AI Technical Summary

Technical Problem

Traditional ventilation louvers for sailing ships are not waterproof in bad weather, allowing rainwater to easily seep into the ship's interior. They also have low ventilation efficiency, making it difficult to meet the air circulation needs under different sailing conditions.

Method used

A highly efficient waterproof ventilation louver was designed, comprising an inverted L-shaped ventilation duct, a ventilation fan, waterproof components, and a drainage channel. The waterproof membrane is rapidly unfolded and rolled up via a motor-driven shaft and sprocket transmission system. Combined with a guide plate and drainage channel, rainwater is discharged, and an active ventilation device is provided to accelerate air circulation.

Benefits of technology

It effectively prevents rainwater from entering the ship's interior, protects equipment and cargo, ensures the ship's interior is dry, provides a comfortable working environment, improves ventilation efficiency, and ensures navigation safety.
