Description

Technical Field

[0001] The utility model belongs to the technical field of sampling devices, in particular to a quantitative sampling device for groundwater quality analysis. Background Art

[0002] The quantitative sampling device used for groundwater quality analysis is a device specially designed to accurately collect a certain amount of groundwater samples for water quality analysis. It usually consists of a sampling container, components for controlling the sampling volume, anti-pollution and sealing structures, and related devices for extracting and storing samples. Its working principle is to ensure that the amount of each sampling is accurate and stable through a specific control mechanism, while minimizing the contamination of water samples by external factors to the greatest extent, ensuring the authenticity and representativeness of the collected water samples. In practical applications, this device can provide a reliable sample basis for the scientific analysis of groundwater quality, help to accurately understand the content, composition and characteristics of various substances in groundwater, and thus provide important data support for the protection, utilization and management of groundwater resources.

[0003] Existing water quality sampling devices have obvious defects in the actual sampling process. Since various substances in the water will precipitate under specific conditions, the substances contained in the collected water samples are not complete. For example, some heavier particulate matter may have settled to the bottom before sampling and cannot be collected in the sample. The occurrence of this situation makes it impossible for us to obtain complete information about the substances in the water, and thus it will be impossible to conduct a comprehensive and accurate in-depth analysis of the composition, properties and quality of groundwater. Utility Model Content

[0004] The purpose of the utility model is to provide a quantitative sampling device for groundwater quality analysis, which solves the problem that various substances in the water will precipitate under specific conditions, which leads to incomplete substances contained in the collected water samples.

The occurrence of this situation makes it impossible to obtain complete information about the substances in the water, and thus it will be impossible to conduct a comprehensive and accurate in-depth analysis of the composition, properties and quality of groundwater.
