Changeable curved-surface stage

The invention relates to a changeable curved-surface stage composed of a plurality of stage surface units which are mutually independent. The stage surface units comprise independent lifting adjustingdevices mounted below stage panels, and all the stage panels in an initial stage are arranged in parallel in the width direction, wherein gaps exist between the stage panels. The stage surface unitsare pulled by pulling ropes under driving of servo motors to achieve rising and falling movement, and meanwhile swinging sliding sleeves conduct adaptive swinging relative to fixed sliding sleeves toachieve the overall-changeable spatial curved-surface show formed by means of the method that the multiple stage panels are in different angles relative to the horizontal plane and mutually differentin height. The stage surface under the normal state is of a horizontal plane structure, and in need of plots, all the stage surface units can rise and fall in a progressive mode or partially rise andfall according to the preset procedures, so that the front-high and rear-low effect is achieved, or the slowly-protruding and slowly-sinking wavy fluctuating effect is achieved, the grand and magnificent scene effect is generated, the feel of gorgeous, dynamic and amazing is brought to audience, and the changeable curved-surface stage accords with the age dynamic aesthetic demand.
