Engine assembly E appearance is coated with wind scooper 20 on the cylinder body, bottom surface wind scooper 8, cylinder head wind scooper 9,14 4 coolings of side wind scooper fan housing, four are cooled off the cooling duct that forms motor between fan housing, spiral case 40 and baffler wind scooper 26 and the motor appearance, gap between spiral case 40 and the hand starting arrangement is the intake grill in air channel, be the air-out air channel between baffler outer cover and the baffler assembly 6, be equipped with the intake grill 18 of cooling air in the corresponding positions of shell hand starting arrangement; At outer casing back baffler cover plate 5 is housed, the exhaust outlet of cooling duct is arranged on the baffler cover plate 5, the sectional area of intake grill is less than the sectional area of exhaust outlet, thereby better motor cooled off.
Shown in Fig. 2 A, 4, hand starting arrangement has stay cord handle 15, stay cord and serving dish, and stay cord is wound on the dish, and fixedly connected with handle in the stay cord end, and stay cord handle 15 is arranged on the side of shell.
As Fig. 1, shown in the 2B, stamping part fuel tank 3 be installed in engine assembly E and frequency variator 11 above, support by the stamping part support of installing on the stamping part support installed between spiral case 40 and the hand starting arrangement and the body, make between fuel tank and the motor and form rigid joint, after fusing, motor and fuel tank be installed on the motor base plate 7, minimizing when motor moves owing to the difference of vibration frequency between motor and the fuel tank is damaged fuel tank, the shape of fuel tank 3 and the shape of shell are complementary, to utilize the space in the shell as far as possible is prerequisite, reach at fuel tank under the situation of a constant volume, digital electricity generating group machine volume is reduced; The top of fuel tank is provided with oil filler and fuel door 36, and the bottom is provided with oil outlet, is provided with oil spilling dish 33 between fuel tank and shell, in case can flow to the generator set outside when too much fuel oil overflows in refueling process rapidly.
As shown in figure 13, the oil outlet of the fuel from fuel tank of motor comes out, arrive 56 li of fuel filters through transport pipe 59, be connected on the fuel tank switch 58 by transport pipe 60 by fuel filter again, fuel tank switch 58 is linked on the oil transfer pump 19 through transport pipe 57 again, to Carburetor, wherein the power of oil transfer pump 19 is produced by the negative pressure that forms in the engine crankcase oil transfer pump through transport pipe 61.
Shown in Fig. 2 B, because portable digital generator set of the present invention is to be applied to field work, need rainproof, dustproof, therefore in the present invention, the front end of portable digital generator set is equipped with control panel 55, and rainproof, a dustproof transparent casing has been installed in control panel 55 fronts, and promptly rain cover 13, it can prevent effectively that rainwater and dust from entering control panel 55 inside, thereby has avoided the generation of some security incidents.Simultaneously, it is more beautiful in appearance that rain cover 13 also makes portable digital generator set of the present invention.
The electrical apparatus element of outside output are housed on the control panel 55, after frequency variator 11 is arranged at control panel 55, frequency variator has main circuit and control circuit, main circuit has switching circuit and output filter circuit, switching circuit has four insulated gate bipolar transistor IGBTs, control circuit has digital signal processor DSP, detect the output signal transformer of frequency converter output voltage, detect the output current transformer of frequency variator output current and the drive circuit of insulated gate bipolar transistor IGBT, drive circuit has four optical couplers, optical coupler is selected the optical coupler with short trouble measuring ability for use, the power supply of control circuit is provided through rectifying and voltage-stabilizing by the low-voltage alternating current power supply input, the output signal transformer is connected with the input end of digital signal processor DSP respectively with output current transformer, the optical coupler input end is connected with the digital signal processor DSP output terminal, and the output terminal of optical coupler is connected with insulated gate bipolar transistor IGBT.Output current transformer feeds back to digital signal processor DSP with output current signal and is used for overcurrent protection control; the output signal transformer is given digital signal processor DSP with the frequency converter output voltage signal feed back; digital signal processor DSP carries out frequency converter output voltage signal and given voltage the high speed comparison operation, obtains opening the turn-off time of insulated gate bipolar transistor IGBT with the space vector of voltage algorithm, adopts saddle type ripple pulse width modulation controlled mode SVPWM to remove to control the output voltage of frequency variator.
Shown in Fig. 4,5,10,11, spiral case 40, generator G, engine assembly E, fuel tank 3, frequency variator 11 and hand starting arrangement are housed in the shell, generator G is mounted in the volute 40 of motor, the stator 42 of generator is fixed on the body, and rotor 62 is mounted on the bent axle 43 of engine assembly E; The rotor of generator also plays a part flywheel simultaneously.During engine assembly E work, the rotor of generator is done cutting magnetic field with bent axle 43 rotations of engine assembly E and is generated electricity.
As shown in figs. 1 and 10, Fig. 1 and Figure 10 illustrate the engine arrangement structure of portable digital generator set of the present invention respectively.Can find out by Figure 10, the motor of portable digital generator set of the present invention is to adopt tilt cylinders to arrange, the centerline of the bent axle 43 of its engine assembly E is in level, and its below is the machine oil oil sump 21 of motor, and the left side is to have the motor chamber cap 2 of storing engine motor oil.
In existing, the digital frequency conversion generator group that is lower than 2KW in the market, all adopted the petrol engine of layout in upright arrangement, and the petrol engine that the claimant has adopted tilt cylinders to arrange, this caused the whole generating unit in profile with constructional different, thereby make the whole generating unit in height be significantly less than the market existing procucts, bigger on width, help utilizing arcuate handle 1 to drag the whole generating unit and move ahead, had certain novelty.
The motor chamber cap 2 of portable digital generator set of the present invention also has the effect that stores machine oil when petrol engine takes place to motor chamber cap 2 lopsidedness or topples over except that the traditional role with regular price gasoline machine gear chamber cover,
When the portable digital generator set moves or carries; motor usually can run-off the straight or overturning situation; this moment, the machine oil of engine sump tank 21 can be along the engine inner wall oblique flow; in the flow direction engine chamber cap 2; owing to be provided with the chamber that several store engine motor oil on the motor chamber cap 2 of the present invention; and each chamber has certain depth, is enough to store all engine motor oils.This moment, engine motor oil maximum oil face can not coincide with the cylinder sleeve zone, in the most of inflow engine chamber cap of machine oil in the oil sump 21 2 inner chambers, thereby satisfy depositing, moving or the carrying requirement to the portable digital generator set, prevent also that simultaneously machine oil from flowing in the cylinder sleeve zone, produces the phenomenon of burn oil when having avoided motor to work once more.
