The cable passes through the compression nut, the compression gasket, the sealing filler rope, the sealing filler and the cup-shaped pipe joint. The cup-shaped pipe joint penetrates through the pressure-resistant shell, the sealing filler is extruded to the surface of the cable through the compression nut, the radial pressing force is gradually increased along with the compression nut, the filler is tightly attached to the cable, the sealing pressure-resistant grade is gradually improved, however, the sealing filler and the cable insulating layer are all made of elastic plastic materials, when the compression nut is tightened, the sealing filler and the cable insulating layer begin to relax in stress, the radial pressing force is gradually reduced along with the prolonging of time, and finally, even completely lost, and sealing failure occurs, so that when the underwater vehicle submerges, particularly when the underwater vehicle sails at a large depth, a water leakage phenomenon occurs, and sailing safety is seriously affected. More seriously, in order to prevent or block the water leakage phenomenon at the cable crossing cabin, sealing filler is often added in the cup-shaped pipe joint in advance, and the screw cap is repeatedly tightened, so that the cable insulation layer becomes thinner and thinner, and finally the cable insulation is failed or even scrapped, and potential safety hazards are left. Therefore, the sealing device for penetrating the cable of the underwater vehicle through the pressure shell is improved.
