AI Technical Summary

Technical Problem

Existing ship collision avoidance measures, such as rubber tires, are easily damaged, affecting the width of the hull and making cleaning inconvenient. The accumulation of algae and shells underwater increases the burden on the ship and damages its structure.

Method used

The system uses an airbag anti-collision component in conjunction with a drive component. When the airbags deploy, they provide anti-collision protection, and when stored, they do not affect the movement of the boat. The drive component drives the sweeper to clean algae and shells from the bottom of the boat.

Benefits of technology

It provides collision protection without affecting the normal navigation of the vessel, and automatically cleans algae and shells from the bottom of the ship, improving the collision protection effect and cleaning efficiency.
