Description
Technical field
The invention belongs to battery technology field, relating to a kind of automobile with safeguarding lead acid accumulator less.
Background technology
Safeguard that lead acid accumulator is the main lead acid accumulator of one that current automobile uses less, its battery case is made up of cell jar, battery cap and blow-cook, and blow-cook is fixed on battery cap by thread seal.Based on national environmental protection and updating and upgrading of a product requirement, the gas that regulation storage battery produces could be discharged after having to pass through filtration, and requires that battery external and internal pressure is inconsistent.For this problem, existing scheme is generally increase polytetrafluoroethylene filter vapour sheet to the blow-cook inside of lead acid accumulator, and gas after filter vapour sheet filters, then discharges battery.The hydrogen produced in battery operation and oxygen, a part is disposed to outside storage battery by blow-cook, and a part is then gathered in internal storage battery.The weak point of this solution is: safeguard that lead acid accumulator generally adopts lead-antimony alloy less, this battery gassing rate is large, and polytetrafluoroethylene filter vapour sheet is obviously deteriorated by the wetting rear venting capability of water vapour, inside battery hydrogen and oxygen mixed gas pressure is caused to raise, when inside battery or outside generation spark, produce accumulator explosion event, explosion time impulsive force can cause battery cell case and the exhaust cracked separation of fragments of stopper and acid solution to splash, and cause any property loss even personal injury.
Summary of the invention
Object of the present invention solves the above-mentioned problems in the prior art exactly, provides one effectively can filter acid mist, can prevent outside burning things which may cause a fire disaster and ignite battery, significantly reduces the explosion-proof type lead acid accumulator that inside spark ignites the extent of injury of battery.
For achieving the above object, technical solution of the present invention is: a kind of explosion-proof type lead acid accumulator, and it comprises cell jar, battery cap, pole group, electrolyte, blow-cook and safety pad; Battery cap is single-layer cover, and cell jar and battery cap adopt high tenacity PP injection molding, and both are connected together by hot-seal adhesive; Ge Ji group is connected by cross wall welding, and blow-cook thread seal is fixed on the liquid injection hole of battery cap; Safety pad is placed in above the group of pole, floats over the electrolyte surface immediately below liquid injection hole.
Blow-cook described above comprises key, stopper and filter vapour sheet; Key is the hollow structure having bottom surface and sidewall; Key and stopper are by chain connection, and stopper is fastened on key top, and with key tight fit; Its bottom center is provided with multiple venting of dust explosion hole, and middle and lower part is provided with buffer air chamber, and middle and lower part outer wall is provided with screw thread, and middle part is provided with the support rim installing filter vapour sheet, and filter vapour sheet is placed on support rim; Stopper bottom is provided with annular boss, and annular boss presses filter vapour sheet edge, and annular boss is provided with air vent hole, and key sidewall is provided with steam vent.
Steam vent described above is two, is symmetricly set on the key sidewall of key and hinge connection lower end; Described air vent hole is three, and three air vent holes are distributed in annular boss away from the semicircular ring of steam vent.
