Description
Technical field
The utility model relates to sealed lead acid storage battery technical field, relates in particular to a kind of maintainable sealed lead acid storage battery.
Background technology
Storage battery is the requisite part of automobile, can be divided into traditional lead acid accumulator and non-maintaining type storage battery.Lead acid accumulator forms by positive/negative plate, dividing plate, housing, electrolyte and wiring pile are first-class, the chemical reaction of its electric discharge is to rely on positive plate active material and positive and negative pole active matter to carry out under the effect of electrolyte (dilution heat of sulfuric acid), and wherein the grid frame of pole plate is to manufacture with lead-antimony alloy.Maintenance free cell is due to the advantage in self structure, and the consumption of electrolyte is very little, does not substantially need to supplement distilled water within useful life.It also has feature shatter-proof, high temperature resistant, that volume is little, self discharge is little.Be generally the twice of conventional accumulators useful life.
Existing Automobile Lead Acid Batteries is divided into two kinds: the first is plain edition storage battery, and another kind is maintenance-free lead accumulator.When maintenance-free lead accumulator itself dispatches from the factory, just added electrolyte and shut, user not can add supplementary liquid.
Automobile sealed lead-acid accumulator free from maintenance, in actual use, due to the nearly engine of some vehicle storage battery installation position offset, ambient temperature is higher, and vehicle is long distance travel often, the reason such as overcharge that charging voltage is higher, easily cause storage battery dehydration, make life-span premature termination.
Utility model content
The problem existing for overcoming existing sealed lead-acid accumulator free from maintenance, the utility model provides a kind of maintainable sealed lead acid storage battery convenient and practical, simple in structure, this storage battery, with liquid filling hole, can add water to storage battery and safeguard, to extend the useful life of storage battery.
A kind of maintainable sealed lead acid storage battery, comprise battery cap, described battery cap comprises the middle cover with liquid injection hole, and the upper cover covering in covering, described upper cover has the liquid filling hole corresponding with described liquid injection hole position, in described liquid filling hole, is plugged with sealing bolt.
Existing maintenance-free lead accumulator all can not add supplementary liquid to be safeguarded, but in actual use, the storage battery of part vehicle is due to close automobile engine, and ambient temperature is higher, causes storage battery dehydration more, need to scrap replacing, but now the internal storage battery pole plate life-span does not stop, if add appropriate supplementary liquid, can proceed to use, but existing maintenance-free lead accumulator is not provided with liquid injection hole, cannot adds water and supplement.
For above-mentioned problem, the utility model provides a kind of maintainable sealed lead acid storage battery, in this storage battery, be covered with liquid injection hole, upper cover has the liquid filling hole corresponding with liquid injection hole position, and liquid filling hole utilizes sealing bolt shutoff, when sealed lead acid storage battery occurs in the too much situation of dehydration, can add water by opening encapsulation bolt and supplement, to extend the useful life of storage battery, reduce frequency and cost that storage battery is changed.
As preferably, described sealing bolt threaded engagement is in liquid filling hole.
Sealing bolt in the technical program is detachable block, for ease of the unlatching of sealing bolt, does not generally adopt the friction tight connected modes such as interference fit, and therefore, preferred sealing bolt and liquid filling hole pass through threaded engagement.
As preferably, the end face of described sealing bolt is provided with the triangular groove for opening.
The end face of conventional sealing bolt is with flat recess or the cross recess being convenient to open, but ordinary consumer is in opening storage battery process, if misoperation, easily there is security incident, therefore,, for preventing that the improper of storage battery from opening, the utility model is offered triangular groove at the end face of sealing bolt, need special-purpose instrument just can open, can promote the handling safety in maintenance process.
As preferably, described liquid filling hole inwall is provided with annular brace step, and the outer wall of described sealing bolt is provided with the spacing preiection coordinating with described annular brace step, between described annular brace step and spacing preiection, is provided with sealing ring.
As preferably, described middle hd top face is provided with irregular lower clapboard, and upper cover bottom surface is provided with the upper spacer adapting with described lower clapboard, and described lower clapboard and upper spacer fasten the gas passage that forms labyrinth structure.
Further preferred, cover in described and be also provided with return port, the surrounding of described return port is provided with backflow inclined-plane.
The gas passage of labyrinth structure has effectively increased the flow path of gas, facilitates gas cooled; Backflow ramp facilitates cooling liquid backflow inner to cell body.
The utility model is convenient and practical, simple in structure, and is convenient to processing; The liquid filling hole of arranging is beneficial to the liquid feeding of storage battery and safeguards, extends the useful life of storage battery, can reduce frequency and cost that storage battery is changed, to reduce the waste of resource.
