Description

Sediment sampler

Technical Field

The utility model relates to the technical field of hydraulic engineering, in particular to a sediment sampler.

Background

At present, during construction of hydraulic engineering, components of sediment in a river channel are usually detected and analyzed, and the sediment is usually formed by depositing clay, sediment, organic matters and a mixture of various minerals on the land surface or at the bottom of a water body through the actions of long-time physics, chemistry, biology and the like and water body transmission. Currently, in hydraulic engineering, in order to detect scientific researches of hydraulic geology, it is often required to sample bottom mud in river water.

In the bottom mud sampler in the prior art, a sampling tube is usually inserted into bottom mud of the water for sampling, and is directly taken out after sampling, and as a sampling port is not sealed, a sampled bottom mud sample is easily diluted or eroded by river water in the process of taking out the bottom mud sample from the water, so that the sampled sample breaks the original property of the bottom mud, and the accuracy of a sampling detection result is affected. Therefore, we provide a sediment sampler for hydraulic engineering.

According to the utility model, not only can the bottom mud of the water be conveniently and rapidly sampled, but also the sampling notch at the bottom side of the sample storage tank can be rapidly plugged through the plugging valve ball, so that the condition that the sample is easily diluted or corroded by river water in the process of taking out the sample from the water due to the fact that the sampling port is not plugged and sealed in the prior art is avoided, the original property of the bottom mud sample can be ensured not to be damaged, and the accuracy of a sampling detection result is ensured.

Above-mentioned bed mud sampling device has increased the airtight structure of sample, but because the bed mud of water sample environment is its concentration is bigger more, and mobility is lower more, and the sample through the sampling through-hole just can not realize in this structure, can't sample the bed mud of different degree of depth, leads to the sample effect of bed mud sampler relatively poor, and the practicality is low, consequently, this application provides a bed mud sampler and satisfies the demand.
