At present, the power of Low Power Gasoline Generator (output power is not more than 10kw usually) all adopts general small-size gasoline engine, for guaranteeing that generator is when changing with the electrical load size, all can send voltage, the frequency of stable and consistent, the rotating speed of petrol engine must be stabilized in 3000r/min (corresponding output voltage is 50HZ) or 3600r/min (corresponding output voltage is 60HZ), for reaching this purpose, currently used mode is and loads a mechanical type centrifugal fly-weight speed regulating mechanism on petrol engine.Along with the demand than high-power generator group (output power is greater than 15kw) is strengthened gradually, must select the power resources of more powerful petrol engine for use as generator set, for reducing cost, general all is the motor petrol motor of directly using on the existing market, and motor petrol motor and general small-size gasoline engine all have bigger difference on structure and profile, install mechanical type centrifugal fly-weight speed regulating mechanism thereon additional, because structure, the restriction of aspect, space, to make the whole generating set structure become very complicated, and often must change the housing structure of motor petrol motor, be unfavorable for the reduction of cost.
The model utility content
The purpose of this utility model provides a kind of direct employing motor petrol motor as power resources, the large power electric control gasoline engine generator group of output voltage stabilization and compact structure.
For this reason, large power electric control gasoline engine generator group described in the utility model comprises petrol engine and generator, and petrol engine is the motor petrol motor, and the flywheel of its output axle head links to each other with starting electrical machinery, and an end of flywheel links to each other with the rotor shaft of generator by connecting pawl; The carburetor throttle of motor petrol motor links to each other with stepper motor, and stepper motor is connected on the speed regulating control processing unit, and the speed regulating control processing unit links to each other with sensor, and sensor is located on motor petrol motor or the generator.
Preferably be provided with flywheel guard between above-mentioned generator and the motor petrol motor, starting electrical machinery is installed on the flywheel guard, the stator of generator is installed in flywheel guard by seam and generator supports on the tailstock, flywheel guard and generator support between the tailstock and socket together with bolt, on flywheel guard, the other end is supported on the tailstock at generator by bearings by bearings for one of the rotor shaft of generator.
Above-mentioned flywheel can be provided with land with being connected between the pawl, connects between pawl and the land to be provided with rubber pad, connects between the rotor shaft of pawl and generator to be connected with bolt by key.
The power source of generator set adopts the motor petrol motor in the utility model, with in the existing generator set the general gasoline engines that generally adopts compare, its output power is big, can directly use existing motor petrol motor, as minicar engine, thereby can reduce cost.The output terminal of motor petrol motor has flywheel and starting electrical machinery, can realize that the electricity of generator set starts.Sensor is used for the output voltage of inspection vehicle with petrolic rotating speed or generator, and should import in the speed regulating control processing unit by detected signal, by speed regulating control processing unit control step machine operation, and by the size of step motor control motor petrol engine and carburetor closure, thereby realize the stable of generator set output voltage.Because sensor, speed regulating control processing unit and stepper motor need occupation space all very little, are easy to just can be installed on motor petrol motor or the generator, make whole generating set structure compactness, it is little to take up room.
The beneficial effects of the utility model are: output power is big, and can realize regulating automatically making output voltage stabilization, compact structure, and it is little to take up room, and cost is low.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of output power is greater than the large power electric control gasoline engine generator group of 15kw, its petrol engine as power source is a motor petrol motor 2, the flywheel 3 of motor petrol motor 2 output axle heads links to each other with starting electrical machinery 4, and an end of flywheel 3 links to each other with the rotor shaft 6 of generator 1 by connecting pawl 5.The carburetor throttle 7 of motor petrol motor 2 links to each other with stepper motor 8, and stepper motor 8 is connected on the speed regulating control processing unit 9, and speed regulating control processing unit 9 links to each other with sensor 10.Sensor 10 can be a speed probe, be installed on the rotating part of motor petrol motor 2 (as flywheel 3, camshaft etc.), the instant tach signal of motor petrol motor 2 is in time fed back to speed regulating control processing unit 9, speed regulating control processing unit 9 is passed to control signal stepper motor 8 again, control the aperture size of motor petrol motor 2 carburetor throttles 7 by stepper motor 8, thereby make the output voltage of generator set keep stable.Sensor 10 also can be voltage transducer, is located at the output terminal of generator 1, controls, regulates the rotating speed of motor petrol motor 2 by the output voltage that detects generator set, and finally reach the purpose that makes generator set output voltage, frequency stabilization unanimity.
