The moon fidelity core-taking drilling device 100 comprises a drill rod 10 and an inner pipe 20, wherein the drill rod 10 is provided with a first hole 101 to form a first accommodating space 102, the inner pipe 20 is accommodated in the first accommodating space 102, the inner pipe 20 is provided with a second hole 201 to form a second accommodating space 202, the second accommodating space 202 is used for accommodating a drilled moon core, the drill rod 10 is provided with a plurality of first temperature regulating circuits 11, and the inner pipe 20 is provided with a plurality of second temperature regulating circuits 21. Specifically, the first hole 101 is a through hole, so that the moon core can enter the drill rod 10 through the first hole 101 and then enter the inner tube 20 through the second hole 201. The second hole 201 is a blind hole, and the opening direction of the second hole is the same as the drilling direction, namely, the second hole faces the interior of the moon, so that the moon core can be conveniently stored in a sealed manner after entering the second hole 201. The first hole 101 coincides with the axis of the second hole 201. Both the drill rod 10 and the inner tube 20 may be formed of a lightweight alloy having relatively high strength.
It will be appreciated that the lunar core coring drilling device 100 is susceptible to heat generation during the drilling of lunar cores, which absorbed heat in the lunar layers may heat up beyond the in situ temperature. In addition, due to the fact that the day and night temperature difference of the moon is large, when the outside air temperature is low, the heat of the moon core in the moon layer is easy to dissipate, and when the heat value of the moon core in the drilling process is lower than the dissipated heat value, the temperature of the moon core is lower than the in-situ temperature. The temperature regulating loop can be filled with a cooling medium to absorb heat, and can also be filled with a heat increasing medium to dissipate heat so as to maintain the in-situ temperature of the moon core.
The first temperature regulating loop 11 and the second temperature regulating loop 21 are arranged in the drill rod 10, so that heat generated in the process that the drill rod 10 drills the moon core is absorbed or released, the moon core in the inner tube 20 keeps the original position temperature, and the original position core component information and occurrence state information of the moon core are maintained.

Specifically, the extending direction 91 of the drill rod 10 and the extending direction 92 of the inner tube 20 are the drilling directions of the lunar fidelity coring drilling device 100. It will be appreciated that the first temperature-regulating circuit 11 extends in the extension direction 91 of the drill rod 10, i.e. the main flow direction of the medium of the first temperature-regulating circuit 11 is substantially the same as the extension direction 91 of the drill rod 10. The second temperature control circuit 21 extends in the direction of extension 92 of the inner pipe 20, i.e. the main flow direction of the medium of the second temperature control circuit 21 is substantially the same as the direction of extension 92 of the inner pipe 20. By arranging the first temperature regulating circuit 11 to extend along the extending direction 91 of the drill rod 10 and the second temperature regulating circuit 21 to extend along the extending direction 92 of the inner pipe 20, the first temperature regulating circuit 11 cools (heats) the whole drill rod 10, and the second temperature regulating circuit 21 cools (heats) the whole inner pipe 20, so that the absorption (release) efficiency of the first temperature regulating circuit 11 and the second temperature regulating circuit 21 on heat generated by the drilled moon core is improved, and the original position temperature of the moon core is maintained.
Specifically, a plurality of first temperature control loops 11 are arranged around the drill rod 10, the extending direction of the plurality of first temperature control loops 11 is the same as the extending direction 91 of the drill rod 10, and the plurality of first temperature control loops 11 are connected through a plurality of passages. In addition, the plurality of first temperature-adjusting circuits 11 may have one common inlet and one common outlet, or a plurality of inlets and a plurality of outlets. The second temperature control loop 12 is arranged in the same manner as the first temperature control loop 11.

