Description

Sail wind power generator

One, affiliated technology contents: the utility model relates to a kind of wind generating unit.

Two, technical background: the principle of wind-power electricity generation is to utilize wind-force to drive the air vane rotation, sees through the speed lifting of booster engine with rotation again, impels generator for electricity generation.According to present windmill technology, approximately be the gentle breeze speed (degree of gentle breeze) of three meters of per seconds, just can begin generating.Wind-power generating system efficient is very high, but it is not only to be made up of a generating head, but one is made of the mini system that certain scientific and technological content is arranged wind-driven generator+charger+digital inverter.Wind-driven generator is a permanent magnet by rotor, thus the staor winding cutting magnetic line produce electric energy head, can make head rotate neatly with realize empennage adjust the function of direction turn, make blade all the time facing to the direction of the wind comes from obtain maximum wind energy empennage, be used for accepting wind-force and form by the blade that head transfers electric energy to.Each part is all very important.Wind-driven generator so its output is the Ac that 13～25V changes, must again to the storage battery charging, make the electric energy of wind-driven generator generation become chemical energy because of the air quantity instability through the charger rectification.With the inverter that protective circuit is arranged, the chemical energy in the storage battery is transformed into the alternating current 220V civil power then, could guarantees stable the use.

Existing at present all over China more than 40 wind power plant of present situation builds up generating, and maximum wind power plant is positioned at Inner Mongolia Autonomous Region.This wind power plant plan to 2008 year becomes the wind power plant of Asia maximum.Simultaneously, China is by law, and decision encourages to promote the use of the non-mineral energy such as waterpower, wind-force and solar energy with tariff and otherwise preferential measure.In the medium-term and long-term development plan of putting into effect in 2004 of national energy, the wind energy power supply as main energy project, has been proposed 4,000,000 kilowatts of wind-powered electricity generation electric motor powers in 2010, the year two thousand twenty reaches 2,000 ten thousand kilowatts target, and wind-powered electricity generation will account for 2% of total installation of generating capacity when the time comes.

The advantage wind-power electricity generation is environment friendly and pollution-free, does not expend the energy, is not subjected to the region, time restriction, wide accommodation.

Though the problem wind-power electricity generation has various advantages, have two root problems not avoid: cost and wind-force, in present these material gain epoch, interests are most important, also are that people are concerned about most.For the previous period, green wind-powered electricity generation is sold in Shanghai for charity, has major company such as Baosteel to go to buy, and the presell price of " green " reaches 0.8 yuan/kilowatt hour, amounts to the group of motors cost that becomes a common practice, then above 10,000 yuan/kilowatt; Even Phaeton tin is reined in wind field in the Inner Mongol, the comprehensive cost of wind-powered electricity generation factory has also reached 0.78 yuan/kilowatt, is 0.45～0.5 yuan/kilowatt hour and wind-powered electricity generation contains the tax rate for incorporation into the power network, exceeds common electricity price more than 50%.Why how high is the cost of wind-power electricity generation? because the price of wind-powered electricity generation unit import equipment exceeds 30% than domestic equipment, and equipment cost has accounted for 80% of cost of electricity-generating, because equipment is dependence on import too, directly cause China's wind power cost to rise, than conventional electric power energy such as thermoelectricity, water power, its cost is lacked competitiveness.According to the measuring and calculating of relevant department, under existence conditions, the average cost of wind-power electricity generation is minimum will be at 0.60 yuan/degree, if employing import equipment, then need higher electricity price, and the average cost of thermoelectricity only is 0.30 a yuan/degree at present, the competition inferior position of wind-powered electricity generation is apparent.The first half of the year in 2006, China's wind-powered electricity generation project bid quantity obviously reduces (only having two projects to carry out international bidding), is good evidence.

