Description

Technical Field

[0001] This invention relates to the field of extraterrestrial environment detection technology, specifically to a spiral drilling and recovery anchoring device and detection equipment for extraterrestrial environments. Background Technology

[0002] Existing detection equipment for the extraterrestrial environment is generally positioned by astronauts stepping on it, without anchoring. This results in the equipment being relatively small, with large detection equipment being rarely used. This is because large detection equipment would be unstable if positioned solely by astronauts stepping on it. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the present invention provides a spiral drilling retractable anchoring device and detection equipment for extraterrestrial environments.

[0004] The technical solution of this invention to solve the above-mentioned technical problems is as follows: This invention provides a spiral drilling and retraction anchoring device for extraterrestrial environments, including an anchor head rod, a tie rod, an anchor body rod, an anchor plate assembly, and an anchoring cloth. The anchor head rod includes an anchor head section and an anchor rod section that are axially fixedly connected. The lower end of the anchor rod section is fixedly connected to the upper end of the anchor head section. The cross-section of the anchor rod section is a polygonal structure. The anchor body rod is a hollow structure and is slidably sleeved on the anchor rod section. A threaded connection groove is formed inside the anchor rod section. The threaded connection groove is coaxially arranged with the anchor rod section, and the groove opening is located on the upper end face of the anchor rod section. The tie rod is coaxially sleeved inside the anchor body rod. The lower part of the tie rod is threadedly connected to the threaded connection groove, and the upper end of the tie rod is rotatably connected to the upper end of the anchor body rod. Multiple sets of anchor plates are hinged between the lower end of the anchor rod and the upper end of the anchor head section. An anchoring cloth is connected between adjacent sets of anchor plates. When the multiple sets of anchor plates are retracted, they form a hollow cylindrical structure. The pull rod rotates, driving the anchor head rod to move axially relative to the pull rod and the anchor rod, thereby causing the anchor plate sets to extend and retract.

[0005] The beneficial effects of this invention are as follows: The spiral drilling and retractable anchoring device for extraterrestrial environments of this invention, by setting up an upper anchor plate and a lower anchor plate that are hinged to each other, can be closed and unfolded. When closed, it occupies very little volume and space due to the action of the tie rod. When drilling into soft extraterrestrial soil, the unfolded anchor plate assembly provides strong anchoring capacity, providing a stable mechanical foundation for the anchored equipment. Since spacesuits limit the minimum operating height for astronauts to 900mm above the surface of an extraterrestrial planet, this invention can meet the operational needs of astronauts by designing the length of the anchor rod.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the anchor plate assembly includes an upper anchor plate and a lower anchor plate. The lower end of the upper anchor plate is hinged to the upper end of the lower anchor plate via a first hinge shaft. The upper end of the upper anchor plate is hinged to the lower end of the anchor rod via a second hinge shaft. The lower end of the lower anchor plate is hinged to the upper end of the anchor head section via a third hinge shaft. The first hinge shaft, the second hinge shaft, and the third hinge shaft are arranged in parallel.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by setting two mutually hinged anchor plates, it is convenient for the anchor plate assembly to be unfolded and retracted under the action of the tie rod.

[0009] Furthermore, the lower end of the anchor rod is provided with multiple first ear plates, and the upper end of the anchor head section is provided with multiple second ear plates. The multiple first ear plates and the multiple second ear plates are arranged in a one-to-one correspondence, and the anchor plate group is hinged to the first ear plates and the second ear plates respectively.

[0010] The beneficial effect of adopting the above-mentioned further solution is that by setting the first ear plate and the second ear plate, the hinged installation of the anchor plate assembly is facilitated.

[0011] Furthermore, a set of anchor plates is provided on each outer side of the anchor bolt segment.

[0012] The beneficial effect of adopting the above-mentioned further solutions is that it makes the overall anchoring structure more stable and reliable.

[0013] Furthermore, the cross-section of the anchor bolt segment is a square structure.

[0014] Furthermore, the outer diameter of the hollow cylindrical structure formed by the multiple sets of anchor plates after being gathered together is the same as the outer diameter of the anchor rod.

[0015] Furthermore, the outer wall of the hollow cylindrical structure is provided with a first external thread, the outer wall of the anchor rod is provided with a second external thread, and the outer wall of the anchor head section is provided with a third external thread.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that by setting external threads, it is possible to achieve spiral drilling into the surface of extraterrestrial bodies.

[0017] Furthermore, the anchor head section has a conical structure, and the upper circumference of the anchor head section extends beyond the circumference of the anchor rod section by a predetermined distance to form a hinge platform, and the anchor plate assembly is hinged to the hinge platform.

