Embodiment Construction

[0046] A satellite payload sealing protective cover of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] As a specific application of the present invention, it can meet the sealing protection application requirements of solar X-ray and extreme ultraviolet imaging telescopes being developed in China. The present invention mainly completes the working goal of the protective cover through mechanical locking and electromagnetic unlocking. The device of the present invention is based on a mechanical locking strategy, which can increase the reliability of the system's on-orbit operation and reduce system costs; in addition, it can realize electromagnetic unlocking by using an electromagnetic switch and a lever mechanism, so that the control system is simple, the reliability is high, and there is no generation of space garbage .

Abstract

The invention provides a satellite effective load sealing protective shade, which comprises a butt joint and installation mechanism, a protective shade protection cover, a locking mechanism and a flicking mechanism, wherein the locking mechanism consists of components such as an electromagnetic switch, a lever mechanism, a stretched spring and the like, the sealing protective shade adopts an unlocking method of using the electromagnetic switch for providing the unlocking motive power, the protective shade protection cover is tightly locked to the preset position through the pulling force of the stretched spring arranged in the locking mechanism during locking, and the protective shade is ensured to be tightly locked by the mechanical method. Through a method of electrifying the electromagnetic switch arranged in the locking mechanism during unlocking, the locking mechanism is unlocked through overcoming the stretching force of the stretched spring, and the sealing protective shade is opened under the effect of the flicking mechanism. The structure of the invention can protect the effective load internal components from being polluted by external environment, simultaneously protectthe internal low-intensity components from being impacted by external airflows in the sending process, and enhance the survival capability in the stress environment, and in addition, the invention has the advantages of simple structure, low cost, reusability, wide environmental temperature range and high reliability.

Description

technical field [0001] The invention relates to the field of space technology, in particular to a reusable satellite payload sealing protective cover structure. Background technique [0002] The protective cover is one of the key structures of the satellite's highly sensitive payload. Many complex and high-sensitivity imaging instruments are assembled and tested in a clean room in order to avoid contamination by external dust or other gas components. Contamination, it is necessary to add a sealed protective cover at the inlet port of the instrument. At the same time, some astronomical observation instruments have nanometer-thick film filters inside. In order to avoid impact damage caused by external airflow, it is also necessary to add a sealed protective cover to the front end. For example, Japan, the United States and the United Kingdom jointly developed the X-ray telescope (XRT) of the SOLAR-B space telescope satellite designed and manufactured for the study of the sola...
