[0002] In order to understand the specific situation of radioactive nuclides in seawater, it is necessary to take seawater samples and bring them back to the laboratory for component testing. Seawater sampling is an important means of studying marine science. It is of great significance to protecting the marine ecological environment and maintaining human health. It plays a role in studying the marine environment and monitoring marine pollution.

[0003] A seawater sampling device is disclosed in a Chinese utility model patent with application publication number CN110749474A, which belongs to the field of marine sampling technology. A connecting pipe and a partition are used to divide the internal space of a cavity into a first space, a second space and a third space. At the same time, a first through hole is used to connect the first space with the third space, and a second through hole is used to connect multiple third spaces. In this way, after the cavity is used to sample seawater, the seawater flows in the first space, the second space and the third space through the first through hole and the second through hole under the action of external force and waves. During the flow of seawater, the impact of the seawater can be relieved as soon as possible, and the seawater in the cavity can be stabilized and calmed as soon as possible, which is convenient for rapid measurement of seawater density and improves measurement efficiency.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the existing sampling devices are suitable for sampling seawater on the ocean surface. When seawater samples below the sea surface are needed, workers are required to dive into the seawater for sampling, which is a relatively cumbersome operation. Utility Model Content

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0020] Example 1: Please refer to Figure 1 - Figure 4 A marine radionuclide sampling device of the present embodiment comprises a shell 1 and a fixed rod 2, the top of the shell 1 is fixedly connected to the bottom of the fixed rod 2, two water inlets 4 are processed on both sides of the shell 1, baffles 3 are arranged on the inner sides of the two water inlets 4, a connecting plate 10 is fixedly connected to the inner side of the baffle 3, a rotating rod 8 is rotatably connected to the inside of the fixed rod 2, a hand wheel 7 is fixedly connected to the top of the rotating rod 8, a threaded rod 9 is fixedly connected to the bottom end of the rotating rod 8, one end of the threaded rod 9 is threadedly connected to the inside of the connecting plate 10, a third limiting ring 13 is fixedly connected to the bottom of the threaded rod 9, and a bottom plate 14 is hingedly connected to the bottom of the shell 1;

[0021] When sampling is required at a location below the sea surface, the staff puts the housing 1 into the seawater, and then turns the hand wheel 7, which drives the rotating rod 8 to rotate, which drives the threaded rod 9 to rotate, and the threaded rod 9 rotates to drive the connecting plate 10 to move downward, and the connecting plate 10 drives the two baffles 3 to move downward, thereby opening the water inlet 4 to allow seawater to enter the interior of the housing 1, and then turns the hand wheel 7 in the opposite direction to move the baffles 3 upward to close the water inlet 4, and finally lifts the housing 1 upward, and by opening the bottom plate 14, it is convenient to collect seawater for testing;

[0022] Further, one end of the rotating rod 8 is externally fixedly connected with a first limiting ring 11, and the other end of the rotating rod 8 is externally fixedly connected with a second limiting ring 12. The rotating rod 8 passes through the top of the housing 1, and the top of the second limiting ring 12 is rotatably connected to the top inner wall of the housing 1. Since the first limiting ring 11 and the second limiting ring 12 are fixedly connected at both ends of the rotating rod 8, when the rotating rod 8 rotates around the inside of the fixed rod 2, the first limiting ring 11 and the second limiting ring 12 limit the rotating rod 8 to move up and down inside the fixed rod 2;

When the connecting plate 10 drives the baffle 3 to move downward, the two ends of the baffle 3 will move downward along the inside of the chute 5. By providing the chute 5, the chute 5 will limit the movement of the baffle 3, so that when the threaded rod 9 rotates, the connecting plate 10 will drive the baffle 3 to move up and down;
