An on-orbit unlocking device for a space optical remote sensor installation support

Abstract

The invention relates to an on-rail unlocking device for a mounting support of a space optical remote sensor, which belongs to the field of space optics technology, and solves the problem of high processing, assembly and adjustment requirements, high precision requirements, long development cycle, high cost, large impulse and heavy weight in the prior art. 1. It takes up a lot of space, easily produces pollutants, and has potential safety hazards; the device includes the lower body of the mounting support used to connect with the satellite, the limit half-circle connected with the lower body of the mounting support, and the space optical remote sensor. The upper body of the installation support, the tension spring connected with the lower body of the installation support and the upper body of the installation support, the heat insulation pad contacted with the upper body of the installation support, and the telescopic ring for pressing the heat insulation pad. There are 2 limit semi-circular rings in total, which are connected to the lower body of the mounting support by means of hexagon socket screws. There are 8 pieces of heat insulation pads in total, which have telescopic function, and are sandwiched between the two telescopic rings and the upper body of the mounting support. The telescopic rings are made of memory alloy. Material, the non-contact surface of the telescopic ring has a heating plate, when heated, the telescopic ring shrinks.

Description

technical field [0001] The invention belongs to the technical field of space optics, and in particular relates to an on-rail unlocking device for a mounting support of a space optic remote sensor. Background technique [0002] As a high-precision spaceborne optical device, the space optical remote sensor is particularly sensitive to stress, and the ground installation and launch environment will inevitably introduce some stress, especially during the installation process of the space optical remote sensor and satellite, the introduction of assembly stress is the largest, so the design It is imperative to have a set of mounting support on-rail unlocking device. At present, the on-orbit unlocking device of space optical remote sensor mainly adopts pyrotechnic detonation method, which has the following disadvantages: [0003] 1) High requirements for processing and assembly, high precision requirements, and long development cycle. The structure of the pyrotechnic detonation d...
