[0038] This embodiment provides a tuned mass damping device that eliminates the need for a swing arm, saving space and providing high safety. Furthermore, its applicable frequency can be adjusted within the design range by the radius of curvature of the curved guide rail. The eddy current component can avoid mechanical friction and extend the life of the tuned mass damping device.

[0039] Specifically, such as Figures 1 to 4 As shown, the tuned mass damping device includes a guide rail assembly 1, an energy dissipation unit 2, and a mass unit 3. The guide rail assembly 1 includes a curved guide rail 12, both ends of which can be connected to the engineering structure. The curved guide rail 12 is in the shape of a standard circular arc and its radius of curvature is adjustable. The energy dissipation unit 2 includes an eddy current assembly 21, which is disposed on the curved guide rail 12 and can slide along the curved guide rail 12 to generate eddy current damping force. The mass unit 3 includes a mass block, which is fixed above or below the eddy current assembly 21.

[0040] It should be noted that the curve guide rail 12 is a standard circular arc, which means that the inner diameter and the outer diameter of the curve guide rail 12 are standard circular arcs in the front view of the curve guide rail 12.

[0041] Based on the above design, the two ends of the curve guide rail 12 can be connected with the fan tower and other engineering structures, the curve guide rail 12 is a standard circular arc with adjustable radius of curvature; the energy dissipation unit 2 includes an eddy current assembly 21, the eddy current assembly 21 is arranged on the curve guide rail 12 and can slide along the curve guide rail 12 to generate an eddy current damping force; the mass unit 3 includes a mass block, the mass block is fixed above or below the eddy current assembly 21, and the eddy current assembly 21 can drive the mass block to slide along the curve guide rail 12. Since the curve guide rail 12 is a standard circular arc, it is an arc surface model similar to the pendulum model principle, which can achieve the same simple harmonic period as the traditional horizontal pendulum tuned mass damper, so the mass block and the engineering structure are tuned at the resonance frequency, the mass block and the engineering structure move in opposite directions, and the vibration energy is absorbed by the eddy current assembly 21, thereby solving the horizontal vibration problem of the engineering structure. Compared with the traditional pendulum tuned mass damper, the tuned mass damper device does not need to be suspended, i.e. the setting of the swing arm is omitted, thereby saving space and being safe, and the applicable frequency can be adjusted within the design range by the radius of curvature (inner radius of curvature R1 and outer radius of curvature R2) of the curve guide rail 12. On the other hand, the eddy current assembly 21 generates eddy current damping according to the Lenz law, which can avoid mechanical friction and prolong the service life of the tuned mass damper device.

[0042] Optionally, the guide rail assembly 1 further includes two connecting ear plates 11, the curve guide rail 12 is connected with the engineering structure through the two connecting ear plates 11, in the embodiment, the connecting ear plate 11 is a square plate, and a connecting hole is arranged on the direction plate, and a bolt is arranged through the connecting hole to fixedly connect the connecting ear plate 11 and the engineering structure such as the fan tower.

[0043] Optionally, the energy dissipation unit 2 includes a main frame 22 and two groups of eddy current assemblies 21, the curve guide rail 12 is movably arranged in the main frame 22, the two groups of eddy current assemblies 21 are respectively connected with the main frame 22 and are respectively located on both sides of the curve guide rail 12 in the width direction, and the mass block is fixed above or below the main frame 22, i.e. one mass block can be fixed to the outer wall of the upper base plate of the main frame 22, or one mass block can be fixed to the outer wall of the lower base plate of the main frame 22, or two mass blocks are arranged on the outer wall of the upper base plate and the outer wall of the lower base plate of the main frame 22 respectively; the eddy current assembly 21 is located between the upper and lower base plates of the main frame 22, the main frame 22 is used for fixing the eddy current assembly 21, and thus the mass block is also fixed; the two groups of eddy current assemblies 21 are arranged to increase the eddy current damping.

