Abstract

The utility model relates to a protector for a lead-acid accumulator, which can effectively extend the service life of the lead-acid accumulator. The utility model comprises a square wave generating circuit and a positive negative pulse circuit. The square wave generating circuit generates a square signal with a frequency up to the mark, and the square wave can be added to both ends of the accumulator in pulse manner by the positive negative pulse circuit in order to prevent and eliminate the crystallized sulfide on an accumulator pole plate. Consequently, the utility model extends the service of the accumulator.

Description

A kind of lead-acid accumulator protecting device

Affiliated technical field

The utility model relates to a kind of lead-acid accumulator protecting device, and this protector can effectively prolong the useful life of lead acid accumulator.

Background technology

Lead acid accumulator is with a long history, stable performance.Be widely used in fields such as automobile, communication, broadcasting and TV, IT, electric power, railway, aviation, harbour, military affairs, finance, the energy, demand is extensive, and consumption is huge.But no matter existing all kinds of lead acid accumulator products are homemade or import, just easily produce phenomenons such as charging difficulty, capacity reduction usually in useful life, and premature failure is scrapped, and can't use.This is our difficult problem of puzzlement always.

Normal storage battery is after discharge, and the active material on the positive/negative plate mostly becomes the little crystallization of soft lead sulfate, is evenly distributed in the pole plate, reverts to original brown lead oxide and spongy lead easily when charging, and this is a kind of sulfation normally.Because battery improper use, long-term undercharge, or half discharge condition, over-discharge or the discharge untimely charging in back, internal short-circuit, density of electrolyte is too high, the temperature height, and liquid level hangs down the problems such as pole plate exposes that make, cause the undesired generation of chemical reaction in the battery, on pole plate, formed thick lead sulfate crystallization, this crystallization poorly conductive, volume is big, also can stop up the micropore of pole plate, hinder the osmosis of electrolyte, increased the internal resistance of cell, when charging, be difficult to recover, become irreversible lead sulfate, the active material of participating in electrochemical reaction in the pole plate is reduced, so battery capacity reduce the battery sulfation that Here it is often says greatly.In fact, in the lead acid accumulator that inefficacy is scrapped, so long as regular producer by standard production and on-mechanical damage (as pole plate come off, internal break, short circuit etc.), all can remove plate vulcanizing.

Summary of the invention

The utility model is specifically designed to eliminates problem and the fault that the sulfide crystallization salinization on the polar plate of lead acid storage battery causes.It can remove the crystallization sulfide on the battery pole plates continuously, and can prevent effectively that new crystallization sulfide from producing, and has fundamentally improved the service behaviour of lead acid accumulator, makes accumulator plate be brand-new and efficient operation state all the time.The capacity output that recovery and assurance storage battery are stable, the operating efficiency of raising storage battery extends the life of a cell greatly, scraps quantity, preserve the ecological environment good social benefit, economic benefit and environmental benefit to reducing battery.

The technical scheme that its technical problem that solves the utility model adopts is: this utility model comprises square wave generation circuit, the positive negative pulse stuffing circuit is formed, it is characterized in that the positive negative pulse stuffing circuit is by triode T2, T3, resistance R 7, R8, R9, R10 and capacitor C 3 are formed, T2 is a NPN triode, T3 is a PNP triode, the base stage of T2 links to each other with square wave generation circuit output end by a resistance, the grounded emitter of T2, the collector electrode of T2 links to each other by the base stage of resistance R 7 and T3, the collector electrode of T3 is by R9 ground connection, the emitter of T3 connects battery positive voltage by R8, and the emitter positive pole that the negative pole of capacitor C 3 meets T3 connects battery positive voltage by R10, and ground links to each other with battery terminal negative; The utility model is to produce the satisfactory square-wave signal of frequency by square wave generation circuit, and by the positive negative pulse stuffing circuit square-wave pulse is added to the two ends of storage battery, stoping and to eliminate crystallization sulfide on the battery pole plates, thereby extends the life of a cell.

Description of drawings

Below in conjunction with accompanying drawing, implementation procedure of the present utility model is further specified.

Fig. 1 is a schematic diagram of the present utility model.

Embodiment

Square wave generation circuit is by triode T0 among the figure, T1, resistance R 2, R3, R4, R5, capacitor C 1, C2 forms, the positive negative pulse stuffing circuit is by triode T2, T3, resistance R 7, R8, R9, R10 and capacitor C 3 are formed, T2 is a NPN triode, T3 is a PNP triode, and the base stage of T2 links to each other the grounded emitter of T2 by resistance R 6 with square wave generation circuit output end, the collector electrode of T2 links to each other by the base stage of resistance R 7 and T3, the collector electrode of T3 is by R9 ground connection, and the emitter of T3 connects battery positive voltage by R8, and the negative pole of capacitor C 3 connects the emitter of T3, positive pole connects battery positive voltage by R10, and ground links to each other with battery terminal negative; The utility model is to produce the satisfactory square-wave signal of frequency by square-wave pulse generation circuit, and square-wave pulse is added to the two ends of storage battery by the positive negative pulse stuffing circuit, with the crystallization sulfide on prevention and the elimination battery pole plates, thereby extend the life of a cell.

By above accompanying drawing, can understand this utility model principle and design feature.Characteristics such as the utlity model has simple in structurely, cost is low, and effect is obvious, and is practical reliable.
