Description

One axis multimachine aerodynamic decelerator single armed of jack-post structure rises resistance and combines vertical axis windmill

Technical field

The utility model belongs to field of wind energy utilization, is related to vertical axis aerogenerator technology, and in particular to a kind of jack-post The liter of structure hinders mating type aerodynamic decelerator vertical axis windmill technology.

Background technique

Vertical axis windmill is most ancient machine, the wooden wind energy conversion system of the sail type of ancient Chinese is not trunnion axis but Vertical axis, be that the mankind made contribution as the European wooden wind energy conversion system of trunnion axis oar blade type.It is horizontal to the wind-power electricity generation epoch Axis machine becomes a star, no matter several hundred, several kilowatts, so that several megawatts, flat axis machine technology is all mature, perfect product of being formed High volume applications.And vertical axis aerogenerator is passed by decades, and it is but bumpy all the way, without mature, perfect product.It divides It is several below:

The Φ type machine (i.e. Dari eritrea type, English name Darrieus) of bent blades.There was large-scale curved leaf in North America decades ago The top drawstring of piece, generator landing formula, wind wheel pattern be it is olivary, also once operation generates electricity hours up to ten thousand.This technology Route has many defects, such as is unable to self start, has dropped out application.The top dragline type Φ type that China occurred is large-scale The explorative experiment model machine of machine, does not continue down after being destroyed in strong wind yet.People transfer to walk independent post type (no top drawstring) Φ type machine route.Φ type machine is actually with leaf for arm.But evolution is for many years, and independent post type Φ type machine only has 10kw is below to have Business application is more common in 3kw and below.It is more several hectowatts, in conjunction with resistance wheel, it is easy to self-starting, power generation effect Fruit is good, is initial success.But due to not having aerodynamic decelerator device, failure is often met under high wind speed area, storm wind.This machine Type is coaxial straight drive, an axis single cpu mode, i.e. direct-connected 1 generator of wind wheel.The vertical axis machine product of initial success, also can only Say it is to temporarily get application in not perfect, immature.

Prismatic blade H-type machine.Numerous producers pursues the technology path of this double support arm multiple-blades (mostly 5 blades) and goes out Produce product.Its transmission chain is that wind wheel is directly fixedly connected with generator shaft (and vertical), i.e., the single cpu mode coaxially directly driven. This transmission chain pattern can be described as by trunnion axis power traction from, and trunnion axis machine is all one machine mode of an axis, middle-size and small-size level Axis machine is exactly that wind wheel is directly fixed on generator shaft.Present most of vertical mechanism shaft persons of making are also that lifting wind wheel is direct It is fixed on generator shaft, equal to using generator shaft as the base support component of wind wheel.The type of this construction is difficult to do greatly, only See and be applied to several kilowatts of scales, and runs generating effect and be not so good as Φ type machine.The commodity machine for 10kw or more scale that so far there are no is good Good application.

The irreplaceable advantage of vertical axis machine is that it is not required to wind, and any direction carrys out wind or no matter how wind direction changes all It can rotate, without to blower structure；And trunnion axis machine must be to wind, minicomputer is by tail vane, medium-and-large-sized machine by complicated Yawing mechanism To wind.On generating dutation, vertical axis machine does not lose windage loss, and trunnion axis machine has when wind direction changes frequent to windage loss mistake.

It is most concentrated although vertical axis machine research and development in recent years in Chinese flourishing expansion, become release vertical axis model machine in the world Country, at the same time in the world also without there is testing machine, commodity machine than the more advanced more perfect maturation of China, but China goes out The existing curved leaf machine of lift-type Φ type, the straight piece machine of H-type, function are all still not perfect --- and there is no aerodynamic decelerator device, and has in structure Bottleneck, limitation are done big.It is nearly all the biography of wind wheel with directly fixed, the coaxial single machine of generator shaft as commodity selling Dynamic structure, is all minicomputer, rarely has and releases power scale greater than 10kw or more person, generally hovers in several kilowatts of ranks.

