AI Technical Summary
In the existing technology, the welding construction of embedded propeller channels is difficult and labor-intensive, and stress concentration is prone to occur, making it difficult to guarantee smoothness and construction quality.
An arc-shaped plate is installed between the main body of the propeller channel and the outer plate of the hull. The curvature of the arc-shaped plate is determined according to the curvature of the connection point. The plate is then bent and welded to the propeller channel and the outer plate of the hull to reduce the amount of welding and grinding work and to avoid welding at locations with significant curvature changes.
It reduces construction difficulty, decreases stress concentration at welded joints, improves the smoothness of the flow channel and welding quality, and simplifies the construction process.
