Description

Technical Field

[0001] The 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] The exploration and utilization of the moon by humans has become an important part of space exploration. Especially driven by the needs of deep space exploration and the construction of lunar bases, the in-situ utilization of lunar resources has become one of the research hotspots. At present, the main resources on the lunar surface include oxygen, water and other useful elements in the lunar soil. How to effectively obtain and utilize these resources is the key to achieving long-term existence and sustainable development on the moon.

[0003] In the existing technology, lunar rovers and other mechanical equipment have been used for some exploration missions on the lunar surface. For example, the Apollo program of the United States and the Chang'e series of probes of China, especially the successful landing and sample return of Chang'e 5, have provided a large amount of basic data on the composition of the lunar surface, the characteristics of lunar dust and environmental conditions. This information has laid an important foundation for the subsequent transportation and resource utilization of lunar dust.

[0004] However, due to the particularity of the lunar environment, including microgravity, high radiation, extreme temperature differences, and the high abrasiveness of lunar dust, efficient and stable material transportation on the lunar surface still faces huge challenges. 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 is easily suspended in the air (vacuum on the moon), making it easy to cause blockage or damage when it contacts the surface, which poses a problem for the long-term stability of the transportation system.

[0005] In recent years, the application of electric transport technology in the lunar environment has gradually attracted the interest of researchers. For example, transporting charged particles through the action of electric fields is an effective method, and some studies have explored the directional transport of lunar dust through the electrostatic field generated by electrodes. However, these methods usually rely on relatively simple planar electrode structures, and there are problems such as uneven electric field distribution, high energy consumption, and easy wear of electrodes. In particular, the effective utilization space of the electric field is limited, and it cannot effectively cope with the demand for lunar dust transport caused by the complex terrain of the moon.

[0006] Therefore, the existing technology has the following main 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, such as 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 disposed on the upper surface of the substrate, wherein the wedge-shaped microstructure is in the shape of a triangular prism;

[0014] The electrode is arranged on the side wall of the wedge-shaped microstructure and is used to generate an electrode and transport lunar dust particles.

[0015] Furthermore, a preferred embodiment is provided, wherein the right-angled 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 also includes a protective coating covering the surface of the electrode.

[0020] Based on the same inventive concept, the present invention also provides a traveling wave electric curtain lunar dust transport method based on a three-dimensional electrode, the method is implemented based on the device, and includes:

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

[0022] According to the motion state, adjusting the driving voltage step;

[0023] The step of driving the electrode 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, and when the computer reads the computer program, the computer executes the described method.

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

[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 the three-dimensional comb electrode with the wedge-shaped micro-surface structure, the technical solution provided by the present invention effectively improves the uniformity of the electric field distribution. Compared with the traditional planar electrode, the three-dimensional comb electrode design significantly reduces the attenuation rate of the electric field in the vertical direction, thereby improving the effective utilization rate of the electric field. This optimization achieves more stable particle movement during the transportation of lunar dust, reduces the problem of transportation interruption caused by uneven electric field, and also enhances the controllability of the movement of lunar dust particles, thereby improving the accuracy and efficiency of the transportation process.

[0029] By adding a protective coating, the wear resistance and radiation resistance of the electrode are significantly improved, allowing the device to work stably and for a long time in the extreme environment of the moon. Compared with the traditional electrode structure, the comb electrode design combined with the protective coating greatly reduces the physical damage to the electrode caused by the high abrasiveness of the moon dust. This improvement greatly extends the service life of the device, reduces the need for frequent maintenance and replacement, and improves the reliability of the system.

[0030] By optimizing the spatial arrangement of the electrodes and the shape of the wedge-shaped micro-surface structure, the technical solution provided by the present invention significantly improves the effective utilization rate of the electric field and reduces the ineffective diffusion of the electric field and energy loss. Compared with the traditional planar electrode design, the arrangement of the three-dimensional comb-shaped electrodes reduces the generation of ineffective areas of the electric field, so that the system can more efficiently convert electrical energy into a driving force for the lunar dust particles, reducing overall energy consumption. This optimization enables the device to transport lunar dust more efficiently during continuous operation, extending the working cycle without the need for frequent energy replenishment.

