Description

Technical Field

[0002] Water is the source of life. Human beings cannot live without water in their lives and production activities. The quality of drinking water is closely related to human health. With the development of social economy, scientific progress and the improvement of people's living standards, people's requirements for the quality of drinking water are constantly increasing, and the drinking water quality standards are also constantly developing and improving accordingly. Since the formulation of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and their water quality status, there are differences in the requirements for drinking water quality, so personnel are needed to test the water quality.

[0003] At present, when testing water quality, people usually take samples for testing. The water quality samples need to be placed in containers and then temporarily stored and transported using storage devices. Existing sample storage devices do not have the effect of low-temperature preservation, which causes the water quality samples to easily deteriorate due to excessively high temperatures during storage and transportation, thereby causing inaccurate water quality test results. At the same time, the sample storage device is not convenient for fixing the water quality samples during use, which causes the water quality samples to easily tilt, be damaged, and be lost during transportation, resulting in reduced efficiency in water quality testing.
