Abstract
The utility model discloses a lead-acid storage battery hydrogen elimination device for an electric moped. The lead-acid storage battery hydrogen elimination device comprises a battery upper cover, wherein the battery upper cover is provided with a gas exhausting valve; the battery upper cover is provided with an acid filtering sheet for filtering sulfuric acid electrolyte, which is close to the gas exhausting valve; the battery upper cover is provided with a gas exhausting channel through which gas exhausted by the gas exhausting valve passes; a hydrogen storage alloy for absorbing hydrogen is arranged at the tail end of the gas exhausting channel; a gas exhausting hole for directly exhausting the hydrogen which cannot be absorbed by the hydrogen storage alloy is arranged beside the hydrogen storage alloy. According to the lead-acid storage battery hydrogen elimination device for the electric moped, the hydrogen storage alloy is used for absorbing the hydrogen so as to reduce the content of the hydrogen in the gas exhausted by the battery; the hydrogen accumulated in a battery box cannot reach a content range of hydrogen explosion; the lead-acid storage battery hydrogen elimination device is simple in structure and good in hydrogen elimination effect and the problem that the electric moped is exploded and combusted is solved.
Description
Technical field
The utility model relates to electric boosted automobile-used lead acid accumulator, relates in particular to the dehydrogenation unit on lead acid accumulator.
Background technology
Be accompanied by the fast development of electric bicycle industry, lead-acid accumulator for electric bicycle usage quantity is also being on the increase.Because lead acid accumulator can produce oxygen at the not phase positive pole that charges, negative pole can produce hydrogen, after the inherent charging of accumulator box for electric bicycle, can produce hydrogen and oxygen and accumulation.Due to power lock, start the reasons such as sparking, the loosening sparking of connecting line, often there will be the accidents such as battery explosion is on fire.Because summer temperature raises, this type of accident is on the increase simultaneously.
Lead acid accumulator consists of jointly positive plate, negative plate and electrolyte, and positive plate, after reaching plate oxygen overpotential, oxygen evolution reaction can occur; Negative plate can produce hydrogen after reaching overpotential for oxygen evolution.Due to electric bicycle used be analysing valve control type lead-acid accumulator battery, cell internal pressure is controlled by unidirectional valve, focuses on the release of to come after inside battery gas reaches certain pressure.Hydrogen is a kind of flammable explosive gas, and hydrogen and oxygen are explosive at the larger content range of 4%-76%.So exist larger potential safety hazard on the utility theory of analysing valve control type lead-acid accumulator battery on electric bicycle.
In order to eliminate these potential safety hazards, notification number is that the Chinese utility model patent of CN2556794 discloses a kind of hydrogen-removing safety valve for valve control type sealed lead acid battery on June 18th, 2003, in valve body bottom, to be provided with a Xiao Qing chamber that is wherein filled with palladium catalyst, in the valve hole at Xiao Qingshi top, be provided with a burst disk, in valve body central through hole, towards valve body upper port, be extended with an annular boss vertically, one lip valve retaining ring is on annular boss, in the valve body central through hole of Chun Fa upper end, by 2 piece pressing clips, one burst disk is housed, in valve body upper port, one plastic cap is installed.But its structure is not only complicated, and the hydrogen effect that disappears is good not.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of electric boosted automobile-used lead acid accumulator dehydrogenation unit, and simplified structure improves the hydrogen effect that disappears.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of electric boosted automobile-used lead acid accumulator dehydrogenation unit, comprise cell cover, described cell cover is provided with vent valve, described cell cover adjacent rows air valve is provided with the filter acid film that filters sulfuric acid electrolyte, described cell cover is provided with the exhaust passage of passing through for vent valve Exhaust Gas, described exhaust passage end is provided with the hydrogen bearing alloy that absorbs hydrogen, and described hydrogen bearing alloy side is provided with the direct steam vent of discharging of the oxygen that hydrogen bearing alloy cannot be absorbed.
Preferably, described vent valve is provided with four, and four vent valves are positioned at four jiaos an of rectangle, and described exhaust passage is that " ［ " type distributes four vent valves are connected in turn.
Preferably, described upper cover middle part is provided with a rectangle deep gouge, and described four vent valves are located at the right-hand part of deep gouge, and described rectangle deep gouge is sealed by large cover plate.
Preferably, described cell cover is provided with a groove at middle part, rectangle deep gouge the place ahead, and described hydrogen bearing alloy is positioned at this groove, and described groove is provided with a tegillum sheet sealing.
Preferably, described filter acid film is ring-type and is fastened on vent valve outer circumferential sides.
The utility model utilizes hydrogen bearing alloy to absorb hydrogen, reduces hydrogen content in battery Exhaust Gas, makes hydrogen in battery case build up the content range that does not reach hydrogen explosion, and simple in structure, the hydrogen that disappears is effective, has solved the problem of electric bicycle explosive combustion.
