Description

Technical Field

[0001] The present invention relates to the field of lunar dust transport, and specifically to the lunar dust transport by traveling wave electric curtain based on three-dimensional electrodes. Background Art

[0002] Human exploration and utilization of the Moon have become an integral part of space exploration. Driven particularly by the demands of deep space exploration and the construction of lunar bases, the in-situ utilization of lunar resources has become a research hotspot. Currently, the primary resources on the lunar surface include oxygen, water, and other useful elements in the lunar soil. Effectively acquiring and utilizing these resources is key to achieving long-term lunar existence and sustainable development.

[0003] With existing technologies, lunar rovers and other robotic equipment have already been used in several lunar surface exploration missions. For example, the US Apollo program and China's Chang'e series of probes, particularly the successful landing and sample return of Chang'e-5, have provided a wealth of fundamental data on the composition of the lunar surface, lunar dust properties, and environmental conditions. This information lays a crucial foundation for the subsequent transportation and utilization of lunar dust resources.

[0004] However, due to the peculiarities of the lunar environment, including microgravity, high radiation, extreme temperature differences, and the highly abrasive nature of lunar dust, efficient and stable material transportation on the lunar surface remains a huge challenge. Existing equipment such as lunar rovers are mainly transported mechanically, which has many limitations. For example, the high adhesion of lunar dust can cause equipment wear, low transportation efficiency, and even affect the normal operation of equipment. In addition, lunar dust easily floats in the air (which is a vacuum on the moon), making it easy for it to cause blockage or damage when it contacts the surface, posing a problem for the long-term stability of the transportation system.

[0005] In recent years, the application of electrokinetic transport technologies in the lunar environment has gradually attracted the interest of researchers. For example, transporting charged particles through electric fields is an effective method, and some studies have explored the directional transport of lunar dust using electrostatic fields generated by electrodes. However, these methods generally rely on relatively simple planar electrode structures, which pose problems such as uneven electric field distribution, high energy consumption, and easy electrode wear. In particular, the effective utilization of electric fields is limited, making it ineffective in addressing the demand for lunar dust transport due to the complex lunar terrain.

[0006] Therefore, the existing technology has the following major technical problems in terms of efficiency and stability of lunar dust transportation:

[0007] Uneven electric field distribution: The traditional planar electrode design causes the electric field to decay rapidly in the vertical direction, making it difficult to effectively utilize the entire electric field space for particle transport.

[0008] Poor equipment durability: The high abrasiveness of lunar dust makes traditional electrodes prone to wear, reducing the service life and reliability of the system.

[0009] High energy consumption: Due to the limitations of electric field distribution, traditional transport devices consume a lot of energy and cannot meet the needs of long-term and efficient transport. Summary of the Invention

[0010] In order to solve the problems existing in the prior art of low electric field utilization, easy wear of equipment and high energy consumption in the existing lunar dust transportation work, the technical solution provided by the present invention is as follows:

[0011] A traveling wave electric curtain lunar dust transport device based on three-dimensional electrodes, the device comprising:

[0012] substrate;

[0013] A wedge-shaped microstructure is provided on the upper surface of the substrate, wherein the wedge-shaped microstructure is in the shape of a triangular prism;

[0014] The electrodes are arranged on the side walls of the wedge-shaped microstructure and are used to generate electrodes and transport lunar dust particles.

[0015] Furthermore, a preferred embodiment is provided, wherein the right triangular prism contacts the upper surface of the substrate through one of its faces.

[0016] Furthermore, a preferred embodiment is provided, wherein the electrode is a comb-shaped electrode.

[0017] Furthermore, a preferred embodiment is provided, wherein the comb-shaped electrodes are three-dimensional comb-shaped electrodes.

[0018] Furthermore, a preferred embodiment is provided, wherein there are at least two wedge-shaped microstructures, which are oriented in the same direction and are uniformly arranged in sequence on the substrate.

[0019] Furthermore, a preferred embodiment is provided, which further includes a protective coating covering the surface of the electrode.

