Problems solved by technology

The current engineering practice usually includes retrieving the anchor chain to the deck for visual inspection, bringing the anchor chain back to shore for non-destructive testing (NTD), underwater in-situ detection by divers, and operating unmanned remotely operated vehicles (ROV). Four methods, such as position detection, are used to recover the anchor chain to the deck for visual inspection or bring the anchor chain back to the shore for non-destructive testing. It is not suitable for floating oil and gas production platforms that require permanent mooring: In order to solve the above technical bottlenecks, this patent A chain cleaning and inspection robot with hybrid drive and its operation method are proposed

Embodiment 1

[0041] see Figure 1 to Figure 4 , in Embodiment 1 of the present invention, a structural diagram of a hybrid-driven anchor chain cleaning and detection robot provided by the embodiment of the present invention includes: no less than one frame structure; a buoyancy system arranged on the frame structure for Adjust the buoyancy of the robot; the drive system is arranged on the frame structure; the drive system includes a propeller propulsion drive system and a wheel drive system; the propeller propulsion drive system is used to provide power for underwater movement; the wheel drive system is used It is used to drive the robot to move on the anchor chain; the underwater observation system is set on the frame structure to observe underwater; the cleaning system is set on the frame structure to clean the anchor chain; The system is set on the frame mechanism; and the detection system is set on the frame structure.

[0042] The frame structure is the main structure for carrying va...

Embodiment 2

[0059] The embodiment of the present invention also provides a hybrid driving anchor chain cleaning and detection robot operation method, including the following steps:

[0060] (1) Gently put the robot to a position near the mooring chain, and the robot is in a tight state at this time;

[0061] Specifically, the hook part of the robot is pulled by the crane on the mother ship, the umbilical cable is connected to the robot through the decoupler, and the robot is lightly placed near the mooring chain. At this time, the robot is in a tight state, which is convenient for the robot to work in the next step;

[0062] (2) After being deployed to a certain distance underwater, the robot is driven by the drive system and freely floats to the vicinity of the anchor chain;

[0063] Specifically, after being deployed to a certain distance underwater, a command is sent to release the decoupling device, and the robot is driven by the propeller propulsion drive system to freely float to th...

The robot comprises at least one frame structure; a buoyancy system which is arranged on the frame structure and used for adjusting the buoyancy of the robot; a driving system which is arranged on the frame structure; the driving system comprises a propeller propulsion driving system and a wheel type driving system; the propeller propulsion driving system is used for providing power for underwater movement; the wheel type driving system is used for driving the robot to move on the anchor chain; an underwater observation system which is arranged on the frame structure and is used for observing underwater; a cleaning system which is arranged on the frame structure and used for cleaning the anchor chain; an active enclasping and unfolding system which is arranged on the frame mechanism; and a detection system which is arranged on the frame structure.

Description

technical field [0001] The invention relates to the technical field of marine equipment, in particular to a hybrid-driven anchor chain cleaning and detection robot and an operation method thereof. Background technique [0002] With the development of offshore oil and gas and the utilization of marine resources, the application of floating offshore engineering equipment is becoming more and more widespread, including floating offshore platforms, FPSOs, floating wind power platforms, and floating fishery cages. The mooring positioning system is an important part of marine engineering equipment. Its function is to fix the marine engineering equipment in the operation area. The safety of the mooring system is related to the safety of marine engineering facilities. [0003] At present, the floating production, storage and offloading units in the South my country Sea, semi-submersible production and drilling platforms in service and under construction, and crude oil export termina...
