Abstract
The utility model relates to an improvement of an underwater pipeline and a cable maintenance device with a aim to offer a underwater working type maintenance working cabin for the maintenance spot of the underwater pipeline and the cable. The maintenance working cabin is a thin wall cylinder shape structure without the top and bottom through the connection of three lifting oil cylinder and a submersible. The maintenance working cabin is a sealing pressure cabin, and according to the different water depth, the inner presser of the cabin can be changed. The utility model includes the maintenance working cabin, a lifting oil cylinder, a jetting impact, an aspiration system and the sealing device. The underwater working type maintenance working cabin is characterized in that: 1. the utility model can be installed with the submersible with the self-navigation capacity without the cooperation of the water surface working boat to independently work for the maintenance work of the underwater pipeline and cable; 2. The special water altering technology and the cooperation of the lifting oil cylinder can makes the maintenance working cabin deserted to the deep sea, and can do the maintenance work of the pipeline and cable embedding under a mud surface, which solves the difficult problem of the submarine pipeline and cable of offshore oilfield in our nation.
Description
Technical field
The utility model 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 purpose of this utility model is that the maintenance sites for underwater line, cable provides a kind of underwater dry-type repairing work cabin.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 utility model 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 utility model 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.
Claims (4)
1, underwater dry-type repairing work cabin, comprise workover module (6), hoist cylinder (1) and vertical spray are towards house steward (2), the level spray is towards house steward (3), level spray flushing device (4), vertical spray flushing device (5) and aspiration line (8) is characterized in that workover module (6) is processed into, the cylinder type of lower end open type, direction has two rectangular apertures in the edge, bottom, workover module (6) is installed in submersible (9) body, the upper end is evenly equipped with 3 hydraulic lifting oil cylinders (1) and is connected with the upper deck of submersible (9), between workover module (6) and the submersible (9) seal arrangement (7) is housed.
