Multi-sampling device for water quality detection

Abstract

The invention belongs to the technical field of water quality detection, and particularly relates to a multiple sampling device for water quality detection, which comprises a box body, four groups of glass bottles are fixedly mounted in an inner cavity of the box body, the four groups of glass bottles are fixedly connected side by side, and the outer wall of the glass bottle positioned on the outer side is fixedly connected with the side wall of the inner cavity of the box body. The negative pressure pump can generate negative pressure in the glass bottles, so that water can be introduced into the glass bottles, meanwhile, the multiple glass bottles are arranged, single sampling can be carried out separately, the situation that the later detection precision is affected due to water source doping is effectively avoided, multiple sampling is achieved, and the detection efficiency is improved. Meanwhile, a plurality of glass bottles are arranged in the inner cavity of the box body, so that the device can be effectively protected, and the device is compact in overall structure, small in size and convenient to carry and store.

Description

technical field [0001] The invention relates to the technical field of water quality detection, in particular to a multiple sampling device for water quality detection. Background technique [0002] The purpose of water quality inspection is to investigate the environmental quality, to study whether the water quality is suitable or suitable for use, to investigate the pollution or the degree of pollution of the water, and to check the efficiency of the water treatment process, etc. The inspection items of water samples (which can be called water quality parameters) depend on the purpose of inspection and the nature of water samples. The resulting data should be evaluated comprehensively to illustrate water quality. [0003] Before the existing water quality testing, the water source needs to be sampled, so the sampling device needs to be used. The structure of the existing sampling device is relatively simple. When some multi-point sampling is required, the sampling device ...

AI Technical Summary

Problems solved by technology

[0003] Before the existing water quality testing, the water source needs to be sampled, so the sampling device needs to be used. The structure of the existing sampling device is relatively simple. When some multi-point sampling is required, the sampling device needs to be used repeatedly. The water from the previous water source will remain in the sampling device, so that it will be mixed into another set of water samples when sampling again, which will affect the accuracy of the final detection. At the same time, the existing sampling device does not have the sealing effect after use, so Dust is easy to enter, and it is easy to affect the effect of later use
