Electric ice scraping device for ice core pretreatment

Abstract

The invention discloses an electric ice scraping device for ice core pretreatment. The electric ice scraping device for ice core pretreatment is characterized in that a handle is connected with a carbon steel tool bit set or an aluminum oxide / ceramic tool bit set, the carbon steel tool bit set or the aluminum oxide / ceramic tool bit set is arranged in a cylindrical flake ice colleting box through stretching-in holes of the flake ice colleting box and is in contact with an ice sample, the two sides of the flake ice colleting box are connected with two side doors through a first hinge and a second hinge, and the stretching-in holes are formed in the centers of the side doors. The electric ice scraping device for ice core pretreatment is convenient to assemble and disassemble; compared with manual ice scraping, both the degree of uniformity and the efficiency are improved, manpower resources and material resources are saved, time is saved, manufacturing cost is quite low, and the electric ice scraping device is suitable for outer wall stripping during ice core pretreatment. By the adoption of the electric ice scraping device for ice core pretreatment, the situation that the ice sample is exposed in air for a long time is effectively avoided, and the probability of secondary pollution caused when the ice sample is exposed in the air is greatly lowered.

Description

technical field [0001] The invention belongs to the field of machinery, and specifically refers to an efficient and pollution-free electric ice scraping device used in the pretreatment of ice core research. Background technique [0002] Ice core records have the characteristics of good fidelity (low temperature environment), high resolution (up to one year), long record sequence (up to hundreds of thousands of years) and large amount of information. important research tool. Ice core climate records can make up for the shortage of meteorological stations in mountainous areas, their uneven distribution and the short period of data accumulation. At the same time, physical, chemical, and biological information can also be extracted from ice cores. These records preserve high-resolution paleoenvironmental signals, which can be used to test the influence of climate forcing factors (such as greenhouse gases and solar activities), and provide information on the impact of atmospheri...

AI Technical Summary

Problems solved by technology

Ice samples have been exposed to the air for a long time, and the environment is different from the glacier area, which may increase the probability of secondary pollution of the ice core and is not conducive to its preservation

At the same time, it is difficult to grasp the uniformity of sample peeling with artificial ice shaving. The repeated contact of the ice scraper (scalpel or ceramic knife) with the test bench will cause damage to the blade, and the consumption of materials is large. Manual ice shaving is time-consuming and labor-intensive. This slows down the progress of ice core processing and analysis, and also increases the cost of ice core research.

In addition, working in the ice storage for a long time will cause great harm to the staff
