that the rubber plate blocks the sampling port and stops the entry of the sampled water. The motor rotates the threaded rod to retract and take away the sampler. When reaching the analysis area, the filter shell is disassembled, the water outlet is opened, and the sampled water is taken away for analysis.

[0027] In addition, in order to increase the number of samples, the number of rubber plates 505 and partition plates 506 is set to three, and the three rubber plates 505 and partition plates 506 are arranged in a linear array in the inner cavity of the sampling tank 503, and the three groups of rubber plates 505 and partition plates 506 fit the inner cavity of the sampling tank 503, so that the sampled water is more in line with reality and avoids contingency.
