Lunar self-cleaning cable with environmental static self-collection

Abstract

A self-cleaning cable for lunar surfaces with self-collection of environmental electrostatic charge relates to the field of cable structure technology suitable for lunar environments. Addressing the problems of existing cables easily accumulating lunar dust, experiencing decreased thermal management performance, and insulation wear in the high-static, high-dust environment of the moon, this invention proposes a self-cleaning solution based on the utilization of environmental electrostatic energy. The cable employs a coaxial multi-layer structure consisting of a conductive core, a basic insulation layer, a micro-electrostatic rectifier network, a repulsive field output electrode, and a geometric induction shell, arranged sequentially from the inside out. The geometric induction shell captures environmental charges and introduces them into the micro-electrostatic rectifier network for rectification and storage. The obtained high-voltage electrical energy is output to the repulsive field output electrode, forming a charge layer on the cable surface with the same polarity as lunar dust, thereby creating a continuous electrostatic repulsive field around the cable. This design is suitable for the long-term stable operation of cables in lunar power transmission and communication systems.

Description

Technical Field

[0001] It involves the fields of aerospace engineering and space environment protection technology, specifically the fields of cable structure and electrostatic self-cleaning protection technology under the extreme environment of the lunar surface. Background Technology

[0002] In the lunar environment, the adhesion and accumulation of lunar dust has become a key factor restricting the long-term stable operation of cables and other surface-exposed equipment. Existing research shows that lunar dust particles are generally charged under the combined effects of solar wind plasma, ultraviolet radiation, and secondary electron emission, and form a high electrostatic potential difference environment on the lunar surface, making them prone to strong adhesion to equipment surfaces. Current technologies address this problem mainly from two directions: active dust removal and passive protection.

[0003] In terms of active dust removal, existing technologies mostly employ electrodynamic dust suppression methods, such as electric field-driven electrostatic precipitators. These systems use an array of electrodes on the surface to apply an alternating or traveling wave electric field, causing lunar dust particles to migrate under the influence of the electric field force, thus achieving a removal effect. In addition, there are solutions that utilize ultrasonic vibration, mechanical shaking, or gas jetting to remove attached particles. While these technologies are effective for ground-based or short-term missions, they generally rely on external power sources or complex drive systems, resulting in high energy consumption, complex system structures, limited reliability, and difficulties in long-term stable operation. Their application is significantly constrained, especially in the energy-scarce and difficult-to-maintain lunar environment.

[0004] In terms of passive protection, existing technologies mainly focus on material surface modification, such as using low surface energy coatings, superhydrophobic or superoleophobic materials, and nanostructured coatings to reduce the adhesion of lunar dust particles. Simultaneously, there are also studies on reducing particle contact area by optimizing the surface microstructure morphology. These methods can reduce the initial adhesion probability to some extent, but due to the irregular, sharp morphology and strong electrostatic adsorption characteristics of lunar dust particles, secondary deposition or even accumulation and agglomeration can easily occur under high electrostatic potential environments. Furthermore, the coatings are prone to performance degradation under long-term irradiation and temperature cycling, making it difficult to meet long-term service requirements.

[0005] Furthermore, current research on the utilization of the electrostatic environment itself focuses on the suppression or release of static electricity accumulation, such as avoiding the discharge risk caused by charge accumulation through grounding, conductive paths, or charge dissipation materials. However, there is still a lack of systematic solutions to directly convert environmental static electricity into functional driving forces, especially in terms of achieving continuous and stable electric field regulation and particle repulsion without external power supply. Related technologies are still in the exploratory stage.

[0006] In summary, existing technologies have several drawbacks, including difficulty in achieving long-term stable active repulsion of lunar dust without external power supply, poor adaptability to high electrostatic environments, complex system structure and insufficient reliability, and difficulty in balancing cable thermal management and mechanical life protection. Summary of the Invention

