Turnover space-borne antenna locking releasing device

Abstract

The invention relates to a turnover satellite borne antenna locking releasing device which consists of a switchover piece, a rotor shaft, a torsional spring, a pressure plate, a locking lever, a limit cover, a spring cover, a spring, a locknut, a ball pad, a support and a cutter. The invention effectively transforms the impact force applied to the locking lever in cutting to the release power through the limit cover on the pressure plate, and the release power and the torsional force of the torsional spring act together, thereby increasing the separating speed between the pressure plate and the support and increasing the separating reliability. The exposed part of the locking lever under the pressure plate is shorter after the locking lever is cut, the turnover angle of the pressure plateis big, and the pressure plate is kept to be fixed after being in place under the moment action of the torsional spring so as to enable the pressure plate to keep a longer distance from the support, thereby ensuring the rotation reliability of the antenna; meanwhile, the invention has simple structure, therefore facilitating production and manufacture.

Description

technical field [0001] The invention relates to a locking and releasing device for a reversible space-borne antenna, in particular to a locking and releasing device for a space-borne continuous 360-degree rotating antenna, which is mainly used for satellite antennas. Background technique [0002] The continuous 360-degree rotating antenna is mainly composed of a reflector and a high-frequency box. The high-frequency box is used as the support structure of the reflector and connected to the rotating mechanism. The rotating mechanism drives the high-frequency box and then drives the antenna to perform continuous 360-degree scanning. [0003] At present, in the locking and releasing device used on satellite antennas, the two parts to be locked can move linearly up and down within a short distance. The traditional locking and releasing device is used to unlock and release the antenna and the pressure plate to move upward together, and finally complete the release. Separation act...

AI Technical Summary

Problems solved by technology

Since the continuous 360° rotating antenna has no upward movement function, not only the contact surface of the pressure plate and the support cannot be effectively separated after separation, but also the lowermost end of the cut-off locking rod cannot be pulled out of the support hole effectively, so the antenna cannot rotate freely, so adopt After the traditional device is released, the pressure plate cannot be effectively separated from the support, so that the antenna cannot rotate freely, so the traditional device cannot be applied to the locking and releasing of the continuous 360° rotating antenna
