Liquid sample storage device for environmental monitoring

Abstract

The invention discloses a liquid sample storage device for environmental monitoring, which comprises an oscillation reducing module, an environment adjusting module and a PH value adjusting module, damping mechanisms are mounted on two sides of a test tube support frame, the other ends of the damping mechanisms are fixedly connected with a storage box, and the environment adjusting module and a control unit are arranged on two sides of the test tube support frame. The environment adjusting module is used for adjusting the internal environment of the storage box, a timer is mounted in the control unit, and an oscillation reducing module is mounted at the top of the sampling test tube; according to the liquid sample storage device for environmental monitoring, the arranged vibration reduction module is used for sealing and transferring sampling test tubes, the situation that substances in liquid cannot be naturally precipitated due to shaking of the sampling test tubes during transferring is avoided, and the standing and precipitating time of collected samples is saved; a preservative is injected into liquid in the sampling test tube through the PH value adjusting module, so that the PH value is automatically adjusted, and the accuracy of detection data is ensured.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to a liquid sample storage device for environmental monitoring. Background technique [0002] As an indispensable basic resource in the natural environment, water has played a huge role in promoting the development of fire-based social civilization. Testing the water quality environment and preventing and controlling its pollution have become an important link in improving the ecological environment. Similarly, mastering accurate and efficient The collection and preservation of water quality environmental samples is of great significance for maintaining people's basic life and social production activities. Quality control is the core content of water environment monitoring, mainly based on the process of sample collection to preservation, and the accurate performance of monitoring data. It reflects the environmental quality of the monitored waters and helps to implement the f...

[0004] However, in order to prevent the added preservative from affecting the properties of the test sample, it is generally necessary to let the sample stand for 30 minutes after collection, and then drop the preservative after the natural precipitation is complete. This setting greatly increases the sampling time and transportation time. , Delay the work process, and when the waste water is collected at the same time, the waste water sample will slowly overflow harmful gases to the liquid surface of the collection test tube, such as hydrogen sulfide, hydrogen cyanide, carbon monoxide, carbon dioxide and other gases, because these gases generally form in the human body The function is to inhibit the oxygen exchange ability of the internal tissues or cells of the human body, causing asphyxiation poisoning due to the hypoxia of the human body tissue. When testing in the laboratory, the sample test tubes need to be opened sequentially for sampling testing, and a large amount of harmful gas will overflow, affecting the life of the testing personnel. health, for this purpose, we propose a liquid sample storage device for environmental monitoring
