Separating and unlocking mechanism based on rotating electromagnet and separating and unlocking method

Abstract

The invention discloses a separating and unlocking mechanism based on a rotating electromagnet and a separating and unlocking method.The separating and unlocking mechanism comprises an upper cylinder, a lower cylinder, a locking device, a rotating device, a pushing device, a driving device, a limiting pin, a loading nut and a microswitch, the lower cylinder is sleeved with the upper cylinder, the rotating device is installed on the driving device and can rotate along with the driving device, and the pushing device is installed on the lower cylinder; the locking device transversely penetrates through the upper cylinder and the lower cylinder and abuts against the rotating device, the upper cylinder and the lower cylinder are locked together, when the driving device receives a satellite separation signal, the rotating device is driven by the driving device to rotate from the abutting position to the disengaging position, abutting between the rotating device and the locking device is relieved, the locking device is disengaged from the upper cylinder, and the upper cylinder and the lower cylinder are locked together. The upper cylinder and the lower cylinder are unlocked, the upper cylinder is ejected out under the action of the pushing device, and satellite-rocket separation is completed. The problems that a satellite-rocket separation mechanism is complex in structure, high in cost, large in envelope size, heavy in weight and the like are solved.

Description

technical field [0001] The invention relates to the field of star-arrow separation, in particular to a separation and unlocking mechanism and a separation and unlocking method based on a rotating electromagnet. Background technique [0002] The satellite-rocket separation is an important link in the satellite launch process. The separation mechanism provides a reliable connection before the satellite is released, unlocks the satellite in orbit, and releases the satellite safely at a predetermined release speed. [0003] In the prior art, the separation method of pyrotechnic products often adopts the belt type, point method, etc., and the separation method of non-pyrotechnic products often adopts the hot knife separation box structure (P-POD). The following disadvantages: the separation of pyrotechnics will produce a large impact, which is easy to cause damage to the single machine on the satellite, and bring certain damage to the satellite to be separated, especially the lau...
