Description
Technical field
The present invention relates to a kind of submarine pipeline plugging devices, belong to seabed operation engineering device technique field.
Background technology
People to the R and D of ocean oneself through thering is a very long time, wherein seabed crude oil and gas extraction to be
The most important thing in ocean development engineering.But the complex environment and condition of high voltage and crude oil, natural gas itself due to seabed
The influence of speciality brings a degree of corrosion and destruction to sea-bottom oil-gas transport pipeline.Especially in deep ocean work, with
The increase of the complexity and pipeline usage time of marine environment, the damage of offshore oilfield pipeline even results in the feelings of oil and gas leakage
Condition it occur frequently that, so when seabed transporting petroleum and natural gas pipeline once by irresistible power destroy or itself fatigue by
Damage, it will lead to great economic loss and the pollution of environment is destroyed.Therefore, it is repaired present in submarine oil transport pipeline
Just become the important link that has to face and solve with test problems.Submarine pipeline plugging device is exactly to be sent to pipeline
A kind of device that suitable location blocks pipeline, to complete repair and the detection operation of pipeline.
Submarine pipeline repair has two methods of pipe clamp repair and impaired pipeline section repair and replacement.Pipe clamp repair is to be directed to small area
Small hole leaking, can be repaired in the pipeline external surface of damage, but when occur large area Crack Leakage either become
Such method can not be just applied after shape, what is generally taken is that excision damaged pipe is replaced with new pipe.Pipe clamp repairs, that is, exists
Impaired pipeline external surface sets up repair pipe clamp, can be divided into according to its type of attachment：It is bolted form and welding form；By
Damage this method for maintaining of pipeline section repair and replacement is to be determined according to the state of its free pipeline section and pipeline section to be substituted, and is generally divided into
2 points：First, connector repairs, mechanical connector is installed at expansion bends pipe nipple both ends；Second is that welding repair, the installation of expansion bends both ends
Sleeve is welded and is sealed.
Intelligent blocking technology has many advantages, such as that small, light-weight, high degree of automation and closure maximum pressure are big, than passing
System structurally and functionally has the plugging device of pipeline tapping formula the advantage of bigger.High-voltage intelligent plugging device is in pipeline oil in pipe
The effect of gas medium pressure is lower to be moved forward, and is opened hydraulic system by ultralow frequency electric impulse signal and blocked or solve come realization device
The action of envelope, easy to operate, high degree of automation.The device is suitable for the isolation, closure of oil gas leak source inside oil-gas pipeline, turns
A variety of situations such as connect and repair.
Imderwater cutting punching plugging device equipment to pipeline mainly for being brought due to oil inside pipeline or natural gas
The case where corrosion damage either causes canal depression to be bent due to other external force.Its main feature is that high degree of automation, technique is first
Into no closed machine cuts of flame, safe and reliable pollution-free, need not stop production can complete the plugging holes operation of pipeline.
Maintenance fixture is that two symmetrical lobes of clamp body are closely joined together using bolt, is a kind of pipeline external repair
Mode, and by clamp body transmitting thrust, using this thrust can the place of pipe leakage formed one it is closed very
Good Wrap device is completed to the closure at pipe leakage.This fixture have the characteristics that it is easy to maintenance it is quick, expense is low, it is suitable
, pipe operations pressure rating smaller for piping failure and safe class require relatively low situation.
Invention content
Present invention mainly solves the technical issues of：Inefficiency, sealing effect are blocked for existing submarine pipeline plugging device
The problem of fruit difference, the present invention provides a kind of submarine pipeline plugging devices.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention：
A kind of submarine pipeline plugging device, including plugging device, jackshaft and motor, the plugging device outermost layer is floating
Plate, kickboard are internally provided with voussoir, are connected using sunk screw between kickboard and voussoir, and voussoir is internally provided with cone machine
Structure, cone mechanism right side are provided with limited block, are flexible seal ring on the right side of limited block, cone structure is internally provided with voussoir, institute
The jackshaft stated runs through plugging device, and one section of jackshaft is fixed in kickboard, and the other end of jackshaft is provided with screw thread, intermediate
The axis other end is connected by screw thread with driving mechanism, and driving mechanism connects motor.
A kind of application process of submarine pipeline plugging device is：Pipeline plug is put into pipeline, when carrying out closure operation
Motor drives driving mechanism rotation, since, using being threadedly coupled, driving mechanism rotation makes centre between jackshaft and driving mechanism
Axis moves right, and the mutually right movement of jackshaft drives kickboard to move right, and the flexible seal ring on the right side of limited block is under squeezing action
Expansion is to blocking pipeline, when plugging device moves right the baffle that limit back wedge touches right side, voussoir to
Left movement pushes cone mechanism to move downward, and cone mechanism urges voussoir, voussoir makes kickboard move outward, kickboard and pipeline
Inner wall is in contact that plugging device is made to be secured firmly to inside pipeline.
The flexible seal ring is made of rubber material.
It is provided with gear between the motor and driving mechanism.
The beneficial effects of the invention are as follows：
（1）A kind of submarine pipeline plugging device is devised in the present invention, is used motor as driving device in the present invention, is passed through electricity
Machine drives driving mechanism rotation, driving mechanism by the way of being threadedly coupled, to make jackshaft in driving mechanism function with jackshaft
Lower freedom moves right to the left, to be blocked to pipeline, improves the closure efficiency of plugging device in this way, and
The active force that motor drives jackshaft movement to generate is big, can realize the tight seal to pipeline.
（2）Sealing device includes flexible seal ring and kickboard in the present invention, and flexible seal ring is due to being sealed pipeline
It prevents from revealing, kickboard prevents plugging device in pipeline internal motion, reduce sealing for plugging device to be fixed on inside pipeline
Effect.