[0007] To address the shortcomings of existing technologies, such as difficulty in achieving long-term stable active repulsion of lunar dust without external power supply, poor adaptability to high electrostatic environments, complex system structure and insufficient reliability, and difficulty in balancing cable thermal management and mechanical life protection, the technical solution provided by this invention is as follows: A lunar surface self-cleaning cable with environmental electrostatic self-collection capability, comprising: A coaxial multilayer structure extending along the axial direction, the coaxial multilayer structure comprising, from the inside out, a conductive cable core, a basic insulation layer covering the outside of the conductive cable core, a miniature electrostatic rectifier network disposed on the outside of the basic insulation layer, a repulsive field output electrode disposed on the outside of the miniature electrostatic rectifier network, and a geometric induction shell covering the outside of the repulsive field output electrode. The geometric sensing shell is a ring-shaped shell structure made of a high dielectric constant composite material, and its outer surface is provided with a micron-sized cone-shaped or spike-shaped geometric array uniformly distributed along the circumference. This array is used to generate a local electric field enhancement and capture environmental charges in the lunar electrostatic environment. The geometric sensing shell is connected to the micro electrostatic rectifier network through a conductive path to introduce the captured charges into the micro electrostatic rectifier network. The micro electrostatic rectifier network includes a high-voltage Schottky diode array and a high-voltage capacitor disposed on a flexible substrate. The high-voltage Schottky diode array forms a unidirectional rectification structure to convert input charges of different polarities into currents in the same direction and store them in the high-voltage capacitor. The high-voltage capacitor is used to accumulate the rectified charges to form high-voltage electrical energy. The repulsive field output electrode is a conductive thin film structure continuously covering the circumference of the cable and electrically connected to the high-voltage capacitor. This electrode is used to carry and output the high-voltage electrical energy to form a charge layer with the same polarity as lunar dust on the outer surface of the cable, thereby forming an electrostatic repulsive field around the cable to prevent lunar dust from adhering.

[0008] Furthermore, in a preferred embodiment, the conductor core is a multi-strand stranded conductor structure or a single-strand conductor structure, and the material is copper or a copper alloy.

[0009] Furthermore, in a preferred embodiment, the basic insulation layer is a continuous cylindrical shell structure covering the outside of the conductive cable core, and is made of a high-molecular insulating material that is resistant to radiation and high and low temperature cycling.

[0010] Furthermore, in a preferred embodiment, the micro electrostatic rectifier network is configured as a ring-shaped flexible circuit structure, the flexible substrate of which is a polyimide film, and the high-voltage Schottky diode array is connected in a full-bridge rectification manner.

[0011] Furthermore, in a preferred embodiment, the high-voltage capacitor is an ultra-thin high-voltage ceramic capacitor, which is electrically connected to the high-voltage Schottky diode array.

[0012] Furthermore, in a preferred embodiment, the repulsive field output electrode is a transparent conductive thin film structure, made of indium tin oxide or carbon nanotube material, and continuously covers the cable circumferentially.

[0013] Based on the same inventive concept, this invention also provides an electrical control method for a lunar surface self-cleaning cable with environmental electrostatic self-collection, implemented based on the aforementioned cable, comprising: The step of introducing the ambient charge captured by the geometric induction shell into a micro electrostatic rectifier network to form a charge input; The step of rectifying the charge input through a high-voltage Schottky diode array to form a unidirectional current; The step of accumulating the unidirectional current through a high-voltage capacitor to form stable high-voltage electrical energy; The step of outputting the high-voltage electrical energy to the repulsive field output electrode to form a charge layer of the same polarity on the cable surface; The step of forming an electrostatic repulsion field around the cable based on the same polarity charge layer to achieve the repulsion of lunar dust.

[0014] 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.

[0015] 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.

[0016] Based on the same inventive concept, the present invention also provides a computer program product, which, when executed, implements the method described.

[0017] Compared with the prior art, the advantages of the technical solution provided by the present invention are as follows: The geometric sensing shell, through its micron-scale conical geometric array structure, utilizes the concentrated electric field effect at the tip to efficiently capture scattered charges in the lunar environment. Compared to existing charge sensing methods that rely on planar conductive layers or simple conductive coatings, this structure significantly improves the efficiency of collecting environmental static electricity, enabling a stable charge source without external power supply. This provides a continuous energy foundation for the subsequent establishment of a repulsive field, solving the problem of strong dependence on external energy in existing active dust removal technologies.

[0018] The application of high dielectric constant polyimide-ceramic nanocomposite material in geometric sensing shell enables the shell to not only have excellent charge accumulation ability, but also good radiation resistance and thermal stability. Compared with traditional single polymer material coatings, this composite material has less performance degradation under strong lunar radiation and extreme temperature difference environment, thus ensuring the long-term stable operation of the charge collection structure and solving the problem of easy aging and failure of existing passive coatings.