[0018] Furthermore, it also includes an anchor head cover, wherein the upper end of the tie rod contacts or is clearance-fitted with the upper inner wall of the anchor rod, the upper inner wall of the anchor rod forms an annular limiting boss, and the upper outer wall of the tie rod forms an annular limiting shoulder, the annular limiting shoulder being adapted to abut against the annular limiting boss, and the anchor head cover is fixed to the upper outer wall of the anchor rod and axially limits the upper end face of the tie rod.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting an annular limiting boss and an annular limiting shoulder, the axial limiting fit between the tie rod and the anchor rod is facilitated, so that the tie rod can only rotate circumferentially relative to the anchor rod and will not move axially.

[0020] The present invention also provides a detection device, including a spiral drilling and retraction anchoring device for extraterrestrial environments as described above, and a detection device body. A clamping head is fixed to the upper end of the anchor rod, and a limiting section is formed on the outer wall of the clamping head. The limiting section is a conical structure that is larger at the top and smaller at the bottom. An anchoring hole is provided on the detection device body, and the anchoring hole is a conical hole adapted to the limiting section. The spiral drilling and retraction anchoring device for extraterrestrial environments can pass through the anchoring hole and anchor into the extraterrestrial soil layer, and the limiting section limits the anchoring hole.

[0021] The beneficial effects of the present invention are: the detection device of the present invention can anchor the detection device body through a spiral drilling and retractable anchoring device in an extraterrestrial environment. When drilling into soft extraterrestrial soil in an extraterrestrial environment, the deployed anchor plate group can provide strong anchoring ability and provide a stable mechanical foundation for the detection device.

[0024] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0025] Example 1 like Figures 1-8 As shown in this embodiment, a spiral drilling and retraction anchoring device for an extraterrestrial environment includes an anchor head rod, a tie rod 2, an anchor body rod 3, an anchor plate assembly 4, and an anchoring cloth 5. The anchor head rod includes an anchor head section 1 and an anchor rod section 11 that are axially fixedly connected. The lower end of the anchor rod section 11 is fixedly connected to the upper end of the anchor head section 1. The cross-section of the anchor rod section 11 is a polygonal structure. The anchor body rod 3 is a hollow structure and is slidably sleeved on the anchor rod section 11. A threaded connection groove 12 is formed inside the anchor rod section 11. The threaded connection groove 12 is coaxially arranged with the anchor rod section 11 and the groove opening is located at... On the upper end face of the anchor rod section 11; the tie rod 2 is coaxially sleeved in the anchor body rod 3, the lower part of the tie rod 2 is threadedly connected in the threaded connection groove 12, and the upper end of the tie rod 2 is rotatably connected to the upper end of the anchor body rod 3; multiple sets of anchor plate groups 4 are hinged between the lower end of the anchor body rod 3 and the upper end of the anchor head section 1, and an anchoring cloth 5 is connected between two adjacent sets of anchor plate groups 4. After the multiple sets of anchor plate groups 4 are retracted, they form a hollow cylindrical structure; the tie rod 2 rotates, driving the anchor head rod to move axially relative to the tie rod 2 and the anchor body rod 3, thereby driving the anchor plate groups 4 to extend and retract.

[0026] like Figure 5 and Figure 6As shown, in a specific embodiment, the lower end of the anchor rod 3 is provided with multiple first ear plates 31, and the upper end of the anchor head section 1 is provided with multiple second ear plates 13. The multiple first ear plates 31 and the multiple second ear plates 13 are arranged in a one-to-one correspondence. The anchor plate assembly 4 is hinged to the first ear plates 31 and the second ear plates 13 respectively. By setting the first ear plates and the second ear plates, the hinged installation of the anchor plate assembly is convenient.

[0027] like Figures 1-6 As shown, preferably, each outer side of the anchor bolt segment 11 is provided with a set of anchor plates 4, making the overall anchoring structure more stable and reliable.

[0028] Optionally, the cross-section of the anchor section 11 is a square structure.

[0029] Specifically, in this embodiment, the outer diameter of the hollow cylindrical structure formed by the multiple sets of anchor plates 4 after being gathered together is the same as the outer diameter of the anchor rod 3.

[0030] like Figures 1-6 As shown, specifically, the outer wall of the hollow cylindrical structure is provided with a first external thread 46, the outer wall of the anchor rod 3 is provided with a second external thread 32, and the outer wall of the anchor head section 1 is provided with a third external thread 14. By setting external threads, spiral drilling into the surface of extraterrestrial bodies can be achieved.

[0031] like Figure 1 and Figure 5 As shown, specifically, the anchor head section 1 has a conical structure, and the upper circumference of the anchor head section 1 extends beyond the circumference of the anchor rod section 11 by a predetermined distance to form a hinge platform 15, and the anchor plate group 4 is hinged to the hinge platform 15.

[0032] In this embodiment of the auger drilling and retractable anchoring device for extraterrestrial environments, rotating the tie rod 2 causes it to rotate relative to the anchor rod 3. The tie rod 2 drives the anchor rod section 11 to move axially, causing the anchor plate assembly 4 between the anchor rod 3 and the anchor head section 1 to unfold outwards under pressure. When the auger drilling and retractable anchoring device moves upwards, the anchor plate assembly closes to form a cylindrical structure with the same shape as the anchor rod 3, and the anchoring cloth is also stored inside. This auger drilling and retractable anchoring device for extraterrestrial environments is generally not recycled after use.

