AI Technical Summary

Technical Problem

When existing satellite communication antenna turntables are in orbit, the external optical components undergo thermal deformation due to alternating hot and cold temperatures, resulting in beam wavefront distortion and pointing errors. Furthermore, the adjustment range of traditional turntables is limited, making them difficult to use effectively in scenarios where communication targets are frequently switched.

Method used

A satellite laser communication turntable angle adjustment device was designed. The device can be rotated 180 degrees through a position adjustment mechanism. Combined with a cable winding and unwinding mechanism, it can achieve automatic cable management. A medium-sized aluminum-based silicon carbide composite material is used to reduce the difference in thermal expansion coefficient, ensuring the stability of the device and the neatness of the cables under extreme temperatures.

Benefits of technology

It improves the stability and flexibility of satellite laser communication equipment, reduces communication blind spots, enhances the practicality and reliability of the equipment, ensures the orderly management of cables, and avoids cable damage caused by thermal deformation and flipping.

Abstract

The application belongs to the technical field of rotary table adjustment, and discloses a satellite laser communication rotary table angle adjustment device, which comprises a base, a azimuth shaft is arranged above the base, an elevating shaft is rotatably connected to the top of the azimuth shaft, a laser communication device is fixedly connected to the end of the elevating shaft, and the cooperation of the structures such as the inner slide plate, the outer cover, the first fixing block and the second fixing block facilitates the dynamic adjustment of the gravity center of the rotary table bottom support with the overturning of the laser communication device. On the basis of the original rotation, the rotary table is additionally provided with the function of overturning the laser communication device by 180 degrees. Compared with the traditional manual dismounting of the chassis and replacement of the position, the device can effectively improve the adjustment flexibility and response speed. Meanwhile, the shaft sleeve can drive the synchronously moving of the externally fixed inner slide plate, the inner slide plate can slide and switch positions in the inner cavity of the outer cover plate, the gravity center can be synchronously adjusted, the force borne by the device before and after overturning is consistent, and dust can be prevented from entering the bottom sliding groove.
