Description
Involved in the present invention is a kind of Wing swinging type vertical shaft wind motor.
The inventor has invented this wind energy conversion system in 1976, and obtained English (GB2.082.260) in 1984, beautiful (US4.435.124), method foreign patents such as (Europe 0.046.370).Obtained Chinese patent again in 1988 after improving, the patent No. is 88109991.0.The main feature of above-mentioned patent is, automatic small angle of beat of energy when its fin is in the wind with lee gauge, make the fin angle of attack keep correct angle, so called after Wing swinging type vertical shaft wind motor, wing tip can be thrown off automatically when meeting high wind again, become spoiler, make the wind energy conversion system stall, ride out high wind.The fin deflection angle is controlled by the slide block with V-notch of whippletree end again.Change deflection angle and can change exerting oneself of wind energy conversion system, thereby change the rotating speed of wind energy conversion system, slide block can be controlled the fin deflection angle automatically under centrifugal force and spring action, keeps the wind energy conversion system stabilization of speed, does not change with wind speed and load.Former patent has also proposed to be combined into by the small-power wind energy conversion system scheme of high-power wind mill, and the technology of bamboo rod Truss rib structure or the like.Former invention is in the engineering development process, expose many shortcomings, mainly be that the beat organization distribution is undesirable, noise is big during work, the spoiler area is less, fails to guarantee wind energy conversion system complete off-load when high wind, and the scheme that is combined into high-power wind mill by small wind turbine is unrealistic, because additional supporting structure cost is very high, very uneconomical.Bamboo rod Truss rib structural manufacturing process complexity adds to the cost height, and the rotating speed of wind energy conversion system own is very low, should not directly drive generator, unless adopt special surper-low-speed generator, very uneconomical, not have again to solve and the problem of grid network.
Purpose of the present invention is the shortcoming that exposed at existing patent, develops the anti-high wind of a kind of energy, stabilization of speed is safe and reliable, the efficient height, and simple in structure, cost is low, and is in light weight, can make various large, medium and small types, can be coupled to the wind energy conversion system of electrical network easily.
Wing swinging type vertical shaft wind motor of the present invention, its fin is vertically mounted on the modulator that is fixed in the whippletree outer end, whippletree is inner to be connected with transmission vertical shaft top, fin drives whippletree when the transmission vertical shaft rotates, drive free wheel device by the pin gear speed increasing mechanism that is installed on the transmission vertical shaft, drive the induction generator generating again.This total arrangement is simple and practical, is applicable to various large, medium and small wind energy conversion systems.Solved the wind energy conversion system speedup so that and the problem that connects of generator, also solved problem with grid network.Fin divides the two halves of upper and lower symmetry, passing modulator firmly connects with minor axis, can rotate around the feathering shaft axis CC of modulator by minor axis when meeting extreme wind with the wind, make the basic removal of blast of whole fin, eliminated former patent and relied on the wing tip off-load owing to the little fin that produces of the wing tip area shortcoming of off-load fully.Aerofoil profile adopts the arc center line, and the projection one side is towards the blower fan shaft center line, and this aerodynamic configu ration layout has improved the pneumatic efficiency of wind energy conversion system greatly.For guaranteeing the automatic beat of fin, the fin center of gravity should overlap with beat shaft axis bb, and is in before the fin aerodynamic centre.The whippletree cross section is got streamlined, has reduced resistance during rotation, has increased the pneumatic efficiency of wind energy conversion system.
Modulator is made of flat square tube, movable shell and three parts of speed regulator, flat square tube is fixed on the whippletree outer end, movable shell gusset tab and flat square tube, fin is under modulator is supported, swing around vertical beat axle bb in company with modulator, become from trend different aspect deflection one little angle when being in the wind, make the relative wind angle of attack keep correct automatically with leeward.Speed regulator has the slide block that V-notch and rear end be connected with governor spring by front end and constitutes, and can be free to slide in flat square tube, and the size of fin deflection angle depends on the size of slide block V-notch, guarantees that the wind energy conversion system constant speed rotates.Modulator of the present invention and speed regulator constitute with panel beating and minor axis, have increased intensity and reliability.Speed regulator has rubber seal, has eliminated noise.
