Abstract
The invention provides an upper cover and cover piece of an electrolyte-overflowing-preventing structure of a storage battery and relates to storage batteries. At present, structural matching of the upper cover and the cover piece of the storage battery for solving electrolyte overflowing and acidic gas corrosion in a storage battery charging/discharging process is a main research direction. Aiming at the problem, a common solution adopted in the industry is that the matching tightness of the upper cover of the storage battery and the cover piece is enhanced, so that electrolyte or acidic gas in a shell is prevented from overflowing from a storage battery cover; however, the effect is not ideal, and the poor exhausting and thermal runaway can be easily caused in the shell, so that the service life of the storage battery is shortened. The upper cover and cover piece of the electrolyte-overflowing-preventing structure of the storage battery is characterized in that a rectangular exhausting groove in the upper surface of the upper cover is internally provided with an annular separation wall for surrounding a liquid injection hole; exhausting holes in the upper parts of side walls at the two ends of the exhausting groove are communicated with cuboid-shaped spaces, which laterally protrude outwards, at the two ends of the upper cover; one surface of a rectangular cover body of the cover piece is vertically connected with an annular clamping groove; and the clamping groove can be nested into the separation wall. The upper cover and cover piece of the electrolyte-overflowing-preventing structure of the storage battery has the beneficial effects of electrolyte-overflowing and corrosion prevention, flexible structure match and good exhausting property.
Description
Technical field
The present invention relates to storage battery, is a kind of storage battery seepage prevention structure upper cover and cover plate thereof more specifically.
Background technology
At present, storage battery specification kind on domestic and international storage battery market is day by day various, housing (containing cell jar, Storage Battery Top Cover, cover plate, the handle etc.) technical quality that storage battery is produced in assembling requires also more and more higher, and especially the respective outer side edges of battery cap (Storage Battery Top Cover and cover plate) solves the main direction of studying of electrolyte discharge, acid gas corrosion in accumulator charging/discharging process especially.
For this kind of problem, the solution of existing general employing is the cooperation compactness increasing Storage Battery Top Cover and cover plate in the industry, the electrolyte of accumulator housing inside or acid gas is avoided to overflow from battery cap, but the method effect is undesirable, cure the symptoms, not the disease, and easily cause exhaust in accumulator housing bad, then form thermal runaway, cause the life of storage battery to shorten.
Summary of the invention
The object of this invention is to provide a kind of storage battery seepage prevention structure upper cover and cover plate thereof, the deficiency of electrolyte discharge and acid gas corrosion in accumulator charging/discharging process can be overcome, have the advantages that seepage prevention burn into respective outer side edges is flexible, venting quality is good.
The present invention realizes in the following way: a kind of storage battery seepage prevention structure upper cover and cover plate thereof, it is characterized in that: in the rectangle exhaust groove of upper cover upper surface, have the ring wall around liquid injection hole, the side wall upper part at exhaust groove two ends has steam vent to be communicated with the rectangular parallelepiped space of the external side leakage in upper cover two ends, cover plate rectangle lid one side on be vertically connected with annular slot, draw-in groove can with partition wall nested encryptions.
During concrete enforcement, upper cover and cover plate assemble all-in-one-piece battery cap by the nested arrangements of partition wall and draw-in groove, and battery cap and cell jar are fitted together by rubber seal in industry or heat-sealable way.In the acid filling of storage battery changes into the stage or finished battery uses, the electrolyte of cell jar inside is because filling dosage is too much or the compressing of chemical reaction air pressure forms liquid level rising, electrolyte and corrosion sour gas is caused to overflow from liquid injection hole, the partition wall that the electrolyte overflowed can be centered around around liquid injection hole stops, thus avoid the undesirable condition that traditional storage battery electrolyte overflows in exhaust groove and occur, the corrosion sour gas overflowed then discharges battery jar outside through the steam vent of exhaust groove two ends side wall upper part, avoid the excessive corrosion impact to battery jar outward appearance of corrosion sour gas, play the effect that venting quality is good simultaneously, avoid because the internal storage battery air pressure of the bad generation of exhaust is excessive or the too high thermal runaway phenomenon caused of heat occurs.
The invention has the beneficial effects as follows: a kind of storage battery seepage prevention structure upper cover of the present invention and cover plate thereof, have the advantage that seepage prevention burn into respective outer side edges is flexible, venting quality is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is superstructure schematic diagram.
Fig. 2 is cover plate structural representation.
Fig. 3 is that battery cap coordinates schematic diagram with cell jar.
In figure, 1. exhaust groove, 2. steam vent, 3. liquid injection hole, 4. partition wall, 5. draw-in groove, 6. lid, 7. battery cap, 8. cell jar.
Embodiment
In Fig. 3 schematic diagram, in Fig. 1, in upper cover and Fig. 2, cover plate assembles all-in-one-piece battery cap (7) by the nested arrangements of draw-in groove (5) on partition wall (4) and lid (6) one side, and battery cap (7) and cell jar (8) are fitted together by rubber seal in industry or heat-sealable way.
The stage is changed in the acid filling of storage battery, the electrolyte of cell jar (8) inside is because filling dosage is too much or the compressing of chemical reaction air pressure forms liquid level rising, electrolyte and corrosion sour gas is caused to overflow from liquid injection hole (3), the electrolyte overflowed can be centered around liquid injection hole (3) partition wall (4) around and stop, thus the undesirable condition avoiding traditional storage battery electrolyte spilling in exhaust groove (1) occurs, the corrosion sour gas overflowed then discharges battery jar outside through the steam vent (2) of exhaust groove (1) two ends side wall upper part, avoid the excessive corrosion impact to battery jar outward appearance of corrosion sour gas.
Complete finished product at storage battery to make, when the storage battery of finished product uses, the electrolyte of the electrochemical reaction generation that cell jar (8) is inner and corrosion sour gas overflow from liquid injection hole (3), the electrolyte overflowed can be centered around liquid injection hole (3) partition wall (4) around and stop, the corrosion sour gas overflowed then discharges battery jar outside through the steam vent (2) of exhaust groove (1) two ends side wall upper part, thus play the good effect of venting quality, avoid because the internal storage battery air pressure of the bad generation of exhaust is excessive or the too high thermal runaway phenomenon caused of heat occurs.
Claims (1)
1. a storage battery seepage prevention structure upper cover and cover plate thereof, it is characterized in that: in the rectangle exhaust groove of upper cover upper surface, have the ring wall around liquid injection hole, the side wall upper part at exhaust groove two ends has steam vent to be communicated with the rectangular parallelepiped space of the external side leakage in upper cover two ends, cover plate rectangle lid one side on be vertically connected with annular slot, draw-in groove can with partition wall nested encryptions.
