Closed type seawater sampling system

Abstract

The invention discloses a closed type seawater sampling system, which aims to provide a seawater sampling system which not only is convenient to operate and low in labor intensity in the water sampling system, but also can meet the actual requirement of high-density sampling. The closed type seawater sampling system comprises a rack, a water pump, a water pumping pipeline, a connecting pipeline, a water exhaust pipeline, a vertical water storage cylinder, a sampling inlet and outlet, a first piston body and a lifting actuating device, wherein the vertical water storage cylinder is fixedly arranged on the rack; the sampling inlet and outlet is formed in the lower end of the vertical water storage cylinder; the first piston rod is arranged right below the sampling inlet and outlet; the lifting actuating device is arranged on the rack and is used for lifting the first piston rod; the first piston rod can move upward into the sampling inlet and outlet and seal the sampling inlet and outlet; the lower part of the side surface of the vertical water storage cylinder is provided with a water inlet; the upper end of the vertical water storage cylinder is provided with a water outlet; one end of the water pumping pipeline is connected with an inlet of the water pump; one end of the connecting pipeline is connected with a water outlet of the water pump, and the other end of the connecting pipeline is connected with a water inlet of the vertical water storage cylinder; one end of the water exhaust pipeline is connected with a water outlet of the vertical water storage cylinder.

Description

technical field [0001] The invention relates to a water collection device, in particular to a closed seawater sampling system. Background technique [0002] The water body in the water area is affected by factors such as material, water flow, and temperature, and there will be a stratification effect. The hydrological, physical, chemical, and biological information of different water layers is different. Collecting and analyzing the differences in water bodies at different layers is a key step in environmental science and marine science. It is widely used in practical fields such as water ecological environment assessment and pollution accident investigation. [0003] The traditional water collector usually hangs the water collector on the traction rope; then, the operator lowers the water collector to the water layer at a specific depth through the rope, and takes water samples at the water layer at the depth through the water collector. Collect; then, the operator lifts t...

Problems solved by technology

Although this type of pump suction water collection device reduces the labor intensity, because the water sample sucked up by the water pump will inevitably come into contact with the outside air and be disturbed during the water sample collection process, thus affecting the analysis of the collected water sample The authenticity and validity of the water environment represented by the results
