The invention discloses a submersible type submarine cable sealing plug device. The submersible type submarine cable sealing plug device comprises a guide cone, a connection shaft, sealing plugs, a pressing plate, an anode block, screws and supporting sleeves, wherein the guide cone, the connection shaft, the sealing plugs, the pressing plate and the anode block form a Haff structure; the guide cone and the connection shaft are in adaptive connection; the multiple layers of sealing plugs are arranged between the connection shaft and the pressing plate; the connection shaft, the sealing plugs and the pressing plate are connected with one another through the screws; the anode block is fixedly connected to the outer side of the pressing plate; one end of each screw is provided with one supporting sleeve; and locking nuts are arranged at the two ends of each screw. The submersible type submarine cable sealing plug device not only can limit movement of a submarine cable inside an outer pipe to prevent the submarine cable from fatigue damage, but also can protect the interior of the outer pipe against damage and prevent marine organisms from adhering to the interior of the outer pipe. The submersible type submarine cable sealing plug device has the beneficial effects of being simple in structure, convenient to mount and high in reliability.
