Technical field
The present invention relates to space netting capturing systems, more particularly, to a kind of Space Autonomous that achievable multiple target objects are arrested
Netting system and method.
Background technique
With the increase of mankind's solar-system operation, space debris environment is worsening.In order to protect valuable space orbit money
The safety of solar-system operation is improved in source, need to handle space junk, captures space junk and is drawn to other discarded
Track is effective method.Flexibility capture concept is that propose in recent years novel arrests mode, with flexible structures such as net or cloth
Covering, package object simultaneously form the assembly being reliably connected by flexible connection object (such as rope) and task spacecraft.As
The Typical Representative of flexible acquisition mode, space netting capture systems, which have, arrests between strong fault-tolerance, operation distance and aircraft
The advantages that coupling is weak has broad application prospects, and is one of the hot spot of space research in recent years.Traditional space netting
Capturing system proposes transmitting higher since the mass block being unfolded for netting does not have autonomous motor-driven function generally
Requirement, engagement range is general also shorter, and general a set of netting capturing system can only arrest an object, arrest efficiency compared with
It is low.
Summary of the invention
It is captured as background with extraterrestrial target object, capture high for launch requirements existing for Traditional Space netting capturing system
Apart from short and the problems such as arrest low efficiency, the purpose of the present invention is to provide a kind of Space Autonomous that achievable multiple target objects are arrested
Netting system and method drag space more piece netting using the restructural mechanism for having ejection separation with docking combination function, lead to
The Formation Configuration for crossing the minor structure of restructural mechanism change and combine the closing mechanism of every section netting realize the dehiscing of space netting,
It keeps and the operation such as closure of closing up.
In order to achieve the above object, the technical solution adopted by the present invention is that:
One, a kind of Space Autonomous multiple target objects arrest netting system:
Including mechanism, remote control locking mechanism, flexible 3 D netting and closing mechanism can be recombinated;Flexible 3 D netting mainly by
Successively it is connected first segment netting, the second section netting, third section netting, Section of four netting composition of arrangement, flexible 3 D netting
One end is tied as capture end, and the other end, which is connected to, can recombinate mechanism conduct capture arrival end, between adjacent segments netting
Closing mechanism is installed, is isolated or is connected to space in adjacent segments netting by closing mechanism.
When the netting system collapses, mechanism gathering and each closing mechanism can be recombinated against arrangement, then pass through remote control
Locking mechanism can recombinate mechanism and each closing mechanism banding, so that every section netting among flexible 3 D netting is received and is tied to
Between adjacent closing mechanism, a section netting of flexible 3 D netting capture end, which is received, ties up remote control locking mechanism, flexible 3 D rope
One section netting of net capture arrival end, which is received to be tied to, can recombinate mechanism;When the netting system is unfolded, mechanism opening can be recombinated, respectively
A closing mechanism separation arrangement, remote control locking mechanism, which is opened to be detached from, can recombinate mechanism and each closing mechanism, so that flexible 3 D
For every section netting free extension among netting between adjacent closing mechanism, flexible 3 D netting captures a section netting of end certainly
By extending between remote control locking mechanism and closing mechanism, a section netting free extension of flexible 3 D netting capture arrival end exists
It can recombinate between mechanism and closing mechanism.

Between adjacent closing mechanism, a section netting of flexible 3 D netting capture end, which is received, ties up remote control locking mechanism, flexible 3 D rope
One section netting of net capture arrival end, which is received to be tied to, can recombinate mechanism.
When the netting system is unfolded, mechanism opening, each closing mechanism separation arrangement can be recombinated, remote control locking mechanism is beaten
It opens and is not connected to that mechanism and each closing mechanism can be recombinated, so that every section netting free extension among flexible 3 D netting is adjacent
Between closing mechanism, flexible 3 D netting capture end a section netting free extension remote control locking mechanism and closing mechanism it
Between, a section netting free extension of flexible 3 D netting capture arrival end can recombinate between mechanism and closing mechanism.
Two, a kind of Space Autonomous multiple target objects arrest method, it is characterised in that:
1) before capture, can recombination structure be in recombination rounding state, flexible 3 D netting be in fold rounding state, it is soft
Property three-dimensional netting among every section netting compression be stored between each closing mechanism, flexible 3 D netting capture end a section
Netting compression is stored in remote control locking mechanism, and the section netting compression of flexible 3 D netting capture arrival end, which is stored in, can recombinate machine
Structure can recombinate mechanism by remote control locking mechanism and lock with each closing mechanism banding;
2) capture starts, and remote control locking mechanism, which is opened to be detached from, can recombinate mechanism and each closing mechanism, can recombination structure point
From expansion, flexible 3 D netting is freely launched into a space three-dimensional mesh bag, and each closing mechanism is in open communication state;
3) when capture carries out, after first capturing first aim object from Section of four netting, Section of four last netting entrance
The closing in lock unlock of the closing mechanism at place is opened, and two lateral closing in bars are under the elastic force effect of crossed strip respectively to rectangle frame
Middle part movement, two longitudinal closing in bars under the elastic force effect of longitudinal spring respectively to moving in the middle part of rectangle frame so that closing up
Mechanism intermediate space is stopped by four closing in bars, realizes the closing in closure of Section of four netting;
4) after capturing next object, the closing mechanism of third section netting and the second section netting inlet is successively pressed
It realizes that netting closes up according to step 3) same way to be closed, until first segment netting captures the last one object, can then weigh
Structure mechanism docking recombination, the closing in closure of first segment netting inlet, completes Space Autonomous multiple target objects and arrests.
