Abstract
The utility model discloses a kind of battery positive voltage grid, comprises lug (1), and the bottom of described lug (1) is provided with multiple lengthways of rod (2), and described lengthways of rod (2) is circular, and described lengthways of rod (2) circumferencial direction is provided with 4 projections (3).The utility model has the advantages that: the lengthways of rod of grid is large, and conductive section is large, and make electrical conductivity hinge structure more unimpeded, catchment effect is good; Storage battery is corrosion-resistant, high temperature resistant, and the life-span is long, and normal service life can reach 8 years.
Description
Technical field
The utility model relates to a kind of storage battery, particularly a kind of battery positive voltage screen.
Background technology
Storage battery is widely used in industry, agriculture every field, and storage battery is in charge and discharge process, and the conduction of the electron exchange of pole plate active principle is mainly realized by screen.Anode plate grid general is at present made up of lug, frame and grid, according to the difference of grid, by being divided into rectangle grid, radioactivity grid and the stretch grid.Positive pole rectangle grid and positive pole radioactivity grid due to resistance large, catchment effect is poor, causes high-rate battery discharge, and the electric properties such as cryogenic property are all poor, more easily be corroded compared with the negative electrode grid of their phase combos, the useful life of storage battery is reduced greatly; And although the stretch grid catchment effect is good, its production must rely on special equipment, and cost is higher.
Summary of the invention
The defects such as it is large that existing grid anode plate grid exists resistance, catchment effect difference, this defect cause high-rate battery discharge and cryogenic property electric property poor.Existing grid anode plate grid is all adopt normal pressure casting, and grid inner air is many, forms a lot of pore, easily enters sulfuric acid, and corrode during battery uses in these pores.Dissect the anode plate grid of dead battery, find that the lengthways of rod of anode plate grid is normal, and corrosion and fracture obviously occur horizontal rib, the corrosion of horizontal rib and fracture cause whole battery failure.Because the horizontal rib of anode plate grid is easily corroded, the useful life of storage battery is significantly reduced, generally can only use 3 years.
The technical problems to be solved in the utility model is to provide one, and to meet catchment effect good, heavy-current discharge and cryogenic property electric property good, again can slowing down corrosion, the battery positive voltage grid that increases the service life.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of battery positive voltage grid, comprises lug, and the bottom of described lug is provided with multiple lengthways of rod.
The further technical scheme of the utility model is: described lengthways of rod shape of cross section is non-square.
The further technical scheme of the utility model is: described lengthways of rod shape of cross section is for circular.
The further technical scheme of the utility model is: described lengthways of rod circumferencial direction is provided with multiple projection.
The further technical scheme of the utility model is: described projection is 4.
The utility model compared with prior art, there is following features: the lengthways of rod cross section of the utility model grid is preferably circular, be conducive to adopting compression molding process, conveniently comb is installed, lengthways of rod and lug connecting portion are preferably up big and down small taper shape, be circumferentially with projection at lengthways of rod, the effect of fine flat fixed calandria can be played.
The lengthways of rod of the utility model grid is large compared with the lengthways of rod of existing grid, and conductive section is large, and make electrical conductivity hinge structure more unimpeded, catchment effect is good.Anode plate grid adopts extrusion process one-shot forming simultaneously, extrusion process can make the dense structure of anode plate grid, Stability Analysis of Structures, and grid is inner without aperture, thus effectively stop sulfuric acid and anode plate grid to react further, play and slow down anode plate grid corrosiveness.The utility model grid does not have horizontal rib, thus stops because the corrosion of horizontal rib and fracture cause the factor of battery failure, and adopt the storage battery of the utility model anode plate grid structure corrosion-resistant, high temperature resistant, the life-span is long, and normal service life can reach 8 years.

Embodiment
Below in conjunction with figure and embodiment, detailed construction of the present utility model is further described.
As shown in Figure 1 and Figure 2, a kind of battery positive voltage grid of the utility model, comprise lug 1, the bottom of described lug 1 is provided with multiple lengthways of rod 2.
Described lengthways of rod 2 shape of cross section is non-square.
Described lengthways of rod 2 shape of cross section is circular.
Described lengthways of rod 2 circumferencial direction is provided with multiple projection 3.
Described projection 3 is 4.
Operation principle of the present utility model and using method are: in order to be conducive to adopting compression molding process, conveniently comb is installed, lengthways of rod 2 and lug 1 connecting portion are up big and down small taper shape, are circumferentially with protruding 3 at lengthways of rod 2, can play the effect of fine flat fixed calandria.Lengthways of rod 2 cross section is comparatively large, and conductive section is large, and make electrical conductivity hinge structure more unimpeded, catchment effect is good.Anode plate grid adopts extrusion process one-shot forming simultaneously, extrusion process can make the dense structure of anode plate grid, Stability Analysis of Structures, and grid is inner without aperture, thus effectively stop sulfuric acid and anode plate grid to react further, play and slow down anode plate grid corrosiveness.
More than show and describe general principle of the present utility model and principal character; the technical staff of the industry should understand; above-described embodiment does not limit the utility model in any form; the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, all drops in protection range of the present utility model.
