Description

Technical Field

[0001] This disclosure pertains to the field of wind power generation technology, and particularly relates to a support structure, generator assembly, and wind turbine generator set. Background Technology

[0002] During operation, wind turbine generators inevitably generate vibrations. A support structure is typically installed between the generator and the frame to reduce the vibrations transmitted from the generator to the frame and lower noise levels. The support structure primarily connects the generator and the frame, bearing the weight of the generator and various operating loads.

[0003] As the capacity of individual wind turbine generators continues to increase, and with the growing need for adaptability to different platforms and regions, the types and interface sizes of wind turbine generators are becoming increasingly diverse. Typically, existing support structures can only accommodate generators with one type of interface, failing to meet the needs of multiple platforms. Summary of the Invention

[0004] The main objective of this disclosure is to provide a support structure, generator assembly, and wind turbine generator set to improve the versatility of the support structure and enable it to adapt to different generators.

[0005] To achieve the above objectives, this disclosure provides the following technical solution:

[0006] One aspect of this disclosure provides a support structure suitable for a generator, the support structure including a support body and a connecting assembly, the support body including an elastomer for absorbing vibration; the connecting assembly including a connecting body and an adapter sleeve, the connecting body being connected to the support body, the connecting body having opposing first and second ends, wherein the first end of the connecting body is used to support the generator, the adapter sleeve is disposed at the second end of the connecting body, the connecting body is provided with a mounting hole, the adapter sleeve is partially detachably disposed within the mounting hole, and the adapter sleeve is provided with a connecting portion configured to receive a connector for connection with the generator.

[0007] This disclosure allows for the detachable connection between the adapter sleeve and the connecting body, with the adapter sleeve and the connector being matched and connected. This facilitates the replacement of the adapter sleeve to accommodate different connectors, thereby enabling the support structure to adapt to different connectors and thus to different generators.

[0008] In one exemplary embodiment of this disclosure, the adapter sleeve includes an adapter sleeve body and an adapter end. The adapter end is disposed at the second end of the connecting body. The adapter sleeve body is fixed to the adapter end and extends from the adapter end into the mounting hole to receive the connector. This embodiment, by disposing the adapter end outside the second end of the connecting body, allows the connecting body to limit the position of the adapter sleeve. When the connector and the adapter sleeve are connected together, the support structure can be connected to the generator base.

[0009] Specifically, the adapter sleeve is provided with a first threaded connection portion for connecting with the connector, so as to improve the connection reliability between the connector and the adapter sleeve.

[0010] In another exemplary embodiment, the adapter sleeve is provided with a second threaded connection portion for connecting with the connecting body, thereby improving the connection reliability between the adapter sleeve and the connecting body.

[0011] Optionally, the adapter end is provided with an end connection portion and is connected to the second end of the connecting body through the end connection portion. This arrangement prevents the adapter end from rotating relative to the connecting body, thereby preventing relative rotation between the adapter sleeve and the connector and improving the connection reliability between the connector and the adapter sleeve.

[0012] Furthermore, the end connection portion includes a first mounting hole, and the second end of the connecting body is provided with a second mounting hole. The adapter end is fixed to the second end of the connecting body through the first mounting hole and the second mounting hole.

[0013] In another exemplary embodiment of this disclosure, the first mounting hole is provided through the top and bottom surfaces of the adapter end; and / or; a plurality of the first mounting holes are provided, and the plurality of the first mounting holes are spaced apart circumferentially along the adapter end; and / or, the first mounting hole is an oblong hole and extends circumferentially along the adapter end, which facilitates the alignment and assembly of the first mounting hole and the second mounting hole, improving the ease of use of the support structure; and / or, the first mounting hole is a smooth hole, which allows the fastener to pass smoothly through the first mounting hole and be threaded onto the second mounting hole, reducing the assembly difficulty of the fastener and thus improving the ease of use of the support structure; and / or, a plurality of the second mounting holes are provided, and the plurality of the second mounting holes are spaced apart circumferentially along the adapter sleeve; and / or, the second mounting hole is a threaded hole.

