Active flap type anti-loosening mechanism for underwater torque interface

Abstract

The present invention provides an underwater torque interface movable flap type anti-loosening mechanism, wherein the base is connected to the anti-loosening seat, fixed in position in space, and integrated with the connected underwater components. After the handle, anti-loosening cover, driving ring, flap, and fixed ring are installed, they are placed in the anti-loosening seat as an integral structure, the handle rotates clockwise to drive the anti-loosening cover to rotate, the anti-loosening cover is connected to drive the driving ring through screws, the inner side of the driving ring is provided with a driving column installed in a non-standard arc track inside the flap, and moves along the non-standard arc track to make the flap retract inward, and the clamping teeth squeeze the square head of the torque interface to reach the final anti-loosening position. Then remove the screws between the anti-loosening cover and the driving ring, the ROV rotates the handle to drive the anti-loosening cover to complete the threaded connection with the driving ring and the anti-loosening seat, the lower end face of the anti-loosening cover contacts the upper end face of the flap to generate friction, and finally the anti-loosening cover and the driving ring are connected again with screws, all the parts are fixed in space, and the anti-loosening is completed.
