Description

Technical Field

[0001] This invention relates to the field of anchoring technology, specifically to a rope-driven, plant root sheath-inspired anchoring mechanism. Background Technology

[0002] Asteroids, as important remnants of the early formation and evolution of the solar system, contain abundant mineral resources. Their exploration is of paramount value and significance for revealing the origins of life and for resource exploration. In recent years, asteroid exploration has become a research hotspot internationally. However, asteroids have extremely low gravitational pull, mostly around 10... -3 -10 -5 G-class asteroids experience negligible gravity and escape velocities as low as 20 cm / s. During landing, the lander's thrust, the sampling mechanism's reaction force, and the radiation and magnetic forces in space can all push the asteroid away from its surface. Therefore, designing a suitable anchoring device to ensure the lander can remain stably on the asteroid surface for an extended period is one of the key technologies for asteroid exploration.

[0003] Currently, existing anchoring technologies have many shortcomings and deficiencies in asteroid exploration. On the one hand, the extreme environment, unknown geological features, and limited carrying capacity of landers on asteroid surfaces pose significant challenges to lander anchoring. Traditional anchoring devices often struggle to adapt to the complex terrain and geological conditions of asteroid surfaces, easily leading to problems such as insecure anchoring and structural damage. On the other hand, existing anchoring technologies have limitations in their transmission methods. For example, belt drives and chain drives may suffer from problems such as transmission jamming, excessive friction, and severe wear, making it difficult to meet the requirements of efficient and reliable transmission for anchoring devices in asteroid exploration missions.

[0004] In summary, existing asteroid probe anchoring technologies have significant shortcomings in adapting to complex environments and achieving efficient transmission, making it difficult to meet the needs of asteroid exploration missions. Therefore, there is an urgent need for a novel anchoring mechanism that can draw inspiration from the biomimetic structure of plant root sheaths and combine the advantages of rope-driven methods to achieve efficient and reliable anchoring, thereby improving the stability and reliability of asteroid probes on asteroid surfaces.

[0006] To address the shortcomings of existing technologies, this invention provides a rope-driven, plant-root sheath-like anchoring mechanism to solve the problems of traditional anchoring devices in the background technology, which are often unable to adapt to the complex terrain and geological conditions on the surface of asteroids, and are prone to unstable anchoring and structural damage.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a rope-driven, plant root sheath-like anchoring mechanism, comprising:

[0009] Hollow anchoring drill bit;

[0010] A root sheath anchoring assembly is disposed inside the anchoring drill bit. The root sheath anchoring assembly includes two flexible drill rods, one end of which extends to the outside of the anchoring drill bit, for reinforcing the anchoring drill bit to the planetary ground.

[0011] A drive assembly is disposed inside the anchoring drill bit. The drive assembly includes two protrusion units for protruding two flexible drill rods and a rope drive unit for driving the two protrusion units.

[0012] Preferably, the anchoring drill bit has an internally fixedly connected storage frame for storing the flexible drill rod, and the storage frame has an internal partition plate;

[0013] The bottom of the storage frame is fixedly connected to two guide tubes, the bottom ends of which extend to the outside of the anchoring drill bit, and the two flexible drill rods protrude through the two guide tubes respectively.

[0014] Preferably, several sets of drill barbs are fixedly connected to the outer surfaces of both flexible drill rods;

[0015] Several sets of drill rod barbs are made of shape memory alloy.

[0016] Preferably, the rope drive unit includes two loop ropes, two upper transition pulleys, two lower transition pulleys, two drive wheels, and a transmission component for driving the two loop ropes.

[0017] Two drive wheels are used to drive two protrusion units through their own rotation, which in turn protrude the flexible drill rod inside the guide tube.

[0018] Preferably, the transmission component includes a protective cover fixed inside the anchoring drill bit, and two transmission wheels are rotatably connected inside the protective cover, and the two transmission wheels are connected by meshing gears.

