Abstract
The invention relates to an improvement on the underwater tube and cable maintainer, especially providing an underwater dry maintain cabin. Wherein, it is in thin-wall cylinder structure, without top and bottom, which is connected to the diver via lifting cylinder; said cabin is a sealing pressure cabin, whose pressure can be adjusted according to the water depth. And it is formed by maintain cabin, lifting cylinder, ejection system, pump system, and sealing device. The invention is characterized in that: it can be mounted on the diver with self navigation ability, to process the maintenance without working ship; and said cabin can dive into sea bed, via the lifting cylinder, to maintain the embedded cable and tube.
Description
Technical field
The invention belongs to underwater line, cable maintenance apparatus.
Background technique
At present external offshore oilfield mostly is enclosed sea territory or big lake greatly, foundation of sea floor is all more solid, and general pipeline all adopts gravity prefabricated, and pipeline is directly put into seabed, not pre-buried.Therefore utilize the submarine diving car abroad usually,, adopt technology such as leakage field to visit in managing and leak by the radar fix system, as finding the pipeline breakage, or whole section replacing, or adopt buoyancy tank to sink to the seabed, and water in the buoyancy tank is got rid of, personnel enter to carry out the pipeline repairing work.Said method all needs cooperatively interacting of water craft and submersible.And at present underwater line, the cable in oil field, China shallow sea adopt filling-up method to lay usually, and buried depth is all more than 1m, and the sea situation complexity, and ocean current washes away, excavate, to empty phenomenon serious.Adopt above-mentioned external method to carry out pipeline, cable maintenance operation, economically with construction effect on not very good.
Summary of the invention
The objective of the invention is provides a kind of underwater dry-type repairing work cabin for the maintenance sites of underwater line, cable.By vertical, level spray flushing system, suction system water-bed silt is sprayed and to dash suction, expose and just can carry out maintain and replace after being embedded in the following underwater line of mud face, cable.
Underwater dry-type repairing work cabin is processed into the cylinder type of upper and lower end open type, direction has two rectangular apertures in the edge, bottom, workover module is installed in the diving body, the upper end is evenly equipped with 3 hydraulic lifting oil cylinders and is connected with the upper deck of submersible, between workover module and the submersible seal arrangement is housed.Vertical spray is installed towards the spray of house steward and level towards house steward and be connected respectively to the vertical spray flushing device and the level spray flushing device of workover module bottom in workover module.Suction pump is housed in submersible, is connected to the aspiration line in the workover module.In the workover module upper side locking device is housed.
Good effect of the present invention is that it can be installed on the submersible with the ability of navigating certainly, and the cooperation that need not the water-surface working boat oceangoing ship can be carried out the maintenance operation of underwater line, cable independently.More outstanding advantage is, can insert below the water-bed mud face by its unique water replacement technique workover module, and anhydrous working space of band pressure of silt formation is dashed, aspirates out in spray, thereby can carry out maintenance operation to underwater line, the cable of imbedding below the mud face, be applicable to the production status of China's offshore oilfield more.

Embodiment
Now the invention will be further described in conjunction with Figure of description 1:
1, workover module heavy cabin operation:
After the submersible 9 that underwater dry-type repairing work cabin is housed being reached the predetermined work position and sitting location, the end, begin heavy cabin operation.At first opening positioning device 10 makes workover module be in free state, open vertical spray in the submersible 9 again towards pump, high-pressure water flow dashes through vertically spraying vertically to spray to vertical spray flushing device 5 towards house steward 2, after treating 6 times slotting certain depths of workover module, the level of opening again in the submersible 9 is sprayed towards pump and suction pump, high-pressure water flow sprays flushing device 4 through the level spray towards house steward 3 to level, make the silt of work chamber bottom form the mud eddy flow, and by outside the suction piping 8 discharge work chambers 6.Inflation in seal arrangement 7 simultaneously, annular seal space.Along with the mud that has been stirred is drawn out of out of my cabin, under the cooperation of the hoist cylinder 1 at workover module top, workover module 6 sinks gradually.After treating down to be inserted into predetermined depth, close vertical, level and spray towards pump, injecting compressed air makes cabin external and internal pressure maintenance balance in workover module 6.After treating that suction pump pumps the water in the workover module, just formed a band and pressed anhydrous working space.The operating personnel just can enter maintenance lock behind the decompression chamber petroleum pipeline or cable are carried out maintenance operation by adding.
2, work chamber rises the cabin operation:
After maintenance operation was finished, workover module was withdrawn the scene.At first the operating personnel discharges the pressurized air in the seal arrangement 7 by adding decompression chamber decompression recession from workover module.Open hydraulic system then, workover module 6 be promoted to operational configuration by hoist cylinder 1, last locking and positioning device 10 with workover module 6 positioning and lockings after, the submersible floating is left the job site.