[0019] The repulsion field output electrode uses a transparent conductive indium tin oxide or carbon nanotube thin film. In the implementation, it is used to carry and uniformly distribute the rectified high-voltage charge, so that a stable and uniform electric field repulsion layer is formed on the outer surface of the cable. Compared with traditional local electrodes or discontinuous conductive layers, this structure can avoid the risk of discharge caused by local electric field distortion and charge concentration, thereby improving the stability and coverage of the repulsion field and ensuring that dust cannot adhere to the entire cable surface.

[0020] In this implementation, the miniature electrostatic rectifier network integrates a high-voltage Schottky diode array to achieve unidirectional conduction and rectification of environmental induced charges of varying directions and intensities. This transforms disordered alternating current or pulsed charges into stable unipolar currents. Compared to existing schemes that rely solely on conductive paths to conduct charges, this structure effectively avoids charge backflow and energy loss, improves energy utilization efficiency, and thus ensures the stability of subsequent energy storage and output processes.

[0021] The full-bridge rectification and filtering circuit in the micro electrostatic rectifier network further smooths the collected charge in the embodiment, significantly reducing the output current fluctuation. Compared with the unfiltered pulsed charge output, this structure can form a more stable DC power, providing conditions for establishing a continuous and stable repulsive electric field and avoiding the problem of short-term adhesion of lunar dust caused by intermittent failure of the electric field.

[0022] In this implementation, the ultrathin high-voltage ceramic capacitor performs the functions of charge storage and voltage accumulation. By continuously accumulating weak environmental charges, it gradually increases the voltage to a usable level of 200V to 500V. Compared with existing passive conductive structures that cannot store energy or have limited energy storage capacity, this feature can achieve the effect of "long-term accumulation of micro-energy", enabling the system to maintain effective repulsion capability in low charge density environments, thereby improving the system's adaptability to different lunar environments.

[0023] Through the boost regulation mechanism formed by the rectifier network and capacitor, the energy conversion process from low-intensity random electrostatics to a stable high-voltage electric field is realized in the implementation. Compared with the traditional electric field driven dust removal technology that requires an external boost power supply, this structure can build a high-intensity repulsion field without external power supply, which significantly reduces system complexity and energy consumption, while improving system reliability.

[0024] In this embodiment, the repulsive field output electrode releases the stored high-voltage electrical energy to the surface of the cable, causing it to become charged with the same polarity as the lunar dust, thereby forming a continuous electrostatic repulsive field of the same polarity around the cable. Compared with existing technologies that remove particles by vibration or pneumatic means, this feature can generate a repulsive effect before the lunar dust approaches, achieving "preventive protection" and avoiding the adhesion of lunar dust to the subsequent cleaning process.

[0025] The synergistic integration of the geometric sensing shell, rectifier network, capacitor and output electrode in the multi-layer structure forms a complete closed-loop system from charge acquisition to electric field output in the implementation. Compared with existing discrete dustproof devices or external modules, this integrated structure significantly reduces system complexity and connection failure risk, while improving the overall structure's flexibility and layability, making it suitable for large-scale cable deployment scenarios.

[0026] In this implementation, the core conductor and the basic insulation layer serve as the functional body and electrical isolation basis of the cable. Under the protection of the outer self-cleaning structure, they can avoid the problems of decreased thermal radiation performance and mechanical wear caused by the adhesion of moon dust. Compared with traditional cables without protective structures, this combination can significantly extend the service life of the cable and maintain its electrical performance stability, thereby achieving a simultaneous improvement in thermal management performance and mechanical reliability.

[0027] In this implementation, the overall structure utilizes the high electrostatic environment of the lunar surface as the sole energy source, enabling continuous operation without external power supply. Compared to active dust removal systems that rely on solar energy or external power, this feature allows the system to remain operational in extreme shadowed areas or energy-constrained scenarios, thereby significantly improving the system's applicability and mission continuity in complex lunar environments.

[0028] Suitable for use in long-term operation of cables and similar exposed infrastructure in lunar environments to achieve self-cleaning and dust and abrasion protection. Attached Figure Description

[0040] A computer program product is also provided, which, when executed, implements the method described.

[0041] Implementation Method Two: This implementation method is a further detailed description of the technical solution provided in Implementation Method One, specifically: This embodiment provides a lunar self-cleaning cable structure with environmental electrostatic self-collection function. The whole structure is a coaxial multi-layer composite structure that extends continuously along the axis. From the inside to the outside, it includes a conductive cable core 1, a basic insulation layer 2, a micro electrostatic rectifier network 3, a repulsive field output electrode 4, and a geometric induction shell 5. The layers are tightly attached to each other in the radial direction to form an integrated sheath structure.

