Abstract

A lunar surface cable and self-burying method based on active electron beam energization and electrostatic repulsion are disclosed, relating to the fields of lunar engineering and deep space exploration. Addressing the problems of existing technologies where lunar surface cables are susceptible to lunar dust abrasion and radiation damage, and where mechanical burying methods are energy-intensive, inefficient, and have poor adaptability, this invention proposes a technical solution for autonomous cable settlement and burial without mechanical excavation. This solution involves setting up a chargeable outer shell and an electron beam emitting mechanism. First, a positive charge is applied to the cable surface to repel lunar dust. Then, an electron beam is emitted into the lunar soil beneath the cable, causing it to become negatively charged. Subsequently, the surface charge of the cable is switched to negative to create a repulsive effect, thereby forming a cavity beneath the cable and driving it to settle under lunar gravity, ultimately achieving natural backfilling and burial with lunar soil. This invention is applicable to scenarios such as lunar base construction and energy and communication network deployment, and can significantly improve cable protection capabilities and laying efficiency.

Description

Technical Field

[0001] This relates to the fields of lunar engineering and deep space exploration technology, specifically to a lunar surface cable based on active electron beam empowerment and electrostatic repulsion, and its self-burying method. Background Technology

[0002] As lunar exploration missions shift from short-term scientific exploration to long-term stays and base construction, lunar infrastructure construction has gradually become a research focus. Among these, power and communication cables, as key carriers connecting various functional modules, have received widespread attention for their safety and reliability. Current technologies addressing lunar cable protection primarily focus on material reinforcement, protective structure design, and optimized laying methods. For example, using more wear-resistant polymer insulation materials or composite sheath structures can improve the cable's resistance to lunar dust abrasion; adding outer protective coatings or multi-layered sheathing structures can mitigate the effects of cosmic radiation and temperature cycling on the cable; additionally, some technologies attempt to partially shield the cable by setting up cable trenches, protective conduits, or covering it with protective panels, thereby reducing its exposure. Regarding cable laying, some studies propose using lunar robots or automated equipment for shallow burial, or using mechanical excavation devices to achieve cable burial, in order to improve its environmental adaptability.

[0003] However, most of the existing technical solutions rely on passive protection or mechanical means, which still have significant limitations in the low gravity, high vacuum, and strong electrostatic environment of the moon. On the one hand, simply relying on material or structural reinforcement is insufficient to fundamentally solve the problems of high lunar dust adhesion and continuous abrasion, and cannot effectively cope with micrometeorite impacts and long-term radiation damage. On the other hand, mechanical excavation or burial methods usually require complex equipment support, resulting in high energy consumption, large weight, complex operation, and significant disturbance to the lunar regolith, which is not conducive to large-scale deployment and long-term operation. In addition, existing technologies generally lack the active utilization of the electrical properties of the lunar regolith, and fail to achieve autonomous cable settling and burial by controlling the charge relationship between the cable and the lunar regolith. Therefore, how to achieve efficient, autonomous, and low-energy burial of cables in the lunar environment without relying on large mechanical equipment, while taking into account adaptability and controllability under different lunar regolith conditions, has become an urgent technical problem to be solved.

[0004] In summary, existing technologies have several drawbacks, including difficulty in achieving autonomous cable burial under low energy consumption and lightweight conditions, insufficient utilization of lunar soil electrical properties, poor controllability of the burial process, and insufficient adaptability to the complex lunar environment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, such as difficulty in achieving autonomous cable burial under low-energy consumption and lightweight conditions, insufficient utilization of lunar soil electrical properties, poor controllability of the burial process, and insufficient adaptability to the complex lunar environment, the technical solution provided by this invention is as follows: A lunar cable based on active electron beam energization and electrostatic repulsion, comprising: The cable comprises a core conductive cable core, an inner insulation layer, an electron beam emitting mechanism, a surface chargeable outer shell, and a permeable outer covering, arranged coaxially from the inside to the outside in a radial direction. The core conductive cable is used to transmit power or communication signals and is electrically connected to a power management and control unit. The inner insulation layer is a continuous annular structure covering the outside of the core conductive cable core, used for electrical isolation and environmental protection. The electron beam emitting mechanism is located outside the inner insulation layer and distributed along the circumference of the cable, arranged in a fan-shaped array at the bottom and lower sides of the cable's radial cross-section, used to directionally emit electron beams to the external medium below and to the sides of the cable. The surface chargeable outer shell is a continuous annular conductive structure covering the outside of the electron beam emitting mechanism. The structure is electrically connected to the power management and control unit, and is used to be selectively charged with positive or negative charges at different operating stages to generate electrostatic effects; the permeable outer layer is disposed on the outermost side and forms a mesh, fiber, or porous structure to allow external particulate media to permeate without hindering electron beam propagation; wherein, the power management and control unit is configured to control the electron beam emitting mechanism to emit an electron beam into the area below the cable to make the external particulate media negatively charged, and to control the charge polarity of the surface chargeable outer shell to switch between positive and negative charges, so as to form a staged electrostatic repulsion between the cable and the external particulate media, thereby forming a cavity below the cable and realizing the cable's autonomous settling structure.

