[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides.

[0003] The patent name is "CN215811802U", which is published as: A deep water sampling device for water quality monitoring. The device in the public document can sample water, but after each sampling of water, the staff needs to remove the device from the water body, so as to take the sampled water out of the device, and then put the device into the water body at other depths for sampling. This operation method makes it impossible for the device in the public document to sample water bodies of different depths at one time. The operation steps are time-consuming and labor-intensive, which increases the workload of the staff and reduces the efficiency of water sampling. Based on this, the utility model designs a deep water sampling device for water quality monitoring to solve the above problems. Utility Model Content
