Abstract

The utility model discloses a combined type foundation ring of a wind generating set. The combined type foundation ring comprises an upper end foundation ring and a lower end foundation ring, wherein the upper end foundation ring comprises an upper flange, a cylinder and a lower flange, the upper flange and the lower flange are fixedly arranged at the upper part and the lower part of the cylinder respectively, and the upper flange is connected with a fan tower barrel through a bolt; and the lower end foundation ring comprises a connecting flange, a conical barrel and a bottom flange which are connected into a whole from top to bottom sequentially, a large port of the conical barrel is located in the lower part, the connecting flange is connected and fixed with the lower flange of the upper foundation ring, and the lower end foundation ring and the lower part of the upper end foundation ring are buried into the concrete foundation. According to the combined type foundation ring, the lower end foundation ring provided with the conical barrel having the downward large port is added, so that the contact area with concrete is increased, the foundation ring is secondarily anchored, and the lower flange of the foundation ring is prevented from loosening and sliding, so that problems that a conventional foundation ring is prone to loosening and fatigue failure of foundation concrete is caused easily are effectively solved.

Description

A kind of wind power generating set combined type discharge ring
Technical field
The utility model relates to wind-driven generator field, relates in particular to a kind of wind power generating set combined type discharge ring.
Technical background
Wind power generating set discharge ring is the device that wind-power generating unit tower and concrete foundation are linked together, at present, discharge ring is generally cylinder type, it comprises upper flange, cylinder, lower flange, upper flange is connected with blower fan tower barrel by bolt, and cylinder bottom and lower flange are embedded in concrete foundation.Because draught fan impeller can produce all directions under wind action, the swing of different amplitudes, this swing meeting swings together with discharge ring, wherein maximum along prevailing wind direction amplitude of fluctuation, under this kind long-term reciprocal and irregular swing, contacting between this discharge ring and concrete foundation is progressively destroyed, cause producing between discharge ring and concrete foundation relative displacement even loosening, so discharge ring barrel and discharge ring lower flange can apply periodically compressive stress to concrete foundation, make the concrete generation office being in contact with it crush bad and fatigue failure, thereby affect safety and the application life of wind power generating set.
Utility model content
The purpose of this utility model is to overcome above defect, provides a kind of discharge ring to be difficult for loosening, reduces a kind of wind power generating set combined type discharge ring of base concrete fatigue failure.
The technical solution of the utility model is: a kind of wind power generating set combined type discharge ring, it comprises upper end discharge ring and lower end discharge ring, upper end discharge ring comprises upper flange, cylinder, lower flange, upper flange and lower flange are fixedly installed on respectively the upper and lower of cylinder, upper flange is connected with blower fan tower barrel by bolt, described lower end discharge ring comprises adpting flange, conically shaped, end flange, adpting flange, conically shaped, end flange is in turn connected into an integral body from top to bottom, large mouthful of described conically shaped in bottom, the lower flange of adpting flange and upper end discharge ring is connected and fixed, the bottom of lower end discharge ring and upper end discharge ring is embedded in concrete foundation.
In order to strengthen the adhesion strength between upper end discharge ring and concrete, on the cylinder of described Transducers Embedded in Concrete part along circumference setting at least 1 circle, every number of turns amount be no less than 2 wear muscle hole.
The described muscle hole of wearing has at least a circle to be arranged on concrete upper strata.
In order to strengthen lower end discharge ring and mixed earth anchoring interlocking and to guarantee that it does not hinder reinforcing bar through lower end discharge ring, is provided with at conically shaped barrel the strip through-hole that quantity is no less than 2.
Described strip through-hole is the longitudinal bar hole arranging along conically shaped barrel circumferencial direction.
Effect of the present utility model is: owing to having increased lower end discharge ring, lower end discharge ring is provided with the conically shaped of large mouth down, increase the contact area with mixed earth, effectively reduce local stress, and discharge ring is carried out to secondary anchoring, prevent that discharge ring lower flange from producing loosening slippage, thereby effectively solved the problem that traditional discharge ring easily becomes flexible, easily causes base concrete fatigue failure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that the utility model embodiment puts into the generalized section after concrete.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing, a kind of wind power generating set combined type discharge ring, it comprises upper end discharge ring 1 and lower end discharge ring 6, upper end discharge ring 1 comprises upper flange 2, cylinder 3, lower flange 4, upper flange 2 and lower flange 4 are weldingly fixed on respectively the upper and lower of cylinder 3, cylinder 3 tops are provided with and wear muscle hole 5 along even circumferential, the quantity of wearing muscle hole 5 is 60, wear muscle hole 5 on the upper strata of concrete foundation 11, upper flange 2 is connected with blower fan tower barrel by bolt, described lower end discharge ring 6 comprises adpting flange 7, conically shaped 8, end flange 9, adpting flange 7, conically shaped 8, end flange 9 is welded into an integral body from top to bottom successively, large mouthful of described conically shaped 8 in bottom, conically shaped 8 barrels are longitudinally evenly provided with bar hole 10, the quantity of bar hole 10 is 60, adpting flange 7 with the lower flange 4 of upper end discharge ring 1 by bolt or together with being welded and fixed, lower end discharge ring 6 is embedded in concrete foundation 11 with the bottom of upper end discharge ring 1.
Be more than a kind of embodiment of the present utility model, a preferred demonstration example.The scope that the utility model application is asked for protection has more than and is limited to described embodiment.All and technical scheme the present embodiment equivalence all belongs to protection domain of the present utility model.