The wind-force aspect will solve wind speed and wind-force problem.In general, gentle breeze just has the value of utilization.But from the angle of economical rationality, wind speed just is suitable for generating greater than 4 meters of per seconds.According to surveying and determination, one 55 kilowatts wind power generating set, when the wind speed per second was 9.5 meters, the output power of unit was 55 kilowatts; When 8 meters of wind speed per seconds, power is 38 kilowatts; When the wind speed per second is 6 meters, have only 16 kilowatts; And wind speed only is 9.5 kilowatts when being 5 meters of per seconds.As seen wind-force is bigger, and economic benefit is also bigger.But wind speed greater than the fresh breeze of 8.0～10.79 meters of per seconds the landlocked the greater part of China the time seldom, less than 30 days, the time is very short, and only be individual hour of 3-4 mostly.One day 15 hours nearly more than 300 days be 3, moderate breeze is suddenly big or suddenly small, about change, extremely unstable, value is low.The wind-force blowing area generally based on the development blade diameter, only just considers to increase blade when diameter is restricted.So if accomplished to the year two thousand twenty China wind-powered electricity generation productive target, this is 1% of year power consumption of China's expection when the time comes only so.Although the significance of waterpower and nuclear energy will increase day by day, most of electrical production will continue to rely on coal.The cost height, wind speed is low, and the wind energy instability is the subject matter of present wind-power electricity generation.

In this correspondence, the photovoltaic of rising in this world also has the not enough problem of sunlight, and working alone is under suspicion, because the kenel characteristics of wind-driven generator are being warded off wild wilderness mostly at present, the two is difficult to a large amount of combinations, the scene electricity is in conjunction with rising greatly, and novel wind generator is demanded urgently producing.

Three, summary of the invention: be the workout cost height, wind speed is low, the wind energy instability, the scene electricity is in conjunction with problem, through research for many years, I have invented sail wind power generator, can large size, provide convenience for a long time, cheapness, environmental protection, stable, suitable wind-force electric power.

Face of land atmosphere produces the generation that variable density difference causes wind owing to heated by the different sun, have only and schedule to last few continuous high temperature and could produce strong wind, long-term having only of continuing do not utilized the little wind that generates electricity and be worth below the Pyatyi, wind-power electricity generation can not continue to carry out mostly, have only the face of land of utilization, landforms, landform, keeping watch, putting together breezes up just can turn waste into wealth, such as; The matrix passage at top, the mountain ridge can form king-sized wind, and the matrix passage also has bigger wind between building, also has the river course, highway, and wind is all very big between object; Therefore, can keep watch puts together, breeze up, and the air port generating, wind-force increases, and turns waste into wealth.If the full sail of matrix is placed the nature air port, place, building air port, continuing to keep watch puts together, and wind-force continues to strengthen, and must be successful wind-power electricity generation.

The concrete scheme that I deal with problems is the wind power generating set that is positioned at the full sail of matrix top, utilize breezing up of the matrix face of land, the gathering of landforms passage, the wind-force that the matrix sail is assembled and through around the diminishing round matrix sail air-flow path rectification that constitutes of sail cloth and generator set inside top rectifier, the air that the quickened wind-force that forms bigger air pressure assemble air pressure group, produces the wind wheel rotation that powerful, even, quick wind-force promotion is positioned at the wind power generating set at matrix sail top and generates electricity.

Wind-driven generator hangs on sail middle part on the fixture, and the rectifier of sail cloth and generator inside top constitutes diminishing round matrix air-flow path all around, and wind turbines rotor is positioned at the top of matrix sail.

The matrix sail by top fixture, bottom weight-loading rod, between the cloth that keeps out the wind form, wind-driven generator is positioned at the sail middle part, is positioned at the wind-engaging effect and is formed on the wind-force direction and has certain depth, can assemble the full sail of the streamlined concave volume top of wind-force; Change in positive and negative 90 degree of generator set position box haul winding line and move; The matrix direction changes wind-engaging to constraint.

Circle matrix air-flow path be by around the rectifier of sail cloth and generator inside top constitute.

