[0002] Environmental testing is an important part of environmental protection work. It monitors and evaluates environmental quality through a series of scientific methods and means to understand environmental conditions and changing trends. When testing and sampling sewage, a sampling device is required.

[0003] After searching, the announcement number is CN211697095U, and the name is a sewage sampling device for environmental protection testing, including a handle. Through research and analysis, it is found that although it has the advantages of reasonable structure, easy to carry, and high sampling efficiency during use, it still has the following disadvantages to a certain extent.

[0004] For example, it does not have a partitioned storage function, and cannot partition and store sewage from different environments. As a result, when sampling sewage from different environments, staff need to carry multiple sampling devices, which affects the subsequent detection efficiency. At the same time, it does not have a cleaning function. After the sewage is discharged, the inner wall of the sampling tube cannot be quickly cleaned, causing impurities to easily adhere to the inner wall of the sampling tube, which in turn affects the next sampling operation and test results. In order to solve the above technical problems, we have designed a sampling device for environmental protection detection. Utility Model Content
