TECHNICAL FIELD
[0001] The application belongs to the technical field of polar drilling, and particularly relates to a full-link supply system capable of performing bionic sampling while drilling. BACKGROUND
[0002] The polar ice cap is formed due to the fact that the accumulation of snowfall is greater than the melting amount in the polar low-temperature environment, and through long-term compaction and crystallization, a thick ice body is finally formed. It usually takes hundreds or thousands of years from snow to glacier ice, and the average 2200-meter-thick ice layer in the Antarctic is formed in millions of years.
[0003] The bubbles sealed in the ice core are the only samples that can directly measure the concentrations of greenhouse gases such as carbon dioxide, methane and nitrous oxide in the atmosphere in the past hundreds of thousands of years, providing a key historical background for understanding current climate change. The impurities (such as sulfate, nitrate, dust, volcanic ash and black carbon) in the ice core record the intensity of past volcanic activity and the history of atmospheric circulation patterns. It can be said that by obtaining and analyzing the ice core, we can directly observe the climate and environmental changes on Earth for hundreds of thousands to millions of years. The drilling of the polar ice cap has been started as early as the 1950s, and the United States drilled the first deep ice core in the Antarctic and the North Pole in the late 1960s. Subsequently, more reliable hot melt drills, electric mechanical drills and other drilling technologies have been developed, and the extracted ice core successfully revealed the climate change record in the northern and southern hemispheres in the past million years.
[0004] The traditional drilling technology needs to transport the ice core sample to the ground laboratory for detection, and the gas may escape or the sample may be contaminated during storage and transportation, and real-time in-situ analysis cannot be achieved. In addition, the uneven arrangement of the heating wire of the conventional hot melt drill head leads to low heat transfer efficiency, and a cold end is easily formed, which restricts the drilling efficiency.
