Abstract
The utility model provides a lead-acid storage battery grid which is improved as follows: the distance between longitudinal and horizontal ribs is respectively changed from small to large along with the condition that the distance from the longitudinal and horizontal ribs to a pole lug is changed from large to small, and the sectional area of the same longitudinal rib close to the pole lug gradually is changed from large to small. Due to the reasonable distribution of the ribs, the ribs adapt to the current trend after being made into a pole plate, active substances are uniform in formation, the utilization ratio of the active substances is increased, and the service life of the pole plate is prolonged.
Description
Technical field
The utility model relates to a kind of grid that is applicable to lead acid accumulator, belongs to the lead acid accumulator field.
Background technology
Grid is the important component part of lead accumulator, plays and supports active material, serves as the carrier of active material, the effect of conduction current, makes balanced current distribution on active material.Grid structure mainly comprises frame, lug, transverse rod strip and vertical rib strip.In current existing grid structure, the transverse and longitudinal rib all adopts even arrangement mode.Actual proof, it is inhomogeneous that this mode easily causes the inner active material of pole plate to change into, general near Pb0 in the active material at lug position
2content can reach 70%～80%, and away from Pb0 in the active material at lug position
2content only can reach 50～70%.The long-term use, the active material at each position of pole plate lost efficacy because different utilances makes pole plate.
The utility model content
The purpose of this utility model is to overcome the weak point of existing grid, provides a kind of inner active material of pole plate that can make to change into evenly, improves pole plate serviceability and the lead acid accumulator plate grid in life-span.
The technical solution of the utility model is: a kind of lead acid accumulator plate grid, by vertical rib strip, transverse rod strip, frame and lug, formed, its improvements are ascending along with longitudinal and transverse rib and lug distance, longitudinal and transverse rib spacing is descending respectively, and same sectional area of the vertical rib strip of close lug is descending.
Further scheme is: along with the increase of longitudinal and transverse rib and lug distance, the vertical rib strip spacing is decreased to 8～9mm by 10～11mm, and the transverse rod strip spacing is decreased to 9～10mm by 13～14mm; Same width of 3～5 vertical rib strips of close lug, along with the increasing with the lug distance, is decreased to 1.5～2mm by 2.5～4mm, and thickness is constant; The transverse frame be connected with lug is 4～5mm near the width at lug place, away from the width at lug place, is 3～4mm.
The structure that the utility model is spacing and cross section reasonable change by longitudinal and transverse rib in grid by existing structural change of evenly arranging, adapt to current trend, and active material in pole plate is changed into evenly, improves active material utilization, extends the pole plate life-span.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model is made pole plate and changed into rear detection position distribution schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, further illustrate the utility model.
Grid shown in Fig. 1, for making the 12V lead acid accumulator, is of a size of vertical rib strip spacing, transverse rod strip spacing, vertical rib strip width and the transverse frame change width scope be connected with lug shown in figure.
In the present embodiment, along with the distance of vertical rib strip A and lug C is ascending, the vertical rib strip spacing is decreased to 8mm by 10mm, and along with the distance of transverse rod strip B and lug C is ascending, the transverse rod strip spacing is decreased to 9mm by 13mm; Ascending near three vertical rib strips of lug along with the lug distance, each root be decreased to 1.5mm by 3mm, and thickness is constant, all the other eight vertical rib strip width and thickness are all constant; The transverse frame D be connected with lug is 4mm near the width at lug place, away from the width at lug place, is 3mm, and thickness is constant; All transverse rod strips and its excess-three bar border width and thickness are all constant.
After this grid is made to pole plate and changing into, the active material of getting different parts list lattice carries out Pb0
2content detection, in Fig. 2,1～15 represents that 15 are detected position, testing result (mass percent) is as follows:
Pb0 according to the sampling of pole plate different parts
2the content detection situation, can obviously find out, each position Pb0
2be evenly distributed, upper and lower content is no more than 2 percentage points, efficiently solves existing grid because of the inner rib unreasonable active material problem of non-uniform caused of arranging.
Claims (4)
