Abstract
The invention relates to a foundation of a wind-driven generator unit. The foundation comprises a foundation ring, a foundation bearing platform and a foundation stake, wherein the foundation stake is arranged at the middle lower part of the foundation bearing platform; the lower part of the foundation bearing platform is a reinforced concrete cylinder or a regular multi-lateral body, the upper part of the foundation bearing platform is a reinforced concrete tapered round platform, and the steel foundation ring is arranged in the middle of the foundation bearing platform; the size of the foundation ring is matched with the diameter of a tower mounted at the upper part of the foundation ring; the foundation stake is a reinforced concrete cylinder; the foundation bearing platform and the foundation stake are arranged in a foundation pit; and the upper surface of the foundation ring is higher than the foundation horizontal plane. The foundation well combines the advantages of a traditional extended foundation and a pile foundation bearing platform foundation, gives full play to the overturning-resistant effects of respective structural styles of both the foundation bearing platform and the stake, and performs a combined resisting function of the two in a unified manner.
Description
Technical field
The present invention relates to the wind-driven generator field, relate in particular to a kind of basis of wind-driven generator.
Technical background
In the world wide, in order to utilize to greatest extent limited wind energy resources, land resources, wind-power market requires wind power generating set more and more urgent to trend high-power, the linear leaf development, along with wind power generating set power is increasing, it is increasing that wind-driven generator is delivered to basic load, it is increasing that so traditional gravity enlarges basis (seeing accompanying drawing 1) scale, not only occupy cultivated land in a large number, and the use of concrete in mass also causes very large pressure to environment, runs counter to the development aim of wind-power electricity generation green energy resource.
Summary of the invention
The object of the invention is to overcome above defective, provide a kind of floor space little, basic own vol is little, concrete, reinforcing bar materials are few, the wind power generating set basis that resistance to capsizing is high.
Technical scheme of the present invention is, a kind of wind power generating set basis, comprise: discharge ring, foundation platform and basic pile, foundation platform and basic pile place in the foundation ditch, the basis pile is located at the middle and lower part of foundation platform, foundation platform lower rebar concrete is cylinder or positive gengon, foundation platform upper reinforcement concrete is the taper round platform, discharge ring is located at the foundation platform middle part, the size of discharge ring and tower cylinder diameter are complementary, the tower cylinder is installed in discharge ring top, and the upper surface of discharge ring is higher than the base water plane.
The cylindrical of described basic pile is provided with cylindrical sleeve.
Described cylindrical sleeve is the ripple steel cylinder.
Filling concrete between described cylindrical sleeve and the foundation ditch.
Described foundation platform and basic pile and ground contact position all are equipped with concrete cushion.
The present invention well combines the advantage on traditional spread footing and pile foundation support table basis, gives full play to the two the separately form of structure antidumping of foundation platform and pile, and the two good unified formation is closed resistant function.
Description of drawings
Fig. 1 is traditional spread foundation;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the top view of Fig. 2;
Fig. 4 is that the present invention resists the overturning moment schematic diagram.
The specific embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
A kind of wind power generating set basis, it comprises: steel discharge ring 1, foundation platform 2 and basic pile 3, basis pile 3 is located at the middle and lower part of foundation platform 2, the bottom of described foundation platform 2 is Reinforced Concrete Circular Cylinder body or positive gengon, the top of foundation platform 2 is the taper round platform of steel concrete, steel discharge ring 1 is located at foundation platform 2 middle parts, the size of steel discharge ring 1 and tower cylinder diameter are complementary, the tower cylinder is installed in steel discharge ring 1 top, described basic pile 3 is a Reinforced Concrete Circular Cylinder body, foundation platform 2 and basic pile 3 place in the foundation ditch, and the upper surface of steel discharge ring 1 is higher than the base water plane.In order to reduce the demoulding, the cylindrical of described basic pile 3 is provided with cylindrical ripple steel cylinder 4.Filling concrete 5 between cylindrical ripple steel cylinder 4 and foundation ditch.Before building foundation platform 2 and basic pile 3 concrete, must lay first concrete cushion 6 and basic pile bed course 7 on the foundation platform 2.
This basis is when bearing the limit overturning moment that transmits on blower fan top, basis one side pressurized, opposite side is tension then, the basis interacts with ground ground 8 by foundation platform 2 and basic pile 3 and produces the limit overturning moment that three bursts of opposing moments of flexure transmit to offset blower fan top, thereby guarantees the operation of blower fan stability and safety.
Below only be a kind of example of the present invention, all base forms that meets the principle of the invention are all in protection scope of the present invention.