[0006] Furthermore, in a preferred embodiment, the electron beam emitting mechanism includes a plurality of micro-electron emitting units, each of which includes an emitting electrode, an accelerating electrode, and a guiding structure, and the plurality of micro-electron emitting units are distributed along the circumference of the cable and form a directional emitting array in the bottom and lower side regions of the radial cross section.

[0007] Furthermore, in a preferred embodiment, the surface chargeable shell is made of conductive polymer material, metallized fabric material or carbon nanomaterial, and is electrically connected to the power management and control unit via conductive connections.

[0008] Furthermore, in a preferred embodiment, the permeable outer layer is coated with a mesh structure, a fibrous structure, or a porous structure, the pore size of which is configured to allow lunar soil particles to enter or attach.

[0009] Furthermore, in a preferred embodiment, the inner insulation layer is made of an insulating material that is resistant to radiation and high and low temperature cycling.

[0010] Furthermore, in a preferred embodiment, the power management and control unit draws power from the core conductor cable core or is powered by an independent power supply module.

[0011] Based on the same inventive concept, this invention also provides a method for self-burying lunar cables based on active electron beam empowerment and electrostatic repulsion, implemented using the aforementioned cable, comprising: The steps of applying a positive charge to the surface chargeable outer shell of a lunar cable based on active electron beam empowerment and electrostatic repulsion to remove external particulate media and form a clean area; The steps of controlling the electron beam emitting mechanism of a lunar cable based on active electron beam empowerment and electrostatic repulsion to emit an electron beam into the region below the cable so as to give the external particulate medium a negative charge; The step of switching the charge on the surface of the lunar cable, which is based on active electron beam empowerment and electrostatic repulsion, to a negative charge so as to create a repulsive effect with the negatively charged particle medium below. The steps of forming a cavity below the cable under the repulsive force and causing the lunar cable based on active electron beam empowerment and electrostatic repulsion to sink downwards; The steps involved in continuously emitting an electron beam and maintaining a negative charge on the surface shell during the settling process to achieve continuous settling. The process involves stopping electron beam emission after reaching the predetermined depth and neutralizing the charge on the surface layer to allow the external particulate medium to naturally backfill and complete the burial.

[0012] Based on the same inventive concept, the present invention also provides a computer storage medium for storing a computer program, wherein when the computer program is read by a computer, the computer executes the method described thereon.

[0013] Based on the same inventive concept, the present invention also provides a computer, including a processor and a storage medium, wherein when the processor reads a computer program stored in the storage medium, the computer executes the method described thereon.

[0014] Based on the same inventive concept, the present invention also provides a computer program product, which, when executed, implements the method described.

[0015] Compared with the prior art, the advantages of the technical solution provided by the present invention are as follows: The core conductor cable core serves as the main carrier of power or communication signals, enabling the cable to achieve self-burial without affecting its basic function transmission capability. This effect comes from the core conductor cable core part in the cable structure. Compared with the existing technology that simply emphasizes the protective structure, this solution maintains functional continuity while achieving burial, avoiding the impact of additional structures on the stability of electrical performance.

[0016] The inner insulation layer provides electrical isolation and physical protection for the core conductor cable, improving safety and stability under charge regulation and electron beam effects. This effect originates from the inner insulation layer in the cable structure. Compared to ordinary insulation structures in existing technologies, this solution needs to adapt to high-voltage pulse and charge change environments, thus providing a higher guarantee for insulation stability.

