Abstract
The invention discloses a test method and device for seabed cable tensility torque which can use horizontal and vertical ways, characterized in that the device comprises following components: (1) a fixed clamp for clamping the seabed cable, (2) an optical cable sample for the tested seabed, (3) a measuring device for displacement, (4) a rotatable clamp with an angle sensor, (5) a stretching sensor, (6) a counter poise and counter poise bracket, (7) a stretching converter, (8) an angle converter, (9) a displacement converter , (10) a centre processor, (11) a light power meter, (12) light source. After the method respectively processes optical connection and electrical connection for the test instruments and devices and forms the integral test devices, the method opens the light source and a stretching tester to observe and record the parameters of the light declining quantity, the tensility, the flexible strain capacity, the rotating direction of the cable and the angle of the seabed cable. The advantages of this invention is taking the parameters obtained by the test as import scientific foundation for research, design, production, technique and construction and maintenance of guide of the seabed cable for the leaders and scientific stuffs developing the relevant working decision.
Description
Technical field [0001] The invention relates to a test method and a test device for detecting the tension torque of a submarine optical cable. Background technique [0002] In the manufacture of submarine optical cables, a large internal stress will be introduced when twisting the outer armored steel wire. It is closely related to the structure, process design and manufacturing quality of submarine optical cables. When the submarine optical cable is stretched, the internal stress will cause different directions and different degrees of torsion, so a certain tension must be applied during the construction of the submarine optical cable to overcome this torsion, but too much tension will endanger the performance of the cable. . When the submarine optical cable is damaged due to various reasons such as anchor pulling, when the damaged section is salvaged and repaired and the damaged section is cut off, the sudden sudden change of internal stress will cause the cable to twist ...
