Description
Technical field
The utility model relates to a kind of system of protecting cable pouring weight for discharging seabed.
Background technique
Because some seabottom geology is harder; or there is pipeline the situation such as to hand over more extra large cable or submerged pipeline punching cannot be buried to sea bed; exposed extra large cable or submerged pipeline are very easily because various Activities of Oceans produce fault; therefore; adopt the mode of cement block of covering on the extra large cable of failing to bury underground or submerged pipeline, can reach extra large cable that protection fails to bury underground or the object of submerged pipeline.
In conjunction with Fig. 1, traditional mode that covers cement block on extra large cable or submerged pipeline is: first by cement block (conventionally specification be 6000mm × 2000mm × 200mm) colligation on bandage, on bandage, there are multiple bandages to buckle, bandage is buckled to carry on fixed frame 1, thereby realize being connected and fixed of cement block and fixed frame 1, then by the A type frame on lash ship 2 or crane 3, the framework with cement block 1 has been discharged into seabed together.By the time cement block is pressed in extra large cable or submerged pipeline 4 completely above or highly meets after release conditions, use underwater robot 5 to pull the releasing mechanism on fixed frame 1, bandage on bandage is buckled and is departed from fixed frame 1, and cement block has just been applied on extra large cable or submerged pipeline 4; Recycling A type frame or crane 3 lift by crane fixed frame 1, are finally recovered on ship.Discharge in process whole, on fixed frame 1, there is no power plant, self do not trigger the device of releasing mechanism yet, therefore the last action discharging need to be completed by underwater robot 5, and be tied with the fixed frame 1 of cement block and underwater robot 5 and be very easily subject to the impact of current, thus position that need to the mobile fixed frame 1 of mobile lash ship 2, and need underwater robot 5 mate-assist, monitoring fixed frame 1 is underwater dynamically, completes and discharges operation.In addition, on fixed frame 1, do not possess camera and beacon yet, cannot accurately determine self-position, thus the camera that need to use underwater robot 5 determine mutual alignment relation and determine the position of fixed frame 1 and cement block, process is very numerous and diverse.But because underwater robot 5 is with multiple propulsion devices, it is very large on the impact of underwater visibility that blade rotates the seabed silt taking up, unavoidably must have influence on the precision of finally discharging cement block.See therefrom, the trivial operations that the whole process of discharging relates to, department is numerous, still can not accurately control the position that cement block discharges.
If adopt above-mentioned dispensing mode to discharge pouring weight at 80 meters of depth of water places, depend on different sea situations and underwater visibility, conventionally discharge and once need 3-6 hour consuming time., discharge in process the whole of 3 hours used times as example taking situation the most smoothly, need to spend the position that about 40 minutes utilize underwater robot and beacon adjustment to discharge framework; After pouring weight is applied to sea bed, also need underwater robot inspection finally to discharge position, this process will expend again approximately 30 minutes, after all inspections, data all meet customer representative's requirement, just can reclaim fixed frame, and the pouring weight carrying out next time discharges work.Be subject in limited time and work as sea situation, underwater robot has to wait for approximately 90 minutes until visibility reaches after certain standard, just can carry out final inspection.As can be seen here, for traditional framework that discharges, the coordinative construction of underwater robot, wait for that the various complementary operations such as visibility (the underwater robot thruster silt of playing is very large on visibility impact) have accounted for approximately 40% of total engineering time.It should be noted that these times do not comprise the time that lash ship moves, mobile lash ship needs multisystem to coordinate, and by the dynamic positioning system on ship (referred to as data process system), changes the position of lash ship by multiple thrusters.Again due to the accuracy limitations of data process system, often expend the plenty of time but still not reach expected effect.
