Embodiment Construction

[0037] like Figures 1 to 6 As shown, the open locking and separating device of the pico-satellite of the present embodiment includes a separation base plate 1, four sleeves 2, four push rods 3, four separation springs 4, four pull rods 5, two baffle plates 6, Four extension springs 7, four hooks 8, two hot knife rests 9, two hot knives 10 and nylon rope 11. When the satellite 12 needs to be locked, the satellite 12 is put into the separation base plate 1, and the two pull rods 5 are tightened by the nylon rope 11, so that the pressing part 501 of the pull rod 5 is connected to the four bosses of the satellite 12 under the action of the extension spring. 1201 contact, satellite 12 is locked;

[0038] When the satellite 12 needs to be separated, the hot knife 10 is energized, and the nylon rope 11 is fused under the effect of the hot knife, and the pull bar 5 is disengaged from the satellite 12 under the effect of the extension spring 7 to realize the separation of the satelli...

Abstract

The invention discloses a pico-satellite open type locking and separating device comprising a separating bottom plate, a locking and separating module and a pushing module. The locking and separatingmodule comprises two sliding pieces, two cutting units, two elastic units, two sets of locking pieces and a locking rope, the two sliding pieces are symmetrically distributed and slidably mounted on the two sides of the separating bottom plate, and the two cutting units are mounted on the corresponding sliding pieces. The two elastic units connect the corresponding sliding pieces with the separating bottom plate. When the two sliding pieces are located on the locking position, the two elastic units deform to provide driving force for unlocking, and after the driving force is released, the twosliding pieces slide to the unlocking position where the two sliding pieces are away from each other. The two sets of locking pieces are mounted on the corresponding sliding pieces, and when the sliding pieces are located on the locking position, a satellite is pressed on the pushing module. The locking rope is simultaneously mounted on the cutting faces of the two cutting units in a wound mode and enables the two sliding pieces to slide to the locking position where the two sliding pieces are close to each other. The pico-satellite open type locking and separating device is simple in structure, convenient to mount, stable in work and low in development cost.

Description

technical field [0001] The invention relates to the technical field of aviation aircraft, in particular to an open locking and separating device for pico-satellites. Background technique [0002] The launch cost of a satellite is directly related to the weight of the whole star. The launch cost of a general satellite is 20,000 US dollars per kilogram. As a part of the whole star, the locking and separating device of the satellite occupies a considerable proportion in weight. How can it be effectively reduced? Weight has always been a concern of many experts and scholars. [0003] Conventional pico-satellites, especially Cubesat satellites, generally use a separation mechanism to fix the satellite in the cylindrical separation mechanism through the hatch, lock the hatch door through the titanium rod, and cut off the titanium rod through the fire attack device when separating, and the hatch door Simultaneously with opening, the satellite is released from the separation mechan...
