Abstract

The invention discloses a compression release device and a spacecraft. The compressing and releasing device comprises a first mounting base part, a second mounting base part, a flexible connecting piece, an elastic piece and a hot knife assembly. The first mounting base part and the second mounting base part are fixedly connected with the flexible connecting piece respectively; the hot knife assembly is located between the first mounting base part and the second mounting base part and is movably arranged on the second mounting base part, and the flexible connecting piece is located on a moving path of the hot knife assembly; the first end of the elastic piece is connected with the second mounting base part, the second end of the elastic piece is connected with the hot knife assembly, and the elastic piece drives the hot knife assembly to abut against the flexible connecting piece; the hot knife assembly is an electric heating structural part, and the flexible connecting part is fused when the hot knife assembly is powered on. According to the device, the technical effects of simplifying the structure, reducing the impact load and reducing pollution can be achieved.

Description

technical field [0001] The invention relates to the technical field of compression release devices for spacecraft, in particular to a compression release device and a spacecraft. Background technique [0002] With the continuous development of space technology, the application scale of spacecraft (including artificial satellites, deep space probes, etc.) continues to expand. Locking and unlocking are the key technologies for spacecraft in-orbit flight, and are used to realize key actions such as solar wing deployment, antenna deployment, and payload release, and this technology needs to be realized based on a compression release device. [0003] The related compression and release devices are usually pyrotechnic devices, and its technology is relatively mature and stable, but there are obvious defects such as heavy device weight, large impact load, and serious explosion pollution. Contents of the invention [0004] The invention discloses a pressing and releasing device a...
