[0042] Example embodiments will now be described more fully with reference to the accompanying drawings. The example embodiments, however, are not to be construed as limiting the scope of the disclosure. Like reference numerals refer to like elements throughout the various drawings. Detailed descriptions of structures are thus omitted herein.

[0043] One aspect of the present disclosure provides a wind turbine generator, which includes a generator connected with an impeller through a main shaft, for example but not limited to, the main shaft is connected between a rotor of the generator and the impeller, so as to drive the rotor of the generator to rotate by the rotation of the impeller, thereby generating electricity.

[0044] The wind turbine generator further includes a frame connected on a tower and a support structure arranged between the frame and the generator, wherein the support structure can include an elastic body 13 for absorbing working vibration of the generator.

[0045] Referring to Figures 1 to 7 The present disclosure provides a support structure adapted to a generator of a wind turbine generator, which includes a support assembly including an elastic body 13 for absorbing vibration, a support body 9 connected to the support assembly and spacedly sleeved in a connecting hole 51 of a base 5 of the generator, and an adapter ring 8 sleeved between an outer circumferential side of the support body 9 and the connecting hole 51, and the adapter ring 8 is tightly fitted with the support body 9 and the connecting hole 51 of the base 5, respectively.

[0046] The present disclosure includes the support body 9 and the adapter ring 8 in the support structure to be tightly fitted and connected into the connecting hole 51 of the base 5, and different adapter rings 8 can be used to adapt to different connecting holes 51 of the base 5 of different generators, thereby improving the versatility of the support structure.

[0047] Specifically, in order to adapt to the connecting holes 51 of the bases 5 of different generators, the support body 9 can be connected to the support assembly and can be inserted into the connecting holes 51 of the bases 5 of the generators. For example, but not limited to, the support body 9 can be sleeved in the connecting holes 51 of the bases 5, and then be tightly connected between the support body 9 and the connecting holes 51 of the bases 5 through the adapter ring 8. That is, the inner ring of the adapter ring 8 can be tightly fitted with the support body 9, and the outer ring of the adapter ring 8 can be tightly fitted with the connecting holes 51 of the bases 5, so as to reliably connect the adapter ring 8 with the support body 9 and the bases 5, thereby enabling the support structure to be reliably connected in the connecting holes 51 of the bases 5 of the generators.

[0048] As an example, the tight fitting of the adapter ring 8 with the support body 9 and the base 5 respectively in the embodiment includes interference fitting of the inner ring of the adapter ring 8 with the support body 9 and the outer ring of the adapter ring 8 with the connecting holes 51 of the base 5, but is not limited thereto.

[0049] In order to adapt to the connecting holes 51 of the bases 5 of different generators, the support structure can include a plurality of adapter rings 8, and the plurality of adapter rings 8 can have different outer diameters to adapt to the connecting holes 51 of the bases 5 of different generators. The inner diameter of the adapter ring 8 is the same as the outer diameter of the support body 9, and the adapter ring 8 can be interference fitted with the support body 9, but is not limited thereto.

[0050] In order to further improve the connection reliability of the adapter ring 8, the upper portion of the support body 9 is provided with an axial limiting portion which is located above the adapter ring 8. The support structure further includes an axial limiting piece 7 which is detachably connected to the axial limiting portion. When the axial limiting piece 7 is arranged above the adapter ring 8, the adapter ring 8 is not easy to be pulled out upward relative to the support body 9 to cause disengagement from the support body 9, thereby improving the connection reliability between the adapter ring 8 and the support body 9, and improving the use reliability of the support structure.

[0051] As an example, the axial limiting portion can include a circlip groove extending along the circumference of the support body 9, and the axial limiting piece 7 includes a circlip which can be arranged in the circlip groove. In the embodiment, the adapter ring 8 is limited by the circlip, which has a simple structure and low cost.

[0052] Continuing to refer to Figures 2 to 4 In the embodiment, the support structure further includes a aligning assembly which is arranged in the support assembly and is configured to adjust the relative position between the support body 9 and the support assembly. The position of the support assembly relative to the support body 9 can be adjusted in the horizontal direction, so that the support assembly can be adjusted in the horizontal position relative to the generator, thereby improving the use convenience of the support structure.