Lift vertical shaft machine, a component --- the tangential force of the lift generated by streamline vane in airflow function It pushes blade to rotate around vertical axis, therefore claims lift vertical shaft machine.Blade dynamic mechanism is similar with trunnion axis machine blade.Lift-type Each lift-type blade of vertical axis machine is rotating a circle in interior most of angle all dynamic (i.e. positive tangential force), this makes wind Wheel can be continuously run.Only it is different wind wheel design (such as blade width, the number of blade, support arm design, wind wheel radius size, the wing Type selection, ways of deceleration, the design of uprising wind energy power etc.) making wind mill performance, (such as starting wind velocity, rotary speed property, band carry Ability, efficiency, control performance) there is very big difference.

It is all directly to be pushed away using wind pressure generation whether with wind scoop or sail as simple resistance-type vertical axis machine Power is rotated by the wind scoop torque difference of vertical shaft two sides, and rotating a circle, it is dynamic within the scope of 180 degree to be only less than, and another half cycle is It is motorless.It is to belong to the not improvable of principle, and there are many component, cost is excessively high, simple resistance-type due to its low efficiency Wind wheel is difficult to promote and apply, and this will not be repeated here.

Summary of the invention

Technical problems to be solved

The purpose of this utility model is to solve many disadvantages on existing lift vertical shaft wind turbine technology.For Find from Development Practice, the Practical Project problem present in is, and it is an object of the present invention to provide a kind of novel lift-type is vertical Axis wind energy conversion system: no matter small-sized, medium-sized or large-scale, no matter that is, from several kilowatts to tens kilowatt, or several hundred kilowatts or more are arrived, all It has been allowed to a kind of reliable and simple structure, to have allowed vertically holding up, major diameter is bigger (then force-bearing situation is severe greatly for draw ratio) And the vertical axis that rotates again can the horizontal excitation power of resistance, i.e. tilting moment in addition to that can transmit that torque also wants.Existing prevalence Straight leaf both arms H-type vertical axis machine, wind wheel are directly fixed on generator shaft, and generator shaft is subjected to the torque of wind wheel transmitting, also Support wind wheel weight and powerful tilting moment.Although the benefit of this structure is apparent --- extremely simple, part is small It is skilful and simple, it is at low cost, but generator shaft and its bearing and shell bear additional load, and they are not also subjected to big Combined load, this unreasonable structure are also done less by this structure.

Existing prismatic blade both arms H-type vertical axis windmill, low wind speed (such as 5m/s or less) do not start, middle wind speed (such as 5 ~10m/s) turn unhappy, and rated wind speed (such as 12~13m/s) is far not achieved full hair, when higher wind (14~15m/s or more) Horizontal thrust is very big, and axis top is shaken horrible.In order to which low wind speed can start, many producers using multiple-blade (such as 5 leaves, even Have 8 leaves), but problem and do not solve, middle wind speed or generation deficiency, efficiency reduces.There is problem in a word is exactly starting difficulty, Generation deficiency can be attributed to low efficiency.Here low efficiency is not that vane efficiency is low, but entire wind wheel low efficiency.Existing production The support arm of product, prismatic blade is unreasonable, have in terms of section configuration it is elliptical, circle, have crescent even there are also square tube, sweep It is big to plunder air drag；It is both arms in terms of support arm pattern, there is transverse arm, oblique arm, there are also various vertical and horizontal rod piece support arms, arm is more Interference blows to the air-flow of blade, increases the diclinic support arm that rotary inertia, especially root are intersected in a bit, more interference air-flow.

Existing vertical axis machine does not have aerodynamic decelerator, brakes by electromagnetism, mechanical reduction, 16m/s or more wind speed can only be shut down. Mechanical brake is naturally also necessary, but coaxial direct drive structure setting can only generally take disc brake, realize machinery with brake clip Brake, brake clip movement generally by it is hydraulic can be achieved it is automatically controlled (unattended), but with the standing-meeting of minicomputer equipped hydraulic increase cost, and The minicomputer of no hydraulic station just can only manually operate brake clip.Coaxial direct drive structure will be more complicated with a set of disc brake apparatus , especially on minicomputer if with it is hydraulic be very uneconomic.

