Bidirectional seal piston type abyss multicellular organism trapping and fidelity sampling device

Abstract

The invention relates to the technical filed of ultra-abyssal-sea multicellular organism fidelity sampling, and in particular to a bidirectional piston type abyss multicellular organism trapping and fidelity sampling device. The bidirectional piston type abyss multicellular organism trapping and fidelity sampling device comprises a bottom plate, wherein a sampling device, an underwater decelerator, a deep water motor, a control cabinet and an energy accumulator are uniformly distributed on the bottom plate; the sampling device comprises a pressure maintaining cylinder and a guiding cylinder which are connected through a flange; two ends of the pressure maintaining cylinder are opened; a sampling piston is arranged in the pressure maintaining cylinder, a cavity is formed in the sampling piston, a penetrated square opening is formed in the middle part of the sampling piston, and a sampling pipe is arranged in the cavity; two ends of the guiding cylinder are opened; the front end of the guiding cylinder is connected with the pressure maintaining cylinder through the flange, and the rear end of the guiding cylinder is connected with the connecting cylinder; the input end of the underwater decelerator is connected with the deep water motor; the energy accumulator is connected with the pressure maintaining cylinder through a capillary; and the control cabinet is connected with the underwater decelerator and the deep water motor through a watertight cable. Through the adoption of the bidirectional piston type abyss multicellular organism trapping and fidelity sampling device disclosed by the invention, pressure maintaining sampling can be completed, so that the obtained biological samples are guaranteed to be fundamentally kept in the in-situ pressure, and the survival rate oforganisms is greatly increased.

Description

technical field [0001] The invention relates to the technical field of fidelity sampling of ultra-deep-sea multicellular organisms, in particular to a two-way piston type trapping and fidelity sampling device for abyssal multicellular organisms. Background technique [0002] At present, the water depth of 1000m is usually used as the mark in the world, and sea areas with a water depth exceeding 1000m are called deep sea areas. The ocean area accounts for about 71% of the total area of ​​the earth, and most of this is the deep sea. Deep-sea strategic resources mainly include three categories: deep-sea oil and gas, deep-sea minerals, and deep-sea biological genetic resources. Deep-sea organisms have formed a unique biological structure and metabolic mechanism in a unique physical, chemical and ecological environment, which has extremely high economic value and great scientific research value. It is also of great scientific significance for humans to reveal the origin of life...
