Abstract

The invention relates to a non-pyrotechnic fusing connection separation device. The non-pyrotechnic fusing connection separation device is structurally characterized in that a valving nut A is mountedon a connection base, the shell I is sleeves the outer part of the split nut A and is connected with the connection base, and one end of a press rod is connected with the valving nut A; the valving nut A comprises a nut flap A I, a nut flap A II and a nut flap A III, wherein a ratchet wheel rope tightening mechanism is mounted in the nut flap A I, a fusing mechanism is mounted in the nut flap A II, a locking torsion spring and a fusing rope are sequentially wound around the outer part of the valving nut A, the fixing end of the locking torsion spring is fixedly mounted on the nut flap A III,the free end of the locking torsion spring is connected with one end of the fusing rope, and the other end of the fusing rope is connected with the ratchet wheel rope tightening mechanism. The non-pyrotechnic fusing connection separation device has the characteristics of small volume, light weight, large bearing capacity, energy conservation and environmental protection, and capable of repeatedlytesting and using.

Description

technical field [0001] The invention belongs to the field of aerospace, in particular to a novel non-pyrotechnic fusing connection separation device. Background technique [0002] Most of the mechanisms involved in the connection and separation of weaponry and aerospace equipment use pyrotechnic devices as drives. The pyrotechnic devices have poor safety, relatively large impact loads during the working process, and the system has a large structural mass and cannot be repeatedly tested for performance. Insufficient in areas such as polluting gases or debris. With the use of small satellites and high-precision micro-detection equipment, it is urgent to develop a new connection and separation mechanism with small size, light weight, large load, energy saving and environmental protection, low impact or even no impact, so as to adapt to the growing micro-weapon system and small-scale delivery. Rocket application requirements. Contents of the invention [0003] The technical ...