To solve the above problems, allowing vertical axis machine comprehensive and reasonable, improvement: changing structure and generator shaft should only be turned round Square；Generator answers speedup, rather than coaxially rotates at the same speed with wind wheel；Both arms support prismatic blade is changed to single arm support blade, reduces It scans resistance and reduces entire wind wheel rotary inertia, be conducive to wind wheel and accelerate；It installs aerodynamic decelerator device additional on prismatic blade, improves and hang down D-axis machine performance；To straight blade lifting wind wheel plus match resistance-type wind wheel, makes wind wheel be easy to start, make mechanical brake simple, low Cost.

To achieve the above objectives, the present invention adopts the following technical solutions:

A kind of one axis multimachine aerodynamic decelerator single armed of jack-post structure rises resistance and combines vertical axis windmill, by lifting wind wheel and resistance Power type wind wheel, which is coaxially constituted, rises resistance mating type wind wheel；Jack-post structure is made of outer shaft, inner prop and coaxial bearing, cylinder is rotation Rise the supporting member of resistance mating type wind wheel；Deceleration spoiler is constituted by leaflet section 13；One axis is constituted by gear wheel 8 and pinion gear 9 Multimachine speedup mode, generator 10 are fixedly connected with brake 14, it is characterised in that: the lift-type blade 1 and leaflet section 13, lifting wind wheel is constituted with the horizontal support arm 2 of blade；Upper layer wind scoop 4 and lower layer's wind scoop 5 constitute resistance-type wind wheel, lift-type wind Wheel and resistance-type wind wheel, which are coaxially fixed on lower axle 7 and are formed to rise, hinders mating type wind wheel；It is directly connected to constitute by upper axis 3 and lower axle 7 Outer shaft constitutes jack-post structure by upper bearing (metal) 12 and the rotation connection of lower bearing 11 with cylinder 6.

The one axis multimachine aerodynamic decelerator single armed of jack-post structure rises resistance and combines vertical axis windmill, it is characterised in that leaflet Section 13 is distributed in the upper/lower terminal of primary blades 1, is rotatablely connected with 1 end of primary blades, leaflet section 13 and 1 initial relation of primary blades For 0 ° of coincidence relation, and can be swung in 0~90 ° of range-controlled.

The one axis multimachine aerodynamic decelerator single armed of jack-post structure rises resistance and combines vertical axis windmill, it is characterised in that horizontal branch Arm 2 is horizontally disposed, single arm support blade 1, and the section of horizontal support arm 2 is fairshaped fish shape shape.

The one axis multimachine aerodynamic decelerator single armed of jack-post structure rises resistance and combines vertical axis windmill, it is characterised in that power generation Machine 10 and lower axle 7 and upper axis 3 be not coaxial, and gear wheel 8 is fixedly mounted in lower axle 7, can drive multiple pinion gears 9, and pinion gear 9 is fixed It is connected to generator 10.

The one axis multimachine vertical axis windmill of jack-post structure, it is characterised in that brake 14 and generator 10 is same Axis connection.

Beneficial effect

Since generator is not fixedly connected with wind wheel, generator shaft is just solely subjected to torque and is not subject to other any from wind The complicated various load of wheel, the various complex loads of wind wheel are assumed responsibility for by cylinder, and cylinder have it is more much bigger than generator shaft Module of anti-bending section, can more undertake various complex loads especially horizontal thrust.By jack-post structure, revolutionize existing The wind wheel of H-type vertical axis machine type there are modes, improve the load of generator shaft.This jack-post structure, is suitable for any The vertical axis machine of power, is more suitable for high-power vertical shaft machine.This is provided for the sizing of vertical axis windmill of different sizes can Row mode.