[0014] In another exemplary embodiment of this disclosure, the connecting assembly further includes a height adjusting body. The first end face of the connecting body is recessed inward to form a height adjustment cavity. The height adjusting body is movably disposed in the height adjustment cavity relative to the connecting body in the height direction of the support structure and can support the generator. By adjusting the extension height of the height adjusting body relative to the height adjustment cavity, the overall height of the connecting assembly can be adjusted so that the connecting assembly can adapt to generators of different heights, thereby improving the versatility of the support structure.

[0015] Optionally, the height adjustment body includes a connecting portion that is threadedly connected to the connecting body. This allows the height adjustment body and the connecting body to be reliably connected, and their position in the height direction of the support structure can be adjusted by turning the height adjustment body, thus improving the ease of use of the height adjustment body to a certain extent. And / or, the height adjustment body is provided with a height adjustment mounting hole configured to allow a connector to pass through to connect the support structure to the generator. The height adjustment body also includes an adjustment interface located at the top of the height adjustment mounting hole. This configuration facilitates turning the height adjustment body with a wrench, thereby improving the ease of use of the height adjustment body.

[0016] Specifically, the minimum diameter of the height adjustment mounting hole is greater than the diameter of the mounting hole of the connecting body.

[0017] In another exemplary embodiment of this disclosure, the height adjustment body is provided with an anti-slip portion, and the connecting assembly further includes at least two limiting members. The at least two limiting members are arranged circumferentially at intervals along the anti-slip portion and are adjustablely connected to the connecting body to abut against the outer peripheral wall of the anti-slip portion. Through the cooperation of the limiting members and the anti-slip portion, when the height adjustment body is used to support a generator, accidental falling of the height adjustment body can be effectively prevented, thereby improving the reliability of the height adjustment body.

[0018] Furthermore, the height adjustment body includes a connecting portion, and the anti-slip portion is disposed above or below the connecting portion along the height direction of the support structure; and / or, the roughness Ra of the outer peripheral wall of the anti-slip portion is ≥25; and / or, the connecting body is provided with a threaded hole that matches the limiting member, and the limiting member is adjustablely connected to the threaded hole.

[0019] In another exemplary embodiment of this disclosure, the connecting assembly further includes a support body and an adapter ring sleeved on the outer periphery of the support body. The support body is disposed above the connecting body and is used to insert into the connection hole of the generator base. The support body can be spaced out within the connection hole of the base, and the adapter ring is tightly fitted between the support body and the connection hole of the base. This embodiment, by tightly fitting the adapter ring between the support body and the connection hole of the base, enables the adapter ring to be reliably connected to the generator, thereby enabling a reliable connection between the support structure and the generator.

[0020] Optionally, the upper part of the support body is provided with an axial limiting part, which is located above the adapter ring. The support structure also includes an axial limiting member, which is detachably connected to the axial limiting part. By providing an axial limiting member above the adapter ring, the accidental detachment of the adapter ring from the support body can be effectively prevented, thereby improving the connection reliability of the support structure.

[0021] Specifically, the axial limiting part includes a retaining ring groove extending circumferentially along the support body, and the axial limiting member includes a retaining ring that can be disposed in the retaining ring groove. In this embodiment, by setting a retaining ring above the adapter ring, the connection is reliable and the structure is simple. While ensuring the reliability of the connection, the cost of the support structure is reduced to a certain extent.

[0022] In another exemplary embodiment of this disclosure, the connecting assembly further includes a support base and an adjusting base. The support base has a mounting hole that is fitted onto the first end of the connecting body and positioned above the support body. The adjusting base is horizontally adjustable above the support base. The supporting body is connected to the adjusting base and protrudes upward relative to the adjusting base. By adjusting the horizontal position between the support base and the adjusting base, the relative position of the generator and the supporting body in the horizontal direction can be adjusted, thereby allowing the horizontal position of the supporting body to be adjusted relative to the generator's base.

