Problems solved by technology

The disadvantage of this solution is that the low-maintenance lead-acid battery generally uses lead-antimony alloy, which has a large amount of outgassing, and the air permeability of the polytetrafluoroethylene filter sheet is significantly reduced after being wetted by water vapor, causing the battery The pressure of the internal hydrogen and oxygen mixed gas increases, and when sparks are generated inside or outside the battery, a battery explosion will occur. The impact force of the explosion will cause the battery shell and exhaust plug cover to shatter, fragments and acid splash, causing property damage or even personal injury

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 , figure 2 with image 3 , Figure 4 , Figure 8 with Figure 9 As shown, the present embodiment battery tank 8, battery cover 7, pole group 9, electrolyte 6, exhaust plug 3 and safety pad 5. The battery cover 7 is a single-layer cover, and the battery tank 8 and the battery cover 7 are injection-molded with high-toughness PP plastic, and the two are bonded together by heat sealing. The exhaust plug 3 is thread-tightly fixed on the liquid injection hole 2 of the battery cover 7 . Each pole group 9 is connected in series by through-wall welding, and each pole group contains a certain number of positive plates, negative plates and separators, and the electrolyte 6 is injected through the liquid injection hole 2 on the battery cover 7, and its main component is diluted Sulfuric acid solution, during normal use of th...

Abstract

The invention discloses an explosion-proof lead-acid storage battery, which comprises a battery container, a battery cover, plate groups, an electrolyte, exhaust bolts and safety pads, wherein the battery cover is a single-layer cover; the battery container and the batter cover are formed by high-tenacity PP plastic in an injection molding manner and are bonded together in a heat sealing manner; the plate groups are connected with one another in series in a through the partition (TTP) welding manner; each exhaust bolt is hermetically fixed to a liquid filling hole of the battery cover via a thread; and each safety pad is arranged at the upper part of each plate group, and floats on the surface of the electrolyte under each liquid filling hole. The explosion-proof lead-acid storage battery can effectively filter an acid mist, and can prevent an external fire source from detonating the battery, and the damage degree to the battery caused by internal sparks is significantly lowered, and the explosion-proof lead-acid storage battery can prevent the electrolyte from overflowing, prevents external dust from affecting use of the storage battery, and can effectively prevent fragments formed after a storage battery housing detonates from hurting people.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and relates to a low-maintenance lead-acid accumulator for automobiles. Background technique [0002] Low-maintenance lead-acid battery is a main lead-acid battery used in automobiles at present. Its battery shell is composed of battery tank, battery cover and exhaust plug. The exhaust plug is fixed on the battery cover through thread sealing. Based on the national environmental protection and product upgrading requirements, it is stipulated that the gas generated by the battery must be filtered before it can be discharged, and the internal and external pressure of the battery is required to be inconsistent. To solve this problem, the current solution is generally to add a polytetrafluoroethylene vapor filter to the inside of the exhaust plug of the lead-acid battery, and the gas will be discharged from the battery after being filtered by the vapor filter. Part of the hydrogen and oxygen ge...
