<p>A folding air-inflation type wind energy umbrella sail device with a central bracket comprises an extended folding central bracket (12), an air-inflation umbrella sail, an air charging/discharging device (16), an umbrella sail rope, a backward rope retractor, a bracket controller (35) and a support platform (21). The extended folding central bracket (12) has functions of retracting, adjusting of the elevation angle, and suspending the umbrella sail. The support platform (21) has the function of performing rotation angle adjustment with the wind direction. The central bracket (12) is further provided with a multi-stage structure capable of spreading and suspending multiple umbrella sails. Spreading and retracting of umbrella sails are implemented directly by charging and discharging of the umbrella sails and retracting of the backward rope retractor and the central bracket. The device has characteristics such as the stable umbrella sail position, fixed umbrella sail shape, large windage area, high windage position, high wind energy utilization, and simple retracting operation. The device has high reliability, so that the device can be used as a wind-driven device for ship navigation, and can also be used as a wind-energy supplementary power device for navigation of current fuel powered ships.</p> |
