Retractable inflation-type wind energy umbrella sail device with double brackets

Abstract

The invention discloses a retractable inflation-type wind energy umbrella sail device with double brackets, which comprises an extension-type retractable stressed bracket, an inflated umbrella sail, an inflation and pumping device, an umbrella sail pull rope, a reversal pull rope releasing and withdrawing device, a bracket controller and a support platform. The extension-type retractable stressed bracket has the functions of extension, adjustment on an elevation angle, suspension of the umbrella sail and bearing pulling force, the support platform has the function of adjusting a rotating angle along the wind direction, and the stressed bracket also has the function of suspending multi-level structures of a plurality of umbrella sails. The retractable inflation-type wind energy umbrella sail device realizes the releasing and the withdrawing of the umbrella sail by inflating and pumping the umbrella sail as well as the extension of the reversal pull rope releasing and withdrawing device and the stressed bracket. The disclosed device has the characteristics of stable position of the umbrella sail, unchanged shape of the umbrella sail, large wind area, high wind position, high utilization rate of wind energy, simple and convenient releasing and withdrawing operations and the like, is quite high in reliability, and can be used not only as a wind power device for ship sailing, but also as a wind power supplementing device for the sailing of traditional oil burning vessels.

Description

technical field [0001] The invention relates to a retractable inflatable wind energy parasail device with double brackets which utilizes ocean wind energy as ship navigation 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. As ...

Problems solved by technology

[0009] In the patent document "A Retractable Inflatable Wind Energy Umbrella Sail Device for Ship Navigation" (201010131058.1, Publication No. 101786498A), the umbrella sail retracting device provided is a separate bracket, which can only play the role of hanging the umbrella sail. And it is in a separated state from the parasail, and it 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. There is no tight cable connection between them, especially if there is no reverse cable, when there is side wind or even reverse wind, the parasail will be affected by the wind, and its position will become very unstable; when it is recovered, Only rely on the pumping of the parasail, and then hang it on the bracket of the retracting device. Similarly, it is also seriously affected by the wind, that is, the bracket of the retracting device has little effect on the stability of the parasail. There are obvious deficiencies in the operability and stability of parasail release and retraction
