Abstract
The utility model relates to an alarming device of an engine water tank, in particular to a motor-vehicle water tank water-shortage alarm. The utility model has the technical proposal that the alarm consists of a water-level detection circuit, a power-supply circuit and an alarming indication circuit, which are connected with each other, wherein, the water-level detection circuit consists of a time base circuit IC, a resistor R1, a capacitor C2 and a water-level sensor CG, which are connected with each other; the power-supply circuit of the water-level detection circuit consists of a resistor R2, a capacitor C1 and a voltage regulator diode DW; the alarming indication circuit consists of a resistor R3, a triode T, an alarming indicator light DD and a rattle L. The utility model has simple structure and convenient assembly, and is sensitive and reliable, and has strong anti-interference capacity, and can instantly detect the water level and sound alarming before powering on the engine. Particularly for the large-sized vehicle with a rear-mounted engine, even the lead wire of the sensor is long and the contact resistance is large, the device can also reliably work.
Description
Technical field
The utility model relates to the warning device of engine water tank, specifically is a kind of automobile water tank boiler alarm.
Background technology
Motor car engine utilizes recirculated water to cool off, and the engine lack of water can be passed through water-thermometer, coolant temperature alert light indication generally speaking.But have in the actual use,, and have only that in use temperature is too high just can report to the police because water-thermometer and coolant temperature alert light coolant temperature alert light all are the temperature signal signals of gathering.The extraordinary operation of temperature of engine at this moment produces harmful effect to engine; Even find the too high warning of temperature, sometimes again can because of around lack the water source, and influence the engine operate as normal; Rear-engine coach particularly, reason such as long owing to circuit, that contact resistance is big often causes warning device not report to the police or false alarm, in the course of time, can make human pilot thought paralysis, so that cause damage.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of by detecting cistern water level, the automobile water tank boiler alarm that OnNow detects and reports to the police before startup.
Its technical scheme is: connected to form by water level detection circuit, feed circuit and warning indicating circuit three parts, wherein time base circuit IC, resistance R 1, capacitor C 2 and level sensor C G connect to form water level detection circuit; Connect to form the feed circuit of water level detection circuit by resistance R 2, capacitor C 1 and voltage stabilizing diode DW; Resistance R 3, triode T, alarm lamp DD Homeway.com Chinese percussion instrument L connect to form the warning indicating circuit.
The utlity model has simple in structure, install additional conveniently, sensitive reliable, antijamming capability is strong, can be before engine start instant sensed water level and reporting to the police.Especially for the oversize vehicle of rear engine, even sensor lead is long, contact resistance is big, also can work reliably.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.Vcc connects vehicle power supply among the figure; CG is a level sensor; SX is a water tank.
Embodiment
Be further described with regard to its circuit formation and principle of work below in conjunction with accompanying drawing:
Connected to form by water level detection circuit, feed circuit and warning indicating circuit three parts, wherein time base circuit IC, resistance R 1, capacitor C 2 and level sensor C G connect to form water level detection circuit; Connect to form the feed circuit of water level detection circuit by resistance R 2, capacitor C 1 and voltage stabilizing diode DW; Resistance R 3, triode T, alarm lamp DD Homeway.com Chinese percussion instrument L connect to form the warning indicating circuit.
Principle is as follows: resistance R 1 is formed voltage divider with sensor C G, when engine not during lack of water, the electrode of sensor C G does not have in the entry, time base circuit IC (NE555) circuit input end 2 pin are low level, output terminal 3 pin then present high level, therefore transistor T ends, and alarm lamp DD Homeway.com Chinese percussion instrument L does not all work.In case engine lack of water, the electrode of sensor C G be not in water, at this moment input end 6 pin are high level, and output terminal 3 pin then are transformed into low level, transistor T saturation conduction, alarm lamp DD Homeway.com Chinese percussion instrument L all electric work, send alerting signal.Because 555 circuit, 2 pin voltages will be lower than 1/3Vc c, 6 pin voltages will be higher than 2/3V c c and could overturn, so external disturbance is difficult for causing the false triggering of this circuit, and it is very reliable to work.
