Description

A water sample collector

technical field

The utility model relates to the technical field of water quality analysis and monitoring, in particular to a water sample collector.

Background technique

In the process of water quality analysis and monitoring experiments, it is often necessary to collect water samples to be tested, such as river water, river water and lake water. In some water bodies, the vertical pollution distribution is uneven, and water samples at different depths need to be collected.

The commonly used water sample collector adopts a transparent barrel structure. When collecting water samples, when the sampler sinks from the water surface, the water enters from the lower part of the sampler, flows out from the upper part, reaches the sampling depth, and retains the water column at the depth. The sampler is then pulled out of the water to collect a water sample. In this way, the pollutants in the upper water body will partially remain on the inner wall of the sampler, resulting in the phenomenon of pollutants hanging on the wall, causing the collected water samples to be unrepresentative.

Secondly, avoiding water sample sampler pollution is also a very important part of water quality investigation and monitoring. Otherwise, if the water samples taken are not representative, or the composition has changed, true and accurate experimental results cannot be obtained. Moreover, when a problem occurs, it is impossible to find out the source of the problem.

The existing bottle-type water sample collector starts to enter water at the target depth, but the sampling bottle cannot be sealed when the water intake device rises, and the upper water body may cause cross-contamination of the water sample during the lifting process.

In order to eliminate the pollution caused by the wall-hanging phenomenon of the upper water body, before the collector is put into the water and reaches the sampling target depth, water should be prevented from entering the collector. The water sample collector should be able to control the sealing and opening of the sampling bottle during collection.
