Description

The vertical shaft moving vane wind-driven generator

Model utility relates to a kind of device that develops wind energy, is a kind of wind-driven generator.

Existing wind-driven generator, its rotor shaft are the horizontal axis that substantially horizontal is arranged, and the exhaust angle of blade is fixed: generator is with many rotor and many stator structures that pole coil is formed to magnetic pole.There is following shortcoming in it: (1) horizontal shaft type wind wheel takes up space big with floor space.Because wind wheel needs the four sides rotation to accept all directions wind energy of the wind comes from, the space range of being skimmed over during the fan blade rotation can not have any obstacle.So must provide enough space and floor area to be the special use of construction wind-power electricity generation.

(2) the wind tower is had relatively high expectations.Because fan blade rotates up and down, do not touch the safety that ground object and people hold when making rotation, the fan blade lower end built on stilts of must trying one's best, so the wind tower must be done higherly.And because fan blade rotates up and down, do not allow with cable wire the wind tower to be reinforced, and can only lean on the intensity of wind tower self to resist wind-force, therefore, the wind tower must be done not only tall and big but also solidly.

(3) the wind wheel wind-engaging is inhomogeneous.Because wind-force is uneven in vertical direction, general eminence wind-force is bigger, and lower wind-force is less, and wind wheel wind-engaging active force is that top is big, and the bottom is little.Rotor shaft will bear very big side direction torsion, and therefore, rotor shaft and bearing must be done very big very solidly equally.

(4) generator cost height, volume is big, complex structure.Because generator is many magnetic poles tandem permanent magnet generator, for the mechanical variable speed device that need not fall behind, it gets up with many group pole coil series aiding connections, and with the output voltage that is multiplied, this has increased cost, volume and the weight of generator greatly.

More than 4 determined that the cost of this wind-driven generator is very high, volume weight is also very huge, for the investor, too high cost of investment will make returns of investment cross low and investment risk strengthens, excessive volume and weight has increased great difficulty for transportation and construction, so can not become popular wind-driven generator.

Summary of the invention: apply to vast power outage area and economic backward area for wind-driven generator can be popularized, must make a kind of not only economy but also practical wind-driven generator.It is low that it must possess cost, the efficient height, and volume is little, stablizes durablely, and easy care adapts to characteristics such as big or small wind speed.At the various shortcoming of above-mentioned wind-driven generator, the utility model proposes a kind of vertical shaft moving vane wind-driven generator of combination, it is low that it has possessed cost, the efficient height, volume is little, stablizes durablely, and easy care adapts to characteristics such as big or small wind speed.

Figure 34 is the outline drawing of Figure 32 and two kinds of electronics automatic synchronizations of Figure 33 combining inverter.

As shown in Figure 1, the leaf blade 1 among the figure is fixed on the sharf 3, and sharf links to each other with fan blade spiral arm 7 by blade bearing 2.The blade arm of force 4 that rotates together with the axis is housed on an end of sharf, in fan blade spiral arm both sides and adjacent with the blade arm of force 4, fixing brute spring 5 and weak spring 6, an end of fan blade spiral arm is fixed on the wind wheel dish 9 with bolt 8, and they form a complete fan blade jointly.

There is the same structure fan blade of four symmetric arrangement to constitute a wind wheel among Fig. 1, the composition of each fan blade is all identical, and each fan blade all is fixed on the wind wheel dish 9 by a fan blade spiral arm 7 and rotates with wind wheel, and wind wheel is connected with the wind tower with rotor shaft 12 equijoin parts by wind wheel bearing 10.Wind wheel dish 9 is made up of three rings, and outer shroud and interior ring are in order to fixing fan blade, and there is initiatively couple of force ring 11 centre, and initiatively the effect of couple of force ring is that the mechanical force that wind wheel rotates is passed to permanent magnet generator by driven couple of force.