[0017] The surface can be charged with positive and negative charges in a controllable manner to actively regulate lunar dust particles. This effect comes from the process of applying positive charges in the initial stage to repel lunar dust and then converting them into negative charges in the subsequent stage to participate in the repulsion. Compared with existing technologies that rely on passive protection or simple shielding, this solution can actively intervene in the adhesion behavior of lunar dust and reduce the risk of abrasion from the source.

[0018] The ability of the surface-mounted shell to switch charge polarity enables the cable to perform different functions at different stages. This effect comes from the charge switching process from positive to negative in the implementation, which allows the system to clean the surface before driving the settling. Compared with the single-function structure in the prior art, this solution achieves phased functional synergy, improving overall efficiency and reliability.

[0019] The electron beam emitting mechanism actively energizes the charge state of the lunar soil by emitting high-energy electron beams below and to the sides of the cable. This effect comes from the electron beam energizing stage in the implementation method. Compared with the existing technology, which does not actively modify the electrical properties of the lunar soil, this solution is the first to transform the lunar soil into an adjustable medium, providing basic conditions for subsequent sedimentation.

[0020] The directional arrangement of the electron beam emitting mechanism ensures that the electron beam primarily acts on the area below the cable, thereby avoiding adverse repulsion from the lunar dust above. This effect stems from the design of the electron beam being distributed in a fan-shaped array at the bottom and lower sides of the structure. Compared to existing non-directional control methods, this solution improves energy utilization efficiency and avoids disturbing irrelevant areas.

[0021] The power management and control module achieves controllable operation throughout the entire process by providing a high-voltage pulsed electric field and precisely regulating the amount and polarity of charge. This effect comes from the control process of electron beam emission and charge state switching in the implementation. Compared with the lack of precise control methods in the prior art, this solution can adjust the intensity of action according to lunar soil conditions and improve adaptability.

[0022] The permeable outer coating improves the stability of the sedimentation process by allowing lunar dust to permeate moderately and adhere stably without affecting electron beam and charge transfer. This effect comes from the mesh or porous outer layer design in the structure. Compared with a completely closed outer layer structure, this solution takes into account both particle interaction and functional realization.

[0023] The initial positive repulsion stage actively removes positively charged dust particles from the surrounding area by making the cable surface positively charged, thereby forming a clean area. This effect comes from the charge-giving process in the first stage of the implementation. Compared with the existing technology that relies on manual cleaning or passive protection, this solution achieves automatic cleaning and reduces initial wear.

[0024] The electron beam energizing stage continuously injects electrons into the subsurface lunar soil, making it negatively charged as a whole, thereby changing the interaction between lunar soil particles and between the lunar soil and the cable. This effect comes from the second stage of the implementation method. Compared with the existing technology that does not change the soil properties, this method reconstructs the action environment through electrical means.

[0025] The charge conversion and secondary repulsion stage creates a cavity beneath the cable by making the cable surface negatively charged, generating a strong repulsive force between it and the already negatively charged lunar soil. This effect comes from the charge switching and repulsion process in the third stage of the implementation method. Compared with the existing method of creating space by mechanical excavation, this solution can achieve structural change without physical cutting.

[0026] The cavity formation and autonomous settling mechanism eliminates the support below the cable, allowing the cable to sink naturally under the weak gravity of the moon. This effect comes from the process of forming a low-density area after repulsion in the implementation method. Compared with the existing technology that requires external force to press in or mechanical burial, this solution achieves contactless driven autonomous settling.

[0027] The self-reinforcing settling process formed by continuous empowerment and repulsion enables the cable to continuously advance downwards until it reaches the predetermined depth. This effect comes from the synergistic process of the continuous action of the electron beam and the negative charge retention of the cable in the implementation method. Compared with the existing one-time burial method, this solution has dynamic advancement capability and depth controllability.

[0028] The final charge neutralization and natural backfilling process of lunar soil restores the surrounding lunar soil to a stable state and forms a covering for the cable. This effect comes from the natural collapse process after the electron beam is stopped and the charge is neutralized in the implementation method. Compared with the existing technology that requires additional backfilling operations, this solution utilizes the environment itself to complete the burial, improving efficiency and reducing disturbance.

[0029] It is suitable for the automated laying and high-reliability protection of power and communication cables in lunar base construction and deep space exploration missions. Attached Figure Description

[0041] A computer program product is also provided, which, when executed, implements the method described.

