Detailed ways

The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the inventive concept. These all belong to the protection scope of the present invention.

The device of the present invention forms an optical fiber protection channel through a fairlead hose and a bell mouth. When the underwater robot and the relay module are connected together for diving, the channel forms an effective protection for the optical fiber between the underwater robot and the relay module, which can avoid the optical fiber caused by numerous marine animals and complex currents in the shallow sea area. damage.

The separation process of the underwater robot and the relay module is the most vulnerable key process for the optical fiber. The device of the invention is designed through reasonable separation steps, so that the optical fiber is directly exposed in the seawater environment after the separation of the underwater robot and the relay module is completed, and the safety of the optical fiber during the separation process of the underwater robot and the relay module is effectively protected.

As shown in FIGS. 1 to 8 , the cable reel base 1 of the present invention is a plate full of holes, used for binding the fairlead hose and the bell mouth.

The fairlead hose 2 of the relay module is a plastic corrugated tube, which can be bent softly while ensuring a certain bending radius, and should not be flattened in the diameter direction. The relay module fairlead hose 2 is bound on the cable base 1 in the shape of an "8", and the relay module bell mouth 3 and the underwater robot bell mouth 4 are butted together, bound and fixed on the cable base 1, underwater. The robot fairlead hose 5 is also bound and fixed on the cable reel base 1 in an "8" shape. The "8"-shaped tying method of the hose is tied independently for each lap. After multiple laps of the hose are tied, the effect of pulling and detaching the hose in sequence during the detachment process can be achieved, so as to avoid multiple laps at the same time and cause the hose to break. Negative effects of knot entanglement. The hose is tied with filament, wire or rope, and the maximum pulling force is not greater than F1 during the control pull-off process. The pulling-off and separating force F2 of the butted body, in the present invention, F2 is greater than F1, so that the two bell mouths are still in the butted state after all the hoses are straightened from the "8"-shaped coiled state.

The inner surfaces of the relay module bell mouth 3 and the underwater robot bell mouth 4 are arc transitions, which can prevent excessive bending of the optical fiber. Magnets are arranged on the end face of the bell mouth, and the bell mouth 3 of the relay module can be docked with the bell mouth 4 of the underwater robot.

The optical fiber remote control underwater robot 8 has its own battery, receives manipulation commands through the optical fiber cable, and feeds back the underwater video, images and working parameters through the optical fiber cable. Compared with the conventional ROV (remotelyoperated vehicle), the diameter of the umbilical cable is reduced from tens of millimeters to less than 1 millimeter, which greatly increases the movement flexibility of the underwater robot.

working principle

The relay module 6 is used for the relay deployment of the optical fiber remote-controlled underwater robot 8. The relay module 6 has an armored umbilical cable on the top, and the relay module 6 is deployed through the ship hoisting system. After the relay module 6 is equipped with the optical fiber remote-controlled underwater robot 8 to dive into the deep sea, the hook device 7 (electric or hydraulic device) is separated, and the relay module 6 deploys the optical-fiber remote-controlled underwater robot 8 . When the optical fiber remote control underwater robot 8 is separated from the relay module 6, the optical fiber remote control underwater robot 8 pulls the water down the robot fairlead hose 5 from the cable base 1 one by one, and pulls off the bundled relays as a whole. The module bell mouth 3 and the underwater robot bell mouth 4, pull off the relay module fairlead 2, and the optical fiber remote control underwater robot 8 continues to move away from the relay module 6, so that the relay module bell mouth 3 and the underwater robot bell mouth 4 are pulled After separation, the repeater fiber optic package 9 and the underwater robot fiber optic package 10 are wound with tens of kilometers of fiber optic cables, and the cables can be laid out in an orderly manner under tension.
