AI Technical Summary
In existing marine environmental monitoring, water sampling devices cannot achieve fixed-depth water sampling and have complex structures, resulting in a large consumption of manpower, material resources, and financial resources.
Design a nearshore unmanned water sampling device that includes a drone, a lifting mechanism, and a water sampler. The lifting mechanism controls the water sampler to reach a designated depth for fixed-depth water sampling, and a one-way valve is used to allow seawater to enter the water collection chamber. The structure is simple and easy to operate.
It has achieved fixed-depth water sampling, reduced the consumption of manpower, material resources and financial resources, improved sampling efficiency, and has all-weather sampling capability.

Abstract
Claims
1. An offshore unmanned water-sampling device, characterized by: The device includes a drone, a lifting mechanism, and a water sampler. The water sampler includes a water collection shell with a water collection chamber inside. The bottom of the water collection chamber has a water inlet with a one-way valve. A piston rod is slidably mounted inside the water collection chamber, with its top extending upwards out of the chamber and a piston at its bottom. Two lifting mechanisms are provided, both mounted on the drone. One lifting mechanism is connected to the water collection shell, and the other is connected to the top of the piston rod.
2. The offshore water-sampling unmanned device according to claim 1, characterized in that: The bottom of the water collection chamber is also provided with a drain outlet, and a sealing plug is provided on the drain outlet to seal it.
3. The offshore water-sampling unmanned device according to claim 2, characterized in that: The drain outlet is provided in multiple ways, and each drain outlet is provided with a sealing plug.
4. The offshore water-sampling unmanned device of claim 1, wherein: The piston is also fitted with a sealing ring on its outer edge to achieve a seal with the inner wall of the water collection chamber.
5. The offshore water-sampling unmanned device of claim 1, wherein: A connecting bracket is also provided on one side of the water intake shell, one of the lifting mechanisms is connected to the top of the connecting bracket, and the other lifting mechanism is connected to the top of the piston rod.
6. The offshore water-sampling unmanned device according to claim 5, characterized in that: Both the top of the connecting bracket and the top of the piston rod are provided with lifting rings for hanging on the two lifting mechanisms respectively.
7. The offshore water-sampling unmanned device of claim 1, wherein: The lifting mechanism is an electric hoist.
8. The offshore water-sampling unmanned device of claim 1, wherein: The one-way valve includes a valve body, a valve core, and a spring. The valve body has a first channel and a second channel connected sequentially from bottom to top. The diameter of the second channel is larger than the diameter of the first channel. The first channel and the second channel are connected by a first conical surface with a larger upper opening and a smaller lower opening. The top of the second channel is connected to the water inlet. The valve core is disposed in the second channel. A spring is disposed between the top of the valve core and the water inlet. The diameter of the valve core is smaller than the diameter of the second channel. The bottom of the valve core has a second conical surface that can fit against the first conical surface to close the first channel.
9. The offshore water-sampling unmanned device of claim 1, wherein: It also includes an infrared night vision system, which is mounted on the drone.
10. The offshore water-sampling unmanned device according to claim 9, characterized in that: It also includes a heating pad, which is attached to the water sampler.
