Embodiment Construction

[0017] The invention relates to the fields of water quality monitoring, environmental protection and the like, and is a tool capable of safely and effectively protecting the quality of sampling water, that is, a sampling and preserving device for water quality monitoring samples. By vacuuming the internal environment of the sampling bottle and adding inert gas, not only the water quality of the sample can be effectively protected. At the same time, it is also possible to take multiple samples at different depths and different distances and process them in batches without affecting the water quality. In this way, the tested water quality can be efficiently, conveniently and environmentally friendly obtained.

[0018] see figure 1 , the concrete structure of a kind of water quality monitoring sample sampling preservation device that the present invention relates to is:

[0019] Including a sampling bottle body 2, a vacuum pump 8 and a gas cylinder 10; wherein, the top and bott...

Abstract

The invention relates to a sampling and preserving device used for water quality monitoring samples. The sampling and preserving device comprises a sampling bottle body (2), a vacuum air pump (8) and a gas cylinder (10); the top part and the bottom part of the sampling bottle body (2) are provided with a first gas valve (1) and a second gas valve (4) respectively; the vacuum air pump (8) and the gas cylinder (10) are provided with a third gas valve (7) and a fourth gas valve (9) respectively; the second gas valve (4) is respectively connected to the third gas valve (7) and the fourth gas valve (9) via a flexible pipe (5), a flexible pipe joint (6) and a 3-way valve (11). The sampling and preserving device is capable of obtaining samples used for water quality testing with high efficiency and convenience and without pollution.

Description

technical field [0001] The invention relates to a device for sampling and preserving water quality monitoring samples. Background technique [0002] In the fields of water quality monitoring and environmental protection, the water quality monitoring of oceans, rivers, lakes, reservoirs and other waters has always been the focus of environmental protection. However, although some parameters such as PH value, oxygen content, microbial content, etc. can be manually monitored on-site through some portable monitoring during water quality monitoring. Similarly, the trend of water pollution is becoming more and more serious nowadays. In many cases, it is necessary to collect different polluted water quality and then return it to the laboratory for analysis. This not only has high requirements on the sampling location and sampling method; and the existence of samples will increase with time, due to factors such as oxidation and chemical reactions, the water quality in ordinary samp...
