In the present embodiment, throttle automatically control is to be transformed into the rectilinear motion of nut with wired hose (bicycle wire brake) by the circle of screw mandrel, drives spindle and post switch, realize that the size of throttle is controlled, thereby realization is to the control of generator machine output voltage.On the adjusting line of engine throttle or bar, steel wire casing and wire-core are housed.One of sleeve pipe is fixed on the carburetor, the other end is fixed on the actuating motor parts, one of wire-core fixes with regulating line or bar, and the other end is connected with the travelling nut that leads, guiding travelling nut spinning is on screw rod, and screw rod is connected or connects by clutch with the output shaft of deceleration reversible electric machine.When the generating set output voltage changes, electronic control circuit control becomes positive and negative the rotatablely moving of motor into the rectilinear motion of spigot nut, reach opening greatly or turning down of throttle adjustment bar or line by direct-connected wire-core, realize the effect of automatic voltage regulation.
The automatic stable pressure course of present embodiment generating set is, obtain sample voltage from the generating set output, and this sampling voltage and reference voltage compared, computing, logic determines, produce control signal control immediately and can reverse turning to and rotating speed of actuating motor, the gear of fixing on fixing gear and the screw rod on this reversible rotating motor output shaft is meshed, spigot nut and guide post connect as one and rotation set on screw rod, guide post is limited by keyway can only be along the screw rod length travel, under the effect of spigot nut, the circular motion of screw rod is converted to the rectilinear motion of guide post, guide post then is connected with an end of engine throttle adjusting steel wire, and the other end of this Throttle Opening Control steel wire connects the valve rod and the fuel-flow control spindle of engine and carburetor.For improving control precision and reliability, actuating motor is carried out three double speed controls, when the sampling voltage of generating set output departs from reference voltage when big, actuating motor runs up, when sampling voltage during near reference voltage, the motor low cruise has avoided oscillatory occurences to make control precision higher simultaneously.Furtherly, this throttle automatic control circuit has adopted the control mode of " three ", " two speed ", and promptly voltage is the control point by " upper limit ", " benchmark ", " lower limit " 3, and motor speed then is high speed low speed or many speed controls system.When occurring influencing the factor of generator output characteristic, fluctuation or skew can take place in the output voltage of generator, at this moment, feed back to control circuit and in time capture this variation, and the speed that generator output voltage is changed, direction, size changes control signal corresponding into, offer reversible rotating motor, reversible rotating motor is just made to be changeed, counter-rotating, at a high speed, low speed, the action that stops, and then drive advancing of guide post, move back, stop, reach the purpose of revising regulator generator output voltage size by instant adjusting engine oil mass size, this mode has realized the automated closed-loop control voltage stabilizing of voltage.Furtherly, when the output voltage variation reaches voltage " upper limit ", sampled signal and reference voltage compare, computing, logic determines, produce control signal immediately, control reversible actuating motor and turn to and rotating speed, the time away from reference voltage, motor is to run up, when near reference voltage, motor speed is reduced to low speed, when reaching reference voltage, motor then shuts down, when voltage is reduced to voltage " lower limit ", motor backward rotation, high speed rotating, during near reference voltage, motor speed is reduced to low speed, and when reaching reference voltage, motor shuts down.
Below in conjunction with physical circuit, further describe the process of motor positive and inverse control, self-sustaining and rotating interlocking.In the accompanying drawing 3, the IC7 benchmark is high-order C (240V), and when sampling voltage X was lower than reference voltage 240V, IC7 was output as 0, not conducting of BG13, and solid-state relay SSR1, SSR2 close, and actuating motor is not worked, and is just changeing this moment yet and is not working; X is higher than 240V when sampling voltage, and IC7 is output as 1, the BG13 conducting, and SSR1, SSR2 conducting, actuating motor counter-rotating (step-down), BG13 conducting simultaneously makes the BG16 conducting, and BG17 ends, and closing SSR3, SSR4 is that forward pins; Simultaneously after the conducting of BG13, through R28 with signal feedback to the IC7 anode, keep the high potential of IC7 anode, play holding function, promptly signal still keeps original operating state after removing, and makes actuating motor can keep reversing this moment; When sampling voltage dropped to 220V, the positive terminal potential of IC8 was higher than negative terminal, is output as 1, the BG14 conducting, and BG13 then ends, and actuating motor then stops operating.When sampling voltage X was lower than 220V, IC10 was output as 1, the BG17 conducting, and SSR3, SSR4 conducting, actuating motor just changes (boosting); The IC10 output is connected to the IC10 negative terminal by R33, BG15 simultaneously, makes the IC10 negative terminal keep electronegative potential, and the output state of IC10 can not change easily, thereby plays holding function; BG14 conducting simultaneously, BG13 ends, and SSR1, SSR2 are lockable.
In order to improve motor bridge-type control circuit, especially the security reliability of power switch pipe, ad hoc having counted by R1, C1, C2, D1, the double direction impulse absorption circuit in parallel that the D2 element is formed with work drive motor, be that H bridge direct current reversing motor absorbs circuit (referring to accompanying drawing 3), in the circuit, SSR is a solid-state relay, electrochemical capacitor C1, C2 and diode D1, D2 interconnects the composition ac capacitor, R1 is a current-limiting resistance, formed the oscillation due to discharge absorption circuit,, selected the parameter of corresponding absorption circuit according to the capacity of actuating motor, when actuating motor switch or commutation, can absorb impact fully, improve the reliability of circuit power tube.
In addition; present embodiment has also increased pressure limiting (speed) protective circuit (referring to accompanying drawing 3); an input of this protective circuit is connected to operating voltage protection value end; another input of this protective circuit is connected to generating set operating voltage sampling end, and the output of this protective circuit is connected to magneto high voltage package (GT).When sampling voltage is higher than upper voltage limit (engine speed surpass on the rotating speed of regulation in limited time), IC11 export high potential, connection magneto high voltage package (GT) W point and ground short circuit, and magneto quits work.
