Description
Technical field
The utility model belongs to wind turbine tower technical field, is a kind of steel concrete combination pylon prestressed concrete steel transformation segment.
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 steel reinforced concrete closes pylon and arises at the historic moment, pylon is closed for precast concrete steel reinforced concrete, except considering inside and outside precast concrete segment body except pre-stressed anchor rods anchorage problem, that also should consider concrete towers frame and steel tower is connected and fixed problem, ensure that mixing pylon steel section is effectively combined with concrete segment, guarantee the even transmission of fan loads in pylon, ensure the prestress application of concrete segment pylon, reduce losses of prestress, and construction is simple, easy to maintenance.