[0023] Optionally, the side of the adjusting seat is provided with a flange, which is located on the outer periphery of the support seat. The flange has a flange connecting hole, and the connecting assembly further includes an adjusting member that passes through the flange connecting hole and is adjustablely connected to the support seat. This disclosure achieves horizontal position adjustment between the support seat and the adjusting seat by using a flange on the outer periphery of the support seat and adjusting the adjusting member to achieve the horizontal distance between the flange and the support seat. The structure is simple and easy to operate.

[0024] In another exemplary embodiment of this disclosure, the support body has a through hole, the connecting body includes a connecting sleeve and an end limiting member, the connecting sleeve is provided with a limiting step in the middle of the extending direction, the connecting sleeve passes through the through hole of the support body, the top of the support body is engaged with the limiting step, and the end limiting member is connected to the bottom end of the connecting sleeve and pressed against the bottom of the support body.

[0025] Optionally, at least one of the connecting sleeve and the end limiting member is connected to the adapter sleeve. The adapter sleeve has good versatility; as long as it is connected to one of the connecting sleeve and the end limiting member, the adapter sleeve can be reliably connected to the connecting body.

[0026] In another exemplary embodiment of this disclosure, the support body further includes a first housing and a second housing, the first housing being disposed above the second housing at a distance, and the elastic body being disposed within the accommodating space formed by the first housing and the second housing.

[0027] In another aspect, this disclosure provides a generator assembly including a generator and a support structure as described above, the support structure being connected to a base of the generator.

[0052] Example embodiments will now be described more fully with reference to the accompanying drawings. However, it should not be construed that the embodiments of this disclosure are limited to those described herein. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed descriptions will be omitted.

[0053] In one aspect of this disclosure, a wind turbine generator set is provided, which includes a generator connected to an impeller via a main shaft, for example, but not limited to, the main shaft being connected between the rotor of the generator and the impeller, so as to generate electricity by rotating the rotor of the generator through the rotation of the impeller.

[0054] The wind turbine generator set also includes a frame and a support structure to support the weight of the generator and various working loads. The frame is connected to the tower, and the support structure is located between the frame and the generator. The support structure may include an elastomer 13 to absorb the operating vibration of the generator and reduce noise.

[0055] Reference Figures 1 to 7 This disclosure provides a support structure adapted to the generator of a wind turbine generator set. The support structure includes a support body 100 and a connecting assembly 200. One end of the connecting assembly 200 is connected to the generator base 5, and the other end is connected to the support body 100. This allows the support body 100 to be connected to the generator via the connecting assembly 200. During generator operation, the support body 100 can absorb vibration, thereby reducing noise. (Refer to...) Figure 3 The first end of the connecting component 200 is used to connect to the base 5 of the generator. This first end can be the top of the connecting component 200, but is not limited to this.

[0056] Referring again to the accompanying drawings, in this embodiment, the support body 100 includes a first housing 12, a second housing 14, and an elastic body 13. The first housing 12 and the second housing 14 can be spaced apart and a receiving space for accommodating the elastic body 13 is formed between the first housing 12 and the second housing 14. The elastic body 13 is disposed in the receiving space.

[0057] As an example, the first housing 12, the elastomer 13, and the second housing 14 can be arranged sequentially from top to bottom along the height direction of the support structure, but are not limited thereto.

[0058] When the support structure is connected to the generator, the first housing 12 is spaced above the second housing 14, thereby forming a receiving space between the first housing 12 and the second housing 14 for accommodating the elastomer 13. The elastomer 13 is supported between the first housing 12 and the second housing 14 to absorb generator vibration and reduce noise. As an example, the elastomer 13 can be made of elastic rubber material, but is not limited thereto. To accommodate the elastic deformation of the elastomer 13, a deformation notch 131 is provided in the circumferential direction of the elastomer 13, such as... Figure 7 As shown, but not limited to. As an example, multiple deformation notches 131 are spaced apart along the diameter direction of the elastic body 13. When assembled with the generator, the diameter of the deformation notches 131 can be set perpendicular to the generator's shaft, thereby reducing the coupling resonance of the generator assembly in the direction of the generator's shaft and the direction of the diameter of the deformation notches 131, so as to effectively protect the generator assembly.

