The utility model relates to a temperature-controllable electric plugging device special for plugging mud, and belongs to the technical field of electric power pipeline hole plugging tools. Accordingto the technical scheme, the device comprises a base, The device mainly comprises a plugging mud mounting part and a heating power part, the plugging mud mounting part is used for mounting plugging mud; Screw cap, Mounting from the head, a pushing baffle and a baffle slideway are arranged in the base; a heating resistance wire is arranged in the container interlayer provided with the plugging mud;the heating power part is used for heating the plugging mud and then keeping a certain temperature; When the device is in use, the power system pushes the blocking mud to flow out of the outlet to block the blocking mud, after the device is used, the power system returns the pushing baffle to the initial position through the control reversing system, then the blocking mud is reinstalled, operation is repeated, and holes of a protection screen, a control cabinet and the like are blocked. The pipeline and hole plugging device has the advantages that pipelines and holes are electrically pluggedthrough plugging mud more efficiently, the working intensity of workers is reduced, the working time is shortened, and the working efficiency is improved.
