Description

Technical Field

[0001] The present invention relates to the technical field of protective devices for section closing openings of ship cargo holds, and in particular to a protective device for section closing openings of ship cargo holds. Background Art

[0002] The free edges of the cargo hold section closures require protection during the painting process. Currently, both the inside and outside of the closures are protected with tape. Furthermore, the 100-120mm width of the cargo hold section outer plate welds requires protection, requiring multiple coats of tape. After the sections are completed, the tape needs to be removed, but it can become sticky over time, making it difficult to remove. Furthermore, after the tape is removed, the closure area must be re-applied with shop primer to meet process requirements, which also incurs significant labor and paint consumption.

[0003] In view of the above problems, a protective device for the sectional closing opening of a ship cargo hold is urgently needed. Summary of the Invention