[0042] Implementation Method Two, in conjunction with Appendix Figures 1-4 This embodiment is a further detailed description of the technical solution provided in Embodiment 1. Specifically: This embodiment provides a self-burying structure for lunar cables based on active electron beam empowerment and electrostatic repulsion, and its working method. The core of this structure is to achieve autonomous settling and burial of the cable in the lunar soil through layered structure design and charge regulation mechanism.

[0043] The cable adopts a layered composite structure constructed from the inside out, including a core conductor 5, an inner insulation layer 4, an electron beam emitting mechanism 3, a surface electric shell 2, and a permeable outer covering 1. The layers are coaxially arranged to form an integrated structure.

[0044] The core conductor 5 is located at the very center of the cable and is used to transmit power or communication signals. It can be a multi-strand conductor stranded structure or a single-core conductor structure, and the metal conductor material can be selected according to the usage requirements. The core conductor also serves as an internal power supply path, providing power support for the electron beam emitting mechanism 3 and the outer charge control.

[0045] The inner insulation layer 4 covers the outside of the core conductor cable core 5 and is used to provide electrical isolation and mechanical protection for the conductor cable core. The inner insulation layer is made of radiation-resistant and temperature difference-resistant insulating material to adapt to the extreme environment on the lunar surface and to ensure that no breakdown or leakage occurs during charge regulation.

[0046] The electron beam emitting mechanism 3 is located outside the inner insulation layer 4 and distributed along the circumference of the cable. It is preferably arranged in a fan-shaped array in the lower half and lower side area of ​​the cable cross-section. It includes multiple micro electron emitting units. Each emitting unit consists of an emitting electrode, an accelerating electrode and a guiding structure. It is used to emit high-energy electrons into the lunar soil below and to the side under the action of a control signal, thereby charging the lunar soil particles. The electron beam emitting mechanism is connected to the power management module through internal wires and can adjust the emission intensity, direction and duration according to the control command.

[0047] The surface-mountable outer shell 2 is disposed on the outside of the electron beam emitting mechanism 3. It is a functional layer that is conductive and controllably charged. The shell is made of conductive polymer material, metallized fiber material or carbon-based conductive material, and is connected to the control module through wires, so that it can be selectively charged with positive or negative electricity at different stages. The surface-mountable outer shell 2 continuously covers the circumference of the cable and forms a synergistic relationship with the electron beam emitting mechanism 3.

[0048] The permeable outer coating 1 is located on the outermost side. It has a mesh structure, fiber structure or porous structure, which allows lunar soil particles to enter or attach to a certain extent, while ensuring that the electron beam can penetrate and act on the external environment. This outer coating is used to stabilize the contact state between the cable and the surrounding lunar soil, and to enhance the structural stability after the lunar soil backfill is completed.

[0049] Based on the above structure, this embodiment also includes a power management and control unit, which is electrically connected to the core conductive cable core 5, the energized outer shell 2 of the surface layer and the electron beam emitting mechanism 3. It is used to provide a high-voltage electric field and regulate the charge polarity and electron beam emission process, thereby realizing the phased operation of the cable.

[0050] Based on the above structure, the self-burying process of this cable is as follows: After the cable is laid to the lunar surface, the control unit first makes the surface chargeable outer shell 2 positively charged, thereby repelling the positively charged lunar dust particles on the lunar surface, making the cable surface and its adjacent area a dust-free area, reducing particle adhesion and providing direct contact conditions for subsequent actions.

[0051] Subsequently, the control unit activates the electron beam emitting mechanism 3, which emits an electron beam into the lunar soil region below and to the side of the cable. The electrons enter the lunar soil particles and give them a negative charge, thereby changing the charge distribution of the lunar soil in that region.

[0052] After the lunar soil is given a negative charge, the control unit switches the charge on the surface chargeable outer shell 2 from positive to negative, so that the cable and the negatively charged lunar soil below will repel each other. This repulsion will act radially outward along the cable, thereby pushing away the lunar soil particles below and forming a low-density area or cavity structure at the bottom of the cable.

[0053] As the support weakens, the cable sinks downwards under the weak gravity of the moon. At the same time, the electron beam emitting mechanism continuously applies negative charge to the lunar soil in the newly contacted area and keeps the surface chargeable outer shell 2 in a negative charge state, so that the repulsive effect continues, thus forming a continuous sinking process.

