Suction type deep sea seabed organism collection and in-situ maintaining system and use method thereof

Abstract

The invention discloses a suction type deep sea seabed organism collection and in-situ maintaining system and a use method thereof. The system comprises a pressure maintaining tube, a pressure compensating device, a barbed opening mechanism, semiconductor refrigerating assemblies, a circuit tube and a collecting tube, wherein a sealing mechanism I and a sealing mechanism II are separately arrangedat two ends of the pressure maintaining tube; the barbed opening mechanism is arranged in an inner cavity of the pressure maintaining tube; the pressure compensating device communicates with the pressure maintaining tube through a high-pressure pipe; the semiconductor refrigerating assemblies are arranged on the outer walls of the pressure maintaining tube; a power supply and a controller are arranged in the circuit tube; the semiconductor refrigerating assemblies are connected with the controller; a pressure sensor and a temperature sensor are arranged on the inner wall of the pressure maintaining tube, and are separately connected with the controller; and the collecting tube communicates with a valve hole of the sealing mechanism II through a pipeline. The structure is simple and compact; the operation is simple and convenient; the trapping and heat-preservation pressure-maintaining culture on deep sea seabed organisms can be realized; and the in-situ life characteristics of the deep sea seabed organisms can be effectively guaranteed.

Description

technical field [0001] The invention relates to a sampling device for deep-sea bottom organisms, in particular to a suction-type deep-sea bottom biology collection and in-situ maintenance system and a use method thereof. Background technique [0002] There are a large number of biological communities in the deep seabed. Scientific research on these deep seabed organisms is an important means for human beings to understand and study the evolution of marine life and the seabed environment. How to quickly, conveniently and effectively collect deep-sea submarine organisms to obtain first-hand living samples of deep-sea submarine biological science research, fully understand the biological resources in specific sea areas, and collect biological samples in different depths of seawater, which are marine resources. Major problems faced in the field competition. At present, our country is very backward in the in situ collection of deep-sea organisms. The main reason is that there is...

Problems solved by technology

At present, our country is very backward in the in-situ collection of deep-sea organisms, the main reason is that there is no effective sampling method for deep-sea organisms

At present, the only deep-sea biological sampling methods in my country are TV grabs and ROV, but these two can only collect sessile life or weak motility organisms, and cannot maintain the in-situ pressure and temperature of the deep sea, resulting in the collection of biological larvae from The seabed has died in the process of returning to the mother ship on the surface, which will have a great impact on the accurate research on the living conditions of the organisms in the seabed area and the seabed environment.
