Problems solved by technology

[0009] It can be seen that for shallow water areas with a water depth of less than 1m or exposed unconsolidated sediment, the problem of sampling with a sampling spoon is obvious. Since the upper part of the sediment is covered with a water layer of a certain thickness, the sediment samples and the sediment in the samples will be collected during the collection process. Composition produces a certain amount of loss; the most important thing is that a mixed sample is collected instead of a stratified sample, and the vertical distribution of contamination cannot be analyzed

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with specific embodiments.

[0024] The present invention has designed a kind of layered sampler of bottom mud of shallow water surface layer, with reference to figure 1 , comprising a sampling cylinder 10 and a handle 20, the sampling cylinder 10 is cylindrical, the upper bottom 101 is sealed, the lower bottom 102 is open, two through holes 103 are arranged in the middle of the sampling cylinder 10, the material of the sampling cylinder 10 is stainless steel, the sampling cylinder 10 Highly visible water depth and sampling depth vary between 30-150cm, and the diameter of sampling cylinder 10 also varies between 5-8cm depending on the sample demand (can be made into different specifications and models accordingly). Two through holes 103 with a diameter of 1 cm are arranged at a distance of 15 cm from the upper bottom, and the centers of the two through holes 103 are 3 cm apart to discharge air and wa...

Abstract

The invention discloses a shallow surface sediment layered sampler which comprises a sampling cylinder and a handle, wherein the sampling cylinder is of a cylindrical shape with a sealed upper bottom and an open lower bottom; and two through holes are arranged on the sampling cylinder. In order to study the accumulation, distribution, transformation and migration laws of pollutants discharged into water in the sediment, the sediment samples need to be collected. For conventional sampling, when the water depth at the sampling position is less than 1 m, the sampling is performed in water by use of a sampling scoop. Sampling with the sampling scoop has two shortcomings that: some components of the sediment samples are lost when the samples pass through the water, and the layered samples cannot be collected. Through the invention, the two shortcomings of the method are completely solved.

Description

technical field [0001] The invention relates to a small sediment sampler for lakes and rivers, which is used for sampling surface sediment in shallow water areas below 1m in depth, and is especially suitable for collecting layered samples of surface sediment and unconsolidated sediment without water coverage sampling. Applicable to the field of environmental protection and water resource management departments, it is used to study the accumulation, distribution, transformation and migration of pollutants discharged into the water body in the sediment, analyze the vertical distribution of pollution, and understand the pollution characteristics during the formation of the sediment. Background technique [0002] Sediment refers to water body sediment. In order to study the accumulation, distribution, transformation and migration of pollutants discharged into the water body in the sediment, it is necessary to collect sediment samples. [0003] Sediment is usually a mixture of ...
