Abstract
The utility model relates to an internal-combustion engine starting protector comprising an hydro cylinder provided with a insulating board which is provided with the two electrical contacts, the extending end of the hydro cylinder shaft is provided with the electrical connecting sheet which can control the on-off of the two electrical contacts, the two electrical contacts and the electrical connecting piece form the oil switch controlled by the hydro cylinder, the oil switch and the relay normally open contact controlling the starting engine show the series, the sucker of the hydro cylinder is connected with the oil pressure hole of the internal-combustion engine to be supported the oil by the internal-combustion engine. The utility model has the advantages that when the internal-combustion engine is working, the oil switch in the off state; and when the key switch or the relay splicing is on, the starting engine is cold, the long time energizing can be avoided, the stating engine can be effectively protected.
Description
Technical field
The utility model relates to a kind of internal combustion engine start protector.
Background technique
By oil engined locomotive, usually being prone to the malfunctioning or circuit relay of key operation as automobile, excavator, loader, road roller etc. burns out bonding, the Starter circuit can not be disconnected be in the state that long-term energising moves, because Starter generally just easily burns after 10-15 minute in lasting energising running, therefore the Starter turnover rate of internal-combustion engine is very high at present, burning of Starter caused short circuit simultaneously, storage battery is easy to produce blast, very dangerous, be present problem demanding prompt solution the working life of therefore how to improve Starter.
The model utility content
The utlity model has an oil cylinder, end at cylinder block is provided with insulation board, insulation board is provided with two electrical contacts, the piston rod external part of oil cylinder is provided with the electric connecting sheet that described two electrical contacts are switched on or switched off, two electrical contacts and electric connecting sheet form an oil control switch by oil cylinder control, this oil control switch is connected with the relay normally open contact of control Starter, and the oil cylinder oil inlet pipe is connected by the internal-combustion engine fuel feeding with the oil pressure hole of internal-combustion engine.
Be connected with a buzzer between above-mentioned oil control switch and the relay normally open contact.
The oil suction chamber of above-mentioned oil cylinder is connected with an oil pressure gauge.
Because the utility model has increased an oil control switch of connecting with relay normally open contact in existing Starter circuit; and this oil control switch is controlled by an oil cylinder; the filler opening of this oil cylinder is by the internal-combustion engine fuel feeding; as long as the oil pressure of internal-combustion engine illustrates that normally internal-combustion engine is in work; oil control switch on the oil cylinder is in off state; even and this moment key operation or relay is bonding can not disconnect; Starter can not switched on yet; avoid Starter because of the long-term energising of line fault, effectively protected Starter thus.
The utility model can also increase a warning function, when the oil pressure of internal-combustion engine is not enough, the utility model can reflect immediately, the one, show by the utility model oil pressure gauge, the 2nd, because of piston rod of the present utility model retreats, make oil control switch connection, just can report to the police when increasing a buzzer, prompting staff oil pressure is not enough.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
Embodiment
The utlity model has an oil cylinder 1 as can be seen from Figure 1, the oil of oil cylinder 1 is supplied with by internal-combustion engine, and the oil inlet pipe 7 of oil cylinder is connected with the oil pressure hole of the former installation oil pressure gauge of internal-combustion engine; One end of cylinder block 2 has an insulation board 3, affixed two electrical contacts 4 on this non-conductive plate 3, oil cylinder piston bar 5 is provided with electric connecting sheet 6, be used for the connection or the disconnection of above-mentioned two contacts, piston rod 5 is in the maximum functional position at low order end when the internal-combustion engine oil pressure is enough, this moment electric connecting sheet 6 and two contacts 4 from, when the internal-combustion engine oil pressure is not enough or when not having oil, piston rod 5 is return promptly at left end, this moment, electric connecting sheet 6 linked to each other with two electrical contacts 4, and in fact two electrical contacts 4 and electric connecting sheet 6 form an oil control K switch 2.
Oil control K switch 2 is connected with the relay normally open contact J1 of control Starter as can be seen from Figure 2; make only not enough or oil control K switch 2 conductings when not having oil of Starter M at the internal-combustion engine oil pressure; and Starter M just works under the situation that key operation K1 also opens; when I. C. engine oil presses when being raised to certain value; the utility model piston rod 5 moves to right, and oil control K switch 2 disconnects, and makes Starter M outage automatically; therefore motor is not worked under the normal situation of oil pressure, has protected Starter M thus effectively.
It can also be seen that from Fig. 1 the utility model is equipped with oil pressure gauge 8 to show the oil pressure situation in the internal-combustion engine at any time at an end of oil cylinder oil suction chamber.
And between described oil control K switch 2 and relay normally open contact, also connected a buzzer F in the circuit as can be seen from Figure 2, so that under internal-combustion engine has oil condition, do not report to the police.
