[0001] Cross-reference to related applications

[0002] The present application claims priority to Chinese Patent Application No. 202010469339.1, filed May 28, 2020, entitled “Damping Integrated Device, Damper and Wind Turbine Generator”, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the technical field of damping, in particular to a damping integrated device, a damper and a wind turbine generator. BACKGROUND

[0004] A damper is a device that provides resistance to motion and dissipates kinetic energy. Energy dissipation by damping has been applied in aerospace, aviation, military, wind power and other industries.

[0005] In the field of wind power technology, the tower is the support structure of the wind turbine generator, and its structural safety and stability are related to the safety performance of the entire wind turbine generator. With the continuous increase of the capacity of the wind turbine generator, the height of the tower is also increasing, and the frequency of the tower is decreasing, which makes the tower vibration problem more and more prominent. In order to ensure the safe and stable operation of the tower and the entire machine, a damper needs to be installed on the tower to suppress the vibration of the tower and ensure the safe operation of the wind turbine generator.

[0006] At present, there are many devices for damping the tower, and the tuned mass damper technology is mature and reliable, and is widely used in high-rise buildings, bridges and other fields. Among them, the tuned mass damper of high-rise structures such as the tower of the wind turbine generator mainly uses a mass block as the main damping body, and through the swing inertia force of the mass block and its damping energy dissipation device during the vibration of the tower, the purpose of damping the unit is achieved. Although this kind of damper can achieve the effect of damping, it also has corresponding disadvantages, mainly manifested in that the frequency adjusting parts, damping parts and the like are separately designed and independent of each other, distributed at different positions of the damper, and there are respective interfaces between the damper and the environment applied to the damper such as the tower, the structure design is relatively complex, and at the same time, the frequency adjusting parts, damping parts and the like are scattered at different positions, which is not conducive to maintenance.

[0057] Features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that the present application can be practiced without some or all of these specific details. The description of the embodiments is merely illustrative of the present application and is not intended to limit the present application, as is apparent to one of ordinary skill in the art.

Also, in the following description and in the claims, the terms "include" and "have" are intended to be inclusive in a manner similar to the term "comprising" as an open transition term without precluding any additional or other elements. Furthermore, the description herein of certain examples of implementations of the present application has been presented for purposes of clarity and

[0058] The orientation words appearing in the following description are the directions shown in the drawings, and are not intended to limit the specific structure of the damping integrated device, the damper and the wind turbine generator set of the present application. In the description of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "mounting" and "connection" should be understood broadly, for example, can be fixed connection, or detachable connection, or integrally connected; can be directly connected, or indirectly connected. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0059] In order to better understand the present application, the damping integrated device, the damper and the wind turbine generator set according to the embodiments of the present application will be described in detail below in conjunction with FIGS. 1 to 15.

[0060] Please refer to FIG. 1 to FIG. 3, the embodiment of the application provides a wind turbine, comprising a tower 2, a nacelle 3, a generator 4 and a rotor 5, the nacelle 3 is arranged at the top of the tower 2, the generator 4 is arranged in the nacelle 3, which can be located in the interior of the nacelle 3, of course, can also be located outside the nacelle 3. The rotor 5 includes a hub 5a and a plurality of blades 5b connected to the hub 5a, the rotor 5 is connected to the rotor of the generator 4 through the hub 5a. When the wind acts on the blade 5b, the entire rotor 5 and the rotor of the generator 4 are driven to rotate, so as to convert wind energy into electrical energy.

[0061] In order to ensure the safe operation of the wind turbine, the wind turbine provided by the embodiment of the application further comprises a damper 1, which is used to suppress the vibration of the tower 2 and other components of the wind turbine, so as to ensure the safe operation of the wind turbine. In some optional embodiments, the damper 1 can be arranged in the interior of the tower 2.

[0062] Please continue to refer to FIG. 2 and FIG. 3, the embodiment of the application further provides a damper 1, the damper 1 comprises a damping body part 200 and a damping integrated device 100, the damping integrated device 100 is connected with the damping body part 200.

