An arc plate 5 is provided on the inner side of the limit frame 3 and a first buffer is provided between the two. The arc plate 5 is in a vertical direction and overlaps with the outer surface of the wind turbine tower. The first buffer can be used to initially buffer the vibration of the wind turbine tower. A second buffer is provided between the grounding rod 2 and the reinforcement ring 1. The second buffer can transmit the vibration force of the reinforcement ring 1 to the grounding rod 2, and then transmit it to the ground by the grounding rod 2;

[0024] In the initial state, the two reinforcement rings 1 are in a separated state, and the arc plate 5 is away from the axis of the reinforcement ring 1. When the wind turbine tower is installed, the two reinforcement rings 1 are kept in a vertical direction and overlapped, and the bottom of the reinforcement ring 1 overlaps with the ground, so that multiple grounding rods 2 overlap with the ground. The two reinforcement rings 1 are surrounded by an annular structure and are located on the outer periphery of the wind turbine tower. The two reinforcement rings 1 are connected by multiple connecting parts, and multiple screw rods 4 are rotated forward in turn, and multiple limit frames 3 slide in the horizontal direction close to the wind turbine tower until The screw rod 4 cannot continue to rotate forward, and the multiple arc plates 5 are all in contact with the outer facade of the wind turbine tower. During the long-term absorption of the vibration of the wind turbine tower, the vibration of the wind turbine tower is initially buffered by the multiple first buffers. The reinforcement ring 1 is subjected to the vibration force generated by the wind turbine tower, and the vibration force of the reinforcement ring 1 is transmitted to the grounding rod 2 by the multiple second buffers, and then transmitted to the ground by the grounding rod 2, thereby reducing the vibration force and vibration frequency of the wind turbine tower to avoid loosening of the fixed structure, thereby improving the stability of use;

[0025] To sum up, when the present application is in use, multiple first buffer parts are used together to perform preliminary buffering on the vibration of the wind turbine tower. The reinforcement ring 1 is subjected to the vibration force generated by the wind turbine tower. The vibration force of the reinforcement ring 1 is transmitted to the grounding rod 2 through multiple second buffer parts, and then transmitted to the ground by the grounding rod 2, thereby reducing the vibration force and vibration frequency of the wind turbine tower to avoid loosening of the fixed structure, thereby improving the stability of use and being more practical.

[0027] Referring to the above, in the initial state, the connecting block 6 is separated from the hinge seat 8, and the connecting nut 10 is separated from the connecting screw 9. When the two reinforcement rings 1 are surrounded to form an annular structure, the connecting block 6 and the hinge seat 8 are in contact and overlapped, so that the connecting screw 9 rotates around the hinge point to be located in the notch 7, and then the connecting nut 10 is tightened onto the connecting screw 9 until the connecting nut 10 is in contact and overlapped with the connecting block 6. At this time, the two reinforcement rings 1 cannot be separated, and the connection of the two reinforcement rings 1 can be achieved. Conversely, the connecting nut 10 is loosened until it is disengaged from the connecting screw 9, and the two reinforcement rings 1 can be separated to achieve the contact connection of the two reinforcement rings 1.

The overall structural stability can be further improved by using multiple anchor rods 18.

The free ends of the first piston rod and the second piston rod are respectively hinged to the grounding rod 2 and the reinforcement ring 1, and the viscous medium layer of the viscous fluid damper 19 is a silicone oil layer. The silicone oil layer has good stability and aging resistance, and can improve the buffering effect to a certain extent;

[0035] Referring to the above, when the reinforcement ring 1 is subjected to the vibration force generated by the wind turbine tower, the first piston rod and the second piston rod of the viscous fluid damper 19 will produce relative movement and repeatedly squeeze the viscous medium layer, thereby buffering the vibration force.