One axis multimachine mode gives generator speedup by gear, can thus use the motor of higher nominal revolving speed, and High-speed motor is more at low cost than slowspeed machine, small in size, light-weight.One axis multimachine mode also helps control wind speed round: working as wind When speed is lower, blade power is low, and wind wheel is not easy to accelerate, and at this moment can reduce generator electromagnetic resistance --- pass through robot control system(RCS) It allows wherein one (or 2) generator to be detached from load, is in light condition；When wind speed height to a certain extent or wind speed round promoted After to a certain extent, then no-load generator band is enabled to carry；One axis multimachine mode generator easy to repair, dismantle fault generator when not Wind wheel must be dismantled, this greatly reduces maintenance cost, and it is (on the contrary in coaxial straight drive, i.e. one machine mode of an axis to greatly facilitate maintenance In, detachable maintaining generator must dismantle entire wind wheel), in operation one it is faulty when not generating electricity, exist there are also other generators Work, not will cause driving.

This technology is lighter than existing double support arm wind wheels, rotary inertia is lower using single support arm, and wind wheel rotation will be made lighter Fastly, be conducive to low wind speed to start, while reducing wind wheel self-energy consumption in operating, also mean that increase output energy, mention High efficiency.Support arm uses streamlined section, such as fish shape, there is the resistance coefficient of very little, reduces support arm and scans resistance, this is raising again Efficiency increases a contribution.Support arm is placed between upper layer and lower layer resistance wheel, and horizontal thrust position is also just herein.Horizontal thrust Position is multiplied by column root distance, i.e. column institute bending moment, that is, tilting moment, being arranged can allow cylinder unlikely excessively high herein, To lower horizontal thrust moment of flexure caused by cylinder.

Configuration resistance wheel can help the low wind speed of wind wheel to start, this is because resistance wheel have even if low wind speeds it is larger Torque.When more than higher wind (such as 14,15m/s), lift-type blade power output is very strong, and entire wind wheel only leans on Lift wheel just to make machine Tool can be output to very strong stage, and generator is also at full hair, super generating state, and that at this moment it is desirable to wind speed rounds is restricted, no It is promoted again, and at this moment the edge linear velocity of resistance wheel without power will be turned in tow by Lift wheel close to even more than wind speed, Like fan, at this moment resistance wheel automatically becomes the burden of entire wind wheel, this is just conducive to limit entire wind speed round.By resistance Wheel is divided into two layers, and two layers of resistance wheel relationship in 90 ° that intersects, against four direction, carrying out wind from all directions can all push away wind scoop mouth The rotation of dynamic resistance wheel.

Blade upper and lower ends setting can bucket segment can realize aerodynamic decelerator.Usually (when wind speed round is no more than rated speed) Can bucket segment and fixed leaf section one, be a part of fixed leaf；When wind speed round is more than rated speed, needs to control revolving speed When, can bucket segment open rotation one angle (robot control system(RCS) offer instruction), maximum can turn 90 °.Can bucket segment open when wind wheel Running resistance sharply increases, and wind wheel is forced to slow down.

Since the utility model takes an axis multimachine mode, mechanical brake can be realized with very simple mode, be powered just Generate brake, it is easy to it realizes and automatically controls, i.e., install electromagnetic brake in generator shaft, structure is simple, and it is effectively reliable, It is low in cost.

Above-mentioned measure can be brought: more reasonable rotating shaft support and its drive mechanism, so that vertical axis machine structure is simple, logical With change；It can low wind speed starting；Raising efficiency；Effectively control revolving speed；It is easy to repair.A kind of simple and reliable and general jack-post knot Structure, and be conducive to significantly reduce manufacturing cost.By above-mentioned technology layout, it can be achieved that the utility model described in summary of the invention it Purpose.

