[0002] Plankton refers to a group of organisms that passively float in the water column under the influence of water flow. They are the basis of the aquatic food chain and occupy an important position in aquatic ecosystems. They are mainly composed of phytoplankton and zooplankton.

[0003] Existing plankton sampling devices have a simple structure and can only sample a single depth of water at a time, making it difficult to sample multiple depths of water simultaneously. This results in low sampling efficiency and inconvenience for staff to use. Summary of the Invention

By pulling the piston, plankton from different water layers can be extracted at the same time and stored in the sampling tubes, thereby improving sampling efficiency and making it convenient for staff to use.

[0008] Preferably, the diameters of the connecting bolts and connecting screw holes are respectively adapted to the diameters of threaded hole one, threaded hole two, mounting bolt one, and mounting bolt two.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] Referring to Figures 1-8, a multi-layer plankton collector includes a sampling cylinder 1. A sliding rod 4 is slidably connected inside the sampling cylinder 1. A pull ring 5 is fixedly connected to the rear end of the sliding rod 4. A piston 6 is fixedly connected to the front side of the sliding rod 4. The diameter of the piston 6 is the same as the inner wall diameter of the sampling cylinder 1, and the piston 6 fits tightly against the inner wall of the sampling cylinder 1. A connecting screw hole 3 is fixedly connected to the bottom of the sampling cylinder 1. A mounting bolt 11 is threaded inside the connecting screw hole 3. A connecting rod 10 is fixedly connected to the bottom of the mounting bolt 11. A threaded hole 12 is fixedly opened at the bottom of the connecting rod 10. A counterweight 13 is provided at the bottom of the sampling cylinder 1, and a mounting bolt 14 is fixedly connected to the top of the counterweight 13. The top of the sampling cylinder 1 is fixedly connected to a connecting bolt 2. The diameters of the connecting bolt 2 and the connecting screw hole 3 are respectively matched with the diameters of the threaded hole 8, the threaded hole 12, the mounting bolt 11, and the mounting bolt 14. The top surface of the connecting bolt 2 is threadedly connected to a handle 7. The bottom of the handle 7 has a threaded hole 8. The rear end of the handle 7 is fixedly connected to an electric push rod 9. The pull ring 5 is internally slidably connected to a pull rod 15. The top of the pull rod 15 is fixedly connected to a push plate 17. The bottom of the pull rod 15 has a threaded hole 16. The threaded hole 16 has a mounting bolt 18 internally connected to a mounting bolt 19. The bottom of the mounting bolt is fixedly connected to an extension rod 19. The bottom of the extension rod 19 has a threaded hole 20.

[0028] Working principle: When in use, the operator simply holds the handle 7 and inserts the device into the designated water area. At this time, the three vertically distributed sampling tubes 1 can extend to three different water depths. The counterweight 13 increases the weight of the device, making it easier for the operator to extend the device into the water. The operator then activates the electric push rod 9 on the handle 7. The extension end of the electric push rod 9 extends backward, thereby contacting the push plate 17 and pushing the push plate 17 backward. This movement in turn drives the pull rod 15 and the extension rod 19 backward. Since the pull rod 15 and the extension rod 19 are both fitted inside the pull ring 5, they also drive the sliding rod 4 backward through the pull ring 5. When the sliding rod 4 moves, it pulls the piston 6. By pulling the piston 6, plankton from different water depths can be extracted simultaneously through the three sampling tubes 1 and stored in the sampling tubes 1, thereby improving sampling efficiency and making it convenient for operators to use.

[0029] Compared with related technologies, the multi-layer plankton collector provided by this utility model has the following beneficial effects: by setting up sampling tubes 1, pistons 6 and other components for use, the number of sampling tubes 1 is three, and the three sampling tubes 1 are vertically distributed, so that they can extend to three different water depths. By pulling the piston 6, plankton from different water layers can be extracted at the same time and stored in the sampling tubes 1, thereby improving sampling efficiency and making it convenient for staff to use. Example

[0030] Referring to Figures 1-9, the sampling cylinder 1 has a sliding rod 4 internally connected to it. A pull ring 5 is fixedly connected to the rear end of the sliding rod 4. A piston 6 is fixedly connected to the front side of the sliding rod 4. A connecting screw hole 3 is fixedly connected to the bottom of the sampling cylinder 1. A mounting bolt 11 is threaded inside the connecting screw hole 3. A connecting rod 10 is fixedly connected to the bottom of the mounting bolt 11. A threaded hole 12 is fixedly opened at the bottom of the connecting rod 10. A counterweight 13 is provided at the bottom of the sampling cylinder 1. A mounting bolt 14 is fixedly connected to the top of the counterweight 13. A connecting bolt 2 is fixedly connected to the top of the sampling cylinder 1. A handle 7 is threadedly connected to the top surface of the connecting bolt 2. A pull rod 15 is internally connected to the pull ring 5. A push plate 17 is fixedly connected to the top of the pull rod 15. A threaded hole 16 is opened at the bottom of the pull rod 15. A mounting bolt 18 is threaded inside the threaded hole 16. An extension rod 19 is fixedly connected to the bottom of the mounting bolt. A threaded hole is opened at the bottom of the extension rod 19.

[0031] Working principle: During use, the operator can install the connecting rod 10 onto the sampling cylinder 1 by threading it into the connecting screw hole 3 at the bottom of the sampling cylinder 1. Then, the operator can thread a new sampling cylinder 1 onto the threaded hole 12 at the bottom of the connecting rod 10. This allows the operator to increase or decrease the number of sampling cylinders 1 according to the actual usage. Increasing the number of connecting rods 10 can extend the distance between the sampling cylinders 1, thus adapting to different depths. The pull rod 15 can also be threaded into the extension rod 19 to extend its length, thus matching the number of sampling cylinders 1. The operation is simple and convenient for operators to use.

[0032] Compared with related technologies, the multi-layer plankton collector provided by this utility model has the following advantages: by setting up sampling tubes 1 and connecting rods 10, the operator can connect multiple connecting rods 10 and multiple sampling tubes 1 with each other through threads, so as to increase or decrease the number of sampling tubes 1 according to the actual use. The distance between sampling tubes 1 can also be adjusted by connecting rods 10 to adapt to different depths. The operation is simple and convenient for operators to use.