[0033] The spiral drilling and retractable anchoring device in this embodiment, when closed by the action of the tie rod, occupies very little volume and space. When drilled into the soft soil in the underground environment, the unfolded anchor plate assembly can provide strong anchoring ability and provide a stable mechanical foundation for the anchored equipment.

[0034] Example 2 Based on Embodiment 1, this embodiment provides a preferred structure for an anchor plate assembly, such as... Figure 1 and Figure 2 As shown, the anchor plate assembly 4 includes an upper anchor plate 41 and a lower anchor plate 42. The lower end of the upper anchor plate 41 is hinged to the upper end of the lower anchor plate 42 via a first hinge shaft 43. The upper end of the upper anchor plate 41 is hinged to the lower end of the anchor rod 3 via a second hinge shaft 44. The lower end of the lower anchor plate 42 is hinged to the upper end of the anchor head section 1 via a third hinge shaft 45. The first hinge shaft 43, the second hinge shaft 44, and the third hinge shaft 45 are arranged in parallel. By providing two mutually hinged anchor plates, the anchor plate assembly can be easily deployed and retracted under the action of the tie rod.

[0035] In this embodiment, when the spiral drilling and retractable anchoring device is used in an extraterrestrial environment, the pull rod 2 is rotated so that the pull rod 2 rotates relative to the anchor rod 3. The pull rod 2 drives the anchor rod section 11 to move axially. The upper anchor plate and the lower anchor plate between the anchor rod 3 and the anchor head section 1 are compressed and unfold outward, which at the same time drives the anchoring cloth between the anchor plates to open.

[0036] The spiral drilling and retractable anchoring device in this embodiment features an upper and lower anchor plate that are hinged together. The upper and lower anchor plates can be closed and opened. After being closed by the action of the tie rod, the device occupies very little volume and space. When drilling into soft soil in an outdoor environment, the opened anchor plate assembly can provide strong anchoring ability and provide a stable mechanical foundation for the anchored equipment.

[0037] Example 3 Based on Embodiment 1 or Embodiment 2, the auger drilling and retraction anchoring device in this embodiment for extraterrestrial environments further includes an anchor head cover 6, such as... Figure 7 and Figure 8As shown, the upper end of the pull rod 2 contacts or is clearance-fitted with the inner sidewall of the upper end of the anchor rod 3. The pull rod 2 can rotate relative to the inner sidewall of the anchor rod 3, and when the pull rod 2 moves downward, it can also drive the anchor rod 3 downward. An annular limiting boss 33 is formed on the inner sidewall of the upper end of the anchor rod 3, and an annular limiting shoulder 21 is formed on the outer sidewall of the upper end of the pull rod 2. The annular limiting shoulder 21 fits against the annular limiting boss 33, and the annular limiting shoulder 21 and the annular limiting boss 33 cooperate with each other, so that the pull rod drives the anchor rod 3 to move axially downward. The anchor head cover 6 is fixed to the outer sidewall of the upper end of the anchor rod 3 and axially limits the upper end face of the pull rod 2. The upper end faces of the anchor rod 3 and the pull rod 2 are flush. The anchor head cover 6 has a cylindrical structure, and an annular limiting pressure plate 63 is formed on the inner side wall of the anchor head cover 6. The anchor head cover 6 is pressed against the upper end face of the anchor rod 3 and the tie rod 2 through the annular limiting pressure plate 63. By setting the annular limiting boss and the annular limiting shoulder, the axial limiting fit between the tie rod and the anchor rod is facilitated, so that the tie rod can only rotate circumferentially relative to the anchor rod and will not move axially.

[0038] Example 4 This embodiment provides a detection device, including a spiral drilling and recovery anchoring device for extraterrestrial environments as described in any of the above embodiments, and also includes a detection device body 200, as shown in the example. Figure 9 and Figure 10 As shown, a clamping head 61 is fixed to the upper end of the anchor rod 3. The outer wall of the clamping head 61 forms a limiting section 62, which is a conical structure that is larger at the top and smaller at the bottom. An anchoring hole 201 is provided on the detection device body 200. The anchoring hole 201 is a conical hole adapted to the limiting section. The spiral drilling and retractable anchoring device in the extraterrestrial environment can pass through the anchoring hole and anchor into the extraterrestrial soil layer, and limit the anchoring hole through the limiting section. The detection device of this embodiment can anchor the detection device body through the spiral drilling and retractable anchoring device in the extraterrestrial environment. When drilling into the soft extraterrestrial soil, the deployed anchor plate assembly can provide strong anchoring ability and provide a stable mechanical foundation for the detection device.
