Retractable inflatable wind energy parasail device for ship navigation

Abstract

A retractable and retractable inflatable wind energy parasail device for ship navigation, comprising an inflatable parasail, a parasail retracting device and a parasail cable. The umbrella sail retracting device has the functions of telescopic, elevation angle adjustment, rotation angle adjustment with the wind direction, and umbrella sail hanging when there is no wind. The shape of the umbrella sail that can be inflated has various forms. The inflatable wind energy parasail device of the present invention realizes the release and retraction of the parasail by inflating and pumping air. For the situation of side wind, the parasail can be released sideways, and the comprehensive adjustment method of rudder can be used to adjust the wind direction and heading. The proposed wind energy parasail device has the characteristics of stable position of the parasail, fixed shape of the parasail, large wind receiving area, high wind receiving position, high utilization rate of wind energy, and easy operation of releasing and retracting. It can be used as a wind power device for ship navigation, It can also be used as a wind power supplementary power device when the existing fuel-powered ship sails.

Description

technical field [0001] The invention relates to an umbrella sail structure and device 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. As early as 5,000 years ago, large-scale sailing ...

Problems solved by technology

[0008] In recent years, there have been some inventions using wind energy, such as "umbrella-shaped sailboat" (200810036632.8) (publication number CN101565100), which includes complex devices such as sails, titanium alloy rings, and liquid hydrogen tanks, but has no release and retraction devices. There are big problems in its stability and the implementability of umbrella-shaped sails

In another patent document "Expanding System for Flying Kite-type Windward Parts in Ships with Wind-Driven Devices" (200580020233.7) (publication number CN1968850), a vertical fixing device is used to release, and the platforms cannot be released simultaneously. Adjustment of elevation angle and self-rotation, this device does not have the function of kite sail recovery, the kite sail recovery is only completed by the recovery of the main cable, in the case of small or no wind, if the cable recovery is not timely, The parasail will fall into the water after being released. Moreover, the wind force has certain randomness, and the recovery of the main cable cannot be frequently used for operation.
