Abstract

The invention discloses a hydrostatic test device for testing cable cores of submarine optical cables. The hydrostatic test device comprises a cylinder, T-shaped cover plates and plugs. The two ends of the cylinder are open, the T-shaped cover plates cover the two ends of the cylinder and are fixed through fasteners, and the plugs are located in countersunk holes in the T-shaped cover plates and are fixed through fasteners. Each plug is of a through hole structure for cable cores of submarine optical cables to penetrate in. A high-pressure water inlet pipeline and a drain pipeline are welded to the outer surface of the cylinder, the high-pressure water inlet pipeline is connected with a booster pump, and the drain pipeline is connected with a ball valve. The hydrostatic test device is reasonable in structural design, good in sealing performance, easy and convenient to operate, capable of being repeatedly and safely used and capable of testing cable cores of multiple submarine optical cables at the same time; besides, a hydrostatic test and a water penetration length test can be carried out at the same time, so that working efficiency is greatly improved, and testing time is shortened.

Description

technical field [0001] The invention relates to the technical field of submarine optical cable testing, in particular to a water pressure test device used for the core testing of submarine optical cables. Background technique [0002] The submarine optical cable industry needs to carry out hydrostatic test and water seepage length test on the product, and the hydrostatic test is qualified to ensure that the submarine optical cable can work normally in the corresponding water depth; the water seepage length test is used to verify that the cable core seepage length is within Control range. The existing hydraulic device uses a pressure tank, which is not very convenient to open and seal, and only a single water seepage test can be done each time. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a water pressure test device for the core testing of submarine optical cables, which has reasonable structural design, ...
