本发明涉及月尘清洁技术领域，特别涉及一种可量化清洁月尘的装置及方法。The invention relates to the technical field of moon dust cleaning, in particular to a device and method for quantitatively cleaning moon dust.
背景技术Background technique
随着月球探测的深入开展，我国将会在月球开展长期的科学探测任务。然而，月尘将是在月球长期探测过程中必须面对的挑战。相关研究表明，月球表面悬浮着大量的月尘，开展月球探测的各个探测仪器直接暴露在月尘环境中。月尘粘附在探测器运动机构上会加剧部件磨损；附着在探测器传感器表面会造成科学测量结果失真；附着在太阳电磁阵上会降低供电效能；附着在光学镜片上会造成探测视线遮挡等等，月尘会给在月表活动的航天员和探测器带来诸多影响。With the in-depth development of lunar exploration, our country will carry out long-term scientific exploration missions on the moon. However, lunar dust will be a challenge that must be faced in the long-term exploration of the moon. Relevant studies have shown that there is a large amount of moon dust suspended on the surface of the moon, and various detection instruments for lunar exploration are directly exposed to the moon dust environment. The adhesion of moon dust to the moving mechanism of the probe will aggravate the wear and tear of components; the adhesion to the surface of the probe sensor will cause distortion of scientific measurement results; the adhesion to the solar electromagnetic array will reduce the power supply efficiency; Wait, moon dust will bring many influences to astronauts and probes active on the lunar surface.
目前，月尘清洁技术有刷子清扫法、表面充电法、机械振动法、电帘除尘法等。刷子清扫法除尘效率低，且易划伤设备；表面充电法能够排斥同性电荷的月尘，但会吸引中性或异性电荷的月尘；机械振动法是通过对附着月尘的表面施加一定频率和振幅的振动以抖落月尘，效率低且不适用已固定安装的探测设备；电帘除尘法是由交流的平行透明电极组成电帘，产生交变电场，将月尘沿垂直电极轴线方向向外运动，实现除尘，该技术适用于较大面积的设备，一般用于太阳电池阵，散热器等。At present, moon dust cleaning technologies include brush cleaning method, surface charging method, mechanical vibration method, electric curtain dust removal method and so on. The brush cleaning method has low dust removal efficiency and is easy to scratch the equipment; the surface charging method can repel moon dust with the same charge, but attracts the moon dust with neutral or opposite charges; the mechanical vibration method applies a certain frequency to the surface attached to the moon dust and amplitude vibration to shake off the moon dust, which is inefficient and not suitable for fixedly installed detection equipment; the electric curtain dust removal method is to form an electric curtain with alternating parallel transparent electrodes to generate an alternating electric field, and move the moon dust along the direction perpendicular to the axis of the electrode Move outward to achieve dust removal. This technology is suitable for equipment with a large area, generally used for solar cell arrays, radiators, etc.
上述除尘技术难以识别月尘的清洁度和完成度，对于不易采用上述除尘技术的设备来说，需要一种新的月尘清洁技术对表面附着的月尘进行量化清除。The above-mentioned dust removal technology is difficult to identify the cleanliness and completeness of the moon dust. For equipment that is not easy to use the above-mentioned dust removal technology, a new moon dust cleaning technology is needed to quantitatively remove the moon dust attached to the surface.

具体实施方式Detailed ways
下面结合附图和实施例对本发明的技术方案进行详细的说明，装置的组成图主要起到示意的作用，具体尺寸大小可根据实际应用场景进行适应性设计。The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. The composition diagram of the device is mainly for illustration, and the specific size can be adaptively designed according to the actual application scene.
