Description

Lead-acid storage battery cover

Technical Field

The utility model relates to a battery manufacturing technology field specifically relates to a lead acid battery lid.

Background

Lead-acid batteries are widely used in various industries due to their low cost, high reliability and other characteristics compared with other secondary power supplies, and generally comprise a lead-acid battery case and a cover covering the lead-acid battery case. In the widely used lead acid battery in the existing market, generally all can set up the exhaust hole on the lid for in time discharge the steam and the gas that produce in the battery work to the danger of battery explosion because of the internal pressure is too big. However, the existing upper cover structure of the lead-acid storage battery has poor exhaust function, and along with vibration, inversion or other complex working conditions of the storage battery in the actual use process, the problems of blockage of an exhaust hole, unsmooth exhaust and entering of foreign matters into the lead-acid storage often occur, and the danger of explosion caused by overlarge internal pressure of the storage battery possibly exists in the past. And the current battery cover body can only condense a few parts of electrolyte steam during working due to the limited condensation capacity of the battery cover body, and then the electrolyte steam is recycled into the battery box body, so that the electrolyte waste is caused, and the service life of the battery is shortened.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a lead acid battery lid, this lead acid battery lid enable the battery and keep smooth and easy exhaust, and the electrolyte steam rate of recovery is high, has improved the life of battery.

In order to achieve the purpose, the utility model adopts the following technical proposal:

a lead-acid storage battery cover comprises an upper cover body, wherein a plurality of fixing holes are formed in the upper cover body, three to six exhaust holes are transversely formed in the side edge of the upper cover body, each exhaust hole is connected with an exhaust groove, a filter disc is arranged on each exhaust groove, and the exhaust holes and the exhaust grooves are basically in an L shape; and a plurality of groups of condensing channels are also arranged on the upper cover body.

Preferably, the condensing channels are provided with six groups, each group of condensing channels comprises a labyrinth channel and an annular channel, the annular channels are provided with openings, and the labyrinth channels are connected with the annular channels through the openings.

Preferably, the exhaust holes are uniformly distributed on the side edge of the upper cover body.

Preferably, a plurality of stepped annular protrusions are further arranged in the annular channel.

Preferably, the fixing hole is provided in the center of the annular protrusion.

Further preferably, the battery box further comprises a lower cover body, wherein a lower fixing hole corresponding to the fixing hole is formed in the lower cover body, the upper cover body is fixedly connected to the lower cover body through the fixing hole and the lower fixing hole in a threaded manner, the lower cover body covers the battery box body, and an exhaust port and a water return port are formed in the lower cover body.

In the technical scheme, three to six exhaust holes are transversely and uniformly distributed on the side edge of the upper cover body and are connected with the exhaust groove, so that the exhaust capacity of the upper cover body is greatly increased; the filter sheet is arranged on the exhaust groove, and the exhaust hole and the exhaust groove are basically in an L shape, so that gas generated during the operation of the storage battery is filtered by the filter sheet on the exhaust groove and then is exhausted by the exhaust hole, and meanwhile, foreign matters are prevented from entering the exhaust groove and the storage battery box body through the exhaust hole, and the smooth exhaust of the exhaust hole is ensured; the six groups of condensation channels are arranged on the upper cover body, so that the contact area of the upper cover body and the electrolyte vapor is further increased, and the recovery rate of the electrolyte vapor is effectively improved; the labyrinth passage and the annular passage are combined to further guide the electrolyte steam to be in contact with the condensation passage to a greater extent, so that the recovery rate of the electrolyte steam is further improved, and the service life of the storage battery is prolonged.
