Biological low-temperature storage device for deep-sea submersible

Abstract

The invention relates to a biont low-temperature preservation device for deep submergence vehicles. The biont low-temperature preservation device for the deep submergence vehicles comprises a pressure-resistant surrounding wall with a hollow cylinder structure, a bottom hatch cover is arranged at the bottom in the pressure-resistant surrounding wall through a supporting frame structure, a hydraulic cylinder driving the opening and closing of the bottom hatch cover is arranged between the middle position outside a hatch of the bottom hatch cover and the inner wall of the pressure-resistant surrounding wall, the upper part of the inner wall surface of the pressure-resistant surrounding wall is provided with a conical guide cylinder, the bottom surface of the conical guide cylinder is provided with a tray through pin shafts, the tray is downwards opened, a baffle block is arranged at one end of the bottom of the tray, the upper part of the tray is connected with the inner wall surface ofthe conical guide cylinder through a tension spring, the top surface of the pressure-resistant surrounding wall is provided with a top hatch cover through a hinge mechanism, and the top hatch cover isprovided with an electric sea suction valve. The outer wall surface of the pressure-resistant surrounding wall is sequentially provided with, from outside to inside, an outer-layer pressure-resistantshell, an intermediate-layer pressure-resistant shell and an inner-layer pressure-resistant shell which are all in a hollow spherical structure. The biont low-temperature preservation device for thedeep submergence vehicles is reliable in working.

Description

technical field [0001] The invention relates to the technical field of low-temperature preservation equipment for deep-sea organisms, in particular to a biological low-temperature preservation device for deep-sea submersibles. Background technique [0002] Deep-sea submersibles are one of the most important tools for ocean exploration and research. They have the functions of deep-sea prospecting, seabed high-precision topographic measurement, suspicious object detection and capture, and deep-sea biological investigation. In recent years, marine biologists have also used deep-sea diving Instruments, such as manned submersibles or cable-controlled robots (ROVs), conduct real-time observations of marine organisms, and conduct deep-sea sampling of valuable microorganisms and macrobiological samples through the manipulators mounted on the bow of the deep-sea submersible, and through fixed The sampling baskets on the tray are collected and stored for laboratory observation, cultiv...

Problems solved by technology

[0003] However, in the prior art, the biological samples collected by the deep-sea submersible are stored in the sampling basket. With the recovery of the ROV, the biological samples are also lifted from the deep sea to the surface mother ship. Because the process of ROV recovery from the deep sea to the surface , the temperature of the external seawater where the biological samples are located is also gradually rising. Therefore, the biological characteristics of the biological samples have changed during the transfer process due to the lack of in-situ low-temperature preservation of the samples in this type of rough deep-sea sampling, and lost The in-situ characteristics of organisms even lose the value of laboratory observation, cultivation and research
