Abstract

The invention provides a space optical remote sensor installation support on-orbit unlocking device and belongs to the technical field of space optics. The problems that the requirements for machining, installation, adjustment and accuracy are high, a development period is long, cost is high, the impulse, the weight and the occupied space are large, pollutants are easily generated, and potential safety hazards exist in the prior art are solved. The device comprises a lower installation support body used for being connected with a satellite, semicircular limiting rings connected with the lower installation support body, an upper installation support body connected with a space optical remote sensor, an extension spring connected with the lower installation support body and the upper installation support body, thermal insulation pads making contact with the upper installation support body, and telescopic rings pressing the thermal insulation pads. The two semicircular limiting rings are connected with the lower installation support body through hexagon socket screws, the eight thermal insulation pads have the telescopic function and are clamped between the two telescopic rings and the upper installation support body, the telescopic rings are made of a memory alloy material, heating pads are arranged on the non-contact faces of the telescopic rings, and the telescopic rings shrink when being heated.

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...