[0020] Based on the same inventive concept, the present invention also provides a method for transporting lunar dust using a traveling wave electric curtain based on three-dimensional electrodes. The method is implemented based on the above-mentioned device and includes:

[0021] Steps for collecting the motion state of lunar dust particles;

[0022] The step of adjusting the driving voltage according to the motion state;

[0023] The step of driving the electrodes according to the adjusted driving voltage.

[0024] Based on the same inventive concept, the present invention also provides a computer storage medium for storing a computer program. When the computer reads the computer program, the computer executes the method described.

[0025] Based on the same inventive concept, the present invention also provides a computer, comprising a processor and a storage medium. When the processor reads the computer program stored in the storage medium, the computer executes the method described above.

[0026] Based on the same inventive concept, the present invention also provides a computer program product, which is a computer program. When the computer program is executed, the method described above is implemented.

[0027] Compared with the prior art, the technical solution provided by the present invention is beneficial in that:

[0028] By combining three-dimensional comb electrodes with wedge-shaped microsurface structures, the technical solution provided by this invention effectively improves the uniformity of electric field distribution. Compared with traditional planar electrodes, the three-dimensional comb electrode design significantly reduces the vertical decay rate of the electric field, thereby improving the effective utilization of the electric field. This optimization achieves more stable particle movement during lunar dust transport, reduces transport interruptions caused by uneven electric fields, and enhances the controllability of lunar dust particle movement, thereby improving the accuracy and efficiency of the transport process.

[0029] The addition of a protective coating significantly improves the electrodes' wear resistance and radiation resistance, enabling the device to operate stably and long-term in the extreme lunar environment. Compared to traditional electrode structures, the comb-shaped electrode design combined with the protective coating significantly reduces physical damage to the electrodes caused by the highly abrasive nature of lunar dust. This improvement significantly extends the device's service life, reduces the need for frequent repairs and replacements, and improves system reliability.

[0030] By optimizing the spatial arrangement of the electrodes and the shape of the wedge-shaped microsurface structures, the technical solution provided by this invention significantly improves the effective utilization of the electric field and reduces ineffective diffusion and energy loss. Compared to traditional planar electrode designs, the three-dimensional comb-shaped electrode arrangement reduces the generation of ineffective areas of the electric field, allowing the system to more efficiently convert electrical energy into a driving force on lunar dust particles, reducing overall energy consumption. This optimization enables the device to transport lunar dust more efficiently during continuous operation, extending the operating cycle and eliminating the need for frequent energy replenishment.

[0031] The combination of three-dimensional electrodes and a wedge-shaped microsurface structure significantly enhances the system's heat dissipation performance. The specialized electrode arrangement effectively dissipates heat into the surrounding environment during operation, preventing performance degradation or failure due to electrode overheating. This improvement is particularly suitable for long-term, continuous lunar dust transport missions, ensuring system stability and reliability. Compared to the heat dissipation performance of traditional planar electrodes, the three-dimensional comb-shaped electrode design allows for more controllable system temperature, avoiding system downtime or failure caused by localized overheating.

[0032] The wedge-shaped microsurface structure, through a combination of varying slope angles, enables unidirectional flow of lunar dust particles from a low to a high angle. This structural design allows the electric field to overcome gravity and adhesion forces, ultimately achieving stable unidirectional transport. Compared to traditional mechanical reciprocating transport, this electric transport method not only reduces mechanical friction losses but also significantly improves transport efficiency and controllability of particle flow. This unidirectional flow makes the system particularly effective in long-distance transport missions, effectively avoiding the problem of reverse movement or stagnation of particles.

[0033] Compared to other existing research, the technical solution provided by this invention, through the design of three-dimensional electrodes and the optimization of wedge-shaped micro-surface structures, not only effectively solves the problems of uneven electric field, severe wear, and high energy consumption that exist in traditional electrode structures, but also offers significant advantages in heat dissipation and device stability. Compared to traditional planar electrodes, this innovative design makes electric field utilization more efficient, significantly extends the service life of the equipment, and significantly improves the efficiency of lunar dust transportation, providing more reliable technical support for the development and utilization of lunar resources.

