Problems solved by technology

Most of the existing stratified sampling systems for water samples use the above-mentioned structure. Although the simple stratified effect can be achieved, the structure is too complicated, the production cost is high, and it is troublesome to use, and it cannot be accurately stratified. Deep water quality samples cause great inconvenience, which is not only inconvenient to use, but also prone to deviation due to inaccurate stratification, and the use of telescopic rods to collect water quality limits the maximum depth that can be collected

Abstract

The invention discloses a stratified sampling system, and aims to provide a stratified sampling system which is simple in structure, precise in control and capable of achieving stratified sampling. The stratified sampling system comprises a base and support racks, wherein the support racks are mounted at two side ends of the base; helix roller is mounted between the support racks; a sampling tube matched with the helix roller is arranged on the helix roller; servo steering engines connected with the helix roller are arranged on outer end surfaces of the support racks; a vacuum rotating connector communicated with the sampling tube is arranged inside the helix roller; a peristaltic pump communicated with the vacuum rotating connector is further arranged on the base; a water outlet is formed in the peristaltic pump; a water outlet tube is arranged at the water outlet. The stratified sampling system is applied to the technical field of water quality sampling.

Description

technical field [0001] The invention relates to a sampling device, in particular to a layered sampling system. Background technique [0002] With the growth of world population and the development of industrial and agricultural production, water consumption is also increasing. At the same time, due to the production and life of human beings, the surface and underground water bodies are polluted, and the water quality deteriorates, which makes the limited water resources more tense. In the case of such a shortage of water resources, we must cherish water resources more, and at the same time, the testing department should do a good job in testing to provide protection for the health of the people. Water testing is a matter of people's livelihood and should not be underestimated. [0003] Therefore, it is necessary to carry out layered detection of water quality such as rivers. Most of the existing telescopic rods are used to realize the detection of water quality layers. Th...
