Description

Technical Field

[0001] This invention relates to the field of satellite technology, and more specifically to a multi-layer solar array adjustment device suitable for microsatellites. Background Technology

[0002] The concept of a CubeSat was initially proposed in 1999 by the California Institute of Technology and Stanford University. Its basic unit is a standard cube module (1U) with sides of 10 centimeters. The size of CubeSats is typically expressed in multiples of 1U, such as 1U, 2U…12U, etc. CubeSats have distinguished themselves due to their small size, light weight, low R&D costs, and short development cycles. Their biggest difference from traditional satellites lies in their modular design and assembly. This design not only facilitates satellite testing and launch but also ensures technological continuity and maturity, thereby effectively reducing costs. However, the development of CubeSats still faces a key challenge—energy constraints on payload capacity. As the power demands of payloads in CubeSat technology verification and applications increase, existing solar panel installation methods limit photovoltaic capacity, making it difficult to meet the requirements of high-power payloads.

[0003] The photovoltaic power output of solar panels is mainly affected by factors such as the effective working area of ​​the solar panels and the angle of sunlight incidence. Currently, the installation methods for microsatellite solar panels are mainly divided into body-mounted surface-mounted, foldable deployment, and foldable deployment single-axis directional types. The body-mounted solar panels in existing patents, due to their limited surface area, result in a limited installation area for the solar panels, leading to insufficient power generation and inability to guarantee the normal operation of the microsatellite. Summary of the Invention

It employs a body-mounted surface-mount solar array installation method, allowing the double-layer solar array to be installed in a circular pattern around the surface of a microsatellite.

[0099] Working principle of this invention:

[0100] The initial state of the entire device is as follows Figure 1 As shown, once the microsatellite has successfully reached its space orbit, the solar panels 2 need to be deployed.

[0101] First, the two electromagnets 226 located on substrate 22 are activated, generating a repulsive force on the push rod 28 located in hydraulic cylinder 225. Through the action of the fixed cylinder 27 and hydraulic cylinder 227, substrate 3 23 and substrate 22 begin to flip, and... Figure 1 The motion state shown moves to, as Figure 16 As shown in the motion state, at this time, the positioning pin 251 on the secondary plate 25 is just embedded in the positioning hole 243 of the secondary plate 24 and the positioning hole 262 of the secondary plate 36, so that the secondary plate 25 performs a lower limit on the secondary plate 24 and the secondary plate 36.

[0102] Secondly, the sub-plate electromagnet 246 located on sub-plate 1 24 is activated, generating a repulsive force on the push rod 28 located in the sub-plate hydraulic cylinder 245, causing sub-plate 1 24 to flip relative to base plate 1 21. Sub-plate 2 25 and sub-plate 3 26 also flip accordingly. Figure 16 The motion state shown moves to, as Figure 17 The motion state shown;

[0103] Then, the electromagnet 216 on the substrate 21 is activated, generating a repulsive force on the push rod 28 located in the hydraulic cylinder 215, causing the substrate 21 to rotate relative to the rotating shaft 29, thus driving the entire solar array to move simultaneously. At this time, the entire device is... Figure 17 The motion state shown moves to, as Figure 18 The motion state shown;

[0104] Finally, after the solar array 2 is deployed, the electric cylinder 33 is activated. The electric cylinder 33 drives the gear 31 to rotate through the rack 32, so that the gear 31 drives the solar array 2 on both sides to rotate simultaneously through the rotating shaft 29. The angle adjustment of the solar array 2 can be adjusted in real time according to the different incident angles of sunlight. At this time, the entire movement process of the device is completed.
