The underwater connecting device is an important connecting device in an underwater production system and is widely applied to pipe end connection, pipe end assembly and pipe assembly of the underwater production system. Manual installation can be generally realized under water with the water depth not exceeding 200 meters, but the installation efficiency is very low, and in deep sea with the water depth exceeding 200 meters, particularly more than 500 meters, only ROV (underwater robot) can be adopted for installation. At present, the deep sea underwater connector is operated by an ROV (underwater robot), the connector is structurally provided with an ROV operation interface, the locking of the connector is realized by setting the torque of an ROV operation hand, in actual work, because the deep sea underwater operation is difficult and the observation is inconvenient, whether the connector is completely locked or not is difficult to judge under the influence of environment, if the connector is not completely locked, the operation is started, serious consequences can be generated, and the production safety is threatened. Meanwhile, the self-locking property of the driving shaft thread of the connector is poor, the connector is easy to loosen, and the connector is invalid and leaks.

The section of the cam indicating ring 4 is of an involute excircle structure with an upper end extending out, and an indicating line 14 is arranged on the extending excircle.
The beneficial effects of this hairstyle are: in the installation locking process of the underwater connector, the state of the driving shaft is checked through an observation port on the ROV interface frame, the counting of the set turns of the locking connector is realized, and the cam indicating ring is limited through a locking rod on the ROV interface frame to prevent loosening. When the maintenance is unlocked, the pressing plate is turned upwards to drive the stop rod to move upwards, the cam indicating ring is unlocked, and under the condition of unlocking failure, the driving shaft can be forcibly rotated to shear the screw 1 of the driving shaft and the cam indicating ring.
