Technical Field

[0001] The utility model relates to the technical field of wastewater collection, in particular to a telescopic wastewater sampler. Background Art

[0002] The purpose of wastewater sampling is to monitor and evaluate the quality of wastewater to ensure that wastewater discharge complies with environmental protection standards and regulations. It can help monitor wastewater discharge. By sampling and analyzing wastewater, it can be determined whether wastewater treatment facilities can effectively remove pollutants in wastewater to meet environmental protection standards. It can promptly detect and resolve whether wastewater contains harmful substances. Wastewater samplers are basically used in wastewater sampling.

[0003] However, the traditional telescopic sampler relies on a peristaltic pump and a hybrid stepper motor drive to sample wastewater. During sampling, the wastewater contains many impurities and large garbage, which results in incomplete collection of sewage and makes it difficult to filter the impurities inside the sewage. During sampling, it is very easy to sample the impurities and particles in the wastewater together, which makes it difficult to clean up later.

[0004] Therefore, it is necessary to provide a new telescopic wastewater sampler to solve the above-mentioned technical problems. Utility Model Content
