In the related art, the speed increaser and the generator are connected by a coupling. When the speed of the speed increaser suddenly increases, it will drive the generator through the coupling, so that the speed of the generator suddenly increases, which will cause the generator to overload and easily cause damage to the generator.

DETAILED DESCRIPTION

[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0019] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0020] like Figures 1 to 14 As shown, the first aspect of the present disclosure provides a power generation system of a wind turbine generator set, including a generator 10, a speed increaser 20 and a magnetic transmission mechanism 30. The generator 10 includes a power generation input shaft 11, and the speed increaser 20 includes a speed increaser output shaft 21. The magnetic transmission mechanism 30 includes an active magnetic component 31 connected to the speed increaser output shaft 21 and a driven magnetic component 32 connected to the power generation input shaft 11. The active magnetic component 31 and the driven magnetic component 32 cooperate magnetically for transmission between the generator 10 and the speed increaser 20. Magnetic transmission is used between the active magnetic component 31 and the driven magnetic component 32. Compared with the direct contact transmission using a coupling, the magnetic transmission has a stronger anti-overload capability.

[0021] Specifically, when the wind turbine 10 encounters a sudden change in wind force during use, the speed of the impeller suddenly increases, which causes the main shaft and the speed increaser 20 connected to the impeller to suddenly increase in speed. The speed increaser 20 and the generator 10 are connected through the magnetic transmission mechanism 30. When the speed of the output shaft of the speed increaser 20 suddenly increases, the magnetic balance between the active magnetic component 31 and the driven magnetic component 32 of the magnetic force coordination is broken, and the power transmission between the speed increaser 20 and the generator 10 is disconnected, thereby preventing the overload operation of the generator 10 and protecting the generator 10.

[0022] In some embodiments, the active magnetic component 31 includes a first magnetic mounting disk 311 and an active magnet 312 disposed on the first magnetic mounting disk 311, and the driven magnetic component 32 includes a second magnetic mounting disk 321 and a driven magnet 322 disposed on the second magnetic mounting disk 321, the active magnet 312 and the driven magnet 322 are arranged correspondingly, the first magnetic mounting disk 311 is installed on the speed increasing output shaft 21, and the second magnetic mounting disk 321 is installed on the power generation input shaft 11.

[0023] In the above-mentioned embodiment, the active magnet 312 and the driven magnet 322 are arranged correspondingly. When the speed increasing output shaft 21 of the speed increasing box 20 rotates, the active magnet 312 can be rotated with it, and the driven magnet 322 that cooperates with the magnetic force of the active magnet 312 also rotates with the active magnet 312, and then rotates with the power generation input shaft 11 through the second magnetic mounting disk 321, and the generator 10 starts to run.

[0024] In addition, the active magnet 312 and the driven magnet 322 can be arranged with a gap, so that the speed increaser 20 and the generator 10 can achieve contactless power transmission through the active magnetic assembly 31 and the driven magnetic assembly 32, which can reduce the wear and friction caused by direct contact of each component during the power transmission process, and reduce the vibration during the transmission process caused by wear and friction between the transmission components. So that the transmission process between the speed increaser 20 and the generator 10 is smoother.

[0025] In some embodiments, the number of the active magnet 312 and the number of the driven magnet 322 are both plural, and the multiple active magnets 312 and the multiple driven magnets 322 are arranged in a one-to-one correspondence.

[0026] In the above-mentioned embodiment, there are multiple active magnets 312, and the multiple active magnets 312 are arranged on the first magnetic mounting disk 311, and the multiple driven magnets 322 are arranged on the second magnetic mounting disk 321. When the speed increase output shaft 21 of the speed increaser 20 drives the multiple active magnets 312 installed on the first magnetic mounting disk 311 to rotate, the multiple driven magnets 322 will rotate with the multiple active magnets 312 to drive the second magnetic mounting disk 321 and the power generation input shaft 11 connected to the second magnetic mounting disk 321 to rotate, thereby enabling power generation.