The generator set that hangs on sail middle part on the fixture is a wind wheel by the centre, interior outer side covers rectifier, the combination of forming for generator therebetween; Rectifier cover generator all with the big portion of wind wheel, it between rectifier and canvas diminishing round matrix exhaust outlet for the connecting rod parcel, connecting rod is an arciform connecting body between rectifier and canvas, install relatively, round matrix exhaust outlet of parcel is a wind wheel blade operation passage in it, tractive generator set, wind wheel, fan blade, rectifier, its gap is by quickening air, rectifier is circular convex fairing, and wind-engaging is tried hard to recommend moving fixing, and air is through oppressing along its surface flow to exhaust outlet.

The sail wind power generator of forming by wind, fan blade, generator, rotational structure and support thereof, hang on top fixture on the fixture, bottom weight-loading rod, between the middle part of the sail formed of the cloth that keeps out the wind, generator set is fixed on the wind-engaging effect and is formed on the wind-force direction and has certain depth, the top that can assemble the full sail of streamlined concave volume of wind-force, by interior outer side covers rectifier, the centre is a wind wheel, the combination of forming for generator between the rectifier wind wheel.Rectifier cover generator all with the big portion of wind wheel, the diminishing round matrix exhaust outlet that is connected for connecting rod between rectifier and sail canvas, it is to be made of the rectifier of sail cloth and generator inside top all around.Sail by top fixture, bottom weight-loading rod, between the wind-engaging effect on the fixture of hanging on formed of the cloth that keeps out the wind be formed on the wind-force direction and have certain depth, can assemble the streamline matrix body of wind-force; Rectifier is circular convex fairing, and wind-engaging is tried hard to recommend moving fixing, the position of while stationary power generation unit, and air is oppressed along its surface flow to exhaust outlet through it; Connecting rod is an arciform connecting body between rectifier and canvas, installs relatively, and interior is the wind wheel blade rotating channel, tractive generator set, wind wheel, fan blade, rectifier, and its gap is by quickening air.

The air draught speed of quickening through the face of land, the rectification of landforms matrix passage below subsonic speed, is incompressible gas far away, and pressurized quickens, and can produce powerful, even wind-force, and certain time-delay is arranged; The cloth rectifier gap of keeping out the wind through diminishing gradually forms once more the incompressible air pressure group of pick up speed, blows wind wheel when mobile and continues faster rotation, wind power generating set work.

Streamlined recessed direction is identical with the wind-force direction, changes before and after the box haul of generator set position, uses double-edged wind-power electricity generation.Wind increases promotes rectifier and generator set thereof and inwardly upward moves to the startup value, and the sail matrix is deepened, and rectifier is subjected to the pulling force acting in conjunction of wind-force, gravity and sail cloth and fixes, and the generator set on it is fixed, normal stable operation.Wind increases, rectifier no longer obviously moves inward, and generating increases, and matrix is no longer obviously deepened; Wind-force reduces, and the gravitate generator set moves, and is unfixing, normally stable operation, and wind-power electricity generation reduces; Wind-force disappears, wind power generating set returns vertical position, quit work, the sail matrix disappears, the low parabola shaped variation in high back before sail matrix size, the effect of depth wind-engaging power are, the pulling force acting in conjunction rectifier that is subjected to wind-force, gravity and sail cloth is fixed, and generator set is fixing thereupon, and wind motor could normal stable operation.

Because generator set only is the wind-force constraint at normal, the wind-force change retrains change, and wind direction east is come, and matrix is in the west, and wind direction is western next, and matrix can move in east, and it is mobile to change the interior variation of positive and negative 90 degree of generator set position box haul winding line less than 90 wind-force of spending; Wind-force greater than 90 degree changes, and generator set, sail are crossed center line, and the matrix direction changes, and uses the reverse side wind-power electricity generation.So as long as fan blade has suitable angle of attack degree, the wind-force of 180 degree changes, needn't rotate by 180 degree, double-edged wind-force all can use.

