Preferably, the area of the opening part is larger than that of the liquid inlet.
Preferably, the liquid inlet is circular, triangular, quadrilateral or key-shaped.
Preferably, the openings are independent from each other and do not communicate with each other.
Preferably, the length of the sampling tube is longer than that of the cover tube.
The utility model has the beneficial effects that:
(1) when the sampler is used for sampling a water sample, firstly, the whole sampler is vertically arranged in a water area to be sampled, secondly, the protective cylinder is faded down from the covering cylinder, then the covering cylinder rotates around the sampling cylinder after the sampling cylinder is fixed, and further, the opening part is communicated with the liquid inlet; the sampled sample is stored in the sample containing chamber; after sampling is finished, the covering cylinder rotates around the sampling cylinder again to completely stagger the opening part and the liquid inlet, so that the sample containing cavity is sealed; and finally, taking the sampling cylinder and the covering cylinder out of the water area to finish the sampling operation.
(2) The sampler can simultaneously take multiple water samples from different depth positions by one-time sampling, so that the labor intensity is greatly reduced, and the sampler plays a role in reducing the water samples from entering the sample containing cavity when the sampling cylinder and the cover cylinder enter water at the beginning of sampling through the arrangement of the protective cylinder, and the protective cylinder is removed after the sampling cylinder is positioned, so that the water quality mixing is avoided to the maximum extent, and the detection precision is improved.