[0027] It should be noted that the corresponding arrangement between the active magnet 312 and the driven magnet 322 can be constructed so that the magnetism between the opposing surfaces between the active magnet 312 and the driven magnet 322 is opposite, that is, when the active magnet 312 of the correspondingly arranged active magnet 312 and the driven magnet 322 rotates, the driven magnet 322 can follow the active magnet 312 to rotate by attracting the driven magnet 322. Of course, in other possible implementations, the polarities between the opposing surfaces between the active magnet 312 and the driven magnet 322 can be the same, and when the active magnet 312 rotates, the rotation of the driven magnet 322 is achieved by relying on the repulsive force between the active magnet 312 and the driven magnet 322, which is not limited here.

[0028] In some embodiments, the magnetic transmission mechanism 30 further includes an isolation pad 33 , which is disposed between the first magnetic mounting disk 311 and the second magnetic mounting disk 321 , and the first magnetic mounting disk 311 and the second magnetic mounting disk 321 are respectively attached to opposite sides of the isolation pad 33 .

[0029] In the magnetic transmission mechanism 30, it is usually necessary to control the gap between the corresponding active magnet 312 and the driven magnet 322. However, since the magnetic transmission is a non-contact transmission, when installing the magnetic transmission mechanism 30, the gap between the corresponding active magnet 312 and the driven magnet 322 is not easy to control. An isolation pad 33 is set between the first magnetic mounting disk 311 and the second magnetic mounting disk 321, and the first magnetic mounting disk 311 and the second magnetic mounting disk 321 are respectively attached to the isolation pad 33, so as to facilitate the control of the distance between the active magnet 312 and the driven magnet 322 when installing the active magnetic assembly 31 and the driven magnetic assembly 32.

[0030] It should be noted that the isolation pad 33 can be constructed arbitrarily according to actual needs. For example, the isolation pad 33 can be constructed as a rubber pad.

[0031] In addition, the isolation pad 33 can be bonded to the first magnetic mounting disk 311 and the second magnetic mounting disk 321 respectively, so that when the first magnetic mounting disk 311 and the second magnetic mounting disk 321 rotate synchronously, the isolation pad 33 also stably rotates synchronously with the first magnetic mounting disk 311 and the second magnetic mounting disk 321.

[0032] It should be noted that the isolation pad 33 is respectively bonded to the first magnetic mounting disk 311 and the second magnetic mounting disk 321, and the bonding between the isolation pad 33 and the first magnetic mounting disk 311 and the bonding between the isolation pad 33 and the second magnetic mounting disk 321 will not affect the overload protection capability of the magnetic transmission mechanism 30, that is, when the magnetic balance between the active magnet 312 and the driven magnet 322 of the magnetic transmission mechanism 30 is destroyed, the isolation pad 33 will also be detached from the first magnetic mounting disk 311 and the second magnetic mounting disk 321 from the bonding state.

[0033] In addition, in some embodiments, the isolation pad 33 can be a barrier between the active magnet 312 and the driven magnet 322. When the active magnet 312 and the driven magnet 322 become loose, the isolation pad 33 prevents the active magnet 312 and the driven magnet 322 from being adsorbed together, and the active magnetic component 31 and the driven magnetic component 32 can operate normally.

[0034] In some embodiments, the magnetic transmission mechanism 30 also includes a first connecting member 34 and a second connecting member 35, wherein the two ends of the first connecting member 34 are respectively connected to the speed increasing output shaft 21 and the first magnetic mounting disk 311, and the two ends of the second connecting member 35 are respectively connected to the power generation input shaft 11 and the second magnetic mounting disk 321.

