The invention provides an internal plugging device of a pipeline. The internal plugging device comprises a central pipe. A guide cone is arranged at one end of the central pipe. A hydraulic drive sluice valve is arranged at the other end of the central pipe. A connection flange, a first lifting lug, a flange connection disk, a hydraulic cylinder, an execution sleeve, a flat key, a second lifting lug, a deblocking ring, an anchoring device, a shearing semi-ring, a sealing device, a shear-resistant semi-ring and the guide cone are sequentially arranged on a pipe body of the central pipe from the end where the hydraulic drive sluice valve is arranged to the end where the guide cone is arranged. The first lifting lug and the second lifting lug are connected with an assistance mechanism respectively. The internal plugging device can be used for blocking a large-diameter pipeline, is reasonable in structural design and easy and convenient to operate, and can guarantee stability and reliability of blocking.
