Description

Technical Field

[0001] The invention relates to the technical field of space optical remote sensing, and in particular to a recyclable unlocking bracket assembly and adjustment device for an ultra-large aperture space optical remote sensing camera. Background Art

[0002] With the rapid development of large-aperture space payloads, the imaging capabilities of cameras are constantly increasing. As a connection and separation device between space remote sensing cameras and satellite platforms, unlockable camera brackets need to have good overall rigidity in the transport state to resist gravity overload during launch and orbit change. After reaching the designated orbit, the explosive bolts inside the bracket are detonated, the overall rigidity is destroyed, and the internal stress is eliminated. The satellite payload can adjust the camera posture under the movement of the flexible support. With the increase in the requirements for adjusting the camera posture, higher requirements are placed on the load-bearing capacity of the unlockable camera bracket, the movement gap after unlocking, and the control of the internal components of the bracket after unlocking. Therefore, the recyclable unlocking bracket of the ultra-large-aperture space optical remote sensing camera came into being.

[0003] When the bracket is locked, the elastic guide and space control system is in an elastic state. A large elastic potential energy is stored inside the system, which poses a great challenge to the installation and adjustment of the support. The existing installation and adjustment devices are difficult to complete the installation of the elastic state of the elastic guide and space control system, and cannot guarantee the overall rigidity and external interface accuracy of the bracket after installation.

[0004] Based on the above technical problems, the technical personnel in this field urgently need to develop a recyclable unlocking bracket installation device for an ultra-large aperture space optical remote sensing camera that can complete the installation of the elastic guide and elastic state of the space control system, ensure that multiple wedge blocks are evenly distributed along the circumferential direction, and ensure the external interface accuracy of the unlocking bracket and the overall stiffness requirements of the bracket.
