Embodiment Construction
[0020] The design idea of the present invention will be described below in conjunction with specific embodiments, so that the examiner can understand the characteristics of the present invention. The detailed statement 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 of he...
