Abstract
The utility model discloses a polar plate grid of a lead acid storage battery, and is used for effectively solving the problems that the existing grid is high in internal resistance and low in lead plaster utilization rate. The polar plate grid of the lead acid storage battery comprises a rectangular electrode frame enclosed by four frame ribs, vertical and transverse rib strips which are staggered with each other to form a netlike structure, and a polar lug which is arranged at the top part of the electrode frame, wherein an oblique rib strip is arranged between the lower left corner of the electrode frame and the center of the electrode frame and between the lower right corner and the center of the electrode frame respectively. The polar plate grid has the advantages as follows: the two oblique rib strips enhance the strength of the plate grid and ensure that the total conductive cross-sectional area of the vertical rib strips is increased by 50%, the internal resistance of an alloy of the plate grid is reduced, the high-current discharge performance of the battery is improved, the utilization rate of the lead plaster on the surface of the plate grid is improved when the storage battery discharges, and the capacity and consistency of the battery are promoted, so that the plate grid is an ideal plate grid for power batteries.
Description
Technical field
The utility model relates to a kind of lead-acid accumulator grid.
Background technology
At present, it is many that the lead-acid accumulator grid structure has a horizontal bar, the perpendicular few characteristics of rib, the grid structure that is rectangle, it is insufficient that the surface is coated with the cream electrochemical reaction when discharging and recharging, when battery discharge, because perpendicular rib is few, total conductive area is little, increase the internal resistance of cell, make the lead plaster utilance extremely low, electric current flows to active material by perpendicular rib during charging, pull the gate rib interface and form corrosion, perpendicular rib ruptures easily, increases the pole plate internal resistance, makes the energy content of battery not give full play to, be easy to generate the softening phenomenon of cream and lead plaster, follow the generation of premature capacity loss simultaneously.Directly influenced the expected service life of battery.
The utility model content
The purpose of this utility model is to provide a kind of lead-acid accumulator grid, can effectively solve the problem that existing grid internal resistance is big, the lead plaster utilance is low.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of lead-acid accumulator grid, comprise in the rectangle grid frame that surrounded by four frame muscle, the frame lug that is staggered to form cancellated perpendicular rib and transverse rod strip, is arranged on the grid arch, between the lower left corner of described grid frame to the center of grid frame, be equipped with a diagonal bar bar between the lower right corner to the center of grid frame of grid frame.
Preferably, comprise that also the reinforcement horizontal bar at connection grid frame two a vertical edges middle part is connected the perpendicular muscle of reinforcement at grid frame two horizontal sides middle part with one; Further strengthen bulk strength, improve perpendicular muscle conductive area.
Preferably, described reinforcement horizontal bar erects the center that muscle intersects at the grid frame with reinforcement, and the upper end of described two diagonal bar bars all links to each other with reinforcement horizontal bar and the perpendicular muscle junction of reinforcement; Reduce internal resistance and strengthen grid frame intensity.
Preferably, the cross section of the horizontal edge of described reinforcement horizontal bar, transverse rod strip and grid frame is rhombus; The cross section that the vertical edge of muscle, perpendicular rib and grid frame is erected in described reinforcement is rhombus; Increase conductive area.
Compared with prior art, the utility model has the advantages that: by increasing by two diagonal bar bars, strengthen the intensity of grid, make perpendicular rib always conduct electricity cross-sectional area simultaneously and increase 50%, reduce the grid alloy internal resistance, improved the high-rate battery discharge performance, when battery discharging, improved the utilance of grid surface lead plaster, promoting battery capacity and consistency, is the desirable grid of motive-power battery.

Embodiment
Consult Fig. 1 and be the embodiment of a kind of lead-acid accumulator grid of the utility model, a kind of lead-acid accumulator grid, comprise the rectangle grid frame 2 that is surrounded by four frame muscle, be staggered to form cancellated perpendicular rib 3 and transverse rod strip 4 in the frame, be arranged on the lug 1 at grid frame 2 tops, between the lower left corner of described grid frame 2 to the center of grid frame 2, be equipped with a diagonal bar bar 5 between the lower right corner of grid frame 2 to the center of grid frame 2, comprise that also the reinforcement horizontal bar 6 at 2 liang of vertical edges middle parts of a connection grid frame is connected the perpendicular muscle 7 of reinforcement at 2 liang of horizontal sides middle parts of grid frame with one, described reinforcement horizontal bar 6 erects the center that muscle 7 intersects at grid frame 2 with reinforcement, and the upper end of described two diagonal bar bars 5 all links to each other with reinforcement horizontal bar 6 and perpendicular muscle 7 junctions of reinforcement.
As shown in Figure 2, the cross section of the horizontal edge of described reinforcement horizontal bar 6, transverse rod strip 4 and grid frame 2 is rhombus.
As shown in Figure 3, the cross section of the vertical edge of the perpendicular muscle 7 of described reinforcement, perpendicular rib 3 and grid frame 2 is rhombus.
Each rib can adopt no cadmium alloy, environment-friendly high-efficiency, and the cross-sectional area of strengthening horizontal bar and the perpendicular muscle of reinforcement is greater than the cross-sectional area of perpendicular rib and transverse rod strip.Perpendicular rib 3 by increasing perpendicular rib 3, reduces the pole plate internal resistance as the conducting electric current, promotes battery large current charge receiving ability, has improved the high-rate battery discharge performance simultaneously.Transverse rod strip 4 is for supporting the effect of active material, promote the mechanical strength of pulling grid by the size of strengthening horizontal bar 6 in the middle of improving, grid uses lead-calcium-tin alloy, reduces the grid height, pulling grid framework two perpendicular rib 3 spacings is 6-11mm, and two transverse rod strips, 4 spacings are 14-16mm.Pull grid middle part transverse stiffener rib and vertical stiffener rib junction, setting up two tiltedly perpendicular muscle.This rib can be avoided sulfation occurring because the pole plate excessive height causes the pole plate bottom, promotes the conductive capability of bottom, makes pole plate generation electrochemical reaction more even, makes the performance of battery more reliable and more stable.
The above only is specific embodiment of the utility model, but technical characterictic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