[0053] As an example, the support structure further comprises an adjusting seat 18, which is arranged above the support assembly in a horizontally adjustable manner, and the support body 9 is connected to the adjusting seat 18 and protrudes upward relative to the adjusting seat 18. In this way, the support body 9 and the adjusting seat 18 are reliably connected together, and when the adjusting seat 18 moves relative to the support assembly in the horizontal plane, it can drive the relative movement of the support body 9 and the support assembly, as shown in Figure 2 The up-down direction is the longitudinal direction, and the left-right direction is the horizontal direction. In this embodiment, when the adjusting seat 18 adjusts the position in the horizontal direction relative to the support assembly, the support body 9 is arranged in the connecting hole of the base 5, so that the position of the support assembly relative to the support body 9 can be adjusted in the horizontal direction, so that the support assembly can be adjusted in the horizontal position relative to the generator, but not limited thereto.

[0054] Specifically, the connection between the support body 9 and the adjusting seat 18 can be a tight connection formed by interference fit, or a fixed connection formed by welding process or fastener connection, all of which are within the protection scope of the present disclosure.

[0055] As an example, the side of the adjusting seat 18 can be provided with a flange, which is arranged on the outer circumferential side of the support assembly, and the flange is provided with a flange connecting hole. The adjusting assembly further comprises an adjusting member 19, which is adjustably connected to the radial outer side of the support seat 17.

[0056] As shown in Figure 2 The adjusting member 19 is arranged in the flange connecting hole and is adjustably connected to the support assembly, so that by adjusting the length of the adjusting member 19 screwed into the support assembly, the adjusting seat 18 can be adjusted in the horizontal direction relative to the support assembly to adjust the installation position of the support structure on the base 5 of the generator.

[0057] In this embodiment, the adjusting member 19 includes an adjusting bolt as an example, but not limited thereto. According to the needs, the adjusting member can also include a telescopic rod or a lead screw assembly, etc. Length adjustable component, so as to realize the position adjustment between the support body 9 and the support assembly by adjusting the length of the length adjustable component, but not limited thereto. In this embodiment, the extension direction of the adjusting member 19 is parallel to the horizontal plane, but not limited thereto.

[0058] In an optional embodiment, the adjusting seat 18 and the flange can be formed in an integral structure, or the adjusting seat 18 and the flange can be formed separately and connected together by welding process or fastener connection. As an example, the adjusting seat 18 can be a metal part, for example but not limited to, the adjusting seat 18 can be a stainless steel part.

[0059] Continuing to refer to Figure 2In the embodiment, the support assembly further comprises a support base 17 arranged below the adjusting base 18 and supporting the support body 9, so as to stably support the adjusting base 18 by the support base 17. The flange is arranged on the outer circumferential side of the support base 17. The adjusting member 19 is adjustably connected to the support base 17, for example but not limited to, by adjusting the length of the adjusting member 19 inserted into the support base 17, the relative position adjustment of the adjusting base 18 and the support base 17 in the horizontal direction can be driven, but not limited thereto.

[0060] With reference to the accompanying drawings, in the embodiment, the support assembly further comprises a support body 100, which is mainly used to absorb the vibration of the generator. The elastic body 13 is part of the support body 100.

[0061] In order to improve the structural strength of the support body 100, the support body 100 further comprises a first shell 12 and a second shell 14 with predetermined structural strength. The first shell 12 and the second shell 14 can be arranged in a spaced manner and form an accommodating space for accommodating the elastic body 13 between the first shell 12 and the second shell 14. The elastic body 13 is arranged in the accommodating space.

[0062] In the case where the support structure is connected to the generator, the first shell 12 is arranged in a spaced manner above the second shell 14, and the elastic body 13 is supported between the first shell 12 and the second shell 14 to be able to absorb the vibration of the generator. As an example, the elastic body 13 can be made of elastic rubber material, but not limited thereto.