[0019] The protective cover has a motor fixedly connected inside for driving the rotation of one of the drive wheels.

[0020] Preferably, the outer surface of the guide tube has two groove notches;

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the present invention provides a rope-driven plant root sheath anchoring mechanism, which has the following beneficial effects:

[0029] This invention draws inspiration from the structural characteristics of plant root sheaths and uses a flexible drill rod as an anchoring component. When extended, it can penetrate deep into the planetary surface like plant roots. Furthermore, the barbs on the drill rod surface pop out and unfold after extension, further enhancing the anchoring force. The biomimetic design allows it to better adapt to the complex terrain and geological conditions of the asteroid surface, greatly improving the stability and reliability of the anchoring and effectively solving the problem of weak anchoring that is common with traditional anchoring devices on asteroid surfaces.

[0030] This invention employs a rope-driven unit to propel the flexible drill rod out. Compared to traditional belt drives and chain drives, rope drives offer advantages such as higher transmission power or torque and greater flexibility. The rope's resilience helps prevent transmission jamming to some extent. Furthermore, by incorporating a transition pulley mechanism, the rope's angle during transmission is ensured to be appropriate, avoiding wear or jamming caused by excessive rope angles and increased friction due to limited space. This improves the reliability and stability of the drive system, better meeting the requirements for efficient and reliable transmission of anchoring devices in asteroid exploration missions.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1:

[0047] See attached document Figures 1 to 8 A rope-driven, plant root sheath-like anchoring mechanism, comprising:

[0048] Hollow anchoring drill bit 100;

[0049] The root sheath anchoring assembly 200 is disposed inside the anchoring drill bit 100. The root sheath anchoring assembly 200 includes two flexible drill rods 201, and one end of each of the two flexible drill rods 201 extends to the outside of the anchoring drill bit 100 for reinforcing the anchoring of the anchoring drill bit 100 to the planetary ground.

[0050] The root sheath anchoring component 200 is a plant root sheath type, made of flexible material, which is convenient to store inside the anchoring drill bit 100 and extend freely. The drill rod mechanism is equipped with barbs, which pop out when the drill bit is deep, increasing the anchoring force. Since the application scenario is mainly asteroid debris landing, this invention adopts biomimicry and draws on the good anchoring force of plant root sheaths.

[0051] The drive assembly 300 is disposed inside the anchoring drill bit 100. The drive assembly 300 includes two protrusion units 310 for protruding two flexible drill rods 201 and a rope drive unit 320 for driving the two protrusion units 310.

[0052] The two protruding units 310 can be driven by the rope drive unit 320 in the drive assembly 300, so that the two protruding units 310 can be driven synchronously and independently, thereby protruding the two flexible drill rods 201 in the root sheath anchoring assembly 200 from the inside of the anchoring drill bit 100 to form root sheath anchoring.

[0053] It should be noted that the rope drive unit 320 adopts a rope drive form, which meets the requirements for the force or torque required for transmission. Compared with belt drive and chain drive, it is more flexible, and the toughness of the rope also prevents transmission jamming to a certain extent. In addition, the rope drive unit 320 incorporates a transition pulley mechanism to ensure that the angle of the rope is appropriate during transmission, avoiding excessive rope angle due to limited space, which would increase friction and cause wear or jamming.

[0054] As a clever structure in nature, the root sheath is a key root shape that improves the utilization of water and nutrients by plants through a variety of mechanisms. It can provide sufficient anchoring torque for plants to take root and fix them in the soil.

[0055] Meanwhile, the flexibility of the root system allows it to grow and take root in hard environments such as rocks and rubble piles without being structurally damaged. The interaction between the plant root sheath and the soil provides important biomimetic inspiration for the design of asteroid probe anchoring devices.

[0056] Rope-driven methods offer advantages such as high power or torque transmission and high flexibility, effectively overcoming the shortcomings of traditional transmission methods and providing new ideas for the design of drive methods for anchoring mechanisms.