[0063] In some optional embodiments, the damping body part 200 can comprise a swing arm 200a and a first mass block 200b connected to the swing arm 200a. Optionally, one end of the swing arm 200a can be connected with the first mass block 200b, and the other end can be connected to the tower 2. In some optional examples, the other end of the swing arm 200a can be connected to the tower platform and other structures in the interior of the tower 2. Through the swing arm 200a, the kinetic energy of the vibration of the component to be damped, such as the tower 2, can be obtained, so as to drive the first mass block 200b to swing.

[0064] Since the damper 1 needs to provide frequency modulation, damping and other requirements to the component to be damped, such as the tower 2, in the traditional damper, the components for realizing the frequency modulation function and the components for realizing the damping function are independently arranged and distributed at different positions of the damper. Due to the small space in the interior of the tower 2, the structure form of the traditional damper can introduce more interference possibilities. For example, the interference risk between the components of the damper and the related accessories in the tower, such as the ladder, etc., causes the structure design of the damper to be relatively complex. At the same time, the components such as the frequency modulation components and the damping components are scattered at different positions, and there are respective interfaces between the damper and the environment to which the damper is applied, such as the tower 2, which has many interfaces and is not conducive to maintenance.

[0065] Based on this, the damping integrated device 100 can make the damper 1 meet the frequency adjustment and damping requirements at the same time, and the structure design is simple and easy to maintain. At the same time, the damping integrated device 100 can be produced and sold as an independent component, and of course, in some examples, the damping integrated device 100 can also be used in the damper 1 of the above-mentioned embodiments and as a component of the damper 1.

[0066] Please refer to Figures 4 to 6, the damping integrated device 100 provided by the embodiments of the present application includes a base body 10, a frequency adjustment component 20, a first connecting piece 30 and a damping component 40. The base body 10 has a predetermined length and includes an inner cavity 10a extending along the length direction X. The frequency adjustment component 20 is arranged in the inner cavity 10a, and the frequency adjustment component 20 includes an elastic piece 21 and an adapter 22. The elastic piece 21 is connected to the base body 10 at one end in the length direction X and connected to the adapter 22 at the other end. The first connecting piece 30 extends into the inner cavity 10a and at least partially protrudes from the base body 10 in the length direction X. The first connecting piece 30 is connected to the adapter 22 and can move relative to the base body 10, so that the elastic piece 21 can stretch and contract in the length direction X. The damping component 40 is arranged in the inner cavity 10a, and the damping component 40 is connected to the adapter 22 and at least partially abuts against the inner wall of the base body 10. The damping component 40 is used to absorb the kinetic energy of the first connecting piece 30.

[0067] The damping integrated device 100 provided by the embodiments of the present application includes the frequency adjustment component 20 and the damping component 40, and integrates the frequency adjustment component 20 and the damping component 40 in the inner cavity 10a of the base body 10. When the damping integrated device 100 is in use, the part of the first connecting piece 30 protruding from the base body 10 can be connected to the damping body 200 in rotation, and the end of the base body 10 away from the first connecting piece 30 can be connected to the component to be damped, such as the tower 2, or other components of the damping body 200. Since the elastic piece 21 and the damping component 40 are both connected to the first connecting piece 30 through the adapter 22, and are respectively connected to or abut against the base body 10, when the component to be damped vibrates, the frequency of the damper 1 can be adjusted through the frequency adjustment component 20, and the kinetic energy of the vibration transmitted to the first connecting piece 30 can be absorbed through the damping component 40, achieving the damping effect. That is, the damping integrated device 100 has both frequency adjustment and damping characteristics. The frequency adjustment component 20 and the damping component 40 are integrated in the inner cavity 10a inside the base body 10, which makes the overall structure of the damping integrated device 100 compact and easy to maintain while meeting the requirements of frequency adjustment and damping. At the same time, the damping component 40 and the frequency adjustment component 20 are both connected to external components through the first connecting piece 30 and the base body 10, which has fewer interfaces and strong versatility.

