一种长循环寿命阀控式铅酸蓄电池液位监测结构

Abstract

本实用新型提出了一种长循环寿命阀控式铅酸蓄电池液位监测结构，涉及液位监测技术领域，包括监测浮板，所述监测浮板的顶端固定安装有对其进行导向支撑的连接导杆，所述连接导杆的顶端固定安装有对铅酸蓄电池进行密封的密封板，所述密封板的顶端固定安装有进行液位指示的指示标。本实用新型的优点在于：利用电解液的浮力对监测浮板进行支撑，使监测浮板在重力和浮力影响下能够随电解液的液位高度进行升降，同时监测浮板升降带动连接导杆和密封板驱动指示标在指示套壳的内部进行移动，通过指示标在指示套壳内部的位置显示判断电解液的液位高度，便于从铅酸蓄电池的内部进行液位监测，降低其他因素对监测结果的影响，提高监测的精确性。