[0059] return Figure 2 and Figure 3The first housing 12 provided in this embodiment includes a frustum-shaped housing structure with a cross-section that gradually increases from top to bottom, and the second housing 14 includes a frustum-shaped housing structure with a cross-section that gradually increases from top to bottom. The elastic body 13 is supported in the accommodating space formed by the first housing 12 and the second housing 14. With this arrangement, the support body 100 has better support stability.

[0060] In this embodiment, the first housing 12, the second housing 14, and the elastomer 13 can be formed independently, and the first housing 12, the second housing 14, and the elastomer 13 can be connected together by the connecting component 200. However, this is not a limitation. As needed, the elastomer 13 can also be connected to the first housing 12 and the second housing 14 respectively by adhesive.

[0061] In order to improve the load-bearing capacity of the support body 100, in this embodiment, the first housing 12 and / or the second housing 14 can be rigid components, for example, but not limited to, the first housing 12 and / or the second housing 14 include metal parts. As an example, the first housing 12 and the second housing 14 are made of stainless steel, but not limited thereto.

[0062] In order to reliably connect with the connecting assembly 200, the support body 100 may be provided with a body through hole, the connecting body 201 may be reliably inserted into the body through hole, and the support body 100 may be reliably connected to the base 5 of the generator.

[0063] Specifically, the first housing 12, the second housing 14, and the elastic body 13 are each provided with through holes for the connecting sleeve 11 to pass through, and the through holes on the first housing 12, the second housing 14, and the elastic body 13 are aligned and configured to form the above-mentioned body through holes for the connecting body 201 to pass through.

[0064] This embodiment will be described using the example of connecting the first housing 12, the second housing 14, and the elastomer 13 together through the connecting component 200.

[0065] In this embodiment, the second housing 14 can be connected to the frame, but is not limited thereto. As an example, the second housing 14 is provided with a connection portion for connecting to the frame, such as, but not limited to, a light hole, a threaded hole, or a slotted hole, but is not limited thereto.

[0066] Continue to refer to Figure 2 and Figure 3Specifically, the connection assembly 200 includes a connection body 201. The first end of the connection body 201 can be used to support a generator. For example, but not limited to, the first end of the connection body 201 is disposed below the generator base 5, with the first end and the second end positioned opposite each other. The use of the first end of the connection body 201 to support the generator, as described in this disclosure, includes situations where the first end of the connection body 201 directly contacts and is supported on the bottom surface of the generator base 5. It also includes situations where other components may exist between the first end of the connection body 201 and the generator base 5, in which case the first end of the connection body 201 does not directly contact the generator base 5, but can still be used to support the generator.

[0067] The connecting body 201 includes a connecting sleeve 11 and an end limiting member 15 disposed at the end of the connecting sleeve 11. As an example, the first end of the connecting sleeve 11 is used to support the generator, and the end limiting member 15 is connected to the second end of the connecting sleeve 11.

[0068] Reference Figure 3 The first end of the connecting body 201 can be the top end, and the second end of the connecting body 201 can be the bottom end. In this embodiment, the top end and the bottom end are defined with reference to the orientation in the attached drawings. When the attached drawings are rotated by a predetermined angle, the defined top end and bottom end will be rotated by a predetermined angle accordingly, but this is not a limitation.

[0069] After the connecting sleeve 11 passes through the through hole of the first housing 12, the through hole of the second housing 14, and the through hole of the elastic body 13 from top to bottom, the end limiting member 15 can be connected to the bottom end of the connecting sleeve 11. In this way, the first housing 12, the second housing 14, and the elastic body 13 are connected together by the cooperation of the connecting sleeve 11 and the end limiting member 15.