Working principle: be wind wheel dynamic figure at a time as shown in Figure 1, if wind is to blow to the drawing top by the drawing below, the blade 1 that then is positioned at the right is owing to the thrust of wind will be fallen on the down wind backward, together Xuan Zhuan BLADE FORCE arm rest is on brute spring, because brute spring is not yielding, so the reaction force that blade 1 is subjected to is very big, fall its just slight back.Only it just can be significantly back to avoid self damage under very strong wind-force.Meanwhile, when the wind-force of equidirectional acted on the blade on the left side, along with upwards falling of this fan blade backward, the blade arm of force together back fell, because the weak spring easy deformation is very little to the reaction force of fan blade, so fan blade will fall down significantly; Because the blade of front and back position is the side wind-engaging, they can not fall down, and the power behind their wind-engagings acts on the rotor shaft, and they do not have any effect to the rotation of wind wheel.As can be seen, so long as be in the blade on rotor shaft the right, owing to it does not fall the back, therefore just to accept wind-force than large size; And be in the blade on the rotor shaft left side, because it fall down, so accept wind-force hardly.Like this, wind wheel will be to rotation counterclockwise under the effect of wind-force, and wind energy just is converted to mechanical energy.If the installation direction of all brute springs and weak spring is exchanged, then the sense of rotation of wind wheel will be exchanged.Can make more than three or three or several fan blades on the wind wheel.

Embodiment 1:

Fig. 2 and shown in Figure 3 be a kind of fan blade schematic representation of installed thrust formula spring, blade can be by iron among the figure, various metals such as aluminium and alloy thereof, various nonmetal manufacturings such as perhaps wooden, plastics, glass fibre reinforced plastics, carbon fiber; Weak spring and brute spring are plate-shaped springs, saucerspring or the nonmetallic rubber with metal, and plastics and synthetic fiber or the like are made.Fan blade spiral arm 7 is supporters of fan blade, by it blade structure is fixed on the wind wheel dish.Two kinds of wind-engaging working conditions of the blade arm of force are shown respectively among Fig. 4,5, and promptly the state that wind-force and reverse side are not accepted wind-force is accepted in the fan blade front.

As Fig. 4, when wind-force blowed to a left side by the right side, the blade 1 and the blade arm of force 4 were to the figure anticlockwise, and the blade arm of force produces a thrust to brute spring, because brute spring is not yielding, so fall the just slight back of fan blade.As Fig. 5, when wind-force blows to the right side by a left side, be equivalent to it and rotated 180 situations when spending with the rotation of wind wheel, the blade and the blade arm of force rotate to the right, and weak spring is produced thrust, because the weak spring easy deformation, so blade falls down.

In Figure 30, permanent magnet 22 is vertical permanent magnet, that is: the vertical permanent magnet of saucerspring.The quantity of its permanent magnet can be one, or a plurality of to 50; Pole coil 23 can be with one or more to 50.Be with three vertical permanent magnets and a coil among the figure.

Figure 31 also is a plurality of horizontal permanent magnet 22 structures, that is: a plurality of horizontal permanent magnet with saucerspring is single or multiple pole coil work, and its permanent magnet quantity can be one, and is a plurality of to 50; Pole coil can be with one or more to 50.Among the figure three horizontal permanent magnets, three coils.

Vertical or the horizontal single magnet of one-tenth according to circumstances capable of being combined and single pole coil, magnet and many pole coils

The utility model adopts vertical axis rotor, and its advantage has: one, because rotor shaft is perpendicular to ground, wind wheel is to rotate in the horizontal direction, and its occupied area is aerial area, so do not influence ground any facility and scenery; Two, fan blade does not exist and moves up and down, and the wind tower can be fixed with cable wire, thereby the wind tower do not bear the horizontal thrust of resisting wind, so its robustness is not had too high requirement, volume size can be done very for a short time; Three, because the wind-receiving face of wind wheel is on same wind-force aspect, do not have stressed irregular problem, rotor shaft is stressed less and even, therefore needn't do very big very solidly.