实施例1Example 1
本发明实施例1给出了一种可量化清洁月尘的装置，包括安装底座、支撑杆、三维转动机构、电子束流清洁监测探头和控制电路等组成，如图1所示。支撑杆设计为圆柱中空结构，通信控制电缆通过中空支撑杆连接到控制电路。控制电路放置在安装底座内部，控制三维转动机构以及电子束流清洁和监测探头。三维转动机构设计为真空密封状态，避免月尘对自身的影响。电子束流清洁和监测探头设计为圆柱形，内部包括电子枪、月尘监测仪和激光测距仪。如图2所示，为电子束流清洁监测探头组成框图。由于在月球表面始终悬浮着月尘，清洁工作期间保护罩已处于打开状态，为抑制外部月尘的影响，将电子枪、月尘监测仪和激光测距仪均设计相对探头开口一定的距离。如图2所示，月尘监测仪、电子枪和激光测距仪距离探头开口处距离为d。Embodiment 1 of the present invention provides a device for quantitatively cleaning moon dust, including a mounting base, a support rod, a three-dimensional rotating mechanism, an electron beam cleaning monitoring probe, and a control circuit, as shown in FIG. 1 . The support rod is designed as a cylindrical hollow structure, and the communication control cable is connected to the control circuit through the hollow support rod. The control circuit is placed inside the installation base to control the three-dimensional rotating mechanism and the electron beam cleaning and monitoring probe. The three-dimensional rotating mechanism is designed in a vacuum-sealed state to avoid the influence of moon dust on itself. The electron beam cleaning and monitoring probe is designed in a cylindrical shape, and the interior includes an electron gun, a moon dust monitor and a laser range finder. As shown in Figure 2, it is a block diagram of the composition of the electron beam cleaning monitoring probe. Since moon dust is always suspended on the surface of the moon, the protective cover has been opened during the cleaning work. In order to suppress the influence of external moon dust, the electron gun, moon dust monitor and laser range finder are all designed to be at a certain distance from the probe opening. As shown in Figure 2, the distance between the moon dust monitor, electron gun and laser range finder from the opening of the probe is d.
清洁工作期间，在电子束流的轰击下，月尘从待清洁表面脱离，部分会进入探头。由于脱离月尘带负电，月尘监测仪壳体设计加载一定的正电位，电子枪和激光测距仪壳体设计加载一定的负电位。受到电子枪、月尘监测仪和激光测距仪壳体电位的作用，进入探头的月尘会被吸引集中到带正电的月尘监测仪，利于监测。同样，这些月尘会被月尘监测仪和激光测距仪的壳体负电排斥，防止月尘对电子枪和激光测距仪的污染。During the cleaning work, under the bombardment of the electron beam, the moon dust is detached from the surface to be cleaned, and part of it will enter the probe. Due to the negative charge from the moon dust, the shell of the moon dust monitor is designed to be loaded with a certain positive potential, and the shell of the electron gun and laser range finder is designed to be loaded with a certain negative potential. Affected by the potential of the shell of the electron gun, the moon dust monitor and the laser range finder, the moon dust entering the probe will be attracted and concentrated to the positively charged moon dust monitor, which is beneficial for monitoring. Similarly, these moon dust will be negatively repelled by the shells of the moon dust monitor and laser range finder, preventing the moon dust from polluting the electron gun and laser range finder.
电子束流清洁监测探头设计有保护盖，工作时保护盖打开；不工作时，保护盖关闭，以防止外部月尘对内部电子枪、月尘监测仪和激光测距仪的污染。如图3所示，为电子束流清洁监测探头示意图。The electron beam cleaning monitoring probe is designed with a protective cover, which is opened when working; when not working, the protective cover is closed to prevent external moon dust from polluting the internal electron gun, moon dust monitor and laser rangefinder. As shown in Fig. 3, it is a schematic diagram of the electron beam cleaning monitoring probe.
安装底座设计有安装支耳，方便该装置任意放置在适当的位置。支撑杆和三维转动机构可实现清洁和监测探头的俯仰、前后等全向转动和移动；激光测距仪负责监测清洁和监测探头距离待清洁表面的间距，以免碰撞到待测表面，造成损伤。月尘监测仪通过监测清洁过程中脱离设备表面的月尘数量，从而判断清洁的完成度。The installation base is designed with installation lugs, which is convenient for the device to be placed in an appropriate position. The support rod and the three-dimensional rotation mechanism can realize the pitch, front and rear, etc. omnidirectional rotation and movement of the cleaning and monitoring probe; the laser rangefinder is responsible for monitoring the distance between the cleaning and monitoring probe and the surface to be cleaned, so as to avoid collision with the surface to be tested and cause damage. The moon dust monitor monitors the amount of moon dust detached from the surface of the equipment during the cleaning process to judge the completion of the cleaning.
