Benthos preservation sampling device and benthos preservation sampling method for deep-sea lander

Abstract

The invention discloses a benthos preservation sampling device for a deep-sea lander, which comprises a pressure maintaining cylinder, wherein the outer wall of the pressure maintaining cylinder is provided with a pressure compensating device, a bait cylinder, a semiconductor refrigerating assembly and a circuit cylinder; the pressure compensating device communicates with the pressure maintainingcylinder, the bait cylinder communicates with an inner cavity of the pressure maintaining cylinder through a switching valve; an inlet sealing mechanism is arranged at an inlet of the pressure maintaining cylinder; a beard-inverting opening mechanism is arranged in the inner cavity of the pressure maintaining cylinder; an outlet sealing mechanism and a gear mechanism are arranged at an outlet of the pressure maintaining cylinder; the inner wall of the pressure maintaining cylinder is provided with a pressure sensor and a temperature sensor; a power supply and a controller are arranged in the circuit cylinder, and the controller is connected with the semiconductor refrigerating assembly, the pressure sensor and the temperature sensor. The benthos preservation sampling device of the invention can realize trapping and heat-preservation pressure-maintaining culture of benthos and can effectively ensure the in-situ vital signs of the benthos; and meanwhile, the benthos preservation samplingdevice of the invention can be butted with a culture kettle, and can be used for transferring the benthos into the culture kettle in a preservation way.

Description

technical field [0001] The invention relates to a seabed biological sampling device, in particular to a seabed biological fidelity sampling device and a fidelity sampling method for a deep-sea lander. Background technique [0002] There are a large number of biological communities on the seabed, and scientific research on these seabed organisms is an important means for human beings to understand and study the evolution of marine life and the seabed environment. Traditional means of seabed biological sampling are trawling nets or non-pressure-holding and heat-preserving traps. Because these traditional seabed biological sampling devices cannot maintain the in-situ pressure and temperature of the deep seabed, the collected organisms have been lost in the process of returning to the surface mother ship from the seabed. This will have a great impact on the precise research on the living conditions of organisms in the seabed area and the seabed environment. The deep-sea lander ...
