Abstract

An automatic alarming device for over-low liquid level of automobile storage battery electrolyte comprises lead rod sensors (3), a triode transistor tandem switch, a composite tube and an alarm L, wherein the lead rod sensors (3) are respectively arranged in each single-cell battery (2) of the storage battery and are used for detecting whether the liquid level height of electrolyte of each single-cell battery is normal or not; when the heights of the electrolyte of all single-cell batteries (2) are normal or the liquid level height of the electrolyte of one single-cell battery is abnormal, the triode transistor tandem switch can be conducted or cut off; and when the triode transistor tandem switch is conducted or cut off, the composite tube can be cut off or conducted; and when the composite tube is conducted, the alarm L can alarm. The automatic alarming device disclosed by the utility model has the advantages of simple structure, low mounting expenses and low cost.

Description

The too low autoalarm of automobile storage battery electrolyte level

Technical field

The utility model relates to a kind of warning device, is the too low autoalarm of a kind of automobile storage battery electrolyte level specifically.

Background technology

Accumulator is the power producer of running car starting, and the accumulator working service is improper will reduce its serviceable life, forms various faults, the safety of impact driving.Check that the electrolysis liquid surface height is different with interval time in winter in summer, if it is too low to grasp the improper liquid level that causes, the usability of battery can be affected, but frequent dismounting inspection brings inconvenience to our work, also affect staff's work efficiency, therefore develop the too low warning device of accumulator liquid level, lower than regulation during liquid level, alarm lamp is bright when single lattice electrolytic solution liquid level, remind the staff to take measures, can give like this our work and life brings comfortable and convenient.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, erected cost is little, cost is low too low autoalarm of automobile storage battery electrolyte level, can install and use at all kinds vehicle.

The too low autoalarm of automobile storage battery electrolyte level that the utility model provides, it comprises:

Be arranged in each single lattice battery of accumulator, whether the electrolytic solution liquid level that is used for detecting each single lattice battery normal lead rod sensor;

Normal or when having one of them undesired when the electrolytic solution liquid level of all single lattice batteries, but the transistor tandem tap of conducting or cut-off;

The conducting of transistor tandem tap or when cut-off, can end or the complex pipe of conducting; And

The alarm that can report to the police during the complex pipe conducting.

The transistor tandem tap is comprised of with the transistor that the lead rod sensor equates quantity, the base stage of each transistor is connected with the lead rod sensor respectively, each transistor is connected with the collector of another transistor by emitter successively, the collector of first transistor connects the positive pole of accumulator, and the emitter of last transistor is connected with the negative pole of accumulator.

The utility model can reduce loaded down with trivial details dismounting number of times in checking battery-fluid level height process, greatly reduces staff's workload, the fault that can avoid accumulator to cause because electrolysis liquid surface is too low.

The utility model in use, when the battery cell liquid level bright lower than assigned position Times warning lamp, to show that battery liquid is not enough, can remind the staff to take measures, check the numerous dismounting number of times of accumulator liquid level time-frequency to reduce, increase work efficiency, the fault that can avoid accumulator to cause because electrolyte level is too low, be conducive to improve the ride safety of automobile performance, give our work and life brings comfortable and convenient.The utility model is simple in structure, and its erected cost is little, and cost is low, and simple and easy to do, has good society generalization using value.

Description of drawings

Fig. 1 is circuit theory diagrams of the present utility model.

Embodiment

With reference to Fig. 1, use the common lead accumulator that is in series by 6 single lattice batteries as example take automobile, each single lattice cell voltage is about 2 volts.

article 6, lead rod sensor 3 is respectively in 6 single lattice batteries 2 of accumulator 1, 6 transistor VT1 that the transistor tandem tap is equated with lead rod sensor 3 by quantity, VT2, VT3, VT4, VT5 and VT6 form, the base stage of each transistor is connected with lead rod sensor 3 respectively, each transistor is connected with the collector of another transistor by emitter successively, the collector of first transistor VT1 connects the positive pole of accumulator 1 through automobile ignition switch K, and the emitter of last transistor VT6 is connected with the negative pole of accumulator 1 with R2 through shunt resistance R1.

Complex pipe is comprised of two triode VT7, VT8, connects with dropping resistor R3 after shunt resistance R1 and R2 parallel connection, and dropping resistor R3 connects the base stage of triode VT7 again, complex pipe conducting alarm device L work, and alarm L is alarm lamp.

Owing to there being electrolytic solution to exist, form potential difference (PD) between anode and negative electrode in accumulator 1.

Connect the igniting K switch, when the every single lattice battery 2 electrolysis liquid surface height of accumulator 1 are all normal, all produce potential difference (PD) between lead rod sensor 3 and negative electrode, the condition of each the transistor conducting in the transistor tandem tap is provided, the complex pipe cut-off, alarm lamp does not work, and illustrates that the every lattice electrolyte level of accumulator height is normal.

single lattice battery 2 in accumulator 1 adds the water liquid level to be had when one highly the end reaches normal amount, because the lead rod sensor 3 of correspondence is not immersed in battery liquid, do not form potential difference (PD) between this lead rod sensor 3 and accumulator 1 negative pole, cause the transistor base stage that connects with this lead rod sensor 3 identical with the emitter current potential, do not have electric current to pass through in base stage, can not form the condition of transistor tandem tap conducting, at this moment, the complex pipe conducting, alarm lamp is bright, illustrate single lattice battery 2 in accumulator 1 add the water liquid level have at least one undesired, can remind the staff to take measures.
