AI Technical Summary
Existing drainage pipe sealing devices are prone to displacement during use due to reduced friction of the airbag, resulting in unstable sealing. Furthermore, separate sealing devices are required for pipes of different diameters, increasing equipment investment costs and operational complexity.
The gas-driven sealing device uses a cylinder drive and a rotating structure of the adapter frame to achieve linkage between the airbag sealing and the support base, adapting to different pipe diameters. Combined with inflation control, it enables rapid installation and removal, reducing equipment investment costs and improving sealing stability.
It has improved the stability and reliability of the sealing process, reduced equipment investment costs, simplified the operation process, enabled a single person to complete the work, shortened the sealing time, and improved construction efficiency.
