Device of air and positive and negative terminals composition, each single lattice voltage rating is 2V, the voltage rating 2*nV of battery (n=1,2,
3....).Due to there is multiple single batteries, lead-acid accumulator can not be made identical there are error in production process and exist
Difference, such as the pole plate weight of each single battery, thickness, vallecular cavity size, acid adding amount, assembling pressure and charge and discharge process heat dissipation
The difference of degree etc. will result in generation amount of gas difference and pressure difference between single battery, and lead-acid accumulator can be because individual
Single battery internal pressure excessive deformation, in addition because individual secure valve not valve opening failure caused by whole battery scrap.The prior art
With following shortcoming:
1. present each single lattice of battery is all individual row stomata, independent safety valve, air pressure is inconsistent in each single lattice, be easy because
Single lattice is backward and whole battery is caused to scrap.
2. the gas vent of present battery all on battery cover, if having acid liquor overflow in battery, easily corrodes terminal, even
Cause battery short circuit.
3. existing battery is all by gas vent acid adding, gas vent is generally all smaller, and acid adding is slower, in production process also not
The acid amount being easy in each single lattice of detection.
For this reason, it may be necessary to provide a kind of improved lead-acid accumulator, solve the problems, such as above.
Utility model content
The purpose of this utility model is to provide a kind of improved lead-acid accumulators, acid adding, row with special designing
Depressed structure, and can solve between cell negative terminal that air pressure is unbalanced, single lattice is overflow acid corrosion terminal or battery short circuit problem.
To reach the purpose, the utility model is provided the following technical solutions:
Improved lead-acid accumulator comprising battery case, battery cover, battery terminal and multiple single batteries, the electricity
Acid adding hole is provided at the top of Chi Gai, it is characterised in that: be provided with gas vent and the multiple monomer electricity in the side of the battery cover
Pond shares the gas vent, and safety valve is arranged in the gas vent, and the multiple single battery shares the safety valve.
Preferably, for big mouth, unlimited, sunk type hole, multiple acid adding hole lower parts pass through sunk type vallecular cavity in the acid adding hole
Connection.
Preferably, the battery cover is equipped with cover board mounting recess, and the acid adding hole is respectively positioned on the cover board mounting recess
In, the cover board of adaptation is stamped on the cover board mounting recess.
Preferably, seal groove is set on the battery cover, and all acid adding holes are described close in the seal groove
Sealing groove and the acid adding hole are respectively positioned in the cover board mounting recess；It is equipped at the back of the cover board and is adapted to the seal groove
Sealing strip, the cover plate lid is adapted to the sealing strip in the cover board mounting recess, the seal groove and passes through sealing material
Material is tightly connected.
Preferably, the battery terminal is arranged in except the cover board mounting recess of the battery cover and battery terminal
Top be higher than the cover board.
The technical solution of the utility model produces following technical effect: 1, acid adding hole is separated with gas vent, and acid adding is more held
Easily, quickly, and convenient for liquid level visualization in battery when charging；2, all single batteries are connected in outside, and common safety valve exhaust makes
Whole inside battery air pressure it is consistent；3, gas vent is in battery cap lateral, far from acid adding hole, it is ensured that without acid liquor overflow in battery.
In addition, the preferred embodiment of the utility model also generates following effect: acid adding is easier more rapidly, it is not easy to be run acid and be gone out
Come, terminal corrosion or battery short circuit will not be caused.
Detailed description of the invention
Fig. 1 is the schematic diagram of one embodiment of the battery cover of the improved lead-acid accumulator of the utility model.
Fig. 2 is the overall schematic of one embodiment of the improved lead-acid accumulator of the utility model.
Specific embodiment
The optimal technical scheme of the utility model is discussed in detail below in conjunction with attached drawing.
As shown in Figure 1 and Figure 2, which includes battery case 20, battery cover 10, battery terminal and more
A single battery, these single batteries are placed on inside battery case 20, this is the prior art, seldom tired to state.
The top of battery cover 10 is provided with acid adding hole 12, shares 6 acid adding holes 12 in the present embodiment.These acid adding holes 12 are equal
There is big mouth to open wide, sunk type hole, that is, is seen as stepped hole wide at the top and narrow at the bottom from cross section, and these acid adding holes (stepped hole)
Lower part is connected to by sunk type vallecular cavity, and is finally connected in battery case 20.The acid adding hole of this design is more convenient acid adding, speed
Degree faster, even if acid adding amount greatly be not easy to diffuse out and.
Preferably, seal groove 111 is additionally provided on battery cover, which is to wrap all six acid adding holes 12
The recess portion of strip seal groove that is, strip including including.
Preferably, it is also set up on battery cover at cover board mounting recess 11 (edge 110), above-mentioned acid adding hole 12 and seal groove
111 are respectively positioned in cover board mounting recess 11, and after adding acid, cover board 15 is covered and (be provided with) above cover board mounting recess 11.
Sealing strip that correspondingly, the back setting of cover board 15 be adapted to above-mentioned seal groove 111 (and strip is raised, schemes
In be not shown), cover board 15 is covered in cover board mounting recess 11, sealing strip adapts in seal groove 111, seal groove 111 and lid
Sealing strip on plate 15 is sealed by sealing materials such as epoxy resin sealants, and cover board 15 is also salable to fit in cover board company
It connects in recess portion 11.
Preferably, it opens in the side of battery cover 10 there are two gas vent 13 and multiple single batteries shares gas vent 13,
Safety valve 61, multiple single battery common safety valves 61 are set in gas vent 13.Certainly, in the embodiments of the present invention,
One or three or more gas vent can also be opened.The acid solution that gas vent may be run out of in this way is unable to corrosion cell terminal, and
And air pressure is consistent in each single battery.
Battery terminal 14 is arranged in except the cover board mounting recess 11 of battery cover 10 and its top is higher than cover board 15, this
Sample, the acid liquid corrosion that battery terminal 14 just may unlikely be run out of.
The lead-acid accumulator of above structure, independent due to being separated using gas vent and acid adding hole, acid adding is very fast when production, raw
The acid amount being also easy in each single battery of detection during producing, improves production efficiency, guarantees battery quality.Moreover, because it is adopted
With each single battery common safety valve, it is ensured that air pressure is consistent in each single battery of the lead-acid accumulator, each single battery performance
Consistency is higher, extends battery.Furthermore since gas vent is opened in the side of battery cover by it, avoid sour in battery
Hydrorrhea goes out to corrode terminal or battery short circuit risk.
The above description is that the preferred embodiments of the utility model, cannot limit the guarantor of the utility model with this certainly
Protect range.Any equivalent replacement and transformation for technical solutions of the utility model, it is all within the protection scope of the present utility model.
