Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine generator sets, and specifically relates to a vibration damping mechanism for wind turbine generator sets. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current.

[0003] Publication No. CN219035445U discloses a vibration damping mechanism for a wind turbine generator set. This patent achieves the purpose of vibration damping by adding two sets of vibration damping mechanisms to the bottom of the generator set. However, the installation stability of the vibration damping mechanism is worse than that of the existing bolt installation when it is set at the bottom of the generator set. Moreover, the vibration of the generator set mainly comes from the high-frequency slight swaying of the body from side to side. Therefore, adding a vibration damping structure at the bottom cannot effectively achieve the vibration damping effect. Thus, there is room for improvement in actual use. Utility Model Content

[0004] The purpose of this utility model is to provide a vibration damping mechanism for wind turbine generator sets, so as to solve the problem mentioned in the background art that the existing vibration damping mechanisms are not effective in damping and also affect the installation stability of the generator set itself.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping mechanism for a wind turbine generator set, comprising two mounting frames, both of which are detachably fixed at their ends; a support member installed on the outer side of each mounting frame, which supports the mounting frame and allows for adaptive adjustment according to the height of the wind turbine generator set; a vibration damping component that is connected through the mounting frames; the vibration damping component includes a connector threadedly connected to the mounting frame, with both ends located on the inner and outer sides of the mounting frame; and a damping part, one end of which is movably inserted into the interior of the connector, and the other end extending towards the inner side of the mounting frame. The damping part elastically abuts against the side of the wind turbine generator set, and its periphery is seamlessly fitted with the inner wall of the connector. When the wind turbine generator experiences left-right swaying, the damping part moves, moving within the connector. The resistance between the damping part and the connector reduces the vibration of the wind turbine generator set.

[0006] Preferably, the connector includes a threaded sleeve with an air hole on its end face facing outward from the mounting bracket. The damping part and the threaded sleeve form a cavity with only a single air inlet and outlet. When the damping part moves inside the threaded sleeve, the air inside is discharged through the air hole. Since the diameter of the air hole is constant, the discharged gas content has a maximum value. When the discharged gas reaches its maximum, the moving speed of the damping part is also constant. At this time, the generator set with high-frequency vibration can be damped.

[0007] Preferably, the shock-absorbing part includes a stop post, one end of which is movably inserted into the interior of a threaded sleeve. A spring is also welded to one end of the stop post. A locking bolt is screwed into the top of the threaded sleeve, which abuts against the end of the spring, thereby limiting the position of the spring and preventing it from coming off. It also limits the position of the stop post. In use, the stop post will compress the spring and expel the gas in the cavity through the air hole. When the wind turbine is no longer in contact with the stop post, the spring will return the stop post to its initial position.

[0008] Preferably, there is no gap at the connection between the locking bolt and the threaded sleeve, and the locking bolt is located in the area where the threaded sleeve does not have threads.

[0009] Preferably, an integral connecting block is fixed to the outer side of the mounting bracket, and the support member is connected through the connecting block.

[0010] Preferably, the support member includes a support rod that passes through the connecting block, and at least two limiting nuts are sleeved on the surface of the support rod. The two limiting nuts are respectively located at the upper and lower end faces of the connecting block, thereby supporting the mounting frame. A base plate is also installed at the bottom end of the support rod, and the base plate is bolted to the bearing surface.

[0011] Preferably, threaded holes are provided at the mating end faces of the two mounting brackets, and connecting studs pass through the threaded holes. The connecting studs enable the connection between the two brackets, and at the same time, the connecting studs enable the separation connection between the two brackets, so as to make corresponding adjustments according to the width of the wind turbine generator set.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Through the design of this utility model, the two sides of the generator set can be limited and damped, which can significantly reduce the vibration generated by the wind turbine generator set during operation. In addition, this utility model can adjust its own size according to different specifications of wind turbine generator sets, and has high overall versatility. Since this utility model does not improve the bottom connection position of the wind turbine generator set, it will not affect the normal installation stability of the wind turbine generator set. Therefore, it improves many shortcomings of the existing shock absorption mechanism in use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a vibration damping mechanism for a wind turbine generator set, comprising...

[0023] Mounting bracket 100, two of them are provided, and the ends of both are detachably fixed;

[0024] Support members are installed on the outer side of each mounting frame 100 to support the mounting frame 100 and to make adaptive adjustments according to the height of the wind turbine generator set.

[0025] The vibration damping assembly is connected through the mounting bracket 100; the vibration damping assembly includes...

[0026] The connector is threaded to the mounting bracket 100, and its two ends are located at the inner and outer sides of the mounting bracket 100, respectively.

[0027] The shock absorber has one end inserted into the interior of the connector, and the other end extends toward the inside of the mounting bracket 100. The shock absorber elastically abuts against the side of the wind turbine generator set, and the periphery of the shock absorber fits seamlessly with the inner wall of the connector. When the wind turbine generator shakes from side to side, it will move the shock absorber. At this time, the shock absorber moves within the connector, and the resistance between the shock absorber and the connector reduces the vibration of the wind turbine generator set.

[0028] In this embodiment, preferably, the connector includes a threaded sleeve 200. The threaded sleeve 200 has an air hole 203 on its end face facing the outside of the mounting bracket 100. The damping part and the threaded sleeve 200 form a cavity with only a single air inlet and outlet. When the damping part moves inside the threaded sleeve 200, the air inside will be discharged through the air hole 203. Since the diameter of the air hole 203 is constant, the content of the discharged gas has a maximum value. When the discharged gas reaches the maximum, the moving speed of the damping part is also constant. At this time, the generator set with high-frequency vibration can be damped.

[0029] In this embodiment, preferably, the shock-absorbing part includes a stop post 201. One end of the stop post 201 is movably inserted into the interior of the threaded sleeve 200. A spring 204 is also welded to one end of the stop post 201. A locking bolt 202 is screwed into the top of the threaded sleeve 200. The locking bolt 202 abuts against the end of the spring 204, thereby limiting the position of the spring 204 to prevent it from coming off. At the same time, it also limits the stop post 201. In use, the stop post 201 will compress the spring 204 and discharge the gas in the cavity from the air hole 203. When the wind turbine is no longer in contact with the stop post 201, the spring 204 will rebound and restore the stop post 201 to its initial position.

[0030] In this embodiment, preferably, no gap is generated at the connection between the locking bolt 202 and the threaded sleeve 200, and the locking bolt 202 is located in the area where the threaded sleeve 200 does not have threads.

[0031] In this embodiment, preferably, an integral connecting block 101 is also fixed on the outer side of the mounting bracket 100, and the support member is connected to the connecting block 101 through the support member.

[0032] In this embodiment, preferably, the support member includes a support rod 102 that passes through the connecting block 101. At least two limiting nuts 104 are sleeved on the surface of the support rod 102. The two limiting nuts 104 are respectively located at the upper and lower end faces of the connecting block 101, thereby supporting the mounting frame 100. A base plate 103 is also installed at the bottom end of the support rod 102. The base plate 103 is installed on the bearing surface by bolts.

[0033] In this embodiment, preferably, threaded holes are provided at the end faces where the two mounting brackets 100 fit together, and connecting studs 105 pass through the threaded holes. The connection between the two is achieved by connecting studs 105, and the connection between the two can also be separated by connecting studs 105, so as to make corresponding adjustments according to the width of the wind turbine generator set.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