[0063] In order to adapt to the elastic deformation of the elastic body 13, the elastic body 13 is provided with a deformation gap 131 in the circumferential direction, as shown in Figure 7 As an example, a plurality of deformation gaps 131 are arranged in a spaced manner along the diameter direction of the elastic body 13. When the generator is assembled, the diameter direction of the deformation gap 131 can be arranged perpendicular to the rotating shaft of the generator, so as to reduce the coupling resonance of the generator assembly in the direction of the rotating shaft of the generator and the direction of the diameter of the deformation gap 131, thereby effectively protecting the generator assembly.

[0064] Returning to Figure 2 and Figure 3 In the embodiment, the first shell 12 comprises a frustoconical shell structure with gradually increasing cross section from top to bottom. The second shell 14 comprises a frustoconical shell structure with gradually increasing cross section from top to bottom. The elastic body 13 is supported in the accommodating space formed by the first shell 12 and the second shell 14. In this way, the support body 100 has better support stability.

[0065] In the embodiment, the first shell 12, the second shell 14 and the elastic body 13 can be independently formed, and the first shell 12, the second shell 14 and the elastic body 13 are connected together through the connecting assembly 200 (as described below), but the application is not limited thereto. According to the needs, the elastic body 13 can also be connected with the first shell 12 and the second shell 14 respectively by means of adhesion, but the application is not limited thereto.

[0066] In order to improve the carrying capacity of the support body 100, in the embodiment, the first shell 12 and the second shell 14 can be rigid members, for example but not limited to, the first shell 12 and / or the second shell 14 include metal parts, but the application is not limited thereto.

[0067] In the embodiment, the support assembly can further include a connecting assembly 200, and the support body 100 can be connected to the base 5 of the generator through the connecting assembly 200, thereby improving the connection reliability of the support body 100.

[0068] In order to be able to reliably connect with the connecting assembly 200, the support body 100 can be provided with a body through hole, and the connecting assembly 200 can be reliably threaded in the body through hole and can reliably connect the support body 100 to the base 5 of the generator.

[0069] Specifically, the first shell 12, the second shell 14 and the elastic body 13 are respectively provided with through holes for the connecting sleeve body 11 to pass through, and the through holes on the first shell 12, the second shell 14 and the elastic body 13 are arranged in position to form the above-mentioned body through hole for the connecting assembly 200 to pass through.

[0070] The embodiment will be described by taking the example of connecting the first shell 12, the second shell 14 and the elastic body 13 together through the connecting assembly 200.

[0071] Specifically, one end of the connecting assembly 200 is used to be connected to the base 5 of the generator, and the other end is used to be connected to the support body 100, so that the support body 100 can be connected to the generator through the connecting assembly 200, and during the operation of the generator, the vibration is absorbed by the support body 100 to reduce the noise.

[0072] Referring to Figure 2 and Figure 3 , the first end of the connecting assembly 200 is indirectly connected to the base 5 of the generator, specifically, the first end of the connecting assembly 200 is supported below the adjusting seat 18 to provide reliable support for the adjusting seat 18, for example but not limited to, the first end can be the top end of the connecting assembly 200, but the application is not limited thereto.

[0073] With reference to the accompanying drawings, in the embodiment, the connecting assembly 200 is arranged through the support base 17 and the support body 100, and the support base 17 is arranged above the support body 100. The support base 17 and the support body 100 are arranged in a stacked manner in the height direction, and the support base 17 and the support body 100 are connected together by the connecting assembly 200, but are not limited thereto.

[0074] Specifically, the support base 17 is provided with a support seat mounting hole, which is sleeved with the first end of the connecting assembly 200 and arranged above the support body 100. The support base 17 is supported and positioned in the height direction by the support body 100. The support base 17 can be reliably connected to the connecting assembly 200 by being arranged in the support seat mounting hole, but is not limited thereto.

[0075] In the embodiment, the top surface of the connecting assembly 200 can be used as a support surface, and the top surface of the support base 17 can be in the same plane as the top surface of the connecting assembly 200 and can be used as a support surface together with the top surface of the connecting assembly 200, thereby increasing the area of the support surface of the support structure, but is not limited thereto.