Two) adopt elasticity speed change rare earth permanent-magnetic generator, its advantage has: one, and the rare earth permanent magnet volume is little, and is in light weight, and magnetism intensity is big.Two, the generator magnetic pole number is few, and the coil total number of turns is few, and is simple in structure.

Because wind-driven generator is subjected to the uneven influence of wind-force size, output power stably often.Make power supply reliable and stable, should adopt many typhoons power generator and become network power supply, or insert the work of large-scale power net.Therefore, well behaved combining inverter is indispensable, and it is the basic components of back-up system proper functioning.It can be according to the size of wind energy, and line voltage just inserts or withdraws from electrical network or increase automatically and reduces to export electric energy, makes it to reach transient equiliblium.Inserting big network operation is a kind of desirable method, and this is because wind-force is a kind of extremely unsettled natural energy resources, in time, all is skewness on the space and on the region.Though can with bigger wind power plant spatially obtain metastable wind energy on the region, because wind-force with changes of seasons, can not obtain desirable compensation, only can compensate in time with huge electric power system.The utility model adopts the work of electronics automatic synchronization combining inverter.

As Figure 32 and Figure 33 is electronics automatic synchronization combining inverter electrical schematic diagram, and these two kinds of circuit all have following function: (1) changes the direct current energy of storage battery into circuit voltage, cycle, and the AC energy that phase place is identical, and be sent to circuit.(2), regulate the output power size automatically by retaining ground according to the level of charge of wind-driven generator to storage battery.(3) according to the size of line voltage distribution, regulate the output power size automatically by retaining ground.(4) when the circuit no-voltage maybe needs to work independently, self-excitation produces 50 hz AC excitation pulses, and inverter is worked alone.Figure 34 is the External view of these two kinds of inverters.

As Figure 32 is a linear circuit electronic inverter schematic diagram, working principle:

(1) JX1 and the JX2 positive-negative output end after the power generator rectification of giving a dinner for a visitor from afar respectively, voltmeter CB can indicate the charge condition of storage batteries D C.When battery DC terminal voltage reaches minimum permission operating voltage, voltage-stabiliser tube D1 conducting, electric current is lighted the D2 luminotron tube through R1, shows that battery has possessed power supply capacity.

(2) cell voltage is through D3, and R3 charges to C1, and when the forward voltage drop that is charged to greater than D4, IC1 output high level makes the BG1 conducting, makes terminal E2 place obtain a power supply voltage after the delay, and this voltage passes through R7 and lights luminotron tube D5 simultaneously, shows that inverter can work.

(3) E2 voltage one tunnel by the R10 step-down, is added to by R11 after the D6 voltage stabilizing then through R9, R12, and R13, R14, the stepped-up voltage that R15 forms forms the loop, and stepped-up voltage is added to the negative input end of voltage comparator ic 2～IC6 respectively.

(4) E2 voltage adds to whole positive input terminals of above-mentioned voltage comparator also through the bleeder circuit of R8 and R16 composition after the dividing potential drop.

(5) when the voltage of E2 end progressively is recharged increase with battery, voltage comparator ic 2～IC6 will one by one export high level, and order is IC6 output earlier, exports behind the IC2.

(6) the high level branch of above IC2～IC6 output is lighted D7～D11 and to relay J 1～J5 power supply its corresponding contact J1-1～J5-1 is connected, access and the disconnection of controlling resistance R17～R21 respectively.

(7) the outside line alternating voltage is introduced by JX3 and JX4, and the interchange output electric energy of inverter is also sent thus, and when K switch 1 was swung to the left side, line voltage distribution JX3 was through K1, R17～R21 one of them or several to transformer B1, return the other end JX4 and form the loop.

(8) transformer B1 carries out line voltage distribution step-down and isolates the back by R24, and R25 to the base drive of inverter power to pipe BG4 and BG5, is boosted by the B2 transformer after amplifying, by JX3 and the anti-circuit of delivering to of JX4 respectively.

