Problems solved by technology

If the mobile carrier just turns around and changes direction by 180° quickly at this time, the limit device may be triggered, and the star will be lost. After that, the antenna will restart to search for the star, and there will be no signal state for a period of time, which will affect the customer experience.
[0004] In addition, the rotation of each axis of the mobile communication antenna also involves the problem of the transmission cable. At present, the cable threading methods mainly include conductive slip rings or cable straight-through. The production process of conductive slip rings requires high requirements and costs The cost is high and it cannot be popularized; if the cable is passed through directly, the risk of cable breakage is high

Abstract

The invention discloses a rotating device for a mobile satellite antenna, which comprises an antenna frame, a base, a motor, a driving pulley and a driven pulley, the base is fixedly connected to the mobile carrier, the antenna frame is connected to the base in rotation, and the driving pulley is driven by the motor. The shafts are coaxial and fixedly connected, the driven pulley is set coaxially with the central axis of the antenna frame and the two are fixed. The winding post is covered with a spiral cable, and the antenna frame is fixed with a winding fixing seat. One end of the spiral cable is fixed on the winding fixing seat, and the other end of the spiral cable is fixed on the winding post. the top of. The advantage is to prevent the limit device from being triggered when the mobile carrier turns around quickly and changes direction by 180°, and the phenomenon of star loss occurs. In addition, the coil of the helical cable can shrink and spread freely during the rotation of the antenna frame to prevent the cable from being twisted. broken.

Description

technical field [0001] The invention relates to a mobile satellite antenna, in particular to a rotating device for the mobile satellite antenna. Background technique [0002] With the vigorous development of my country's satellite field, the application of satellite end stations is no longer limited to being fixed on the ground, but gradually develops towards mobile carriers. On mobile carriers, a moving-in-the-wire antenna must be used to ensure that the satellite antenna is always aligned with the satellite. Since the mobile carrier will be displaced during the driving process, the satellite antenna needs to be adjusted in time, and the direction adjustment needs to be limited to a certain range. Therefore, the mobile satellite needs to set a limit mechanism in the azimuth rotation device to limit its rotation range in the azimuth direction. [0003] The limit mechanism in the azimuth rotation device of the existing satellite antenna is usually a lever rotation device. Si...