[0057] See attached document Figures 2-5The anchoring drill bit 100 has a storage frame 202 for storing the flexible drill rod 201, and a partition plate is provided inside the storage frame 202. The storage frame 202 is used to store the flexible drill rod 201 in the root sheath anchoring assembly 200, and the partition plate is used to separate the two flexible drill rods 201 to prevent them from interfering with each other.

[0058] The bottom of the storage frame 202 is fixedly connected to two guide tubes 203. The bottom ends of the two guide tubes 203 extend to the outside of the anchoring drill bit 100, and the two flexible drill rods 201 protrude through the two guide tubes 203 respectively.

[0059] The two guide tubes 203 are used to guide the two flexible drill rods 201 inside the storage frame 202, so that the two flexible drill rods 201 can better protrude from the inside of the storage frame 202 to form a root sheath anchoring operation.

[0060] See attached document Figure 2 and Figure 4 Several sets of drill barbs 204 are fixedly connected to the outer surfaces of the two flexible drill rods 201. The several sets of drill barbs 204 are made of shape memory alloy, which makes it easy for the drill barbs 204 to be initially retracted to the surface of the flexible drill rod 201. When the barbs extend out of the hole, the shape memory alloy is unrestrained and pops out one by one, becoming an unfolded state, thus completing the anchoring function.

[0061] The flexible drill rod 201 moves inside the guide tube 203, which not only makes it easier to limit the protrusion trajectory of the flexible drill rod 201 through the guide tube 203 and improve the smoothness of its protrusion, but also allows the drill rod barbs 204 on the outer surface of the flexible drill rod 201 to be contracted and limited.

[0062] See attached document Figure 2 , Figure 4 and Figure 5 The rope drive unit 320 includes two loop ropes 321, two upper transition pulleys 322, two lower transition pulleys 323, two drive wheels 324, and a transmission component for driving the two loop ropes 321.

[0063] Two loop ropes 321 are respectively wound and connected to the outer surfaces of two upper transition pulleys 322, two lower transition pulleys 323, and two drive wheels 324, and the loop ropes 321 are wound at least one turn when they are wound and connected; the two loop ropes 321 are driven to rotate by the transmission component to make the two drive wheels 324 rotate, thus forming the driving operation of the two protruding units 310.

[0064] It should be noted here that the upper transition pulley 322 and the lower transition pulley 323 are designed to ensure that the angle formed between the ring rope 321 and the transmission component and the drive wheel 324 is appropriate, so as to avoid excessive rope angle due to limited space, which would increase friction and cause wear or jamming.

[0065] Two drive wheels 324 are used to drive two protruding units 310 by their own rotation, and the flexible drill rod 201 inside the guide tube 203 is protruded through the two protruding units 310.

[0066] The two drive wheels 324 are respectively connected to the two probing units 310, so that the two probing units 310 can be directly driven by the rotation of the two drive wheels 324, so that the two probing units 310 can automatically probing the two flexible drill rods 201.

[0067] See attached document Figure 4 and Figure 5 The transmission component includes a protective cover 325 fixed inside the anchoring drill bit 100. Two transmission wheels 326 are rotatably connected inside the protective cover 325, and the two transmission wheels 326 are connected by a gear 327 that meshes with each other. Two annular ropes 321 are respectively wound and connected to the outer surfaces of the two transmission wheels 326.

[0068] The two drive wheels 326 are connected by meshing gears 327, so that when one drive wheel 326 rotates, it can drive the other drive wheel 326 to rotate synchronously, forming a synchronous and symmetrical rotation of the two drive wheels 326, thereby ensuring that the two protruding units 310 are driven synchronously.

[0069] Here, the two loop ropes 321 are respectively wound and connected to the outer surfaces of the two transmission wheels 326. When the loop ropes 321 are wound and connected, they are wound at least once to ensure that the transmission wheels 326 can better circulate the loop ropes 321, thereby forming the rotation drive of the drive wheel 324.

