Description
Technical field
The utility model relates generally to technical field of wind power generation, specifically, relates to a kind of offshore wind turbine and levelling device thereof.
Background technology
Compared with land blower fan, the weight of offshore wind turbine is larger, thus need larger erection equipment, and land large-scale erection equipment can not come into operation, installation vessel can only be relied on to install, expensive.Current offshore wind turbine mounting means mainly comprises partial installation and offshore integral is installed.During installation, by blower fan local or integral installation good after, then blower fan is connected to blower foundation.
Offshore wind turbine foundation, before lifting fan, installs leveling all, is mounted to by blower fan tower barrel after on basis, because the weight of blower fan itself is comparatively large, the relative position on basis may be affected, therefore need again to call special level device, again leveling, adds installation cost.
Aforementioned whole installation process comprises two stages: leveling, blower fan tower barrel are installed with leveling again after the connection of basis in basis.Owing to experiencing two leveling stages, reduce installation effectiveness.
In addition, the situation of offshore wind power foundation run-off the straight mainly contains two kinds: one is that another kind is in use in construction sinking operation process.Leveling operation when sinking to for foundation construction, mainly contains following several mode:
1) act on vertical load in tilting position, basis: when after basic run-off the straight, increase load in tilting region, basic top, load manner can be building stones, the discarded building concrete etc. becoming case, tilts end sinking to impel.
2) utilize marine excavator to carry out excacation to earth below tilting position, dig up a part of earth, with the leveling work of optimized integration.
3) utilize pressure itself to apply negative pressure leveling: the method is only applicable to the structure that basic internal has enclosed environment (point storehouse), by the different point storehouse pressure in basis, form the working environment that negative pressure is sunk, realize leveling.
4) high pressure gaslift is broken ground: the side wall lower ends on basis applies high pressure gaslift and breaks ground, and to tilting position, basis, in barrel, arrange pipeline of blowing sand, conveying high-pressure gas causes gas explosion effect to inside soil body, blows the soil body open, realizes leveling.
For first kind of way, vertical magnitude of load is difficult to determine, process medium dip situation of change is also difficult to control; For the second way, mining clay side's amount is difficult to control, and easily produces to dig to cause another side to tilt more; For the third mode, can only have interior chamber structure for basis, negative pressure value is wayward; For the 4th kind of mode, need pre-configured pipeline, increase additional workload.
Leveling operation when tilting for basic use procedure, mainly contains following several mode:
1) slip casting leveling: heavy end slip casting under the foundation, realizes leveling.
2) cylinder inner high voltage inflation leveling: the method only has for basic internal closes interior chamber structure, and contrary with negative pressure sinking operation, the method is that increase pressure in cylinder, lift-up pressure overcomes gravity, frictional force, is ejected on basis to the inflation of silo inner high voltage.
For aforementioned first kind of way, be only adapted to relatively weak soil property, and complicated operation, increase extra cost; For the aforementioned second way, being only adapted to basis has interior chamber structure, and the bad control of pressurising force value.
