An Instantaneously Triggered Spatial Non-cooperative Target Grasping Device

Abstract

The invention discloses an instantly-triggered spatial non-cooperative target grabbing and attaching device which comprises a cylinder, a circuit cabin box, an empennage, an automatic popup mechanism, a shroud, a cover buckle, a buffer piece and a body grabbing and attaching mechanism. The device adopts the body grabbing and attaching mechanism as a core, according to the principle, two-level non-cooperative target surface mechanical locking type attaching that auxiliary grabbing and attaching are adopted as the main part and drilling-in connecting reinforcing is adopted as the auxiliary part is adopted, an auxiliary grabbing and attaching mechanism in the body grabbing and attaching mechanism adopts two torsional springs as a power component, an auxiliary hook with barbs is adopted as an execution component, and the hook can be stabbed into the target surface skin after triggering is performed; the device is carried and launched by a spacecraft on-orbit launching platform, and the target surface is stably grabbed and attached through the three steps of preparation before launching, auxiliary grabbing and attaching and connecting fastening. Meanwhile, the instantly-triggered spatial non-cooperative target grabbing and attaching device has the advantages of being large in grabbing and attaching range, low in control precision requirement, simple and reliable in grabbing and attaching process and the like.

Description

[0001] Technical field [0002] The invention relates to a space grasping device, in particular to an instantaneously triggered space non-cooperative target grasping device, which belongs to the field of aerospace technology. Background technique [0003] Space non-cooperative target is a kind of space moving body that does not have a special docking capture port or cannot actively provide communication information to the tracking spacecraft itself, such as faulty spacecraft, invalidated satellites, and space debris. Space non-cooperative target docking capture technology has great development prospects and application value in both military and civilian use. In the military, the world’s major aerospace powers are currently committed to the development of space offensive and defensive technology and other related research, which seriously threatens my country’s space security. my country must vigorously develop space non-cooperative target docking and capture technology, and establ...

Problems solved by technology

[0005] Traditional pressure-sensitive adhesives (double-sided tape, etc.) and cold glue are greatly affected by the space temperature, and are prone to lose their bonding effect; suction cup adsorption is not easy to achieve in a vacuum environment; electromagnetic adsorption requires that the adsorption surface must be a magnetically conductive surface, and More energy and more complex control are required; electrostatic adsorption requires non-cooperating target surface materials to be charged, and this method has a small adsorption force and is prone to tip discharge under high-voltage electric fields; bionic adsorption requires smooth or semi-smooth adsorption surfaces and low adsorption force , easy to fall off