[0068] As an optional implementation, the elastic member 21 provided in the above embodiments comprises two or more springs 211 which are spaced apart and extend along the length direction X, and each spring 211 is connected to the base body 10 at one end and connected to the adapter 22 at the other end. By limiting the elastic member 21 to comprise two or more springs 211, the overall structure of the elastic member 21 is simple, and the frequency modulation characteristics of the damping integrated device 100 are better optimized, so that the damping integrated device 100 can better ensure the frequency modulation requirements of the damper 1 when applied to the damper 1.

[0069] As an optional implementation, at least one spring 211 can be detachably connected to the base body 10 and the adapter 22, respectively. Through the above arrangement, the number of springs 211 included in the elastic member 21 can be changed as needed, thereby better ensuring the frequency modulation requirements of the damping integrated device 100, so that the damper 1 to which it is applied can adjust the number of springs 211 according to the frequency of the component to be damped, such as the tower 2, so that the frequencies of the two are kept consistent as much as possible, and the damping effect is better optimized.

[0070] As an optional implementation, the adapter 22 can be provided with a plurality of first hanging rings 20a on the surface facing the elastic member 21 in the length direction X, the inner cavity 10a of the base body 10 can be provided with a second hanging ring 20b corresponding to each first hanging ring 20a on the surface facing the adapter 22, and one end of the spring 211 facing the first hanging ring 20a is hooked to the first hanging ring 20a and detachably connected, and the other end of the spring 211 facing the second hanging ring 20b is hooked to the second hanging ring 20b and detachably connected. Through the above arrangement, the detachable connection of the spring 211 can be better ensured.

[0071] In some optional embodiments, each spring 211 can be detachably connected to the base body 10 and the adapter 22, respectively. Through the above arrangement, not only can the frequency of the damper 1 to which the damping integrated device 100 is applied be better adjusted to be closer to that of the component to be damped, thereby ensuring the damping effect. At the same time, the above arrangement also facilitates the replacement of the spring 211, thereby ensuring that the spring constant of the spring 211 always meets the frequency modulation requirements of the damping integrated device 100.

[0072] As an optional implementation, the damping integrated device 100 provided in the above embodiments can further comprise a transition plate 20c, and the base body 10 can be connected to the springs 211 of the elastic member 21 through the transition plate 20c. When the transition plate 20c is included, the second hanging ring 20b can be indirectly connected between the transition plate 20c and the base body 10. The provision of the transition plate 20c facilitates the installation of the elastic member 21, and at the same time, makes the overall damping integrated device 100 easy to process and assemble, and can reduce the wear of the base body 10.

[0073] Optionally, the transition plate 20c and the adapter 22 can be plate-shaped structures and arranged opposite to each other in the length direction X, and each spring 211 can be connected between the transition plate 20c and the adapter 22.

[0074] Please continue to refer to FIGS. 4-6, as an optional embodiment, the damping integrated device 100 provided by the above embodiments includes the cylinder body 11 extending in the length direction X and the end cover 12 arranged at both ends of the cylinder body 11 in the length direction X, and the end cover 12 and the cylinder body 11 jointly enclose the inner cavity 10a. In the direction intersecting the length direction X, which can be perpendicular to the length direction X, a spacing cavity is formed between the cylinder body 11 and the frequency modulation component 20, and the damping component 40 is located in the spacing cavity. Through the above arrangement, the frequency modulation and damping requirements of the damping integrated device 100 can be better met, and the internal space of the base body 10 can be better utilized to meet the integration requirements.

[0075] In some optional embodiments, in the length direction X of the base body 10, the cross section of the cylinder body 11 can be a circular ring, the shape of the end cover 12 matches the shape of the cylinder body 11, and the two end covers 12 in the length direction X can be respectively detachably connected with the cylinder body 11. Of course, in some examples, one of the end covers 12 can be fixedly connected with the cylinder body 11 or be an integrated structure, and the other end cover 12 can be detachably connected with the cylinder body 11. Through the above arrangement, the installation of the frequency modulation component 20 and the damping component 40 can be facilitated. Optionally, one of the end covers 12 can be matched with the first connecting piece 30, and the end cover 12 matched with the first connecting piece 30 can be detachably connected with the cylinder body 11.