Working method; Sail wind power generator can be at rivers, the chain of mountains, and desert, a plurality of generator set parallel runnings in Gobi desert, double-side driving is formed a generator net utilization; Also can single generator set in family, building, building, vehicle uses on the ship, is convenient for people to the city, the rural area is used, and helps and the combining of photovoltaic industry.When wind-driven generator does not all generate electricity in any case, power supply is affected, all have sunset constantly in any case, photovoltaic is not sent out electric the time, works alone separately, even use storage battery, also make us dissatisfied, the two replenishes mutually in conjunction with mutually beneficial, just can improve usefulness, rising greatly.The scene electricity is in conjunction with the certainty that is development.

Working principle; As wind-force blow sail is blown gradually full, and with about, go up lower pulling force, the sail generator set fixed with the vertical tension that keeps up; Air is when the exhaust outlet of wind power generating set blows out, and its airspeed is owing to be to continue to carry out below subsonic speed, and air can not be compressed, and exhaust outlet is less, and the gap is reduced air gradually and is compressed, and airspeed is accelerated.According to formula f=velocity squared * blowing area * density * speed/2, calculate 3 meters wind speed of 20*20 area, generator fan blade area 7*7*3.14.Rectifier area 5*5*3.14. sail inlet power is 3*3*3*20*20*1.3/2=2340kg, sail exhaust outlet power=[7*7-5*5] 3.14* speed ³* 1.3/2, sail exhaust outlet power=sail inlet power, exhaust outlet speed is 5.3 meter per seconds, has improved wind speed, so, saying on the fluid mechanics that when exhaust outlet diminishes, flow velocity will increase, we claim the speedup coefficient.Top speedup coefficient is 1.7, and such 5 meters speed is 8.5 meter per seconds, and 10 meters is 17 meter per seconds.Certainly, because the air toughness has surface friction drag, speed does not reach calculated value; But air temperature is low, and viscous force is little, surface friction drag seldom, gas pressure increases, flow velocity increases to be determined, blow circular shape fixedly the wind-force of wind wheel drive wind power generating set work require to have reduced.Wind energy increases, and the wind wheel driving force strengthens, and sends more electric power, and efficient is higher.Like this, the wind-force when reaching 3 meters seconds that start the wind-force requirement is 5 meters seconds, is rated wind speed, can proper functioning.Like this, one day 15 hours more than 300 days is 3 nearly, and moderate breeze just can proper functioning generate electricity for a long time in a large number.

Because the air that the sail area holds more greatly is more, if the sail area has 400 meters degree of depth to have 5 meters, 2000 cubic metres air is just arranged; The time-delay of wanting 10 seconds when flowing out with 40 squares exhaust outlet with 5 meter per second flow velocitys has 10 seconds time-delay power; Although flow velocity is higher, there is air stream to lose, also can keep the regular hour; When external wind-force changed, wind-force pressure kept the regular hour, had certain delay time can regulator generator moment, adapted to wind-force and changed, guarantee generator set steadily, safety, long-term, operation continuously; Steadily, safely, continuously, for a long time, more high efficiency and driving force are significant to wind-power electricity generation.Therefore, we explain with speedup coefficient and two indexs of delay time.

The stability of generator set operation, when wind-force hour, less than 3m/ second, generator set is not worked, the stability that is far from being, during big 3 meter per seconds of wind-force, wind-force is normal in generator set, the wind-driven generator blowing area of 10 rice diameters is 75M ², multiply by 3*3*3*1.3, be about 1350 kilograms thrust, when wind-force changes, change be not generator but sail, sail changes, generator changes, wind-force still be normal in generator set, spends vertical stablizing so wind-force is 90 with the sail generator set.Rotor diameter was bigger when wind-force blew, and rigidity is big, changed little; Sail is stressed evenly, and is crooked level and smooth, and distortion evenly is level and smooth parabolic shape bending uniformly; Generator set is heavier, keeps can not tilting vertically downward; Generator set is stable.When the excessive rotating speed of wind speed was excessive, 1. fan blade entered in the sail, and blowing area reduces, and did manual work and reduced, and reduced rotating speed.2. drive the alternate generator operation.3. drive the more multipole number operation of generator.4. the wind-force time-delay provides the time assurance for the adjustment of generator.

