Intelligent visual capturing and pressure maintaining device for deep sea benthos sampling

Abstract

The invention discloses an intelligent visual capturing and pressure maintaining device for deep sea benthos sampling, which comprises a sampling capturing mechanism, a pressure maintaining mechanism, a 360-degree deep water panoramic camera for monitoring deep sea benthos and a cable for transmitting electric power, and is characterized in that the sampling capturing mechanism comprises a capturing unit and a storage unit; a water pump paddle used for providing reverse siphon force for the interior of the capturing cylinder when the capturing cylinder extends out is arranged at the connecting port of the pressure-resistant cylinder, and a pressure maintaining driving device used for opening the sealing cover when the collecting port is opened and closing the sealing cover when the collecting port is closed is arranged in the box body; the automatic control mechanism is used for controlling the in-situ pressure in the pressure maintaining cavity in the rising process after capturing is completed. The benthic organism capturing device is simple in structure, benthic organisms can be actively, flexibly and efficiently captured, the organisms are prevented from escaping, and the survival rate of the organisms is increased.

Description

technical field [0001] The invention relates to the technical field of deep-sea biological sampling, in particular to an intelligent visual capturing and pressure-holding device for sampling deep sea-dwelling organisms. Background technique [0002] With the development of land resources, people gradually began to pay attention to the development of marine resources. Since the beginning of the 21st century, the competition for marine resources has become more intense, and countries all over the world are vying to advertise themselves as marine powers. The deep sea not only contains rich mineral resources, but also breeds a wide variety of unknown biological resources. The exploration of deep-sea 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. A large number of seabed microbial samples provide precious samples for biodiversity research and genetic research. ...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned patented technology provides technical support for deep-sea biological sampling, and greatly promotes the development of marine deep-sea biological exploration and research. Sampling the vital signs of organisms, but there are still some defects. First, due to the huge pressure on the deep seabed, the current "trapping" method for benthic organisms cannot easily capture living organisms such as blind fish and blind shrimp. It is a passive capture method, which results in low capture efficiency of deep-sea marine organisms, and cannot actively capture the organisms that need to be captured, resulting in the current deep-sea biological sampling equipment that cannot meet the needs of flexible capture. Second, the existing The traps cannot achieve continuous capture of living organisms. When opening the hatch for secondary capture, it is often easy to cause the escape of captured organisms, which makes it difficult to guarantee the type or quantity of sampling.

Third, although the current pressure-holding sampling equipment can ensure that the obtained biological samples are basically maintained at the in-situ pressure, greatly improving the survival rate of organisms, but after the capture device captures the living biological samples and transports them to the pressure-holding equipment, The structure of the equipment is complex, the production cost is high, the equipment is prone to failure, and it is difficult to ensure a good pressure holding function, which makes it difficult to guarantee the survival rate of living organisms

Fourth, most of the current traps for deep sea-dwelling organisms are bulky and complex in structure, and the capture process is inflexible