[0054] Once the cable reaches the predetermined burial depth, the control unit stops emitting the electron beam and gradually neutralizes the charge on the surface chargeable outer shell 2. The repulsive effect between lunar soils disappears, and the surrounding lunar soils naturally backfill and cover the cable under the influence of gravity and structural disturbance, thus completing the self-burial process.

[0055] Through the coordinated design of the above structure and working method, the cable can automatically sink and be buried in the lunar environment without relying on mechanical excavation equipment, while having good adaptability, controllability and environmental friendliness.

[0056] Figure 2 The working state of the surface lunar dust cleaning stage is shown. In this stage, the outer surface of the cable is controlled to be positively charged. Since lunar dust particles are usually positively charged in the lunar environment, the positive charge on the cable surface and the surrounding lunar dust generate electrostatic repulsion, which pushes away the lunar dust particles attached to or close to the cable surface. This forms a relatively clean area around the cable, reduces particle adhesion and avoids initial abrasion, and provides a direct interface for subsequent charge action and electron beam transmission.

[0057] Figure 3The diagram illustrates the working state of the electron beam energizing stage. In this stage, the electron beam emitting mechanism inside the cable is activated and emits an electron beam directionally towards the lunar soil region below and to the side of the cable. Electrons enter the interior of the lunar soil particles and are adsorbed by them, causing the originally neutral or weakly charged lunar soil particles to acquire a negative charge. This forms a negatively charged subsurface region below the cable. The formation of this region changes the local charge distribution of the lunar soil, creating conditions for subsequent structural perturbation using charge repulsion.

[0058] Figure 4 The diagram illustrates the working state during the settling and backfilling stage. In this stage, the charge on the cable's surface can be switched to negative charge, creating a strong like-pole repulsion between the cable and the negatively charged lunar soil particles below. This pushes the lunar soil beneath the cable outward, forming a cavity structure. Under the weak gravity of the moon, the cable settles into this cavity. Simultaneously, as the electron beam continues to act, the settling process advances. Once the predetermined depth is reached, the electron beam emission stops, neutralizing the cable's charge. The surrounding lunar soil naturally backfills around the cable under the influence of gravity and disturbance, thus completing the burial and covering process of the cable.

[0059] Regarding electronic control: The steps involved in structurally integrating and constructing a cable to form a composite cable structure capable of charge modulation and electron beam interaction are as follows: First, the overall cable structure is constructed, with the core conductor placed at the center for transmitting power or communication signals. An inner insulation layer is coaxially wrapped around it to achieve electrical isolation and environmental protection. An electron beam emitting mechanism is integrated outside the inner insulation layer and arranged circumferentially along the cable, forming directional emission areas at the bottom and lower sides. A surface shell capable of carrying electricity is set outside the electron beam emitting mechanism, and the charge polarity can be controlled by conductive connection. A permeable outer layer is set on the outermost side to ensure that lunar soil particles can penetrate and adhere stably without affecting electron beam propagation. This forms a functional structure that can simultaneously achieve charge regulation and lunar soil action, providing a foundation for the subsequent self-burial process.

[0060] The steps involved in configuring a power supply and control system for the cable to enable it to have charge regulation and electron beam emission capabilities are as follows: Based on the aforementioned composite structure, the power management and control unit is electrically connected to the core conductive cable core, the electron beam emitting mechanism, and the surface chargeable shell. Power is obtained through the core conductive cable core or supplied through an independent power supply module. The control unit adjusts the voltage, current output, and charge polarity, enabling the surface chargeable shell to be charged with positive or negative electricity at different stages. At the same time, the electron beam emitting mechanism can emit electron beams with set intensity, direction, and duration, thereby providing controllable conditions for charge regulation and lunar soil energization in subsequent stages.

[0061] The steps involved in deploying the cable on the lunar surface and performing initial charge conditioning to clean up lunar dust are as follows: After the structure and power supply configuration are completed, the cable is laid on the lunar surface, and the control unit is activated to make the surface chargeable shell positively charged. Since lunar dust particles are usually positively charged in the lunar environment, the positive charge on the cable surface and the lunar dust will repel the lunar dust particles attached to the cable surface and form a clean area around the cable. This reduces the risk of particle adhesion and wear, and provides an unobstructed path for the electron beam to act directly on the lunar soil. This clean area serves as the basis for the subsequent electron beam energizing stage.

