Description

A kind of lead-acid accumulator circle rib grid

Technical field

Battery grid technical field is the utility model is related to, specially a kind of lead-acid accumulator circle rib grid.

Background technology

Though grid does not participate in into stream reaction in the battery, main performance such as capacity, life-span to battery, start, fill Electricity reception etc. all has a great impact, and battery-operated person also constantly explores come the structure design to grid for a long time to be changed Enter.

According to the principle of grid, people had many designs to grid structure, and its primary structure is divided into：Surrounding frame, pole Ear, vertical tendon (vertical bars), the horizontal bar (horizontal bar) being connected with vertical tendon.Surrounding grid main function prevents grid in coated plate process Middle deformation, tear, vertical tendon mainly play the transmission function of current, and horizontal bar major function is connected with vertical tendon to support active material Effect.

Grid structure is after change, the grid that has horizontal bar to be more than vertical muscle, has grid that bead structures are radiation, has herringbone Novel grid that shape lattice and thin rib are combined into etc..The capacity of lead-acid accumulator and life-span largely positive pole design, work Skill is manufactured and condition of work is determined, is the design of grid first in the design of positive pole.Excellent grid design, not only makes electricity Flow distribution is uniform, and should have minimum voltage drop loss.

Utility model content

The purpose of this utility model is to provide that a kind of CURRENT DISTRIBUTION is more uniform, and the plumbic acid for being advantageous to heavy-current discharge stores Battery circle rib grid, to solve the problems mentioned in the above background technology.

To achieve the above object, the utility model provides following technical scheme：A kind of lead-acid accumulator circle rib grid, Including frame, lug and the rib being arranged in the frame, the rib is included transverse rod strip, surround centered on grid center The circular rib of setting and the radial rib uniformly dissipated around grid center, at the frame and grid center at the lug Circular rib is connected with the afflux rib of some reinforcements.

Preferably, the rib also includes the reinforcement transverse rod strip and a reinforcement vertical rib strip through grid center.

Preferably, the auxiliary bar strengthened vertical rib strip and V-type is provided with the circular rib.

Preferably, density of the transverse rod strip from grid center to upper and lower both sides tapers into.

Preferably, the afflux rib is provided with three, and afflux rib is connected respectively to grid center and with grid center On the second circular rib of circle.

Compared with prior art, the beneficial effects of the utility model are：

Circular rib of the present utility model and radial rib, which design, make it that the CURRENT DISTRIBUTION of grid is more uniform, and passes through The electric current of afflux is transferred at lug by the afflux rib of reinforcement, is advantageous to heavy-current discharge, grid is in multiple charge and discharge cycles Main corrosion high current concentrated area afterwards, the afflux rib design of reinforcement can extend grid corrosion and break the muscle time, improve and use Life-span.

Brief description of the drawings

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of lead-acid accumulator circle rib grid, including Frame 1, lug 2 and the rib 3 being arranged in the frame, the rib 3 include transverse rod strip 31, the ring centered on grid center Circular rib 32 and the radial rib 33 that is uniformly dissipated around grid center around setting, the transverse rod strip 31 from grid center to The density on upper and lower both sides tapers into, and the circular rib 32 at frame 1 and grid center at the lug is connected with 3 reinforcements Afflux rib 34, three afflux ribs 34 are connected respectively to grid center and with the second of grid center the circular ribs 32 of circle On, the rib 3 also includes the reinforcement transverse rod strip 4 and a reinforcement vertical rib strip 5 through grid center, described to strengthen vertical muscle Bar 5 is provided with the auxiliary bar 6 of V-type with the circular rib 32.

Fig. 2, Fig. 3 are referred to, 0-20mv potential areas of the present utility model accounts for monoblock grid and obtains general area, and is electricity Concentrated area is flowed, and traditional grid 0-20ma potential areas only has the region of monoblock grid forty one, illustrates in current convergence Grid electric current potential drop of the present utility model is lower in region, more uniform compared to the distribution of conventional panels gate current, is advantageous to high current Electric discharge.

In description of the present utility model, it is to be understood that term " coaxial ", " bottom ", " one end ", " top ", " in Portion ", " other end ", " on ", " side ", " top ", " interior ", " front portion ", " center ", the orientation of the instruction such as " both ends " or position close It is to be described based on orientation shown in the drawings or position relationship, to be for only for ease of description the utility model and simplifying, rather than Indicate or imply that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore can not It is interpreted as to limitation of the present utility model.

In the utility model, unless otherwise clearly defined and limited, term " installation ", " setting ", " connection ", " Gu Calmly ", the term such as " spinning " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integrally； Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, can be with It is connection or the interaction relationship of two elements of two element internals, is limited unless otherwise clear and definite, for this area For those of ordinary skill, concrete meaning of the above-mentioned term in the utility model can be understood as the case may be.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
