Abstract

A dust collection device of a spiral electric curtain comprises a storage battery, a direct-current and alternating-current converter connected with the storage battery, a relay switch which is connected with the converter and can be closed, a transformer connected with the relay switch, and the spiral electric curtain. The spiral electric curtain comprises a plurality of electrodes and electrode connection points; the connection points are connected with multi-phase alternating-current electricity output by the transformer; and when the relay switch is closed, traveling waves of an alternating-current electric field are generated. The dust collection device can be applied to an optical lens or other optical systems of a round structure, can effectively solve the dust deposition problem of the surfaces of the optical systems, and the has the beneficial effects of being free of affecting the performance of the optical lens and free of damaging the surface structure of the optical system.

Description

[0001] technical field [0002] The invention relates to the field of dust removal, in particular to a spiral electric curtain dust removal device applicable to optical lenses. [0003] Background technique [0004] Since the surface of Mars and the moon are covered with a thick layer of dust, and the dust is charged, the optical lens on the Mars or lunar space lander is very easy to absorb dust, which will cause the lens to drop through the curtain and blur the image. In terms of civilian use, due to environmental pollution, optical lenses set up outdoors are more likely to be contaminated with dust, resulting in a decrease in image blur. [0005] In order to reduce the impact of dust on the optical system, research groups from various countries have proposed various methods for dust prevention and removal on the deposition surface, such as jet flow, oscillation, brushing, adding protective layer, surface charging and alternating electric field dust removal and many other ...