[0070] As an example, the connecting sleeve 11 and the end limiting member 15 can be detachably connected by threads, or they can be connected by welding or gluing. For ease of replacement, this embodiment uses the threaded connection between the connecting sleeve 11 and the end limiting member 15 as an example for explanation.

[0071] Specifically, the connecting sleeve 11 has a limiting step in the middle of its extension direction. When the connecting sleeve 11 is inserted into the through hole of the support body 100, the top of the support body 100 is engaged at the limiting step, and the first housing 12 is stopped below the limiting step. In an optional embodiment, the bottom end of the connecting sleeve 11 is provided with an external thread, and the end limiting member 15 is provided with a threaded hole that matches the external thread of the connecting sleeve 11. By screwing the end limiting member 15 relative to the connecting sleeve 11 until it is tightened, the support body 100 formed by the first housing 12, the second housing 14, and the elastic body 13 can be reliably connected together.

[0072] Continue to refer to Figure 2 and Figure 3 The connecting body 201 has mounting holes for matching with the connector 3. The connecting assembly 200 also includes an adapter sleeve 16, which is detachably connected to the connecting body 201. By replacing the adapter sleeve 16, different connectors 3 can be adapted to accommodate different generator bases 5, thereby improving the versatility of the support structure.

[0073] Specifically, the adapter sleeve 16 may include an adapter sleeve body 161 and an adapter end 162. The adapter end 162 may be located at the bottom end of the connecting body 201, for example, but not limited to, the adapter end 162 may be located below the bottom end of the connecting body 201. The bottom end of the adapter sleeve body 161 may be fixed to the adapter end 162, and the top end of the adapter sleeve body 161 extends upward and is inserted into the mounting hole of the connecting body 201 and connected to the connecting body 201. The adapter sleeve body 161 can be connected to the connector 3, so that the connector 3 and the adapter sleeve 16 cooperate to connect the support structure to the base 5 of the generator.

[0074] As an example, the adapter sleeve 161 is provided with a first sleeve threaded connection portion for connecting with the connector 3. The adapter sleeve 161 can be threadedly connected to the connector 3 through this first sleeve threaded connection portion, but this is not a limitation. Specifically, the connector 3 is provided with a first external thread, and the first sleeve threaded connection portion includes a first internal thread that matches the first external thread of the connector 3. The connector 3 and the adapter sleeve 161 are connected together by the engagement of the first external thread and the first internal thread.

[0075] Furthermore, the adapter sleeve 161 is also provided with a second sleeve threaded connection portion for connecting with the connecting body 201, so that the adapter sleeve 161 is disposed between the connecting body 201 and the connector 3. As an example, the second sleeve threaded connection portion includes a second external thread provided on the outer periphery of the adapter sleeve 161, and the mounting hole of the connecting body 201 is provided with a second internal thread that matches the second external thread. Through the matching connection of the second internal thread and the second external thread, the adapter sleeve 161 and the connecting body 201 can be threadedly connected, thereby improving the connection reliability between the adapter sleeve 161 and the connecting body 201.

[0076] As an example, the diameter of the mounting hole of the connecting body 201 used to connect with the adapter sleeve 161 is smaller than the minimum diameter of the height adjustment mounting hole. When the outer diameter of the connector 3 is the same as the diameter of the mounting hole of the connecting body 201, the connector 3 can be directly threaded to the connecting body 201. At this time, there is no need to use the adapter sleeve 16, which further improves the versatility of the support structure.

[0077] This embodiment uses the threaded connection between the adapter sleeve 161 and the connecting body 201 as an example for illustration, but it is not limited to this. As needed, the outer periphery of the adapter sleeve 161 can also be set as an optical axis, and it does not need to be connected to the connecting body 201 as a whole. Since the adapter end 162 is located below the bottom end of the connecting body 201, the adapter sleeve 16 can be axially limited. Therefore, by connecting the adapter sleeve 161 and the connector 3 together, the support structure can also be reliably connected to the engine base 5.

