Description

Wind cylinder type wind power generating device

Technical field

The present invention relates to a kind of electricity generating device, be specially a kind of wind generating unit.

Background technique

Wind is the most familiar natural phenomenon in our daily life, and tellurian wind is that solar radiation causes the earth surface atmospheric layer inequality of being heated, and causes the atmospheric pressure skewness.Under the differential pressure effect, the motion of air along continuous straight runs just forms wind, and the kinetic energy that air flows produced is exactly wind energy.Wind energy is a kind of most active renewable energy sources, therefore we can say that also wind energy is a kind of inexhaustible energy.And the mineral fuel energy such as oil, coal, natural gas in the utilization process, can give off carbon dioxide CO ₂, sulfur dioxide SO ₂, nitrogen oxide NO _xCarbon monoxide CO; dust or the like; cause greenhouse effect; phenomenons such as acid rain; the serious environment pollution and the destruction ecological balance; this makes the ice sheet area of two polar regions, north and south dwindle; the snow mountain snow melt region of Tibet plateau increases, and the ruined area of the overhead ozonosphere in polar region is enlarging, and these have all beaten alarm bell to us; people must utilize reproducible wind energy as soon as possible; solar energy; Wave energy etc.; reduce and use oil; coal; the fossil energy that natural gas etc. are non-renewable, and the exploited quantity of fossil energy is very limited, to human existence; development and energy demand have proposed the serious crisis warning.

Through probing into of field investigation and technical data, recognize that the wind energy resources of our country is very abundant, about 2.5 hundred million kilowatts of developable electric motor power, occupy first place in the world, but our national actual wind-power electricity generation electric motor power only accounts for 0.11% of national electric power installation, the wind-power electricity generation development potentiality is huge.

Use wind electricity generating system more widely at present, for the form of collecting folk songs of cloverleaf in the majority, but along with the generate output of electricity generating device constantly increases, the blade diameter of cloverleaf blower fan must be done very greatly, with the expansion area of collecting folk songs, increase generated energy, calculate according to data, if do the wind-driven generator of 3 megawatts, then its fan blade diameter will reach 100 meters, and purpose is to increase blade tip peripheral speed, wind-connector mounting support pylon, it is comparable to the height of " Washington, DC memorial tower " highly, and promptly total height is 150 meters.This obviously is impracticable scheme.

Present wind electricity generating system, as: cloverleaf, double-valve type, single leaf formula is under strong especially strong wind situation, blade is fractureed easily, when the weak especially gentle breeze of wind speed, because the friction factor resistance from weight and transmission system of fan blade, blade just changes motionless, remain static, when temperature-20 ℃, have the blade embrittlement, faults such as fracture take place.

Present wind electricity generating system, complicated to the tracking technique of wind direction, but the direction of wind is changeable, rotates sometimes.

Summary of the invention

The object of the present invention is to provide a kind of wind cylinder type wind power generating device, can collect the energy in the very weak wind well, simple from the device of motion tracking wind direction, power consumption is few, not even power consumption.

Wind cylinder type wind power generating device provided by the present invention, can realize by the following technical solutions:

Wind cylinder type wind power generating device has wind-drive device, runner, generator, the steering gear, storage battery, it is characterized in that, wind-drive device is the collecting type air duct of typhon shape, and the collecting type air duct is fixed on the rotating disk; The small end of collecting type air duct is equipped with wind vane.

The exhaust outlet of collecting type air duct is rectangle.

Runner is horizontal multiblade impeller.

Wind vane is the tail vane formula, and its useful area is greater than the air duct air-admitting surface.

Wind vane is fixedly mounted on collecting type air duct exhaust outlet afterbody, extends back, and conveniently detachable.

Trapezoidal collision block is set between last lower rotary table, and the restriction angle of yaw is not more than 345 degree.

The first, the collecting type air duct of wind cylinder type wind power generating device is the cylinder that adopts a typhon pattern, enlarge the collection area of intake grill to wind, significantly improve the wind speed at exhaust outlet place, can not only solve the problem that wind can not generate electricity when weak, and under multiple situation, can both use.The design capacity of this wind generating unit is 500 watts, and through calculating as seen, wind cylinder type generator of the present invention improves 11.29 times to wind speed.

