It also comprises alarm indicator lamp HL, and alarm indicator lamp HL and buzzer HA are in parallel.
Technique effect of the present utility model is: use it can automatically play decompression when single-cylinder engine starts, can prevent the Starter false tripping and can find in time that generator quits work, the key door that can also remind the driver to forget to close is got to 0, and is more secure and reliable to use.It is simple in structure, and is easy to use, is conducive to protection and maintenance to single-cylinder engine and circuit thereof.
Its main function is: 1, automatically control decompressor when starting; 2, when battery electric quantity is not enough, can cooperate startup with manpower; 3, after internal-combustion engine starts smoothly, can avoid the Starter false tripping; When 4, internal-combustion engine works, if the generating of generator cut can be reported to the police; If 5 artificially stop internal-combustion engine, and key door is not got back to 0, can report to the police.
Description of drawings
Fig. 1 is the utility model embodiment circuit theory and structural representation.
Embodiment
As shown in drawings; it also comprises housing, and buzzer HA, decompression starting auxiliary reclay KM1, startup time delay relay KM2, delay capacitor C, protective relay KM3, diode D1, D2, D3, D4, fuse protector FU, tractive magnet YE, manual cranking supplemental button SB and alarm indicator lamp HL are installed on the housing respectively.
1 of the positive pole of buzzer HA and internal-combustion engine key door links to each other; The positive pole of diode D1 links to each other with decompression starting auxiliary reclay KM1 coil and holds 2 with the internal-combustion engine key door to link to each other; The second end of fuse protector FU links to each other with the positive pole of internal-combustion engine storage battery; The second end that starts time delay relay KM2 normally opened contact links to each other with the first end of internal combustion engine start machine contactor KM coil, and the second end of the second end of internal combustion engine start machine contactor KM coil, the common port of decompression starting auxiliary reclay KM1 contact, protective relay KM3 normally-closed contact links to each other with the negative pole of internal-combustion engine storage battery respectively; The second end of protective relay KM3 coil links to each other with the neutral point of oil-electric engine G.The draw-bar of tractive magnet YE links to each other with the internal combustion engine start decompression lever and is used for starting decompression.
Working principle: key door is got to 1 first routinely before the starting apparatus combustion engine, 1 plugged of key door, buzzer HA and alarm indicator lamp HL alarm power connection can start.Key door is got to 2 subsequently, decompression starting auxiliary reclay KM1 coil and startup time delay relay KM2 coil get electronic work, the Chang Kaiduan of decompression starting auxiliary reclay KM1 contact and common port are closed, tractive magnet YE coil switch power, it involves and draws bar pulling internal-combustion engine decompression pull bar, internal combustion engine intake valve is opened realized decompression.The normally opened contact that starts simultaneously time delay relay KM2 is closed, and internal combustion engine start machine contactor KM coil gets electric, and the Starter plugged rotates, and drives I. C. engine crankshaft and rotates the realization internal combustion engine start; When reaching the rated speed startup, internal-combustion engine unclamps key door when finishing, key door resets to 1 from 2, decompression starting auxiliary reclay KM1 coil and startup time delay relay KM2 coil blackout stop action, the Chang Kaiduan of the decompression starting auxiliary reclay KM1 contact disconnection that resets, tractive magnet YE coil losing electricity reset internal-combustion engine decompression pull bar.Store at delay capacitor under the effect of electric weight, internal combustion engine start machine contactor KM coil is delay cut-off slightly, and Starter shutdowns of slightly delaying time guarantees that internal-combustion engine starts fully, the start-up course end.
The normal-closed end of decompression starting auxiliary reclay KM1 contact was closed after internal combustion engine start finished; oil-electric engine this moment normal power generation; its neutral point produces the voltage about 6V; make protective relay KM3 coil get electric; protective relay KM3 normally-closed contact is opened; buzzer HA and alarm indicator lamp HL dead electricity stop alarm, generator operation is normal.If in a single day generator stops generating in the internal combustion engine operation; the 6V left and right sides voltage that its neutral point produces becomes zero; protective relay KM3 coil losing electricity; protective relay KM3 normally-closed contact is closed; buzzer HA and alarm indicator lamp HL get electric alarm; the prompting generator operation is undesired, needs to be serviced.If find when starting that the storage battery electric weight is not enough, can't start with Starter, press manual cranking supplemental button SB and decompression handle in the time of can manual cranking, Starter can assistant starting, hand also can be more laborsaving.
Internal-combustion engine is normal start after, key door is got back to 1, starts time delay relay KM2 coil losing electricity, its normally opened contact disconnects, can guarantee internal combustion engine start machine contactor KM coil since can't plugged can false tripping.If the people is for stopping internal-combustion engine; and key door is not got back to 0; protective relay KM3 coil is the meeting dead electricity under the out-of-work effect of generator, and the normally-closed contact of protective relay KM3 resets buzzer HA and alarm indicator lamp HL plugged are reported to the police, and the prompting driver gets to 0 with key door.
