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

Abstract

The invention provides a folding air-inflation type wind energy parasail device with a center bracket, which comprises a stretched folding center bracket, an air-inflation parasails, an air inflation and air exhaust device, an parasail pull rope, a reverse pull rope retraction device, a bracket controller and a support platform, wherein the stretched folding center bracket has the function of stretching, adjusting an elevation angle and hanging the parasails; the support platform has the function of adjusting a rotation angle along the wind direction; and the center bracket is also provided with a multi-stage structure for spreading and hanging a plurality of parasails. The air-inflation type wind energy parasail device realizes the spreading and retracting of the parasails through inflating and deflating to the parasails, the reverse pull rope retraction device and the stretching and retraction of the center bracket. With the characteristics of stable parasail posotion, fixed parasail shape, large wind bearing area, high wind bearing position, high wind energy utilizing rate, simple and convenient spreading / retracting operations, very high reliability and the like, the provided wind energy parasail device not only can be used as a wind power device for the sailing of the ship, but also can be used as a wind power supplementing device for the sailing of the present fuel-firedpower ship.

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