In order to illustrate beneficial effect, spy does following analysis and proof:

Wind wheel is directly fixed on generator shaft, bring strength problem:

It is straight no matter wind wheel is fixed with what mode first, it should be understood that wind energy conversion system power and wind wheel size defer to certain relationship It connects and is fixed on generator shaft, or be rotatablely connected using jack-post structure, by wind wheel and cylinder, diameter, the length of blade of wind wheel are big Body is the same, and horizontal thrust (power of destruction is generated to wind wheel) is the same, effect of the horizontal thrust to rotor shaft Point is same.

It is analyzed with designing example: the vertical axis windmill of one 4kw of design, about 3 meters of the height (axial length) of rotor shaft, Horizontal thrust acts in the middle part of axis, and at about 1.5 meters, i.e., 1.5 meters of torque arm length, horizontal thrust are 3000 Ns；Assuming that taking wind wheel The structure of direct-coupled generator, 60 revs/min of generator rated speed, axis normal diameter is 50mm, solid shafting；Simply to check wind Wheel shaft Root Stress:

Solid axial stress

Note: this solid shafting uses Fine Steel Casting iron, yield limit 400MPa.

Since rotor shaft and generator shaft connect together, this stress is exactly the stress of generator shaft.Original generator shaft It is completely adequate for undertaking torque, but at this moment also to undertake moment of flexure, and stress is laid in not only without instead more than 1.38 Times, it is not competent.

Jack-post structure (wind wheel is not direct-connected with generator shaft) is seen again:

Common low-alloy carbon steel can be selected, yield limit only has 235MPa (lower than the strength of materials of generator shaft), Wind wheel size, point of force application, horizontal thrust etc. all as upper example, difference be it is present select steel pipe, cylinder outer diameter is 168mm, to check intensity:

Steel penstock stress: it uses structural steel (low-alloy carbon steel), yield limit 235MPa

It uses steel pipe and increases the outer diameter (column that this example outer diameter is 168mm) as wind wheel supporter, at wind wheel root Body stress only accounts for the 19% of material allowable stress, considerably increases safety.Accordingly even when horizontal thrust increases in high wind speed Add, it can also be safe to use.And existing popular wind wheel and the direct-connected structure of generator, the level for being unable to undergo to operate when high wind speed push away Power, the wind speed of more than ten metre per second (m/s)s will stoppage protection, mustn't operate.

Add the necessity with resistance-type wind wheel: lift-type is when blade is static, without resistance wheel, as long as wind speed reaches certain Degree, lift-type blade can also move up, this is " resistance starting ".After starting, accelerates with slow, just have the increasing of lift Add, the tangential force (power that is required, making blade rotation) on blade just will increase.But this needs higher wind speed.And it sets What meter wind energy conversion system was pursued is that low wind speed starts, low wind speed generates electricity, and simple lifting wind wheel is exactly unsatisfactory for this requirement.Merely The characteristics of lifting wind wheel is that torque is small, but the kinetic energy carried after rotating is big.And the characteristics of pure resistance-type wind wheel is torque Low, the entrained kinetic energy of larger but revolving speed is small, in low wind conditions, it may have preferable starting capability.Pure lift-type wind In conjunction with pure resistance-type wind wheel advantage, the wind wheel for rising resistance mating type can be achieved with low wind speed and starts wheel.S form-drag wind wheel, Europe Human hair is bright to have 80 years history so far, has been demonstrated to work well in the fixed resistance-type wind wheel of wind scoop, also answer till now With.

Vane arm uses fish shape section, makes comparisons with using round tube.Object aerodynamic Drag Calculation formula:

Fd --- air drag, ρ --- atmospheric density, V --- wind speed (air velocity), C_d--- resistance coefficient,

S --- wind area (being the front face area of arm here).

Assuming that wind speed is calculated by common rated wind speed 12m/s, the arm and round tube of fish shape section make the comparison of resistance of vane arm, generation Enter to calculate:

Note: the air-flow of the aerofoil profile of fish shape section, string and obstruction operation is at 0 ° of angle of attack, resistance coefficient 0.008；Cylinder The resistance coefficient of shape (steel pipe) is 1.2, and caliber is set as fish shape section thickness here.It can be seen that the arm of fish shape section scans Resistance is much smaller.The design uses single arm support blade, and sweep air resistance reduces one times again.And rotary inertia also significantly subtracts Small, necessarily accelerating wind wheel, fast, rotation is brisk.

