Embodiment Construction

[0033] The lower end of the extension arm base 5 is fixed on the slope of the mechanism base 9 by screws, and the upper end is fixed on the slope of the support plate 1 by screws; the top cover 2 is fixed on the upper surface of the support plate 1 by screws; The side of the top cover 2; the lower protective plate 8 is fixed on the extension arm base 5 by screws. The swing rod 7 passes through the rectangular slot of the extension arm base 5 and is connected to the extension arm base 5 by the rotating shaft, so that it can rotate freely around the rotating shaft; the pressing plate presses one end of the swing rod 7 on the circular boss of the mechanism base 9 Above, the lower end of the pressing plate 12 passes through the through hole of the mechanism base 9, and a limiting hole is set; the limiting pin 13 passes through the limiting hole at the lower end of the pressing plate 12, thereby limiting the rotation of the fork 7; the torsion spring 14 is installed on the pendulum ...

Abstract

The invention discloses a rope net unfolding device based on a thin-wall type stretching arm, which is used for ontrack cleaning of space debris. The device does not need to be driven by external power, and a net body structure is driven to unfold by strain energy stored by the thin-wall type stretching arm, so as to capture the space debris. Through adoption of a thin-wall structure, the stretching arm has high flexibility and light weight, the stretching arm stretches out and contracts back to store strain energy and to enable the mechanism to achieve a high magnification ratio. Due to the design that the stretching arm drives the net body structure to unfold, the unfolding process of the net body structure has good controllability; and due to the design of a press plate and a limiting pin, the unfolding synchronism is ensured.

Description

technical field [0001] The invention relates to the field of space applications, in particular to a rope net deployment device based on a thin-walled extension arm. technical background [0002] With the increasing space activities of human beings, the threat of space debris to space vehicles is becoming more and more serious. Therefore, space debris removal has become a hot spot in space technology research at home and abroad. For space debris cleaning tasks, research institutions in various countries have proposed a variety of different solutions. For example, Tethers Unlimited of the United States proposed a plan to use an inflatable extension arm to drive the net structure to expand to capture space debris. GRASP device. [0003] The advantage of using the stretching arm to drive the network structure to expand and capture space debris is that not only can the network structure form a larger envelope surface, but also the limited stiffness of the stretching arm can be u...
