Description

Technical Field

[0001] The present invention relates to the field of lunar dust prevention and control technology, and specifically to the prevention and control of electric field creation when lunar dust is used in situ. Background Art

[0002] In-situ lunar dust resource utilization refers to the use of local resources on the moon to support space missions and the establishment of long-term lunar bases. By collecting, processing, and storing materials from the lunar surface, such as water ice and metals, oxygen, fuel, and building materials can be produced. In-situ lunar dust resource utilization aims to reduce dependence on Earth resources, lower space mission costs, improve mission sustainability, and provide the materials and energy needed for long-term lunar bases and deep space exploration. Lunar dust can be used as a building material for the construction of lunar bases and other infrastructure. Currently, mature technologies include melting lunar dust, which is piled into fixed molds and melted at high temperatures to make bricks and other building materials for the construction of radiation-proof and heat-insulating buildings.

[0003] However, there is a sheath electric field on the lunar surface, which causes the charged lunar dust particles to be subjected to an upward electric force. During the lunar dust spreading and compaction operation, two problems may arise: dust flying caused by the electric field force of the sheath electric field and large gaps between the powders due to the mutual repulsion of the charged lunar dust. Figure 2-4 These problems can cause cracks in the bricks, lowering various building material indicators and leading to failure of lunar structures, resulting in irreparable damage. Therefore, it is necessary to adopt certain technical means to resolve these problems, ensure the quality of lunar dust bricks, and increase the possibility of long-term human habitation on the moon. Summary of the Invention

[0004] To solve the technical problem in the prior art that the sheath electric field on the lunar surface causes gaps in the formed bricks during the lunar dust spreading and compaction operation, thereby reducing various indicators of the building materials and causing the failure of lunar surface buildings, the present invention provides the following technical solutions:

[0006] a comb-shaped electrode, serving as a negative electrode, comprising at least two finger-shaped electrodes arranged in parallel;

[0007] a columnar electrode, serving as a positive electrode, wherein the columnar electrodes are at least four;

[0008] The comb-shaped electrodes are embedded in the side walls of the roller, and the columnar electrodes are arranged in an array at the bottom of the melting mold.

[0009] A neutralizing electric field is formed to offset the electric field force of the sheath electric field, suppress dust emission and reduce the gap of charged lunar dust.

[0010] Furthermore, a preferred embodiment is provided, wherein the at least two parallel-arranged finger electrodes are arranged in parallel or nested with each other.

[0011] Furthermore, a preferred embodiment is provided, wherein the finger electrodes are used to provide uniform electric field distribution.

[0012] Furthermore, a preferred embodiment is provided, wherein the columnar electrodes are used to provide a local electric field.

[0014] Furthermore, a preferred embodiment is provided, wherein one end of the roller is provided with a dustproof end cover and a sealing ring.

[0015] Based on the same inventive concept, the present invention also provides a method for preventing and controlling the creation of an electric field during in-situ utilization of lunar dust. The method is implemented based on the module and includes:

[0016] The steps of collecting electric field simulation data in a preset experimental device in real time;

[0017] The step of optimizing the parameters of the comb-shaped electrodes and the columnar electrodes according to the simulation data.

[0020] 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.

[0021] Compared with the prior art, the technical solution provided by the present invention is beneficial in that:

[0022] This invention provides a method for preventing and controlling the creation of electric fields for in-situ utilization of lunar dust. By using a combination of comb-shaped and columnar electrodes, the method successfully offsets the sheath electric field on the lunar surface, suppressing dust emission. This effect is primarily due to the evenly distributed electric field of the comb-shaped electrodes and the strong localized electric field of the columnar electrodes. The combination of the two evenly covers a large area in both horizontal and vertical directions, resulting in a more uniform electric field distribution and significantly reducing dust emission.

[0023] This invention provides a method for controlling electric field generation during in-situ lunar dust utilization. By optimizing the electric field control strategy, the uniformity and intensity of the electric field are significantly improved. While the single electrode used in traditional solutions often cannot simultaneously meet the requirements of both large-area and localized high-intensity electric fields, the combination of comb-shaped and columnar electrodes significantly improves the flexibility and efficiency of the electric field by adjusting the geometric dimensions and arrangement. This allows for efficient operation at lower voltages, saving energy.

[0024] This invention provides a method for controlling the creation of an electric field during in-situ lunar dust utilization. By optimizing the electrode combination and electric field control strategy, it significantly reduces the gap between charged lunar dust and improves the quality and consistency of lunar dust-molded bricks. Compared to traditional methods without electric field optimization, the significantly reduced gap between charged lunar dust significantly enhances the mechanical strength and durability of the bricks, meeting the high standards required for lunar surface construction.