(9) when IC2～IC6 all exports high level, because R17～R21 connects by relay entirely, to make line voltage distribution be added to B1 elementary the biglyyest, thereby secondary inverter power is made maximum excitation to pipe BG4 and BG5, so inverter is operated in peak output.On the contrary, as when having only IC6 output high level, inverter then is operated in minimum power.

(10) transformer B3 is a Monitoring Line voltage, when in case line voltage distribution is too high, the B3 secondary voltage is through D16, D17, D18 adds to the stepped-up voltage loop of voltage comparator ic 2～IC6 behind the voltage breakdown voltage-stabiliser tube D20 after the D19 rectification, i.e. the T end, the line electricity voltage rise is got when higher, reduce the inverter output power.

(11) R27, R28, D14, R29, D15 are the temperature that detects inverter power tube, when inverter power is big to the pipe heating, the voltage that the voltage divider of being made up of R27 thermistor and R28 produces is higher than the D14 breakdown voltage, just send a signal and give the stepped-up voltage loop of IC2～IC6, promptly T holds, to reduce inverter power.

(12) by BG6, R33, R34, R35, R36, R37, C4, C5, C6 forms a low frequency, as 50 hertz of left and right sides sinusoidal signal generators.By BG7, R38, R39, R40, C7, the power amplifier that B4 forms amplifies, when the circuit no-voltage or when needing inverter to work independently, K switch 1 and K2 are all swung to the right side, and sinusoidal signal generator and power amplifier are started working, and energizing voltage of the same output of transformer B1 works alone inverter.

(13) R6, BG2, BG3 and D2 are monitoring inverter working conditions, when inverter works in busy hour, IC2 exports high level, this level through R6 to composite pipe BG2 and BG3, therefore signaling lamp ZD is lighted, because ZD power is bigger, and it is installed on the inverter shell, so the manager also can judge probably whether generator and inverter work by the whether luminous of ZD a long way off.

Voltage comparator ic 2～IC6 can be by LM124 among Figure 32, LM224, and LM324 or the like operational amplifier, or LM119, LM139, LM160 or the like voltage comparator is formed, and its quantity is 3 to 50.Relay J～J5 can use compositions such as dry reed relay, mercury-wetted relay, common relay, and quantity is 3 to 50.Inverter power is to pipe BG4, and BG5 can be composed in parallel by two to 20 power tubes.Sinusoidal signal generator can be by the wien oscillator circuit, and the LC vibrator circuit is formed.Power amplifier BG7 can be single power transistor work, perhaps is connected into push-pull mode work by two or four power transistors.

Figure 33 does following change on the basis of Figure 32: (1) inverter is used switching circuit work instead; (2) relay J 1～J5 uses simulation of integrated circuit switch I C14～IC18 instead.Advantages such as after so changing, it has the power supply conversion efficiency height, and is in light weight, and the life-span is long.

Working principle:

(1) E1, E2 are connected on the E1 among Figure 32 respectively, the position of E2, and promptly power supply the principle is identical.

(2) E2 voltage forms when storage battery is charged to the minimum operating voltage of inverter, E2 produces a burning voltage through R20 on D13 then, form the last generation of circuit R22～R26 stepped-up voltage through R21 for past stepped-up voltage again, add to the negative input end of voltage comparator ic 9～IC13 then respectively.E2 voltage supplies the whole positive input terminals toward comparator IC9～IC13 after R19 and R27 dividing potential drop simultaneously.When E2 voltage continued to raise, voltage comparator was exported high level one by one, and order is that the output IC9 of IC3 elder generation exports at last.

(3) high level of above-mentioned IC9～IC13 output is lighted D14～D18 respectively and is made junction closure among simulation of integrated circuit switch I C14～IC18, finally makes R33～R37 be connected in parallel on R9 respectively and goes up to change the effective resistance of R9.

(4) the outside line alternating voltage is introduced by JX3 and JX4, and it is elementary to insert transformer B5 through K switch 2, and next level is exported the waveform of positive-negative half-cycle respectively and delivered to voltage comparator ic 3, IC4 and IC7, the positive input terminal of IC8 through D19 and D20 respectively.The output electric energy of this inverter also is to be sent by JX3 and these two terminals of JX4.

