Abstract

The invention relates to the field of geostationary satellite ground communications, and discloses a single-rod double-end lock-type locking device for an oscillating mirror type satellite laser communication terminal and a locking method of the single-rod double-end lock-type locking device, so as to solve the problems that the conventional locking device for an oscillating mirror type optical communication terminal is large in size, high in mass, and complicated in structure. The locking method comprises the steps that bolts penetrate through bolt holes in an oscillating mirror single-rod pressing plate to allow the oscillating mirror single-rod pressing plate to be fixed to the other side of an oscillating mirror mounting seat; a locking pin of each releasing device sequentially penetrates through a through hole in one oscillating mirror double-end pressing plate and a cylindrical groove in the oscillating mirror single-rod pressing plate, then the bolts penetrate through bolt holes in the two releasing devices and threaded holes in the tops of the oscillating mirror double-end pressing plates, so as to allow the releasing devices and the oscillating mirror single-rod pressing plate to be fixedly connected with the oscillating mirror double-end pressing plates; and the bolts penetrate through the threaded holes in the bottom ends of the oscillating mirror double-end pressing plates to allow the oscillating mirror double-end pressing plates to be fixed to the sides of upright columns of U-shaped racks, thereby realizing the effect of locking an oscillating mirror. The single-rod double-end lock-type locking device and the locking method are used for locking the oscillating mirror type satellite laser communication terminal.

Description

technical field [0001] The invention relates to a single-rod double-end locking type locking device and a locking method for a swing mirror satellite laser communication terminal. It belongs to the field of geosynchronous satellite-to-ground communication. Background technique [0002] The pendulous mirror optical communication terminal is a new type of optical communication terminal, which is used for geosynchronous satellite-to-ground communication, such as figure 1 shown. Considering the practical requirements of the satellite optical network, while ensuring the high communication data rate of the terminal > 5Gbps / s, the volume and quality of the terminal are also limited to a near-limit range. This requires that the mass of the locking device does not exceed 10% of the total mass of the terminal. [0003] A general locking device mainly includes a pressing plate, an unlocking mechanism and a locking seat. The structural forms of laser communication terminals are: per...
