Description
Technical field
The invention belongs to sea-bottom oil-gas pipeline safety monitoring field, be specifically related to one and spread for seabed adjoining pipeThe optical cable fixing device of cable.
Background technology
Sea-bottom oil-gas pipeline is the defeated important component part with accumulating of marine oil and gas collection, belongs to that investment is large, windThe offshore oil facility that danger is high is being brought into play significant role, sea-bottom oil-gas pipe in marine oil and gas resource exploitationWhether normal safety in production and the operation that is related to offshore oil and gas field in road.
Due to the defeated particularity of marine oil and gas collection, sea-bottom oil-gas pipeline presents and land oil in-serviceThe different characteristics of feed channel: first, sea-bottom oil-gas pipeline is subject to the complicated marine environment such as wave and ocean currentThe effect of load, in particular cases also will consider the effect of earthquake and tsunami; Secondly, due to sea-bottom oil-gasImportant function in geographical position and its oil exploitation at sea that pipeline is special, once there is pipe leakage,The economic loss causing and harm are all that terrestrial pipeline is incomparable. But, again due to sea-bottom oil-gas pipeParticularity and the complexity of road on geographical position, the leakage of sea-bottom oil-gas pipeline is difficult to avoid completely.
Sea-bottom oil-gas pipeline leaks the tremendous influence and the serious consequence that cause and is mainly manifested in following two sidesFace: 1, cause that oil gas field stops production or the underproduction, brings huge economic loss; 2, cause serious oceanPollute and the huge wasting of resources. Occurred in the last few years a lot of because sea-bottom oil-gas pipeline leaks both at home and abroadThe marine pollution incident causing. Therefore, the Safety production questions of sea-bottom oil-gas pipeline obtains ocean, various countries workThe strong interest of journey circle. China's sea-bottom oil-gas pipeline lacks safety monitoring means accurately and effectively for a long time,For a long time in " monitoring vacuum " state. Because the Integrity Management of submarine pipeline is asset integrity managementImportant component part, how to fill up the present situation of submarine pipeline " monitoring vacuum ", become urgently to be resolved hurrilyTechnical task.
At present, the existing Distributed Optical Fiber Sensing Techniques that uses is monitored the leakage situation of terrestrial pipelineApplication case, but technique is not applied to submarine pipeline, is mainly because submarine pipeline leavesWhen offshore section turns to submarine laying, optical cable is difficult to pipeline coordination, in the same way, parallel being strapped in together.
Summary of the invention

Detailed description of the invention
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples,And coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-3, a kind of optical cable fixing device for seabed adjoining pipe paving cable, comprises clip 1, cardHoop by ring-type band 11 with realize band and lock the securing member 12 being connected and form. On the outer ring surface of bandAt least be installed with an optical cable keeper 2, optical cable keeper and band are connected by welding manner.Also comprising can be with any optical cable keeper by the detachable optical cable fastener 3 being connected of screw. At optical cableThe faying face position of keeper and optical cable fastener is provided with optical cable mounting groove.
In said structure, be further provided with in the faying face position of optical cable keeper and optical cable fastener to form and insertThe concavo-convex location structure that assembling is closed. Concavo-convex location structure has facilitated the location of optical cable keeper and optical cable fastenerConnect. Described concavo-convex location structure is fixed by being fixed on the locating dowel 4 on optical cable fastener end face and being located at optical cableThe slot 21 matching on the corresponding end face of position part forms, and described locating dowel is made up of magnetic material. Optical cable is fixedBetween position part and optical cable fastener, adopt the above-mentioned magnetic location structure being formed by locating dowel and slot, realizedFrom finding suction location, can reduce greatly the difficulty of diver's underwater construction operation, significantly reduce and doIndustry cost and shortening activity duration, the while has also alleviated diver's homework burden. Above-mentioned locating dowel is with slottingGroove fit structure can adopt column fit structure, arcuation fit structure etc. In the present invention, described locationPost and slot further preferably adopt V-type fit structure. V-type fit structure has facilitated locating dowel to be inserted intoIn slot.