[0062] The steps for electron beam energizing the lunar regolith beneath the clean area to impart a negative charge to it are as follows: After the surface lunar dust is cleaned, the electron beam emitting mechanism is activated to continuously emit electron beams into the area below and to the side of the cable. The electron beams enter the interior of the lunar soil particles and are adsorbed by them, causing the lunar soil particles in this area to change from their original charged state to a negative charged state, thereby forming a negative charge distribution area below the cable. This negatively charged area serves as the object of the subsequent repulsive force between the cable and the lunar soil and constitutes the electrical basis for sedimentation drive.

[0063] The steps involved in creating a cavity are: switching the polarity of the surface charge on the cable and creating a repulsive force with the lunar soil. After the lunar soil is given a negative charge, the control unit switches the charge on the surface chargeable shell from positive to negative, causing a repulsive force between the cable and the negatively charged lunar soil below. This repulsive force acts on the lunar soil particles radially along the cable, pushing the lunar soil below the cable away and forming a low-density area or cavity structure. This cavity structure weakens the support conditions of the cable, providing a spatial basis for the cable to sink.

[0064] The steps to achieve autonomous cable settlement and continuous advancement based on a cavity structure: After the cavity is formed, the cable sinks into the cavity under the weak gravity of the moon. At the same time, the electron beam emitting mechanism continues to negatively charge the newly contacted lunar soil area and keep the surface chargeable shell in a negatively charged state, so that the repulsive effect continues to exist. This continuously forms new cavities under the cable and pushes the cable to continue to sink. This process forms a continuous sinking propulsion mechanism until the cable reaches the predetermined burial depth.

[0065] The steps to complete the burial are: stopping the process after reaching the predetermined depth and allowing the lunar soil to naturally backfill. Once the cable has sunk to the predetermined depth, the control unit stops the electron beam emission and gradually neutralizes the charge on the surface chargeable outer shell, eliminating the repulsive forces between lunar soil particles and between the lunar soil particles and the cable. Subsequently, under the influence of weak gravity and local disturbance, the surrounding lunar soil backfills around the cable and forms a covering structure, thus completing the cable's self-burial process and achieving long-term protection for the cable.

[0066] Implementation Method 3: This implementation method further describes the technical solution provided above in detail through specific embodiments, specifically: The cable body of this embodiment adopts an innovative layered composite structure. This system includes: a core conductive cable core 5, an inner insulation layer 4, a surface chargeable outer shell 2, an electron beam emitting mechanism 3, and a permeable outer sheath 1. The system also includes a power management and control module, integrated inside the cable or powered through the core conductive cable core 5, used to provide a high-voltage pulsed electric field to the electron beam emitting mechanism 3 and precisely control the charge polarity and charge quantity of the surface chargeable outer shell 2. Furthermore, the electron beam emitting mechanism 3 is arranged in a fan-shaped array at the bottom and lower sides of the cable's radial cross-section to ensure that the high-energy electron beam is directed towards the target deposition area, avoiding unnecessary electrostatic repulsion from the lunar soil above the cable.

[0067] Starting from the innermost core conductor 5, which carries electrical or communication signals and is fundamental to the cable's function, the inner insulation layer 4 provides necessary electrical insulation and physical protection. The outermost layer is the surface chargeable outer shell 2. This shell is made of specially selected conductive polymers, metallized fabrics, or carbon nanotube films and is connected to a sophisticated external control circuit, enabling it to be actively and precisely charged with positive or negative charges according to different stages of the self-burial process. Furthermore, to optimize the burial effect, a layer of permeable material with a mesh, fibrous, or porous structure can be selectively coated on the outside of the surface chargeable outer shell 2. This layer facilitates the penetration and stable adhesion of lunar dust without affecting electron beam emission and charge transfer.

[0068] The cable innovatively integrates an electron beam emitting mechanism 3, which may consist of a micro tungsten wire mesh, a nanoscale field emitter array, or a micro electron gun. These mechanisms can emit high-energy electron beams in a controlled manner, either directionally or scatterably, towards the lunar soil region below and to the sides of the cable, according to control commands. This is the core means of achieving precise charge-giving of lunar soil.

[0069] The self-burying process in this embodiment is divided into three stages.

