Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, and in particular relates to an auxiliary device and method for cable frame tightness testing. Background Technology

[0002] The tightness of ship compartments is a crucial aspect of shipbuilding. Whether through hydrostatic or pneumatic testing, the purpose is to verify the airtightness of the hull structure, ensuring that there will be no leaks during navigation. Since the tightness test of empty compartments is often conducted before the cables are installed, when all power cables are not yet laid, but the shipowner requires the tightness test to be performed first to ensure all structural welds are flawless before laying the cables, the conventional method involves welding sealing plates to the cable frames. This process is inflexible in confined spaces, and the sealing plates must be removed with a cutter after the tightness test, which is both time-consuming and labor-intensive. Summary of the Invention
