Description

Off-line adjustable remote-suspension wind energy parasail device with dual airbag system

technical field

The invention relates to a remote-suspended wind-energy parasail with off-line control of a double airbag system which utilizes ocean wind energy as the ship's navigation power, and belongs to the technical field of ship power and wind energy utilization.

Background technique

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.

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 early as 5,000 years ago, large-scale sailing ships appeared and began to sail across the Mediterranean Sea; in order to adapt to various types of natural winds, the sails, masts and hulls of sailing ships gradually developed towards refinement and specialization. From the 15th century to the middle of the 19th century in the "Great Discovery Age", fast sailing ships, schooners, warships and various multi-sailing ships spread all over the oceans of the world. People made full use of sailing ships and wind energy to explore the ocean and discover new continents. It has made important contributions to the development of human civilization.

Wind energy is a renewable or sustainable energy source. Among various wind energy resources, offshore wind energy has strong regularity. Of course, it also has certain randomness in wind force and direction. Therefore, wind energy can be used as the An important supplement of power can save a lot of fuel. Among modern ships, powered sailboats have also appeared, the structure of which is to install fixed masts and cloth sails on the hull, and control the direction of sail cloth deployment according to the wind direction and course. For example, the "Shin Aide Maru" cargo ship launched in 1980 has a tall mast on the deck, and the brackets on the mast support the cloth sails. Computers are used to analyze the wind and weather conditions, and calculate the sail and engine. The best use plan, when the wind force is strong and the wind direction is suitable, you can rely entirely on wind energy to pull the ship to sail. As an "extra" supplement to a gasoline engine, it can save at least 20% of fuel.

At present, the international circulation of goods is mainly completed by sea transportation. Since the fuel energy consumed by sea transportation accounts for a considerable proportion every year, how to make full use of sea wind energy to drive ships or as a power supplement for existing fuel ships , is a question that should be considered at present.

For sailing ships with fixed masts, there are generally higher masts. When the wind is strong, a larger tipping moment will be generated. The fixed masts and cloth sails will occupy a larger space on the ship deck. For wind speed, there will be obvious differences with the change of height, this phenomenon is called wind shear; in general, the wind speed due to wind shear phenomenon is a power function relationship of height; therefore, the wind speed at a higher position Large, with high utilization rate of wind energy. Therefore, sailboats with fixed masts have low wind receiving efficiency due to the low space for deploying cloth sails; if the height of the fixed mast and the area of cloth cloth are increased, a series of safety hazards will also be brought, and, when the ship enters and leaves There are also more problems in port due to the taller mast.

Offshore wind energy is a renewable primary energy source. If it can be directly used as power without energy conversion (for example, multiple conversions are required for power generation), this in itself can improve the efficiency of wind energy utilization. If wind energy at a higher position can be used , the utilization rate can be further improved. Therefore, it will be an important development direction to use offshore wind energy as a supplement to existing power ships. The key is to design and manufacture a wind energy drive device that is safe, reliable, easy to use, and low in cost. .

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 bigger problems in its stability and the implementability of the umbrella-shaped sail. The patent document "Expansion System of Kite Sail Type Windward Parts for Flying Out in Ships with Wind Power Drives" (200580020233.7) (publication number CN1968850) proposes to use a vertical fixing device for deployment, and the kite sail is recovered only through the main cable In the case of low wind or no wind, if the cable is not recovered in time, the parasail after deployment will fall into the water. Moreover, the wind has a certain degree of randomness, and the main sail cannot be used frequently. Although it is also proposed that the parachute released by a fast retraction of the traction rope is used to open quickly during the emergency retraction process, only a general parachute is used to realize the landing process. 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., All do not propose to have the scheme that can implement.

The patent document "Retractable and Retractable Remote Suspension Wind Energy Parasail Device for Ship Navigation" (201010194857.3) (publication number CN101844614A) provides a retractable and retractable remote suspension wind energy umbrella sail device, which is a single airbag system , the gas to be filled is lighter than air, and the release and recovery of the parasail must operate on the entire air bag. There is no reverse cable on the sail, which greatly affects the stability of the umbrella sail under the action of wind; because there is no horizontal and vertical adjustment device that can simultaneously adjust the umbrella surface, it is difficult to simultaneously adjust the height and direction of the umbrella surface In addition, the entire inflation device is placed on the hull, and then connected to the hull through a longer inflation tube for inflation. Because the inflation and extraction hose is longer, the efficiency of the entire inflation and extraction is low.

