Abstract
The utility model discloses a secondary explosion-proof device of a storage battery, relates to a safety protection device of the storage battery, in particular to an explosion-proof exhaust device of the storage device, and mainly solves the known problems that the battery is blown up or even explodes due to temperature generated in the use or charge-discharge processes of the storage battery and the storage battery with the capacity larger than 50Ah is scrapped once the explosion-proof device arranged on the storage battery is started due to the fact that the explosion-proof device is disposable. The secondary explosion-proof device is characterized in that a valve body is fixed on a battery cover plate, a middle hole communicated with the interior of the battery is arranged on the valve body, and an explosion-proof cover is connected onto the valve body; a sealing gasket, a press plate and a spring are arranged between the explosion-proof cover and the valve body; and a through hole is formed in the explosion-proof cover in the axial direction. An explosion-proof valve is arranged on the storage cover plate, the middle hole formed in the valve body is opened to discharge air in the battery when pressure in the battery is larger than the set value and is sealed when pressure in the battery is smaller than the set value, and therefore scrapping of the battery due to explosion caused by too much pressure in the battery is avoided.
Description
Technical field
The utility model relates to the safety guard of storage battery, specifically relates to the exhaust apparatus of secondary battery anti-explosion.
Background technology
Present storage battery is at charging and discharging or make the certain temperature of generation that the used time all can be more or less, and can not guarantee that in the battery production process moisture in battery core is processed clean completely, produce gas so can cause the decomposition of electrolyte, the slight internal resistance of cell that causes increases, the battery blow-up, serious meeting causes battery explosion, thereby produces security incident.What now the battery capacity on market surpassed 50Ah all is equipped with explosion-protection equipment basically, but is all disposable.Because the cost of jumbo storage battery is very high, if battery starts explosion-protection equipment because of the inner gas that produces, although safety, owing to being disposable, storage battery is scrapped.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and the storage battery that proposes discharge and recharge or use procedure in, the gas that internal storage battery produces reaches the certain pressure of a certain amount of rear generation and can automatically discharge, then continue to use, can not set off an explosion and storage battery is scrapped, can not affect the quality of storage battery and the storage battery secondary explosion-protection equipment in life-span.
Technical solution of the present utility model is: a kind of storage battery secondary explosion-protection equipment is: be fixed with valve body on cover plate of storage battery, valve body is provided with the mesopore that is connected with inside battery, be connected with Explosion-proof cap on valve body, be provided with sealing gasket, compressing tablet and spring between Explosion-proof cap and valve body, Explosion-proof cap is provided with through hole vertically.
Explosion-proof cap described in technical solution of the present utility model is connected on valve body by the internal thread on it.
Spring described in technical solution of the present utility model is Pagoda-shaped, and an end of spring is connected on valve body by compressing tablet and sealing gasket, and the other end withstands in Explosion-proof cap.
the utility model is to add an explosion-proof valve in the middle of the conductive pole of the positive pole of existing cover plate of storage battery and negative pole, it is mainly by the polytetrafluoroethylene valve body, the butyl rubber sealing gasket, the stainless steel compressing tablet, stainless steel spring and ABS Explosion-proof cap form, the pressure of design is 2kg, when internal storage battery pressure reaches 2kg, stainless steel spring can shrink because of pressure, inside battery gas is discharged, when internal storage battery pressure during less than 2kg, stainless steel spring restores to the original state, battery continues sealing, keep the pressure of inside battery always less than 2kg, thereby make storage battery discharge and recharge or use procedure in as while occurring that cell internal pressure is excessive, can not set off an explosion and scrap.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, be provided with an explosion-proof valve between the positive and negative electrode conductive pole on battery cover board 2, explosion-proof valve comprises valve body 6 and Explosion-proof cap 1, valve body 6 is fixed on battery cover board 2, form an integral body with battery cover board 2, be provided with on valve body 6 with battery in the mesopore that is connected, valve body 6 adopts polytetrafluoroethylmaterial materials injection molded together with battery cover board 2; Explosion-proof cap 1 is a lid that is provided with vertically through hole, Explosion-proof cap 1 is connected on valve body 6 by internal thread, be provided with stage clip 3 between Explosion-proof cap 1 and valve body 6, compressing tablet 4 and sealing gasket 5, stage clip 3 adopts the Pagoda-shaped spring, one side pressure on compressing tablet 4, is connected with sealing gasket and is connected with valve body 6 by compressing tablet 4, and the other end of stage clip 3 withstands in Explosion-proof cap 1; Sealing gasket 5 adopts good seal performance and corrosion resistant butyl rubber material to make, and compressing tablet 4 and spring 3 adopt stainless steel material, and Explosion-proof cap 1 adopts the injection mo(u)lding of high, the lightweight ABS material of hardness; Operation principle: when battery when discharging and recharging, if cell internal pressure surpasses set point, gas in battery is discharged from the mesopore on valve body 6, the spring 3 that is located between valve body 6 and Explosion-proof cap 1 is shunk, mesopore and through hole Explosion-proof cap 1 on of gas from valve body 6 discharged outside battery, and during less than set point, spring 3 restores when cell internal pressure, the sealing of mesopore on valve body 6, thus avoided that cell internal pressure is excessive to be caused battery explosion and scrap.
