Description

Technical Field

[0001] It relates to the technical field of space dust control and collection, and specifically to multi-channel electric field dust collection for lunar surface use. Background Art

[0002] With the continuous advancement of human deep space exploration missions, the moon, as an important frontier for extraterrestrial scientific research and resource development, has gradually received extensive attention. Due to the long-term exposure of the lunar surface to solar wind and micro-meteorite bombardment, a loose lunar dust layer covering the entire surface has formed. The particle size is mostly less than 100 microns, and it has obvious electrical conductivity, adsorbability and abrasiveness. During the Apollo program, astronauts often carried a large amount of highly adherent lunar dust when returning to the capsule. These dust particles caused wear on the joints of the spacesuits, attenuation of the performance of electronic equipment, and even discomfort in the astronauts' breathing, which was called "lunar hay fever". According to a NASA report, lunar dust has caused a drop in the efficiency of solar panels of up to 75%, seriously affecting the mission duration and payload safety.

[0003] In response to the pollution and harm problems caused by lunar dust, the existing technologies have proposed various treatment methods, including:

[0004] Mechanical cleaning devices: such as brushing devices, brush robots, etc., which rely on mechanical friction to sweep away the attached dust particles. This type of method has a simple structure, but it is easy to cause secondary dust suspension in a low-gravity environment, resulting in the resuspension of lunar dust;

[0005] Pneumatic suction systems: Use vacuum suction or high-pressure gas blowing to achieve dust stripping and absorption. However, the lunar surface is a near-vacuum environment, lacking air pressure support, resulting in extremely low suction efficiency;

[0006] Electrostatic repulsion technology: such as using a voltage-driven transparent conductive film (e.g. ITO film) to achieve surface dust removal, but it has poor adaptability and a limited range of action, and is not suitable for complex surfaces or non-planar structures;

[0007] Magnetic dust collection technology: It is only effective for iron-containing components, and cannot accurately control the collection particle size and direction, and is not suitable for in-situ resource collection scenarios with complex compositions.

[0008] In recent years, some research has begun to explore the use of an electrodynamic dust shield (EDS) for active dust migration, but there are still technical bottlenecks such as poor integration, high power consumption, and inaccurate direction selection control. Moreover, most of the solutions only focus on the cleaning function and lack the ability to collect and screen samples, making it difficult to support the requirements for lunar dust resource utilization.

[0009] In summary, the existing technologies generally have the following technical problems:

[0010] Lack of a lunar dust migration mechanism with strong controllability and a large range of action;

[0011] The integrated operation of cleaning and collection cannot be achieved;

[0012] The equipment system has insufficient adaptability to the complex terrain and extreme environment (such as low temperature, radiation) on the lunar surface;

[0013] There is a lack of a mechanism for lunar dust classification, guidance, and storage to support in-situ resource utilization (ISRU).

[0014] Therefore, there is an urgent need for an electric field dust collection device that can efficiently drive the directional migration of lunar dust, achieve automated cleaning and classification collection, so as to break through the key bottlenecks in current lunar dust governance and improve the stability and continuous operation ability of deep space exploration missions. Summary of the Invention

[0015] To solve the technical defects existing in the prior art, such as the lack of a large-scale lunar dust migration mechanism in lunar dust cleaning work, the failure to achieve the integration of cleaning and collection, and the insufficient adaptability of the system to the lunar surface, the technical solution provided by the present invention is as follows:

[0017] The multi-phase electrode plate is arranged in a three-phase layout, and is used to form an adjustable rotating electric field in the dust collection channel to drive lunar dust particles to migrate directionally into the collection bin;

[0018] The flexible insulating sleeve is arranged outside the electrode plate for electric field shielding;

[0019] The circuit system is used to control the electrical signal parameters of the electrode plate.

[0020] Furthermore, a preferred embodiment is provided, where there is at least one dust collection channel.

[0021] Furthermore, a preferred embodiment is provided, where the axis of the dust collection channel is parallel to the axis of the dust collection pipeline.