Detailed ways

Principle of the present invention, structure and specific implementation will be further described below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of a remote-suspension type wind energy parasail device provided by the present invention with off-line control of a double airbag system, the remote suspension type wind energy parasail device contains a main umbrella 1 and a suspension umbrella sail 2; The parasail comprises a main parasail air bag system 18, a main parasail drag cable 3, a main parasail expansion ring 7, a parasail center air hole 8, a main parasail inflation and extraction device, a main parasail inflation hose 13 and a main parasail Umbrella surface cable; the edge of the main parasail umbrella surface is connected with the main parasail extension ring 7; the suspension parasail 2 includes a suspension parasail charging and pumping device, a suspension parasail inflation hose 23, and a suspension parasail surface drag cable 24. Suspension parasail expansion ring 25 and suspension parasail airbag system, the edge of the suspension parasail expansion ring 25 is connected to the parasail main cable 3 through the suspension parasail surface cable 24; Suspension parasail inflation hose 23 is connected. The suspended parasail airbag system is composed of two types of airbags: the suspended parasail airbag 26 and the suspended gas closed airbag 6 .

Figure 2 is a schematic diagram of the main parasail surface. Main parasail airbag system 18 is made up of main parasail sail surface 21 and main parasail expansion ring 7, and the edge of main parasail umbrella surface is connected with main parasail expansion ring 7; The main parasail airbag system is remotely inflated and pumped through the main parasail inflation hose 13, and the main parasail remote inflation and pumping device is fixed on the main dragline of the parasail. The mainsail bladder system can be filled with air or a lighter-than-air gas. Horizontal cable adjustment limiter 10 and vertical cable adjustment limiter 11 are also housed on the main parasail. On the limiter 10, the vertical edge of the expansion ring is connected on the vertical cable adjustment limiter 11 through the vertical cable 5 of the parasail surface, and the horizontal cable adjustment limiter 10 and the vertical cable adjustment limiter 11 All are fixed on the parasail main dragline 3. Its function is to adjust the horizontal and vertical directions of the main parasail, so as to better control the height and direction of the parasail and make it more stable.

When releasing, in order to make the parasail device more stable and easy to control under the action of wind force, the main parasail is also provided with a main parasail back cable 19 and a main parasail back cable retractor 20, and the retractor is fixed. At the parasail stay cable 3, it is connected to the back side of the main parasail sail surface 21 by the reverse stay cable. At the same time, the back side of the main parasail umbrella surface is also provided with air-filled stabilizing wings 9.

Fig. 3 is the schematic diagram of suspension parasail sail surface, and suspension parasail sail surface 27 is made up of suspension parasail air bag system and suspension parasail expansion ring 25, and there is parasail central airflow hole 8 in the middle, and wherein suspension parasail air bag system is formed by suspension parasail air bag system and suspension parasail expansion ring 25. The parasail air bag 26 and the suspended gas closed air bag 6 are composed of two types of air bags. One is a closed air bag filled with suspended gas, which does not need to be frequently charged and discharged. It should be filled with a gas that is lighter than air, such as hydrogen or helium, to play the role of suspension, and it should always be inflated. It can be used for a long time after being filled once; the other airbag is filled with air. When the parasail needs to be released or retracted, It is necessary to inflate or pump the suspended parasail air bag 26 through the suspended parasail remote air inflation device 22 . Due to the use of multiple closed airbags filled with suspended gas, which are wrapped in airbags that can be filled or extracted, when inflated, the suspended parasail will be fully unfolded. In addition to the suspension function, it also has the ability to withstand wind Function; when the suspended parasail air bag 26 is pumped and recovered, the suspended parasail will be completely folded, but each part of the suspended gas closed air bag 6 is still filled with lighter gas, which only takes up a small space.

When releasing, first inflate the airbag 6 closed by the suspended gas, such as hydrogen or helium, so that the entire parasail system has a lift, so that the parasail floats, and keeps inflated all the time, and no longer pumps after being filled. Then release the parasail main dragline 3 step by step, so that the parasail rises, when reaching a certain height, the main parasail airbag system and the main parasail expansion ring 7 are inflated by the remote charging and pumping device 12, and at the same time, by The remote charging and pumping device 22 inflates the suspended parasail air bag 26 and the suspended parasail expansion ring 25, and the filled air makes the air bag reach a certain air pressure and has a certain rigidity, which will play a role in supporting the skeleton, so that the main The parasail and suspension parasail are opened.

After the parasail is unfolded, for the horizontal cable adjustment limiter 10 arranged on the main parasail, the left end direction or the right end direction of the main parasail can be adjusted through the horizontal cable 4 on the surface of the main parasail, so that the overall level of the parasail The direction is adjusted; for the vertical cable adjustment limiter 11 arranged on the main parasail, the upper or lower direction of the main parasail can be adjusted by the vertical cable on the surface of the main parasail, so that the overall vertical direction of the parasail can be adjusted .

When factors such as no wind, low wind force, harsh sea surface wind conditions, and entry and exit of ports cause the parasail to be retracted, the airbag system of the main parasail 1 can be pumped through the main parasail remote inflation and pumping device 12. At the same time, the airbag system of the suspended parasail will be pumped through the remote inflation and pumping device 22 of the suspended parasail, and the suspended parasail will become a folded state at this time, but the closed airbag 6 of the suspended gas will still maintain Inflated state, therefore, the whole parasail system is still in a suspension state, and the parasail system can be recovered by recovering the parasail main dragline, so that it returns to the support on the ship.