[0070] The protective cover 325 has a motor fixedly connected inside for driving the rotation of one of the drive wheels 326;

[0071] The motor is connected to the external control system and is a reversible motor. It is set up using existing connection and coding methods to drive one of the transmission wheels 326 to rotate.

[0072] See attached document Figure 6 and Figure 7 Two grooves 205 are provided on the outer surface of the guide tube 203;

[0073] By setting two grooves and notches 205, it is convenient for the protruding end of the subsequent protruding unit 310 to directly contact the flexible drill rod 201 inside the guide tube 203, thus forming the protrusion work of the flexible drill rod 201.

[0074] It should be noted here that the two grooves 205 are created, and the flexible drill rod 201 is exposed, as shown in the following details. Figure 7 As shown, this ensures that when the probe end of the probe unit 310 comes into contact with the flexible drill rod 201, it will not come into contact with the guide tube 203.

[0075] The probe unit 310 includes two clamping plates 312 for clamping the flexible drill rod 201, which are slidably connected to the guide rod assembly 311.

[0076] Two clamping plates 312 are slidably connected on the guide assembly 311. By setting the two clamping plates 312, the flexible drill rod 201 inside the guide tube 203 can be clamped through the groove notch 205.

[0077] Both sides of the drive wheel 324 are fixedly connected to a cam 314 for moving the two clamping plates 312 up and down;

[0078] By fixing cams 314 to both sides of the drive wheel 324, the drive wheel 324 can directly drive the cams 314 to rotate synchronously. The rotation of the cams 314 can move the two clamping plates 312 along the diameter of the guide tube 203, thus forming the extension of the flexible drill rod 201.

[0079] Example 2: The difference from Example 1 is that;

[0080] See attached document Figure 6 and Figure 8 The outer surface of the cam 314 is provided with at least one protrusion, and the radius of the annular ring A of the protrusion is greater than the straight-line distance of the clamping plate 312 closest to the drive wheel 324.

[0081] By providing at least one protrusion on the outer surface of the cam 314, it is convenient to drive the clamping plate 312 downward through the protrusion, thereby forming the protrusion operation of the flexible drill rod 201. Moreover, by increasing the number of protrusions, the protrusion driving operation of the flexible drill rod 201 at different frequencies can be formed.

[0082] In this embodiment, the radius of the annular ring A of the protrusion is larger than the straight-line distance of the clamping plate 312 closest to the drive wheel 324. This facilitates the rotation of the protrusion by the cam 314. During the annular motion, the protrusion not only exerts a downward thrust on the clamping plate 312, enabling the flexible drill rod 201 to extend out, but also exerts a lateral thrust on the clamping plate 312, causing the clamping plate 312 to move towards the guide tube 203, thus enabling the flexible drill rod 201 to self-clamp. This provides a linkage function for clamping and extending the flexible drill rod 201.

[0083] A force-bearing block 316 is fixedly connected to the outer side of the clamping plate 312 closest to the drive wheel 324;

[0084] By setting the force block 316, the protrusion on the cam 314 on the drive wheel 324 can be driven, so that the force block 316 moves downward, thereby driving the flexible drill rod 201 held by the two clamping plates 312 to move downward, forming the extension work of the flexible drill rod 201.

[0085] Each of the two clamping plates 312 has a clamping protrusion fixedly connected to one side of its opposite side for clamping the flexible drill rod 201;

[0086] By providing clamping protrusions on the inner sides of the two clamping plates 312, it is convenient that when the two clamping plates 312 move in opposite directions, the exposed flexible drill rod 201 can be clamped through the groove notch 205 by the clamping protrusions.

[0087] A spring assembly is fixedly connected between the two clamping plates 312, and two V-shaped hinge brackets 315 are hinged between the two clamping plates 312.

