[0028] Example 1
[0029] A multi-layer tuned liquid damper for offshore wind power tower, its structure is as Figure 1 ~ Figure 3 As shown, it mainly includes a damping cavity unit 1, a liquid 2, a thin steel sheet 3, a baffle 4, a friction material 5, a buffer material 6, a heater 7, a liquid pipe 8, a hydraulic device 9, and a spring 10.
[0030] The damping cavity unit 1 is divided into 4 layers, and the damping cavity of each layer is an isosceles trapezoid, divided into the left area, the middle area and the right area. The left area and the right area are filled with liquid 2 but cannot be filled. The damping cavity unit 1 is fixed to the wind power tower structure through a spring 10. Each damping cavity has a built-in thin steel sheet 3 and a baffle 4, which can be fixed in the damping cavity by welding, and are evenly arranged at an equal angle. The specific number can be obtained through experiments. The left and right areas of this embodiment are both Set 3 thin stee...
