In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced without some of these specific details.

In the drawings and the following description, at least some well-known structures and techniques have not been shown in detail in order to avoid unnecessarily obscuring the present application; also, the dimensions of some of the structures may be exaggerated for clarity. Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

The following description is given with the directional terms as they are used in the drawings and is not intended to limit the specific configurations of the damping device, the damping system, the tower and the wind turbine generator set of the present application. In the description of the present application, it is also to be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, e.g., as being either fixedly connected, detachably connected, or integrally connected; can be directly connected or indirectly connected. The specific meaning of the above terms in the present invention can be understood as appropriate to those of ordinary skill in the art.

For better understanding of the present application, the damping device 10, the damping system 20, the tower 1 and the wind turbine generator set according to the embodiment of the present application will be described in detail with reference to fig. 1 to 8.

As shown in fig. 1, the wind turbine generator set provided by the embodiment of the present application includes a tower 1, a nacelle 2, a generator 3, and an impeller 4. The tower 1 is connected to a fan foundation, the nacelle 2 is arranged at the top end of the tower 1, and the generator 3 is arranged on the nacelle 2. In some examples, the generator 3 may be located outside the nacelle 2, although in some examples, the generator 3 may also be located inside the nacelle 2. The impeller 4 includes a hub 401 and a plurality of blades 402 connected to the hub 401. The impeller 4 is connected with the rotor of the generator 3 through the hub 401, and then drives the rotor to rotate relative to the stator, so that the power generation requirement of the wind driven generator 3 group is realized.

Whether it is an onshore wind park or an offshore wind park, the park external environment is extremely complex and is accompanied by extreme uncertainty. These factors constitute various corresponding excitation sources in the operation of the wind turbine generator system, including external excitation and self-excitation, such as external uncertain wind load, irregular and recyclable wave load, imbalance of the impeller 4 itself, rotation of the impeller 4 itself, and the like. The input of these certain and uncertain excitation sources causes various uncertainties in the operating characteristics of the wind turbine generator system and some abnormal behavior, among which the most intuitive response is the vibration of the wind turbine generator system. The vibration generator set is corresponding to the vibration in the front-back direction and the left-right direction under the action of external excitation, and the vibration response directly causes the shutdown protection of the generator set, so that the loss of generated energy can be caused.

Therefore, in order to suppress the action vibration of the wind generating set from an external excitation source and to protect the wind generating set from shutdown, the wind generating set provided by the embodiment of the present application further includes a damping system 20, and the damping system 20 may be disposed on the tower 1 or, of course, may also be disposed on the nacelle 2. The embodiment of the present application will be described in detail by taking an example in which the damping system 20 is provided in the tower 1 and is a component of the tower 1.

As shown in fig. 2, the tower frame 1 provided in the embodiment of the present application includes a barrel body 30 and a damping system 20, the barrel body 30 includes a barrel wall 31 enclosing to form a hollow cavity, a mounting platform 32 disposed in the hollow cavity and connected to the barrel wall 31, and an adapter platform 33, the mounting platform 32 and the adapter platform 33 are disposed at an interval in an axial direction Y of the barrel body 30, and a plug hole is disposed in the mounting platform 32. The damping system 20 is disposed within the hollow cavity of the cartridge body 30 and is connected to the mounting platform 32 and the adaptor platform 33. The damping system 20 can inhibit the tower 1 from vibrating under the action of an external excitation source, so that the safe operation of the wind generating set is ensured.

As shown in fig. 3, the damping system 20 provided by the embodiment of the present application includes a damper 21 and a buffer device 10, the damper 21 includes a swing member 211, a mass 212 connected to the swing member 211, and a collision disk 213 connected to the mass 212, and the mass 212 and the collision disk 213 can swing synchronously with the swing member 211. The buffer device 10 is located on the swing path of the swing component 211, the mass 212 and the collision disk 213 synchronously swing along with the swing component 211 in the hollow cavity of the cylinder body 30, and the collision disk 213 is located in the insertion hole of the mounting platform 32 and can be in collision contact with the buffer device 10.