[0031] The combination of three-dimensional electrodes and wedge-shaped micro-surface structures significantly enhances the heat dissipation performance of the system. The special arrangement of the electrodes allows the heat to be effectively dispersed into the surrounding environment during operation, preventing performance degradation or failure due to overheating of the electrodes. This improvement is particularly suitable for long-term continuous lunar dust transport missions, ensuring the stability and reliability of the system. Compared with the heat dissipation performance of traditional planar electrodes, the three-dimensional comb electrode design makes the system temperature more controllable, avoiding system shutdown or failure caused by local excessive temperature.

[0032] The wedge-shaped micro-surface structure realizes the unidirectional flow of lunar dust particles from small inclination angle to large inclination angle through the combination of different slope angles. This structural design enables lunar dust particles to smoothly overcome gravity and adhesion under the action of electric field force, and finally achieve stable unidirectional transport. Compared with the traditional mechanical reciprocating transport, this electric transport method not only reduces mechanical friction loss, but also significantly improves the transport efficiency and controllability of particle flow. This unidirectional flow characteristic makes the system perform particularly well in long-distance transport missions, effectively avoiding the problem of reverse movement or stagnation of particles.

[0033] Compared with other existing studies, the technical solution provided by the present 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 existing in traditional electrode structures, but also has significant advantages in heat dissipation performance and equipment stability. Compared with traditional planar electrodes, the innovative design of the present invention makes the electric field more efficient, greatly prolongs 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 the work of lunar dust transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] Embodiment 10: This embodiment provides a computer program product, which is a computer program. When the computer program is executed, the method provided in embodiment 7 is implemented.

[0078] Implementation Method XI: Combination Figure 1-4This embodiment is described in detail by using specific examples to further describe the technical solution provided above. Specifically:

[0079] The lunar dust transport mechanism is responsible for transporting the small-size lunar dust obtained after processing by the screening machine to the test part of the lander in order to carry out relevant experiments. A simple transport surface is achieved by adding a wedge-shaped micro-surface structure to the array electrode plate. The particles are driven by applying an alternating voltage to the embedded electrodes, and with the assistance of the wedge-shaped micro-surface structure, the transport surface can transport lunar dust upward through the slope. However, the effective utilization rate of the electric field on this surface is too low. The electric field generated by the array electrode 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 transportation efficiency of the overall structure.

[0080] Therefore, a structural improvement is 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 a three-dimensional comb electrode 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 a 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] Compared with a simple splicing surface, the three-dimensional comb electrode 1 distribution method has the following advantages:

[0082] Efficient electric field distribution: The three-dimensional comb-shaped electrode 1 has excellent electric field distribution characteristics, which can reduce the local excessive electric field strength and avoid electrode breakdown or energy loss. This three-dimensional distribution makes the electric field distribution more optimized, which can ensure overall uniformity and achieve 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, thereby improving work efficiency and preventing performance degradation or failure caused by overheating.

[0084] Reduce leakage and loss: The design of the three-dimensional comb electrode 1 can effectively reduce the unevenness of the electric field and reduce the probability of leakage current. When combined with the wedge-shaped microstructure 2, it can also reduce energy loss by optimizing the surface effect, making the device more energy efficient.

[0085] The improved design of the three-dimensional comb electrode 1 combined with the wedge-shaped microstructure 2 can significantly improve the uniformity of the electric field distribution and the response sensitivity of the device, while also having better heat dissipation performance and mechanical stability. Its easy manufacturability and superior performance make this structure have wide application potential in the future.

[0086] The technical solution provided by the present invention is further described in detail above through several specific implementation modes in order to highlight the advantages and benefits of the technical solution provided by the present invention. However, the several specific implementation modes described above are not intended to be used as limitations on the present invention. Any reasonable modification and improvement of the present invention, combination of implementation modes and equivalent substitution within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
