Then, the three-way ball 5 is rotated by the drive mechanism to close the sampling mechanism, and the rinsing water is used to clean the collection head 4. The sewage is discharged into the collection tray 21, completing the cleaning of the pipe. The collection tray 21 is moved manually along the sliding groove 22 and removed to facilitate sewage treatment.
