[0011] Beneficial effects of the utility model:

[0012] When the utility model is in use, the pipeline leak repair device can be clamped on the outside of the pipeline through two arc-shaped covers. When the arc-shaped covers are fixed, the arc-shaped cover plate is aligned with the pipeline leak position, the arc-shaped cover can be fixedly connected by the arranged locking bolts and ear plates, and the arc-shaped cover plate can be compressed by the arranged clamping assembly, so that the first sealing ring is tightly against the outer wall of the pipeline, thereby sealing the leak point, and the arranged second sealing ring can play a secondary sealing role, thereby completely covering the leak point.
