Abstract
The utility model relates to a maintenance-free lead-acid storage battery which comprises a battery box, an upper cover, a separator, pole plates and terminals, wherein, the upper cover is spliced on the battery box; the separator is arranged in the battery box and divides the battery box into two simple lattices; the pole plates are respectively arranged in the simple lattices; the upper cover is provided with an air outlet which extends to be provided with a capillary facing the interior of the battery box; splashproof inner covers are respectively arranged between the battery box and the pole plates in the battery box. The utility model has the advantages of simplicity, reasonability, easy processing and manufacture, small loss amount of electrolyte, long service life and the like; the utility model can realize industrial production, is suitable for being used in adverse circumstances, such as under a coal mine and an underground mine, and can substitute the existing mine lithium batteries.
Description
Technical field
The utility model relates to a kind of storage battery, and refering in particular to is a kind of a kind of maintenance-free lead accumulator that is used for providing to lighting apparatus under colliery and other mine energy.
Background technology
Because lead acid accumulator is cheap, raw material is easy to get, dependable performance, reclaim easily and be suitable for characteristics such as heavy-current discharge, become output maximum in the world at present, purposes is storage battery the most widely, but present maintenance-free lead accumulator, generally be to adopt glue envelope or ultrasonic bonding at battery case and cell cover, loam cake is anchored on the battery case, perhaps battery case and cell cover adopt the connected mode of inserting, in the said structure owing to be the structure of sealing between battery case and the loam cake, in order to solve the problem of exhaust, usually on cell cover, open pore, generally only be only applicable to operational environment occasion stably, and incompatibility colliery and other mine provide the energy for workman's lighting apparatus, this mainly is owing to work under bad environment under the ore deposit, storage battery generally is to hang on miner's the health, therefore, motion with its health, storage battery shakes, the phenomenon that tilts happens occasionally, electrolyte might overflow from air vent hole, on the one hand, cause miner's health of burning easily, electronic component also there is corrosiveness, can't guarantees the performance of battery and workman's safety; On the other hand, the loss of electrolyte and excessive the volatilization also can cause the premature failure of storage battery.Therefore, traditional mining mains lighting supply generally adopts lithium battery, and the production cost of lithium battery is several times of lead acid accumulator, therefore, consider it is very non-remunerative from economic benefit, thus, design is produced and a kind ofly to be adapted to that illuminating lead acid accumulator has extensive market prospects undoubtedly under the ore deposit.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple and reasonable, and the electrolyte loss volatile quantity is little, and is safe in utilization, dependable performance, the maintenance-free lead accumulator of long service life.
The purpose of this utility model is achieved by following technical proposals:
A kind of maintenance-free lead accumulator, comprise battery case, loam cake, dividing plate, pole plate, terminals, described loam cake is inserted on the battery case, described dividing plate is arranged in the battery case, battery case is separated into two single lattice, pole plate is arranged in single lattice, covers on described and is provided with the gas outlet, and the gas outlet extends a capillary in battery case.
In the utility model, be provided with the splashproof inner cap between pole plate in described battery case and the battery case.
The utility model adopts technique scheme to have following advantage, owing to be provided with the capillary that is communicated with the gas outlet and directly be in communication with the outside last covering, on the one hand, the gas that produces in the time of can guaranteeing the battery charge and discharge escapes into outside the battery case by capillary, keeps the stable of battery case internal pressure; On the other hand, capillary can prevent that again electrolyte from directly adhering to the bigger gas outlet of bore, taken out of outside the battery box by the gas of effusion battery case, cause the transition volatilization of electrolyte, make the battery premature failure, simultaneously, the splashproof inner cap that in battery case, is provided with, can prevent that electrolyte is because of rocking or battery case tilts directly to adhere to the gas outlet or directly flows out from the gas outlet, be adapted to the adverse circumstances under colliery and other mine, prevent that electrolyte from flowing out the loss that causes personnel's equipment, can effectively prolong the useful life of battery.In sum, the utility model is simple and reasonable, and processing and manufacturing is easy, and the electrolyte stream vector is little, and long service life can realize suitability for industrialized production, is suitable for using in the colliery and the inferior adverse circumstances of mine, alternative existing mining lithium battery.
