[0002] The marine environment refers to the total water area of ​​the vast and continuous seas and oceans on the earth, including seawater, substances dissolved and suspended in seawater, seabed sediments and marine life. It is the cradle of life and a treasure trove of human resources. As the scale of human development of marine resources continues to expand, the marine environment has been affected and polluted by human activities. In order to protect the marine environment, regular testing is required. One of the marine environment tests is seawater testing, which requires sampling of seawater and testing with testing instruments.

[0003] Announcement No. (CN218916936U) discloses a marine environment detection filtration sampling device. After the seawater is filtered through the filter, it is introduced into the guide cover, and then into the sampling tube through the guide cover. When the seawater in the sampling tube accumulates to a certain amount, it is introduced into the sampling tube through the guide tube. When sampling is actually performed, it is necessary to sample seawater at different depths. The above device cannot sample seawater at different depths at the same time, which will affect the sampling efficiency and needs to be improved. Utility Model Content
