Description
Technical Field
The invention belongs to the field of space debris cleaning, and particularly relates to a space rope releasing mechanism with adjustable damping.
Background
At present, except for the spacecraft which is still in normal use, the space still has dead man-made objects, namely space debris, remained in outer space. At present, the number of the space debris is as high as ten thousands, and the space debris threatens the safety of a working satellite at any moment, so that the space debris is not cleaned slowly. In the field of space debris cleaning, flexible capture off-rail is a novel off-rail technology. The space tug launches structures such as nets or cloth to wrap the target object and forms a reliably connected assembly with the space tug through the ropes, and then the space tug drags the target object to execute the task of off-track clearing.
In 3 months 1993, the small scale expandable deployment system (SEDS-1) test was developed in the United states. The aim was to verify the ability to achieve load return with a rope that does not consume fuel. The rope unfolding process in the test process is faster and smoother than expected, but the speed of the rope relative to the main star reaches 7m/s at the end of unfolding, so that a series of oscillations are caused, and a series of negative influences are brought to subsequent work. This problem is also considered when launching the net by a space tug.
Disclosure of Invention
The invention aims to provide a space rope releasing mechanism with adjustable damping, which realizes the function of adjusting the damping when a paying-off wheel rotates by adjusting the pressure on a damping sleeve, thereby ensuring that the paying-off wheel stops rotating when a rope is completely pulled out, and the relative speed of the rope is reduced to 0.
The technical solution for realizing the purpose of the invention is as follows: a space rope releasing mechanism with adjustable damping comprises a paying-off reel, a damping spring adjusting plug, a damping spring, a rope, a paying-off wheel, a damping sleeve and a bracket;
the pay-off wheel is arranged on the bracket through a pay-off shaft, the ropes are uniformly wound on the pay-off wheel, damping sleeves are sleeved on pay-off shafts outside two ends of the pay-off wheel, damping springs are sleeved on pay-off shafts outside the damping sleeves, and damping spring adjusting plugs are arranged on pay-off shafts outside the damping springs;
the position of the damping spring adjusting plug is adjusted, so that the damping spring is compressed to apply pressure to the damping sleeve, and the sliding friction force between the damping sleeve and the two side faces of the paying-off wheel meets the condition that the relative speed attenuation of the rope is 0 when the rope is completely pulled out from the paying-off wheel.
Furthermore, the damping spring adjusting plug is in threaded connection with the paying-off wheel shaft.
Further, the paying-off device further comprises a micro bearing, and the micro bearing is arranged between the paying-off wheel and the paying-off wheel shaft.
Further, the device also comprises a transmitter and a promotional device;
the bracket is fixed on the launcher through the shearing bolt, the push pin device is fixed on the launcher, the bracket is positioned on the push pin device and is not connected with the push pin device, initiating explosive devices are arranged in the push pin device, after the space tug tows a target to reach a target track, the initiating explosive devices in the push pin device are excited, the generated huge pressure acts on the bottom of the bracket, the shearing bolt is sheared off, the bracket and the paying-off wheel are separated from the space tug, and the target is released.
Further, the pushing pin device is fixedly arranged on the emitter through bolts.
Compared with the prior art, the invention has the remarkable advantages that:
this mechanism passes through damping spring and damping spring adjusting plug adjustment damping and sheathes in pressure, realizes the damped function when adjusting the actinobacillus wheel rotation, and then when guaranteeing that the rope is pulled out completely, actinobacillus wheel stall, and rope relative speed reduces to 0.
After the target is dragged to a desired track, the pin pushing device acts to cut off the shear screw, and the paying-off wheel is separated from the tugboat, so that the purpose of releasing the target is achieved.
According to the scheme, a special control system is not required to be added to control the rotation speed of the paying-off wheel, the overall structure is simple and reliable, and the safety factor of the space tug when the space tug executes a task is increased.

Detailed Description
The present invention is described in further detail below with reference to the attached drawing figures.
A space rope releasing mechanism with adjustable damping comprises a shear screw 1, a line shaft 2, a damping spring adjusting plug 3, a damping spring 4, a rope 5, a paying-off wheel 6, a damping sleeve 7, a bracket 8, a miniature bearing 10, a bolt 11 and a pushing pin device 12.
The rope 5 is wound on the pay-off wheel 6, one section of the rope is fixed on the fly net, and the other end of the rope is fixed on the pay-off wheel 6. When the net is launched and the line 5 is pulled, the speed of the line 5 relative to the space pushboat is at its maximum. The line 5 is drawn off, giving the reel 6 an initial speed of rotation. The damping sleeves 7 on the two sides of the paying-off wheel 6 generate sliding friction force to prevent the paying-off wheel 6 from rotating, and the paying-off wheel 6 starts to decelerate. By adjusting the magnitude of the sliding friction force generated by the damping sleeve 7, the paying-off wheel 6 can stop rotating when the rope 5 is completely pulled out, namely the relative speed of the rope is attenuated to 0.
The magnitude of the sliding friction force generated by the damping sleeve 7 can be adjusted by the following method: the sliding friction force generated by the damping sleeve 7 is in direct proportion to the pressure acting on the damping sleeve. The pressure on the damping sleeve 7 is provided by the damping spring 4. The degree to which the damping spring 4 is compressed is then adjusted by the damping spring adjuster plug 3. The damping spring adjusting plug 3 is connected with the paying-off wheel shaft 2 by using threads. The damping spring adjusting plug 3 is rotated in the positive direction and is close to the paying-off wheel 6, the damping spring 4 is compressed, the pressure acting on the damping sleeve 7 is increased, and the damping of the paying-off wheel 6 during rotation is increased. And the damping spring adjusting plug 3 is rotated in the opposite direction and is far away from the paying-off wheel 6, the damping spring 4 is released, the pressure acting on the damping sleeve 7 is reduced, and the damping when the paying-off wheel 6 rotates is reduced.
In the process of dragging a target off-track by a space tug, a bracket 8 of a paying-off wheel is fixed on a transmitter 9 by a shear bolt 1, and the normal work of the transmitter is ensured. After the target track is reached, the initiating explosive device in the pushing pin device 12 is excited, great pressure generated at the moment acts on the bottom of the bracket 8, the shearing bolt 1 can be sheared when the shearing bolt cannot bear the pressure generated by gunpowder gas, the bracket 8 and parts such as the paying-off wheel 6 are separated from the space tugboat, and the target is released.
