Description
Technical field
The utility model relates to the capital construction technical field, specifically is a kind of pylon structure, for example the pylon structure of wind-driven generator.
Background technique
Along with fast development of social economy, people grow with each passing day to demands for energy, and the environmental pollution that brings thus also increases the weight of day by day.Wind energy is a kind of renewable energy sources of cleaning, thereby wind-driven generator more and more receives the concern and the application of countries in the world.
The wind-power generating unit tower structure is the tall and slender structure pattern as visual plant in the wind-powered electricity generation industry, not only holds the action of gravity of wind power generating set, more bears the lateral forces that wind produces.In order to ensure the blower fan safe and stable operation, it is particularly important that the design of pylon structure becomes.
Because beautiful shape, it is little to take up room, and support height is high, and the free stand tower structure has obtained extensive use in Large-scale Wind Turbines.Traditional free stand tower generally adopts the steel tower tube of cylindricality or taper, is formed by connecting through flange a plurality of segmentations.But along with the wind power generating set development trend of large-scale, the height of tower tube and diameter are all increasing, and following problem has appearred in the free stand tower structure in application:
1, major diameter tower tube production, transportation, installation cost height.The manufacturing in the workshop of tower tube needs large-scale manufacturing equipment, and each segmentation needs large diameter flange connection, cost of production increase; Receive the restriction of the load-carrying of road or the aspects such as permission height under radius of turn, bridge and the tunnel, transport difficulty increases; Major diameter tower tube weight is big, needs the large-tonnage hoist during installation, and installation cost increases.Because receive the restriction of existing manufacturing equipment, road and crane output, the manufacturing of Large Towers tube, transportation and installation exist many problems and need solution badly.
2, major diameter tower tube needs large foundation to support.The tower tube not only bears the gravity of unit, also bears the lateral force that wind produces.Because the tensile stress up and down that the lateral forces of wind produces on the tower tube is greater than the gravity of unit, so the intensity of tower tube must not improve several times virtually.Because the height and the diameter of tower tube are bigger than very, can reach tens times, so the accretion that has caused tens times of lateral forces in order to resist this effect, suitably increases the thickness and the diameter of tower tube in the tower tube.But side direction wind has still formed huge overturning moment at the tower tube bottom, therefore, needs large-scale firm this effect of reinforced concrete foundation opposing.Yet traditional isolated footing anti-pressure ability is had a surplus, and bending resistance is not enough, in order to satisfy the big requirement of wind power generating set basis overturning moment, needs to increase the base plane size, and the usefulness of fondational structure is tending towards reducing, and has caused the bigger waste of design resource.And the construction on basis belongs to the Reinforced Concrete construction, long construction period, big, the poor stability of constructional difficulties, and construction quality is difficult to guarantee.
In sum, the production of major diameter tower barrel structure, transportation, installation cost height, and need large-scale reinforced concrete foundation to support, and also traditional wind power generating set Base Design is not enough with the construction existence.Therefore, in order to advance the development of wind-powered electricity generation industry, existing pylon structure is optimized or researches and develops new pylon structure pattern becomes an inexorable trend.
