Background
The wind power tower is a tower pole of wind power generation, is a basic component of a wind power generator set, and mainly plays a role in supporting and heightening the wind power generator set. The tower foundation ring under the tower is subjected to huge vertical pressure and lateral bending moment. The existing tower foundation ring is generally buried in a corresponding concrete foundation, and the upper end of the tower foundation ring is connected with the bottom of the generator tower through a locking flange. In order to ensure that the tower foundation ring has enough stability, the bottom of the tower foundation ring is generally provided with a corresponding bottom flange, and the first fixing of the tower foundation ring is realized through the connection of the bottom flange and an anchor rod pre-buried under the concrete. The single anchor rod cannot be fixed to the required fixing requirement, so that the existing tower foundation ring is radially perforated at the upper part of the tower foundation ring so that the reinforcing steel bars can pass through the tower foundation ring and then are buried in the concrete foundation for second fixing. But because the connection strength can be reduced by perforating the upper part of the tower foundation ring, stress concentration phenomenon can be generated at the perforating position, so that structural fatigue is accelerated, the stability of the tower foundation ring is reduced, and potential safety hazards exist in the production and use of the wind power tower. Therefore, the design of the foundation ring of the wind power tower can effectively improve the stability of the foundation ring of the tower, does not need to be perforated, cannot damage the inherent structure of the foundation ring, has simple structure, and is convenient and fast in transportation and assembly construction processes, and the foundation ring of the wind power tower is the research purpose of the invention.

The flange holes on the bottom flange are fixedly connected to first anchor rods pre-buried below the concrete foundation through locking bolts respectively.
The locking holes arranged on the annular locking plate are respectively fixed on a second anchor rod pre-buried below the concrete foundation through corresponding locking bolts.
The invention has the advantages that:
The invention discloses a foundation barrel, which is characterized in that a plurality of corresponding longitudinal positioning blocks are welded on the outer side wall of the foundation barrel according to equal angles, corresponding supporting plates are arranged at the bottoms of the longitudinal positioning blocks, T-shaped grooves communicated with the supporting plates are respectively arranged on the outer sides of the longitudinal positioning blocks, corresponding right-angle triangle clamping plates are respectively detachably arranged in the T-shaped grooves, a right-angle long side positioning device of each right-angle triangle clamping plate is arranged in the corresponding T-shaped groove, a stable pulling mechanism comprises an annular connecting plate, the annular connecting plate is matched with the corresponding right-angle triangle clamping plates through positioning grooves arranged on the annular connecting plate and is positioned on the outer side of the foundation barrel, a plurality of corresponding connecting rods are respectively and fixedly connected on the outer sides of the annular connecting plates in a downward inclined mode, and the peripheries of the bottoms of the connecting rods are fixedly connected to corresponding annular locking plates. Therefore, under the action of the stable pulling mechanism, the second fixing can be additionally arranged on the basis of single fixing of the bottom flange without punching holes on the basic cylinder body.
The annular connecting plate and the annular locking plate of the stable pulling mechanism are connected through a plurality of uniformly distributed connecting rods to form a whole. Firstly, be convenient for transport and installation, secondly come under the effect of second stock, effectively form whole, even, comprehensive effective tractive in the outside of basis barrel, increased simultaneously with the contact of concrete foundation, promoted the stability of basis barrel to a great extent.
In the transportation process, the basic cylinder, the right triangle clamping plate and the stable traction mechanism can be transported separately, when the mounting site is reached, the assembly is carried out on the horse. The stability of tower section of thick bamboo foundation ring is effectively improved in the realization, need not the trompil, can not produce the destruction to the inherent structure of foundation ring, and the structure is simple and easy, and transportation and the convenient advantage of assembling the work progress.
