Hot-gas ice layer core-taking drilling tool

Abstract

The invention discloses a hot-gas ice layer core-taking drilling tool. The hot-gas ice layer core-taking drilling tool comprises a negative pressure vacuum water pump, a water storage tank, a samplingtube, a heating tank and a drill bit. The negative pressure vacuum water pump is arranged at the top of the water storage tank and communicates with an inner cavity of the water storage tank, the sampling tube and the drill bit are arranged on the lower portion of the water storage tank in sequence, and the dill bit is fixedly connected to the bottom of the sampling tube. The water storage tank communicates with a plurality of water absorption tubes, water inlets of the multiple water absorption tubes are arranged around the drill bit in a surrounding mode, the heating tank is arranged belowthe sampling tube in a sleeving mode, and a plurality of air inlet pipes are arranged at the upper end of the heating tank in a communicating mode. Through the air inlet pipes, cold air can be fed into an inner cavity of the heating tank to be heated by the heating tank, the heating tank further communicates with a jet opening, the jet opening is formed in the lower part of the heating tank, and the heated air in the inner cavity of the heating tank is sprayed out by the jet opening. The hot-gas ice layer core-taking drilling tool has the beneficial effect that snow and ice particles melt or sublimate rapidly under the impact of hot gas so that the drilling efficiency can be faster. The hot gas drilling is clean and environmental protection, and the hot-gas ice layer core-taking drilling tool has great use values in the special polar environment.

Description

technical field [0001] The invention relates to an ice core drilling tool, in particular to a hot air ice core drilling tool. Background technique [0002] At present, most of the commonly used rapid ice drilling technologies are hot-melt drilling or hot-water drilling. Higher, the highest medium temperature can only reach 30-70°C, and the energy utilization rate is less than 70%, which greatly wastes manpower and material resources. In addition, the structure of the transmission mechanical ice drilling tool is relatively complex, the surface equipment is bulky, and the drilling speed is greatly affected by the nature of the ice layer. During the drilling process, the drilling tool often stops suddenly or even gets stuck. The above problems are still present. has not yet been fundamentally resolved. Contents of the invention [0003] The object of the present invention is to provide a hot air ice core drilling tool for solving the problem of excessive energy loss of hot ...
