Description

Self-adaptive rotary ROV umbilical cable bearing and connecting device
Technical Field
The invention relates to the technical field of ocean engineering, in particular to a self-adaptive rotary ROV umbilical cable bearing and connecting device.
Background
An unmanned cable-equipped underwater robot, or remote control unmanned underwater robot (Remote Operational Vehicle, ROV), is diving equipment which performs manual operation under water by using self-carried instruments and equipment, and is widely applied to the fields of inland dike detection, marine structure installation and maintenance, deep sea resource detection, marine pipeline maintenance, underwater salvage, rescue and the like. In the underwater exploration and operation by using the ROV, a water surface mother ship or a shore-based control box is connected with the underwater ROV through an umbilical cable, so that the power supply, the operation control and the data transmission of the mother ship/shore-based to the ROV are realized, and meanwhile, the deployment and the recovery of the ROV are realized. The bearing device of the ROV plays an important role in connecting the umbilical cable with the lifting structure at the top of the ROV, and leads out optical fibers and electric circuits in the umbilical cable through watertight cables and connectors to be respectively connected with the electronic cabin and the power distribution cabin of the ROV.
In deployment and recovery operations, ROVs can sway due to the effects of pitch and roll of the mother vessel, and the effects of sea storms, even unsafe operation. During deployment and recovery of the ROV, the ROV needs to traverse the water surface. ROV varies severely in load as it traverses the surface. The surrounding of the water surface is affected by severe sea conditions such as wind and wave currents, the optical-electrical composite cable can rotate due to the disturbance of the ROV by water currents, and if the number of the rotation turns is too large, the optical-electrical composite cable is at risk of being broken. In particular, in high sea conditions, deployment and recovery of ROVs is more difficult, and problems of improper recovery or equipment damage often occur. Connection of the ROV to the deck retraction system is therefore critical during deployment recovery. How to more efficiently and safely deploy and recycle ROV, protect umbilical cables from damage, is always a key challenge that plagues its use.
The underwater exploration and operation is performed, the requirements on the sailing maneuver performance and flexibility of the ROV are very high, and the ROV is generally required to have at least four degrees of freedom of movement capability of longitudinal movement, transverse movement, bow turning and vertical movement, wherein the bow turning is one of the most common movement working conditions. The ROV utilizes a vector thruster which is horizontally arranged to provide a bow turning moment to realize the bow turning motion, and drives the umbilical cable to synchronously twist through the bearing device. When the umbilical cable deployment length is short, the reverse torsional moment is large, so that the bow turning flexibility of the ROV is affected; when the umbilical cable is laid longer, the ROV can rotate the bow in a certain rotation angle range, but after the umbilical cable is beyond the rotation angle range, the torsion moment of the umbilical cable still prevents the bow from moving, if the umbilical cable is laid too long, the maneuvering flexibility and the operation energy efficiency of the ROV are affected, and even the umbilical cable can be wound, knotted or pulled with foreign matters. Especially when the rotation angle is too large or turns, serious damage to the umbilical cable is caused, and serious consequences such as reduction of electrical insulation, breakage of optical fibers and the like are caused. Meanwhile, the umbilical cable is influenced by the traction of ROV sailing motions and complex ocean currents and seawater fluctuation under water, and the cable shape and the pose state are very complex and change at any moment. At present, the bow turning angle of the ROV can be recorded only through a control system of the ROV, when the bow turning angle exceeds a preset safety threshold, an alarm prompt is sent out, the reliable operation and safety of the umbilical cable are ensured from the aspect of limiting the operation and the use of personnel, and the problems of flexibility of the bow turning of the ROV, torsion safety of the umbilical cable and the like are not solved in practice.
To this end, an adaptive rotary ROV umbilical load-bearing connection is proposed.