[0044] Further, the two side walls of the width direction of the curved guide rail 12 are provided with end face teeth 122, the eddy current assembly 21 comprises a conductor cylinder 211, a gear housing 216 and a first magnetic steel 212, the gear housing 216 is rotationally connected with the main frame 22, the gear housing 216 can be engaged with the end face teeth 122 to make the gear housing 216 roll on the curved guide rail 12, the conductor cylinder 211 is fixed to the inner side wall of the gear housing 216, and the first magnetic steel 212 is located in the conductor cylinder 211 and fixed with the main frame 22. In the embodiment, the first magnetic steel 212 is a plurality of evenly distributed magnetic steel blocks. When the main frame 22 slides along the curved guide rail 12, the gear housing 216 drives the conductor cylinder 211 to rotate, and since the first magnetic steel 212 is fixed with the main frame 22, the conductor cylinder 211 cuts the magnetic induction lines in the rotating process, thereby generating an eddy current damping force. Compared with the conventional pendulum eddy current TMD, the ordinary relative translation of the energy dissipation unit 2 is converted into the rotary motion of the eddy current assembly 21 through gear transmission, and to increase the upper limit of the number of magnetic steel blocks, it is only necessary to increase the structural size of the eddy current assembly 21, which is independent of the size of the mass block, thereby improving the upper limit of the damping coefficient and the adjustment range, and the damping coefficient can be adjusted on site. It only needs to disassemble the eddy current assembly 21, and increase or remove the magnetic steel blocks, thereby reducing the difficulty of increasing or reducing the magnetic steel blocks on site.

[0045] Further, the eddy current assembly 21 further comprises a center shaft 215 and a magnetic steel frame 213, both ends of the center shaft 215 are connected with the main frame 22, the gear housing 216 is rotationally connected with the center shaft 215 through a bearing 214, and the magnetic steel frame 213 is fixed to the center shaft 215. The rotational connection between the gear housing 216 and the main frame 22 is realized through the center shaft 215 and the bearing 214, which has simple structure and high stability; the first magnetic steel 212 is fixed with the center shaft 215 and the magnetic steel frame 213, and the magnetic steel frame 213 is used for fixing the first magnetic steel 212.

[0046] It should be noted that the two ends of the center shaft 215 are respectively in force-transmitting connection with the upper and lower base plates of the main frame 22, which can be square shaft and square hole cooperation, or other force-transmitting cooperation such as flat key cooperation, spline cooperation, etc.

[0047] Optionally, the upper and lower sides of the curved guide rail 12 are each provided with a sliding groove 124, and the energy dissipation unit 2 further comprises a plurality of roller sets, the roller sets correspond to the sliding grooves 124 one by one, the roller sets are fixed to the inner walls of the upper and lower base plates of the main frame 22, and the roller sets can roll in the sliding grooves 124. The main frame 22 slides along the curved guide rail 12 through the sliding groove 124 and the roller set mode, which has small resistance and reduces friction.

[0048] Furthermore, two sliding grooves 124 are provided on the upper and lower sides of the curved guide rail 12, and the two sliding grooves 124 are spaced apart along the width of the curved guide rail 12. That is, two sliding grooves 124 and two sets of rollers are provided on the upper and lower sides respectively, which improves the stability of the main frame 22 during the sliding process.

[0049] like Figures 5 to 9 As shown, the energy dissipation unit 2 also includes two conductor plates 123 and a second magnet 23. The two conductor plates 123 are respectively laid on the upper and lower sides of the curved guide rail 12 and located between the two corresponding sliding grooves 124. The second magnet 23 corresponds one-to-one with the conductor plates 123. The second magnet 23 is fixed to the main frame 22 and is positioned directly opposite to the conductor plates 123. Specifically, the second magnet 23 is fixed to the inner wall of the upper and lower base plates of the main frame 22. The second magnet 23 moves with the main frame 22 (energy dissipation unit 2) and has a relative motion relationship with the conductor plates 123, cutting magnetic field lines and generating eddy current damping. The conductor plates 123 and the second magnet 23 work together as an auxiliary damping unit, together with the aforementioned eddy current component 21, which is the main damping unit, to serve as the energy dissipation unit 2, absorbing and dissipating the vibration energy of the mass block.

