一种用于散货船的货舱盖结构
By introducing a mechanically interlocked three-dimensional snap-fit sealing structure and multi-stage drainage channels into the cargo hold covers of bulk carriers, the problems of easy fatigue and aging of sealing materials and water infiltration are solved, achieving a more reliable and longer-lasting sealing effect, suitable for cargo transportation in harsh sea conditions.

AI Technical Summary
The existing sealing structure of cargo hatch covers on bulk carriers relies on the compression deformation of elastic materials, which makes the sealing materials prone to fatigue and aging, posing a risk of leakage. Furthermore, it lacks an effective active drainage mechanism, making it impossible to promptly drain infiltrated water.
It adopts a mechanically interlocked three-dimensional snap-fit sealing structure, combining rigid snap-fit and flexible sealing, and integrates multi-level drainage channels to form multiple lines of defense, ensuring sealing reliability, and actively diverting moisture through multi-level drainage channels.
It significantly improves the durability and waterproofing of the sealing structure, reduces the risk of leakage due to material fatigue, extends the service life of the sealing system, and ensures the safety of the cargo hold, especially in harsh sea conditions where it can effectively prevent leakage.
