[0002] With the continuous development of industrial technology and the continuous progress of society, people's living standards are getting higher and higher. However, the rapid development of industry has also brought about the destruction of the ecological environment, especially the pollution of water resources. Water is the source of life, and protecting water resources from pollution has become a top priority. At present, people's monitoring of water quality is mainly manual sampling of water quality. Manual sampling is labor-intensive and there is a certain risk of people falling into the water. Although some water quality sampling devices can automatically complete water quality sampling instead of manual work, the sampling device is too simple and has low stability. It can only complete one sampling each time, and it is impossible to sample water quality at different depths, and the work efficiency is low. Therefore, it is very necessary to design a water quality monitoring automatic sampling device with reasonable design, compact structure, convenient operation, energy saving, high degree of automation, reduced labor intensity, multi-point sampling, strong stability and reliability, high work efficiency, wide range of application, and strong practicality. It has broad market prospects and plays an important role and significance for the current water quality monitoring and water resource protection. Summary of the invention