[0070] The first stage is cable laying and initial repulsion (surface lunar dust removal). After the cable is deployed to the lunar surface, the control circuit is activated, actively imparting a positive charge to the surface chargeable outer shell 2. Considering that lunar dust particles on the lunar surface usually carry a positive charge in the natural environment, the positive charge on the cable surface will utilize a strong electrostatic repulsion force to actively push away the closely contacting lunar dust particles, thereby forming a temporary clean and dust-free zone on the cable surface and its adjacent area. This effectively prevents initial lunar dust adhesion and abrasion, and creates favorable conditions for the direct interaction between the cable and the lunar regolith below.

[0071] After the initial repulsion or synchronization is completed, the system enters the second stage: electron beam energization of the subsurface lunar regolith. At this point, the electron beam emitting mechanism 3 inside the cable is activated and continuously emits high-energy electron beams into the subsurface lunar regolith region below and to the sides of the cable. These electron beams can effectively penetrate the small amount of residual lunar dust on the surface or directly bombard the subsurface lunar regolith particles. Because electrons carry a negative charge, the bombarded lunar regolith particles are forcibly attracted to these electrons, actively changing their charge state and thus acquiring a significant negative charge.

[0072] The third stage involves surface charge conversion and secondary repulsion (creating a cavity and sinking). After the lunar regolith particles below are fully charged with negative charge by the electron beam, the cable's control circuit rapidly and precisely switches the charge state of the surface chargeable outer shell 2, making it negatively charged. At this point, the negative charge on the cable surface generates an extremely strong electrostatic repulsion force with the lunar regolith particles below, which have been charged with negative charge by the electron beam. This downward repulsion force actively applied by the cable body effectively overcomes the van der Waals forces, electrostatic forces, and the accumulation resistance under the weak gravity of the moon, thus forcibly pushing away the lunar regolith particles below the cable and actively creating a temporary lunar regolith cavity or low-density area at the bottom of the cable. After this cavity is formed, the cable, under the influence of the moon's weak gravity, will lose its support below and begin to sink autonomously into the cavity. As the cable continues to sink, the electron beam emitting mechanism 3 continuously charges the newly contacted lunar regolith with negative charge, and the cable surface also maintains a negative charge, thus forming a self-reinforcing sinking process until the predetermined depth is reached. The control circuit cuts off the power supply to the electron beam emitting mechanism 3 and neutralizes the charge on the surface shell. At this time, the electrostatic repulsion between lunar soil particles disappears, and the lunar soil cavities below and to the sides of the cable naturally collapse and backfill under the weak gravity of the moon or the disturbance caused by cable subsidence, thus achieving active coverage of the cable by the lunar soil.

[0073] The advantages of the technical solution are: 1. Extremely strong adaptability and precise control: By adjusting the intensity and charge of the electron beam, it can adapt to different lunar soil conditions and achieve precise control of the settling depth and speed. 2. Low energy consumption and lightweight design: Compared with traditional mechanical solutions, this implementation method has high integration, low energy consumption, and significantly reduces the weight of the payload, which meets the requirements of deep space exploration missions.

[0074] 3. Innovative and efficient self-burial: Abandoning traditional mechanical excavation, the cable achieves autonomous and efficient settlement and burial in the lunar environment through a mechanism of "initial repulsion - electron beam energization - charge conversion - secondary like-charge repulsion".

[0075] In practice: One specific embodiment of this method involves the following self-burial process of a lunar cable: First, a cable integrating a chargeable outer shell and an electron beam emitting mechanism 3 is deployed to the lunar surface. Upon startup, the control circuit makes the cable's outer shell positively charged, using electrostatic repulsion to remove positively charged lunar dust from the surrounding area, forming a clean area. Subsequently, the electron beam emitting mechanism 3 emits an electron beam into the lunar regolith beneath the cable, forcibly imparting a negative charge to the subsurface lunar regolith particles. Next, the control circuit quickly switches the charge of the cable's outer shell to a negative charge. At this point, a strong electrostatic repulsion force is generated between the cable and the negatively charged lunar regolith below, actively pushing the lunar regolith away and creating a cavity beneath the cable. Under the weak gravity of the moon, the cable loses support and sinks into the cavity. This process forms a self-reinforcing cycle through the continuous energization of the electron beam and the negative repulsion of the cable until the cable sinks to a predetermined depth. Finally, the surrounding lunar regolith naturally backfills, completing the self-burial of the cable, thereby achieving long-term and efficient protection for the lunar cable.
