Problems solved by technology

[0002] Drilling sampling device is an important tool for lunar exploration. Its drilling tool coring mechanism faces dense and deep lunar soil, and the interaction between drilling tool and lunar soil will generate a lot of heat; due to the influence of vacuum environment and lunar soil The thermal conductivity of the soil is extremely poor. In addition, the lunar surface sampling work process is not drilling with cutting fluid dry powder, resulting in extremely high temperature of the drill pipe and drill bit, especially for the drill bit and non-metal soft coring mechanism. Ineffective or even unable to continue to drill into the core

Abstract

The invention discloses a lunar-environment-simulated cutting test device. According to the lunar-environment-simulated cutting test device, a vacuum environment existing during lunar surface drilling is simulated by adopting a vacuum tank, the structure of a lunar surface is simulated by adopting a drilling load, and a heat-insulating drilling load in a lunar vacuum environment is simulated more really by using a heat insulation technology; the control on drilling parameters and procedures is carried out on drilling sampling during the process of cutting, the drilling parameters and drilling temperature can be monitored, acquired and analyzed, the temperature distribution and the highest temperature limit of a drilling tool are determined, and the vacuum seal for a drilling sampling device during the process of drilling is realized through a magnetofluid sealing device; and the visualization of a vacuum device is realized by adopting an observation window. The lunar-environment-simulated cutting test device also can be applied to the test and development of other drilling unmanned autonomous samplers for deep space exploration in an expanding manner; and in addition, the lunar-environment-simulated cutting test device also has a wide application prospect in the field of vacuum sealing and precise measurement.

Description

technical field [0001] This project involves a cutting test device, especially a cutting test device in a simulated lunar environment, which belongs to the field of deep space exploration technology. Background technique [0002] Drilling sampling device is an important tool for lunar exploration. Its drilling tool coring mechanism faces dense and deep lunar soil, and the interaction between drilling tool and lunar soil will generate a lot of heat; due to the influence of vacuum environment and lunar soil The thermal conductivity of the soil is extremely poor. In addition, the lunar surface sampling work process is not drilling with cutting fluid dry powder, resulting in extremely high temperature of the drill pipe and drill bit, especially for the drill bit and non-metal soft coring mechanism. Ineffective or even unable to continue drilling into the core. With the development and deepening of my country's deep space exploration, drilling unmanned autonomous sampling and re...