$=\frac{\mathrm{\π}{R}^2}{B\×C}\×80\%$

$=\frac{3.1416\&times;{0.562\mathrm{<figure-callout\; id="2"\; label="m"\; filenames="A200810034091E00141.png,A200810034091E00151.png"\; state="\{\{state\}\}">m</figure-callout>}}^2}{0.5m\&times;0.25m}=11.29$

In the following formula, R ²Be (the m of 0.75 meter of intake grill radius ²)

B-be the long limit 0.5m of exhaust outlet rectangle

C-be the broadside 0.25m of exhaust outlet rectangle

η-utilization factor is 80%

The wind speed of design intake grill is 4m/s, i.e. V ₁=4m/s

The wind speed that the wind speed of exhaust outlet equals intake grill multiply by raising wind speed multiple, i.e. the wind speed V of exhaust outlet ₂=4m/s * 11.29=45.19m/s flows through the (m perpendicular to wind speed sectional area A in the unit time ²) wind energy:

Wind energy ω=1/2 ρ V ³A

In the following formula: ρ-be air density kg/m ³

V-is wind speed m/s

A-is the m of sectional area unit ²

ω-wind energy unit is kg, m ², s ^-3(being W)

From above-mentioned wind energy formula W=1/2 ρ v ³A increases swept area of rotor A and can increase the wind energy that is obtained with raising incoming flow wind speed V as can be seen.

Following formula wind energy formula, divided by corresponding area A, just obtain the wind energy density formula, it is air-flow vertical wind energy by unit cross-sectional area in the unit time.

$\mathrm{\&omega;}=\frac{1/2\mathrm{\&rho;}{v}^{3}A}{A}=1/2\mathrm{\&rho;}{v}^3$

Air density ρ is an air pressure, the function of temperature and temperature, and the air density of different regions is all inequality, can table look-up and learn the numerical value of ρ.

Altitude and barometric pressure, atmospheric density relation [15 ℃=288k of atmospheric temperature]

The wind energy of this project air duct exhaust outlet is:

W＝1/2ρV ³A

＝1/2×1.224×45.19 ³×3.14×(0.5 ²—0.45 ²)×1/5

＝1685.59W

In the following formula: ρ---in Shanghai, atmospheric density gets 1.224

V---for after the speed-raising of air duct afflux, the exhaust outlet wind speed

A---be swept area of rotor, this project adopts the cross-flow type multiblade impeller, and swept area of rotor is an annulus, exradius 0.5m, and interior circle radius 0.45m, the area of wind on wind wheel is 1/5 of whole annulus

No matter from above-mentioned wind energy formula W=1/2 ρ V ³A or wind energy density, formula W=1/2 ρ V ³In can see, because of V ³Cause, promptly there is being a spot of increase can cause that a large amount of increases is arranged on the wind speed on wind energy, the method of the air duct collection wind of this Project design increases the air duct air-admitting surface, dwindle the exhaust outlet area, thereby strengthen wind speed and improve multiple, just improve the exhaust outlet wind speed, promptly reached the crucial purpose of amplifying wind speed.

The second, adopt the collecting type air duct of loudspeaker form, its exhaust outlet is made rectangle and is dwindled the useful area of exhaust outlet, so that the wind speed of exhaust outlet improves, and the making full use of of wind energy, remove to blow the cross-flow type multiblade impeller.The friction factor of this impeller is little, light self-weight, long service life, design with this and to overcome that cloverleaf wind energy engine blade is easily fractureed by high wind and the problem that can not generate electricity, cross-flow type multiblade impeller of the present invention, this has determined that also the air duct exhaust outlet is a rectangle, thereby to reach the purpose that coupling fully makes full use of wind energy, the running shaft of this wind energy conversion system is vertical with wind direction.Because dwindling of exhaust outlet area, by calculating as can be known, wind energy density is the key parameter of evaluation wind-driven generator acting ability, wind speed V ₂High more, the wind energy that wind-driven generator may extract is big more, and becomes three cubed relation.

