Description

Technical Field

[0001] The utility model relates to the technical field of ocean water sampling, in particular to an ocean water sampler. Background Art

[0002] Water quality testing and analysis is one of the main contents of the national environmental protection supervision and inspection work. Especially in rivers and seas affected by sewage discharge, the testing and analysis of their water quality is even more important. There are also strict requirements for water quality sampling. Many tests require multiple water quality sampling points at different depths.

[0003] At present, in the prior art, for example, a Chinese patent with a publication number of CN212363798U discloses a fixed-depth sampler for monitoring marine water quality. The device arranges protective plates around the sampling bottle mounting seat, and arranges shock-absorbing plates and shock-absorbing compression springs on the inner wall of the protective plates. In the process of fixed-depth sampling of seawater, the sampling bottle can be effectively prevented from being damaged by the sea breeze or the collision with reefs. At the same time, by arranging a guide wheel, the sampling bottle can be effectively prevented from shaking, further ensuring that the sampling bottle is not damaged, thereby improving the monitoring efficiency. However, the device can only sample once each time. When it is necessary to sample marine water samples at different depths, the sampling device needs to be frequently recovered, resulting in low efficiency. In view of this, we propose a marine water sampler. Utility Model Content
