Description

OPZV battery

Technical Field

The utility model relates to an extensive use is in communication, electric power, subway, energy storage, the fixed colloid valve accuse long-life OPZV battery in fields such as UPS, and the grid device is a part of battery, belongs to lead acid battery technical field.

Background

The OPzV battery is a colloid battery, and the electrolyte of the OPzV battery is solidified and does not flow, so that the battery can be placed horizontally. The customer can freely select to put the battery horizontally or vertically according to the space size. Because the pole group of the OPzV battery cannot be tightly assembled in the battery case due to the requirement of glue pouring, the pole group has a larger gap in the battery case, and when the battery case is sealed with the cover, the pole column possibly deflects to one side when passing through the battery cover, so that the center of the pole column cannot be absolutely consistent with the center of the battery cover; when the pole group is welded improperly, the pole can be welded askew, so that the pole and the battery cover cannot be on the same central line. Two problems are caused, namely, the pole group is not centered in the shell, the uniform distribution of gel around the pole plate is influenced, and the performance of the battery is influenced; when two batteries are connected, the connecting bar is fixed on the screw hole of the pole by a screw, the pole screw hole which is not on the central line can lead to stress during connection, and serious pole deflection can directly lead to the failure of connection and the scrapping of the batteries. Meanwhile, in the service life of the long-life OPzV battery, if the battery is laid horizontally, the polar column of the long-life OPzV battery presses the battery cover in one direction for a long time, the lasting pressure always acts on the polar column glue and the battery cover, and finally the lasting pressure can be released on the battery cover and the polar column sealing glue to cause the deformation of the polar column and the battery cover, even the sealing of the polar column can be damaged, so that liquid leakage is caused, the performance of the battery is influenced, the battery fails, and the loss is caused to customers.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect, the utility model aims to provide a rational in infrastructure, OPZV battery life's OPZV battery.

Therefore, the utility model adopts the technical scheme that: the OPZV battery comprises a battery shell (1), wherein a battery cover (2) matched with the battery shell (1) is arranged at the upper part of the battery shell (1);

the battery cover (2) is provided with a battery cover hole for installing a battery pole (3), the battery pole (3) penetrates into the battery shell (1) through the battery cover hole, a battery grid (4) is arranged on the upper portion, located in gel, of the battery shell (1), the grid hole concentrically arranged with the battery cover hole is formed in the battery grid (4), and the bottom of the battery pole (3) penetrates into the grid hole.

Furthermore, a pole rubber ring (5) arranged outside the battery pole (3) is arranged in the battery cover hole, and the pole rubber ring (5) is tightly clamped between the battery cover hole and the battery pole (3).

Furthermore, a circle of convex ring (51) protruding outwards is arranged on the surface of the lower part of the pole rubber ring (5), and the convex ring (51) is positioned below the lower surface of the battery cover (2), so that a blocking resistance to the upward movement of the pole rubber ring (5) is formed.

Furthermore, the upper surface of the battery cover (2) is provided with a pole gland (6) for limiting the pole rubber ring (3).

The utility model has the advantages that: when the OPzV battery is assembled, a grid device is additionally arranged at the root part of the pole so as to ensure the pole, a battery cover hole passes through a central line, and a pole group is also positioned in the center of the shell; in addition, the stress generated by long-time horizontal placement of the pole can be effectively eliminated; the gel can be ensured to be uniformly distributed around the polar plate; the grid can also keep the battery in a horizontal state, and the gel can be prevented from collapsing and stacking due to the influence of gravity. Only then is it possible to ensure a service life of the OPzV cell of up to 20 years.

Detailed Description

The OPZV battery comprises a battery shell 1, wherein a battery cover 2 which is matched with the battery shell 1 is arranged at the upper part of the battery shell 1;

the battery cover 2 is provided with a battery cover hole for installing a battery pole 3, the battery pole 3 penetrates into the battery shell 1 through the battery cover hole, a battery grid 4 is arranged on the upper portion, in gel, of the battery shell 1, the grid hole concentrically arranged with the battery cover hole is formed in the battery grid 4, and the bottom of the battery pole 3 penetrates into the grid hole.