The fin first half is made the aerofoil profile fore shell with the glass fibre reinforced plastics casing long tube, thin metal plate buttress brace is arranged in it, trailing edge is made the trailing edge aerofoil profile with thin-walled triangle long tube, with rib fore shell and trailing edge are linked up, cover the rib surface with the glass fibre reinforced plastics film again, to finish whole aerofoil profile external form, this glass fibre reinforced plastic structure fin, good manufacturability, firm and durable, cost is also low.
Fin can rotate freely around modulator by minor axis, but in the minor axis back, also have Second Mate's snak link between fin and the modulator, fin and modulator are firmly fastened when proper functioning, fin can not break away from modulator and rotate freely, can only attached modulator common about an inclined to one side small angle.When wind speed surpassed proper functioning wind speed 20 meter per seconds, the blast of fin surpassed the tightening force that plays semi-annular jade pendant, and snak link is thrown off, and fin just rotates freely and enters feather position, and the removal blast is to guarantee wind energy conversion system safety.Get back to just often at wind speed, can be played semi-annular jade pendant automatically when fin rotates with the wind and fasten, recover normal working.
The overdrive gear that is connected with generator adopts pin gear.The wheel rim that pin gear is made by sheet iron, spoke and stiffening rib and metal wheel hub are formed, and wheel rim inserts more than 100 to 300 equally distributed standard roller with roller bearing and makes the pin tooth.This pin gear velocity ratio is big, simple and reliable for structure, economy and durability very, and being far from general step-up gear can compare, though its mechanical efficiency is relatively poor, can slightly increase wind energy conversion system fin length and turning radius obtains compensation.Business efficiency is much better.
Adopting asynchronous motor and free wheel device to make wind energy conversion system and electrical network hook, is the technology that multiple mechanical battery saving arrangement adopts for a long time, as electric railroad etc., but in wind energy conversion system, because of generally the wind energy conversion system speed adjusting performance is very poor, so can't utilize.Speed regulator of the present invention shows very stable rotating speed in wind tunnel test, so can adopt this technology, this initiates aspect wind energy conversion system.
According to These characteristics, the present invention is 88109991.0 wind energy conversion system compared with the patent No., and safety reliability is better, and efficient is higher, and cost is lower, has bigger use value and economic benefit.Practice proves that also Wing swinging type vertical shaft wind motor can double than the economic benefit of existing wind energy conversion system.This changes the world energy sources structure to the large-scale development wind energy, reduces pollution of atmosphere, and the protection environment is of great importance.
Be described in further detail below in conjunction with the structure and the working principle of accompanying drawing Wing swinging type vertical shaft wind motor of the present invention.
Accompanying drawing 1 Wing swinging type vertical shaft wind motor general structure schematic representation.
Accompanying drawing 2 tab construction schematic representation.
Accompanying drawing 3 modulator structural representations.
Accompanying drawing 4 pin gear speed increasing mechanism schematic representation.
Accompanying drawing 5 free wheel device structural representations.
Accompanying drawing 1 left side diagram general structure of the present invention, be installed on the modulator (2) that is loaded on whippletree (3) outer end by 2,3 or 4 fins (1), whippletree (3) is loaded on the top of transmission vertical shaft (4), pin gear speed increasing mechanism (5) is installed on the transmission vertical shaft (4), link to each other with generator (7) by free wheel device (6) again, wind blows fin (1) promotes whippletree (3) by modulator (2) and rotates around transmission vertical shaft (4), drives generator (7) generating by pin gear mechanism (5) and free wheel device (6) again.Number in the figure (8) is a support.
The plan view on accompanying drawing 1 the right is a wind energy conversion system aerodynamic configu ration layout diagrammatic sketch, fin (1) adopts arc center line aerofoil profile, its projection one side is towards the vertical axle 00 of wind energy conversion system, the fulcrum of fin and beat axle bb overlap, before the aerodynamic center of fin, and feathering shaft axis cc is before beat axle bb, and annular arrow shows the wind energy conversion system sense of rotation.The cross section of whippletree (3) is made streamlined, sees label (9), and its head forward.This aerodynamic arrangement helps improving the efficient of wind energy conversion system.
