Abstract

The invention relates to a separation and unlocking device, in particular to a hot knife type hook lock separation mechanism. It includes a lock hook release mechanism, a hot knife assembly, a fastening rope, a fastening rope guide sleeve, a rope pretension spring and a bottom plate, wherein at least three lock hook release mechanisms are evenly distributed on the bottom plate along the circumferential direction, and the rope pretension spring is arranged on The base plate and the two ends are respectively connected with the two ends of the fastening rope that surrounds the hook end of each lock hook release mechanism in the circumferential direction. The hot knife assembly is arranged on the base plate and is located at a position opposite to the rope pretension spring , for fusing fastening ropes. A fastening rope guide sleeve for guiding the fastening rope is arranged on the bottom plate. The invention adopts a low-impact, pollution-free non-pyrotechnic unlocking device, that is, a hot knife-type unlocking mechanism. Because there is no burning or explosion of gunpowder during the release process, it has no impact, no pollution, good safety, and can be used during ground testing. Reusable and other advantages.

Description

technical field [0001] The invention relates to a separation and unlocking device, in particular to a hot knife type hook lock separation mechanism. Background technique [0002] In the field of spacecraft launch technology, separation devices occupy an important position. As a key component in the launch phase of a spacecraft, the separation device directly affects whether the space mission can be successfully completed. The traditional pyrotechnic separation device has a large separation load, which has potential adverse effects on the spacecraft. In view of this disadvantage, it is urgent to develop a new type of separation device, which has the characteristics of small separation load, large load, less energy required and controllable speed. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a hot knife type hook lock separation mechanism. The mechanism is stable, reliable and low-cost, and can be appl...
