Abstract
The utility model discloses a lead-acid battery. A single cell is arranged inside the lead-acid battery; an anode cylinder manifold and a cathode cylinder manifold are arranged in the single cell; an automatic temperature-sensing fluid infusion device is arranged at the anode cylinder manifold and the cathode cylinder manifold; the automatic temperature-sensing fluid infusion device comprises a hot shrinkage bag, a pressure limiting valve and electrolyte filled in the hot shrinkage bag; the pressure limiting valve is arranged at the bottom of the hot shrinkage bag and between the anode cylinder manifold and the cathode cylinder manifold. By the built-in automatic temperature-sensing fluid infusion device, under heating condition, the hot shrinkage bag shrinks and extrudes to release the electrolyte as the supplementation and to automatically judge the time of supplementing the electrolyte and the amount of the supplementation, thus effectively preventing the storage battery from thermal runaway, avoiding the deformation resulted from heating, automatically infusing the fluid for maintenance and prolonging the service life of the storage battery.
Description
Technical field
The utility model relates to a kind of lead acid accumulator.
Background technology
The side reaction that valve-control sealed lead acid battery in use has electrolyte produces, therefore the electrolyte in the storage battery can be fewer and feweri, impact the useful life to storage battery, the interior oxygen cycle ability of storage battery was strengthened after storage battery lost liquid, storage battery can produce thermal runaway phenomenon during work, make storage battery heating, distortion etc., cause storage battery to scrap.What of its liquid loss amount of judgement storage battery in use be difficult to, and can cause storage battery leakage, charge acceptance decline and battery tension to reduce bad reactions such as capacity reduction if mend electrolyte under the little situation of storage battery liquid loss amount.Thereby prior art is difficult to correctly to judge that storage battery could liquid feeding and liquid volume added that the maintenance of accumulators is made troubles, and has a strong impact on the useful life of lead acid accumulator.
The utility model content
The technical problems to be solved in the utility model provides a kind of lead acid accumulator, can judge accurately whether storage battery needs to replenish electrolyte, and in time replenish an amount of electrolyte.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this lead acid accumulator inside is provided with cell, be provided with positive bus and negative bus-bar in the described cell, described positive bus and negative bus-bar are provided with automatic temperature-controlled liquid supply device, described automatic temperature-controlled liquid supply device comprises pyrocondensation bag, pressure limiting valve and is potted in the interior electrolyte of pyrocondensation bag that pressure limiting valve is arranged on bottom the pyrocondensation bag and between positive bus and negative bus-bar.
The utility model adopts technique scheme, by built-in automatic temperature-controlled liquid supply device, the pyrocondensation bag shrinks to push and discharges electrolyte to replenish under heating condition, automatically when judgement adds electrolyte, and the amount of replenishing, thereby prevent that effectively storage battery generation thermal runaway phenomenon from taking place, and avoids the distortion that is caused by heating, automatic liquid supply safeguards, prolongs storage battery useful life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is a kind of lead acid accumulator structural representation of the utility model.
Embodiment
As shown in Figure 1, housing 7 inside of lead acid accumulator sealed package are provided with a plurality of cells, each cell has all comprised positive bus 1 and negative bus-bar 2, be provided with very big space between positive bus 1 and negative bus-bar 2 and the housing 7, on positive bus 1 and negative bus-bar 2, automatic temperature-controlled liquid supply device is installed, so automatic temperature-controlled liquid supply device is positioned at this interior volume, this automatic temperature-controlled liquid supply device comprises pyrocondensation bag 3, pressure limiting valve 4 and be potted in electrolyte 5 in the pyrocondensation bag 3, pressure limiting valve 4 are arranged on pyrocondensation bag 3 bottoms and between positive bus 1 and negative bus-bar 2.After storage battery uses the regular hour, its inner electrolyte reduces gradually, Wen Huidu rises gradually during battery-operated, this automatic temperature-controlled liquid supply device temperature is also raise, thermal contractible plastic can produce shrinkage phenomenon under heating condition, so can shrink when pyrocondensation bag 3 is heated, the high more amount of contraction of temperature is big more, the contraction build-up of pressure increases, when pressure reaches the opening pressure of pressure limiting valve 4, the pressure limiting valve 4 of automatic temperature-controlled liquid supply device is opened, the electrolyte 5 that the pyrocondensation bag is 3 li flows on the utmost point group 6, absorbed by battery separator and pole plate, the temperature of this moment just is the judgement temperature that automatic temperature-controlled liquid supply device is opened, and reaches opening temperature controlling by selected suitable material contracting with heat and appropriate pressure limiting valve opening pressure, therefore automatic temperature-controlled liquid supply device can automatic accurately judge whether storage battery needs to replenish electrolyte, and in time replenish an amount of electrolyte, reach the purpose of replenishing electrolyte, thereby prevent that effectively storage battery generation thermal runaway phenomenon from taking place.