The generator output end of present embodiment connects digital frequency conversion circuit commonly used, as adopting the 7200MA series (referring to accompanying drawing 14) of east, Taiwan unit, make this generating set send stable midfrequent AC voltage, after digital electric controller frequency conversion inversion, promptly exportable single-phase, two-phase or three-phase sine-wave 50HZ alternating current.For realizing the stable voltage of generator output, adopted, present embodiment combines generator digital frequency conversion technology with distinctive throttle automated closed-loop control system, engine and generator are all operated under the high efficiency rotating speed, and the efficient with engine and generator can be fully played like this.By igniting, generating integrated design and through the digital electric control technology of world's latest development, realize high efficiency, the output of high-quality electric energy, reach that volume is little, in light weight, fuel saving.
The present embodiment generating set has adopted magneto, the shared rotor structure design of generator (referring to accompanying drawing 4,5).Be in the chamber of bowl-type magnetic conduction rotor 22 for generator partly, the outside of rotor be ignition system partly, promptly outer rotor generator and internal rotor magneto are common uses a rotor, save space, in light weight, cost is low, volume is little.
Magneto rotor is the internal rotor form, it requires magnet steel 23 according to certain technical parameter, magnetic inductive block 20 (magnet steel monolateral one or on the both sides of magnet steel each one), the location skeleton 24 of balance weight 27 and non-magnet material is assembled into one, promptly press fixedly magnet steel of certain specification requirement by non-magnet material location skeleton, magnetic inductive block, the position of balance weight, form a same thickness, same cylindrical and with the magneto rotor magnetic circuit alignment layers of rotor axial consistent size, (external diameter) covers on the both thin of a non-magnet material that cooperates with it outside the circumference of this alignment layers, the protective cover circle that intensity is good again, carrying out crimp on the both sides of cover circle axial dimension handles, both can prevent magnet steel, magnetic inductive block and balance weight come off because of centrifugal force, can avoid axial displacement again, can also increase the attractive in appearance reasonable of profile for product.
The inner face upper punch has several fan blades 25 in the axial inboard chamber of rotor, move towards specification requirement according to concrete wind path, the pressing direction of decision fan blade, producing air quantity when rotor rotates cools off generator amature and stator, having located a fan blade in the outside of rotor axial face (square with the axis face) is connected and the rotor disjunctor with screw with rotor, the same position at ramjet duct cooling fan blade place has breach on fan blade and rotor, for the generator cooling provides the air channel, when rotor rotates, engine is cooled off by engine wind-guiding case.Like this, the refrigerating function of generator and engine has been finished in the rotor rotation simultaneously.
It is an easily worn part of conventional electric generators that generator starts chest expander, and the reliability of chest expander dialing spring and eccentric tongue piece is inharmonious with operation.For solving this difficult problem; present embodiment has thoroughly changed traditional structure on structural design; and adopt high reliability, high-intensity scheme; and overcome because of understanding the powerful reverse resilience force that produces in the engine stopped process; for the four-stroke engine machine; the stroke of this resilience force can reach about 10 centimetres; cause the damage of chest expander through regular meeting; and the rope that present embodiment provides draw in the starter let out can extension spring and handle in buffer spring can well absorb above-mentioned resilience force, thereby guarantee that effectively rope draws starter not to be damaged.Detailed process is, when the starter-generator group, the operator at first overcomes buffer spring and the resistance of letting out the energy extension spring in the handle, make the block on the serving dish be close to the block on the dial and drive dial with the equidirectional rotation of serving dish, after dial rotates, shifting block on the dial is near centrifugal on the engine rotor Connection Block, and then the equidirectional rotation of drive rotor, after the smooth ignition start of engine, the rotating speed of engine improves, centrifugal torsion that under centrifugal action, overcomes the return torsion spring on the engine rotor Connection Block, outwards throw away, thereby break away from and the contacting of dial shifting block, at this moment, rope draws under the effect of starter buffer spring elastic force in letting out energy spring and handle, returns to poised state.When engine, stopping operating resilience force that moment occurs (direction of this resilience force is opposite with engine normal rotation direction), centrifugal of engine rotor Connection Block passes to dial with this reverse resilience force, make the dial backward rotation, at first to overcome the elastic force of letting out the energy spring in the backward rotation process of dial, (in this process, the part energy of the reverse resilience force of rotor is just let out can spring to be absorbed) dial is rotated further, block on the dial is near the block on the serving dish, and then drive serving dish is made backward rotation, the backward rotation of serving dish will inevitably produce a pulling force to unit inside to stay cord, and the part of this pulling force can be offset by the buffer spring in the handle, like this, engine stop reverse resilience force that moment producing just let out can spring and the handle buffer spring weaken for twice, consume, thereby effectively prevent of the harmful impact of this reverse resilience force stay cord and other parts.According to the difference of engine shutdown resilience force stroke, also can only adopt handle buffering stage clip or only adopt that let out in the dial can spring.
Embodiment two:
Throttle adjustment control device that present embodiment adopted and digital frequency conversion circuit and embodiment one are basic identical, are not repeated in this description at this.
The present embodiment difference is to have adopted another kind of generator unit structure form (referring to accompanying drawing 6), and this version is on existing put-put basis, and repacking a little increases generator and forms.This version does not change the internal structure of former engine substantially, just generator unit stator case 45 and engine cool wind scooper 31 are connected as a single entity by generator transition connecting plate 46, and the rotor of generator is fixed on the engine output shaft, simultaneously, also generator amature is provided with cooling fan blade, thereby effectively solves generator, the heat dissipation problem of engine.
