Description
Technical field
The utility model belongs to wind turbine tower prestressed stretch-draw interconnection technique field, is a kind of wind power generating set concrete pylon prestressing with bond Shu Zhangla bindiny mechanism.
Background technique
The sternness of global energy anxiety and amblent air temperature problem, impels various countries' pay attention to day by day to the development and utilization of the renewable energy sourcess such as wind energy, solar energy, biological energy source.Wind-power electricity generation research starts to walk early, technology maturation, and what become renewable energy utilization reuses approach, and especially in recent years, installed capacity of wind-driven power obtains quick growth.China's wind energy contains abundant, wherein 2.53 hundred million kilowatts, land height 10 m place, and 50 m places can double; 7.5 hundred million kilowatts, coastal waters height 10 m place, 50 about 1,500,000,000 kilowatts, m places.By 2010, China's wind-power electricity generation reached 4,473 ten thousand kilowatts, had become most important renewable energy sources after water power.
The wind speed of hinterland is usually much lower than coastal area, in order to the wind energy turbine set in low wind speed area provides more generated energy in giving, blower fan supplier has two kinds mainly to select: they both can select to install the blower fan with larger wind wheel, also can not having transformed units' installation on higher wind tower.The selection of high tower only need increase the investment of appropriateness, just significantly can improve power stage.Such as, in non-coastal area, hub height often increases in 1m(limited field), yield increments is about 1%.Higher wind tower can also provide other advantages, as reduced Turbulent Flow Effects, reducing fatigue load, increase machine life, solve transport restrictions, reducing cost of material variation etc.
Because the limitation of steel tower material behavior and cost determine the inevitable of high concrete pylon, the cast-in-place concrete pylon construction time is longer, be difficult to meet wind field rapid construction requirement, precast concrete tower is arisen at the historic moment, how can ensure that precast concrete tower prestressing with bond is continuous, reduce losses of prestress, and simple to operate, the anchoring accurately reliable problem having become society and paid close attention to.
Model utility content
The purpose of this utility model is to provide a kind of wind power generating set concrete pylon prestressing with bond Shu Zhangla bindiny mechanism, can ensure Prestressed Continuous in concrete towers support body, reduce losses of prestress, and simple to operate, anchoring is accurately reliable.
The purpose of this utility model is achieved in that a kind of wind power generating set concrete pylon prestressing with bond Shu Zhangla bindiny mechanism, comprises the upper compression sleeve and lower anchoring anchor cylinder that are connected by attaching nut;
