Abstract
The utility model discloses a liquid level alarm device of engine cooling fluid. The liquid level alarm device comprises an expansion tank and a storage battery, and is characterized in that the liquid level alarm device comprises a liquid level sensor, a controller, a safety switch and one or more alarm elements; the liquid level sensor is mounted on the side wall of the expansion tank, contacted with the cavity of the expansion tank and connected with the input terminal of the controller through a lead; the controller is connected with the storage battery and the safety switch in series through a lead; and the alarm element is connected between the output terminal of the controller and the storage battery through a lead. The utility model has the advantages of simple and compact structure, high reliability, low cost, high detection precision, good university, strong practicability, and convenient installation and debugging.
Description
Technical field
The utility model relates to a kind of liquid level alarm device that is used for the detection of engine cooling liquid.
Background technique
At present, motor on the truck crane does not have the liquid level alarm device of detection of engine cooling liquid, when the cooling liquid liquid level in the motor expansion tank is crossed when low, because no cooling liquid liquid level alarm device makes the user can't in time replenish engine coolant, cause engine overheat, working procedure worsens, and part strength reduces, and machine oil is rotten, the generation of phenomenons such as parts depreciation aggravation finally causes comprehensive decline of engine power performance, Economy, reliability and durability.
The model utility content
The purpose of this utility model is the above-mentioned deficiency at prior art, a kind of liquid level alarm device of engine coolant is provided, it have simple in structure, compact, reliability is high, with low cost, testing precision is high, versatility good, real-time, Installation and Debugging advantage easily.
For achieving the above object, the liquid level alarm device of engine coolant of the present utility model, comprise expansion tank, storage battery, it is characterized in that also comprising liquid level sensor, controller, insurance, switch, one or more alarm element, liquid level sensor is installed on the sidewall of expansion tank and with its inner chamber and contacts, liquid level sensor links to each other with the input end of controller by lead, controller is connected by lead with storage battery, switch, insurance, and alarm element is connected between the output terminal and storage battery of controller by lead.
Above-mentioned alarm element can be buzzer;
Above-mentioned alarm element also can be flashing trafficator;
Working principle of the present utility model: when the cooling liquid in the expansion tank is higher than the probe of liquid level sensor, the numerical value of resistance value for surveying of liquid level sensor output, controller output low level, alarm element attonity; When the cooling liquid in the expansion tank was lower than the probe of liquid level sensor, the resistance value of liquid level sensor output was infinitely great, controller output high level, and alarm element sends signal, the prompting supervisor;
As further improvement of the utility model, described alarm element is buzzer and flashing trafficator, and the two is connected in parallel between the output terminal and storage battery of controller by lead, and is installed in the operator cabin; Can increase safety factor, and be convenient to observe.
In sum, the utlity model has simple in structure, compact, reliability is high, with low cost, testing precision is high, versatility good, real-time, Installation and Debugging advantage easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
By shown in Figure 1, the liquid level alarm device of this engine coolant, comprise expansion tank 1, storage battery 2, liquid level sensor 3, controller 4, insurance 5, switch 6, buzzer 7 and flashing trafficator 8, liquid level sensor 3 is installed on the sidewall of expansion tank 1 and with its inner chamber and contacts, liquid level sensor 2 links to each other by the input end of lead with controller 4, controller 4 and storage battery 2, switch 6, insurance 5 are connected by lead, buzzer 7 and flashing trafficator 8 are connected in parallel between the output terminal and storage battery 2 of controller 4 by lead, and are installed in the operator cabin;
During use, Closing Switch 6, storage battery 2, switch 6, insurance 5, controller 4 form series loop by lead; When the cooling liquid in the expansion tank 1 is higher than the probe of liquid level sensor 3, the numerical value of resistance value for surveying of liquid level sensor 3 outputs, controller 4 output low levels, the buzzer 7 that is installed in the operator cabin does not pipe flashing trafficator 8 flicker frees; When the cooling liquid in the expansion tank 1 is lower than the probe of liquid level sensor 3, the resistance value of liquid level sensor 3 outputs is infinitely great, controller 4 output high level, the buzzer 7 that is installed in the operator cabin pipes, flashing trafficator 8 flickers, remind the user in time to replenish engine coolant, avoid engine overheat, working procedure worsens, and part strength reduces, machine oil is rotten, the generation of phenomenons such as parts depreciation aggravation.
