Deep-sea sediment sampler loaded on underwater vehicle

The invention discloses a deep-sea sediment sampler loaded on an underwater vehicle. The sampler comprises a sampling device and a storage device, wherein the sampling device mainly comprises a sampling pipe component and a length adjusting component, and a resistance adjusting component is arranged between the sampling pipe component and the length adjusting component; the sampling pipe device is movably inserted into the storage device. According to the deep-sea sediment sampler, the structure is simple, the operation reliability is high, the loading condition is flexible, and through the resistance adjustable check valve structure, high-quality deep-sea sediment samples and water samples are obtained from different seafloor sediments; PC materials with high transparency are adopted, so that an operator can intuitively primarily estimate the samples; due to the adoption of section assembling mode, sediment samples can be extracted and stored without disturbance; the deep-sea sediment sampler is suitable for loading operations of underwater tethered submersibles, manned submersibles and the like.