(5) high frequency pulse generator of being made up of the IC19 that includes frequency divider is sent high-frequency pulse signal, sends into through R40 and is exported by emitter-base bandgap grading after amplifier BG7 amplifies, and is sent to IC1 more respectively, IC2 and IC5, the input end of four AND circuits of IC6.

(6) at the positive half cycle of outside line voltage, B5 level of transformer is output as negative just down, the upper end positive voltage makes IC3, IC4 exports high level, and their negative input end is a low level all, makes IC1, two of IC2 and door are opened, high-frequency impulse is supplied with BG1 and BG2 respectively, and wherein BG1 isolates and D1 with the pulse amplification and through transformer B1, offers the conducting trigger current of controllable silicon SCR 1 after the D2 rectification.BG2 then is an inverter, and it changes direct current energy into high-frequency electrical energy, and through D3, D4, D5, after the D6 rectification, a route controllable silicon SCR 1 is to circuit output, and another road is conducted to photo coupler GD1 and exports a voltage to R9 through R3.When the voltage on the R9 was gone up terminal voltage above B5 level, the IC3 output low level was closed IC2, and inverter quits work.Reduce to when being lower than B5 level and going up terminal voltage when the voltage on the R9, IC2 exports high level again, and inverter is started working again.So repeatedly the working clearance of control inverter, make the voltage of inverter output follow the variation of B5 secondary voltage all the time, and follow the variation of line voltage distribution indirectly, finished the inversion output of positive half cycle.

(7) at the negative half period of outside line voltage, B5 level of transformer is for just bearing down, and following terminal voltage makes IC7, and IC8 exports high level, makes IC5, and two of IC6 and door are opened, the same upper half of its working principle, and what just it was finished is the inversion output of outside line voltage negative half cycle.

(8) when battery tension continues to raise owing to the increase of charge strength, R33～R37 one by one is access in and is parallel on the R9, make the voltage on the R9 become comparatively slow with the reaction that the increase of inverter output voltage increases, therefore inverter output voltage want corresponding increase that R9 is gone up to obtain identical output voltage so that IC3 or IC7 output low level to close inverter, therefore, the resistance of change R9 has just been realized effective adjusting of output power.

(9) be applicable to this circuit to the outside line overtension with to the circuit of the too high protection of inverter operating temperature among Figure 32, its control voltage is also introduced by T.

(10) when circuit no-voltage or inverter worked independently, K switch 1 and K2 swung to the left side, by BG5, BG6, R11, R12, R13, R14, R15, R16, R17, R18, C1～4,50 Hertz oscillation and amplifier that B6 or the like forms are started working, and transformer B5 works alone inverter under the promotion of this signal.

Voltage comparator ic 9～IC13 can be by LM124 among the figure, LM224, and LM324, LM106, LM160, LM161 or the like operational amplifier, or LM119, LM139, LM160 or the like voltage comparator is formed, and its quantity is 3 to 50.Simulation of integrated circuit switch I C14～IC18 can be by CD4016, CD4066, and CD4551 or the like forms, and its quantity is 3 to 50.High frequency pulse generator can be by CD4045, and CD4060 or the like vibration and frequency divider are formed.IC1, IC2, IC5, IC6 can be by CD4011, CD4012, CD4023, CD4073, CD4081, CD4082 or the like forms with door and AND NOT gate.

By on can find out, generator of the present utility model is by comparison circuit exclusive disjunction amplifier control inverter output power, by outside line, be that the line voltage cycle makes it to produce the inverter that identical voltage week involves the output electric energy of phase place with the phase lock inverter, comprising the inverter circuit of linear circuit or switching circuit composition; The 50Hz low frequency signal that produces with inverter self replaces line voltage distribution to finish voltage cycle and the standard compliant power output of phase place; And utilize photo coupler and gate circuit control switch circuit and one-way SCR that dc inversion is 50Hz or 60Hz AC energy.
