Description

technical field The invention belongs to the technical field of water conservancy engineering, and in particular relates to a deep water sample sampling device for water conservancy reservoirs. Background technique Reservoirs are generally interpreted as "hydraulic engineering structures that hold back flood water and regulate water flow, and can be used for irrigation, power generation, flood control and fish farming." It refers to artificial lakes formed by building dams at the narrow mouths of ravines or rivers . After the reservoir is completed, it can play the roles of flood control, water storage for irrigation, water supply, power generation, and fish farming. Some reservoirs are the main source of urban water supply. Therefore, the assessment and monitoring of the water quality in the reservoir through the collection of reservoir water samples is an important part of the scientific research of water environment and the protection and management of water environment....