Through a developed and integrated control software system, it enables real-time monitoring and automatic adjustment of the electrode system. This allows for dynamic adjustment of electrode parameters based on actual operating conditions, further improving the system's stability and durability. Compared to existing methods of manually adjusting electrode parameters, this automated control not only improves work efficiency but also reduces errors caused by manual operation, making the entire system more intelligent and efficient.

[0026] The present invention provides a method for preventing and controlling the creation of an electric field during in-situ utilization of lunar dust, which is suitable for use in the work of preventing and controlling the creation of an electric field during in-situ utilization of lunar dust.

[0116] Implementation method 9: This implementation method provides a computer, including a processor and a storage medium. When the processor reads the computer program stored in the storage medium, the computer executes the method provided in implementation method 7.

[0117] 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.

[0118] Implementation Method 11: Combination Figure 1-6 This embodiment further describes the above technical solution in detail through specific examples, specifically:

[0119] To address the mutual repulsion between the sheath's electric field and the charged lunar dust, measures such as eliminating the lunar dust's potential and applying a reverse electric field are possible. However, eliminating the potential is difficult in the lunar environment, so a neutralizing electric field in the opposite direction of the sheath's electric field is used to counteract the sheath's electric field. Creating an electric field generally requires a pair of positive and negative electrodes, which come in various shapes, including needles, plates, combs, and columns.

[0120] The main contents of this embodiment are the selection of electrode combinations and the electric field layout scheme. The electrode combination selection adopts a combination of comb electrodes and columnar electrodes. The comb electrode is composed of a plurality of parallel arranged finger electrodes. These electrodes are usually spaced a certain distance apart, nested in each other or arranged in parallel, presenting a comb-like shape. The columnar electrode is an electrode with a unique structure. Its shape is columnar. It is usually used in applications requiring high electric field strength and complex electric field distribution. It is usually composed of multiple vertically arranged columnar structures. The electric field layout scheme uses the comb electrode surrounding the roller as the negative electrode and the array columnar electrode under the melting mold as the positive electrode.

[0121] Comb electrodes have significant advantages in creating electric fields, mainly in their ability to achieve uniform electric field distribution and high local electric field strength. Their structural design allows for precise control of the intensity and distribution of the electric field by adjusting the geometric dimensions, providing extremely high flexibility. In addition, comb electrodes can operate efficiently at lower voltages, contributing to energy conservation. Columnar electrodes can generate strong local electric fields at and around their tops. Compared with planar electrodes, columnar electrodes can create more complex and multi-dimensional electric field distributions in three-dimensional space. Columnar electrodes can also generate strong electric fields at lower voltages, thereby reducing power consumption. The combination of the two not only provides an electric field distribution in the vertical direction, but also provides a uniform and high-intensity electric field on the horizontal plane. The combination of columnar and comb electrodes can improve the mechanical stability and durability of the system, making it suitable for use in various environmental conditions.

[0122] The arrangement of multiple positive electrodes and one negative electrode generates a relatively uniform electric field over a large area, facilitating the uniform processing or control of charged lunar dust. This arrangement also increases the effective working area, improving processing speed and efficiency. The rolling negative electrode design helps reduce wear on the electrode surface, extending the life of the equipment.

[0123] like Figure 1 As shown, the compaction drum, or roller, serves as the load-bearing element, achieving rolling compaction through bearings and connectors. Dust-proof end caps and seals prevent charged moon dust from invading the bearings and causing them to fail. The connectors, through a screw mechanism, achieve translational movement across the compaction surface.

[0124] The polymer protective coating not only withstands the extreme temperature fluctuations and radiation environment on the lunar surface, but also protects the electrodes from direct wear and contamination from dust. The comb-shaped electrodes are made of a metal alloy, leveraging its excellent ductility, conductivity, and mechanical strength, making them suitable for long-term operation in the lunar environment.

[0125] When melting lunar dust, the dust is first spread into a mold. Then, an electric current is applied to the electrodes to create a neutralizing electric field. This neutralizing field counteracts the electric field of the sheath, suppressing dust emission. Because the neutralizing electric field is much stronger than the repulsive force between charged lunar dust particles, the gaps between them are reduced. The material is then melted at high temperatures to form bricks and other building materials that meet technical specifications.

[0126] 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.
