Anchor smashing test system of submarine cable

The invention relates to an anchor smashing test system of a submarine cable. An effective anchor smashing test system is lacked to simulate an anchor smashing test effect at present. The anchor smashing test system comprises fixed pulleys for supporting and locating the tested submarine cable, and anchor devices connected with the two ends of the tested submarine cable, wherein the fixed pulleys are symmetrically arrayed at the left side and the right side of the submarine cable; the anchor devices are connected with tension sensors; the tension sensors are connected with ground anchors; an iron anchor capable of falling and rising for an anchor smashing test is hung above the middle of the tested submarine cable; the iron anchor is connected with a lifting device via an anchor cable; the lifting device and the tension sensors are connected with a control machine via a digital interface; and the control machine is used for controlling operation of the lifting device and has a bidirectional man-machine intera
