Anti-recovery pin is made up of bearing pin, plunger, movable key seat, fixing key seat and spring, the two ends of bearing pin are fixedly installed plunger and fixing key seat respectively, bearing pin slides and is provided with movable key seat, spring housing is on bearing pin, two ends are touched with plunger and removable pin seated connection respectively, and movable key seat is fixedly installed on anti-recovery in pin mounting hole.
Transportation insurance pin 10 is made up of screw bolt and nut, and utilization is threaded and overcomes the thrust of stage clip 8 pairs of hatch doors generations.
There is bolt connection mechanical interface 13 base plate 3 both sides, for the mechanical connection of device and platform.
Push pedal 7 and bonnet 6 have circular hole, and circular hole size is greater than the outshot of satellite.
Push pedal 7 arranges journal stirrup on the limit of symmetry, and journal stirrup is spacing by door guard plate 2 on the direction of slip of push pedal 7, and journal stirrup does not affect the slip of push pedal 7 in device, but it exceeds door guard plate 2 opening portion, can be blocked further during motion by door guard plate 2.
Hatch door 1 is in closed condition time flat, before receiving unlock command, ensures that rocket hatch door 1 in transportation closes complete.Microsatellite slides along integral rail in device, four panels up and down designs cuboid and gives prominence to structure 11, forms satellite slide rail between two.
Hatch door 1 is provided with torsion spring in rotation direction, and torsion spring is the spring by turning round work, and after hatch door 1 is opened, torsion spring also needs certain predetermincd tension, ensures that hatch door reliably stays open state, and absorbs certain bounce.
Sliding at cube star is emitted through in journey, and hatch door 1 is subject to comparatively noticeable effort, easily strikes Launch Vehicle Platform, for preventing possible grazing, and design hatch door position limiting structure.Namely utilize the plane spacing preiection 12 at axle bed rear portion, door guard plate 2 bottom, hatch door 1 is when rotating, and lower flat can overlap with plane spacing preiection 12 convex plane, and then stops that hatch door 1 rotates further.For ensureing to stablize, design 4 planar projections, and the angle of convex plane and vertical direction is 30 degree, to ensure that hatch door 1 maximum rotation angle is 150 degree.
When hatch door 1 motion put in place thirty years of age side's star do not launch out completely time, for preventing hatch door 1 from turning round under effect of inertia, hitting a cube star, thus affecting its performance and motion, hatch door is counter recovers structure, as Fig. 9 ~ 11 in design.Anti-recovery door comprises the axle bed of hatch door 1 bottom setting and anti-recovery latch structure door, and the top of axle bed is provided with a flat limit, and remainder is arc; Anti-recovery pin is made up of bearing pin, plunger, movable key seat, fixing key seat and spring, the two ends of bearing pin are fixedly installed plunger and fixing key seat respectively, bearing pin slides and is provided with movable key seat, spring housing is on bearing pin, two ends are fixed with plunger and movable key seat respectively, and movable key seat is fixedly installed on anti-recovery in pin mounting hole.Utilize the rotary motion trace that rotation seat rotates around hatch door turning cylinder, namely when hatch door starts to open to the angle of rotating corresponding to flat limit, the flat edge position of rotation seat overlaps with the circular hole instead recovering to sell riding position, and the anti-pin that recovers is blocked, and spring is compressed, when hatch door turns over the angle corresponding to flat limit, rotation seat arch section no longer intercepts and instead recovers pin, and it is tangent to recover to sell mounting hole with anti-on baffle plate 2 all the time, and the anti-pin that recovers then stretches out under the action of the spring, block rotation seat, hatch door 1 cannot be replied.Now, to manual-lock door, only need pinch fixing key seat, the anti-pin that recovers outwards is pulled out.
Because main body frame inside needs protection cube satellite; have its structural strength, shock resistance requirement, thermal requirements and mechanical requirements etc. and strictly design, and need through a series of ground validation test such as key player on a team's vibration, random vibration, impact, thermal cycle.In addition, spring device, release mechanism etc. are all be attached on main body frame, which again increases the complexity of main structure design, so require very high for the safety factor, reliability index etc. of main structure design.
Spring device mainly comprises a push pedal 7 of launching satellite, stage clip 8 and two for opening the torsion spring of hatch door, is the power place after whole satellite-launching facility hatch door unlocks.Stage clip 8 is springs of pressurized work, ensure that speed that cube satellite launches away is in certain scope, and the acceleration/accel of ejection process satellite is in certain scope, and what ensure when satellite launches is stable.Torsion spring is the spring by turning round work, is that after tripper unlocks, after hatch door 1 is opened, torsion spring also needs certain predetermincd tension, ensures that hatch door reliably stays open state, and absorb certain bounce.
For preventing small satellite from running helter-skelter in carrier rocket flight process, its motion in feedway must be limited, because small satellite is in framed structure, therefore the degree of freedom in its x, y direction is limited by framework, and z direction, i.e. satellite direction of ejection, need other measures.The mode that the present invention adopts stage clip 8 and hatch door jointly to limit, when designing stage clip 8, just consider microsatellite degree of freedom problem, namely after small satellite is placed into feedway, stage clip 8 is crushed to death substantially, then in hatch door 1 rear design raised platforms, when hatch door 1 is closed, further compression press spring 8, namely makes stage clip 8 solid height+microsatellite length+hatch door 1 inner overall length of projection thickness=feedway behind, realizes the degree of freedom restriction of microsatellite in emission process with this.
For existing satellite release gear, the surperficial length and width of push pedal 7 are consistent with microsatellite cross section length and width, when microsatellite is released by stage clip 8 completely, push pedal 7 also may be deviate under effect of inertia, causes certain influence, and therefore the present invention designs push pedal journal stirrup, prop up ear portions and exceed door guard plate 2 opening, namely, when push pedal 7 moves to hatch door 1, an ear portions can be blocked by door guard plate 2, and such push pedal 7 just cannot deviate from this device.
Release mechanism, primarily of sucker electromagnet 9 and electromagnet adsorption piece composition, controls the opening and closing of hatch door.Release mechanism is controlled by control circuit, before receiving unlock command, ensures the locking of hatch door failure-free; When receiving unlock command, after electromagnet 9 is energized, magnetic force is eliminated, and reliably remove the restriction to hatch door 1, unlocking manner is simple and reliable.
For increasing this device applicability, when designing push pedal 7 and bonnet 6, leaving circular hole respectively, being suitable for 3U+ series cube star to make this device.A 3U+ series cube star increases partial devices, as camera lens etc. at afterbody on original Unit 3 cube satellite-based plinth.
At base plate 3 both sides design bolt connection mechanical interface 13, refer to that the bolt of the some M6 of satellite-launching facility is fixed together with delivery erecting stage, structure is outstanding is convenient to Assembly &Disassembly, for ensureing to stablize, designs 8 interfaces altogether.Bolt connection mechanical interface 13 needs to make that device can be stable is fixed on delivery erecting stage, the mechanical requirements such as proof strength, antidetonation.
