Embodiment 1

[0041] Such as Figure 1-Figure 2 As shown, a microwave-assisted rock-breaking device for simulating the drilling process of the moon-based environment, a microwave-assisted rock-breaking device for simulating the drilling process of the moon-based environment includes: a core barrel 12, a lunar imitation vacuum module 17, a microwave module, a drilling Module and data acquisition module; the rock 11 to be broken is placed in the core barrel 12, and rocks with different materials and different hardness and other physical properties can be selected in the experiment to simulate different lunar rock materials.

[0042] The moon-like vacuum module 17 is arranged outside the core barrel, and is used to evacuate the inside of the core barrel 12 to simulate the moon-based environment. Generally, a vacuum extraction device is used for vacuuming. In order to maintain the vacuum environment in the core barrel 12, the rock The core barrel 12 is a vacuum-tight container capable of withst...

Embodiment 2

[0057] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the microwave module and the drilling module are all arranged on the right side of the core barrel 12, the microwave feed port 8 irradiates the rock from the right side, and the cutting teeth 9 drill from the right side. Rock 11 and sampled. In this way, the magnetron 1 is facing the microwave feed port 8, and the magnetron 1 is connected with the input port of the circulator 5 through the rectangular waveguide 3, and the output port of the circulator 5 is connected with the coaxial waveguide 4, and the coaxial waveguide 4 extends into the rock core The barrel 12 is connected to the microwave feed port 8, and the waveguide converter 7 is not needed to convert the transmission direction of the microwave.

Abstract

The invention discloses a microwave-assisted rock breaking device and method for simulating a moon-based environment drilling process. The microwave-assisted rock breaking device comprises a rock core cylinder, a moon-simulating vacuum module, a microwave module, a drilling module and a data acquisition module; rock to be crushed is placed in the rock core cylinder; the moon-simulating vacuum module is used for vacuumizing the interior of the rock core cylinder to simulate a moon-based environment; the microwave module is used for generating microwaves and transmitting the microwaves to the rock to be measured to assist the drilling module in sampling the rock; and the drilling module penetrates through the rock core cylinder to drill and sample the rock in the rock core cylinder. According to the microwave-assisted rock breaking device for simulating the moon-based environment drilling process, through organic integration of the moon-simulating vacuum module, the drilling machine and the microwave module, a microwave combined drilling machine efficient rock breaking test under the simulated moon high-vacuum environment is achieved, and technical and theoretical supports are provided for safe and efficient development of moon resources and space.

Description

technical field [0001] The patent of the invention relates to the fields of lunar coring prospecting, mining technology and geotechnical engineering, and is specifically a microwave cooperative drilling rig combined rock breaking device in an indoor scale simulated lunar environment. Background technique [0002] In deep space exploration, rock fragmentation and other issues are inevitably involved in drilling and coring, resource exploration, and infrastructure construction. Studies have shown that the loose lunar soil in the shallow layer of the moon, while extending to the deep part of the moon, is mainly composed of Composed of hard components such as meteorites and basalts, traditional mechanical rock-breaking equipment is no longer suitable for efficient rock-breaking processes in deep space due to its high energy consumption, large size, and low efficiency. Therefore, rock fragmentation has become an urgent problem to be broken through, and has become an important pro...
