Folding air-inflation type wind energy parasail device with center bracket

Abstract

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.

Description

technical field [0001] The invention relates to a retractable inflatable wind energy parasail device with a central support which utilizes ocean wind energy as the ship's sailing power, and belongs to the technical field of ship power and wind energy utilization. Background technique [0002] Most of today's energy sources are fossil fuels: coal, oil, and natural gas. At current rates of use, the remaining known coal deposits will be used up in about 200 years, while oil and gas will be used up in less than 100 years. do. Fossil fuels cause a lot of environmental pollution when used, including greenhouse gases that contribute to global warming. [0003] When the solar energy radiates to the surface of the earth, due to uneven heating, it will cause the flow of the atmosphere, coupled with the difference of seasons and the rotation of the earth, a regular monsoon will be formed on the ocean, and these winds provide endless wind for the navigation of ships. Energy and power....

Problems solved by technology

[0009] In the patent document "A Retractable Inflatable Wind Energy Umbrella Sail Device for Ship Navigation" (201010131058.1) (publication number 101786498A), the umbrella sail retractable device provided is a separate bracket, which can only play the role of suspension, and It is in a separated state from the parasail, and is connected by a non-stressed suspension cable. When the parasail is deployed, the parasail is inflated and only blown by the wind to release it. Without a tight cable connection, especially without a reverse cable, when there is a side wind or even a reverse wind, the parasail will be affected by the wind and its position will become very unstable; when it is recovered, only It is carried out by the air extraction of the umbrella sail, and then hung on the support of the retracting device. Similarly, it is also seriously affected by the wind, that is, the support of the retracting device has little effect on the stability of the umbrella sail. There are obvious deficiencies in the operability and stability of sail release and retraction
