Description

Technical Field

[0001] The invention relates to a wind power tower foundation ring, in particular to a convenient and highly stable wind power tower foundation ring. Background Art

[0002] The wind turbine tower is the tower pole of wind power generation and the basic component of the wind turbine generator set. It mainly plays the role of supporting and raising the wind turbine 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 the corresponding concrete foundation, and the upper end of the tower foundation ring is connected to the bottom of the generator tower through a locking flange. In order to ensure that the tower foundation ring has sufficient stability, a corresponding bottom flange is generally provided at the bottom of the tower foundation ring, and the first fixation of the tower foundation ring is achieved by connecting the bottom flange with the anchor rod pre-buried under the concrete. Single anchor rod fixation cannot meet the required fixing requirements, so the existing tower foundation ring will have radial holes in its upper part to allow steel bars to pass through it, and then be buried in the concrete foundation for the second fixation. However, since the opening of the upper part of the tower foundation ring will reduce the connection strength, stress concentration will occur at the opening, thereby accelerating structural fatigue, resulting in a decrease in the stability of the tower foundation ring, resulting in safety hazards in the production and use of wind turbine towers. Therefore, the research purpose of the present invention is to design a portable high-stability wind turbine tower foundation ring that can effectively improve the stability of the tower foundation ring, does not require drilling holes, does not damage the inherent structure of the foundation ring, and has a simple structure and convenient transportation and assembly construction process. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a convenient high-stability wind turbine tower foundation ring, which can effectively solve the problems existing in the above-mentioned prior art.

[0004] The technical solution of the present invention is:

[0005] A convenient high-stability wind power tower foundation ring comprises a foundation cylinder and a stable pulling mechanism, wherein a corresponding locking flange is welded on the upper end of the foundation cylinder, and a corresponding bottom flange is welded on the lower part of the foundation cylinder, and a plurality of corresponding flange holes are arranged on the locking flange and the bottom flange, and a plurality of corresponding longitudinal positioning blocks are welded at equal angles on the outer wall of the foundation cylinder, and a corresponding supporting plate is arranged at the bottom of the longitudinal positioning block, and the longitudinal positioning block and the supporting plate are an integrated structure, and T-slots connected to the supporting plate are arranged on the outer sides of the longitudinal positioning blocks, and corresponding right-angled triangle clamping plates are detachably installed in the T-slots, and the right-angled triangle clamping plates are detachably installed in the T-slots. One side of the right-angled long side of the plate is matched with the T-slot to form a T-shape, and a positioning device on one side of the right-angled long side of the right-angled triangle clamping plate is located in the corresponding T-slot; the stable pulling mechanism includes an annular connecting plate, and the inner side of the annular connecting plate is inclined with a plurality of positioning grooves that match the right-angled triangle clamping plate. The annular connecting plate cooperates with the corresponding right-angled triangle clamping plate through the positioning grooves provided thereon. The positioning device is on the outer side of the base cylinder, and the outer sides of the annular connecting plate are respectively fixedly connected downwardly with a plurality of corresponding connecting rods, and the bottom peripheries of the connecting rods are fixedly connected to the corresponding annular locking plates, and the annular locking plates are provided with a plurality of corresponding locking holes at equal angles.

[0006] The flange holes on the bottom flange are respectively fixed to the first anchor rods embedded under the concrete foundation through locking bolts.

[0007] The locking holes provided on the annular locking plate are respectively fixed to the second anchor rods pre-buried under the concrete foundation through corresponding locking bolts.

[0008] Advantages of the present invention:

[0009] The outer wall of the basic cylinder of the present invention is welded with a plurality of corresponding longitudinal positioning blocks at equal angles, and the bottom of the longitudinal positioning blocks is provided with corresponding support plates, and the outer sides of the longitudinal positioning blocks are respectively provided with T-slots connected to the support plates, and the corresponding right-angled triangle clamps are respectively detachably installed in the T-slots, and the positioning device on one side of the right-angled long side of the right-angled triangle clamp is in the corresponding T-slot, and the stable pulling mechanism includes an annular connecting plate, and the annular connecting plate cooperates with the corresponding right-angled triangle clamp through the positioning groove provided therein. The positioning device is on the outer side of the basic cylinder, and the outer side of the annular connecting plate is respectively tilted downward and fixedly connected with a plurality of corresponding connecting rods, and the bottom peripheries of the connecting rods are all fixedly connected to the corresponding annular locking plates. In this way, under the action of the stable pulling mechanism, a second fixing can be added on the basis of a single fixing of the bottom flange without drilling holes in the basic cylinder.

[0010] The annular connecting plate and the annular locking plate of the stable pulling mechanism of the present invention are connected by a plurality of connecting rods evenly distributed to form an integral body. On the one hand, it is convenient for transportation and installation. On the other hand, under the action of the second anchor rod, it effectively forms an integral, uniform and comprehensive effective pull on the outside of the basic cylinder, and at the same time increases the contact with the concrete foundation, greatly improving the stability of the basic cylinder.

[0011] During the transportation process of the present invention, the basic cylinder, the right-angled triangular clamping plate and the stable pulling mechanism can be transported separately. When arriving at the installation site, they can be assembled immediately. It realizes the advantages of effectively improving the stability of the tower barrel foundation ring, without the need for drilling holes, without damaging the inherent structure of the foundation ring, and having a simple structure and a convenient transportation and assembly construction process.
