Description

Technical Field

[0001] This utility model relates to the field of underwater robot technology, and in particular to an optical cable shaft for underwater robots. Background Technology

[0002] With the development of underwater robots, the performance requirements for supporting equipment are constantly increasing. As the energy supply and data transmission carrier for underwater robots, the functional requirements of cable reels are also becoming increasingly diversified and demanding in terms of high reliability. The problems of traditional cable reels are becoming increasingly apparent. Especially in the range of 100m to 200m cable capacity, traditional cable reels struggle to balance lightweight design and structural strength, resulting in inconvenient handling or insufficient cable capacity. The humid working environment of underwater robots places higher demands on the corrosion resistance of cable reels. Simultaneously, traditional network signal transmission is no longer adequate to meet the evolving needs of low-latency transmission of real-time information from underwater robots. Furthermore, how to conveniently control the deployment length and prevent cable tangling at the connection between zero-buoyancy cables and slip rings are also issues that need to be considered in cable reel design. Therefore, to meet these evolving needs, this paper designs a fiber optic cable reel for underwater robots, providing a new structural layout to address the aforementioned problems. Utility Model Content

[0003] This utility model relates to an optical cable reel for underwater robots, featuring a reasonable structural layout. It controls the deployment and recovery sleeve to stop via an anti-rotation pin on the right side plate, offering convenience and speed. The photoelectric conversion module inside the sleeve is located on a photoelectric module fixing plate, allowing low-latency transmission of underwater robot information via optical fiber. A slip ring connects the right side plate and the zero-buoyancy cable clamp to secure the zero-buoyancy cable, preventing cable tangling caused by the rotation of the deployment and recovery sleeve. The metal parts of the cable reel are made of hard anodized aluminum alloy, improving structural strength and corrosion resistance while reducing weight.

[0004] To address the aforementioned technical problems, this application provides an optical cable reel for an underwater robot, comprising a zero-buoyancy deployment and retrieval structure and a slip ring fixing structure. The zero-buoyancy cable deployment structure consists of a network power connection plate, a left side plate, a left side plate connector, a rotating side plate, a deployment and retrieval sleeve, a right side plate connector, a handle connecting shaft, a right side plate, a handle, a solid tube, a zero-buoyancy cable, and an anti-rotation pin. The handle engages with the handle connecting shaft; when the handle rotates, it drives the rotating side plate, the left side plate connector, and the right side plate connector. Both ends of the solid tube are fixed to the left and right side plates, and simultaneously engaged within the elongated grooves of the left and right side plate connectors, thus securing the solid tube. Rotating together with the handle causes the deployment sleeve to rotate. When the length of the zero-buoyancy cable meets the operational requirements, the anti-rotation pin fixed to the right side plate can be pulled to lock it into the circular opening of the rotating side plate, facilitating the control of the cable shaft deployment. The slip ring fixing structure consists of a slip ring fixing component, a photoelectric slip ring, a slip ring connecting left side plate, a slip ring support shaft, a photoelectric module fixing plate, a photoelectric conversion module, a slip ring connecting right side plate, a zero-buoyancy cable clamp, and a slip ring. The photoelectric conversion module is located on the photoelectric module fixing plate, connected to the slip ring on the left and to the zero-buoyancy cable on the right. The zero-buoyancy cable passes through the central circular hole of the slip ring connecting right side plate and is fixed by the zero-buoyancy cable clamp.

[0005] As a preferred embodiment of this solution, the signal conversion is achieved through a photoelectric conversion module, thereby realizing low-latency information transmission.

[0006] As a preferred embodiment of this solution, the photoelectric fixing plate is provided with a glue-receiving groove to facilitate the vulcanization operation of the zero-buoyancy cable.

[0007] As a preferred embodiment of this solution, the zero-buoyancy cable is fixed by connecting the right side plate with a slip ring and the buoyancy cable clamp, thus avoiding cable tangling caused by the rotation of the deployment and recovery sleeve.