In order when wind speed is low, further to increase distinguished and admirable density, the flow guide device that can change the exhaust outlet size is set at collecting type air duct mid-rear portion.

The present invention can improve the rotating speed of cross-flow type multiblade impeller effectively, improves generated energy with this, increases economic efficiency.

The 3rd, adopt the self method of wind vane, wind vane is fixedly mounted on the tail vane that collecting type air duct exhaust outlet afterbody extends back, and the tail vane useful area is greater than the air duct air-admitting surface.Wind vane is by the afterbody steel pipe that extends back, and erects the square steel of a high 1.5m on framework platform, this square steel top by rope traction in 4/5ths the position of extending steel pipe.More helping rotatable disc is driven by wind vane, make intake grill can both follow the tracks of, aim at the air intake direction all the time, thereby improve the wind energy utilization of wind electricity generating system and improve generating efficiency, substitute the device that follows the wind of present wind-driven generator complexity with this, save the cost and the maintenance expenses of wind energy generating plant.

The 4th, adopt the limit stoper of the steering gear angle of yaw free deflection in the scopes of 345 degree of collecting type air duct, rotated by same direction repeatedly and around the problem of outage line with this connection electric wire that solves the generator that wind generating unit exists.So, can significantly reduce maintenance load, reduce the operating cost of wind-power generating system wind-driven generator.The restriction angle of yaw be not more than 345 the degree collision blocks, be designed to trapezoidal, get its geometrical construction stable properties, the trapezoidal collision block both sides that are provided with on the fixing rotating disk by impact face on the thick yielding rubber of 20mm is set, at the trapezoidal both sides impact face of rotatable rotating disk, yielding rubber just is set no longer.

The steering gear is provided with fixed mechanism, and fixed mechanism is the center by the center of circle with rotating disk on the rotating disk, and the circular hole and the steel Xiao that are miter angle each other form.As long as insert steel Xiao, can guarantee that rotating disk no longer rotates.

Embodiment

For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.

Wind cylinder type wind power generating device has wind-drive device, runner, generator, the steering gear, storage battery, and wind-drive device is the collecting type air duct 1 of typhon shape, and collecting type air duct 1 is fixed on the rotatable rotating disk 5; The small end of collecting type air duct 1 is equipped with wind vane 2.The exhaust outlet 3 of collecting type air duct 1 is rectangle.Runner is horizontal multiblade impeller 4.Wind vane 2 is fixedly mounted on collecting type air duct exhaust outlet, the extended spot behind the afterbody.

One, horn collecting type air duct 1 is used the aluminum alloy material manufacturing, gets little, the cheap characteristic of its density, and coats anticorrosive coating inside and outside air duct, to improve working life.

Two, be coupling cross-flow type multiblade impeller 4, the exhaust outlet 3 of wind energy conversion system is made rectangle, so that the wind energy of exhaust outlet 3 is fully utilized.Because in the geometric figure, the area maximum of circle is so that intake grill is done is circular, to enlarge the collection area of intake grill to wind energy again.Area with dwindling exhaust outlet 3 improves wind speed, has promptly improved the generating efficiency of wind electricity generating system, improves the output quantity of electric energy.

This measure is especially as hydraulic turbine generator, utilize reservoir filling, it is poor to flood, thereby improved the driving force of water,, utilized at little electrical signal of base stage input again especially as transistor to hydraulic turbine generator, just can be at emitter to producing tens times of electrical signal between the collector electrode to hundred times greater than base input signal, reach the amplification of signal, collecting type air duct of the present invention also is based on above thinking, and the collecting type air duct has amplification to wind speed.As everyone knows, if collecting the fan blade blade that wind-force kinetic energy into all is rotated, the intake grill of horn collecting type air duct absorbs, the air of cross-flow type wind wheel back is just motionless so, however air can not stop fully, so the efficient of wind energy conversion system is always less than 1.

