The present invention relates to a device for repairing a cable insulation layer in deep sea in situ. The device comprises a frame, underwater electric wheels are installed at the four corners of thebottom of the frame respectively, and a seabed sediment landfill device and a seabed sediment sucking and removing device are installed at the position, located above the underwater electric wheels, of the frame. A cable insulation layer repairing mechanism is fixedly installed in the frame, arc-shaped fixing blocks are arranged on the frame on the two sides of the cable insulation layer repairingmechanism, and a cable taking and placing mechanism is installed at the bottoms of the arc-shaped fixing blocks. An underwater high-pressure air device, an underwater glue supplementing device and anunderwater water pumping device are further fixedly installed on the frame. The device is convenient to repair the cable insulation layer, capable of directly working underwater without being transported to the land, time-savi
