The invention relates to the technical field of pipeline maintenance reparation, in particular to a trenchless petroleum pipeline breakage reparation device including a main shaft shell body, a visualdetection mechanism, expansion adjusting mechanisms, walking mechanisms, an air pump, a power supply, an airbag , glass fiber felt-cloth, and a controller. The expansion adjusting mechanisms are arranged at two ends of the main shaft shell body, the movement direction of the output ends of the expansion adjusting mechanisms is arranged in a radial mode along the main shaft shell body, the visualdetection mechanism is mounted on the side, located at the head end of the main shaft shell body, of the expansion adjusting mechanisms and is fixedly connected with the expansion adjusting mechanisms, the walking mechanisms are arranged at the output ends of the expansion adjusting mechanisms, the airbag warps the outer wall of the main shaft shell body, the air pump and the power supply are arranged in the main shaft shell body separately, the output end of the air pump extends out of the main shaft shell body to be connected with the airbag, and the glass fiber felt-cloth infiltrated with repair slurry is attached to the outer wall of the airbag. According to the scheme, the device can move in pipelines independently, the size is convenient to adjust so that the pipelines with differentdiameters can be adapted, the adjustment is convenient, and the structure is stable.
Description
technical field [0001] The invention relates to the technical field of pipeline maintenance and repair, in particular to a non-excavation oil pipeline damage repair device. Background technique [0002] With the development of the petroleum industry, more and more pipelines are used in the field of petroleum transportation. Corrosion and rupture of pipelines will inevitably occur during long-term use. At this time, pipeline repair is very important. The restoration of pipelines is divided into excavation and non-excavation restoration methods, among which the excavation restoration method has a higher repair cost, and the non-excavation restoration can effectively save costs. [0003] The current non-excavation repair methods mainly include UV curing repair technology, spot repair technology, folded lining repair technology and polymer material repair technology. [0004] 1. Ultraviolet curing repair technology (for the whole repair) [0005] UV-curing CIPP repair technolo...