[0076] With reference to the accompanying drawings, Figure 2 and Figure 3 The support assembly further includes a height adjusting body 10. The first end surface of the connecting assembly 200 is inwardly recessed to form an adjusting cavity. The height adjusting body 10 is adjustably arranged in the adjusting cavity in the height direction relative to the connecting assembly 200 and supports the support body 9, so as to adjust the overall height of the support assembly. For example, but not limited to, when the height adjusting body 10 extends outward from the adjusting cavity, the overall height of the support assembly will increase. By adjusting the position of the height adjusting body 10 in the height direction relative to the adjusting cavity, the use versatility of the support structure is improved.

[0077] Generally, the height adjusting body 10 can be retracted into the adjusting cavity. At this time, the top surface of the connecting assembly 200 is used as a support surface and can be generally supported below the base 5 of the generator. For example, but not limited to, the top surface of the connecting assembly 200 can be supported on the bottom surface of the adjusting seat 18. In the embodiment, when the height of the support assembly needs to be increased, the height adjusting body 10 is adjusted to extend outward from the adjusting cavity. At this time, the top surface of the height adjusting body 10 can be used as a support surface to be supported below the base 5 of the generator. For example, but not limited to, it can be supported on the bottom surface of the adjusting seat 18. In this way, the overall height of the support structure can be adjusted to adapt to the height requirements of different generators.

[0078] As an example, the height adjusting body 10 includes a connecting portion which can be connected with the connecting assembly 200 to avoid the height adjusting body 10 from being randomly moved or accidentally separated relative to the connecting assembly 200, thereby improving the use reliability of the connecting assembly.

[0079] Optionally, the outer circumferential wall of the connecting part is provided with external threads, the height adjusting cavity is provided with internal threads matched with the external threads, and the height adjusting body 10 can protrude outward or retract inward relative to the height adjusting cavity through threaded connection of the connecting part and the height adjusting cavity, so that the height adjusting body 10 is adjustable in the height direction.

[0080] With reference to Figure 3 In this embodiment, the height adjusting body 10 is provided with a height adjusting mounting hole configured to allow the connecting member to pass through to connect the support structure to the generator. In order to facilitate adjustment of the height position of the height adjusting body 10 relative to the connecting assembly 200, the top of the height adjusting mounting hole is provided with an adjustment interface 101, for example but not limited to, a non-circular hole. An adjustment wrench can be inserted into the height adjusting mounting hole and screwed relative to the connecting assembly 200, so that the height adjusting body 10 can protrude outward or retract inward relative to the height adjusting cavity, thereby achieving adjustment of the height adjusting body 10 in the height direction.

[0081] For example, the adjustment interface 101 can be a regular hexagonal hole, or a keyhole, or an oval hole, or other regular polygonal hole, which avoids rotation of the adjustment wrench relative to the adjustment interface 101 when driving the height adjusting body 10, thereby improving the use reliability of the height adjusting body 10, but is not limited thereto.

[0082] With reference to Figure 3 and Figure 4 The height adjusting body 10 is also provided with an anti-skid part arranged above the connecting part in the height direction of the height adjusting body 10, and the support assembly further comprises at least two limiters 20 arranged in a circumferential direction of the anti-skid part and adjustably connected to the connecting assembly 200 to abut against the outer circumferential wall of the anti-skid part, but not limited thereto. In this embodiment, the limiters 20 and the outer circumferential wall of the anti-skid part abut against each other, thereby avoiding accidental sliding down of the height adjusting body 10, and improving the use reliability of the height adjusting body 10.

[0083] The at least two limiters 20 provided in this embodiment can abut against the outer circumferential wall of the anti-skid part of the height adjusting body 10, thereby avoiding accidental falling of the height adjusting body 10. Especially in the case where the axial height of the connecting assembly 200 is not sufficient to support the base 5 of the generator, and the height of the height adjusting body 10 needs to be adjusted to protrude outward relative to the connecting assembly 200, at this time the top surface of the height adjusting body 10 is used as a support surface, and the outer circumferential wall of the height adjusting body 10 is abutted by the at least two limiters 20, which can effectively prevent the height adjusting body 10 from accidentally falling, thereby improving the carrying capacity of the support assembly.