During the wind energy conversion system proper functioning, snak link on the fin (16) fastens the buckle (27) of movable shell, at this moment fin (1) and modulator (2) and movable shell (22) fix as one, and can together deflect around the shaft axis b-b of beat axle (30) with modulator, movable shell (22).When being in the wind with leeward, fin can both keep the best angle of attack, makes fin can promote wind energy conversion system efficiently and rotates.When wind speed surpasses normal wind speed, blast on the fin is very big, the latch (10) of snak link (16) can be extruded the breach (26) of buckle (27), fin (1) and modulator (2) are thrown off, fin (1) can rotate freely around feathering axis cc under minor axis (13) supporting, automatically under wind-force, change downwind over to, almost make the whole removals of blast on the fin.The suffered blast of whole wind machine significantly reduces, and this makes wind energy conversion system can design very lightly, can guarantee the safe and reliable of wind energy conversion system, but weight reduction again reduces cost.When wind speed Hui Huizheng often, the fin of having thrown off rotates with the wind at random, when entering buckle (27), because of breach (26) both sides buckle end face is smooth circular-arc slope, snak link (16) can be compressed easily, and fin is easy to slip over buckle (27) end face, is then fastened immediately when arriving breach (26).Under normal wind ram compression power, be can not be compressed dropout, very empty because of breach (26) opening angle, guaranteed the reliability of working.
Speed regulator (23) is had V-notch (34) by front end slide block (32) is constituted with the governor spring (33) that links to each other with the slide block rear end, shown in figure below of accompanying drawing 3.Slide block (32) places in the flat square tube (21), can be free to slide in flat square tube, but have governor spring (33) to hold it, can rest on the equinoctial point position of centrifugal force and spring tension.In the time of in flat square tube stretches into movable shell (22), the rubber case (28) of lever (29) just is in the V-notch (34) of slide block (32) front end.When the fin beat, rubber case (28) is move left and right in V-notch (34) just, and the size of fin swing angle depends on the size of V-notch (34).When the wind energy conversion system rotating speed increased, centrifugal force increased, and slide block (32) just outwards moves, and V-notch (34) openings get smaller reduces the beat of wind energy conversion system, and wind energy conversion system is exerted oneself and reduced thereupon, and rotating speed therefore reduces, and returned extensive to original rotating speed.Otherwise it is opposite.This speed regulating method is very effective.No matter wind speed changes, or load changes, and can both guarantee constant rotational speed.
For reducing lever (29), slide block (32) and mutual striking force and the noise of flat square tube (21),, all post rubber gasket (35) in the inboard of slide block (32) outside and V-notch (34).
Accompanying drawing 5 is structural representations of free wheel device (6).Mainly be made up of front axle (60), rear axle (62) and plurality of rollers (61), front axle (60) end has a sleeve pipe (63) to cover an end of rear axle (62).Sleeve pipe (63) inwall is formed by several sections arc-shaped curved surfaces (64), and roller (61) is movable between sleeve pipe (63) inwall and rear axle (62) end.When having only the current axis rotating speed to surpass the rear axle rotating speed, roller is just choked, and front axle could drive rear axle and rotate, and under what its situation in office, rear axle can not promote front axle and rotate.
The present invention adopts free wheel device, makes front axle (60) connect the mill pinlon (51) of wind energy conversion system pin mill pinlon speed increasing mechanism, and rear axle (62) is exactly the rotor shaft of induction generator (7).
Induction generator gets access to grid or diesel generator, when wind speed is little, turn up is during less than mains frequency, and free wheel device (6) is thrown off, motor is a unloaded motor under line voltage drives, and its rotor shaft is that rear axle (62) is with the rotating speed idle running near mains frequency.Therefore when calm or wind speed did not reach work wind speed, the rotating speed of mill pinlon (51) was lower than the rotating speed of idle running motor, so free wheel device is thrown off, wind energy conversion system and motor are independent of each other.The latter is the idle running motor.When the wind speed of wind energy conversion system reached work wind speed, its rotating speed was controlled in the stabilized (steady-state) speed that is slightly larger than mains frequency, and free wheel device (6) engages, and wind energy conversion system drives asynchronous motor, becomes generator for electricity generation by motor, and electric power is imported mains supply.If at this moment electrical network (or diesel engine) has a power failure, then induction generator is powered separately.Under any circumstance, motor can not turn the promotion wind energy conversion system around.
The present invention adopts free wheel device also to solve the energy storage problem, and it is big promptly to have cancelled investment, easily pollutes and safeguard difficult storage battery.Still have electricity to use when calm.