[0088] By fixing a spring assembly between the two clamping plates 312, the two clamping plates 312 can be squeezed by the elastic force of the spring assembly itself, so that the two clamping plates 312 can be unfolded when they are not subjected to other pressure; thus, when the two clamping plates 312 move downward, they can be reset in a non-contact state when they are reset upward.

[0089] In this embodiment, by providing a V-shaped hinge frame 315 between the two clamping plates 312, it is convenient that when one clamping plate 312 moves toward the guide tube 203, the other clamping plate 312 moves synchronously toward the guide tube 203. This allows the two clamping blocks to clamp the flexible drill rod 201 through the groove notch 205. With the downward movement of the two clamping plates 312, the clamped flexible drill rod 201 can move downward, thus forming the extension operation of the flexible drill rod 201.

[0090] It should be noted here that the V-shaped hinge frame 315 consists of two symmetrically inclined hinge frames. One end of the two hinge frames is hinged to each other, and the other end is hinged to the two clamping plates 312 respectively.

[0091] The guide rod assembly 311 consists of several guide rods, and each of the several guide rods has a limiting protrusion at both ends for limiting the clamping plate 312.

[0092] In this embodiment, the guide rod assembly 311 is fixed inside the anchoring drill bit 100 by the elastic telescopic rod 313, and the telescopic trajectory of the elastic telescopic rod 313 is parallel to the guide tube 203, which facilitates the two clamping plates 312 connected to the guide rod assembly 311 to telescopically move along the pipeline direction of the guide tube 203, thereby facilitating the flexible drill rod 201 clamped by the two clamping plates 312 to extend.

[0093] Example 3: The difference from Example 1 is that;

[0094] See attached document Figure 1 and Figure 3 The anchoring drill bit 100 is internally provided with an adjustment component 400 for adjusting the protrusion angle of the two flexible drill rods 201;

[0095] The adjustment assembly 400 includes two spheres 401 movably connected to the outer surface of the bottom of the anchoring drill bit 100, and two guide tubes 203 extend through the two spheres 401 to the outside of the anchoring drill bit 100, and the two guide tubes 203 are fixedly connected to the inside of the two spheres 401 respectively.

[0096] By rolling the two balls 401 in the adjustment assembly 400 on the housing of the anchoring drill bit 100, the angle of the guide port of the guide tube 203 can be adjusted, thereby changing the protrusion angle of the flexible drill rod 201, and thus realizing root sheath anchoring work at different angles.

[0097] Each guide tube 203 includes an upper tube body connected to the storage frame 202 and a lower tube body connected to the ball 401, and the upper tube body and the lower tube body are connected by a movable sleeve.

[0098] The guide tube 203 is composed of an upper tube body and a lower tube body, and the upper tube body and the lower tube body are connected by a movable sleeve to ensure that the upper part of the guide tube 203 guides the flexible drill rod 201 to extend, and also ensures the smoothness of the extension angle adjustment of the guide tube 203.

[0099] An adjusting cylinder 402 is fixedly connected to the inner bottom of the anchoring drill bit 100, and an H-shaped block 403 is fixedly connected to the telescopic end of the adjusting cylinder 402. Movable shafts 404 are fixedly connected to both sides of the H-shaped block 403. Movable sleeves 405 are fixedly connected to the outer surfaces of the two spheres 401. The two movable sleeves 405 are respectively movably sleeved on the outer surfaces of the two movable shafts 404.

[0100] By having two movable sleeves 405 respectively movably fitted onto the outer surfaces of two movable shafts 404, the H-shaped block 403 can move up and down, and the two movable shafts 404 can move the two movable sleeves 405, causing the ball 401 to roll in the installation position, ultimately forming the angle adjustment work of the lower part of the guide tube 203, and finally realizing the root sheath anchoring work at different angles.

[0101] It should be noted here that the adjusting cylinder 402 is used to move the H-shaped block 403 up and down, thereby adjusting the protrusion angle of the flexible drill rod 201.

[0102] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
