The tower (100) includes a plurality of tower segments (262,264), wherein each tower segment includes a first interface (330), and a second interface (340), wherein a first interface of a first tower segment is bonded to a second interface of a second tower segment by an adhesive composition (435).
Description
Technical field
[0001] the wind tower that uses with wind turbine of the application's relate generally to, and more specifically, relate to the wind tower that can use adhesive that a plurality of parts of wind turbine tower are combined and assemble.
Background technique
[0002] wind turbine is being used for producing electric energy progressively.At least some known wind turbines comprise wind turbine tower, be arranged in the nacelle (nacelle) on the wind turbine tower and be supported on the rotor of nacelle by axle.In at least some known wind turbines, wind turbine tower comprises three tower parts: top section, middle part part and base section.Each tower part is made by one to ten or more single jar shape section, and these sections are typically welded together.
[0003] in known wind turbine tower, top section is farthest a part overhead, and the base section kiss the earth.The middle part part is extended between top section and base section.Each wind turbine tower partly provides the part with strong structural load paths from the turbo machine to ground.In addition, the wind turbine tower part any mechanical inner member and/or the electric inner member that also may need system provides support.Known wind turbine tower part connects by welding, bolt and/or other known machanical fastener assembly connects together to form wind turbine tower.Especially, welded together the jar shape section of each wind turbine tower part to form each independent wind turbine tower part, then contiguous tower part is connected to together to form wind turbine tower.
[0004], before assembling, uses the long haul truck that wind turbine tower is transported to and build the place for known wind turbine.Transport with vehicle and to have from about 60 feet wind turbine tower parts to about 150 feet length, except its operability was not enough, road transport length was that 60 feet to 150 feet tower part also may be expensive.In addition, owing to be difficult to drive by the sharp turn, so must arrange special path to transport.And the pylon that loading and unloading are long from the truck also may be difficult.Therefore, must transport tower part by ship or helicopter sometimes, this dual mode all can increase cost.
[0005] consider afore-mentioned, if can build the pylon that the assembling easily of place, place is used for wind turbine, this will be favourable so.Yet the place, place may not implement to weld easily and other typically is used to make the mechanical coupling method of pylon building.Like this, just need a kind of alternate ways that wind turbine tower is partly connected together, can bear the wind condition that wind turbine typically stood and the wind turbine of temperature conditions to make.Especially, be used for adhesive that tower part is combined and come that to form wind turbine tower will be favourable building the place, place.In addition, using adhesive will more favourable in conjunction with the jar shape section of tower part to form tower part self at place, construction place.
Summary of the invention
[0006] in one aspect in, provide assembling to be used for the method for the pylon that uses together with wind turbine.This method comprises provides a plurality of tower sections.Each tower sections includes first interface and second contact surface.This method also comprises uses adhesive that first interface junction of first tower sections is incorporated on the second contact surface of second tower sections.
[0007] in one aspect of the method, provide and be used for the pylon that uses together with wind turbine.This pylon comprises a plurality of tower sections.Each tower sections includes first interface and second contact surface.By adhesive first interface junction of first tower sections is incorporated on the second contact surface of second tower sections.
[0008] in a further aspect, provide wind turbine assembly.This assembly comprises wind turbine and pylon.Wind turbine is connected on the pylon.This pylon comprises a plurality of tower sections.Each tower sections includes first interface and second contact surface.By adhesive first interface junction of first tower sections is incorporated on the second contact surface of second tower sections.
