Description

Technical Field

[0001] The invention relates to the field of satellite technology, and in particular to a multi-layer solar wing adjustment device suitable for a micro-satellite. Background Art

[0002] CubeSats were first proposed by California Institute of Technology and Stanford University in 1999. Their basic unit is a standard cubic module (1U) with a side length of 10 cm. The size of a microsatellite is usually expressed in multiples of 1U, such as 1U, 2U...12U, etc. Microsatellites stand out with their small size, light weight, low R&D cost, and short development cycle. The biggest difference from traditional satellites is that they adopt the concept of modular design and assembly. This design not only facilitates the testing and launch of satellites, but also ensures the continuity and maturity of technology, thereby effectively reducing costs. However, the development of microsatellites still faces a key problem - the restriction of energy on payload capacity. With the increasing power demand of payloads in technology verification and application of microsatellites, the existing solar panel installation method limits its photovoltaic production capacity and makes it difficult to meet the requirements of high-power payloads.

[0003] The photovoltaic capacity of solar panels is mainly affected by factors such as the effective working area of ​​the solar panels and the incident angle of sunlight. At present, the installation methods of micro-satellite solar panels are mainly divided into body-mounted surface-mounted, folding and unfolding, folding and unfolding single-axis directional, etc. The body-mounted solar panels in the existing patents are limited in the installation area due to their own surface area, resulting in insufficient power generation and unable to ensure the normal operation of the micro-satellite.

Through the action of the fixed cylinder 27 and the hydraulic box 227, the base plate 3 23 and the base plate 2 22 begin to turn over. Figure 1 The motion state shown moves to Fig.16 In the motion state shown, the positioning pin 251 on the second sub-plate 25 is just embedded in the positioning hole 1 243 of the first sub-plate 24 and the positioning hole 2 262 of the third sub-plate 26, so that the second sub-plate 25 lowers the second sub-plate 24 and the third sub-plate 26; Secondly, the sub-plate electromagnet 246 on the sub-plate 1 24 is turned on, generating a repulsive force on the push rod 28 disposed in the sub-plate hydraulic cylinder 1 245, so that the sub-plate 1 24 is turned over relative to the base plate 1 21, and the sub-plates 25 and 3 26 are also turned over accordingly. Fig.16 The motion state shown moves to Fig.17 The motion state shown; Then the electromagnet 216 on the base plate 21 is turned on, generating a repulsive force on the push rod 28 in the hydraulic cylinder 215, causing the base plate 21 to flip relative to the rotating shaft 29, driving the entire solar wing to move at the same time. Fig.17 The motion state shown moves to Fig.18 The motion state shown; Finally, when the solar wing 2 is unfolded, the electric cylinder 33 is started, and the electric cylinder 33 drives the gear 31 to rotate through the rack 32, so that the gear 31 drives the solar wings 2 on both sides to flip at the same time through the rotating shaft 29. The angle adjustment of the above-mentioned solar wing 2 can be adjusted in real time according to the different incident angles of sunlight, and the movement process of the entire device is completed at this time.
