Abstract
The present invention relates to a deep-sea bottom optical cable end moulded sealing method and a system thereof, which is used for sealing heads of deep-sea bottom optical fiber communication cables. The present invention adopts injection molding for sealing the end head of an optical cable, and the end heads of the optical cable can be sandwiched in a sphere cavity of a module by an upper mould and a lower mould; the upper mould and the lower mould are tightly fixed by a high-strength bolt, and molten polyethylene by heating is injected into the sphere cavity of a module through an injection molding hole connected with a flange. Simultaneously, an electric heating bar on a device can be heated for making the injected molten polyethylene not solidified immediately, and the molten polyethylene can be uniformly coated on the periphery of the end head of the optical cable; then the molten polyethylene is cooled. The system required for using the method is composed of a deep-sea bottom optical cable end moulded sealing device, a computer integrated controller, a power supply distributor box, an injection molding machine and a cooling device. The present invention has the advantages that because air bubbles possibly existing in the molten polyethylene are exhausted by a release valve through a thin passage beside the sphere cavity and a compact plastic protective layer is formed on the end head of the optical cable without air bubbles in the sealed end head of the optical cable by injection molding, the optical cable can bear great pressure without damage under 9000-depth water.
