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...
