The device includes a hull, sampling analysis System and power system, etc., can collect samples conveniently and quickly, and its foldable hull structure is convenient for transportation and portability. "A remote control self-navigation water quality sampling and analysis device" published by CN101592649A is also an intelligent sampling device, which integrates a wireless communication module, a sampling analysis module and a navigation module, etc., and can perform multi-purpose water quality sampling and analysis. However, due to the limitations of the above-mentioned sampling equipment, it is greatly affected by the environment around the sampling point. In places where grass-shaped lakes and rivers are more complicated, they often cannot reach the sampling point normally due to reasons such as lush aquatic plants and shallow river depths. affect the collection of water samples.

Therefore, for the on-site water sample collection device, how to overcome the problems of being greatly affected by the sampling environment and low efficiency is still a difficult problem.
