Problems solved by technology

However, some special working conditions in the project require the arrangement of lead-acid batteries in groups. In addition, there is not enough heat dissipation space in the location, so that the internal temperature of the lead-acid battery gradually rises. The temperature rise will inevitably lead to the softening of the thin wall of the bottom case The outer drum is deformed, thereby reducing the sealing performance and electrical performance of the lead-acid battery in use
Once the built-in electrolyte of the supporting lead-acid battery leaks, it will inevitably deteriorate the supporting environment, resulting in unnecessary economic losses

Embodiment Construction

[0011] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0012] figure 1 The reinforced structure of the lead-acid battery bottom case shown is composed of the wall plate 1, the rib 2, the transverse partition plate 3, the longitudinal partition plate 4 and the side wall plate 5. Rectangular cavity, the opening of the cavity faces upwards, and there are 6 built-in compartments of equal size in this embodiment. The built-in grid is arranged in two horizontal columns, and each column is arranged with three. In this embodiment, the long side size of the built-in grid is set to be B. In order to improve the thermal deformation resistance of the bottom shell, vertically protruding solid rectangular ribs 2 are arranged at equal intervals on the outer wall of the wall panel 1 of the bottom shell, and their positions are located in the middle of the long side of the built-in grid. In this embodimen...

Abstract

The invention discloses a strengthening structure for a bottom shell of a lead-acid storage battery. The strengthening structure comprises face wall plates, ribs, transverse partition plates, longitudinal partition plates and side wall plates, wherein a rectangular cavity with internal grids is formed by the transverse partition plates and the longitudinal partition plates, and an opening of the cavity is upward. The entity rectangular ribs which are vertical and convex are arranged on the outer walls of the face wall plates at equal intervals. The convex ribs are additionally arranged on theouter walls of the face wall plates at the two sides of the bottom shell, and the external ribs are directly arranged in a thermal deformation weak region, a structure strengthening effect is good, and the heat deformation resistance of the bottom shell can be remarkably improved. The strengthening structure is particularly suitable for being matched with the bottom shell of an energy-storage lead-acid storage battery.

Description

technical field [0001] The invention relates to an accessory of a lead-acid storage battery. Specifically, the invention relates to a bottom case of a lead-acid storage battery, in particular to a reinforcement structure for a bottom case of a lead-acid storage battery. Background technique [0002] The casing of the lead-acid battery is composed of two parts, the bottom case and the upper cover, and the bottom case is mainly used for containing electrolyte in the structure. The electrolyte of the lead-acid battery is dilute sulfuric acid. In order to prevent the pollution caused by the overflow of this corrosive liquid, under the existing technological conditions, the bottom shell of the lead-acid battery is preferably made of plastic. The bottom case is actually a thin-walled rectangular open cavity. This type of component is easy to form by injection molding, and the production cost is also very low. The most important thing is that the plastic bottom case meets the requi...
