Background
Currently, polar ice caps and glaciers contain ancient ice layers that have been orderly assembled as snow falls down for several hundred years, and dust particles, soluble chemicals, and gases entrapped in ice contained in these ancient ice layers are commonly used to study past climate change. The ice core contains rich climate information, and can provide pure past greenhouse gases and accurate old climate information. In order to obtain ice cores, scientists in various countries have designed various core drills and put them into use in polar regions. The hot water core drilling technology has the characteristics of high drilling speed, no drilling fluid pollution and the like, and is widely applied to ice layer core drilling. However, one disadvantage of hot water core drilling is that it results in a very irregular surface of the ice core because of the thermal effect of the hot water on the ice core. Conventional core drilling tools employ a snap-off to snap off the ice core and then the drill is pulled up to the surface with the ice core. However, the ice core obtained by adopting the hot water coring drilling technology is uneven in surface and large in diameter change, and can not be cut off successfully by the clamping device in time, so that the phenomenon that the ice core pipe is not full or the ice core pipe is not filled in the ice core pipe often occurs when the drill is lifted. Therefore, a novel core drill is required to be designed, the problem of difficult acquisition of irregular ice cores is solved, and the collection efficiency of the ice cores is improved.
