AI Technical Summary

Technical Problem

In existing technologies, when ships are sailing at sea, the swaying caused by waves and wind causes uneven electrolyte distribution inside the battery, leading to performance fluctuations, shortened lifespan, and safety hazards. Furthermore, existing active compensation schemes are complex in structure and have delayed response.

Method used

Design a battery protective shell with water stabilization function. By setting a limiting guide rail and a sliding extension rod structure inside the shell, combined with a float plate and a water storage area, the electrode plates can be adaptively adjusted by the buoyancy of the water to ensure attitude stability. The water flow path can be controlled by a water baffle and a heat exchange groove structure to achieve passive stabilization and efficient heat dissipation.

Benefits of technology

It can maintain battery stability in complex dynamic environments without the need for active driving components, reducing system complexity and cost, extending battery life, and improving safety and response speed.

Abstract

This utility model relates to the field of marine battery installation and protection structure technology, and particularly to a battery protective shell with water stabilization function. It includes a placement shell and an electrode plate. Limiting guide rails are provided on both sides inside the placement shell. Extension rods are provided on both sides of the electrode plate. A float plate is sleeved on the surface of the electrode plate, and a water storage area is formed between the float plate and the placement shell. This utility model, by providing limiting guide rails inside the placement shell and slidably engaging extension rods on both sides of the electrode plate, combined with the float plate sleeved on the outside of the electrode plate and the water storage area formed between it and the placement shell, allows the electrode plate to adaptively adjust itself during hull rocking or tilting by relying on the buoyancy of the water on the float plate, thereby maintaining the stability of the electrode plate's attitude. The water-passing hole design on the surface of the float plate allows water to flow back between different areas, improving the sensitivity and balance of the float plate's follow-up response.
