Description

Valve-controlled storage battery groove

Technical Field

The utility model relates to a battery technical field specifically is a valve accuse formula battery cell body.

Background

The storage battery can realize conversion between chemical energy and electric energy, realizes recharging through reversible chemical reaction, is a secondary battery, utilizes external electric energy to regenerate internal active substances during charging, stores the electric energy as the chemical energy, and converts the chemical energy into the electric energy to output and supply power when needing to discharge; the battery is in the back level of charging, its inside will produce a large amount of explosive gases, if it will lead to battery internal pressure to be bigger and bigger in lasting in the battery always, the bulging problem appears in final battery, lid and the cell body of battery are because internal pressure is too big and alternate segregation, the electrolyte that has corrosivity reveals easily and leads to environmental pollution in the environment, although the air vent has been seted up at the battery, the easy quilt of air vent leads to the exhaust process not unblocked by the foreign matter jam, carminative process is prolonged, make the battery cell body need bear great pressure, if can solve above-mentioned problem, to the life who improves the battery cell, it will have positive meaning to solve the bulging problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a valve accuse formula battery cell body to solve the problem mentioned in the background art.

In order to achieve the purpose, the utility model provides a following technical scheme, including cell body and a plurality of baffle, both sides are equipped with the draw-in groove of a plurality of position symmetries around the cell body inner chamber, the cell body left and right sides is equipped with the collecting chamber symmetrically, the collecting chamber with the cell body is linked together, place the gasbag in the collecting chamber, the gasbag with the shape matching of collecting chamber, the both ends of baffle can be inserted and locate in the draw-in groove with the inner chamber partition of cell body is the cell that holds the polar plate.

Preferably, the edge of the containing chamber is further provided with a limiting clamping block for clamping the air bag.

Preferably, the limiting clamping block and the air bag are of an integrated structure.

Preferably, the balloon is in particular a PP balloon.

Preferably, the front side and the rear side of the inner cavity of the groove body are symmetrically provided with 6 clamping grooves.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

the utility model provides a pair of valve accuse formula battery cell body uses cell body and the cooperation of battery cover body during the use, when having a large amount of gases to produce in the battery, the pressure grow in the cell body, and the gasbag is compressed under the effect of pressure this moment, and the volume of gasbag reduces because of the compression, and the pressure that the suppression battery is inside increases for the air vent has more abundant time to remove the unnecessary gas of discharge, can reduce the appearance of battery bloated problem.

The utility model discloses can restrain the inside pressure increase of battery, reduce the appearance of the bloated problem, avoid electrolyte to reveal, have practical meaning and spreading value, expect to produce good economic benefits.

FIG. 1 is a schematic perspective view of the present invention;

FIG. 2 is a schematic sectional view of the tank;

in the figure: the device comprises a groove body 1, a clamping groove 11, a containing chamber 12, an air bag 13, a limiting clamping block 14, a partition plate 2 and a cell 21.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

With reference to fig. 1-2, a valve-regulated storage battery cell body comprises a cell body 1 and 3 partition plates 2, 6 clamping grooves 11 with symmetrical positions are arranged on the front side and the rear side of an inner cavity of the cell body 1, storage chambers 12 are symmetrically arranged on the tops of the left side and the right side of the cell body 1, the storage chambers 12 are communicated with the cell body 1, air bags 13 are placed in the storage chambers 12, the air bags 13 are matched with the storage chambers 12 in shape, limiting clamping blocks 14 for clamping the air bags 13 are further arranged on the edges of the storage chambers 12, the limiting clamping blocks 14 and the air bags 13 are of an integrated structure, and two ends of each partition plate 2 can be inserted into the clamping grooves 11 to separate the inner cavity of the cell body 1 into unit lattices 21 for containing polar plates.

The tank body 1 refers to a tank body of a storage battery and is matched with a storage battery cover body; the air bag 13 is made of PP material, has an elastic air bag structure, is extremely difficult to be corroded by electrolyte, and has low manufacturing cost; the separator 2 is a plate-shaped component which plays a role in division, and the separator 2 is inserted into different clamping grooves 11 so as to be suitable for polar plates with different sizes.

The utility model discloses the theory of operation: the cell body and the storage battery cover body are matched for use during use, when a large amount of gas is generated in the storage battery, the pressure in the cell body is increased, the air bag is compressed under the action of the pressure, the volume of the air bag is reduced due to compression, the pressure in the storage battery is restrained to be increased, the vent hole has more abundant time to discharge redundant gas, and the problem of swelling of the storage battery can be reduced.