[0042] The conductor core 1 is located in the innermost layer of the structure and is used to transmit electrical energy or signals. It can be in the form of multi-strand stranded conductor or single-strand conductor. The material is preferably copper or copper alloy to ensure good conductivity and flexibility, and to maintain stable electrical connection performance during long-distance laying.

[0043] The basic insulation layer 2 covers the outside of the conductor core 1 to achieve electrical isolation and mechanical protection. It can be made of radiation-resistant and high and low temperature cycle-resistant polymer insulation material, such as fluoropolymer or modified polyethylene. It is formed into a uniform and continuous cylindrical shell structure by extrusion molding, so that the conductor core is completely isolated from the external functional layer, preventing electrical leakage and providing basic mechanical strength.

[0044] The miniature electrostatic rectifier network 3 is disposed on the outside of the basic insulation layer 2 and is uniformly distributed along the circumference of the cable in the form of a ring-shaped thin layer. It consists of a flexible substrate and circuit units integrated on it. The flexible substrate can be made of polyimide film. The circuit units include multiple high-voltage Schottky diodes and high-voltage ceramic capacitors. A full-bridge rectification and energy storage structure is formed by printing circuits. Each diode is connected in a unidirectional topology so that the charge induced from the outer layer is converted into a current in a single direction under any polarity input condition. At the same time, the current is continuously accumulated by the capacitor, thereby gradually converting the discrete and unstable environmental static electricity into stable DC high-voltage electrical energy.

[0045] The repulsive field output electrode 4 is disposed on the outside of the micro electrostatic rectifier network 3. It is a continuous conductive thin film structure and is electrically connected to the output end of the rectifier network 3. It is used to carry and release the DC high voltage charge. The electrode is preferably formed of a transparent conductive material, such as an indium tin oxide thin film or a carbon nanotube network structure. A uniform and continuous conductive layer is formed by coating or deposition process, so that the charge can be evenly distributed on the entire cable surface, thereby forming a stable electric field distribution in space and avoiding local electric field concentration that leads to discharge or shielding effect.

[0046] The geometric sensing shell 5 is located on the outermost layer. It is a dielectric material shell with a specific microstructure and completely covers the repulsive field output electrode 4. The geometric sensing shell 5 is made of a high dielectric constant composite material, such as a composite system of polyimide and ceramic nanoparticles. A uniformly distributed array of micron-sized cone-shaped or spike-shaped structures is constructed on its outer surface. This structure forms a large number of local electric field enhancement points in space. When the cable is in the high electrostatic environment of the lunar surface, it can significantly enhance the attraction and capture of surrounding charges, so that positive and negative charges in the environment are preferentially collected to the surface of the shell and introduced into the micro electrostatic rectifier network 3 through the inner conductive path.

[0047] In the specific operation, when the cable is exposed to the lunar environment or buried in the lunar soil, the geometric induction shell 5 first generates an electric field distortion effect through the pointed structure on its surface, inducing free charges or charged dust in the surrounding space to its surface and forming a charge-rich area. Then, these charges enter the micro electrostatic rectifier network 3 through the conductive connection path between the shell and the interior. In this network, each diode performs unidirectional screening of the input charge, so that the charge flows in a uniform direction and enters the capacitor for storage. During the continuous charge input process, the voltage in the capacitor gradually increases. When the voltage reaches the set range, the high-voltage electrical energy is output to the repulsive field output electrode 4 through the circuit connection, so that the electrode as a whole carries a charge with the same polarity as the lunar dust.

[0048] As the surface charge of the repulsive field output electrode 4 continues to accumulate, a stable electrostatic repulsive field is formed around the cable. This repulsive field generates an electric field force with the same polarity on the charged dust particles that approach the cable, so that the dust particles are repelled outward before they even come into contact with the cable surface. As a result, they cannot adhere to the surface of the geometric induction shell 5, or are quickly pushed away after initial contact, thus achieving a continuous self-cleaning effect.

[0049] During long-term operation, the energy storage unit composed of the micro electrostatic rectifier network 3 and the capacitor can continuously accumulate weak and intermittent charges in the environment. Even under conditions of electrostatic fluctuations or short-term insufficient charge supply, it can still maintain the potential stability of the repulsive field output electrode 4, thereby ensuring the continuity of the self-cleaning function. At the same time, each layer of the structure is made of flexible materials, which gives the overall cable good bending performance and laying adaptability, enabling long-distance deployment in complex lunar terrain.