As shown in fig. 3 to 5, in order to better satisfy the buffering effect on the swinging component 211, the embodiment of the present application further provides a new buffering device 10, which includes a limiting ring 11 and a buffering member 12. The spacing ring 11 has an annular base body, the buffer member 12 is disposed on the spacing ring 11, the buffer member 12 includes a plurality of elastic components 121 sequentially distributed along a circumferential direction X of the spacing ring 11, and each elastic component 121 is at least partially disposed in the spacing ring 11 and detachably connected to the spacing ring 11.

The elastic component 121 has compressibility and can deform to a certain extent under the action of external force, and when the swing component 211 collides with the elastic component 121, the kinetic energy of the swing component 211 can be effectively absorbed, so that the impact force of the swing component 211 on the tower 1 is reduced, and the normal operation of the wind generating set is ensured.

Since the tower 1 may have a larger number of times of impact on one part of the elastic members 121 than another part of the elastic members 121 during operation, the elastic members 121 with a larger number of impacts may be damaged more frequently. Therefore, the buffering device 10 adopts the structure that the plurality of elastic parts 121 are detachably connected with the limiting ring 11, so that the seriously damaged elastic parts 121 can be replaced conveniently without replacing all the elastic parts 121, the service life of the buffering device 10 is prolonged, and the maintenance cost of the buffering device 10 is saved.

Further, the position of the elastic component 121, which is most vulnerable to damage, of the tower 1 can be obtained according to different situations of the position of the tower 1 and according to accumulated experience or limited experimental results, and a part of the elastic component 121 is made of a material more resistant to impact than other parts of the elastic component 121, so as to reduce the number of times of replacing the elastic component 121, thereby prolonging the service life of the damping device 10 and saving the cost of the damping device 10.

As an alternative implementation manner, the buffering device 10 provided in the embodiment of the present application has a plurality of elastic members 121 uniformly distributed in the circumferential direction X, and the minimum distance between every two adjacent elastic members 121 is equal.

The plurality of elastic members 121 are uniformly distributed in the circumferential direction X to ensure that the oscillating member 211 of the damper 21 can be oscillated in any direction to contact the elastic members 121 to ensure the effectiveness of the shock absorbing device 10.

Further, the minimum distance between every two adjacent elastic members 121 is equal, and it can be understood that every two adjacent elastic members 121 are arranged more compactly in the circumferential direction X to improve the effectiveness of the cushioning device 10.

Referring to fig. 5, as an alternative implementation manner, the buffering device 10 provided in the embodiment of the present application further includes first fastening members 13, and each elastic member 121 is detachably connected to the limiting ring 11 through the first fastening members 13.

Each elastic part 121 is detachably connected with the limiting ring 11, so that the assembly, replacement and maintenance of the buffering device 10 are more convenient.

Alternatively, the number of the first fastening members 13 may be one, or two or more, and may be set according to the size and shape of the elastic member 121.

Referring to fig. 5 to 8, as an optional embodiment, the buffering member 12 further includes a buffering plate 122, and a side of each elastic component 121 facing away from the limiting ring 11 is connected to the buffering plate 122 in the radial direction Z of the limiting ring 11.

When the swing member 211 of the damper 21 collides with the elastic member 121, the damping plate 122 is disposed, and the kinetic energy of the damper 21 is transmitted to the elastic member 121 through the damping plate 122, so that the compression deformation of the elastic member 121 can be reduced, and the frequency of damage and replacement of the elastic member 121 can be reduced, thereby saving the cost of the damping device 10. In addition, the arrangement of the buffer plate 122 can uniformly disperse the kinetic energy of the damper 21 to the elastic member 121, thereby preventing the elastic member 121 from being locally subjected to a large impact force to affect the service life.

Alternatively, the buffer plate 122 may be a rigid plate or a flexible plate. When the buffer plate 122 is a flexible plate and has a certain compressive deformation capability, it can be elastically deformed when being impacted by the swing member 211 of the damper 21, and absorbs kinetic energy through deformation, so as to reduce the impact on the elastic member 121. The flexible plate and the elastic member 121 absorb a large amount of kinetic energy together, so that the influence on the tower 1 is reduced, and the tower 1 is protected.

