Seawater sampling device

Abstract

The invention discloses a seawater sampling device. The seawater sampling device comprises a cavity, and a handle arranged on the cavity, wherein a connection pipe is vertically arranged in the cavityto divide the internal space of the cavity into a first space and a second space; a plurality of partition plates are divergently and uniformly arranged around the central line of the connection pipein the second space, so as to divide the second space into a plurality of third spaces; a plurality of first through holes, through which the third spaces can communicate with the first space, are formed in the connection pipe; at least one second through hole, through which the third spaces can communicate with one another, is formed in each of the partition plates; and an opening is reserved atthe top of the connection pipe and used for the insertion of a measurement piece. The seawater sampling device disclosed by the invention has the advantages that seawater in a container can be quickly calmed down and stabilized to facilitate timely seawater measurement, so that the sampling and measurement efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a seawater sampling device. Background technique [0002] During the ship's navigation, whether the ship's floating state meets the test conditions is related to the safety of the ship's navigation and the success of the test. The seawater density in the actual sea area where the ship is located is an important factor determining the ship's floating state. When measuring the density of seawater in a certain sea area, the staff generally tie a rope to the handle of a container with a height of 380 mm and a volume of 18 liters with an opening on one side, throw the container into the ship's side to fill it with sea water and lift it up. Put it on the deck, put the seawater density meter into the water after the free liquid surface of seawater in the container is calm, and observe the reading of the seawater density meter suspended in the water stably, so as to determine the density o...

Problems solved by technology

During this process, due to the joint action of various external forces such as wind and waves at sea, the seawater in the container will have fluctuations and ripples on the surface of the seawater in the container. It takes 5 minutes to calm down gradually, so that the measurement The seawater density takes a long time and the measurement efficiency is low; on the other hand, even if the seawater in the container is calm to a certain extent and the density meter is put in, due to the water wave phenomenon in the container, when the density meter is put in the container, the density meter will be in the container. Under the action of external forces such as its own gravity and water waves, there will be a phenomenon of floating up and down and circular rotation for 3-5 minutes, which prolongs the observation time of the density meter stably suspended in the container and reduces the density observation efficiency