[0022] Furthermore, a preferred embodiment is provided, where the collection bin is provided with a sample grading and storage structure for classifying and storing the collected lunar dust according to the particle size of the dust particles.

[0023] Based on the same inventive concept, the present invention also provides a multi-channel electric field dust collection and removal equipment for the lunar surface, comprising: the above-mentioned device, and a handle arranged on the device.

[0024] Based on the same inventive concept, the present invention further provides a multi-channel electric field dust collection vehicle for lunar surface use, including: a lunar surface walking vehicle body, on which the above-mentioned device and a robotic arm for driving the dust collection pipeline to adjust its spatial position are provided.

[0025] Based on the same inventive concept, the present invention further provides a multi-channel electric field dust collection method for lunar surface use, which is implemented based on the above-mentioned device and includes:

[0026] The step of collecting the lunar dust concentration, electrode state and environmental electric field information in the dust collection channel;

[0027] The step of judging the working mode according to the lunar dust concentration, electrode state and environmental electric field information;

[0028] The step of adjusting the frequency and amplitude of the electrode signal according to the current working mode to form a rotating electric field for driving the migration of lunar dust;

[0029] The step of adjusting the electric field parameters based on real-time feedback.

[0030] Based on the same inventive concept, the present invention further provides a computer storage medium for storing a computer program, and when the computer program is read by a computer, the computer executes the above-mentioned method.

[0031] Based on the same inventive concept, the present invention further provides a computer, including a processor and a storage medium, and when the processor reads the computer program stored in the storage medium, the computer executes the above-mentioned method.

[0032] Based on the same inventive concept, the present invention further provides a computer program product, which is a computer program, and when the computer program is executed, the above-mentioned method is implemented.

[0033] Compared with the prior art, the beneficial effects of the technical solution provided by the present invention are as follows:

[0034] This solution adopts a three-phase electrode array structure. By setting multiple electrode plates with a phase difference of 120°, a continuously changing electric field direction and intensity are formed in the dust collection channel, so as to drive the charged lunar dust particles to achieve directional migration. Compared with the traditional electrostatic dust removal film, this method can achieve precise control in three-dimensional space, significantly expanding the action range and efficiency of the electric field, improving the adaptability to lunar dust of different particle sizes, and avoiding the problem of dust particle retention caused by the single direction of the traditional two-dimensional electrode.

[0035] The device introduces a flexible insulating sleeve to wrap the multi-phase electrode, which not only ensures that the directional effect of the electric field is not interfered by the outside world, but also avoids the risk of electric shock to surrounding equipment and operators caused by the high-voltage electric field. Compared with the traditional bare electrode system without protection, this structure significantly enhances the electrical safety and structural stability of the system in the complex lunar environment and is suitable for long-term on-orbit missions and field operations.

[0036] The dust collection channel configured in the solution is independently arranged in the dust collection pipeline and cooperates with the three-phase electrode for the design of the dust particle migration path, so that the lunar dust is drawn into the channel by the electric field after entering the pipeline and finally converges into the collection bin. Different from the existing EDS system that only realizes dust particle repulsion, this design realizes the integrated treatment of "directional cleaning + automatic collection", effectively supporting the centralized storage and subsequent analysis of lunar dust samples.

[0037] The electrical control unit adopted by the system monitors the dust particle density on the surface of the electrode plate and environmental changes through sensors, and can automatically adjust the electric field frequency and intensity to realize the closed-loop feedback control of the cleaning process. Compared with the traditional manually controlled electric field system, this control method significantly improves the intelligent level and energy utilization efficiency of the lunar dust cleaning operation, and is especially suitable for the lunar rover platform that needs to operate autonomously for a long time.

[0038] This invention supports two operation modes: integrated automatic operation and hand-held active cleaning, which are respectively applied to the mobile operation of the lunar rover and the local operation tasks of astronauts. Compared with the existing system with a single function and a fixed deployment method, this mode switching ability greatly improves the versatility and deployment flexibility of the system, and is especially suitable for the dust removal needs in complex terrains or areas that require manual intervention.

