Description

A kind of grid of storage battery

Technical field

Battery technology field is the utility model is related to, more particularly to a kind of grid of storage battery.

Background technology

The grid of storage battery is typically to be made of frame 1, lug 2, the transverse rod strip 3 of some even thickness and vertical bars bar 4, such as Fig. 1, lug 2 are located at the one side edge of frame 1, intersect between each transverse rod strip 3 and each vertical bars bar 4 and be arranged on the interior of frame 1 Side, be parallel to each other between each transverse rod strip 3 spaced set, and be parallel to each other spaced set between each vertical bars bar 4, afterwards with The frame 1 of transverse rod strip 3 and vertical bars bar 4, which simultaneously applies, to be spread after lead plaster up to the pole plate of storage battery.During the work time, in lead plaster Electrons are moved in each transverse rod strip and each vertical bars bar, then are moved up along each vertical bars bar and be finally pooled to lug position, so The one end of the vertical bars bar and transverse rod strip one end electric current relative distance nearer apart from lug farther out is with regard to larger, and by transverse rod strip and vertical bars Bar each several part even thickness, so each several part resistance is essentially identical（In the case of only considering material area）, so result in away from The vertical bars bar and transverse rod strip one terminal voltage nearer from lug is larger, and then causes the active matter in lead plaster of the lug compared with near-end position Matter utilization rate is higher, and active material can discharge the corrosive substances such as sulfuric acid at work, easily corrodes vertical bars bar and transverse rod strip, In practical applications, often the nearer vertical bars bar of appearance distance lug and transverse rod strip end have been corroded fracture, and apart from pole Ear vertical bars bar farther out and transverse rod strip are also excellent, and for whole grid each several part using uneven, service life is shorter, causes resource Waste.

Utility model content

Purpose of utility model：For problems of the prior art, the utility model provides a kind of grid of storage battery, The utilization rate of electronics that can be on active balance grid in each several part lead plaster in active material, effectively extends the grid service life.

Technical solution：The utility model provides a kind of grid of storage battery, including frame, lug, it is some mutually The vertical bars bar of the transverse rod strip for the even thickness that is arranged in parallel and some even thickness arranged in parallel, the lug are located at institute Frame one side edge is stated, each transverse rod strip is mutually perpendicular to cross-conduction with each vertical bars bar and is arranged on the scuncheon, It is characterized in that, at least a main vertical bars bar is located along the same line with the lug in some vertical bars bars, remaining is each Vertical bars bar is arranged to both sides successively using the main vertical bars bar as baseline；The transverse rod strip of every vertical bars bar both sides shifts to install, and from Close to the direction away from the lug, the spacing between the transverse rod strip is sequentially reduced two-by-two, and the width of each transverse rod strip Degree is sequentially reduced.

Preferably, in the main vertical bars bar both sides, from close to the direction away from the main vertical bars bar, vertical bars two-by-two Spacing between bar is sequentially reduced.

Preferably, in the main vertical bars bar both sides, from close to the direction away from the main vertical bars bar, each vertical bars bar Width be sequentially reduced.

Beneficial effect：In the utility model, first, from by one end proximad away from the lug, two-by-two between transverse rod strip Spacing be gradually reduced；From close to away from the main vertical bars bar direction, two-by-two the spacing between the vertical bars bar subtract successively It is small；In this way, after smearing lead plaster on grid, one end away from lug, the square being made of each transverse rod strip and each vertical bars bar just compared with Small, the electronics in less square in lead plaster in active material can be moved on each transverse rod strip and each vertical bars bar quickly（Cause It is smaller for square, so moving displacement is smaller）, then electronics moved along each rib on main vertical bars bar（Because air line distance is most short, Electronics also can the shortest route of chosen distance be moved to destination --- on lug）, and then lug position is moved again to by lug Utilize；And grid one end nearer apart from lug, each transverse rod strip and the square that each vertical bars bar forms are just larger, in larger square Electronics in lead plaster in active material is moved to institute on each transverse rod strip and each vertical bars bar for the electronics in compared with blockage The time needed is longer（Because square is larger, moving displacement is larger）, so the utility model is equivalent to balancing distance Lug nearer end and the utilization rate compared with electronics in active material on distal plate grid；

Secondly, the utility model is gradually reduced from by the direction proximad away from main vertical bars bar, the width of each vertical bars bar；From by Proximad one end away from lug, the width of each transverse rod strip are gradually reduced；The vertical bars bar and transverse rod strip resistance of wider width are smaller（Only In the case of considering material area）, in the case where electric current is equal, the voltage on the vertical bars bar and transverse rod strip of wider width is opposite Smaller, this makes it possible to the utilization rate of relative reduction active material in the lead plaster of lug position, is lifted away from lug position Lead plaster in active material utilization rate so that reaching balanced utilizes the mesh of each several part vertical bars bar and transverse rod strip on whole grid , the service life of whole grid is lifted, economize on resources the energy；

Again, each transverse rod strip of the both sides of each vertical bars bar shifts to install in the utility model, so each transverse rod strip and vertical bars Conductive channel between bar be distributed in whole frame it is relatively uniform, it is more uniform equivalent to electronics overall distribution on grid.

For grid of the prior art, electronics in each several part active material on the grid in the utility model Utilization rate relative equilibrium, effectively avoids transverse rod strip and vertical bars bar apart from lug nearer end since the active material of this part utilizes Rate is larger and the fracture that is corroded, and effectively lifts the service life of grid.
