Microsatellite mobile cleaning shed

Abstract

The invention provides a microsatellite mobile cleaning shed, and relates to the field of satellite cleaning engineering. The microsatellite mobile cleaning shed comprises a cleaning shed body externally connected with an air shower; a source taking component is arranged on the inner side of the cleaning shed body; the top of the cleaning shed body is provided with a grid, and an FFU is arranged on the grid; a wall plate is arranged on the side face of the cleaning shed body, a plurality of test holes are formed in the wall plate, a PLC is arranged in the cleaning shed body, and a gear motor is arranged on the cleaning shed body; wheels are arranged at the bottom of the cleaning shed body and are in driving connection with the gear motor; and the PLC is electrically connected with the FFU and the source taking component. The functional requirements of being movable, detachable and detectable can be met, the wall plate meets the requirements of being transparent, visible, antistatic in inner wall and capable of meeting pollution control, the dust particle concentration can be monitored in real time, the air pressure can be adjusted according to the dust particle concentration, and the cleanliness grade of the microsatellite movable cleaning shed is superior to thousand grades.

Description

technical field [0001] The invention relates to the field of satellite clean engineering, in particular to a mobile clean booth for tiny satellites. Background technique [0002] Since satellites have anti-pollution requirements throughout the entire development life cycle, it is necessary to monitor and control the cleanliness of thousands of grades during the satellite general survey and final assembly process. In addition, satellites also need to monitor and control the cleanliness of their environment during their stay at the launch site. [0003] At present, there are generally two ways to create a clean environment for satellite development and assembly. One is to renovate or build a clean room, that is, to arrange corresponding heating channels, electrical and structures in accordance with the implementation requirements of GMP (Quality Management Standards). The 100,000-level cleanliness level is relatively easy to implement, but the establishment of a 100-level and...

AI Technical Summary

Problems solved by technology

[0005] 1. Although the traditional clean shed / clean room can be temporarily built for micro-satellites, the on-site construction period is long, which will affect the progress of micro-satellite research and development

[0006] 2. Since microsatellites need to involve multiple work areas from precision assembly to seismic testing, etc., however, traditional clean sheds / clean rooms cannot be moved, especially when re-calibration tests are required at the satellite launch base site, and multiple environmental inspections are required. Construction, construction technology requires synchronization and coordination, the implementation is more difficult, and the cost is higher
