Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] To better understand the technical content of the present invention, the technical solution of the present invention will be further introduced and explained below with reference to specific embodiments.

[0032] like Figure 1 The diagram shown is a cross-sectional view of a preferred embodiment of the present invention. An extraterrestrial drilling and water extraction device includes a laser-assisted rock breaking and heating water extraction section, an external rock cuttings heating water extraction section, and the device body.

[0033] The laser-assisted rock-breaking and water-extraction section of the aforementioned extraterrestrial drilling and water-extraction device includes a drilling device 11, a laser device 17, and an inner tube heating device 16. These three devices are connected in series via wires. A main power supply 1 is connected to a control device 2, the drilling device 11, the laser device 17, and the inner tube heating device 16 via wires to provide power. The drilling device 11, the laser device 17, and the inner tube heating device 16 are each connected to the control device 2 of the device body via signal lines, and the control device 2 controls the operation of these devices. The drilling device 11 uses a spiral drill rod 15 with an outer tube. The laser device 17 and the inner tube heating device 16 are arranged in the hollow inner tube 19 of the drilling device 11. The drilling device 11 includes a spiral drill rod 15, a drill bit 18, an outer tube 14, a hollow inner tube 19, a feed motor 6, and a conductive slip ring 10. Brushes are arranged in the conductive slip ring 10 to prevent wire entanglement. During drilling, the feed motor 6 in the drilling device 11 provides power for downward drilling, while the laser device 17 simultaneously assists in mechanical rock breaking. The electric pulley 7 allows the drill bit to move up and down along the slide rail 8 on the fixed holder 9. The discharged rock cuttings are divided into two parts: one part is discharged directly from the outer pipe outlet 13 through the auger drill rod 15, and the other part enters the hollow inner pipe 19. As the drilling depth increases, the rock cuttings continuously compress the filter screen 16-6, and the contraction tube 16-2 moves upward along the inner wall of the drill rod with the pulley 16-5. The upper part of the filter screen 16-6 is the contraction tube 16-2, whose length can be freely contracted. The internal rock cuttings are heated at high temperature by the heating tube 16-4 in the inner pipe heating device 16, and water vapor is transported to the collection device 20 through the pipeline A28.

[0034] The external rock cuttings heating and water extraction section of the aforementioned extraterrestrial drilling and water extraction device includes a conveying device 27, an external heating device 3, and a collecting device 20.

During drilling, some rock cuttings move upwards with the auger rod 15. The brush 12 in the outer tube 14 can block and sweep away the rock cuttings, which are then discharged from the outer tube outlet 13. The conveying device 27 collects the external rock cuttings. After filling a soil collection chamber 27-5, the moving shaft 27-3 is rotated horizontally 180° by the motor B27-2 and then rises to connect with the external heating device 3. The conductive sensor 5 can detect the conductive plate 27-6 of the conveying device 27 and transmit the detection signal to the control device 2. The control device 2 can then transmit the signal via the conductive sensor. The detection signal from sensor 5 then controls the power supply to heating element A4 and heating element B27-1, heating the rock debris in the soil collection chamber 27-5 to achieve water and soil separation of external rock debris; then the conveying device 27 is driven by motor B27-2 to move the rotating shaft downwards, and the flipping shaft 27-4 flips the soil collection chamber 27-5 up and down to discharge the waste soil from the waste soil outlet 26; water vapor enters the water collection tank 21 in the collection device 20 through pipe B25.

The flipping shaft 27-4 is hinged to the moving shaft 27-3, and the soil collection cavity 27-5 can be flipped up and down 180°.

[0039] Preferably, the heating element B27-1 in the conveying device 27 and the heating element A4 in the external heating device 3 are silicone heating elements with an operating temperature between 150 and 200°C.

[0040] like Figure 2The diagram shows a cross-sectional view of the drill bit 18, which contains a laser device 17. The laser device 17 includes a laser emitter 17-1, an optical fiber 17-2, an optical fiber sleeve 17-3, a fixed connector 17-4, and a laser head 17-5.

The power is between 40 and 100W.

[0041] like Figure 3 The diagram shows a cross-sectional view of the inner tube heating device 16, which includes a fixed valve 16-1, a contraction tube 16-2, a protective shell 16-3, a heating tube 16-4, a pulley 16-5, and a filter screen 16-6. The fixed valve 16-1 is located at the top of the drill rod. The heating tube 16-4 has a protective shell 16-3 inside and extends along the inner wall of the drill rod. The upper half of the contraction tube 16-2 is a telescopic rubber tube that can be extended and retracted, while the lower half is a straight metal tube, which has a significant heat transfer effect and is conducive to the transport of water vapor. The upper end of the contraction tube 16-2 is fixed to the drill rod, and the lower end is connected to the pulley 16-5. It slides up and down on the inner wall of the drill rod driven by the pulley 16-5. The bottom is equipped with a filter screen 16-6. The heating tube 16-4 can heat the internal rock cuttings to achieve water and soil separation. Water vapor is transported by the contraction tube 16-2, and waste soil is filtered out by the filter screen 16-6.

[0042] like Figure 4 The diagram shows a cross-sectional view of the conveying device 27. In practice, the soil collection chamber 27-5 is a cylindrical cavity with a partition wall inside. Inside the partition wall is a heating element B27-1, which is a silicone heating element with a working temperature between 150 and 200°C. The conveying device 27 collects external rock debris. After filling the soil collection chamber 27-5, the motor B27-2 drives the moving shaft 27-3 to rotate horizontally 180° and then rise to connect with the external heating device 3, heating the rock debris in the soil collection chamber 27-5 and achieving water-soil separation. Then, the conveying device 27 moves downwards driven by the motor B27-2, and the tilting shaft 27-4 tilts the soil collection chamber 27-5 up and down, discharging the waste soil from the waste soil outlet 26. The tilting shaft 27-4 can then tilt again for the next collection.

6. The method for drilling soil and extracting water from extraterrestrial bodies according to claim 5, characterized in that, In the external rock cuttings heating water extraction route, steps 2.2 to 2.4 can be repeated to achieve multiple water extraction cycles.