[0035] In the above-mentioned embodiment, the first connecting member 34 is installed on the speed increasing output shaft 21, the second connecting member 35 is installed on the generator input shaft 11, the first magnetic mounting disk 311 is connected to the first connecting member 34, and the second magnetic mounting disk 321 is connected to the second connecting member 35. When the first magnetic mounting disk 311 and the second magnetic mounting disk 321 need to be replaced, they can be directly disassembled from the first connecting member 34 and the second connecting member 35 without the need to disassemble from the speed increasing output shaft 21 and the generator input shaft 11, thereby avoiding damage to the speed increasing output shaft 21 and the generator input shaft 11 caused by multiple disassemblies.

[0036] In addition, the first connecting member 34 and the second connecting member 35 can be arranged in any appropriate form according to actual needs. For example, the first connecting member 34 includes a first connecting cylinder 341 and a first connecting shaft 342, wherein one end of the first connecting cylinder 341 is sleeved on the speed-increasing output shaft 21, and the first connecting cylinder 341 and the speed-increasing output shaft 21 are fixed by screws; one end of the first connecting shaft 342 is inserted into the end of the first connecting cylinder 341 away from the speed-increasing output shaft 21, and the first connecting shaft 342 and the first connecting cylinder 341 are fixed by screws. The end of the first connecting shaft 342 away from the first connecting cylinder 341 is fixedly connected to the first magnetic mounting disk 311, and when the speed-increasing output shaft 21 rotates, the first magnetic mounting disk 311 is driven to rotate through the first connecting cylinder 341 and the first connecting shaft 342. The first connecting shaft 342 is inserted into the first connecting cylinder 341 . Therefore, the distance between the first magnetic mounting disk 311 and the speed increasing output shaft 21 can be adjusted by adjusting the length of the first connecting shaft 342 inserted into the first connecting cylinder 341 .

[0037] The second connecting member 35 includes a second connecting cylinder 351 and a second connecting shaft 352, wherein one end of the second connecting cylinder 351 is sleeved on the power generation input shaft 11, and the second connecting cylinder 351 and the power generation input shaft 11 are fixedly connected by screws. One end of the second connecting shaft 352 is inserted into the end of the second connecting cylinder 351 away from the speed-increasing output shaft 21, and the second connecting shaft 352 and the second connecting cylinder 351 are fixed by screws, and one end of the second connecting shaft 352 is inserted into the end of the second connecting cylinder 351 away from the power generation input shaft 11. The second connecting shaft 352 is inserted into the second connecting cylinder 351, so the distance of the second magnetic mounting disk 321 relative to the speed-increasing output shaft 21 can be adjusted by adjusting the length of the second connecting shaft 352 inserted into the second connecting cylinder 351.

[0038] In some embodiments, when there are multiple active magnets 312 and multiple driven magnets 322, the multiple active magnets 312 are arranged at circumferential intervals along the first magnetic mounting disk 311, and the multiple driven magnets 322 are arranged at circumferential intervals along the second magnetic mounting disk 321. The multiple active magnets 312 and the multiple driven magnets 322 are arranged in one-to-one correspondence to enhance the bearing capacity between the active magnetic component 31 and the driven magnetic component 32 through magnetic transmission.

[0039] The arrangement of the active magnet 312 and the driven magnet 322 can be arbitrarily set according to actual conditions.

When the speed increasing output shaft 21 of the speed increasing box 20 drives the first magnetic mounting disk 311 and the multiple active magnets 312 arranged on the first magnetic mounting disk 311 to rotate, the multiple active magnets 312 drive the multiple driven magnets 322 and the second magnetic mounting disk 321 to rotate, thereby driving the power generation input shaft 11 of the generator 10 to rotate.

When the speed increasing output shaft 21 of the speed increasing box 20 drives the first magnetic mounting disk 311 and the multiple active magnets 312 arranged on the first magnetic mounting disk 311 to rotate, the multiple active magnets 312 drive the multiple driven magnets 322 and the second magnetic mounting disk 321 to rotate, thereby driving the power generation input shaft 11 of the generator 10 to rotate.

[0044] In another embodiment, the corresponding active magnets 312 and driven magnets 322 are arranged at intervals along the radial direction of the first magnetic mounting disk 311.
