Abstract
The invention discloses a submarine cable bending limit device comprising an electrical cable clamp and limiters. The limiters are connected by means of series sleeved connection. The electrical cable clamp and the limiters are provided with electrical cable through holes inside, and are divided into two symmetrical half structures through the center lines. The front end of each limiter is internally provided with a slot, and the tail end of each limiter is provided with a flange. The limiters are in series sleeved connection through a Hough structure formed by clamping the flanges into the slots. There is a certain gap between each flange and the corresponding slot. Each limiter is further provided with a monitoring optical cable through hole on the same horizontal line as the center line of the electrical cable through hole, and the center lines of the monitoring optical cable through hole and the electrical cable through hole are not concentric. The bending radius of an electrical cable can be controlled effectively, and thus, the electrical cable can be prevented from being broken due to over-bending under the sea. The bending condition of a submarine cable can be monitored in real time. Under impact, a monitoring optical cable is damaged first, the damaged monitoring optical cable can be found in a timely manner, and measures can be taken to avoid damage to the limiters.
