Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage detection sampling, in particular to a sample bottle state detection device in a sewage sampler. Background Technique
[0002] In the fields of environmental protection and sewage treatment, the accurate detection and analysis of sewage are crucial. And sewage sampling is a key link in the whole detection process. Traditional sewage sampling methods often have many problems. For example, it is difficult to ensure the tightness of the sample during the sampling process, which easily leads to external contamination of the sample and affects the accuracy of the detection results.
[0003] At the same time, the monitoring methods for the placement state and liquid level of the sample bottle are relatively backward, and it is impossible to master the situation of the sample bottle in real time and accurately. In previous sampling devices, due to the lack of effective detection components, it may not be possible to timely detect whether the sample bottle is placed in place and accurately control the liquid level height in the sample bottle.
[0004] In addition, due to the lack of a perfect sealing component, during sampling and storage, the sample may leak, or external impurities may enter the sample bottle, thus destroying the original properties of the sample.
[0005] To sum up, in order to improve the accuracy, reliability and safety of sewage sampling, it is particularly important to develop a sewage sampler with an advanced sample bottle state detection device. For example, in some industrial wastewater treatment scenarios, due to the complex composition of the wastewater, the requirements for sampling are higher. If the sampling volume cannot be accurately controlled and the tightness of the sample cannot be ensured, accurate data support cannot be provided for the subsequent treatment process. Therefore, a sample bottle state detection device in a sewage sampler is proposed for the above problems. Content of the Utility Model
