Description

Technical Field

[0001] This utility model relates to the technical field of drainage pipe packing sealing tools, and in particular to a packing sealing device for drainage pipe network inspection and repair. Background Technology

[0002] With the continuous improvement of urban infrastructure, drainage pipe networks, as the "underground lifeline" of cities, play an important role in rainwater drainage and sewage transportation. However, due to factors such as the long service life of the pipe network, the complex underground environment (such as soil corrosion and geological subsidence), and improper daily operation and maintenance, drainage pipe networks are prone to problems such as pipe rupture, joint leakage, and internal wall corrosion. If they are not inspected and repaired in time, they will not only lead to water waste and environmental pollution, but may also cause safety accidents such as road collapse, seriously affecting the normal operation of the city and the quality of life of residents. Therefore, regular inspection and timely repair of drainage pipe networks have become a key link in ensuring the stable operation of urban infrastructure. Existing drainage pipe sealing devices have certain shortcomings. Current single-bladder sealing devices suffer from insecure fixation and poor adaptability. Most commercially available airbag sealing devices are single-bladder structures that achieve sealing by inflating the bladder to fit against the inner wall of the pipe network. However, these devices rely solely on the expansion force of a single bladder for fixation. When the inner wall of the pipe network is uneven or corroded, the bladder cannot fully adhere to the wall, easily leading to localized leakage. Furthermore, the single bladder has limited support points, making it prone to displacement due to water flow impact or pipe network vibration, resulting in sealing failure. In addition, existing airbag sealing devices have a narrow pipe diameter compatibility range; a single airbag specification is typically only suitable for pipe networks with a specific diameter. Given the coexistence of multiple pipe diameters in urban drainage networks, multiple sets of sealing devices of different specifications are required, increasing operation and maintenance costs and equipment management difficulty. Therefore, improvements are needed to address these issues. Utility Model Content

The four airbags 6 and four inflatable airbags 7 are staggered and installed, with the inner sides of the four inflatable airbags 7 respectively connected to the outer sides of the four support plates 5, and the inner sides of the four airbags 6 connected to the outer sides of the first support tube 2. The second fixing mechanism includes a first airbag ring 11 located at the rear end of the barrier airbag 4 and a second airbag ring 12 located at the rear end of the first airbag ring 11. The first airbag ring 11 and the second airbag ring 12 facilitate the support and fixing of the rear end of the device. On the other hand, it is convenient to cooperate with the air pump 8 to inflate the filling airbag 6 and the expansion airbag 7; the diameter of the first airbag ring 11 is larger than the diameter of the second airbag ring 12. The first airbag ring 11, the barrier airbag 4 and the second airbag ring 12 are all equipped with valve ports 13, which facilitates the connection of the air pump 8 for inflation; and the barrier airbag 4 has multiple through slots that are equidistantly opened. The air pump 8 is installed on the rear end face of the barrier airbag 4. The air pump 8 is connected to three air supply pipes, and the other end of the three air supply pipes is connected to the three valve ports 13 respectively.

[0016] In this invention, four first corrugated tubes 9 are equidistantly connected to the second airbag ring 12. The first corrugated tubes 9 are located inside the first airbag ring 11, and the other end of the first corrugated tubes 9 passes through the through groove of the barrier airbag 4 and connects to the filling airbag 6.