In terms of aerodynamic decelerator: aerodynamic decelerator should be wind energy conversion system indispensability performance, therefore without the wind energy conversion system of aerodynamic decelerator function It is incomplete wind energy conversion system.In existing wind energy conversion system product, trunnion axis machine is all with aerodynamic decelerator device (measure), such as variable pitch tune Speed, blade tip clap slow down to operation, yaw speed limit, inclined head are wagged the tail the measures such as speed limit (minicomputer)；Vertical axis machine cannot become because of blade Paddle and does not solve the problems, such as using the change of vane aerodynamic always come speed limit so that vertical axis machine is not that driving occurs to break Bad, exactly 15,6 meter per second wind speed are locked not to generate electricity and wastes generator meeting good greatly.Existing vertical axis, which is not bold enough to do, also greatly this side Face reason, because existing vertical axis machine only has electromagnetic brake, mechanical brake, and electromagnetism, mechanical brake are high under middle high wind speed Brake is to stop incessantly when speed operating, and risk of braking by force is big, easily directly destroys parts.Mechanical brake is generally used for pneumatically After deceleration, wind speed round brakes again after lowering.This of existing vertical axis machine not perfect limits its popularization and application.This Utility model be exactly be exactly to generate in this context.The both ends of prismatic blade are taken that a bit of be designed to can by the utility model Bucket segment, such as Fig. 1, Fig. 6, in 13 be movable leaflet section, 90 ° can be opened to from 0 °, can also invert return.Wind wheel in Fig. 1, Fig. 6 Situation that the left side indicated be movable leaflet section and primary blades 1 are integrated, when normal operation, are completely coincident, i.e. 0 ° of return Situation, at this moment leaflet section 13 is called " waving to operation "；Indicate on the right of wind wheel be movable leaflet section 13 open, with primary blades 1 not The situation being integrated, at this moment leaflet section 13 is called " clapping to operation " situation.What Fig. 2 was indicated is up situation, leaflet section 13 wave to operation；What Fig. 5 was indicated is limiting operation situation, and leaflet section 13 is clapped to operation, and on the tangent line of wind wheel rotational circle is The situation of primary blades 1, on wind wheel rotational circle normal is the posture situation of leaflet section 13.When leaflet section 13 clap to operation when, Its air force property is spoiler, can be considered a plate, the resistance coefficient of plate is about 2, by formulaSpoiler, which produces to rotate wind wheel, generates high resistance, and drag size is in addition to the quadratic power with wind speed V It is directly proportional, it is also directly proportional to flow-disturbing plate suqare, only it is to be understood that spoiler area S can calculate spoiler resistance.Spoiler is (i.e. at this time Clap the leaflet section to operation) air drag it is more many times larger than primary blades air drag, on resistance coefficient just difference 250 times, Leaflet section calculated by formula 1 clap wave to running resistance, primary blades to running resistance:

Note: this design example leaf chord length (blade is wide) is 0.3m, and blade thickness is 0.054m, main lobe length of a film 2m.

Although area accounting very little is once clapped to operation, and resistance can compare main lobe as it can be seen that leaflet section is only a bit of Piece resistance is 100 times big, so big flow-disturbing resistance, it is sufficient to allow wind wheel to slow down, have significant speed limit effect.Leaflet section is beaten The time course opened can be designed to the several seconds, slowly open rather than moment rapidly opens, so that deceleration have one it is reasonable Transient process avoids the impact to wind wheel each component and transmission device.The opening of leaflet section withdraws and uses motor drive, Motor is controlled by robot control system(RCS).

The utility model mechanical brake uses electromagnetic braking mode, brake guaranties, and frictional disk is attracted, and brake can be realized Vehicle.