[0039] It can be applied to lunar dust cleaning, sampling and in-situ resource utilization operations in lunar exploration missions. Description of the Drawings

[0064] Embodiment Eleven. In combination with Figures 1-4 This embodiment is described. This embodiment further describes the above-provided technical solution in detail and completely. Specifically:

[0065] A multi-channel electric field dust collection device applicable to the lunar surface can achieve efficient lunar dust cleaning and collection operations in a complex lunar surface environment. The device includes: a dust collection pipeline, a dust collection channel, a multi-phase electrode plate, a flexible insulating sleeve, a circuit system, a collection bin, a robotic arm, and a lunar rover platform.

[0066] Among them, the dust collection pipeline is a hollow tubular structure, and its main body is made of a lightweight and high-strength insulating material, which can resist the extreme temperature changes and radiation environment on the lunar surface. The outside of the pipeline is coated with an insulating layer to shield the electric field leakage and at the same time protect the internal components from external dust pollution.

[0067] One or more dust collection channels extending along the axial direction of the pipeline are arranged inside the dust collection pipeline. Each dust collection channel is an embedded structure and is used to construct a lunar dust migration path. The dust collection channels are integrally formed or modularly assembled with the pipeline structure, which is convenient for customized layout according to the width of the cleaning target area and the dust particle density, thereby improving the dust collection flux and operation efficiency of the entire system.

[0068] The multi-phase electrode plates are arranged around the inner wall of each dust collection channel, and their arrangement adopts a three-phase distribution method. There is a fixed phase difference between the driving electrical signals of adjacent electrodes. By applying a three-phase alternating current signal, the electrode system can establish a rotating electric field that changes with time inside the channel, enabling the charged lunar dust particles to migrate along a predetermined direction. The electrode plates are made of conductive radiation-resistant materials, and their arrangement density, size structure, and spacing are designed and optimized according to the target dust particle size to achieve the maximum migration efficiency.

[0069] A flexible insulating sleeve is provided outside the electrode plate. This sleeve layer is composed of multiple layers of flexible polymer materials, has good electrical insulation ability and deformation adaptability, can conduct spatial shielding on the high-voltage electric field generated by the electrode, prevent electromagnetic leakage from affecting the lunar rover, astronauts, and surrounding equipment, and at the same time enhance the overall electrical safety of the system.

[0070] The end of the dust collection channel is connected to the collection bin. The collection bin is a sealed container, and a filter screen, a layered structure, and a sample storage area are arranged inside it, which can realize the physical isolation and directional sedimentation of lunar dust particles with different particle sizes. The material of the collection bin has the characteristics of dust prevention, high and low temperature resistance, and impact resistance, and is designed as a replaceable structure for sample recovery and replacement after the collection task is completed.

[0071] The entire system is controlled by a circuit system, which includes a three-phase signal generator, a voltage regulation unit, a feedback controller, and multiple groups of status sensors. The circuit system can monitor the dust particle density, the change of electric field strength, and the operation status of the equipment inside the channel in real time, and automatically adjust the working parameters of the electrodes to adapt to different operation requirements. The system supports remote scheduling through the main control module of the lunar rover, and a local adjustment interface can also be set in the astronaut's portable terminal to realize the manual fine adjustment function of the electric field.

[0072] This device can be installed on the lunar rover platform and can be driven by a robotic arm to achieve multi-degree-of-freedom arrangement, adapting to the automated cleaning operation of a large range of areas. During the cruise of the lunar rover, the automatic dust removal process can be triggered according to the dust deposition status monitored by the sensor. The device can also be in a handheld mode, operated by astronauts for local fine cleaning or scientific research sample collection, with good mobility and task flexibility.

[0073] In specific use, when it is detected that lunar dust accumulates or covers the surface of important instruments, the electrode system is immediately activated to generate a rotating electric field, which attracts and guides the surface dust particles into the dust collection channel and finally deposits them into the collection bin. This process has a high degree of automation, less manual intervention, and can flexibly adjust parameters according to the terrain environment, dust particle size and distribution characteristics to ensure the stability of the cleaning effect and the energy efficiency ratio of the system operation.

