Underwater vehicle carrying type sediment fidelity sampler

Abstract

The invention provides an underwater vehicle carrying type sediment fidelity sampler, and relates to the field of deep-sea sediment sampling. The underwater vehicle carrying type sediment fidelity sampler comprises a deposition box body, a gear ring is arranged in the deposition box body, four first gears are connected to the interior of the gear ring in an engaged mode, rotating rods are fixedly connected to the tops of the four first gears, first bevel gears are fixedly connected to the outer sides of the four rotating rods, and the first bevel gears are fixedly connected to the outer sides of the first bevel gears. And the bottoms of the four first bevel gears are in engaged connection with second bevel gears. According to the underwater vehicle carrying type sediment fidelity sampler, a second bevel gear rotates to drive a rotating shaft to rotate, the rotating shaft rotates to drive an eccentric wheel to rotate, according to the same working principle, a second fidelity sampler body is driven to move upwards so as to rapidly sample, the structure is beneficial to sampling of different point positions, the structure is simple, and operation is convenient. The operation is convenient, and meanwhile, through double-layer sealing, the sealing performance of the fidelity sampler body is higher.

Description

technical field [0001] The invention relates to a fidelity sampler, in particular to a sediment fidelity sampler mounted on an underwater carrier, which belongs to the technical field of deep-sea sediment sampling. Background technique [0002] Deep-sea sediments are seabed materials formed by marine sedimentation, and contain a large amount of geological and biological information. The types and distribution of deep-sea sediments, transportation and dynamic processes, geotechnical characteristics, and microbial communities are investigated and researched. Resource mining in the later stage is of great significance. The traditional sediment acquisition is mainly through the release of the sampling device by the ship's geological winch. After bottoming under the action of gravity, it is recovered to the sea surface. The whole process cannot be monitored and the structure is cumbersome. By carrying a deep-sea vehicle for seafloor sampling, scientists can use high-definition ca...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of sediment fidelity sampler mounted on the underwater vehicle in order to solve the above problems, to solve the problem that in the prior art, when sampling the sampling point, it is generally impossible to dive once and then conduct multiple samplings. Point sampling, when sampling at multiple points at the same time, the sealing of the sampler is not good, and after the sampler returns to the laboratory, it is inconvenient to take out the included sampler, and the structure is relatively complicated
