Abstract
The positive grid of a kind of traction accumulator, comprise positive grid, positive grid is made up of positive grid rib and comb, positive grid rib is positioned at the centre position of comb, positive grid rib is provided with overlap, positive grid rib is fixed on the centre position of comb by overlap, the height of overlap is higher than positive grid rib height, positive grid rib and comb contact site adopt arc-shaped convex structure, arc-shaped convex structure adopts and equidistantly distributes, positive grid rib top is provided with crossbeam, crossbeam centre position is provided with lug, the shape of positive grid rib is oval, by adopting the content ratio of the positive grid of the many alloy die casts of plumbous antimony arsenical copper and control arsenical copper, decay resistance and the casting character of positive grid can be promoted, positive grid rib can be allowed to be fixed in the middle of comb by the setting of overlap, the decay resistance of positive grid is promoted.
Description
Technical field
The utility model relates to a kind of grid, is specifically related to the positive grid of a kind of traction accumulator.
Background technology
The application of storage battery is very extensive, some storage batterys are used as accessory power supply, also the storage battery had is used as stand-by power supply, existing lead acid accumulator, no matter its purposes how, its primary structure is made up of following a few part substantially, according to the difference that electric current and voltage requires, be made up of some series-parallel monomers, each monomer is by housing, in housing just, negative plate, just, barrier film between negative plate and the electrolyte in housing are formed, the grid of common lead acid accumulator adopts gravitational casting to form usually, the coarse grains of composition grid, grid is not corrosion-resistant, traction battery uses mainly as the electrical source of power of electri forklift, occupation mode is for recycling, and frequent deep discharge, for grid decay resistance and require high with active material binding ability, therefore it usually uses plumbous antimony multicomponent alloy grid and adopts die-casting technique to obtain excellent decay resistance.
Summary of the invention
The purpose of this utility model is to provide a kind of corrosion-resistant, the positive grid of a kind of traction accumulator of good seal performance.
The technical solution of the utility model is: the positive grid of a kind of traction accumulator, comprise positive grid, described positive grid is made up of positive grid rib and comb, described positive grid rib is positioned at the centre position of comb, described positive grid rib is provided with overlap, positive grid rib is fixed on the centre position of comb by described overlap, described overlap adopts convex architecture, the height of described overlap is higher than positive grid rib height, centre distance between two described overlaps is equal, described positive grid rib and comb contact site adopt arc-shaped convex structure, described arc-shaped convex structure adopts and equidistantly distributes, described positive grid rib top is provided with crossbeam, described crossbeam adopts T-shaped structure, the height at described crossbeam two ends is shorter, height in the middle of described crossbeam is higher, described crossbeam centre position is provided with lug, the shape of described positive grid rib is oval.
The angle of described overlap circular arc is between 30 ° ~ 90 °, and the difference in height between described overlap and positive grid rib is between 1.5mm-2.1mm, and the centre-to-centre spacing between two described overlaps is between 8mm-12mm.
Spacing between described arc-shaped convex structure is between 8mm-9mm, and the number of described arc-shaped convex structure is 4-6.
The diameter of described positive grid rib is between 2.5mm-3.5mm, and the top of described positive grid rib is provided with change tapering cross section, and the distance in described change tapering cross section is between 85mm-95mm.
Described positive grid is that die casting forms, and described positive grid adopts the many alloy die casts of plumbous antimony arsenical copper to form, and the ratio of the content of described arsenical copper element is 2: 1.
Advantage of the present utility model is: by adopting the content ratio of the positive grid of the many alloy die casts of plumbous antimony arsenical copper and control arsenical copper, decay resistance and the casting character of positive grid can be promoted, positive grid rib can be allowed to be fixed in the middle of comb by the setting of overlap, the decay resistance of positive grid is promoted, arc-shaped convex structure is adopted between positive grid rib and comb contact site, the effect sealing anti-leak-stopping powder can be played, lug is arranged on the centre position of crossbeam, play the effect collecting electric current, crossbeam is set to T-shaped structure, the effect of confluxing that can improve positive grid can save material simultaneously, play the effect reduced costs.
