Background

The coastal wetland, the river wetland, the lake wetland and the artificial wetland are 5 types and 25 types in common in the Hainan island wetland, and the wetland types are very rich. The mangrove forest and coral reef wetland is the most important type of the south-of-the-sea island, and the south-of-the-sea island has the mangrove forest wetland with the largest area in China, which accounts for 82% of the area of the mangrove forest in China. Although the area of the whole-island constructed wetland is continuously enlarged, in recent years, due to economic development, cities are continuously expanded, and factors such as artificial cultivation destruction and water pollution influence are added, so that the area of the natural wetland is shrunk, and according to statistics, more than 35% of the natural wetland faces the threat of being reclaimed and reformed.

In the working process of wetland investigation and research, besides the arrangement of real-time water detection equipment, a wetland water sample needs to be periodically collected and then sent to a laboratory for further deep analysis. The wetland water sample collection equipment is the bucket formula sample thief at present, and it sinks the sampling bucket into the aquatic and gets the water sample, and this kind of operation mode causes the disturbance easily to the water, influences the sampling effect, and the operation is also relatively more inconvenient moreover. For this reason, it is necessary to develop a wetland water sample collection device capable of solving the above problems.
