Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
The device of the invention forms an optical fiber protection channel through the cable guide hose and the bell mouth. In the process that the underwater robot and the relay module are connected together and submerge, the channel can effectively protect optical fibers between the underwater robot and the relay module, and can avoid the damage of the optical fibers caused by a plurality of marine animals and complex water flows in a shallow sea area.
The underwater robot and relay module separation process is the most vulnerable key process of the optical fiber. The device disclosed by the invention has the advantages that through reasonable separation step design, the optical fiber is directly exposed in a seawater environment after the underwater robot and the relay module are separated, and the safety of the optical fiber in the separation process of the underwater robot and the relay module is effectively protected.
As shown in fig. 1 to 8, the cable coiling base 1 of the present invention is a plate with holes for binding a cable guiding hose and a bell mouth.
The cable guide hose 2 of the relay module is a corrugated pipe made of plastic, can be flexibly bent while ensuring a certain bending radius, and is not easy to flatten in the diameter direction. The relay module cable guiding hose 2 is bound on the coiled cable base 1 in an 8 shape, the relay module bell mouth 3 is in butt joint with the underwater robot bell mouth 4 and is bound and fixed on the coiled cable base 1, and the underwater robot cable guiding hose 5 is also bound and fixed on the coiled cable base 1 in an 8 shape. According to the 8-shaped binding method of the hose, each circle of hose is independently bound, after the hoses are bound by multiple circles, the effect that the hoses are sequentially pulled off and untied by one circle in the pulling-off process of the hose is achieved, and the bad effect that the hoses are knotted and entangled due to the fact that the hoses are pulled off simultaneously by multiple circles is avoided. The hose is bound by thin wires, wires or ropes, the maximum tension in the pulling-off process is controlled to be not more than F1, the two bell mouths are bound and butted by the thin wires, the wires or the ropes or the magnets, the two bell mouths are also attracted together and butted, the pulling-off separating force of the butt-joint body of the two bell mouths is F2, and F2 is larger than F1 in the invention, so that the two bell mouths are still in a butted state after the hose is completely straightened from an 8-shaped coiled state.
The inner surfaces of the relay module bell mouth 3 and the underwater robot bell mouth 4 are in arc transition, so that the optical fiber can be prevented from being bent and excessively broken. Magnet is arranged on the end face of the horn mouth, and the horn mouth 3 of the relay module can be in butt joint and attraction with the horn mouth 4 of the underwater robot.
The optical fiber remote control underwater robot 8 is provided with a battery, receives the control instruction through an optical fiber cable, and simultaneously feeds back underwater videos, images and working parameters through the optical fiber cable. Compared with the conventional ROV (remote operated vehicle), the diameter of the umbilical cable is reduced from tens of millimeters to less than 1 millimeter, so that the motion flexibility of the underwater robot is greatly improved.
Principle of operation
The relay module 6 is used for relay arrangement of the optical fiber remote control underwater robot 8, an armored umbilical cable is arranged at the top of the relay module 6, and the relay module 6 is arranged through a ship hoisting system. After the relay module 6 carries the optical fiber remote control underwater robot 8 and submerges in the deep sea, the hook device 7 (electric or hydraulic device) is separated, and the relay module 6 arranges the optical fiber remote control underwater robot 8. After the optical fiber remote control underwater robot 8 is separated from the relay module 6, the optical fiber remote control underwater robot 8 pulls off the underwater robot cable guide hose 5 from the cable coiling base 1 circle by circle, integrally pulls off the relay module bell mouth 3 and the underwater robot bell mouth 4 which are bound together, pulls off the relay module cable guide hose 2, the optical fiber remote control underwater robot 8 continues to be far away from the relay module 6 to pull off the relay module bell mouth 3 and the underwater robot bell mouth 4, and the relay optical fiber package 9 and the underwater robot optical fiber package 10 are internally wound with optical fiber cables of tens of kilometers, so that the optical fiber can be orderly laid under the condition of tensile force.
The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by one skilled in the art within the scope of the appended claims without departing from the spirit of the invention. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.
