Optical fiber floating bag device for underwater robot

Abstract

The invention belongs to the technical field of underwater robots, and particularly relates to an optical fiber floating bag device for an underwater robot. The device comprises an optical fiber micro cable, a floating ball, a metal hose, a protective sleeve connecting piece, a protective sleeve and a rigid guide pipe, the protective sleeve is arranged at the lower end of the floating ball through the protective sleeve connecting piece, the rigid guide pipe penetrates through a stabilizing wing to be connected with a frame of the underwater robot, and the two ends of the metal hose are connected with the rigid guide pipe and the protective sleeve respectively. The optical fiber micro cable sequentially penetrates through the rigid conduit, the metal hose and the floating ball to the water surface end. The interior of the whole optical fiber channel is smooth, and the resistance is small. The device is stable and controllable in the water state. The situation that the optical fiber directly extending out of the carrier end is wound with the robot is avoided, the carrier end optical fiber is guided, the safety of the carrier end optical fiber is improved, and the device is laid and recycled along with the underwater robot and does not depend on external equipment.

Description

technical field [0001] The invention belongs to the technical field of underwater robots, in particular to an optical fiber floating bag device for underwater robots. Background technique [0002] ARV (Autonomous and Remotely-operated Vehicle) is a new concept of underwater robot, which integrates the advantages of Remotely Operated Vehicle (ROV) and Autonomous Underwater Vehicle (AUV), and has its own energy. And communicate with the mother ship through optical fiber. ARV introduces human participation and combines human and machine. Humans complete complex tasks such as identification or decision-making, and simple tasks are left to robots to solve by themselves. This type of hybrid underwater robot can extend human exploration of the ocean. The new development direction of robotics research.

Problems solved by technology

[0003] When the ARV is diving or navigating, an optical fiber micro-cable extends from the carrier end to connect to the surface end. The robot’s information upload and mission download mainly rely on optical fiber transmission, and the optical fiber micro-cable has a slender outer diameter and light weight, which is a slight load in water. Buoyancy, when the robot is deployed and sailing, the state of the optical fiber in the water is not easy to control, it is easy to be entangled with the carrier, and it is also easy to be sucked into the water flow generated by the propeller, causing communication interruption. This makes the protection of the optical fiber micro-cable very important. The water is characterized by positive buoyancy. The optical fiber is mounted on it, and an optical fiber floating package device is developed to guide the optical fiber away from the carrier for a certain distance and become a controllable state, which can not only ensure normal communication underwater but also avoid the danger of the optical fiber winding carrier.
