Abstract
An automatic water discharging device of an engine includes a thermistor, a resistor, a capacitor, a diode, a triode, a relay, an integrated circuit, a potentiometer and an electromagnetic valve, wherein the model of the integrated circuit is NE555; and the thermistor is a resistor with positive temperature coefficient. Compared with the prior art, the utility model has the advantages that the automatic water discharging device of the engine has simple structure and low cost, is convenient to mount and use, and can effectively prevent the engine from being cracked by freezing.
Description
Technical field
The utility model relates to engine cycles system optional feature, is specifically related to the automatic jettison gear of a kind of motor.
Background technique
At present; Existing motor adopts water cycle to force the type of cooling more; Therefore need to form the cooling water recirculation system of a sealing through water tank, water pump, engine cylinder-body etc.; Lower position in cooling water recirculation system also will be provided with a cock of water drain, is used to change when discharging water circulating water or cold season use.
In the winter time or the northern China cold zone, in order to prevent motor and water tank not by bursting by freezing, the antifreeze liquid of generally will in cooling water, annotating, but antifreeze liquid is more expensive, can increase user cost; Big multi-user (rural subscribers are in the majority) does not add antifreeze liquid for saving, but when ambient temperature reduces, the cooling water in motor and the water tank is bled off.Yet in use, the unavoidable existence meets change in weather, forgets and discharge water or forget the antifreeze liquid of in cooling water, annotating, and causes motor to suffer unnecessary loss because of bursting by freezing.
The model utility content
The purpose of the utility model is exactly the defective that exists to existing technology, provides a kind of motor automatic jettison gear.
Its technological scheme is: comprise thermistor, resistance, electric capacity, diode, triode, relay, intergrated circuit, potentiometer and solenoid valve.Power end is connected with an end of thermistor, an end of first relay and an end of first relay contact; The other end of thermistor is connected with the base stage of first triode and an end of first resistance; The other end of first relay is connected with the collector electrode of first triode; The other end of first relay contact is connected with a fixed end of potentiometer, the moved end of potentiometer, 4,8 pin of intergrated circuit, an end of second relay and an end of second relay contact respectively; Another fixed end of potentiometer is connected with an end of second resistance; The other end of second resistance is connected with 2,6 pin of intergrated circuit and the positive pole of first electric capacity, and 5 pin of intergrated circuit are connected with an end of second electric capacity, and 3 pin of intergrated circuit are connected with the base stage of second triode; The other end of second relay is connected with the collector electrode of second triode, and the other end of second relay contact is connected with an end of solenoid valve; The other end of 1 pin of the other end of the negative pole of the emitter of the other end of first resistance, first triode, first electric capacity, second electric capacity, intergrated circuit, the emitter of second triode and solenoid valve connects the back grounding end; The said first relay two ends also are parallel with first diode, and the said second relay two ends also are parallel with second diode.
Wherein, said intergrated circuit model is NE555.Said thermistor is a positive temperature coefficient resistor.
The utility model compared with prior art, have simple in structure, easy to install, with low cost, can prevent effectively that motor is by the advantage of bursting by freezing.