[0078] In an optional embodiment, at least one of the connecting sleeve 11 and the end limiting member 15 is provided with a second internal thread, so that the adapter sleeve 161 is threadedly connected to at least one of the connecting sleeve 11 and the end limiting member 15, thereby improving the connection reliability of the adapter sleeve 161.

[0079] Continue to refer to Figure 3 and Figure 4 In order to further improve the reliability of the adapter sleeve 16, the adapter end 162 is provided with an end connection part 163 for connecting to the second end (e.g., the bottom end) of the connecting body 201. The adapter end 162 can be connected to the bottom end of the connecting body 201 through the end connection part.

[0080] Specifically, the end connection 163 includes a first mounting hole that penetrates the top and bottom surfaces of the adapter end 162. The connecting body 201 is provided with a second mounting hole. The adapter end 162 is connected to the bottom end of the connecting body 201 through the first mounting hole and the second mounting hole 151, thereby preventing the adapter sleeve 16 from rotating relative to the connecting body 201 and becoming loose, thus improving the reliability of the support structure.

[0081] As an example, multiple first mounting holes are provided, spaced apart circumferentially along the adapter end 162. Further, the first mounting holes are oblong in shape to facilitate alignment with the second mounting holes, thereby improving the ease of use of the adapter sleeve 16, but this is not a limitation. As an example, the first mounting holes are plain holes, but this is not a limitation.

[0082] As an example, multiple second mounting holes 151 are provided, and the multiple second mounting holes 151 are spaced apart circumferentially along the connecting body 201, but this is not a limitation. In an optional embodiment, the extending direction of the second mounting holes 151 is parallel to the extending direction of the connector 3, but this is not a limitation.

[0083] To improve the versatility of the connecting body, the connecting assembly 200 also includes a height adjustment body 10. The top end of the connecting body 201 is recessed inward to form a height adjustment cavity. The height adjustment body 10 is adjustablely disposed in the height adjustment cavity relative to the connecting body 201 in the height direction of the support structure to adjust the overall height of the connecting assembly 200. For example, but not limited to, when the height adjustment body 10 extends outward from the height adjustment cavity, the overall height of the connecting assembly 200 will increase.

[0084] Under normal circumstances, the top surface of the connecting body 201 can be used as a support surface, typically supporting the base 5 of the generator. In this embodiment, when it is necessary to adjust the overall height of the support structure, the position of the height adjusting body 10 in the height direction of the support structure can be adjusted relative to the connecting body 201. For example, but not limited to, the height adjusting body 10 can be made to extend outward and protrude beyond the top surface of the connecting body 201. In this case, the top surface of the height adjusting body 10 can be used as a support surface to support the base 5 of the generator. This disclosure increases the overall height of the connecting assembly 200 by adjusting the outward protrusion of the height adjusting body 10 relative to the height adjustment cavity of the connecting body 201.

[0085] As an example, the height adjustment body 10 includes a connecting part that can be connected to the connecting body 201, preventing the height adjustment body 10 from moving freely or accidentally detaching from the connecting body 201, thereby improving the reliability of the connecting components.

[0086] In an optional embodiment, the outer peripheral wall of the connecting part is provided with an external thread, and the height adjustment cavity is provided with an internal thread that matches the external thread. Through the threaded connection between the connecting part and the height adjustment cavity, the height adjustment body 10 can protrude outward or retract inward relative to the height adjustment cavity, thereby realizing the adjustable position of the height adjustment body 10 in the height direction.

