Abstract

Provided is a mechanical handheld hermetic sampler for marine sediment. The sampler comprises sampling assembly and a pressure maintaining assembly. The sampling assembly includes a sampling tube, a handle and an end cap. The sampling tube is fixed at a lower end surface of the end cap while the handle is fixed at an upper end surface of the end cap. The handheld robotic sampler for marine sediment with hermetic sampling is simple and compact in structure, small in size, light in weight, easy to manipulate and manufacture, highly reliable, and particularly suitable for robotic sampler hand control of underwater operating equipment such as a manned submersible, an unmanned submersible and Remotely Operated Vehicle.