Cross-flow type wind wheel power absorbed from air duct can be calculated with following formula: the power of P in the P=1/2CpA ρ V3 following formula-export for wind wheel

Cp-be the power factor of wind wheel

Cp.max＝0.593

A-be swept area of rotor

R-be the wind wheel radius

V-be wind speed

ρ-be air density

Following formula is as seen: the output power of wind wheel and wind speed cube be directly proportional and air density and swept area of rotor are directly proportional, so the diameter of cross-flow type multiblade impeller 4 is designed to 50cm.

Three, adopt cross-flow type multiblade impeller 4 can alleviate impeller from weight and reduce the friction factor of wheel rotation system, and cross-flow type multiblade impeller 4 is firm, is difficult for being fractureed.Impeller adopts the Stainless Sheet Steel manufacturing, rotating shaft is partly closed lubricated with bearing bush, shaft passes through coupling, connect raising speed gearbox and mag-dynamo, because cross-flow type multiblade impeller 4 rotating speeds own are very high,, reduced gear-driven progression so the raising speed scope of raising speed gearbox can be less, thereby reduced the friction factor of system, reduced volume, weight and the manufacture cost of raising speed gearbox.

Four, with reference to Fig. 1, adopt the self method of wind vane, wind vane 2 is fixedly mounted on collecting type air duct exhaust outlet afterbody.The extension tail vane length of wind vane 2 is 2.8 meters, and average wide is 0.95 meter, and the tail vane useful area is greater than air-admitting surface.The stretching, extension tail vane of wind vane 2 is installed on the framework platform, more helping the rotatable dish of going up is driven by wind vane 2, make intake grill can both follow the tracks of, aim at the air intake direction all the time, thereby improve the wind energy utilization of wind electricity generating system and improve generating efficiency, substitute the device that follows the wind of present wind-driven generator complexity with this, save the cost and the maintenance expenses of wind energy generating plant.

Wind vane 2 is simple and practical, wind vane 2 employing aluminum alloy material manufacturings, and can dismantle easily and install.

Five, design limit collecting type air duct deflection angle is not more than the device of 345 degree.Fixedly on the rotating disk, trapezoidal collision block both sides are provided with the 20mm yielding rubber, at the trapezoidal collision block of rotatable disc yielding rubber are not set then.Setting up of limit stoper avoided generator to connect electric wire, around the accident of broken string, significantly reduced the workload of the fault of electricity generating device and maintenance, maintenance because repeatedly same direction is rotated, and reduced the operating cost of wind-power generating system.

Six, because the wind cylinder type current collecting method, so wind speed is had amplification the design's wind generating unit, can reduce the setting height(from bottom) of wind generating unit pylon, save mounting material and expense.

Seven, designed wind generating unit, considered maintenance and the operating technology personnel's when safeguarding safety, two movably gates are arranged near exhaust outlet 3, (when not keeping in repair usually) and wind vane 2 lead jointly when shifting out, play isolated air quantity from the intake grill to the gate during shift-in, just completely cut off the air quantity influence of intake grill exhaust outlet 3.

On fixing rotating disk and rotatable rotating disk 8 diameters being arranged respectively is the identical circular hole of 20mm, and each circular hole spacing is 450, and the center, hole is far from garden plate edge 25mm, as long as circular hole is aimed at up and down, pin is inserted, just can lock the rotation of top rotary table, guarantee maintainer's safety.

At the shaft joint place of raising speed gearbox and cross-flow type fan blade, a brake SC is set, can stop during maintenance and decide the rotation of cross-flow type fan blade.

For making things convenient for maintainer's work, on fixed platform, extend the inspection platform of a steel structure, its podium level design to satisfy the maintainer of 1.65 meters heights, stands on the platform, and reaching out one's hands conveniently to touch any parts of required maintenance.Maintainer's working platform will design security guardrail.

More than 4 points, for maintainer's safety operation is provided with.

