The invention discloses a ship-mounted automatic small-amount seawater sampling device. The device comprises a pumping device, a horizontal movement device, and a vertical movement device, wherein thepumping device comprises a syringe assembly and a gripper screw-nut mechanism; the syringe assembly serves as a sampling pipe, and is driven by the gripper screw-nut mechanism to collect seawater andsend samples to a detection device; the horizontal movement device comprises a horizontal movement steering engine and a horizontal movement screw-nut mechanism, and the horizontal movement steeringengine controls a gripper bearing pedestal to move horizontally through the horizontal movement screw-nut mechanism; the pumping device is fixed on the gripper bearing pedestal; the vertical movementdevice comprises a driving mechanism and vertical guiding mechanisms; and a stepping motor in the driving mechanism controls a steel wire rope, which passes through the vertical guiding mechanisms, toextend and retract, so as to drive the horizontal movement device and the pumping device at the other end of the steel wire rope to carry out sampling on seawater at different depths. The sampling device provided by the invention has the advantages that the sampling stability is high; and within a certain depth range, the seawater at the different depths can be sampled, and repeated sampling is achieved.
Description
technical field [0001] The invention relates to the technical field of detection of hazardous chemicals in seawater, in particular to a small-volume automatic sampling device for seawater mounted on a hull. Background technique [0002] With the continuous development of ocean transportation, the demand for the transportation of dangerous goods such as chemical raw materials is increasing, and leakage accidents during the transportation of dangerous chemicals are common. For example, the East China Sea oil tanker oil spill accident that occurred on January 6, 2018 caused immeasurable damage to the surrounding sea environment. In the leakage accident of hazardous chemicals at sea, the hazardous chemicals generally float on the water surface. During the detection process, the fast-response and high-sensitivity immunocolloidal gold reagent stick detection technology can be used to obtain the hazardous chemicals at the accident site in a timely and accurate manner Leakage situa...
