Description

[0002] When conducting municipal sewage treatment, it is necessary to first sample and analyze the sewage, and then formulate a sewage treatment process. Since municipal sewage is generally a sewer pipe, staff generally conduct sampling through manual operation, which will consume the staff's physical strength. At the same time, the sampling efficiency is low, and the sampling device is not easy to disassemble, which makes it difficult to carry and creates a burden on the sampling personnel.

[0003] In the prior art, a Chinese utility model patent with announcement number CN212432678U discloses a sampling device for sewage treatment, which extracts sewage by setting a suction cup and a plug, and then uses the cooperation of two one-way valves to transfer the sewage in the suction cup to a cup, which is convenient to use. However, in actual operation, the output pipe needs to be disassembled and assembled, which is relatively troublesome to operate. After the output pipe is installed, the lateral space occupied by the output pipe is large, which is inconvenient to operate. After the suction cup extracts the sewage sample, it needs to be moved again to a position close to the cup before the sewage can be transferred to the cup. The steps are relatively complicated and the use is somewhat inconvenient. Utility Model Content
