AI Technical Summary

Technical Problem

Existing airbag-based water-blocking methods are prone to bursting, causing water to rush down the pipes, posing a safety hazard to workers in the well chamber or pipes. Furthermore, brick-based blocking methods consume a lot of manpower and resources and are complicated to dismantle.

Method used

A pipeline rescue and safety device was designed, including a pipe, a main baffle and a secondary baffle, which are connected by connecting bolts. The main baffle and the secondary baffle are provided with a drain port. The opening and closing of the drain port is controlled by a detachable handle. Combined with a sealing ring and a guide structure, the sealing performance and stability are ensured.

Benefits of technology

This avoids safety accidents caused by airbag rupture and brick blockage removal, reduces material and labor consumption, improves construction efficiency, ensures worker safety, and simplifies the construction process.

Abstract

This utility model discloses a pipeline rescue and safety device, belonging to the field of pipeline repair. It includes a pipe tube with a main baffle fixedly connected to its top. A sealing gasket is placed between the pipe tube and the main baffle. A secondary baffle, coaxially arranged with the main baffle, is connected to the top of the main baffle via connecting bolts. The main baffle has a first drain port, and the secondary baffle has a second drain port corresponding to the first drain port and of the same size. The secondary baffle can rotate around the connecting bolts, and the rotation of the secondary baffle controls the opening and closing of the first and second drain ports. A sealing ring groove is provided on the main baffle at the edge of the first drain port. This pipeline rescue and safety device replaces traditional methods of using airbags and bricks to block water, avoiding safety accidents caused by water leakage due to airbag rupture, and also solving the accident risk caused by sudden water gushing out when removing brick plugs, thus ensuring the safety of personnel working in manholes or pipes.
