Abstract
The utility model relates to an antenna auxiliary reflection surface system containing a swing adjusting mechanism. An antenna auxiliary reflection surface is employed as a load of a swing adjusting mechanism. The auxiliary reflection surface hanging frame fixed on the support leg of the antenna auxiliary reflection surface is employed as the support platform of the swing adjusting mechanism. The auxiliary reflection surface swing adjusting mechanism connects the auxiliary reflection surface hanging frame with the auxiliary reflection surface by a crank rocking bar mechanism in a specific installation way. The auxiliary reflection surface swing adjusting mechanism comprises six parts of a motor, a worm gear reducer, a crank, a connection rod, a rocking bar truss and an auxiliary reflection surface support arm. The antenna auxiliary reflection surface system is advantageous in that the antenna auxiliary reflection surface system has a unidirectional swing adjusting capability, ensures contact of moving components, is not easy to wear, has a fast response speed and high reliability, avoids reverse rotation of the crank rocking bar mechanism by utilization of the self-locking characteristic of the worm gear reducer so as to ensure stabilization of adjusting work of the auxiliary reflection surface, can achieve real-time adjusting of unidirectional reciprocating swing of the position and the posture of the antenna auxiliary reflection surface, and meets changes of antenna performances and directional tracking.
