Abstract

The invention provides an energy closed-loop ultrahydrophobic electric curtain dust removal system for a space. The energy closed-loop ultrahydrophobic electric curtain dust removal system comprises a high-voltage solar cell module, a DC/AC converter, a relay switch boosting transformer, a comb-type transparent electric curtain and an ultrahydrophobic layer. According to the working principle, 300V high voltage provided by a high-voltage power generation module provides an over 1,000V high-voltage AC power supply to the comb-type electric curtain through DC/AC conversion and boosting; and an AC field is formed on the surface of the comb-type ultrahydrophobic electric curtain which is periodically spaced. The ultrahydrophobic layer greatly reduces the surface energy; and the adsorptivity of dust on the surface of a solar cell array is reduced, so that the dust is easily lifted under the action of the electric field and moves along the direction vertical to an electrode; the dust removal target is achieved; and the removal effect on large-grain dust or accumulated dust can also be achieved under the action of gravity, shake and the like. The dust removal system provided by the invention is high in dust removal efficiency, does not affect the optical property, can achieve energy closed loop and can be isolated from a spacecraft power system.

Description

一种应用于空间太阳电池阵的能量闭环超疏电帘除尘系统 One kind of energy applied to the closed space solar array power curtain dust removal system superoleophobic

技术领域 FIELD

[0001]本发明涉及光伏领域,具体涉及一种可应用于空间太阳能发电装置的能量闭环超疏电帘除尘系统。 [0001] The present invention relates to the photovoltaic field, particularly to a solar power generating device may be applied to the space of the electrical energy closed super-repellent curtain dust removal system.

背景技术 Background technique

[0002]地外深空探测领域,月球、火星表面都覆盖着一层很厚的土壤层,同时被吹起的尘埃在太阳照射及相互碰撞中会带上电荷,这些尘埃极易在深空探测器的太阳电池阵表面或者光学镜头表面吸附和积累,造成太阳电池阵功率下降以及拍照图像模糊。 [0002] outer space exploration of deep earth, the moon, Mars surfaces are covered with a thick layer of soil, blowing dust while being in the sun and will collide with each other electrically charged, the dust easily in deep space solar array lens surface or the optical surface of the detector absorption and accumulation, resulting in decreased solar array power and camera image blur. 在地面民用领域,环境污染的加剧光伏发电板、光学镜头、建筑玻璃等表面积累大量的灰尘,清洁难度大、周期长。 Civilian areas on the ground, increasing environmental pollution photovoltaic panels, optical lenses, architectural glass surface of the accumulation of large amounts of dust, large cleaning difficult, long cycle.

[0003] 1967年,Tatom等人提出了交变电场除尘方法,在尘埃易吸附的表面设计一层规则的交替帘状(或称梳状)电极,将交流电源加载在电帘两端时,表面就会形成规律的交变强电场。 [0003] 1967, Tatom et al proposed an alternating electric field dust removing method, the curtain-like dust alternately adsorbable surface design rule layer (or comb) electrodes, the AC power when an electrical load curtain ends, regular surface will form an alternating electric field is strong. 尘埃在强电场的极化下,受到电场力而得以摆脱黏附力和重力作用发生跃移运动。 Dust in a strong electric field polarization by the electric field force to get rid of the occurrence of adhesion and gravity saltation movement. 通过选择一定的电场频率,颗粒将被电场带离附着表面。 By selecting certain frequency electric field, an electric field away from the particles will be adhered to the surface. 该颗粒操纵方法无需机械装置,颗粒与电极无需接触,并适用于多种工况。 The method of manipulating particles without mechanical means, without contact with the electrode particles, and for a variety of conditions. 201110103339.0—种太阳能电池板除尘梳状电路及其工作系统公开了一种基于电帘除尘原理的太阳电池板除尘系统,但是该系统由于蓄电池可提供的电压有限,需要更复杂的变换电路,而且超过100V的母线电压将给航天电源系统带来巨大的风险,极大的限制了其在深空探测领域中应用,同时在地面应用中的还需要充电维护。 201110103339.0- species removal comb solar panel system is disclosed circuit and work removal system based on solar panels electric dust curtain principles, but the system is limited because the battery voltage can be provided, require more complex conversion circuit, and more than 100V bus voltage space power system will bring huge risks, greatly limiting its application in the field of deep space exploration, while ground application also needs to be charged for maintenance. 该发明设计的电帘除尘的不足还在于除尘后会有小颗粒的尘埃残留,对于深空探测中带电尘埃累聚后的颗粒达不到理想的除尘效果,而且对于地面应用中雨水过后附着的尘埃无法清除。 Insufficient electric dust curtain design of the invention will be further characterized by small particles of dust remaining after the removal, after the deep space for the charged dust particles accumulated poly dust removal effect is not ideal, but also for terrestrial applications after adhering rain dust can not be removed.

[0004]基于微纳凸起、多孔或者绒毛结构防水、防尘特性的超疏基除尘技术已经越来越多用于地面光伏发电板等领域,但是超疏除尘的劣势在于需要依赖重力、风,对颗粒较小的尘埃清除效果有限,无法胜任低重力且无风的深空探测任务,如月球探测中的除尘。 [0004] The micro-nano-based projections or villi waterproof porous, super-mercapto dustproof dust technology has been increasingly used in the field of terrestrial photovoltaic panels, but the disadvantage is that dust superhydrophobic rely gravity, wind, limited smaller particles of dust removal efficiency, low gravity and can not be qualified windless deep space exploration mission, such as lunar exploration in the dust.
