In the present invention, applied fluid mechanics principle, according to the aerodynamic characteristic of sail (arc bent plate airfoil fan), is linked at sail (aerofoil profile) on a vertical shaft dexterously, allows sail around vertical shaft travel (rotation).Use exactly simple mechanical component, replace athletic manipulation, and require perfect more flexibly than manual control.From the principle, the qualitative leap of the ancient vertical shaft Big Pinwheel of Zhe Shi China, it has converged the advantage of various vertical axis windmills nowadays and has made.
In Fig. 7, blade shroud is around vertical shaft (Z) rotation, and in Fig. 8, the theoretical efficiency of propeller-type horizontal-shaft wind turbine is 59.3%, and practical efficiency is generally in 30% left and right.With reference to the computational methods of propeller-type device, of the present invention this device, its practical efficiency with wing chord the projection on its rotating diameter relevant.Through wind tunnel test, the practical efficiency of three impeller assemblys can reach more than 30%, and quaterfoil device has reached more than 40%, not poor upper and lower with nowadays advanced propeller-type horizontal-shaft wind turbine.
To utilize the airfoil theory of lift as major impetus source, be the theoretical foundation of modern sail, be also the theoretical foundation of this sweep type wind power device of research.Propeller-type horizontal-shaft wind turbine and existing other vertical axis windmill, be taking its " effect disk " and cylindrical " pressure planes " as area of passage, calculates its wind energy conversion efficiency.For this wind sail type device of research, should calculate its efficiency with the area of sail.Because " arm " of (catching sail) in this device lengthens than being easier to.Use common material (steel, artificial fiber, timber etc.) to catch sail, just can draw wind energy in larger space.Be below sail type blade of Fig. 9 (circular arc bent plate aerofoil profile) on larger rotating diameter, while circling around central shaft public affairs (360 ゜), suffered maximum thrust coefficient curve.Zhe Jiu Said is bright, and wind sail type vertical axis windmill, even a blade also can effectively utilize wind energy.
The structural type of this device, has formed a kind of new spiral.Because the performance of this spiral in fluid, can provide technical equipment for Devoting Major Efforts To Developing renewable energy sources, research people gives this new spiral form, has played name---the propeller cavitation II of a fashion.The meaning of propeller cavitation II is as follows:
One, when the vertical axis windmill, device can automatically meet to, oneself starts, adjusting vane angle automatically, and automatically avoid high wind; In scope of design, can also automatic speed regulation, automatically adapt to load.Compare with existing all kinds of vertical axis windmills, its advantage is that startup wind speed is low, and without the maximum wind speed of shutting down, available wind speed is wide, and efficiency and automaticity are high, safe and reliable.Recently for over ten years, Chinese large-sized wind power technology is all from external introduction, and cost is higher, and production capacity surplus.We can create world-class inexpensive wind-driven generator, create our own best national brand, and society promotes the well-being of mankind.
Two, can be used for making free flow, submerged type, horizontal shaft water-turbine (by test).This water turbine is installed, need not be built a dam, also need not do factory building, cross ship, cross the hydraulic structures such as fish, sand prevention; Be not subject to the restriction of the depth of water and flow velocity, do not affect ecology yet, have mobile water just can generate electricity; Single-machine capacity can be from several hectowatts to thousands of watts and even hundreds of kilowatts, and its efficiency is far above traditional free flow water turbine; Simple in structure, and without the anxiety of runaway speed; The emphasis of engineering is device fabrication, thereby construction period is short, cost is low, instant effect.This for exploitation China's abundant low water head water energy, particularly develop tidal energy, the energy by ocean current on 18000 kilometers of shore lines of China, by significant.There is at the same time water can have again the place of wind energy, should first develop water energy, because the proportion of water is more than 800 times of air.
Three, the mode of structure of propeller cavitation II and manufacturing process are fairly simple, draw materials also relatively easy.This just for low cost, develop wind energy and water in large area and can create condition.All have wind energy and water can place, can build charging station, a grid-connected group of planes, or pump station, agricultural byproducts processing station, hydrogen production by water decomposition station, air compression station, desalination of sea water station etc.Once promote, popularize and can, than very fast, also meet the national conditions of China.
Four, there is vast desert area in China, and it is almost impossible removing large size desert with conventional energy resource.And had wind energy plant simple in structure, with low cost, utilize wind energy to go large size desert will become possibility.
Five, Chinese Big Pinwheel has disappeared over half a century.Along with our further investigation to sail technology (circular arc book plate aerofoil profile), in setting up the theoretical system of a new spiral, new technology can allow Chinese Big Pinwheel again rotate in the large ground of China with new looks.
The corresponding same or analogous parts of same or analogous label; In accompanying drawing, describe position relationship only for exemplary illustration, can not be interpreted as the restriction to this patent.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can do the improvement of some applicable actual conditions to the technological scheme of invention.Therefore, protection scope of the present invention is not limited to this, and those of skill in the art are any to be included within protection domain of the present invention based on non-material change in technical solution of the present invention.
