Description
Technical field
The utility model relates to a kind of control circuit of vehicle extinguishing device.
Background technology
More and more universal along with automobile, also more and more receive people's concern to the safety guarantee of automobile; Automobile is in long-time driving process, easily because continue the accumulation of heat, cause short circuit or some device fire that causes on fire in automobile, perhaps because automobile travels in hot environment, easily spontaneous combustion, in prior art, there is no effective method and device with fire extinguishing, in view of this, be necessary to design that a kind of cost is low, easy to implement, the vehicle extinguishing device of good reliability, and control circuit is the core of vehicle extinguishing device.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of control circuit of vehicle extinguishing device, and the control circuit of this vehicle extinguishing device is simple in structure, easy to implement, be swift in response.
The technical solution of utility model is as follows:
A kind of control circuit of vehicle extinguishing device, comprise power supply circuits, branch road and temperature control branch road detonate; Power supply circuits, detonate branch road and all parallel connections of temperature control branch road;
In power supply circuits, two termination car direct current power supplies of the coil of relay J 1; The central contact of relay J 1 is as the positive output end of power supply circuits; Another output of power supply circuits is ground; The normally opened contact of relay J 1 connects the anode of car direct current power supply; The normally-closed contact of relay J 1 connects the anode of automobile standby battery; Automobile standby battery and car direct current power supply are altogether;
The route temperature sensing cable of detonating is in series with igniter, and igniter is used for triggering fire extinguisher;
The coil that route temperature detect switch (TDS) and relay J 2 are propped up in temperature control is in series; The normally closed switch K2 of relay J 2 correspondences is serially connected in oil supply circuit.
When relay J 2 normally closed switch disconnect, oil supply circuit opens circuit, and fuel cut-off is removed hidden danger, the protection automotive safety.
Temperature detect switch (TDS) claims again the temperature-sensitive feedback device; Igniter claims again initiator.
Beneficial effect:
The control circuit of vehicle extinguishing device of the present utility model, control electrical source exchange by relay J 1, make fire extinguisher adopt the car direct current power supply power supply when normal operation, adopt the reserve battery power supply during car direct current power supply fault, thereby there is high reliability in power supply;
In addition, respond to the temperature at Automobile case lid place by temperature sensing cable, when temperature reaches predetermined temperature, (when on fire), ignite fire extinguisher by igniter, in time to stamp out the flames in time.
Further, by the break-make of relay J 2 and temperature detect switch (TDS) oil circuit control, when temperature sharply raises, when (while occurring as fire), cut off in time oil circuit, in the mode of taking away the firewood under the cauldron, avoid fire incident to spread, further ensured the fire extinguishing effect.
In sum, the control circuit reliability of this vehicle extinguishing device is high, the fire extinguishing effect that is conducive to obtain, and cost is low, is easy to promotion and implementation.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of control circuit of the vehicle extinguishing device of utility model.
The specific embodiment
Below with reference to the drawings and specific embodiments, the utility model is described in further details:
Embodiment 1:
As shown in Figure 1, comprise power supply circuits, branch road and temperature control branch road detonate; Power supply circuits, detonate branch road and all parallel connections of temperature control branch road;
In power supply circuits, two termination car direct current power supplies of the coil of relay J 1; The central contact of relay J 1 is as the positive output end of power supply circuits; Another output of power supply circuits is ground; The normally opened contact of relay J 1 connects the anode of car direct current power supply; The normally-closed contact of relay J 1 connects the anode of automobile standby battery; Automobile standby battery and car direct current power supply are altogether;
The route temperature sensing cable of detonating is in series with igniter, and igniter is used for triggering fire extinguisher;
The coil that route temperature detect switch (TDS) and relay J 2 are propped up in temperature control is in series; The normally closed switch K2 of relay J 2 correspondences is serially connected in oil supply circuit.
When relay J 2 normally closed switch disconnect, oil supply circuit opens circuit, and fuel cut-off is removed hidden danger, the protection automotive safety.
Described temperature detect switch (TDS) is arranged in the sidewall of fire extinguisher container.
The course of work of control circuit:
Carry out electrical source exchange by relay J 1 switching; When car direct current power supply has electricity, the normally opened contact of relay J 1 and intermediate contact conducting, be branch road and the power supply of temperature control branch road of detonating by car direct current power supply; Car direct current power supply is during without electricity, and the normally-closed contact of relay J 1 and intermediate contact conducting, be detonate branch road and the power supply of temperature control branch road by automobile standby battery;
Start fire extinguisher by the branch road that detonates with temperature sensing cable and igniter, temperature sensing cable is short circuit after being heated, and igniter detonates, the spray fire extinguishing agent fire extinguishing;
By relay J 2 with the break-make of the temperature control branch road oil circuit control of temperature detect switch (TDS); When temperature is elevated to 85 while spending, the temperature detect switch (TDS) conducting, the coil electricity of relay J 2, the normally closed switch K2 of relay J 2 disconnects, and cuts off automobile fuel feeding path.
The effect of electric detonator is point quick-fried (startup) extinguishing medium, makes medicament start to eject;
Temperature-sensitive feedback device (also being called temperature detect switch (TDS)) belongs to off-state at ordinary times, the resistance infinity, and when temperature is elevated to 85 while spending, thermistor is considered as short circuit, makes the coil electricity of relay J 2;
Temperature sensing cable is for temperature sensor, and when external temperature moment raises and reaches the startup value, horse back starts electric detonator and spraying medicine.
