Description

technical field

The utility model relates to a sampler, in particular to a columnar sediment sampler.

Background technique

Since sediments are of great significance for revealing environmental changes, depositional processes, and pollutant migration, it is necessary to maintain the original characteristics of sediment types and depositional sequences as well as possible during sampling. At present, sediment samplers are mainly divided into two types: grab type and column type. The grab type sampler has a simple structure, but it has a large disturbance to the sample, the sampling depth is limited, and there is a problem of sample loss due to low airtightness. Used to collect surface samples of sediment; columnar samplers are used to obtain sediment samples by inserting vertically into the sediment. Generally, the columnar sampler has a complex structure and a large volume, and requires an external power supply and is relatively expensive; some columnar samplers with a simple structure usually lack an effective sediment sealing device at the bottom of the sampling tube, so that the sediment is trapped when the sampler is pulled out.
