Retractable long-distance suspension wind-energy parasail device for ship navigation

Abstract

The invention relates to a retractable long-distance suspension wind-energy parasail device for ship navigation, which comprises a suspension parasail, a parasail retracting and releasing device, an inflatable and evacuating device and a parasail inhaul cable, wherein the suspension parasail is connected with the parasail retracting and releasing device through the parasail inhaul cable; a parasail surface inflatable air bag and a parasail top inflatable air bag are arranged in a parasail surface, and an inflatable direction wing and an inflatable stabilizer are also arranged in the parasail surface; gas lighter than the air, such as helium, hydrogen and the like, can be inflated into the air bags; and the parasail surface is also provided with a plurality of parasail in-series structures. The suspension wind-energy parasail device realizes the release and retraction of the parasail through inflation and air suction. The long-distance suspension wind-energy parasail device provided by the invention has the characteristics of stable parasail suspension position, fixed parasail shape, large wind areas, high wind position, high utilization rate of wind energy, simple and convenient operation of release and retraction and the like, can be used as both a wind-force device of ship navigation and a wind-force replenishing power device for the navigation of the conventional fuel oil power ships.

Description

technical field [0001] The invention relates to a retractable long-distance suspended parasail structure and device which utilize 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 in less than 100 years Exhausted. 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 earl...

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

The patent document "Expansion System of Kite Sail Type Windward Parts for Flying Out in Ships with Wind Drives" (200580020233.7) (publication number CN1968850) proposes to use a vertical fixing device for release, and the release platform cannot simultaneously adjust the elevation angle and self-defense. Rotation adjustment, this device does not have the function of kite sail recovery, the kite sail recovery is only completed through the recovery of the main cable, in the case of small or no wind, if the cable recovery is not in time, the The parasail will fall into the water, besides, the wind has a certain randomness, and the recovery of the main cable cannot be frequently used for operation

The patent document "A Marine Device Using Floating Sails to Generate Propulsion" (200810034057.8) (publication number CN101519114) also proposes the idea of ​​floating sails one by one. For release and recovery methods, floating structures in the air, floating stability, etc., No implementable plan was proposed
