Underwater cable connector with handling system and actuator
A recently granted patent (Publication Number: US11677180B2) describes a handling system for underwater cables. The system includes a connection housing, a handling bar, and an actuator. The cables enter the connection housing parallel to each other and parallel to a first direction. The handling bar is connected to the connection housing by a hinged link, allowing for movement perpendicular to the first direction. The actuator is responsible for moving the connection housing between a supine storage position and an upright position for submersion/retrieval. This movement is achieved by pivoting about the axis of the hinged link on the handling bar.
The handling system also features a curved ramp, which includes a ramp portion for the connection housing and multiple curved guide portions of the hinged link. These guide portions are located on opposite sides of the ramp portion. The link itself consists of opposing symmetrical protruding parts of the connection housing.
The handling bar has a U-shape and is engaged on either side of the connection housing. The branches of the handling bar have connecting ends that are hinged on the connection housing by the link. The handling bar can be connected to at least one handling cable. Additionally, the connection housing can be equipped with one or more removable ballast masses.
The patent also mentions the use of this handling system in a marine platform.
In summary, the granted patent describes a handling system for underwater cables that allows for efficient submersion and retrieval. The system includes a connection housing, a handling bar, and an actuator. The movement of the connection housing is facilitated by a curved ramp and a hinged link. The handling bar can be connected to handling cables, and the connection housing can be equipped with removable ballast masses. This system can be used in marine platforms.
