Description

Technical Field

[0001] This invention relates to the field of sterilization technology for polar drilling equipment, and in particular to an ultraviolet sterilization device for drilling hoses in subglacial lakes. Background Technology

[0002] Numerous subglacial lakes exist beneath polar ice caps. Due to their long-term enclosed state by the ice, these lakes and their sediments preserve pristine information about untouched ecological environments and microbial communities. This information allows for the study of paleoclimate change and the search for unknown life forms. The life forms within these subglacial lakes, which are subjected to high pressure, darkness, low nutrition, and low temperatures, are of significant scientific importance for studying the evolution of organisms in extreme environments. Drilling is the most direct method for obtaining subglacial lake water samples.

[0003] Currently, the fastest and most important drilling method for drilling subglacial lakes covered by ice is hot water drilling. Hot water drilling uses high-temperature hot water injected at high pressure through nozzles to melt the ice layer and drill through. Hot water drilling delivers high-temperature, high-pressure hot water from the surface to the bottom of the borehole via a hose. Lowering the hose from the surface to the bottom of the borehole may introduce surface microorganisms into the subglacial lake, contaminating the water samples and environment. To avoid contaminating the subglacial lake environment and obtain uncontaminated subglacial lake samples, it is necessary not only to clean the drilling tools but also to sterilize the outer surface of the hose lowered into the borehole.

[0004] Therefore, those skilled in the art urgently need an ultraviolet sterilization device for drilling hoses in subglacial lakes. Summary of the Invention