电子束流清洁和监测探头是该装置的核心部件，使用电子枪发射能量可控的电子束流，轰击待清洁表面，使得月尘脱离，从而实现清洁功能，使得本装置具有了非直接接触式的清洁形态，不触碰损伤待清洁表面。使用月尘监测仪实时监测月尘脱离数量，从而使得本装置具有了识别月尘清洁度和完成度的量化功能，能够将月尘清洁状态实时反馈给月表中控系统或操作人员。使用激光测距仪可精确控制探头与待清洁表面的极小距离，从而创造了量化监测的可行性条件。由于在月球表面始终悬浮着月尘，当探头与待清洁表面的距离过大时，将受到悬浮月尘的干扰，无法正确识别月尘的清洁度和完成度。The electron beam cleaning and monitoring probe is the core component of the device. The electron beam with controllable energy is emitted by the electron gun to bombard the surface to be cleaned, so that the moon dust is separated, so as to realize the cleaning function, which makes the device have non-direct contact Clean form, do not touch and damage the surface to be cleaned. The moon dust monitor is used to monitor the amount of moon dust in real time, so that the device has the quantitative function of identifying the cleanliness and completion of the moon dust, and can feed back the cleaning status of the moon dust to the central control system or operators of the lunar surface in real time. Using a laser range finder can precisely control the extremely small distance between the probe and the surface to be cleaned, thus creating the feasible conditions for quantitative monitoring. Since moon dust is always suspended on the surface of the moon, when the distance between the probe and the surface to be cleaned is too large, it will be interfered by the suspended moon dust, and the cleanliness and completeness of the moon dust cannot be correctly identified.
实施例2Example 2
本发明实施例2给出了一种可量化清洁月尘的装置及清洁月尘的方法。可量化清洁月尘装置的工作原理如图4所示，通过三维转动机构和激光测距仪的配合，将清洁和监测探头移动至距离待清洁设备表面10mm处。保持稳定，然后电子束流清洁监测探头发射一定能量的电子束流，轰击设备表面，使月尘脱离设备表面。脱离的月尘在月表呈散射状态，进入月尘监测仪。清洁过程中，月尘监测仪初始会监测到月尘数量激增。之后月尘数量下降，当月尘监测量恢复到清洁前时或接近零时，则表示该区域清洁完毕。然后，再由三维转动机构和激光测距仪配合，将清洁和监测探头移动至其余表面，进行清洁处理。Embodiment 2 of the present invention provides a device and a method for cleaning moon dust that can be quantified. The working principle of the quantifiable cleaning moon dust device is shown in Figure 4. Through the cooperation of the three-dimensional rotating mechanism and the laser rangefinder, the cleaning and monitoring probes are moved to a distance of 10mm from the surface of the equipment to be cleaned. Keep it stable, and then the electron beam cleans the monitoring probe and emits an electron beam with a certain energy to bombard the surface of the equipment, so that the moon dust is separated from the surface of the equipment. The detached moon dust is scattered on the lunar surface and enters the moon dust monitor. During the cleaning process, the lunar dust monitor will initially detect a surge in the amount of lunar dust. Afterwards, the amount of lunar dust decreased, and when the monitoring amount of lunar dust returned to before cleaning or was close to zero, it indicated that the area had been cleaned. Then, with the cooperation of the three-dimensional rotating mechanism and the laser rangefinder, the cleaning and monitoring probes are moved to the remaining surfaces for cleaning.
由于利用电子束流的非直接接触式清洁形态、激光测距仪的精确距离控制以及三维转动机构，本发明装置在实际清洁时，对于待清除设备表面不限于图4中所示的半球形，可适用于圆形，平板形、异形等多种表面。Due to the use of the indirect contact cleaning form of the electron beam, the precise distance control of the laser range finder, and the three-dimensional rotation mechanism, the device of the present invention is not limited to the hemispherical shape shown in Figure 4 for the surface of the equipment to be cleaned during actual cleaning. It can be applied to various surfaces such as round, flat, special-shaped and so on.
最后所应说明的是，以上实施例仅用以说明本发明的技术方案而非限制。尽管参照实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，对本发明的技术方案进行修改或者等同替换，都不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than limit them. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent replacements to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and all of them should be included in the scope of the present invention. within the scope of the claims.
