Lead-acid battery with protective structure

Abstract

A lead-acid storage battery with a protective structure, including an outer steel shell, chute slots are provided at the four corners inside the outer steel shell, and second springs are installed inside the chute; the inside of the chute slides Connect the slider, the bottom end of the slider is in contact with the second spring, each of the sliders is fixed at the four corners of the bottom plate; the top of the bottom plate is fixed with a cooling rod, and the cooling rod Several heat dissipation holes are provided on the surface; air inlet holes are provided at the bottom of the bottom plate, and the air inlet holes communicate with the heat dissipation holes; the outer steel shell is used to store batteries, and jacks are provided inside the batteries; The socket is matched with the cooling rod. The lead-acid battery with a protective structure disclosed by the present invention assembles the battery through an outer steel shell, which can effectively prevent damage to the battery body due to bumps during the production, installation, and maintenance of the battery, and avoid damage to the battery shell and damage to the battery body. Leakage, prolong battery life.

Description

technical field [0001] The invention belongs to the technical field of lead-acid batteries, and particularly relates to a lead-acid battery with a protective structure. Background technique [0002] Lead-acid battery is a kind of acid battery, the positive electrode is lead dioxide, the negative electrode is spongy lead, the electrolyte is sulfuric acid aqueous solution, and the separator or diaphragm uses microporous rubber separator and microporous plastic separator according to different types of lead batteries. Or other materials, the battery shell is made of hard rubber, engineering plastics, FRP and other materials. [0003] The traditional large-capacity 2V battery usually adopts the internal multi-cell parallel design. This design has unfavorable factors such as easy bulging and cracking of the ABS shell, leakage at the joint of the rubber-sealed shell cover, and short service life. There will be damage to the battery case due to some brutal operations or unintentio...

Problems solved by technology

[0003] Traditional large-capacity 2V batteries usually adopt an internal multi-cell parallel design. This design has disadvantages such as easy bulging and cracking of the ABS shell, liquid leakage at the junction of the rubber-sealed shell cover, and short service life; There will be damage to the battery case due to some brutal operations or unintentional bumps, and there are also risks such as liquid leakage, which poses a great safety hazard
