Abstract
A kind of positive grid increased the service life, including upper side frame, lower frame, left frame, left frame and horizontal bar, perpendicular muscle, upper side frame top is provided with plate ear, and the gauge of described positive grid successively decreases to lower frame from upper side frame.This utility model is according to the analysis of grid corrosion state positive to dead battery, devise the positive grid that a kind of slab lattice thickness is gradual change, this structure breaks the design concept that existing grid integral thickness is consistent, propose the technical scheme of slab lattice thickness gradual change from top to bottom, while reasonable utilization material, effectively solve to annoying the battery failure problem that accumulator producer causes due to positive grid corrosion the most always, improve service lifetime of accumulator.
Description
Technical field
This utility model relates to a kind of accumulator part, the positive grid that particularly can increase the service life, and belongs to accumulator skill
Art field.
Background technology
Grid is the strength member of accumulator, and on the one hand its effect is the carrier of active substance, plays skeletal support and glues
The effect of attached active substance；On the other hand the conductor as electric current plays a part afflux, confluxes and defeated stream；Grid also conduct
The current-sharing of pole plate plays and makes balanced current distribution act in active substance.Battery grid many employings lead antimony, lead-calcium alloy material
Material, is drawn in the net by gravity casting, pressure zone and the method such as pressure zone punching molding is made.The failure cause of lead-acid accumulator is more
The corrosion of positive grid, this is that therefore its main component facial pallor is easy owing to positive grid is always under higher electrode potential effect
Oxidized corrosion is lead oxide, and the increase of discharge and recharge number of times during using along with accumulator, positive grid corrosion is more and more thinner, very
To fracture, ultimately result in battery failure.Usual accumulator producer extends positive plate by the method increasing positive slab lattice thickness and supports
The erosion-resisting time, thus increase the service life, but positive plate thickness increase adds inventory charge amount undoubtedly, improves
Product cost.Therefore, grid structure reasonable in design is ten for the battery failure solving to cause due to the fracture of positive grid corrosion
Divide important.
Utility model content
The purpose of this utility model is to provide a kind of position being susceptible to corrosion failure according to positive plate, appropriate design
The positive grid increased the service life of positive grid structure.
Problem described in the utility model solves with following technical proposals:
A kind of positive grid increased the service life, including upper side frame, lower frame, left frame, left frame and horizontal bar, erects
Muscle, upper side frame top is provided with plate ear, and the gauge of described positive grid successively decreases to lower frame from upper side frame.
The above-mentioned positive grid increased the service life, the gauge of described positive grid upper side frame is d1, and positive grid is following
The gauge of frame be d2, d1/d2 be 1.4～2.3.
The above-mentioned positive grid increased the service life, described positive grid upper side frame gauge is 1-5 millimeter.
This utility model is according to the analysis of grid corrosion state positive to dead battery, and devising a kind of slab lattice thickness is gradual change
Positive grid, this structure can effectively solve the battery premature failure caused due to positive grid corrosion, and conservative control produces again
Product cost, has the feasibility of batch popularization and application.This utility model breaks the design concept that existing grid integral thickness is consistent,
Propose the technical scheme of slab lattice thickness gradual change from top to bottom, while reasonable utilization material, effectively solve the most always
Annoying the battery failure problem that accumulator producer causes due to positive grid corrosion, improve service lifetime of accumulator.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A sectional view (amplification) of Fig. 1.
In figure, each list of reference numerals is: 1, upper side frame, 2, plate ear, 3, horizontal bar, 4, perpendicular muscle, 5, left frame, 6, lower frame, 7, left
Frame.
Detailed description of the invention
Referring to Fig. 1, Fig. 2, this utility model includes upper side frame 1, lower frame 6, left frame 7, left frame 5, upper and lower, left,
Being provided with horizontal bar 3 and perpendicular muscle 4 in the rectangle frame that left frame surrounds, on top the top of frame is provided with plate ear 2.This utility model is by solving
Cuing open substantial amounts of life test and return to battery discovery, owing to positive grid corrosion causes the battery of battery failure, corrosion location is main
Concentrating on the middle and upper part of positive grid, the closer to plate ear, grid corrosion is the most serious, it is therefore proposed that solution below: positive grid
Gauge successively decrease to lower frame from upper side frame.The battery mistake that positive grid middle and upper part corrosion fracture causes is solved by this design
Effect, the most rationally suitable material, control accumulator cost.
Referring to Fig. 2, the physical dimension of positive slab lattice thickness is as follows: the gauge of upper side frame is d1, positive grid lower frame
Gauge be d2, d1/d2 be 1.4～2.3；Upper side frame gauge is 1-5 millimeter.The concrete size of positive grid is according to electric power storage
Depending on the purposes in pond and capacity, generally industrial battery is relatively thick with positive slab lattice thickness, the positive plate of automobile starting battery
Grid thickness is relatively thin.
