Problems solved by technology
[0003] Because the sealing of the hole is under the liquid surface, the sealing level of the hole is high, and there are special requirements for the sealing material of the hole, and the sealing construction process is also relatively complicated. Not only the material is expensive, the construction cost is high, and the maintenance of the optical cable in the later stage is also very difficult. inconvenient

The invention particularly relates to a sealing device of an optical cable liquid penetrating cabin. The device comprises two communicating pipes, the two communicating pipes are communicated with thetop of the liquid tank at an interval; a cavity is formed in the communicating pipe; the bottom of the cavity is communicated with the top of the liquid tank; a protective cover is fixed at the top of the cavity; a communicating cavity is hollowed out in the protective cover; at least one optical cable is inserted into the communication cavity and the cavity. The optical cable is guided by the two communicating pipes to penetrate through the liquid tank along the top of the liquid tank, so that a penetrating hole is prevented from being in a liquid state, the sealing grade of the hole is greatly reduced, the problem of expensive sealing materials is solved, the complexity of a construction process is avoided, the overall cost is reduced, later maintenance is performed along the top, and the convenience is high.
Description
technical field [0001] The application relates to the field of shipbuilding, in particular to a sealing device for an optical cable passing through a liquid tank. Background technique [0002] In the manufacturing and processing of ships, the laying of optical cables in ships is relatively common, and the laying of optical cables usually adopts the method of penetrating the bulkhead. When penetrating a tank filled with liquid, it is necessary to seal the penetrating hole. [0003] Because the sealing of the hole is under the liquid surface, the sealing level of the hole is high, there are special requirements for the sealing material of the hole, and the sealing construction process is also complicated, not only the material is expensive, the construction cost is high, and the maintenance of the optical cable in the later stage is also very difficult. inconvenient. Contents of the invention [0004] The purpose of this application: to reduce the sealing level of the hole...