[0084] As an example, the outer circumferential wall of the anti-skid part is roughened, for example but not limited to, the surface roughness Ra of the anti-skid part is greater than or equal to 25, which further improves the use reliability of the height adjusting body 10.

[0085] The present embodiment is described by way of example with the anti-skid part arranged above the connecting part along the height direction of the support structure, but is not limited thereto. The anti-skid part can also be arranged below the connecting part along the height direction of the support structure as needed.

[0086] As an example, the connecting assembly 200 is provided with a threaded hole matched with the limiting piece 20, and the limiting piece 20 is adjustably connected in the threaded hole. By screwing the limiting piece 20, the extending length of the limiting piece 20 in the threaded hole can be adjusted, so as to realize the abutting against the outer circumferential wall of the anti-skid part of the height adjusting body 10.

[0087] Optionally, at least two limiting pieces 20 are arranged equiangularly along the circumference of the connecting assembly 200, but are not limited thereto. In the present embodiment, the connecting assembly 200 is described by way of example with two limiting pieces 20, but is not limited thereto. The number of limiting pieces 20 can also be set to three or four as needed.

[0088] Continuing to refer to Figure 2 and Figure 3 , the connecting assembly 200 includes a connecting body 201, the connecting body 201 includes a connecting sleeve 11 and an end limiting piece 15 arranged at the end of the connecting sleeve 11. The first end of the connecting body 201 can be used to support the generator, for example but not limited to, the first end of the connecting body 201 is arranged below the base 5 of the generator. In fact, the first end face of the connecting body 201 is supported on the bottom face of the adjusting seat 18.

[0089] Continuing to refer to Figure 2 and Figure 3 , the first end of the connecting body 201 can be a top end, and the second end of the connecting body 201 can be a bottom end. The top end and the bottom end defined in the present embodiment are defined with reference to the orientation in the drawings. In the case of rotating the drawings by a predetermined angle, the defined top end and bottom end will be rotated by a predetermined angle accordingly, but are not limited thereto.

[0090] Specifically, the connecting sleeve 11 is sequentially passed through the through hole of the first shell 12, the through hole of the second shell 14, and the through hole of the elastic body 13 from top to bottom, and then the end limiting piece 15 is connected to the bottom end of the connecting sleeve 11. In this way, the first shell 12, the second shell 14, and the elastic body 13 are connected together through the cooperation of the connecting sleeve 11 and the end limiting piece 15.

[0091] As an example, the connection sleeve body 11 and the end limiting member 15 can be detachably connected through threads, or can be connected together by welding or gluing. In order to facilitate replacement, the embodiment is described by taking the threaded connection between the connection sleeve body 11 and the end limiting member 15 as an example.

[0092] Specifically, the connection sleeve body 11 is provided with a limiting step in the middle of the extension direction. In the case where the connection sleeve body 11 penetrates the body through hole of the support body 100, the top of the support body 100 is clamped at the limiting step, and at this time the first shell 12 is stopped from being limited below the limiting step. Optionally, the bottom end of the connection sleeve body 11 is provided with external threads, and the end limiting member 15 is provided with a threaded hole matched with the external threads of the connection sleeve body 11. By screwing the end limiting member 15 relative to the connection sleeve body 11 to be tightened, the support body 100 formed by the first shell 12, the second shell 14 and the elastic body 13 can be reliably connected together.

[0093] As an example, the support seat 17 is sleeved on the top of the connection sleeve body 11, but it is not limited thereto.

[0094] Continuing to refer to Figure 2 and Figure 3 The connection body 201 has a mounting hole for matching with the connecting piece 3, and the connection assembly 200 further comprises an adapter sleeve 16 which is detachably connected to the connection body 201. By replacing the adapter sleeve 16, different connecting pieces 3 can be adapted, so that different bases 5 of the generator can be adapted, and the versatility of the support structure is improved.

[0095] Specifically, the adapter sleeve 16 comprises an adapter sleeve body 161 and an adapter end 162.