In some optional embodiments, the buffering device 10 provided in this application embodiment includes a tire 1211, an axis of the tire 1211 extends in a radial direction Z of the stop collar 11, the tire 1211 includes an inner wall 1211a, an outer wall 1211b and a sidewall 1211c connected between the inner wall 1211a and the outer wall 1211b, the inner wall 1211a is attached to the stop collar 11 and detachably connected to the stop collar 11, and a buffering plate 122 is connected to a side of the inner wall 1211a facing away from the stop collar 11 in the radial direction Z.

The elastic member 121 may include a tire 1211, and it is understood that the elastic member 121 may include a waste tire. The waste tires are used as the elastic parts 121, the elastic parts have enough capability of compression and deformation, the buffering requirement of the wind generating set is met, the elastic parts are easy to obtain, the cost is saved, meanwhile, a large number of waste tires are reused, the problems of energy waste and environmental pressure are effectively solved, and the purposes of saving energy and saving cost are achieved.

By arranging the axis of the tire 1211 extending in the radial direction Z of the stop ring 11, space can be saved better, that is, the arrangement can reduce the diameter of the stop ring 11, or can increase the swing amplitude of the swing member 211, so that the tower 1 can bear larger vibration, thereby ensuring higher performance of the wind turbine generator system.

The tire 1211 includes an inner wall 1211a, an outer wall 1211b and a side wall 1211c connected between the inner wall 1211a and the outer wall 1211b, the inner wall 1211a and the outer wall 1211b are spaced apart from each other in a radial direction Z of the retainer ring 11, the outer wall 1211b is attached to the retainer ring 11 and detachably connected to the retainer ring 11, the inner wall 1211a is connected to a buffer plate 122 on a side facing away from the retainer ring 11 in the radial direction Z, when the swing member 211 of the damper 21 collides with the buffer member 12, the buffer plate 122 transmits kinetic energy to the tire 1211 through the inner wall 1211a, the tire 1211 deforms to absorb a large amount of kinetic energy and transmits the kinetic energy to the retainer ring 11 through the outer wall 1211b, the retainer ring 11 transmits the kinetic energy to the tube body 30 through the mounting platform 32, and the tire 1211 deforms to absorb a large amount of kinetic energy, so as to reduce an influence on the tower 1 and to protect the tower 1.

In some optional embodiments, in the buffering device 10 provided in the embodiments of the present application, the buffering plate 122 is in a strip shape, and an orthographic projection of the buffering plate 122 on the tire 1211 covers a center of the tire 1211.

Since the buffer plate 122 has a strip shape, that is, the buffer plate 122 includes a plate-shaped structure having a certain length. When the swing component 211 of the damper 21 collides with the buffering member 12, the kinetic energy of the damper 21 is transmitted to the tire 1211 through the buffering plate 122, and the buffering plate 122 has a certain length, so the kinetic energy is uniformly dispersed along the length direction of the buffering plate 122 and then transmitted to the inner wall 1211a, the side wall 1211c and the outer wall 1211b of the tire 1211, thereby preventing the tire 1211 from being damaged due to uneven pressure intensity born by a local area of the tire 1211 due to the particularity of the shape of the tire 1211, and further effectively reducing the cost of the buffering device 10.

Further, in order to make the elastic member 121 receive more uniform impact kinetic energy, when the elastic member 121 is disposed for the tire 1211, the orthographic projection of the buffering plate 122 on the tire 1211 covers the center of the tire 1211, that is, the buffering plate 122 is disposed at a position beyond the diameter of the tire 1211, so as to ensure that the tire 1211 can receive more uniform impact kinetic energy, and the probability of damage is reduced.

Optionally, the cushioning device 10 further includes a second fastener 14, and the inner wall 1211a of the tire 1211 is detachably connected to the cushioning plate 122 by the second fastener 14.

The buffer plate 122 is detachably connected to the tire 1211, so that the assembly, replacement and maintenance of the buffer device 10 are more convenient. Optionally, the two can be detachably linked by the second fastener 14, and of course, a through hole can be provided at one end of the two close to each other, and a detachable connection manner of a bolt is adopted.

Alternatively, the number of the second fastening members 14 may be one, or two or more, and may be set according to the size and shape of the tire 1211.

Since the air cells 1213 have compressibility, the kinetic energy of the rocking element 211 can be absorbed by the deformation of the air cells 1213, satisfying the performance requirements of the elastic element 121.
