The two ends of the other arc-shaped skeleton bar 206 are fixedly connected to the support vertical rod 207 by screws. At this time, the arc-shaped skeleton bar 206 is locked and installed through the second locking knob 208, which is convenient for the imaging light-shielding curtain 210 to remain taut between two adjacent support vertical rods 207. Moreover, the linearly arranged arc-shaped skeleton bars 206 can facilitate the shaping and support of the support vertical rod 207, and at the same time, it is convenient for folding when the support vertical rod 207 is stored. The conical light-shielding cover 101 and the multiple imaging light-shielding curtains 210 in the virtual-real display splicing component 203 can provide all-round shielding and protection for the scene platform.

[0027] Among them, the second splicing unit 205 is in the storage state of the imaging light-shielding curtain 210, and the first splicing unit 204 is in the unfolded state of the imaging light-shielding curtain 210. When broadcasting news, the announcer enters from the second splicing unit 205 and stands on the broadcasting stand 402. After turning on the power, the number of the second splicing units 205 is adjusted according to the news broadcasting scene to meet the amount of picture input of the news scene. The inclination angle of the swing mounting ring 112 is adjusted according to the height of the announcer. Specifically, the swing mounting ring 112 is swung and adjusted inside the rotation positioning ring 103. One end of the first locking knob 110 penetrates through the rotation positioning ring 103 and is threadedly connected to the swing mounting ring 112. The swing mounting ring 112 and the rotation positioning ring 103 are locked through the first locking knob 110, so as to facilitate the swing mounting ring 112 to drive the video camera 105 to adjust the inclination angle to meet the proportion of the announcer in the input picture.

The content of the news broadcast is supplemented and simulated through the projection screen, effectively enhancing the authenticity and richness of the news broadcast. By relatively adjusting the quantities of the first splicing unit 204 and the second splicing unit 205, it is convenient to adaptively adjust the scene ratio between the virtual picture and the news site; The electric push rod 302 is activated, such that under the support of the support base 301, the electric push rod 302 drives the positioning plug 303 to penetrate through the transmission connection ring 401 and the central mounting ring 501 and be connected to the transmission external gear ring 502 through inter-tooth meshing. The transmission motor 505 is activated, such that the transmission motor 505 drives the outer ring rotating base 107 to rotate on the upper end surface of the support base 301 through the transmission gear 506 and the transmission external gear ring 502. Furthermore, the outer ring rotating base 107 synchronously drives the transmission connection ring 401 and the announcer standing platform 402 to rotate through the positioning plug 303, realizing the synchronous rotation of the scene acquisition mechanism 1, the virtual-real combination mechanism 2, and the announcer, so as to facilitate the rotation and switching of the scene picture of the news site while keeping the video relay machine 105 relatively stationary with respect to the announcer, providing a wider range of scene views; By resetting the positioning plug 303 and separating it from the central mounting ring 501, when the transmission gear 506 drives the outer ring rotating base 107 to rotate through the transmission external gear ring 502 at this time, the outer ring rotating base 107 rotates relative to the transmission connection ring 401 through the four planetary gears 504. Furthermore, it is convenient for the video relay machine 105 to dynamically adjust the image acquisition angle of the announcer. By quickly assembling and moving the scene acquisition mechanism 1, the virtual-real combination mechanism 2, and the scene rotation platform 6, not only can news broadcasts with fixed virtual scenes be carried out indoors, but also news broadcasts with virtual-real combination can be carried out outdoors. The use is not restricted, and at the same time, different virtual scenes can be quickly switched without the need for cumbersome scene construction and disassembly work, improving the production efficiency.