[0074] Through the above structural design and working mechanism, the multi-channel electric field dust collection device provided by the present invention is superior to the existing traditional lunar dust removal technologies in terms of lunar dust migration controllability, collection efficiency, system compatibility and intelligent level, and has good engineering practicability and popularization value.

[0075] Furthermore, its overall working process includes:

[0076] Initialization configuration

[0077] After the device is started, the electronic control system initializes each sensor and electrode module to obtain the current environmental parameters, including the lunar dust concentration in the dust collection channel, the external environmental electric field strength of the dust collection pipeline, the temperature state of the electrode plate and the operation history parameters.

[0078] Mode judgment and start decision

[0079] The system automatically judges whether the dust removal start threshold is reached according to the data fed back by the sensors. If in the automatic operation mode, the system will independently control the start of the electric field; if in the manual operation mode, the system will wait for the astronaut to input the corresponding parameters through the control terminal to start the dust collection.

[0080] Electric field excitation and lunar dust migration

[0081] The three-phase electrode plate starts to receive the three-phase signals sent by the electronic control system, and successively receives alternating current with a phase difference of 120°, forming a rotating electric field over time. This electric field is applied in the dust collection channel to apply a Coulomb force to the charged lunar dust particles and guide them to migrate along the channel towards the collection bin.

[0082] Dust particle collection and classified storage

[0083] The lunar dust particles are stably pushed to the end of the dust collection channel by the electric field force and deposited into the collection bin. The collection bin is provided with a filter layer or a particle size grading structure for classifying and storing lunar dust samples of different particle sizes or masses for subsequent scientific research or resource processing use.

[0084] Dynamic adjustment and feedback control

[0085] The system continuously monitors the dust collection effect and the change of dust particles, and dynamically adjusts the signal frequency, voltage amplitude or phase combination according to factors such as the actual collection efficiency, electrode temperature, and electrical signal stability to achieve closed-loop control and keep the system in the best working state.

[0086] In the logic controlled by electrical signals:

[0087] Three-phase electric field signal generation

[0088] The control unit generates three alternating current signals with a 120° phase difference through a three-phase signal generator to drive three groups of electrodes respectively. The signal frequency is usually controlled in the range of dozens of Hz to several kHz and can be adaptively adjusted by an algorithm to match the response characteristics of different lunar dust particle sizes.

[0089] Dynamic frequency and amplitude adjustment

[0090] According to parameters such as the lunar dust accumulation degree and the change of the electrode surface impedance feedback by the sensor, the electric control system calculates and adjusts the output frequency and voltage amplitude in real time. For example, in areas with a higher dust particle concentration, the system will increase the frequency to improve the cleaning rate; if the electrode temperature is detected to rise, the output voltage will be automatically reduced to prevent overheating.

[0091] Mode switching logic

[0092] In the automatic mode, the system autonomously adjusts the electric field completely based on data thresholds and environmental changes; in the manual mode, the electric signal parameters are input by the astronaut through a portable control terminal, and the electric control system converts the command parameters into corresponding drive signal combinations.

[0093] Fault tolerance and safety mechanism

[0094] A fault detection and emergency mechanism is embedded in the control logic. For example, if any group of signals in the three-phase electrodes is interrupted or unstable, the system will enter the protection state, automatically cut off the power, issue an alarm, and record an abnormal log through the diagnostic interface for subsequent inspection.

[0095] Embodiment 12. Through specific embodiments, the above-provided technical solutions are further described. Specifically:

[0096] This embodiment relates to a device for cleaning and collecting lunar dust on the lunar surface, specifically a cleaning and collecting method based on a three-phase electric field drive system (EDS). The device consists of a collection pipeline, a circuit system, and multiple electrode arrays, and can efficiently clean and collect lunar dust through the action of an electric field. And it can be selectively installed on a lunar rover and operated by an astronaut handheld.

