Pressure-maintaining and heat-preserving sampling transfer system and sampling transfer method for marine benthos

Abstract

The invention discloses a pressure-maintaining and heat-preserving sampling transfer system for marine benthos. The system comprises a pressure-maintaining assembly, a sampling assembly and a circuitbarrel, wherein the sampling assembly is inserted into the pressure-maintaining assembly and is connected with a culture kettle; an inlet sealing assembly is arranged at an inlet in the middle of thepressure-maintaining assembly, a heat-preserving assembly is bonded on the outer wall in the middle of the pressure-maintaining assembly, a pressure compensation device and a bait cylinder are arranged on the outer wall at the bottom of the pressure-maintaining assembly, the pressure compensation device is communicated with the pressure-maintaining assembly, and the bait cylinder is communicated with the pressure-maintaining assembly through a switch valve; a temperature sensor and a pressure sensor are arranged on the inner wall of the pressure-maintaining assembly; the circuit barrel is installed on the outer wall of the pressure-maintaining assembly, a power supply and a controller are arranged in the circuit barrel, and supplies power to the heat-preserving assembly, a controller, thetemperature sensor and the pressure sensor, and the controller is connected with each of the temperature sensor, the pressure sensor and the heat-preserving assembly. The pressure-maintaining and heat-preserving sampling transfer system disclosed by the invention can realize the trapping and pressure-maintaining and heat-preserving culture of the marine benthos and can effectively ensure the in-situ vital characteristics of the marine benthos.

Description

technical field [0001] The invention relates to a deep-sea biological sampling device, in particular to a pressure-preserving and heat-preserving sampling transfer system and a sampling transfer method for seabed organisms. Background technique [0002] The total area of ​​the world's oceans is about 361 million square kilometers, accounting for 71% of the earth's surface area. The seabed not only contains rich mineral resources, but also breeds a wide variety of unknown biological resources. The exploration of seabed biological resources is an important link in revealing the mysteries of human life and the origin of genes, and can greatly promote the development of life sciences. Submarine biological sampling tools are necessary technical means to carry out seabed environmental research, sampling and exploration of seabed biological resources. During the process of sampling and experiment, because the original living environment of organisms could not be maintained, the co...

Problems solved by technology

Submarine biological sampling tools are necessary technical means to carry out seabed environmental research, sampling and exploration of seabed biological resources. During the process of sampling to the experiment, because the original living environment of the organisms could not be maintained, the collected seabed organisms died in the process of returning to the surface mother ship from the seabed, which is very unfavorable for the study of the species characteristics of the seabed organisms