[0076] In some optional embodiments, the damping integrated device 100 provided by the above embodiments includes the mounting piece 41, the support piece 42, and the magnet 43. The mounting piece 41 is connected to the adapter 22 at one end in the length direction X, the magnet 43 is arranged to face the cylinder body 11 and is connected with the mounting piece 41, and the support piece 42 is supported between the mounting piece 41 and the cylinder body 11 to form an air gap 90 between the magnet 43 and the cylinder body 11. The first connecting piece 30 can drive the magnet 43 to move relative to the base body 10 along the length direction X and generate an induced eddy current in the base body 10 through the adapter 22.

[0077] The damping component 40 adopts the above structure, so that when the component to be damped, such as the tower 2, vibrates, the first connecting member 30 is connected with the first mass block 200b of the damping body 200, the vibration of the component to be damped drives the first mass block 200b to move the first connecting member 30 along the length direction X, and then the magnet 43 moves relative to the cylinder 11, so that the inside of the cylinder 11 generates an induced eddy current to absorb the kinetic energy of the first connecting member 30 and convert it into heat energy, thereby reducing the vibration of the component to be damped. Moreover, in this process, the springs 211 of the frequency adjustment component are stretched or compressed with the movement of the first connecting member 30 to adjust the frequency of the damper 1.

[0078] In some optional embodiments, the damping integrated device 100 provided by the above embodiments has a cylindrical mounting member 41 surrounding the elastic member 21, and the adapter 22 is connected with the mounting member 41 and seals one end of the mounting member 41 in the length direction X. The magnet 43 includes a plurality of magnetic blocks 431, and at least part of the magnetic blocks 431 are distributed along the length direction X. Through the above arrangement, the damping integrated device 100 can meet the frequency adjustment and damping requirements, and has a more compact structure, and can better adjust the frequency of the damper 1 and consume the kinetic energy of the first mass block 200b acting on the first connecting member 30, thereby ensuring the damping effect.

[0079] As an optional implementation, according to the damping requirement, at least part of the magnetic blocks 431 can be distributed along the outer ring surface of the mounting member 41.

[0080] In some optional embodiments, the mounting member 41 and the adapter 22 can be an integrated structure, which has high connection strength and is easy to install.

[0081] In some optional embodiments, the mounting member 41 of the damping integrated device 100 provided by the above embodiments can be coaxially arranged with the cylinder 11 of the base body 10. When the mounting member 41 moves relative to the cylinder 11 with the first connecting member 30, the eddy current generated on the cylinder 11 is more uniform, which can better convert the kinetic energy of the first connecting member 30 into heat energy on the cylinder 11, thereby ensuring the damping effect.

[0082] As an optional implementation, the damping integrated device 100 provided by the above embodiments comprises two or more first rollers 422, which are spaced apart and respectively rotatably connected to the mounting member 41. By adopting the above structure, the formation of the air gap 90 between the magnet 43 and the cylinder 11 is ensured, and the rolling friction between the support member 42 and the inner wall of the base 10 is also ensured, which can ensure the smooth movement of the mounting member 41 driven by the first connecting member 30, and better absorb the kinetic energy of the first connecting member 30, thereby ensuring the damping effect of the damping integrated device 100 and the damper 1 used thereby.

[0083] Optionally, the magnet 43 is provided with a first roller 422 at each end in the length direction X. Optionally, two or more first rollers 422 are arranged in the circumferential direction of the mounting member 41, which can further ensure the uniformity of the air gap 90 formed between the magnet 43 and the cylinder 11.

[0084] In some optional embodiments, a recess (not shown in the figure) can be arranged on the outer circumferential surface of the cylinder 11, so that at least part of the first roller 422 extends into the recess and is rotatably connected between the cylinder 11 and the rotating shaft or the like.

[0085] Please continue to refer to FIGS. 4 to 6. As an optional implementation, the damping integrated device 100 provided by the above embodiments is provided with a first opening 111 on the cylinder 11, and the first opening 111 is in communication with the inner cavity 10a.
