Stratified sampling device of surface water

Abstract

The invention discloses a stratified sampling device of surface water. The stratified sampling device of the surface water mainly comprises a sampling inner rod, a sampling bottle fastener, a sampling bottle, a sampling outer rod, a sampling bottle plug, a sampling bottle plug fastener, a clamping buckle 1, a clamping buckle 2, a sampling outer rod penetrating hole, a sampling inner rod penetrating hole, a clamping buckle hole 1, a clamping buckle hole 2, a clamping buckle 3, a sampling bottle plug rod and a sampling bottle rod. Sampling is conducted in the vertical direction of a water body, by means of a common stratified sampling device of the surface water, water samples usually are sampled in the vertical direction by several times, when the water body is sampled by several times, the disturbance to the water body is relatively large, and it cannot be ensured that sampling is conducted completely at the same point, the authenticity of the measured data is affected to a certain extent, and meanwhile, and fractional sampling increases the sampling workload. Therefore, the stratified sampling device of the surface water is designed and studied, and the device is simple in structure and convenient in operation, meanwhile, multiple groups of required water samples can be obtained in the vertical direction at the sampling point, and the disturbance to the water body is reduced.

Description

technical field [0001] The invention relates to the technical field of samplers, and more precisely relates to a layered sampling device for surface water. technical background [0002] Surface water detection experiments are often involved in production and scientific research activities, and it is inevitable to take samples of surface water when performing surface water detection. The samples and sampling methods are also different according to different experimental requirements. The common sampling method without special requirements is to directly store water samples in the water body. In some experiments, it is necessary to take samples in the vertical direction of the water body. Common surface water sampling devices usually take water samples in the vertical direction several times, which cannot satisfy the need to obtain the required water at a certain point in the vertical direction at the same time. In this way, taking water samples in batches disturbs the water ...

Problems solved by technology

In some experiments, it is necessary to take samples in the vertical direction of the water body. Common surface water sampling devices usually take water samples in the vertical direction several times, which cannot satisfy the need to obtain the required water at a certain point in the vertical direction at the same time. In this way, taking water samples in batches disturbs the water body greatly, and it cannot ensure that the samples are taken at the same point, which has a certain impact on the authenticity of the measured data. At the same time, sampling in batches also increases the sampling workload.