[0050] Furthermore, the curved guide rail 12 includes a working section and two stopping sections. The working section is in the shape of a standard circular arc, and the end face teeth 122 are located in the working section. The two stopping sections are both straight sections and are connected to the two ends of the working section respectively. When the main frame 22 moves in the curved motion of the working section in the middle, the main damping unit and the auxiliary damping work together to realize the energy dissipation function, so that the tuned mass damping device works normally. When the main frame 22 (energy dissipation unit 2) moves to the stopping sections at both ends, the main damping unit stops working, that is, the tuned mass damping device changes from the normal working state to the stopping state.

[0051] Specifically, the energy-consuming unit 2 also includes an elastic support 25 and a friction plate 24. The two ends of the elastic support 25 are respectively connected to the second magnet 23 and the main frame 22. The friction plate 24 is provided on the side of the second magnet 23 away from the elastic support 25. The elastic support 25, the second magnet 23, the friction plate 24 and the conductor plate 123 are arranged in a projection overlap. A copper wire winding 13 is wound on the stop section. When the wind turbine tower and other engineering structures encounter extreme working conditions and generate overtravel displacement, the movement range of the energy dissipation unit 2 changes from the working section to the stopping section. Since the copper wire winding 13 can be energized to generate an electromagnetic field, the electromagnetic field generates a huge attraction force on the second magnet 23, causing the elastic support 25 to deform and forcing the friction plate 24 to contact the conductor plate 123, generating frictional resistance. At the same time, the gap between the second magnet 23 and the conductor plate 123 is greatly reduced (i.e., reduced to the thickness of the friction plate 24), and the eddy current damping force generated by the second magnet 23 is greatly increased. The energy dissipation unit 2 is braked by the frictional resistance and the eddy current damping force to prevent it from impacting and colliding with the wind turbine tower and other engineering structures, thereby causing damage to the tower.

[0052] In the embodiment, the connection between the working section and the stop section is provided with a photoelectric switch 121, which is used to control the on-off of the power supply of the copper winding 13.

[0053] Specifically, the end of the stop section away from the working section is provided with a wire hole 125, through which the external power supply wire is inserted into the inside of the curved guide rail 12, so that the power supply wire is connected with the photoelectric switch 121 embedded in the side wall of the curved guide rail 12. Optionally, each group of the roller sets includes a main roller member 26 and two auxiliary roller members 27, which are arranged in the length direction (horizontal length direction) of the curved guide rail 12, and the main roller member 26 is located between the two auxiliary roller members 27, and the two auxiliary roller members 27 are symmetrical about the main roller member 26.

[0054] Further, the main roller member 26 includes a first fixed seat 261 and a main roller 262, the first fixed seat 261 is fixed to the main frame 22, and the main roller 262 is rotatably installed on the first fixed seat 261. The auxiliary roller member 27 includes a second fixed seat 271, a moving seat 272, a compression spring 273 and an auxiliary roller, the second fixed seat 271 is fixed to the main frame 22, the two ends of the compression spring 273 are connected with the second fixed seat 271 and the moving seat 272 respectively, and the auxiliary roller is rotatably installed on the moving seat 272. The auxiliary roller can always be in contact with the toothed guide rail during the movement of the energy consumption unit 2 through the compression spring 273, that is, even during the movement from the working section to the horizontal part of the stop section.

[0055] In the actual arrangement of the tuned mass damper, as shown in Figure 10 in order to realize the suppression of the vibration in the entire horizontal plane of the fan tower and other engineering structures, the above-mentioned tuned mass dampers can be arranged vertically two by two, that is, the horizontal movement of the fan tower and other engineering structures in any direction can be decomposed into the movement in the length direction of two tuned mass dampers.

[0056] Obviously, the above-mentioned embodiments of the present application are only examples for the purpose of clear illustration, and are not intended to limit the embodiments of the present application. Those skilled in the art can make various obvious changes, readjustments and substitutions without departing from the protection scope of the present application. It is unnecessary and impossible to enumerate all the embodiments. Any modification, equivalent substitution and improvement within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