Specifically, the outer periphery of the bit portion 12 is a tapered surface, the bit portion 12 is provided with an inner hole 121, the inner hole 121 corresponds to a part of the first hole 101, but the diameter of the inner hole 121 is smaller than that of the first hole 101 and is close to that of the second hole 201. The drill head 12 is provided with a hook-shaped protrusion 122, the hook-shaped protrusion 122 is located at one end of the inner tube 20 of the drill head 12 facing the interior of the moon, and the hook-shaped protrusion 122 is used for protecting the end of the inner tube 20 facing the interior of the moon. It will be appreciated that the heat generated by the drill rod 10 during drilling is primarily concentrated in the drill bit portion 12, and cooling of the drill bit portion 12 is important. The medium in the first temperature control loop 11 reaches the bit 12, enters the first temperature control portion 113, flows along the profile of the bit 12, and leaves the bit 12. The first temperature adjustment part 113 has a substantially "C" shape. By providing the first temperature control unit 113, the first temperature control unit 113 corresponds to the profile of the bit unit 12, and the medium can cool (heat) the entire bit unit 12, thereby improving the cooling (heating) effect of the bit unit 12 and facilitating maintenance of the home position temperature of the lunar core.
In one embodiment, referring to FIG. 1, the bit portion 12 is provided with a temperature measuring member (not shown) for measuring the temperature of the inner tube 20, the bit portion 12 and the moon core. Specifically, the temperature measuring element is disposed on the outer wall of the drill bit 12 of the drill rod 10 facing the inner tube 20, and does not protrude from the plane of the outer wall, and the temperature measuring element can be accommodated by slotting the outer wall, or can be disposed inside the drill bit 12. The temperature measuring member measures the temperature of each position of the inner wall of the inner tube 20, the temperature of the hook-shaped projection 122 of the drill head portion 12, and the temperature of the moon core. The temperature measuring piece can be used for contact temperature measurement and also can be used for non-contact temperature measurement such as infrared temperature measurement. By arranging the temperature measuring part, the temperature of the drill bit part 12, the inner tube 20 and the moon core is measured, so that the temperature of the moon core is conveniently controlled, and the in-situ temperature of the moon core is maintained.

Specifically, the higher the flow rate of the medium in the first temperature regulating circuit 11 is, the better the cooling (temperature increasing) effect of the first temperature regulating circuit 11 is, and the lower the temperature of the drill rod 10 is; the lower the flow rate of the medium in the first temperature control circuit 11, the less effective the cooling (warming) of the first temperature control circuit 11, and the higher the temperature of the drill rod 10. In addition, the control valve 30 has an opening and closing function. The medium is preferably a liquid. The control valve 30 has a function of opening and closing and regulating a flow rate. It will be appreciated that there is thermal conduction between both the drill pipe 10 and the inner pipe 20 and the moon core, which heats up by absorbing heat from the drill pipe 10 and the inner pipe 20 or cools down by emitting heat to the drill pipe 10 and the inner pipe 20. In addition, the properties such as composition, density and structure of the moon layers with different depths are different, so that the heat generated when the drill rod 10 drills moon cores with different depths is also different. At this time, the cooling effect of the first and second temperature control circuits 11 and 21 may be insufficient or interfered, and the temperature of the moon pool is higher or lower than the home position temperature.

In one embodiment, referring to fig. 1, the core drilling device 100 further includes a claw (not shown) disposed at an end of the inner tube 20 near the bit 12, and when the core drilling device 100 finishes coring and is far away from the lunar layer, the claw breaks the lunar core, so that the lunar core is separated from the lunar layer and is accommodated in the second accommodation space 202. Specifically, the jaws are fixedly connected to the inner tube 20. The clamping jaws have the characteristic of easy entry and difficult exit, and when the moon core enters the inner tube 20 through the clamping jaws, the moon core is less in resistance; when the moon core leaves the inner tube 20 through the claws, the moon core is subjected to a large resistance and is difficult to leave the inner tube 20, so that the claws have a certain supporting function. In addition, the jack catch is suitable for drilling the lunar soil, when drilling the lunar soil, the jack catch is not easy to support because the lunar soil structure is loose, the jack catch can be replaced by the self-sealing ring, and the lunar soil is clamped and broken by the self-sealing ring and is sealed to support the lunar soil. By providing the claw, when the lunar fidelity coring drilling device 100 finishes coring and is far away from the lunar layer, the claw blocks the lunar core, so that the lunar core is conveniently taken away from the lunar layer by the inner pipe 20.
Referring to fig. 1, an embodiment of the present invention further provides a lunar fidelity coring drilling system, which includes a driving element and a lunar fidelity coring drilling device 100 provided by an embodiment of the present invention, the driving element is connected to the lunar fidelity coring drilling device 100, and the driving element is configured to drive the lunar fidelity coring drilling device 100 to rotate to drill a lunar core. By adding the lunar fidelity coring drilling device 100 provided by the invention into the lunar fidelity coring drilling system, the lunar fidelity coring drilling system can absorb friction heat generated by drilling or release heat to the lunar core in the process of drilling the lunar core, so that the lunar core keeps the in-situ temperature, and the in-situ rock core component information and the occurrence state information of the lunar core are favorably maintained.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
