Description
Technical field
The invention belongs to marine riser facility laying technology fields, and in particular to a kind of steady pipe group vibrates anti-collision and power generation
Device and method.
Background technology
The Devoting Major Efforts To Developing of continuous growth with the mankind to demand for energy, deep water hydrocarbon resource and combustible ice becomes the mankind
Inevitable choice.Marine riser to marine oil and gas and combustible ice adopt it is defeated play a crucial role, it is by the water on sea bed
Lower well head or submarine pipeline connection are responsible for extraction fluid lift being delivered to ocean platform or Floating Production device on the water surface,
It is underwater and communication waterborne bridge.Under wave and action of ocean current vortex-induced vibration can occur for marine riser, be also easy to produce fatigue
Damage, and the complexity of abyssal environment condition and the particularity of marine riser pumped (conveying) medium keep its stress more complicated, are taken to it
Use as a servant the requirement higher of stability.
The column group structure being made of more marine risers is connection underwater well head, all kinds of platforms of submarine pipeline and sea, floats
A kind of typical arrangement mode of formula facility.Under the collective effect to outflow inside, interfered with each other between each standpipe inside column group,
So that the vortex-induced vibration characteristic of marine riser becomes increasingly complex, the unstability of direction of flow in addition, the vibration between column group
Response shows great unstability, or vibration enhances, or vibration is weak, also very likely collides, leads between each other
The destruction and failure for causing marine riser, influence the normal exploitation of marine resources, cause huge economic loss and serious environment
Pollution.The mutual collision how being effectively prevented between column group seems particularly urgent.
On the other hand, ocean new energy can be efficiently used while developing marine resources, realizes the effect of double gain
In recent years, all by extensive concern, all kinds of turbomachines are that common energy is received for the utilization of wind energy on the sea, wave energy, tide energy

The vortex to fall off, to excite standpipe(5)Vibration, standpipe(5)Anti-collision mould connected to it can be driven after vibration displacement occurs
Block moves, and makes nested telescoping tube(6)Generating period stretches;Nested telescoping tube(6)Piezoelectricity connected to it is driven when flexible
Piece circuit board(2)Movement, makes piezoelectric patches circuit board(2)Reciprocal flexural deformation occurs, generates unstable electric current, unstable electricity
It flows through conducting wire and leads to center point to disk(1)Internal rectifier(8)Rectification, and by power collector(7)It is collected, realizes hair
Electricity;Nested telescoping tube(6)When elongation, because the port screens of large and small diameter pipes limits standpipe(5)Displacement, and due to pressure
Electric piece circuit board(2)Divide to disk around center with the structure of anti-collision module composition(1)It is arranged in the form of rotating mirror-image, therefore vertical
Pipe(5)Between will not collide;Nested telescoping tube(6)When diminution, due to spring(3)Presence, limit standpipe(5)Position
It moves, it is therefore prevented that standpipe(5)Between mutual collision;Therefore, the present apparatus limits standpipe while power generation(5)Vibration displacement,
Realize standpipe(5)Collision-proof function between column group.