[0034] It is suitable for use in lunar dust transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Substrate 3: As the supporting structure of the entire device, substrate 3 provides physical support for the electrodes and microstructures, ensures their stability, and combines with other components to form a complete transport surface.

[0048] 3D comb electrodes 1: Distributed on a wedge-shaped surface, these electrodes are used to generate an alternating electric field. Their design optimizes the electric field distribution, improving both its uniformity and the overall system's sensitivity.

[0078] Implementation Method 11: Combination Figure 1-4This embodiment further describes the above technical solution in detail through specific examples, specifically:

[0079] The lunar dust transport mechanism is responsible for transporting the small-sized lunar dust obtained after processing by the screening machine to the test section of the lander for relevant experiments. A simple transport surface is achieved by adding a wedge-shaped micro-surface structure to the array electrode plate. By applying an alternating voltage to the embedded electrodes, the particles are driven, and with the assistance of the wedge-shaped micro-surface structure, the transport surface can transport lunar dust upward along an inclined surface. However, the effective utilization rate of the electric field on this surface is too low. The electric field generated by the array electrodes decays rapidly in the vertical direction, and most of the electric field is not within the effective transport space, resulting in high energy consumption and poor transport efficiency of the overall structure.

[0080] Therefore, structural improvements are made on this simple transport surface to obtain a traveling wave electric curtain lunar dust transport surface based on a three-dimensional comb electrode 1. The original embedded array electrode is changed into a patch of three-dimensional comb electrodes 1 arranged along the wedge-shaped microstructure 2. The improved three-dimensional comb electrode 1 is obviously more uniform and regular above the electrode. By optimizing the shape and spacing of the wedge-shaped microstructure 2, the electric field distribution can be better guided, thereby achieving the purpose of enhancing the overall performance. The improved electrode adopts a three-dimensional comb electrode 1 and is combined with the substrate 3 in the form of a patch. The required wedge-shaped microstructure 2 is specially processed, and the substrate 3 is matched. A layer of three-dimensional comb electrode 1 is processed by micro-nano technology, and finally a layer of protective coating 4 is covered on the surface. This design can improve the durability and stability of the electrode, and the service life of the surface can be extended after improvement.

[0081] The three-dimensional comb electrode 1 distribution method has the following advantages compared to a simple splicing surface:

[0082] Efficient electric field distribution: The three-dimensional comb-shaped electrodes 1 inherently possess excellent electric field distribution characteristics, which can reduce localized excessive electric field strength and prevent electrode breakdown or energy loss. This three-dimensional distribution further optimizes the electric field distribution, ensuring overall uniformity while achieving local enhancement when needed.

[0083] Better heat dissipation performance: The structural design of the three-dimensional comb-shaped electrode 1 is distributed on the surface of the wedge-shaped microstructure 2 to enhance the heat dissipation effect and prevent the electrode from overheating, which can improve work efficiency and prevent performance degradation or failure caused by overheating.

[0084] Reduced leakage and loss: The three-dimensional comb-shaped electrode design effectively reduces electric field non-uniformity and lowers the probability of leakage current. Combined with the wedge-shaped microstructure, it also optimizes surface effects, reducing energy loss and making the device more energy efficient.

[0085] The improved design of the three-dimensional comb electrode 1 combined with the wedge-shaped microstructure 2 significantly improves the uniformity of the electric field distribution and the device's response sensitivity, while also providing better heat dissipation and mechanical stability. Its ease of manufacture and superior performance make this structure promising for a wide range of future applications.

[0086] The above further describes the technical solution provided by the present invention in detail through several specific embodiments in order to highlight the advantages and benefits of the technical solution provided by the present invention. However, the several specific embodiments described above are not intended to limit the present invention. Any reasonable modification and improvement of the present invention, combination of embodiments and equivalent replacement based on the spirit and principles of the present invention should be included in the scope of protection of the present invention.
