Low-power microwave coring machine suitable for lunar rock and using method

Abstract

The invention provides a low-power microwave coring machine suitable for lunar rock and a using method. The low-power microwave coring machine comprises an equipment platform, wherein a supporting frame front plate and a supporting frame rear plate are slidably mounted on the equipment platform; the rear end face of the supporting frame rear plate is connected with the front end of a microwave generator mounted on the equipment platform; the rear end of the microwave generator is sequentially connected with a fixed waveguide, a rotating waveguide, a power divider and a drilling barrel; a high-precision sliding ring structure is mounted on the drilling barrel; gear clamping sleeves are arranged on the outer walls of the rotating waveguide and the drilling barrel and meshed with a transmission gear mounted on a rotating shaft; the rotating shaft is connected with a rotating driver; the rear end of a tunneling driver is fixed on the equipment platform; and the front end of the tunneling driver penetrates the supporting frame rear plate to be connected with the supporting frame front plate. Synchronous movement of a microwave system and the drilling barrel is realized, hard rock is drilled under the condition of meeting equipment miniaturization and low power, and the problems of failure in drilling and jamming of a drill can be avoided; through multi-port millimeter wave irradiation of the power divider, complete breaking of an outer ring of a rock core is realized while the rock core is not broken.

Description

technical field [0001] The invention belongs to the technical field of rock drilling, and in particular relates to a low-power microwave coring machine suitable for lunar rocks and a use method. Background technique [0002] Rotary drilling of hard rock is to drill forward through the torque and thrust applied to the drill bit by the drilling rig, but because of the hard rock, it often encounters the problems of drill sticking, drilling immobility and severe wear of the drill bit, especially sticking drill It will seriously affect the construction progress. [0003] The drilling of lunar rock layer materials is of great significance for the study of lunar resources. At present, the drilling work of the moon is mainly aimed at the loose covering layer on the surface of the moon - the lunar regolith, and the rock blocks mixed in the lunar regolith and the lunar rocks existing under the lunar regolith have high strength. On the moon, due to the effects of vacuum, weightlessne...

AI Technical Summary

Problems solved by technology

On the moon, due to the effects of vacuum, weightlessness, and large temperature changes, coupled with the impact of the limited transport capacity of the lander, it is difficult for drilling equipment to provide a large propulsion force, and it is difficult to replace the drill bit if it is stuck or damaged.

At the same time, it is difficult for the lunar lander to provide a lot of power to the auxiliary equipment, which brings great difficulties to the drilling of lunar rocks
