Abstract
The utility model discloses an engine over temperature alarm which is composed of a temperature controlled switch, a relay, a sound buzzer, an ignition coil and a DC power supply. One end of the temperature controlled switch is connected to the cathode of the DC power supply, the other end is connected to one end of the relay coil, the other end of the relay coil is connected with one end of the power switch, and the other end of the power switch is connected with the anode of the DC power supply; the normal open contact of the relay is connected with one end of the ignition coil, the other end of the ignition coil is connected with the cathode of the DC power supply; the normal close contact of the relay is connected with the sound buzzer, and the other end of the sound buzzer is connected with the cathode of the DC power supply. The utility model has the advantages of simple manufacturing, convenient mounting, low cost and reliable working.
Description
Technical field:
The utility model relates to the too high alarm of motor temperature that a kind of Motor Vehicle uses.
Background technique:
Motor occurs causing engine temperature too high because of faults such as cooling system or radiation systems through regular meeting.If this problem can not be in time found in operator's carelessness, motor is remained in operation, will cause motor to damage, each parts wear and tear under high temperature condition all can be increased, and accelerated ageing can cause complete machine to scrap when serious.
The model utility content:
The purpose of this utility model is to overcome above-mentioned deficiency, and can in time report to the police when providing a kind of engine temperature too high, the alarm of And can put out automatically fire.
The utility model is that the technological scheme of being taked that achieves the above object is: a kind of motor overtemperature alarm, form by temperature detect switch (TDS), relay, voice buzzer, spark coil, DC electrical source, temperature detect switch (TDS) one end is connected with dc power cathode, the other end is connected with relay coil one end, the relay coil the other end is connected with power switch one end, and the power switch the other end is connected with dc power anode; Relay normally open contact is connected with spark coil one end, and the spark coil the other end is connected with dc power cathode; The relay normally closed interlock is connected with voice buzzer one end, and the voice buzzer the other end is connected with dc power cathode.
Temperature detect switch (TDS) is installed on the engine temperature induction plug.Temperature detect switch (TDS) is a normally closed switch.
The utility model compared with prior art has advantages such as making is simple, easy for installation, with low cost, reliable operation.
Description of drawings:
Fig. 1 is the utility model electrical block diagram.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of motor overtemperature alarm, form by temperature detect switch (TDS) 1, relay, voice buzzer 9, spark coil 8, DC electrical source 5, temperature detect switch (TDS) 1 one ends are connected with DC electrical source 5 negative poles, the other end is connected with relay coil 2 one ends, relay coil 2 the other ends are connected with power switch 4 one ends, and power switch 4 the other ends are connected with DC electrical source 5 positive poles; Relay normally open contact 6 is connected with spark coil 8 one ends, and spark coil 8 the other ends are connected with DC electrical source 5 negative poles; Relay normally closed interlock 7 is connected with voice buzzer 9 one ends, and voice buzzer 9 the other ends are connected with DC electrical source 5 negative poles.Be parallel with a diode 3 at relay coil 2 two ends.
Temperature detect switch (TDS) 1 is installed on the engine temperature induction plug, and temperature detect switch (TDS) 1 is a normally closed switch.
When turning on the power switch 4, relay coil 2 energisings, its normally open contact 6 closures of adhesive, spark coil 8 gets electric work, and ato unit runs well; When engine temperature reaches 110 when spending, temperature detect switch (TDS) 1 automatic disconnection, relay coil 2 power down, its normally open contact 6 disconnects, and spark coil 8 power down make the motor auto extinguishing; Relay normally closed interlock 7 closures, voice buzzer 9 gets electric work and reports to the police.
