Background

In the process of scientific research and investigation of wild small-sized wetlands such as rivers, streams, ponds, reservoirs and the like, water sample extraction is an essential working link. However, in the actual water taking process, due to the fact that large muddy and messy stone areas exist in wetland areas such as riverway sides and reservoir sides, scientific research personnel take a sample bottle to move on the muddy and messy stone areas for sampling, and great potential safety hazards exist.

Meanwhile, the water depth on the shore is usually shallow, and the obtained water sample cannot represent the whole body, so that the water samples are required to be sampled in water areas close to the shore and different in distance and depth.