[0008] As a preferred embodiment of this solution, the right side plate is equipped with an anti-rotation pin, which can control the rotation and stopping of the deployment and recovery sleeve, thereby controlling the extension length of the zero-buoyancy cable.

[0009] As a preferred embodiment of this solution, the network port power connection board supports aviation socket installation to adapt to the relatively humid working environment of underwater robots.

[0010] In a preferred embodiment of this solution, the metal material is hard anodized aluminum alloy, which has high strength and light weight, thereby increasing cable capacity, while also possessing a certain degree of corrosion resistance, making it suitable for humid working environments. The zero-buoyancy cable can provide power to the underwater robot while transmitting information to the control terminal. It can also be used for the recovery of the underwater robot.

[0017] This utility model provides an optical cable reel for underwater robots with a reasonable structural layout. It controls the deployment and recovery sleeve to stop via an anti-rotation pin on the right side plate, offering convenience and speed. The photoelectric conversion module inside the sleeve is located on a photoelectric module fixing plate, allowing low-latency transmission of underwater robot information via optical fiber. A slip ring connects the right side plate and the zero-buoyancy cable clamp to secure the zero-buoyancy cable, preventing cable tangling caused by the rotation of the deployment and recovery sleeve.

The handle 11 cooperates with the handle connecting shaft 9. When the handle 11 rotates, it drives the rotating side plate 6, the left side plate connector 5, and the right side plate 10 connector 8. The two ends of the solid tube 12 are fixed to the left side plate 4 and the right side plate 10, and simultaneously locked in the elongated grooves of the left side plate connector 5 and the right side plate connector 8, so that the solid tube 12 and the handle 11 move together. The rotation causes the deployment sleeve 7 to rotate. When the length of the zero-buoyancy cable 13 meets the operational requirements, the anti-rotation pin 14 fixed on the right side plate can be pulled to lock it in the circular opening of the rotating side plate 6, thus conveniently controlling the cable shaft deployment to stop. The slip ring fixing structure 2 consists of a slip ring fixing component 15, a photoelectric slip ring 16, a slip ring connecting left side plate 17, a slip ring support shaft 18, a photoelectric module fixing plate 19, a photoelectric conversion module 20, a slip ring connecting right side plate 21, and a zero-buoyancy cable clamp 22. The photoelectric conversion module 20 is located on the photoelectric module fixing plate 19, connected to the slip ring 16 on the left and to the zero-buoyancy cable 13 on the right. The zero-buoyancy cable 13 passes through the central circular hole of the slip ring connecting right side plate 21 and is fixed by the zero-buoyancy cable clamp 22.

[0020] In practical applications, the photoelectric conversion module 20 is used to achieve signal conversion and realize low-latency information transmission.

[0021] In practical applications, the photoelectric fixing plate 19 is provided with a rubber receiving groove to facilitate the vulcanization operation of the zero buoyancy cable 13.

[0022] In practical applications, the zero buoyancy cable 13 is fixed by connecting the right side plate 21 and the buoyancy cable clamp 22 via a slip ring, thereby preventing the zero buoyancy cable 13 from getting tangled due to the rotation of the deployment and recovery sleeve.

[0023] In practical applications, the right side plate 10 is equipped with an anti-rotation pin 14, which can control the rotation and stop of the deployment and recovery sleeve 7, thereby controlling the extension length of the zero buoyancy cable 13.

[0024] In practical applications, the network port power connection board 3 supports the installation of aviation socket 23 to adapt to the relatively humid working environment of underwater robots.

[0025] In practical applications, the underwater robot's fiber optic cable reel is made of hard anodized aluminum alloy, which boasts high strength and light weight, thereby increasing cable capacity. It also possesses a certain degree of corrosion resistance, making it suitable for humid working environments. The zero-buoyancy cable 13 can provide power to the underwater robot while simultaneously transmitting information to the control terminal. It can also be used for the recovery of the underwater robot.
