Embodiment Construction

[0024] see Figure 1 to Figure 5 Shown:

[0025] The uphole coring system at the bottom of the ice shelf based on the underwater robot provided by the present invention includes an underwater robot 1, a core drilling tool 2, a water tank 3, a boiler 4 and a control system 5, wherein the core drilling tool 2 is assembled in the underwater On the shell on the upper part of the robot 1, the water tank 3, the boiler 4 and the control system 5 are all arranged in the inner cavity of the underwater robot 1, the water tank 3 and the boiler 4 are connected by a water pipe, and the water for the boiler 4 is input by the water tank 3. The boiler 4 and the core drilling tool 2 are also connected by a water pipeline, and a high-pressure pump 6 is arranged on the connecting pipeline. The boiler 4 provides hot water for drilling for the core drilling tool 2. The switch of the high-pressure pump 6 and the boiler 4 All are connected with the control system 5, and the control system 5 control...

Abstract

The invention discloses an ice-shelf-bottom uphole coring system and method based on an underwater robot. The coring system comprises the underwater robot, a coring drilling tool, a water tank, a boiler and a control system, wherein the coring drilling tool is assembled on a shell at the upper portion of the underwater robot, the water tank, and boiler and the control system are arranged in an inner cavity of the underwater robot, the water tank is communicated with the boiler through a water pipe, and water used by the boiler is input by the water tank. The coring method includes the steps that 1, the underwater robot is put into water to work; 2, uphole drilling work from bottom to top is carried out; 3, the underwater robot is controlled to return to the sea level. The ice-shelf-bottomuphole coring system and method based on the underwater robot has the advantages that the technical scheme is unique in design, the theory is clear, a traditional coring drilling method from top to bottom is broken through, coring can be carried out in the interface between ice-shelf-ice-core-researching critical regions-ice shelf bottom and the sea, the whole ice shelf does not need to be drilled, and wasting of manpower and material resources is greatly reduced.

Description

technical field [0001] The present invention relates to a system and a method for coring from an upward hole at the bottom of an ice shelf, in particular to a system and a method for taking a coring from an upward hole at the bottom of an ice shelf based on an underwater robot. Background technique [0002] At present, the polar regions and the ocean play an extremely important role in the global climate system due to their global cold source and vastness respectively. Ice shelves are the link between the ocean and the polar ice caps and have important effects on both systems. The structure of the ice shelf and the freeze-thaw process at the bottom will directly affect the stability and movement of the ice shelf, thus having an important impact on the continental ice sheet, oceanic water mass and circulation. Based on this, relevant departments have included the interaction of Antarctic ice shelves with ocean water mass and circulation in the scientific frontier research pl...
