Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figures 1-5 As shown, this utility model includes an electric cylinder 1, a syringe 2, a two-way valve 5, a multi-way valve, a water storage bag 4, and a fixing frame. In this embodiment, the multi-way valve is a ten-way valve 7, which has one common end and ten ports.

[0030] The electric cylinder 1, syringe 2, two-way valve 5, and multi-way valve are respectively mounted on the fixed frame. The telescopic rod of the electric cylinder 1 is connected to the syringe plunger 3. The interface of the syringe 2 is connected to the common end 711 of the ten-way valve 7. One interface of the ten-way valve 7 is connected to the external water area. Each of the remaining interfaces of the ten-way valve 7 is connected to a two-way valve 5. Each two-way valve 5 is connected to a water storage bag 4. A shut-off valve is installed at the port of the water storage bag 4.

[0031] like Figure 1 , Figure 3 As shown, the fixing frame in this embodiment includes a base plate 11, a first fixing plate 13, a second fixing plate 14, and side rods 12. Four side rods 12 are provided on the base plate 11. The first fixing plate 13 and the second fixing plate 14 are provided at the top of the side rods 12, and the first fixing plate 13 and the second fixing plate 14 are connected. The bottom end of the side rod 12 is fixed to the base plate 11, and the top end of the side rod 12 is connected to the first fixing plate 13 or the second fixing plate 14. An electric cylinder 1 is installed on the base plate 11, and a syringe 2 is installed on the first fixing plate 13. The telescopic rod of the electric cylinder 1 is connected to the syringe push rod 3, and the syringe push rod 3 is pushed and pulled by the power of the electric cylinder 1.

[0032] The ten-way valve 7 is mounted on the second fixed plate 14. For example... Figure 5 As shown, a common end 711 is provided in the middle of the top of the ten-way valve 7, and the interface of the syringe 2 is connected to the common end 711 of the ten-way valve 7. In addition to the common end 711 in the middle, the ten-way valve 7 has ten interfaces around it, namely the first interface 701, the second interface 702, the third interface 703, the fourth interface 704, the fifth interface 705, the sixth interface 706, the seventh interface 707, the eighth interface 708, the ninth interface 709 and the tenth interface 710.

[0033] The underwater in-situ high-fidelity sampler in this embodiment also includes a guide pipe 8 and a water sampling probe connected to an external water body. One end of the guide pipe 8 is connected to one of the ports of a ten-way valve 7, and the other end of the guide pipe 8 is connected to the water sampling probe, which is used to connect to the external seawater for water sampling. In this embodiment, the fifth port 705 of the ten-way valve 7 is selected to connect to the seawater through the guide pipe 8 and the water sampling probe.

[0034] This embodiment also includes nine first connecting pipes 9. Except for the fifth interface 705, the other first interfaces 701, second interface 702, third interface 703, fourth interface 704, sixth interface 706, seventh interface 707, eighth interface 708, ninth interface 709, and tenth interface 710 are each connected to one first connecting pipe 9. Each first connecting pipe 9 is connected to a two-way valve 5. The number of the two-way valve 5 corresponds to the number of the ten-way valve 7 interface it is connected to. For example, the ninth interface 709 of the ten-way valve 7 is connected to the ninth two-way valve 509 through the first connecting pipe 9.

[0035] This embodiment also includes nine second connecting pipes 10. Each two-way valve 5 is connected to one second connecting pipe 10, and each second connecting pipe 10 is connected to a water storage bag 4 via a shut-off valve. The number of the water storage bag 4 also corresponds to the interface number of the ten-way valve 7. For example, the ninth interface 709 of the ten-way valve 7 is connected to the ninth two-way valve 509 via the first connecting pipe 9, and the ninth two-way valve 509 is connected to the ninth water storage bag 409 via the second connecting pipe 10.

[0036] Each water bag 4 is equipped with a shut-off valve with a manual knob, located at the connection between the water bag 4 and the second connecting pipe 10; both ends of the second connecting pipe 10 between the two-way valve 5 and the shut-off valve are also equipped with detachable quick connectors. When the water bag 4 needs to be removed individually, closing the shut-off valve can prevent the samples collected inside the water bag 4 from spilling.

[0037] This embodiment also includes a two-way valve mounting bracket 6 disposed on the second fixed plate 14, wherein the two-way valves 5 are arranged in a ring on the two-way valve mounting bracket 6.

[0038] This embodiment also includes a power supply, which is electrically connected to the electric cylinder 1.

[0039] The control of the two-way valve 5 and the ten-way valve 7 of this utility model is existing technology and can be achieved through a controller.

[0040] The working principle of this utility model is as follows:

[0041] The electric cylinder 1 drives the syringe plunger 3 to push and pull, and connects to the external seawater through one interface of the multi-way valve to extract seawater; the opening and closing of the two-way valve 5 controls the individual opening and closing of each water storage bag 4, ensuring that water sampling at different points can be carried out independently and without interference, avoiding cross-contamination between different points.

[0042] The embodiments of this utility model are only used to illustrate the technical solutions of this utility model and are not intended to limit it. For those skilled in the art, it will be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
