Abstract

The invention relates to a deep-sea organism capturing and culturing technology, and aims to provide a deep-sea multicellular organism pressure-maintaining capturing and long-term culture device. The two ends of a pressure maintaining cavity of the device are open, and movable end covers are arranged on the inner side for sealing; a spring sleeve mechanism is arranged in the pressure maintaining cavity in parallel, an inner sleeve and an outer sleeve are in coaxial interference fit, and the two ends of a spring are fixed to a movable end cover. The outer side of the movable end cover is connected with a damping release mechanism; the pressure maintaining cavity is further connected with an energy accumulator system, a fresh seawater conveying system and a food feeding system. By adopting a sealed triggering structure, the structure of the biological pressure-maintaining sampling equipment is simplified, the weight is reduced, and the operation is simple and convenient. The two ends of the pressure maintaining cabin are sealed by the movable end covers, and the movable end covers are powered by the spring sleeves, so that the design of a motor, an oil cylinder and a transmission structure which are possibly added is omitted, the overall structure is simplified, and the cost is saved. The matched culture system can provide seawater circulation renewal, oxygen supply and physical nutrition supply for multicellular organisms.

Description

technical field [0001] The invention relates to deep-sea organism capture and culture technology, in particular to a deep-sea multicellular organism pressure-holding capture and long-term culture device. Background technique [0002] The deep sea biosphere is one of the largest but least developed biological habitats on earth, which is mainly limited by the lack of sampling and cultivation methods. Under deep-sea conditions, biological pressure sampling, pressure transfer after recovery, and long-term culture are important technical means for studying deep-sea organisms. [0003] In terms of pressure-holding sampling techniques for deep-sea multicellular organisms (as opposed to microorganisms), they are mainly divided into two categories according to their deployment methods. One is lander-based sampling technology, which deploys equipment on a lander with buoyant materials and deploys counterweights on the lander. After arriving at the bottom of the sea, the driving devi...
