[0002] Water sampling refers to the process of collecting samples from polluted water bodies according to certain procedures and methods in order to evaluate and monitor the environmental quality of water bodies. These samples are usually sent to laboratories for analysis to obtain basic data on the pollution status of water bodies.

[0003] Announcement No. CN220322836U discloses a sampling device that can take samples at different depths. The sampling device is equipped with a filtering and pumping structure, which can determine the depth of the suction pipe entering the water according to the position of the float, thereby obtaining water quality samples at different depths, thereby improving the functionality of the sampling device.

Pressing the sliding rod 431 causes the limiting column 434 to slide downward, slide out of the deep groove of the limiting groove 435, and enter the rotating groove 436. After a 90° rotation rebound is achieved through the torsion spring 433, it is redirected to slide back into the shallow groove of the limiting groove 435.