Eight, with reference to Fig. 5, the electric energy that the permanent magnetic DC generator sends to charge in batteries, becomes the inverter that exchanges through direct current, again to the AC energy of AC network delivered constant frequency.The supply consumer uses, and in electric control system, is provided with the additives for overcharge protection of storage battery and the over of storage battery simultaneously, to prolong the working life of storage battery, guarantees the normal operation of system.

The maintenance of air duct generator suspends (manually) state.

Hand switch is as selecting the halted state of TD closure, relay FA1, FA2 and brake contactor SC adhesive simultaneously, FA1, FA2 start direct current motor respectively, choke moved in air duct, move into, when moving on to touching lead limit switch FB3, FB4, the break contact of FB3 and FB4 disconnects, and motor shuts down, and this moment SC still adhesive is to brake motor coil power supply, break is to the coupling braking brake of cross-flow type wind wheel and raising speed gearbox.

Overhaul the hand switch that finishes and select the ED closure, disconnect TD simultaneously, the SC outage, its contact disconnects, and stops the brake coil power supply, and brake is unclamped.

The ED closure makes the air duct electricity generating device enter relay FA3 normal operating condition this moment, FA4 adhesive, starts direct current motor respectively, and reversed polarity powers to direct current motor, and choke moves and shifts out outside air duct.FA1, FA2 break contact disconnect when moving on to touching lead limit switch FB1, FB2, and motor is out of service.This moment, air intake and air-out connected.

Nine, because wind power generating set is installed in the field; therefore should take the counter measure to thunderbolt; wind power generating set is protected; in the truss foundation construction, along ground copper conductor is installed, (in the radiation 10m scope) 1 meter dark underground burying underground around ground; satisfy the standard of grounding resistance to reduce earth resistance less than 10 Ω; and at fixing rotating disk place 50mm2 copper conductor, draw down along truss, connect the underground anti-lightning strike ground connection copper bar of burying underground.

Ten, at exhaust outlet 3 places of collecting type air duct inside, this AH guiding device of design wind direction flow guide device AH is one of important behave of the present invention.Its effect:

One causes the useful area of exhaust outlet 3 to dwindle, and wind speed is strengthened, and it is mobile to cause wind direction to upwarp in air duct, can make exhaust outlet 3 wind directions aim at the above radius position of cross-flow type impeller center line like this.The secondary of minimizing wind between the blade of cross-flow type impeller passes through and promptly reduces the damping function of wind in impeller.From the calculation Design principle as seen, cross-flow type wind wheel cube being directly proportional of power absorbed and speed from air duct as long as wind speed improves very decimal magnitude, just can obtain the very big quantity increase of power output.This is the essential idea that the present invention is devoted to improve wind power generator efficiency.

Its two, the design kinetic energy of wind in the collecting type air duct upwarps mobile, can have better self-starting performance, more the highland promotes the rotational speed of cross-flow type impeller, there is bigger moment to go to drive DC generator, improves the efficient and the power output of this wind generating unit, guarantee higher generated energy.

11, referring to Fig. 3, the design's wind cylinder type wind power generating device, calculate to set with the wind 3 and can both normally move generating near gale, and can guarantee good self-starting, in low air density area, for example plateau section, the area, savanna savannah in the Xinjiang and the Inner Mongol or the like, still can reach rated power output, in the rated wind speed scope, output power can keep relative stability.But when wind speed is greater than 7 grades sometimes, can cause output power to surpass the design permitted value, be located at the pneumatic speedometer on the air duct generator fixed platform this moment, can send the logical order signal, the DL closure starts AK1 to AK6 direct current motor, and the window of removing air duct generator front portion moves door, with shunt method, reduce the air quantity that high wind is blown into the air duct outlet port, guarantee the normally generator operation stably of native system, and the stable and safety of a whole set of air duct electricity generating device.Air duct electricity generating device of the present invention is suitable for the above different wind-resources area of rated wind speed scope and rated wind speed, and can be lifted at the low and balance super problem of generating electricity in winter of generated energy in summer.