[0087] Reference Figure 3 To facilitate adjustment of the height adjusting body 10 relative to the connecting body 201, in this embodiment, the height adjusting body 10 is provided with a height adjustment mounting hole. This mounting hole is configured to allow a connector to pass through to connect the support structure to the generator. To facilitate adjustment of the height position of the height adjusting body 10 relative to the connecting assembly 200, an adjustment interface 101 is provided at the top of the height adjustment mounting hole. For example, but not limited to, the adjustment interface 101 is non-circular. An adjustment wrench can be inserted into the height adjustment mounting hole and turned relative to the connecting body 201, thereby causing the height adjusting body 10 to extend outward or retract inward relative to the height adjustment cavity, thus achieving height adjustment of the height adjusting body 10.

[0088] As an example, the adjustment interface 101 can be a regular hexagonal hole, or a plum blossom-shaped hole, or an elliptical hole, or other regular polygonal hole, but is not limited to these.

[0089] Continue to refer to Figure 3 and Figure 4 The height adjustment body 10 is also provided with an anti-slip part, which is disposed above the connecting part along the height direction of the height adjustment body 10. The connecting assembly 200 also includes at least two limiting members 20, which are arranged at intervals along the circumference of the anti-slip part and are adjustablely connected to the connecting body 201 so as to abut against the outer peripheral wall of the anti-slip part, but are not limited thereto. In this embodiment, by abutting against the outer peripheral wall of the anti-slip part with the limiting members 20, the height adjustment body 10 can be prevented from accidentally sliding down, thereby improving the reliability of the height adjustment body 10.

[0090] The at least two limiting members 20 provided in this embodiment can abut against the outer peripheral wall of the anti-slip portion of the height adjusting body 10, thereby preventing the height adjusting body 10 from accidentally falling. Especially when the axial height of the connecting body 201 is insufficient to support the generator base 5, and it is necessary to adjust the outward protrusion height of the height adjusting body 10 relative to the connecting body 201, the top surface of the height adjusting body 10 serves as a support surface. By adjusting the at least two limiting members 20 to abut against the outer peripheral wall of the height adjusting body 10, the accidental fall of the height adjusting body 10 can be effectively prevented, thus improving the load-bearing capacity of the connecting assembly 200.

[0091] As an example, the outer peripheral wall of the anti-slip part is roughened, for example, but not limited to, the surface roughness Ra of the anti-slip part is ≥25, which further improves the reliability of the height adjustment body 10.

[0092] This embodiment uses the example of the anti-slip part being located above the connecting part along the height direction of the support structure for illustration, but it is not limited to this. As needed, the anti-slip part can also be set to be located below the connecting part along the height direction of the support structure.

[0093] As an example, the connecting body 201 is provided with a threaded hole that matches the limiting member 20. The limiting member 20 is adjustablely connected to the threaded hole. By screwing the limiting member 20, the insertion length of the limiting member 20 in the threaded hole can be adjusted, thereby achieving a tight fit against the outer peripheral wall of the anti-slip part of the height adjusting body 10.

[0094] In an optional embodiment, at least two limiting members 20 are arranged at equal angular intervals along the circumference of the connecting body 201, but this is not a limitation. In this embodiment, the connecting component 200 includes two limiting members 20 as an example for illustration, but this is not a limitation. The number of limiting members 20 can also be set to 3 or 4, etc., as needed.

[0095] Referring to the attached figures, as the demand for diversity in generator types and sizes continues to increase, the interfaces (i.e., the connection holes of the base 5) of different generators are also different. In order to improve the versatility of the support structure, the connection assembly 200 also includes a support body 9 and an adapter ring 8 sleeved on the outer periphery of the support body 9.

[0096] Specifically, in order to accommodate the connection holes of different generator bases 5, the support body 9 can be set above the connecting body 201 and can be inserted into the connection hole of the generator base 5. The support body 9 is spaced out in the connection hole of the base 5 and is tightly connected between the support body 9 and the connection hole of the base 5 through the adapter ring 8, so that the upper end of the connecting assembly 200 can be reliably connected to the connection hole of the generator base 5.

