Abstract

The invention discloses a pipe diameter adaptive jaw and a pipe diameter adaptive underwater fixed-point operation device. The underwater fixed-point operation device includes a control mechanism, a horizontal propeller group, a vertical propeller group, an Adapt to the jaws; the pipe diameter adaptive jaws include a plurality of jaw units; these jaw units are divided into two rows, and are arranged across each other; each jaw unit includes a proximal phalanx, a middle phalanx and a Terminal knuckles; when the jaw mechanism is closed, the proximal knuckle is the first to contact the pipe, and the distal knuckle is the last to contact the pipe; when the jaw mechanism is opened, the distal knuckle is the first to leave the pipe, and the proximal knuckle is the last to leave the pipe . The pipe diameter self-adaptive claw of the present invention can adapt to different pipe diameters and has strong gripping force, and the claw cooperates with the propeller to realize the rotation of the whole device around the pipe to be operated without additional control signals and conforms to Adaptive pipe diameter, fixed-point operation, and wide range of operation objects.

Description

Technical field

[0001] The invention relates to the technical field of underwater operation devices, in particular to a pipe diameter adaptive claw and a pipe diameter adaptive underwater fixed-point operation device. Background technique

[0002] With the development and utilization of marine resources, the number of underwater operations required by humans has gradually increased, the operating environment has become increasingly complex, and the difficulty of operations has also increased. At the same time, China is a large country of ocean transportation and water conservancy construction, and a large number of ocean facilities are required. Regular cleaning or safety performance inspections. Current underwater operations are generally carried out by divers carrying operating devices. Not only are operating costs high, but life safety is difficult to guarantee. Therefore, an underwater operating device that integrates repair and cleaning is needed.
