[0002] Tall buildings such as wind turbine towers will vibrate frequently due to external climate influences such as strong winds and vibrations caused by the operation of facilities installed thereon, which may cause safety hazards to tall buildings such as wind turbine towers. To solve this problem, there are a series of damping and vibration reduction devices in the prior art, such as the existing patents with publication numbers CN218543040U and CN211396057U, which mostly use mechanical elastic pulling damping. However, the mechanical device has fatigue limitations and there are still certain safety hazards. Summary of the invention

[0003] The purpose of the present invention is to solve the problems existing in the prior art and to provide a magnetic anti-wind damping and vibration reduction device, which achieves the effect of anti-wind damping and vibration reduction through the combined action of gravity and magnetic repulsion, and has the advantages of easy installation, safety and stability, simple maintenance, small space occupation and low cost.

[0004] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0005] A magnetic anti-wind damping and vibration reduction device comprises a non-magnetic mounting ring and a non-magnetic base arranged at the bottom of the non-magnetic mounting ring, the top surface of the non-magnetic base is a spherical surface with a low middle and high edges, a non-magnetic counterweight is arranged on the inner side of the non-magnetic mounting ring, a plurality of universal wheels are arranged at the bottom of the non-magnetic counterweight, and the non-magnetic counterweight moves on the top surface of the non-magnetic base through the universal wheels, a plurality of first magnets are evenly arranged on the outer wall of the non-magnetic base along the circumference of the non-magnetic base, a plurality of second magnets are evenly arranged on the inner wall of the non-magnetic mounting ring along the circumference of the non-magnetic mounting ring, and the magnetic poles of the second magnets are the same as those of the ends close to the first magnets.

[0006] Preferably, the second magnet is arranged obliquely on the inner wall of the non-magnetic mounting ring, and one end of the second magnet away from the inner wall of the non-magnetic mounting ring is inclined downward.

[0007] Preferably, a wedge-shaped mounting frame for mounting the second magnet is provided on the inner wall of the non-magnetic mounting ring.

[0008] Preferably, the wedge-shaped mounting frame is a non-magnetic frame.

[0009] Preferably, the cross section of the non-magnetic counterweight block is a regular polyhedron, and a first magnet is arranged on each outer side of the non-magnetic counterweight block.

[0010] Preferably, the non-magnetic base is located inside the non-magnetic mounting ring, and the top end of the non-magnetic base abuts against the inner wall of the non-magnetic mounting ring.

[0011] Preferably, eight first magnets are arranged on the outer wall of the non-magnetic counterweight block, and sixteen second magnets are arranged on the inner wall of the non-magnetic mounting ring.

[0012] Preferably, the first magnet and the second magnet are both electromagnets or permanent magnets.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The non-magnetic mounting ring of the present invention is fixed on the inner wall of a tall building such as a wind turbine tower. When not affected by external force, the non-magnetic counterweight is located in the middle of the top surface of the non-magnetic base. When the tall building such as the wind turbine tower shakes, the present invention causes the following displacement. Due to inertia, the non-magnetic counterweight moves in the direction opposite to the displacement of the tall building. As a result, the non-magnetic counterweight is subjected to the force in the displacement direction due to its own gravity and the repulsion of like poles. The non-magnetic counterweight moves in the displacement direction. The combined effect of gravity and magnetic repulsion achieves the effect of wind damping and shock absorption. The invention has the advantages of easy installation, safety and stability, simple maintenance, small space occupation and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example: As shown in the attached Figure 1-2As shown, the present invention is a magnetic wind-resistant damping and vibration reduction device, comprising a non-magnetic mounting ring 1 and a non-magnetic base 2 arranged at the bottom of the non-magnetic mounting ring 1, the top surface of the non-magnetic base 2 is a spherical surface with a low middle and a high edge, the non-magnetic mounting ring 1 and the non-magnetic base 2 are both made of non-magnetic materials, such as plastic, ceramic, etc., the non-magnetic mounting ring 1 is in a circular ring shape, and the non-magnetic mounting ring 1 is fixed on the inner wall of the wind turbine tower (or building), an integrated structure can be adopted between the non-magnetic base 2 and the non-magnetic mounting ring 1, and the non-magnetic base 2 and the non-magnetic mounting ring 1 can also be connected as a whole by fasteners made of non-magnetic materials.

[0020] A non-magnetic counterweight 3 is provided on the inner side of the non-magnetic mounting ring 1, a plurality of universal wheels 4 are installed at the bottom of the non-magnetic counterweight 3, the non-magnetic counterweight 3 is placed on the top of the non-magnetic base 2, and the non-magnetic counterweight 3 moves on the top surface of the non-magnetic base 2 through the universal wheels 4, a plurality of first magnets 5 are evenly provided on the outer wall of the non-magnetic base 2 along the circumference of the non-magnetic base 2, a plurality of second magnets 6 are evenly provided on the inner wall of the non-magnetic mounting ring 1 along the circumference of the non-magnetic mounting ring 1, and the magnetic poles of the second magnets 6 and the end close to the first magnet 5 are the same.

[0021] Preferably, since the non-magnetic counterweight 3 is located on a spherical surface with a low middle and high edge, the height of the first magnet 5 on the non-magnetic counterweight 3 is lower than the height of the second magnet 6. To this end, the second magnet 6 is arranged obliquely on the inner wall of the non-magnetic mounting ring 1, and the end of the second magnet 6 away from the inner wall of the non-magnetic mounting ring 1 is tilted downward so that the second magnet 6 faces the first magnet 5 to ensure the repulsive force between the first magnet 5 and the second magnet 6.

[0022] Preferably, in order to facilitate the installation of the second magnet, a wedge-shaped mounting frame 7 for mounting the second magnet 6 is provided on the inner wall of the non-magnetic mounting ring 1 .

[0023] Preferably, the wedge-shaped mounting frame 7 is a non-magnetic frame.

[0024] The non-magnetic counterweight block can be a cylinder, and the first magnet 5 is embedded on the outer wall of the cylinder. Preferably, the cross-section of the non-magnetic counterweight block 3 is a regular polyhedron, and a first magnet 5 is embedded on each outer side of the non-magnetic counterweight block 3.

[0025] Preferably, the non-magnetic base 2 is located inside the non-magnetic mounting ring 1 , and the top end of the non-magnetic base 2 abuts against the inner wall of the non-magnetic mounting ring 1 .

[0027] Preferably, the first magnet 5 and the second magnet 6 are both electromagnets or permanent magnets.

[0028] When in use, first, the present invention is fixed on the inner wall of the wind turbine tower (or building); when wind comes from any direction, the wind turbine tower (or building) shakes, causing the present invention to follow the displacement; due to inertia, the non-magnetic counterweight 3 will move in the opposite direction of the displacement, so that the non-magnetic counterweight 3 will be subjected to the force in the displacement direction due to gravity and the repulsion of like poles, and the non-magnetic counterweight 3 will move in the displacement direction; thus, the present invention is generally embodied as a force applied to the wind turbine tower (or building) in the opposite direction of the displacement; when the wind turbine tower (or building) changes its displacement direction, the present invention is always embodied as a force applied to the wind turbine tower (or building) in the opposite direction of the displacement; after multiple multi-directional actions, the swing amplitude is gradually suppressed, thereby playing a damping role.