[0050] Through the synergistic effect of the above structure and construction, the cable achieves a complete closed-loop process from environmental charge acquisition, rectification and energy storage to electric field output without the need for external power supply, forming a continuous and stable electrostatic repulsion field. This effectively prevents lunar dust from adhering to and accumulating on the cable surface, ensuring the cable's thermal radiation performance, electrical performance and mechanical integrity, and meeting the requirements for long-term reliable operation in the extreme environment of the lunar surface.

[0051] In terms of electronic control: A method for realizing a lunar surface self-cleaning cable with environmental electrostatic self-collection function is proposed. The overall idea is based on the multi-layer composite structure of the cable to sequentially complete environmental charge capture, charge rectification and storage, and repulsion field construction, thereby achieving continuous repulsion and self-cleaning of lunar dust.

[0052] First, the cable structure is constructed, forming a multi-layered coaxial structure from the inside out, consisting of a conductive cable core, a basic insulation layer, a micro electrostatic rectifier network, a repulsive field output electrode, and a geometric induction shell. The conductive cable core is used to transmit electrical energy or signals, the basic insulation layer is used for electrical isolation, the micro electrostatic rectifier network is used for charge processing and energy storage, the repulsive field output electrode is used to output charges to form an electric field, and the geometric induction shell is used to capture environmental charges. This structure serves as the basic carrier for subsequent charge acquisition and conversion.

[0053] Based on the completion of the cable structure construction, the outermost geometric induction shell is designed and fabricated with microstructure. A uniformly distributed micron-scale cone or spike array structure is formed on its outer surface, and a high dielectric constant composite material is selected for molding. This shell can generate a local electric field enhancement effect in the lunar environment, thereby forming multiple charge attraction points around the cable. These charge attraction points serve as input terminals for environmental charge capture, providing a source for subsequent charge transfer.

[0054] Based on the environmental charge captured by the geometric induction shell, the captured positive and negative charges are introduced into a micro electrostatic rectifier network through a conductive path set on its inner side, so that the disordered charges in the environment enter the circuit system, and the charges serve as input signals for the rectification and energy storage process.

[0055] After the charge enters the micro electrostatic rectifier network, a unidirectional conduction structure is formed by multiple high-voltage Schottky diodes deployed on a flexible substrate, so that the input charge is guided to flow in the same direction under any polarity condition. The charge direction is unified through a full-bridge rectification connection, thereby converting the originally unstable environmental charge into a unipolar current, which serves as the input current for the subsequent energy storage process.

[0056] Based on the unipolar current, the charge is continuously accumulated through a high-voltage ceramic capacitor electrically connected to the diode array, so that the weak input charge gradually accumulates in the capacitor and raises the potential. Over time, a stable high-voltage electrical energy is formed in the capacitor, which serves as the energy source for the repulsive field output.

[0057] After the capacitor has completed charge accumulation and formed a stable potential, the high-voltage electrical energy is transferred to the repulsive field output electrode through the electrical connection path, so that the repulsive field output electrode as a whole is charged with a uniform polarity and a uniformly distributed charge layer is formed on the outer surface of the cable. This charge layer serves as the basis for the formation of the repulsive field.

[0058] Based on the charge on the output electrode of the repulsive field, a stable electrostatic field is formed in the space around the cable. The polarity of this electrostatic field is consistent with the polarity of the charge carried by the lunar dust particles, thereby forming a continuous repulsive force field of the same polarity on the outer side of the cable surface. This causes the lunar dust particles approaching the cable to be subjected to an outward electric field force and pushed away before they even come into contact with the surface. This repulsive force field is the core mechanism for realizing the self-cleaning function.

[0059] Based on the formation of a stable repulsive field, the repulsive field maintains a stable output during long-term operation through continuous environmental charge collection and capacitor energy storage. Even in the event of environmental charge fluctuations or short-term supply shortages, the electric field strength can still be maintained through the stored electrical energy, thereby achieving continuous self-cleaning and protection functions of the cable under different lunar surface conditions.

[0060] Based on the above process, through the tight integration and flexible construction of each layer of structure, the cable can have good mechanical flexibility and environmental adaptability while ensuring electrical performance. This enables it to be laid and operated for a long time under the complex terrain conditions of the lunar surface, and ultimately achieves anti-dust adhesion, self-cleaning and comprehensive protection of the cable's thermal and mechanical properties without the need for external power supply.

