Description
Technical field
The utility model relates to a kind of grid structure of lead acid accumulator.Be particularly useful for high-multiplying power discharge grid structure.
Background technology
For low range discharge lead acid accumulator, discharging current is less, and in the various factors of the voltage drop that causes when constituting lead acid accumulator internal resistance and discharge, grid occupies a secondary and subordinate position.So what most producers adopted in the actual production is that rectangular grid grid or perpendicular rib are the radial grid of individual layer of oblique line.
But for the high-multiplying power discharge lead acid accumulator, discharging current is very big, thereby the capacity of battery and life-span are often depended on the design and the manufacturing process of pole plate.Because the conductive capability of active material is relatively poor in the pole plate, the main backup plate grid of the conduction of pole plate realize, thereby the design of the grid particular importance that just seems.
Generally there is following shortcoming for traditional grid design:
1, for traditional rectangle grid, electric current distribution is inhomogeneous during discharge, and internal resistance is bigger, and the pressure drop of pole plate is bigger, thereby is difficult to satisfy the needs of heavy-current discharge.
2, for individual layer radioactivity grid, the single lattice area in bottom is bigger, and grid is relatively poor to the hold facility of active material, and lead plaster breaks away from easily, thereby reduces the useful life of lead acid accumulator.
Summary of the invention
At above-mentioned present situation, the utility model provides a kind of grid structure of high-multiplying power discharge lead acid accumulator; This grid when the lead acid accumulator high-multiplying power discharge on the pole plate current density distributing homogeneity higher, pole plate internal resistance minimizing, pressure drop reduce, thereby increase the discharge performance of battery.And this kind grid structure strengthens the hold facility of active material, can prevent the disengaging of lead plaster, thereby reach the purpose in the useful life that increases lead acid accumulator.
The technical solution of the utility model is achieved in that lead acid accumulator plate grid, comprise the grid frame, be located in the grid frame and the net grid that are connected with the grid frame and be located at lug on the grid frame, the net grid that are connected with the grid frame are made up of 2-4 unit, each unit includes vertical conduction rib and cross-brace rib radially, be provided with respectively the crossbeam that confluxes that the conduction rib with adjacent cells electrically connects between adjacent Unit two, and conflux crossbeam and grid frame electrically connect.
It is radiant that the extended line of the utility model conduction rib radially compiles same point.
The utility model lug is located at grid frame upper end, radiant can be positioned at grid frame top more arbitrarily (be the lug place horizontal grid frame top more arbitrarily).
The utility model is by the improvement to the grid structural design, adopt the conduction rib design of radiation, make this grid when the lead acid accumulator high-multiplying power discharge on the pole plate current density distributing homogeneity higher, pole plate internal resistance minimizing, pressure drop reduce, thereby increase the discharge performance of battery.And this kind grid structure strengthens the hold facility of active material, can prevent the disengaging of lead plaster, thereby reach the purpose in the useful life that increases lead acid accumulator.

Embodiment
Referring to Fig. 1, the utility model comprises grid frame 7, be located in the grid frame 7 and net grid that are connected with grid frame 7 and be located at lug 1 on the grid frame 7, the net grid that are connected with grid frame 7 are made up of 2-4 unit, each unit includes vertical conduction rib 8 and cross-brace rib 9 radially, be provided with respectively the crossbeam 5,6 that confluxes that the conduction rib with adjacent cells electrically connects between adjacent Unit two, and conflux crossbeam and grid frame electrically connect.
Accompanying drawing 1-4 has provided the embodiment that the net grid are made up of 3 unit, and the utility model adopts the syllogic conduction rib design radially of top grid section 2, middle part grid section 3, bottom grid section 4.Three segment length are between 1/3, two section of whole grid length all that the mode with the crossbeam that confluxes connects, and every section grid design shape is all identical, and the horizontal grid frame top 1: 10 that is with the lug place is that radiant carries out radiation (referring to Fig. 2-4).Whole grid is as a whole, can use the lead alloy casting of fusing to form by the casting machine of special use.
The radiant 10 of the conduction rib radially of each unit of the utility model is above the horizontal grid frame at lug place.Or the extended line of conduction rib radially to compile same point be radiant 10.Radiant can be positioned at any point of the horizontal grid frame top at lug place.
The utlity model has following advantage:
1, in the utility model grid radially the radiant of conduction rib above the horizontal grid frame at lug place, during the lead-acid accumulator high-multiplying power discharge on the pole plate everywhere electric current can directly be flowed to lug, or by behind the crossbeam that confluxes between two sections again by being flowed to lug at the conduction rib of front unit or along the grid frame, the electric current distribution uniformity improves, pole plate internal resistance minimizing, pressure drop reduce, thereby increase the discharge performance of battery.
2, single lattice area is more even in the utility model grid structure, the single lattice of electrodeless large tracts of land, thereby this kind grid structure strengthens the hold facility of active material, can prevent the disengaging of lead plaster, thereby reach the purpose in the service life that increases lead-acid accumulator.
