## Background
CROSS REFERENCE TO RELATED PATENT APPLICATION
This application claims the priority of the Chinese patent application No. 201110259162.3 with filing date of Sep. 5, 2011, which application is incorporated herein by reference.
FIELD OF THE INVENTION
The invention relates to two industries of architectural complex construction and wind power generation, in particular relates to high and super-high architectural complex construction.
BACKGROUND OF THE INVENTION
Energy status—The world energy crisis and environmental pollution have reached an extent of extremely urgent; Academician Tan Jiazhen, a famous genetics expert in our country described in a book named Gene Wealth: “The world crude oil shortage leads to continuous rising of the crude oil price; within 400 years, human almost used up petrochemical type energy accumulated by the earth for 2.5 billion years—petroleum, coal and natural gas. According to statistics, the fixed numbers of years for mining of the three energies are respectively 40 years, 50 years and 240 years, and human must find new energy sources.” On 20 Dec. 2007, Reference News reprinted a report of Lianhe Zaobao of Singapore: Professor Yang Zhengning said: “I am a very lucky man . . . now it seems that the relation between China and United States will not be a problem within twenty to thirty years, . . . but it cannot be expected after forty or fifty years, the main reason is that human are facing many complex problems, especially resource problems, energy problems and pollution problems; by then conflicts are intend to exist between the two countries because China and United States influence the world too much.”
Current status of the wind power generation device: For the prior wind power generation devices, the impellers are pushed by the natural wind speed directly, the best wind speed probability thereof is about 6 ̃8 m/sec; New Energy Generation Technology wrote and published by Wang Changgui and so on in our country in 2003 described that: “Nowadays the power of main wind turbine generator system has risen to 600 ̃700 KW, the generator system of MW grade also has been manufactured; at present 2 MW grade generator system has been manufacturing, and most of them are three-blades horizontal axis.” The accumulated installed capacity of wind turbine generator system of our country in 2008 had reached 12,000,000 KW, and the annual growth rate was 120% in 2007. In chapter 1.2 “Modern wind turbine” of Wind Energy Technology by Tony Burton from United States, it is described that a 1.5 MW wind turbine needs an impeller (refers to three-blades horizontal axis wind turbine) with diameter greater than 60 m. At present, some countries use high towers (60 ̃80 m) in the wind field by using the principle that the wind speed increases with the height increase, according to above-mentioned book by Wang Changgui, it is described that:” The wind speed is 2 m/sec at 20 m position from the ground, however the wind speed is changed to 7 ̃8 m/sec at 300 m position from the ground after measurement; according to the formula of the change between the height and wind speed, it is calculated that the wind speed at 80 m height position is doubled than the wind speed at 20 m height position.
The domestic design parameters for above-mentioned three-bladed type 1.5 MW generator and speed increaser at present are generally: the rotation speed of the low speed shaft (blade) is 30 r.p.m, the rotation speed of the high speed shaft is 1800 r.p.m, the speed increasing ratio is about 60, so the torque of the low speed shaft is about 48750 kg-m, generally such a moment is realized by 2 stage NGW speed-increasing type planetary transmission, the single stage speed-increasing ratio thereof is about 8; taking the maximum diameter of the general annular gear machine tool in the past as 2 m (now it has been developed to 3 ̃4 m), when the number of teeth is 142, the modulus is about 14 mm, the tooth width B=300 mm, then the peripheral force Ft of a single tooth surface is about 16250 Kg, the basic bending stress of the tooth profile is 4 kg/mm2, this stress is approximate to the license threshold of ordinary materials; however above-mentioned tooth profile parameters only can be met by y51200 gear slotter by few heavy machinery plant; known from aforesaid, for the processing capability of the planetary speed increaser of the present horizontal shaft three-blades wind turbine, gear slotter with inner diameter of 2 m can hardly adapt when the power is above 2000 KW, but the single machine capacity of the fire power generation unit is as high as 600,000 KW, the single machine capacity of the gas turbine for peak shaving of the power system is as high as 120,000 KW, however the energy for the latter two is about to be exhausted. It is clear to be see that people must surpass many conventional concepts, make some discoveries and progresses so as to replace the fire power and gas turbine generation devices with conventional wind power generation devices. Su Dongpo wrote in Former Fu on Red Cliff: “ . . . only the wind on the river and moon on the mountains are inexhaustible, and are given by the Creator and can be used by all the people . . . ”. Our invention is also originated from what Su Dongpo said.
