Abstract

The invention relates to a deep-sea organism pressure-maintaining sampling device, and aims to provide a push rod sealed macro organism trapping pressure-maintaining sampler based on a deep-sea submersible. The sampler comprises a hollow pressure maintaining cylinder body, open holes are formed in the two opposite side walls of the pressure maintaining barrel respectively, and a cylindrical sampling push rod capable of moving in the axial direction is arranged in the two open holes in a penetrating mode. Limiting end covers are arranged at the two ends of the sampling push rod respectively, a long groove hole is formed in the position close to the bottom limiting end cover, and a handle is installed on the top limiting end cover. A locking device is arranged at at least one opening of the pressure maintaining cylinder, a locking part is arranged on the limiting end cover on the same side as the locking device, the locking device and the limiting end cover are assembled to limit the axial displacement of the sampling push rod, and the sampling push rod is used for blocking the two openings of the pressure maintaining cylinder to seal the inner cavity of the pressure maintaining cylinder. The sealing mechanism is light in weight, simple to operate and capable of accurately sampling at fixed points; the operation difficulty of a mechanical arm is reduced, and non-sampling-depth organisms can be prevented from entering the sampler in the lowering process.

Description

technical field [0001] The invention relates to a deep-sea biological pressure maintaining sampling device, in particular to a push rod sealed macro biological trapping pressure maintaining sampler based on the operation of a deep-sea submersible manipulator. Background technology [0002] At present, most of the sampling methods for obtaining abyssal macro biological samples in deep-sea environment are non fidelity. This method will lead to the serious damage of most organisms after being recovered to the sea surface due to the changes of temperature and pressure environment, so it is impossible to carry out the next biological living body observation and research. [0003] There are also a few pressure maintaining samplers that can obtain abyssal macro biological samples under in-situ pressure, but they basically use the large-diameter ball valve or butterfly valve at the sampling port to form a seal. This leads to heavy equipment and complex operation, and its opening layout i...
