AI Technical Summary
In existing technologies, the connection stability between the wind turbine tower base and the tower body mainly relies on bolt fixing. As the service time increases, the stability of the bolts decreases, leading to a decline in the stability of the tower base and the tower body.
The combination of bolts and compression rings, along with the sliding connection between the compression ring and the pressure-bearing block, distributes the pressure of the bolts. The fixed block and the pressure-bearing block jointly bear the pressure between the tower base and the tower cylinder, thereby enhancing the connection stability.
It improves the service life of bolts and the connection stability between the tower base and the ground, reduces the stress on bolts, simplifies operation, and enhances the overall stability of wind power tower bases.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbine tower foundation technology, specifically a wind turbine tower foundation stabilization device. Background Technology
[0002] The wind turbine tower base is an important component of the wind turbine generator set. It is used to install and support the wind turbine generator set and balance the various loads generated by the wind turbine generator set during operation to ensure the safe and stable operation of the unit. The tower base is located at the bottom of the tower.
[0003] Existing technology uses multiple bolts to fix the tower base to the ground. Relying solely on bolts for fixation puts the bolts under tremendous pressure, and as the service life increases, the stability of the bolts gradually decreases, leading to a reduction in the stability of the tower base and tower cylinder. Utility Model Content
[0004] The purpose of this invention is to provide a wind turbine tower foundation stabilization device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower base stabilization device, comprising a foundation and a tower base, a tower cylinder fixedly connected to the top of the tower base, a plurality of bolts arranged in an array threaded connection on the tower base, a plurality of mounting grooves arranged in an array on the tower base, a compression ring fixedly connected to each bolt at a position corresponding to the mounting groove, a pressure-bearing block slidably connected inside each mounting groove, a leverage groove opened at the top of each pressure-bearing block, a threaded groove opened at the top of the foundation at a position corresponding to the bolt, a plurality of fixing blocks arranged in an array fixedly connected to the foundation, each fixing block having a fixing groove.
[0006] Preferably, the bottom end of each bolt is located inside the mounting groove.
[0007] Preferably, one of the outer walls of the pressure-bearing block is inclined.
[0008] Preferably, the bottom corners of the extrusion ring are all arc-shaped, and the arc-shaped bottom corners of the extrusion ring abut against the outer wall of the corresponding pressure block which is inclined.
[0009] Preferably, the compression rings are all located inside the mounting groove, and the tower base is located at the top of the foundation.
[0010] Compared with the prior art, the beneficial effects of this utility model are: by using bolts and compression rings together, the pressure-bearing blocks and the fixing blocks can be connected. When the bolts fix the tower base to the foundation, each pressure-bearing block will also be connected to the interior of the fixing block. At this time, the fixing block and the pressure-bearing block will share the pressure of the tower base and the tower cylinder with the bolts, which can reduce the pressure on the bolts, thereby improving the service life of the bolts. It can also greatly improve the connection stability between the tower base and the foundation. It is easy to operate, highly practical, and worth promoting. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4 This utility model provides a technical solution: a wind turbine tower foundation stabilization device, including a foundation 1 and a tower base 2. A tower cylinder 3 is fixedly connected to the top of the tower base 2. A plurality of bolts 4 arranged in an array are threadedly connected to the tower base 2. A plurality of mounting grooves 5 arranged in an array are opened on the tower base 2. A compression ring 6 is fixedly connected to each bolt 4 at the position corresponding to the mounting groove 5. A pressure block 7 is slidably connected inside each mounting groove 5. A force-bearing groove 8 is opened at the top of each pressure block 7. A threaded groove 9 is opened at the top of the foundation 1 at the position corresponding to the bolt 4. A plurality of fixing blocks 10 arranged in an array are fixedly connected to the foundation 1. A fixing groove 11 is opened on each fixing block 10.
[0018] The bottom ends of bolts 4 are all located inside the mounting groove 5. One of the outer walls of the pressure block 7 is inclined to facilitate the compression ring 6 to compress the pressure block 7. The bottom corners of the compression ring 6 are all arc-shaped. The arc-shaped bottom corners of the compression ring 6 abut against the corresponding inclined outer wall of the pressure block 7. When the arc-shaped corners of the compression ring 6 compress the inclined outer wall of the pressure block 7, the pressure block 7 will move. The compression rings 6 are all located inside the mounting groove 5. The tower base 2 is located at the top of the foundation 1.
[0019] Specifically, when using this utility model, the bolt 4 can be rotated using an external tool. The bolt 4 will move downwards as it rotates, and the rotating and moving bolt 4 will cause the compression ring 6 to rotate and move together. During the downward movement, the arc-shaped corner of the compression ring 6 will press against the inclined outer wall of the pressure block 7. At this time, the pressure block 7 will slide inside the mounting groove 5 and slide towards the corresponding fixing block 10. Then, the sliding pressure block 7 will connect to the fixing groove 11 on the fixing block 10. At this time, the bottom end of the rotating and downward moving bolt 4 will also connect to the inside of the threaded groove 9 on the foundation 1. At this time, the foundation 1 and the tower base 2 are fixedly connected by the bolt 4, and the pressure block 7 is also connected to the fixing groove 11 on the fixing block 10. At this time, the fixing block 10 and the pressure block 7 can jointly bear the pressure from the tower base 2 and the tower cylinder 3 for the bolt 4. The operation of the other bolts 4 is the same, and the operation is extremely convenient. When the bolt 4 moves upwards, the pressure block 7 can be reset to its original position by using the leverage groove 8.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
