When the rubber sealing seat 14 moves upward, the air inside the sampling tube 9 is extracted, so that the sewage can enter the interior of the sampling tube 9. When a certain amount of sampling is taken, the linear motor 3 is controlled to make the movable seat 5 drive the sampling tube 9 to rise to the original position, and then the motor 6 is turned on to make the motor 6 drive the sampling tube 9 to rotate a certain angle, and then the cylinder 10 is controlled to shrink the telescopic rod 1002, so that the piston rod 13 is pushed to move by the pushing seat 12, so that the rubber sealing seat 14 can squeeze out the sampled water.