The wind-drive sail drives generator and adjusts direction automatically, catches wind-force, continuously running.

So wind-force becomes continuous force by discontinuous, and is more stable, the operating time is more lasting, and generator set is stable.

The use of efficiency sail has solved the wind speed problem, can not rely on the development length of blade to solve efficiency but also limit simultaneously us, and efficiency will solve by increasing blade, but the increase of blade not only gains in weight, and also can cause a series of problems.Scheme is constructed fixedly wind wheel of circular shape exactly preferably, with vanes fixed at the circular shape of the generator set of forming by certain diameter fixedly on the wind wheel outer, the rotation of blade, increase and decrease, changing all at circular shape fixedly on the wind wheel, is the rectifier covering in it.Roll up blade on the one hand and increase blowing area, obtain bigger wind-force, increase generated output; On the other hand circular shape fixedly the blade handle number in the wind wheel do not increase mass conservation; Increase the rigidity of blade simultaneously; The generator set stress equalization, stability is better, has reduced manufacture cost; Also provide the basis for the fan blade conversion; When the quantity of blade was above greater than 9, advantage was more obvious.Streamlined recessed direction is identical with the wind-force direction, changes before and after the box haul of generator set position, and wind direction changes 180, the negative side aweather, generator can not reverse, fan blade will use reverse wind-force also can generate electricity.

Safety problem is because blowing area reaches hundreds of square metre [by 400 square metres], f=velocity squared * blowing area * density * speed/2 by formula, and the power of calculating 10 meter per seconds is exactly the 1000*400*1.3/2=256 ton, and sail wind power generator can not have the danger of toppling.But calculate with precedent

1. the stressed direction of sail wind power generator is a normal force, but inner big mouthful of having 7*7*3.14=150 square metre is a funnel form, in fact only has 160 tons.2. be the edge that 160 tons power is distributed as 4 20*3 rice, power is disperseed to can not form body force that each 3 meters edge deforms, vertical blowing area is not 3 meters, but 1 to 1.5 meter.Pulling force is not 40 tons, but 13 to 20 tons, amount to 52 to 80 tons.The 20*3 mean force is 0.3 ton.The pulling force at four edges is under mean force.So below the 4*20*0.5*0.3=40*0.3=12 ton, and inhomogeneous, because strong problem of transmission can not form body force.3. sail is elegant.As 30 degree, 60 degree, blowing area significantly reduces, and pulling force reduces.4. reduce the sail degree of depth, enlarge the wind wheel area.5. even so, very big power is arranged still, we adopt pull bar, self balancing, and counterweight reduces technology maintenance balances such as blowing area.Through practice for many years, take certain measure, can guarantee that the sail generator is perfectly safe, do not have the danger of toppling.

When the sail matrix was deep, the speedup coefficient was big and long two indexs of delay time are all relatively good, but blowing area is big, and wind-force is big, and is relatively more dangerous, and Operation of Electric Systems instability, the degree of depth of sail are wanted suitably, and enough getting final product can not be coveted and be asked high greatly, brings danger.

Classification has front-located mode according to the difference of sail position, and is rear-mounted, simplified style.Sail is positioned at the front-located mode that is before the montant, is applied to the fixed location; Sail be positioned at after the montant for rear-mounted, be applied to temporary facility; Do not have the simplified style that is of montant, use building.

Useful achievement is to place the generating of place, air port by the sail wind power generator that time-honored sail and windmill constitute, the power of blowing strengthens and starts wind-force requirement reduction, delay wind-force decay time, become discontinuous wind-force and be continuous force, increase operation stability, 3, moderate breeze is the long-term proper functioning of energy just, has solved the running problem that more weak wind-force safety continues the high-speed high-power generator set; Effective time is extended to and reaches more than 300 days, and the space is extended to vehicle, and ship on the building, is realized the combination that scene is electric with big rising photovoltaic industry; Cost is very low, and modern design is rational in infrastructure, safeguards simple, safety and environmental protection, pollution-free, lossless.
