Description
Technical field
The utility model is related to a kind of wind power plant tower buildings comprising：Tower, the tower include middle void tower portion and base
Portion；And one or more tension cables, at least one tension cable include：Pipeline, the pipeline have pipeline inner space
With the duct wall for surrounding the pipeline inner space；Two terminal bodies, each terminal bodies are respectively positioned on the respective end of the pipeline
And each terminal bodies all have one or more through-holes；And at least one tension element, at least one tension element
The pipeline inner space between described two terminal bodies is extended through, at least one tension element is conducted through respectively
At least one through-hole of terminal bodies and the side far from the pipeline inner space for being fixed on the terminal bodies.
Background technology
Cabin for generally including tower by the wind power plant of wind-power electricity generation, being set on tower and it is installed on cabin
The rotor with rotor blade.As the best part of wind power plant, therefore tower still most heavy part and occupies
The transport of wind power plant and the lion's share of installation cost.In addition to this, the structure of tower must endure as rotor and cabin
Dead load and the dynamic loading caused by the wind load on wind power plant.
With the capacity increase of wind turbine and for the common requirements of more regenerative resources, need to be used for wind
The higher tower-of power generating equipment especially is being only capable of finding the land of enough laminar flow wind speed in relatively high air layer
Upper position.
Traditionally, wind power plant is lattice tower (lattice tower) or the only tower made of steel pipe.Lattice tower has
There is limited rigidity, therefore is not suitable solution for higher wind power plant.In addition, establishing such grid
Time needed for structure is relatively long.Wind power plant with the only tower made of steel pipe is compared when building higher than the past
In mixed type tower or the tower made of concrete, particularly concrete half-shell or full shell (concrete half or full
Shell) more uneconomical.Importantly, the transport of such steel tube tower will produce problem, because the steel pipe for higher tower
Diameter is attributed to the clear span of most of bridges and too big for the transport on conventional street in some cases.In addition, steel
The vibration characteristics of the vibration characteristics of tower tower than mixed type tower or made of concrete is poor, leads to higher sound emission
(sound emission)。
In lower concrete portion and upper area of the mixed type wind power plant tower by post-tensioning (post-tensioned)
Steel portion constitute, and include engagement for post-tensioning lower concrete portion or cable external, be typically prefabricated.Lower section
Concrete section can be assembled by the concrete member (concrete half-shell or full shell) of pre-cast or can be with cast-in-place.It precoats
The transport of the concrete member of casting can almost carry out on all streets, though the section below of tower have it is relatively large straight
Diameter.
If the pipeline for cable of casting in the concrete of tower, is known as engaging cable (bonded cable).These connect
The shortcomings that zygonema cable, is that the larger tower wall intensity and cable for being attributed to penetrating for cable and needing loses by completely pre-
The ability of system.In addition, even if when using asynthetic cable, the stress elimination of this cable and dismounting are also troublesome and expensive
, but it is this dismantle-be attributed to tightened up regulation-after 25 years typical vital periods by more and more network operators need
It wants.
Therefore, External cable is typically used in mixed type wind power plant tower or the tower made of concrete now.This
The cable of type is directed to the concrete section of mixed type tower with or without deflector elements, in outside
Point or concrete towers and be fixed on the concrete parts of mixed type tower or some discrete locations of concrete towers.This cable can
Simply eliminated stress and nondestructive dismounting.
It is built for example, 1 262 614 A2 of EP disclose the concrete towers including this External cable being guided in tower
It builds, especially the wind power plant tower apparatus with concrete towers building.Cable includes some steel surrounded by pipeline sheath
Line, wherein including fat in intermediate space between intermediate space and steel wire itself between pipeline sheath and steel wire.EP 2
339 094 A1 disclose the method for building this tower building, wherein cable is maintained at tower top and column foot using cable terminations.
However, in those configurations, clamping plate in cable terminations is utilized to keep each steel wire so that each steel wire and its corresponding
Clamping plate occupies relatively large space in cable terminations.The space that each steel wire occupies in cable terminations is also by cable itself
The higher space consuming of each steel wire embodies.It is attributed to this, it is necessary to using with larger-diameter pipeline.This leads to cable
To the relatively large degree of eccentricity of tower wall, this is not preferred from the viewpoint of static state.In addition, in pipeline each steel wire the space
Cause the steel wire compactedness (filling grade) of pipeline will be relatively low, the steel wire compactedness of wherein pipeline refers in pipeline
The ratio of the total cross-sectional area of axial middle steel wire and the area of section of pipeline inner space.Steel wire compactedness is lower, needs
The amount of corrosion preventive compound is more, and the tower head and column foot and the diameter in the hole in cable terminations itself for cable terminations are bigger,
To obtain specific post-tensioning.The larger diameter in hole negatively affected the fatigue resistance of the especially cable terminations of system.