[0097] The device of this embodiment mainly consists of the following parts:

[0098] Collection pipeline and collection unit: The pipeline for collecting lunar dust particles is made of high-strength and lightweight materials to ensure reliability in the lunar surface environment. The collection pipeline is slender to ensure a wide range of electric field effects. In addition, an insulating material is designed on the outer layer of the collection pipeline to prevent the electric field from affecting other equipment and ensure the safety of astronaut operations. The collection unit can be customized according to needs to adapt to different collection amounts and methods.

[0099] Three-phase electrode array: The electrode array is composed of multiple serially connected electrode components, and multiple electrodes are arranged on the electrode components, which can generate a three-phase electric field with adjustable intensity at different positions. By adjusting the intensity and frequency of the electric field, the electrodes can precisely control the movement direction and speed of lunar dust, realizing efficient lunar dust cleaning and collection.

[0100] Electrical control system: The system monitors the accumulation of lunar dust, the changes in the environmental electric field, and the operating status of the equipment in real time through sensors, and automatically adjusts the electric field intensity and frequency to ensure the maximization of the collection effect. The electrical control system can be remotely controlled through the operating system of the lunar rover or manually adjusted by the astronaut through a portable control device.

[0101] When lunar surface activities encounter the need for lunar dust cleaning and collection operations, the implementation mode of the lunar dust cleaning and collection device of this embodiment can be adjusted and expanded according to different mission requirements. The system can automatically adjust the intensity and direction of the electric field according to the accumulation amount of lunar dust and environmental changes. During the operation of the lunar rover, the sensors continuously monitor the accumulation of lunar dust in the vehicle body and the surrounding environment, and automatically start the cleaning process. This mode can effectively reduce the need for manual operation and improve the autonomy of the lunar rover during long-term missions. Astronauts can adjust the electric field parameters through a portable control device to precisely control the lunar dust cleaning and collection process. The manual mode is mainly applicable to specific areas that the lunar rover cannot reach or situations where the lunar dust accumulation is too concentrated and more precise operations are required. The device of this embodiment can collect samples for lunar dust composition analysis and scientific research purposes by guiding some lunar dust to a specific sampling container. The lunar dust sampling device can be separated from or integrated with the collection system for easy scientific research.

[0102] The beneficial effects are as follows:

[0103] High-efficiency lunar dust collection ability: Through the three-phase EDS system, the device can effectively drive the migration and collection of lunar dust particles in the extreme lunar environment. The precision of electric field control and the reasonable layout of the electrodes enable the device to have high adaptability under various lunar dust and terrain conditions.

[0104] Automation and Sustainability: The device of this embodiment can be closely integrated with the lunar rover or the equipment system of astronauts to achieve automatic cleaning and collection of lunar dust, reduce the need for manual intervention, and improve work efficiency. The system design takes into account the special environmental factors on the lunar surface, such as low gravity and extreme temperature differences, ensuring its stability and durability.

[0105] Low Energy Consumption and High Adaptability: The three-phase EDS system achieves a balance of low energy consumption and high efficiency through optimizing the electric field intensity and frequency regulation, meeting the working requirements under harsh conditions such as solar radiation and temperature changes in the lunar environment.

[0106] Fine Lunar Dust Treatment: By adjusting different electrode configurations and electric field intensities, this device can precisely regulate the behavior of lunar dust particles of different sizes and characteristics, ensuring efficient collection of lunar dust and avoiding interference with the surrounding environment.

[0107] The lunar dust cleaning and collection device based on the three-phase EDS system proposed in this embodiment can achieve efficient and automatic lunar dust cleaning and collection on the lunar surface through an innovative electric field driving principle and an efficient electrode array design, with important application prospects. This technology not only provides an effective lunar dust management solution for future lunar exploration missions but also can be extended to other space exploration and dust control fields in extraterrestrial environments.

[0108] The above further describes the technical solutions provided by the present invention through several specific embodiments to highlight the advantages and beneficial effects of the technical solutions provided by the present invention. However, the above several specific embodiments are not used as limitations on the present invention. Any reasonable modifications and improvements, combinations of embodiments, and equivalent replacements based on the spirit and principles of the present invention shall be included within the protection scope of the present invention.
