An apparatus for adaptive wind-driven outdoor all-surrounding information display, the apparatus comprising, from bottom to top:
- a support means;
- a wind rotating means, comprising an annular baseplate and a plurality of sails disposed on the annular baseplate and used to capture wind energy and convert it to mechanical power;
- an information display means, comprising a plurality of information display devices each installed on the corresponding sail and comprised of at least one electronically controlled light-emitting display strip that is disposed on an outer elevation of the sail and used to distribute graphic and textual information, the support means and the wind rotating means cooperating with each other to achieve wind power generation and rotational speed control of the information display means;
- a motor/generator assembly, being installed on the support means and the wind rotating means and comprised of a plurality of working units that cooperate with each other to drive the wind rotating means to generate power or keep spinning, the motor/generator assembly turning the mechanical power of the wind rotating means to electric energy and storing the electric energy or converting the stored electric energy to mechanical power to maintain the rotation of the wind rotating means, thereby enabling adaptive control and adjustment of the mutual conversion relation and ratio between the mechanical power and the electric energy by switching between electric-operating and electric-generating modes or by controlling the number of active working units on the wind rotating means and the support means;
- and
- a control system, being coupled to each of the working units of the motor/generator assembly and to each of the electronically controlled light-emitting display strips, the control system being configured to control the cooperation among the working units on the wind rotating means and the support means thus enabling the wind rotating means and the support means to make adaptive adjustments under different wind conditions detected by the control system, wherein the control system automatically controls a mutual conversion ratio between the mechanical power and the electric energy so as to control the plurality of sails to operate within a predetermined rotational speed range, or instantaneously controls, according to the actual rotational speed or speed change of the wind rotating means under the drive of the natural wind, the lighting time, lighting duration, lighting interval, and displayed content of each electronically controlled light-emitting display strip or control part or all of the electronically controlled light-emitting display strips to turn active, so that dynamic trajectories of the displayed contents of all electronically controlled light-emitting display strips after they are lit and rotate are successively connected with each other thus creating an all-surrounding and continuous visible graphic and textual image.
