Locking and releasing device for satellite and rocket separation

Abstract

A locking and releasing device for satellite and rocket separation relates to the technical field of satellite and rocket separation of small satellites. The locking and releasing device comprises a baseplate, connecting seats, clamping jaws and connecting rods, wherein a rotary shaft is arranged in the middle of the baseplate; a rotary block is arranged on the rotary shaft on the upper side of the baseplate; the at least three connecting seats are arranged on the baseplate; a hinged frame is arranged on each connecting seat; the L-shaped platy clamping jaws are arranged on the hinged frames in an inverted manner; a clamping groove is formed in the upper arm of each clamping jaw; a clamping head is arranged at one end of each connecting rod; a locking and releasing swing rod is arranged between each connecting seat and the corresponding rotary block; the middle of each locking and releasing swing rod is hinged to the baseplate; one end of each locking and releasing swing rod is hinged to the rotary block, and the other end of each locking and releasing swing rod is propped against the side arm of the corresponding clamping jaw; a release torsional spring is arranged on the rotary shaft; one end of the release torsional spring is fixed on the baseplate, and the other end of the release torsional spring is fixed on the rotary block; a positioning lock hole is formed in the rotary shaft on the lower side of the baseplate; and a push-and-pull electromagnet matched with the positioning lock hole is arranged on the baseplate. The locking and releasing device has the advantages of simple structure, small size, light weight, high reliability and the like.

Description

technical field [0001] The invention relates to the technical field of satellite-rocket separation for small satellites, and in detail relates to a locking and releasing device for satellite-rocket separation with simple structure, small volume, light weight and high reliability. Background technique [0002] We know that the separation of satellites and rockets, in a broad sense, is the separation process of a spacecraft or a satellite from a launch vehicle after it leaves the range of gravity of the earth. The locking release device is a device that realizes the separation function of the satellite and rocket. It has been widely used in aerospace missions. It can provide pre-tightening force for aerospace accessories so that they will not loosen and fall off during the launch process, and allow them to reach the target orbit. position when detached release.

AI Technical Summary

Problems solved by technology

[0003] The existing star-rocket separation system mainly consists of several typical combination methods such as tapes, springs, explosive bolts, and reverse thrust rockets. At present, most of the traditional star-rocket separation devices are pyrotechnic devices and explosive bolts, which will produce explosions during the release process. Large impact, serious pollution, high cost of pyrotechnics experiments and difficult transportation and storage, and with the development of small satellite and cube star technology, the traditional satellite-rocket separation device is difficult to apply to the launch of small satellites due to its inherent shortcomings