The building construction industry of our country has a great development in relation to wind speed, wind pressure standard, earthquake and seismic fortification, and it is all the more so in Nanjing where we live; tall buildings with various postures and beautiful architectural modelings can be seen everywhere, however the shortage is that all the buildings have no wind concentrating effect described by our inventor and cultural connotation of generation with them; all are the same both home and abroad, but they has been developed by several common features as follows: the first one is as super-high buildings, their outer walls almost are closed glass walls and concentrated central air conditioners are adopted the second one is that they all are built on six floors of podiums. The building design in our country, especially high and super-high building design is very sophisticated, and the standards for wind load also are explicitly stipulated, for example, in Building Structure Load Norms, the national wind pressure distribution map has explicitly stipulated the basic wind pressure Wo value of each region, wherein: Tainan and Taipei is 1.2 KN/m2; Shantou, Jilin and Xiamen is 0.75 KN/m2; Kiamusze, Shenzhen, Zhanjiang and Haikou is 0.7 KN/m2, Shanghai is 0.55 KN/m2; Nanjing is 0.35 KN/m2 and so on; the basic wind speed Vo≈24 ̃44 m/sec, and it's known that the designed basic wind speed of railway bridge in the northwest region of our country Vo≈70 m/sec.
About the seismic fortification problem of the buildings, in our country it is stipulated that high buildings are provided with seismic fortification within 6 ̃9 magnitudes; our country is an earthquake country, especially earthquake occurs frequently in the earthquake zone regions from Yunnan, Sichuan, Shaanxi, Shanxi to Tangshan of Hebei province; classic buildings of our country have excellent earthquake-proof structures, such as the wall and rostrum of Tian An Men, Jinian Pavillion of Temple of Heaven, which are not destroyed after hundreds of years; in recent 10 year, many high buildings mansions are built in the national large and medium-sized cities, however their common features are mostly rectangular section and the length of their short sides are always 30 m or even smaller, hence their inertia radiuses of bending resistance and torsion resistance are relatively small and are not beneficial for earthquake resistance. For example: Taking a solid body with base area of 24×90=2200 for example, disassembling it into three-star shaped buildings with included angle of 120°, the size of each small rectangle is 12×62, and each short side is circumscribed with a circle with diameter of 12 m to constitute an integral structure architecturally, then the bending resistance section modulus of the side surface of the former is about 8640 m3, the latter is as high as 68000 m3 and is increased by 7.8 times, therefore the shock strength against the horizontal shock wave is greatly enhanced.
The southwards moving phenomenon of sandification in our country is serious and worrying, the inventor has worked in Beijing for years at the beginning of 1950s, at that time sand trace on car can be seen only several times every year as today's Nanjing (at that time the sand trace was on the clothes); in April of the year before last, we saw the sand storm in Beijing which is said not to be heavy, but we never seen in that time.
Waterlogging phenomenon as well as drought appear in cities and countrysides every year in our country, however the vastly Yangtze river still runs into the sea at the rate of about 10,000 m3/sec, then 300 billion tons of water runs into the sea every year; if the head thereof is lifted by 50 m to send to Beijing, 5 million KW is needed, which is equal to 30 ̃50 open-field power stations of our invention; because of shortage of energy, water operation channels and operation mechanisms, the water cannot be transferred freely; If the water in the river in one year is transferred by wind power into the Gobi Desert, the southwards moving phenomenon of sandification will not be a problem; and so far south-to-north water diversion project only rests on natural slope flowing way. Therefore this problem can be solved by the power station of our invention by installing with a super high power water pump; if human cannot conquer the nature, how about conquer the nature by nature?

Principle of Invention:
As known to all, the power W perpendicularly flowing through the blade section F in a unit time is proportional to the third power of the wind speed V, namely ρFV3 (In the formula, ρ is the air density); the prior conventional wind power generators all adopts natural wind speed, however our invention uses the principle of above formula so that the natural wind forms an integral speed-increasing space after passing through the outer wall of the architectural complex, or outer panel 31 of the structural truss, ceiling cover 13 and speed-increasing windage floor 29; the speed of the natural wind is increased continuously when flowing to the entrance ventilation door 6 of the through the entrance surface of the speed-increasing windage and chord length thereof 36, for example if the chord length 36 of the entrance surface of the speed-increasing windage is 100 m, the chord length of the entrance ventilation door 6 is 10 m, then the speed-increasing ratio of the wind speed is 100:10, namely the wind speed is increased by 10 times (Local resistance is ignored); if the natural wind speed is 5 m/sec, then the wind speed acting on the blade of the impeller of the central tower is 50 m/sec, the power thereof is increased by 103=1000 times compared with the natural wind with the same blade area. Our invention can adjust the wind speed entering the tower by using the circumferential adjustability of the windage exit area and adjustability of the circumferential and radial covering surface of the ceiling cover 13 (part or all of which are unloaded when the natural wind is quite strong) so as to keep the generator to rotate at a constant speed.
