Abstract

The invention provides a flexible solar wing compaction and release device. The compaction and release device mainly consists of a driving end, a driven end and a support piece, wherein a driven piece is fixed with a movable plate; a roller on the driven piece rolls in a wedged compaction wheel of the driving end; and the movement of the movable plate to a fixed plate is realized through the height difference of the wedged compaction wheel to press a buffer material of a flexible wing to generate compaction force. After the compaction is in place, the movement trajectory of the wedged compaction wheel is an arc trajectory; and the roller of the driven end cannot automatically slide to reduce the compaction force. Before a solar wing is unfolded in orbit, the compaction and release device actively moves to release the fixed restraint between the movable plate and the fixed plate, so that the movable plate is smoothly unfolded under the driving of an unfolding mechanism. The device can repeatedly press and release the flexible solar wing, and is simple in structure and reliable in compaction. In addition, the support force is provided between the flexible solar wing and a cabin body by multiple support points, and the compaction force is provided by multiple locking points, so that the compaction and release device is high in bearing capacity.

Description

technical field [0001] The invention relates to a pressing and releasing device, in particular to a pressing and releasing device for a flexible solar wing. Background technique [0002] As a main form of space power supply for spacecraft, solar wings can no longer meet the tasks and energy requirements of large spacecraft due to the limitations of the volume and mass of rigid and semi-rigid solar wings with mature technology at this stage. Therefore, the volume of flexible solar wings can be The characteristics of small size, light weight, and high output power have become the main development direction of space large-scale solar wings. [0003] Due to the influence of launch envelope and mechanical load conditions, orbit change mechanical loads and return mechanical loads, the flexible solar wing needs to be pressed tightly on the cabin under the launch condition, orbit change condition and return condition; The fixed constraint of the rail and the cabin needs to be relea...