The logical circuit of wind-force speedometer is set wind-force sky DL closure in the time of 7 grades, wind-force is the DH closure during less than 7 grades, speedometer DH closure, to whole six direct current motors power supplies of AK1 to AK6, motor turns round clockwise, closes whole six fan shunting windows and moves door up to moving the distance that door moves, touching limitation travel switch LB, its break contact is disconnected, and 6 direct current motors just shut down.Wind-force is during greater than 7 grades, and speedometer contact DL closure makes D.C. contactor DN adhesive action, the adhesive of DN, disconnect two couples of normally closed interlock DN1, DN2 simultaneously, connect two couples of normally open contact DN3, DN4, six direct current motor AK1 to AK6 are carried out the reversed polarity power supply, direct current motor turns round counterclockwise, open whole six fan shunting windows and move door, when six fan windows move door, when moving on to the normally closed limit switch RB of touching, D.C. contactor DN loses power supply and disconnects, and AK1 to AK6 direct current motor shuts down.

Owing to move the unlatching of door, removed original touching to limit switch LB, LB resets to closed state again certainly, for the work of next time is got ready, same principle, as move door and close, having removed touching to original limit switch RB, RB is again from resetting to closed state.

12, the air duct collecting type electricity generating device of this project, because the rotating speed of cross-flow type multiblade impeller 4 is very high, between 800～1100r/min, and the rotating speed of generator is 1500r/min, so the speed ratio of the raising speed gearbox of configuration is very little, greatly reduce the cost and the weight saving that the volume that has dwindled gear-box installs whole collecting type air duct 1 of gear-box, help wind vane 2 drives and rotate freely.

13, the manual halted state of air duct electricity generating device

The closed TD switch of maintainer's this moment; motor shift-in FAR1 and FAR2 move door; the intake grill of blocking-up air duct send electricity to carry out the electrical equipment brake to braking brake to the influence in exhaust outlet 3 zones simultaneously, launches with the safety of guaranteeing service work; maintenance finishes; disconnect time-out machine switch TD, remove the working power of brake, the closed normal run switch ED of starting; make choke move door and shift out, air intake and exhaust outlet 3 are connected.Treat that choke moves door and shifts out and put in place, limitation travel switch FB1, FB2 cut off the electricity supply automatically.This moment limitation travel switch FB3, FB4 recovers closed state, for action is next time got ready.

The direct current that generator sends, battery pack is charged, and control inverter converts the direct current of battery pack output the Ac of 220V50 hertz to, and offers electric consumer, present most producer all adopts controller and the incorporate scheme of inverter, and tube claims " control inverter ".

The protective function of control inverter has: 1, to the additives for overcharge protection of storage battery, when wind speed continues higherly, charge in batteries is very sufficient, and when accumulator battery voltage surpassed 1.25 times of voltage rating, controller stopped to charge in batteries, and unnecessary electric current flows to unloader.2, to the over of storage battery; work as wind-driven generator; be in the lower situation of wind speed for a long time, the charge in batteries deficiency, accumulator battery voltage is lower than 85% o'clock of voltage rating; inverter quits work; no longer outwards power supply is when wind speed increases again, when accumulator battery voltage returns to 1.1 times of voltage rating; inverter is resumed work automatically, outwards power supply.

Because the intermittence and the unstability of wind energy, if electric consumer is directly powered by wind-driven generator, power supply can occur cuts in and out, phenomenon fluctuated, this electric energy can't use, and is stable for setting up a power supply voltage, the power-supply system of balanced power supply can round-the-clockly be provided, just must between wind-driven generator and electric consumer, energy storage device be set, the electricity that wind-driven generator sent is stored, stably power to electric consumer.

Desirable energy storage device should have big energy storage density and capacity at present, and storage and power supply have good reversibility, and high conversion efficiency and low transition loss are arranged, and good and economic and long working life are arranged, and is convenient to control and maintenance.

In this wind cylinder type direct current wind powered generator system, when application diode DH prevented that battery tension is higher than generator voltage, storage battery can be blocked by the unilateral conduction the subject of knowledge and the object of knowledge of diode the possibility of generator powered.