Advantages of Invention
1. The scope of conventional wind energy resources is enlarged; as the speed increasing effect of our invention, the conventionally adopted wind energy resource 6 ̃8 msec is reduced to about 3 m/sec, so vast regions have available wind energy resources.
2. The natural wind generator with non-adjustable rotation speed is converted to an adjustable constant-speed wind turbine generator.
3. As the constant speed wind turbine generator is created which creates advantageous conditions for grid connection, the difficulty of grid connection of the conventional wind turbine generator is overcome.
4. The distance between users is shortened and the costs of power transmission equipments are greatly reduced.
5. Our invention can directly provide power supply, heat source, cold source and power source to the residences, offices, industrial housings, commercial housings and surrounding buildings of the buildings in our invention.
6. As the rotation speed of the turbine is increased from 30 r.p.m of the conventional wind turbine to 200 ̃300 r.p.m, so the drive torque is reduced by 5 ̃10 times, the cost of the transmission gear is reduced by 5 ̃10 times, and the processing difficulty of the transmission gear of the large wind power generator is greatly reduced.
7. As the concentrated transmission is adopted, the land area and administrative expenses are greatly saved.
8. The power of a single generator unit is promoted from 2000 KW to 20,000 KW, even 5 ̃10 KW/set.
9. It is possible to replace petroleum, coal and natural gas with our invention after the petroleum, coal and natural gas are exhausted.
Take the power supply in Beijing in 2007 for example: provided that the power supply capacity per capita is 0.84 KW (It was reported by radio broadcast on 30 Nov. 2007 that the total power supply capacity is 8.37 million KW, provided there are 10 million people, then the power supply capacity per capita is 0.84 KW), and the building per capita is 20 m2, then 60000 m2 power station buildings can provide the power supply capacity of 3000 people, however the capacity for itself only needs 3000×0.84=2520 KW, the rest part can be used for external supply; provided that a 20000 KW generator normally operates 6000 hours every year, then electric energy production is 120 million degrees, provided that the price is 0.5 yuan/degree, then the yearly gross profit is about 60 million yuan. For an open-field wind power station, the natural wind speed is 8 m/sec, the speed increasing ratio is 9, then the outlet velocity thereof is about 70 msec, when the diameter of the rotor thereof is 16 m, the height of a single floor is 4 m, then the power of a single floor can be as high as about 5000 KW; provided there are 30 floors (the total effective height is 120 m), then the total installed capacity can be as high as 150,000 KW; therefore for architectural complex, the outlet wind speed of our invention is preferably 50 m/sec; for the open-field wind power station, the outlet wind speed is preferably 70 m/sec; this is the same as the speed increase of the train, the speed thereof can be increased with the improvement of technology.
The invention can increase the wind speed of the architectural complex type wind power station from light breeze at 3 m/sec to 50 m/sec (the speed increasing ratios is 16, inland type) without breaking the building design specifications, while the wind speed of the open-field wind-concentrating power station can be increased from natural wind resource (8 m/sec) to 70 msec; as the generation power of the wind turbine is proportional to the third power of the wind speed (same as above-mentioned book P 178), compared with prior three-bladed horizontal axis impeller natural wind speed generating station (the ideal natural wind speed is fresh breeze 8 ̃10 m/sec, which takes 20% of the yearly probability), taking the sane 10 m/sec natural wind for example, the generation powers of the unit blade frontal area of our invention are increased by 125 times and 343 times; when the heights of the towers are approximately the same (about 100 m), our invention can obtain an frontal area of  ̃800 m2 when the diameter of the blade is 18 m, however for the 2000 KW device in the prior art, when the diameter of the blade is 60 m, only about 100 m2 frontal area can be obtained; therefore the architectural complex wind power station of our invention is preferably 10,000 ̃50,000 KW, while the open-field type hub units can be as high as 50,000 ̃150,000 KW.
The ceiling cover 13 of the architectural complex wind power generating station and the ceiling cover 13 of the open-field wind power generating station also can adopt partially radial or circumferential open-type structures to reach the purpose of unloading with a single drive system by opening and closing the wire cable, and also the speed of the wind turbine can be closed or adjusted by closing or adjusting the entrance ventilation door 6 in the trapezoid cubical space.