[0061] Implementation Method 3, in conjunction with Appendix Figure 1 This embodiment describes the technical solution provided above in further detail through specific examples. Specifically: This embodiment proposes a functional composite capacitor-type cable sheath, characterized in that it uses the environmental electrostatic potential difference as an energy source, and captures, rectifies and outputs the same electrostatic charge through geometric field control to drive the continuous repulsion of lunar dust.

[0062] The cable structure in this embodiment consists of, from the outside in, a geometric induction shell 5, a repulsive field output electrode 4, a micro-electrostatic rectifier network 3, and a core conductive cable core 1. The outermost layer is a multi-layered geometric induction shell 5, made of a high-dielectric-constant polyimide-ceramic nanocomposite material, with a micron-scale conical geometric array on its surface. Closely attached to the inner side of the induction shell is the repulsive field output electrode 4, composed of a transparent and highly conductive indium tin oxide (ITO) or carbon nanotube film. Below the electrode layer is the micro-electrostatic rectifier network 3, which includes a high-voltage Schottky diode array and an ultra-thin high-voltage ceramic capacitor printed on a flexible film. The innermost layer is the core conductive cable core 1, wrapped by a basic insulating layer 2.

[0063] Regarding the function of each layer, the outermost geometric induction shell 5 utilizes the electrostatic concentration effect generated by its sharp geometric features to efficiently capture and accumulate high electrostatic potential charges in the lunar environment, much like a "lightning rod." These captured intermittent charges enter the micro electrostatic rectifier network 3 for conversion. As the core of energy conversion, the micro electrostatic rectifier network 3 includes a passive acquisition circuit, specifically employing a full-bridge rectifier and filter circuit to achieve rectification and voltage boosting, continuously storing electrical energy in a high-voltage capacitor. The stored DC high voltage (200V-500V) is then delivered to the repulsive field output electrode 4, causing the cable surface to acquire a high charge with the same polarity as lunar dust (usually positive). This strong electrostatic repulsion generated by the like charge continuously pushes away lunar dust particles approaching the cable, achieving passive self-cleaning.

[0064] This implementation method has significant advantages in practical applications. First, the structure effectively utilizes the "adverse factor" (high electrostatic potential) of the lunar environment, transforming it into a "favorable force" for maintaining cable cleanliness, achieving continuous protection with zero external power consumption. Second, when the cable is buried or in a lunar dust environment, the repulsive force generated by the self-cleaning function effectively overcomes the van der Waals forces and electrostatic attraction of lunar dust, preventing lunar dust from adhering and agglomerating on the cable surface. This not only ensures the thermal management efficiency of the cable and avoids thermal failure caused by dust accumulation, but also eliminates the risk of insulation damage caused by mechanical wear by blocking contact between hard lunar dust particles and the sheath, greatly improving the reliability and sustainability of lunar infrastructure. This system mainly utilizes the electrostatic repulsive field maintained by the high-voltage environment of the lunar surface. In extremely shadowed areas where energy is extremely scarce, the system can enter an intermittent pulse operation mode.

[0065] When the cable is exposed to the high-voltage electrostatic environment of the moon or buried in lunar soil, the outermost geometric induction shell 5 begins to function. Utilizing the micron-sized "spiky" structure on its surface, it generates a sharp electric field distortion, acting like countless miniature lightning rods to forcibly attract and capture scattered positive and negative charges in the lunar surface or surrounding soil. The captured random charges enter the miniature electrostatic rectifier network 3 through conductive paths. At this point, diodes in the circuit act as "one-way valves," straightening the induced charges of varying directions and intensities into a single-direction current, ensuring that electrical energy can only be stored internally and not lost externally. The straightened charges are then fed into a high-voltage miniature capacitor for "accumulation." As the induction process continues, the voltage within the capacitor continuously increases. Through voltage boosting regulation in the circuit, the weak environmental electrostatic energy is converted into a stable DC high voltage sufficient to generate repulsive force (typically accumulating to 200V-500V). The accumulated high-voltage electrical energy is released onto the repulsive field output electrode 4, causing the outermost surface of the cable to acquire a charge of the same polarity as the lunar dust. At this point, a strong electrostatic protective field is generated around the cable. According to the principle of "like charges repel," both incoming lunar dust and surrounding lunar soil particles will be subjected to a strong outward thrust. Under this continuous thrust, lunar dust cannot land or adhere to the cable surface, thus achieving all-weather self-cleaning and abrasion protection for the cable without the need for an external power source.

However, the above-described specific embodiments are not intended to limit the present invention.
