Embodiment Construction

[0020] The design idea of ​​the present invention will be described below in combination with specific implementations, so that the examiner can understand the characteristics of the present invention. The detailed description is as follows:

[0021] A drilling tool for extracting water resources from the surface of an extraterrestrial celestial body mainly includes a drill pipe, a drill bit, a light guide mirror and a flexible sealing cover. The drill pipe adopts a segmented cavity structure. The upper section is a fine thread structure, which is connected with the rotating sleeve to provide rotational torque; the middle section is a smooth outer surface structure, and the lower section is a helical structure. The lower section of the helical structure is called a blade. Helical structure configuration, the blades are made of materials with high strength and strong thermal conductivity (such as metal alloys). The blades not only extract the surface soil, but also play the role...

Abstract

The invention provides a drilling tool device and drilling method for obtaining an extraterrestrial celestial body surface water source. According to the device provided by the invention, a drilling bit is drilled in and surface-layer soil is drilled through a blade; focused sunlight is transmitted to a cavity in a drilling rod by utilizing a light-guide mirror surface, so that the supply of energy source heat is realized; the blade has a fin function to transmit the heat to the periphery to drill the soil, and water steam volatile matters are produced; then the water steam volatile matters enter the cavity of the drilling rod through an air hole of the drilling rod, are gathered on a water steam outlet and then are discharged, so that the extraterrestrial celestial body surface water source is obtained. The drilling tool device provided by the invention has the advantages of relatively simple structure, relatively low weight and power consumption requirements and high function integration level, and the extraterrestrial celestial body surface water source can be effectively obtained.

Description

technical field [0001] The invention relates to a drilling tool device and a drilling method for obtaining water resources on the surface of extraterrestrial celestial bodies, which can be used as an important means for extracting water resources in frozen soil, ice layers, and soil hydrates of extraterrestrial celestial bodies such as the moon, asteroids, and Mars. At the same time, the system can also be used to extract other volatiles in the soil of extraterrestrial objects. Background technique [0002] With the deepening of manned exploration of near-Earth objects in the future, the demand for water resources for human survival is increasing day by day, and the in-situ acquisition of water resources is the key solution. [0003] At present, NASA of the United States has proposed a strategic plan to use drilling hydrate lunar soil for centralized heating and volatilization to collect water vapor for water resource extraction. The scheme mainly covers drilling tools, hea...
