the utility model provides a special folded cascade ROV nut of ROV-H type shackle, includes ROV nut main part, four reservation grooves have been dug to the upper end of ROV nut main part, two nut stands of upper end fixedly connected with of ROV nut main part, two the side threaded connection of nut stand has four mounting screw, two the nut stand is respectively through four mounting screw threaded connection in the upper end of ROV nut main part, four mounting screw threaded connection is in the inner wall of four reservation grooves respectively, two the nut stand lean on the near-end mutually and all rotate to run through rivet, two the close to end fixedly connected with nut handle mutually of rivet.

As the utility model discloses further scheme again, two the nut stand lean on the near-end mutually and all rotate and be connected with friction pad, two friction pad overlaps respectively and locates the surface of two rivets.

As the utility model discloses further scheme again is located the left the side fixedly connected with stopper of nut stand.

As the utility model discloses further scheme again, the middle part of nut handle is the cylinder.

As the utility model discloses further scheme, two the chamfer is all done to the upper end of nut stand and stopper.

As a further proposal, the lower end of the limiting block is higher than two rivets.

Compared with the prior art, the beneficial effects of the utility model are that:

1. through the four mounting screws, the two nut stand columns are respectively fixed at the upper end of the ROV nut main body by the four mounting screws to be kept stable, the tightness between the two nut stand columns and the ROV nut main body is kept after the nut handle is gripped by an underwater manipulator, and the ROV nut main body can be easily driven to rotate by the manipulator gripping the nut handle to be screwed into the bolt.

2. Through the stopper that sets up, after accomplishing the twist operation of ROV nut main part, the manipulator rotates 90 with it, and the side of nut handle supports the lower extreme that the stopper made it can not the skew angle again to give away the space that the handle occupy, make the manipulator can continue through swivel nut handle, carry out the locking of the locking mechanical system of ROV nut main part.

3. Through two friction pads that set up for the nut handle is when changing the angle, and two friction pads link up the end of keeping away from mutually that two near ends of rivet are close to mutually with the nut handle, increase frictional force between the two, make it keep stable state under no external force interference, prevent that the nut handle from taking place to deflect along with rivers are undulant, influence the snatching of gripper.

The utility model discloses in, through the rotation of the easy drive ROV nut main part behind the robot gripping nut handle, after accomplishing the twist operation of ROV nut main part, operation manipulator rotates the nut handle 90 towards the outside to let out the space that the nut handle occupy, continue to pass through swivel nut handle, carry out the locking mechanism's of ROV nut main part locking mechanism, can solve effectively and carry out the problem that can take place to interfere with robot's manipulator under water when final ROV nut main part locking mechanism operation.
