The outer wall of the anti-fouling pipe 32 is tightly attached to the inner wall of the sampling pipe 31, the two ends of the anti-fouling pipe 32 extend out of the sampling pipe 31, so that water is difficult to enter between the anti-fouling pipe 32 and the sampling pipe 31, and the deposition of dirt on the inner wall of the sampling pipe 31 can be better prevented. In sampling, one end of the anti-fouling pipe 32 extends into water, the other end is connected with the suction pump, the suction pump is operated in suction, a negative pressure is formed in the anti-fouling pipe 32, and water is sucked out to be sampled.
