Abstract:
    The invention relates to a multi-beam feedback automatic switch device and driving device, in large-scale flexible antenna, wherein said switch 10 is formed by rotation platform 14, multi-beam feedback source 13, and hollow support bearing 21; the multi-beam feedback source 13 is uniformly distributed on the platform 14, to be supported by hollow support bearing 21, to rotate relative to the fine adjusting platform 9; then switching the feedback source at any frequency, to adjust it at the center of fine adjusting platform, to receive the radio signal at one signal focus and large frequency range; said driving device is formed by a servo motor 23, a flexible coupler 25, a speed reducer 26, a secondary coupler 27, a bearing base 28, and a coiler 29, while they are connected to the ground via bottom frame 30. The invention has wider frequency range, to be used in large flexible antenna and large radio telescope.
