Therefore, a drilling tool is urgently needed to directly carry out upward hole drilling and observation research from bottom to top on the ice layer at the bottom of the ice rack.
In addition, some underwater vehicles can not receive water surface information all the time due to the obstruction of a thick ice layer of the ice rack after long-time underwater navigation and reach positions far away from the front edge of the ice rack and enter deep areas of the ice rack. Therefore, the underwater vehicle must launch a communication buoy to the sea surface at a certain effective communication distance for signal transmission and reception, so as to realize communication with the command mechanism. In order to quickly release the buoy, a drilling technology capable of quickly drilling through an ice layer from bottom to top at the bottom of the ice rack is urgently needed.
Mechanical rotary drilling is a drilling method with the most efficient structure in the current ice layer drilling, but when an ice layer with higher drilling temperature is drilled, the ice layer is melted after being cut and heated and then is frozen on a cutter head again, so that the cutter edge becomes dull and the drilling cannot be performed. In order to solve the disadvantage of mechanical rotary drilling, an electric heating rod is arranged in the drill bit, the electric heating rod (wire) is used for heating the drill bit, the high-temperature drill bit can help to melt and cut an ice layer, and the efficiency is higher.
Aiming at the technical background, a drilling rod-free hole-lifting hot melting rotary drilling system capable of automatically climbing by utilizing buoyancy is developed, and the drilling system can be utilized to quickly drill holes upwards to obtain ice cores at the bottom of the ice frame, so that scientific research on related ice cores at the bottommost part of the ice frame is developed.
