Abstract

The invention discloses a pipeline interior rapid self-locking blockage device and belongs to the technical field of pipeline blockage. The pipeline interior rapid self-locking blockage device is reliable in blockage and can achieve flow guiding. According to the adopted technical scheme, a blockage unit is an inflatable blockage device and is provided with an axial through hole; a traction unit is of a structure with an electric control valve mounted on a hollow pipe, and an outer thread is formed on the hollow pipe; a tensioning unit comprises the structure that axial through holes are formed in a fixed seat and a movable seat correspondingly, the fixed seat and the movable seat are connected through a spring, one ends of first supporting rods are hinged to the fixed seat, antiskid blocks are hinged to the other ends of the first supporting rods, one ends of second supporting rods are hinged to the movable seat, and the other ends of the second supporting rods are hinged to the middles of the first supporting rods; and the hollow pipe penetrates through the tensioning unit and then is fixed to the blockage unit together, a first gear and a sleeve are mounted on the hollow pipe ina sleeving mode, and a second gear is fixed to an output shaft of a motor and engaged with the first gear. The pipeline interior rapid self-locking blockage device is used for pipeline blockage.

Description

technical field [0001] The invention relates to a quick self-locking plugging device in a pipeline, which belongs to the technical field of pipeline sealing. Background technique [0002] With the continuous increase of the operation time of the pipeline network and the increase of the service life of the pipeline, due to the defects of its own materials, the corrosion of the conveying medium, the interference of the outside world and other factors, some leakage problems will occur in the pipeline, which will lead to greater dangers in the transportation operation. Among them, some pipe sections need to be repaired or replaced without losing power. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and the technical problem to be solved is to provide a fast self-locking sealing device in a pipeline that is reliable in sealing and can realize flow diversion. [0004] In order to solve the above-mentioned technical problems, the te...
