Hot water core drill used at glacier

Abstract

The invention discloses a hot water core drill used at a glacier. The hot water core drill comprises a plunger pump, a two-way pipe, a heat insulation pipe, an ice core pipe, a drill bit and a flower divider, wherein the plunger pump is arranged in a pump storage pipe, the upper end of the plunger pump is connected with a water outlet pipe, the lower end of the plunger pump is connected with a water absorption pipe, the two-way pipe is connected to the lower end of the pump storage pipe, the lower end of the two-way pipe is connected with the heat insulation pipe, the ice core pipe is inserted in the heat insulation pipe, the drill bit is arranged below the heat insulation pipe and the ice core pipe, the flow divider is arranged on the lower portion of the two-way pipe and at the top end of the ice core pipe, the top end of the flow divider is connected with a hot water injection pipe, the lower portion of the flow divider is connected with a plurality of drainage pipes which are arranged in a gap between the heat insulation pipe and the ice core pipe, and hot water injected by the hot water injection pipe at the top end of the flow divider is injected into the drainage pipes through the flow divider. The hot water core drill has the advantages that due to the fact that the hot-melting drill bit is adopted for tapping and drilling of the hot water drill, and molten water is extracted to serve as a raw material of the hot water drill, cost is reduced, and the energy utilization rate is increased.

Description

technical field [0001] The invention relates to a core drilling tool, in particular to a hot water core drilling tool used in glaciers. Background technique [0002] At present, hot water drilling is an important part of the Antarctic ice hot water drilling technology. Current hot water drilling in Antarctic ice is done by melting the ice with hot water and without coring. Ordinary drilling operations are done by mechanical drilling, which consumes a lot of energy and the energy utilization rate is not high when using mechanical drilling. The hot water drill is fast and efficient with its unique drilling method. Drilling and coring through hot water drill bits will greatly improve the efficiency and energy utilization of drilling and coring. Contents of the invention [0003] The purpose of the present invention is to solve the problem of how to improve the drilling and coring efficiency and energy utilization rate in the Antarctic ice drilling process, and to provide a...
