Description

Technical Field

[0001] The invention relates to the technical field of sewage detection and sampling, in particular to a sample bottle state detection device in a sewage sampler. Background Art

[0002] In the field of environmental protection and sewage treatment, accurate detection and analysis of sewage is crucial. Sewage sampling is a key link in the entire detection process. Traditional sewage sampling methods often have many problems. For example, it is difficult to ensure the sealing of the sample during the sampling process, which easily leads to external contamination of the sample and affects the accuracy of the test results.

[0003] At the same time, the monitoring methods for the placement status of the sample bottle and the liquid level are relatively backward, and it is impossible to grasp the status of the sample bottle in real time and accurately. In previous sampling devices, due to the lack of effective detection components, it is impossible to detect whether the sample bottle is placed in place in time, and it is impossible to accurately control the liquid level in the sample bottle.

[0004] In addition, due to the lack of a perfect sealing component, during the sampling and storage process, the sample may leak, or foreign impurities may enter the sample bottle, thereby destroying the original properties of the sample.

[0005] In summary, 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 status detection device. For example, in some industrial wastewater treatment scenarios, due to the complex composition of wastewater, the sampling requirements are higher. If the sampling volume cannot be accurately controlled and the sealing of the sample cannot be guaranteed, it will not be possible to provide accurate data support for the subsequent treatment process. Therefore, a sample bottle status detection device in a sewage sampler is proposed to address the above problems. Summary of the invention
