Making device for artificial ice core

Abstract

The invention relates to a making device for an artificial ice core. A double-layer sleeve structure consists of an inner pipe, a long heat-preservation outer pipe and a short heat-preservation outer pipe; one end of the long heat-preservation outer pipe is closed; the inner pipe is formed by mutually butting two semicircular pipes; one end of the inner pipe is imbedded in the long heat-preservation outer pipe, while the other end of the inner pipe is connected into the short heat-preservation outer pipe in a sleeving manner; open ends of the long heat-preservation outer pipe and the short heat-preservation outer pipe are butted, enwrapped and closed. The making device for the artificial ice core is simple in structure, and is easy to process. By utilizing the device, an artificial ice core which is high in quality and full in size (consistent with the diameter and the length of a natural ice core) can be made; the artificial ice core is prevented from being polluted; the reliability and the accuracy of the blank control study of an ice core can be guaranteed.

Description

technical field [0001] The invention relates to an artificial ice core making device, in particular to an artificial ice core making device for blank comparative research in ice core research. Background technique [0002] Polar and mountain glaciers are formed by the accumulation and compaction of snow layers over tens of thousands of years into ice. Ice cores are continuous cylindrical ice bodies drilled on glaciers using ice core drilling rigs. Scientists extract various physical, chemical and biological information from ice cores to invert the characteristics of climate and environmental changes at regional and global scales in different periods, providing an important scientific basis for predicting future climate and environmental changes. Due to the very low content of various chemical information (such as various ions, particles, and trace elements, etc.) in ice cores, the exterior of ice core samples is inevitably subjected to various impacts during drilling, trans...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the small size of the plastic tube used (such as 3 cm in inner diameter and 30 cm in length) and no external insulation layer, the artificial ice core freezes quickly under the action of low temperature, and the artificial ice core produced in this way contains more air bubbles. The artificial ice core is relatively brittle, and it is easy to break and cause pollution during cutting and decontamination

[0005] 2. Since the artificial ice cores produced are relatively small, their diameter and length are smaller than the actual ice cores, and they are not stored, cut,
