Technical field
The present invention relates to a kind of protection dress of flexible pipe used during mechanical device, particularly a kind of offshore oil exploration and exploitation
Put, belong to mechanical engineering technical field.
Background technology
Currently, the exploration and development of Marine oil and gas resource just turns to deep-sea by shallow sea.The step of Marine oil and gas resource is developed master
Including：Explore, be drilled well, production, accumulating and refinery etc..How the marine oil and gas obtained by drilling is operated to land from well head
Ground, such as the oil gas in subsea production system or floating production system is transported to land, during being offshore and gas development
One big key issue.Flexible pipe is just fast at present with the incomparable anti-bending strength of conventional steel pipe because of its distinctive composite construction
Speed development and application.However, the working environment of flexible pipe is extremely complex, except the tension and compression needed for work, torsion and bending load, go back
Bear the influence that the uncertain load such as wave, ocean current and installation and temperature difference etc. are brought.In addition, the flexible pipe close to the water surface may be used also
The impact of trash ice and floating object can be born so that flexible pipe surface structure damage and failure, and then destroy flexible tube structure.Cause
This, need to design a kind of protection device to be avoided or reduce influence caused by shock loading.
The protection device (US 7927041B2) for being related to flexible pipe at present is the taper formed by rigid material
Thing (being similar to cone) or cylindrical shell are formed by connecting and (connected by chain).However, these component qualities are larger, limited
Well head space inconvenience installation and change.For the deficiency of existing structure, how designing one kind can avoid or reduce floating object from rushing
The ocean flexible pipe protection device hit while overcome these insufficient again, which becomes, attaches most importance to.
The content of the invention
It is an object of the invention in order to reach above-mentioned target, spy proposes a kind of ocean flexible pipe protection device.
To reach above-mentioned purpose, the present invention, which solves the technical scheme that this technical problem uses, is：
A kind of ocean flexible pipe protection device, mainly by iron chains, suspension joint, pull bar, protection network, transition joint, righting
Joint and righting rubber ring composition, it is characterised in that：The upper end of iron chains is hung on the hanger of hull, its lower end and suspension joint
Connection；The suspension joint is connected through a screw thread with pull bar upper end；Connected between the pull bar and other pull bars by transition joint
Connect；The lower end of the righting joint and pull bar is connected through a screw thread；The righting rubber ring and righting joint use sulfuration process
It is fixedly connected；The protection network is fixedly connected with pull bar；There is 4-8 each cross section of the ocean flexible pipe protection device
Root pull bar is in parallel and these pull bars are distributed uniformly and circumferentially；The structure that the pull bar is formed with protection network is cylindrical in shape, flexible
Ocean flexible pipe protection device of the pipe through tubular.
A kind of described ocean flexible pipe protection device, it is characterised in that external diameter of the internal diameter of righting rubber ring than flexible pipe
Big 6-10 millimeters；The pull bar upper and lower ends screw thread it is oppositely oriented, i.e., lower end screw thread is left-handed when threaded upper ends are dextrorotation,
When threaded upper ends are left-handed, then lower end screw thread is dextrorotation；Transition joint both ends screw thread it is oppositely oriented.
The invention has the advantages that：(1) using pull bar and the combination unit of protection network, construction weight in the present invention
Small, rigidity is also smaller；(2) connected using the combining structure of more piece protection network and pull bar, the flexible pipe that can be protected as needed
Length-flexible adjusts the quantity of combining structure.

Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As Figure 1-Figure 4, a kind of ocean flexible pipe protection device, mainly by iron chains 3, suspension joint 4, pull bar 5, protection
Net 6, transition joint 7, righting joint 9 and righting rubber ring 10 form, it is characterised in that：The upper end of iron chains 3 hangs on hull 1
On hanger 2, its lower end is connected with suspension joint 4；The suspension joint 4 is connected through a screw thread with the upper end of pull bar 5；The pull bar 5
It is connected between other pull bars 5 by transition joint 7；The lower end of the righting joint 9 and pull bar 5 is connected through a screw thread；It is described
Righting rubber ring 10 is fixedly connected with righting joint 9 using sulfuration process；The protection network 6 is fixedly connected with pull bar 5；The sea
Each cross section of foreign flexible pipe protection device 11 has 4-8 roots pull bar 5 in parallel and these pull bars 5 along the circumferential direction uniformly divide
Cloth；The structure that the pull bar 5 is formed with protection network 6 is cylindrical in shape, and flexible pipe 8 passes through the ocean flexible pipe protection device 11 of tubular.
A kind of as shown in figure 4, described ocean flexible pipe protection device, it is characterised in that the internal diameter ratio of righting rubber ring 10
The big 6-10 millimeters of external diameter of flexible pipe 8.
As shown in figure 1, the upper and lower ends screw thread of pull bar 5 is oppositely oriented, i.e., the lower end spiral shell when threaded upper ends are dextrorotation
Line is left-handed, and when threaded upper ends are left-handed, then lower end screw thread is dextrorotation；The both ends screw thread of transition joint 7 it is oppositely oriented.
As shown in figure 5, the ocean flexible pipe protection device 11 is installed on the lower section of hull 1.Due to trash ice or floating owner
To be located at several meters below seawater surface or surface of position, when trash ice or floating object shock flexible pipe (8), ocean flexible pipe is protected
