Embodiment Construction

[0017] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0018] Such as figure 1 and figure 2 As shown, the retractable space extension arm for satellite of the present invention is mainly composed of a mounting bracket 1, an elastic extension arm 2, a storage device 3, and a deployment control assembly 4. The installation bracket is installed on the top of the elastic extension arm, and the bottom of the elastic extension arm is installed on the storage On the device, the deployment control assembly is installed on the storage device and connected with the mounting bracket through a rope.

[0019] The elastic extension arm utilizes a telescopic coil spring as the core actuating element. When retracting, the telescopic spring is compressed into a spring coil. When unfolding, the elastic potential energy stored in the telescopic spring itself...

Abstract

The invention discloses a retractable spatial stretching arm for a satellite. The retractable spatial stretching arm mainly comprises a mounting bracket, an elastic stretching arm, a storage device and an unfolding control component, wherein the mounting bracket is mounted at the top end of the elastic stretching arm, the bottom of the elastic stretching arm is mounted on the storage device, and the unfolding control component is mounted on the storage device and is connected with the mounting bracket through a rope system. The retractable spatial stretching arm can realize the linear-direction controlled movement of the unfolding accessories and various load instruments of the satellite and is applicable to satellite loads, such as magnetometers, antennae and gravity gradient counterweights, and working statuses of the retractable spatial stretching arm comprise a folded lock status, an unfolding process and a fully-unfolded status, so that the application adaptability is wide.

Description

technical field [0001] The invention relates to an extension arm, in particular to a retractable space extension arm for a satellite. Background technique [0002] In order to solve the contradiction between the increasing weight of the spacecraft and the limitation of the size of the carrying envelope, the spacecraft needs to gather the load or stand-alone machine on the star during the active launch stage, and extend the load or stand-alone machine to the designated position after entering orbit. At the same time, on the basis of satisfying the load extension function, satellites have increasingly stringent requirements for the lightweight of each system and supporting parts, and put forward higher requirements for the envelope, storage ratio and weight of the extension device. Therefore, conventional deployment methods have been difficult to meet the above various requirements. Contents of the invention [0003] The technical problem to be solved by the present inventi...
