Embodiment Construction

[0032] The following examples can make those skilled in the technical field understand the present invention more comprehensively, but do not limit the present invention in any way.

[0033] Such as figure 1 and figure 2 As shown, a trapping and fidelity sampler for subsea abyss macro organisms includes a base plate 1, a handle 2, a pressure-holding cylinder 3, a guide cylinder 4, an underwater oil-filled reducer 5, a deep-water oil-filled motor 6, and an electronic cabin 7. Accumulator 8.

[0034] The pressure maintaining cylinder 3 is placed in the support seat, and is fixed together with the support seat through hoops, and the lower part of the support seat is fixed on the base plate 1 by bolts. When working, the bottom plate is fixed on the lander by hoops. Both ends of the pressure-holding cylinder 3 are open, and the rear end is flange-connected with the guide cylinder 4 . There is a sampling piston 18 inside the pressure-holding cylinder 3, and a cavity is arranged...

Abstract

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. Including the bottom plate, the sampling device, underwater reducer, deep-water motor, control cabin, and accumulator are evenly arranged on the bottom plate; the sampling device includes a pressure-holding cylinder and a guide cylinder connected by flanges. There is a sampling piston; there is a cavity inside the sampling piston, a through square opening is opened in the middle, and a sampling tube is arranged in the cavity; both ends of the guide cylinder are open, the front end is connected to the pressure-holding cylinder through a flange, and the rear end is connected to the connecting cylinder The input end of the underwater reducer is connected to the deep-water motor, the accumulator is connected to the pressure-holding cylinder through a capillary tube, and the control cabin is connected to the underwater reducer and the deep-water motor respectively through watertight cables. The device of the invention can complete pressure-holding sampling, ensure that the obtained biological samples are basically maintained at the in-situ pressure, and greatly improve the survival rate of organisms.

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...