[0097] As an example, the support body 9 can be spaced out and fitted into the connection holes of the base 5. It is tightly connected between the support body 9 and the connection holes of the base 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 can be tightly fitted with the connection holes of the base 5, so as to realize the reliable connection between the adapter ring 8, the support body 9 and the base 5, thereby enabling the support structure to be reliably connected in the connection holes of the generator base 5.

[0098] In this embodiment, the connecting holes of the adapter ring 8, the support body 9, and the base 5 can be interference-fitted respectively, so that the connecting component 200 can be reliably connected in the connecting hole of the base 5, and then the supporting structure can be reliably connected to the base 5 of the generator by the connecting piece 3.

[0099] As an example, the adapter ring 8 provided in this embodiment is tightly fitted with the support body 9 and the base 5, including the inner ring of the adapter ring 8 and the support body 9, and the outer ring of the adapter ring 8 and the connecting hole of the base 5, respectively, but this is not a limitation.

[0100] In order to accommodate the connection holes of different generator bases 5, the connection assembly 200 may include multiple adapter rings 8. 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. Multiple adapter rings 8 may have different outer diameters to accommodate the connection holes of different generator bases 5, but are not limited thereto.

[0101] To improve the connection reliability of the adapter ring 8, an axial limiting part is provided on the upper part of the support body 9. The axial limiting part is located above the adapter ring 8. The support structure also includes an axial limiting member 7, which is detachably connected to the axial limiting part. When the axial limiting member 7 is located above the adapter ring 8, the adapter ring 8 is less likely to be pulled upward relative to the support body 9 and thus detach from the support body 9. This improves the connection reliability between the adapter ring 8 and the support body 9, and also improves the reliability of the support structure.

[0102] As an example, the axial limiting part includes a retaining ring groove extending circumferentially along the support body 9, and the axial limiting member 7 includes a retaining ring that can be disposed within the retaining ring groove. In this embodiment, the adapter ring 8 is limited by the retaining ring, which has a simple structure and low cost.

[0103] Continue to refer to Figure 3 and Figure 4 In order to adjust the horizontal position of the support body 100 relative to the generator base 5, the connecting assembly 200 also includes a support base 17 and an adjusting base 18. The support base 17 is provided with a support mounting hole, which is fitted onto the first end of the connecting body 201 and positioned above the support body 100. The support body 100 supports the support base 17 and positions it in the height direction. By setting the connecting body 201 in the support mounting hole, the support base 17 can be reliably connected to the connecting body 201, but this is not a limitation.

[0104] In this embodiment, the top surface of the support base 17 can be in the same plane as the top surface of the connecting body 201, and can be used as a support surface in conjunction with the top surface of the connecting body 201, thereby increasing the area of ​​the support surface of the support structure, but not limited thereto.

[0105] Furthermore, the adjusting seat 18 is horizontally adjustable above the support seat 17, so that the adjusting seat 18 is supported above the connecting body 201. When the height adjusting body 10 is retracted into the height adjustment cavity, the first end of the connecting body 201 directly contacts and supports the bottom surface of the adjusting seat 18, and the top surface of the adjusting seat 18 directly contacts and supports the bottom surface of the generator base 5.

[0106] Specifically, the support body 9 is connected to the adjusting seat 18 and protrudes upward relative to the adjusting seat 18. This arrangement ensures a reliable connection between the support body 9 and the adjusting seat 18. 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, such as... Figure 2 As shown, the vertical direction is the longitudinal direction, and the horizontal direction is the left and right direction. In this embodiment, when the adjusting seat 18 can adjust its position relative to the support assembly in the horizontal direction, and the support body 9 is provided in the connection hole 51 of the base 5, 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 this is not a limitation.

[0107] 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 or fastener connection, both of which are within the protection scope of this disclosure.

[0108] As an example, the side of the adjusting seat 18 is provided with a flange, which is located on the outer periphery of the support seat 17. The flange has a flange connecting hole. The connecting assembly 200 also includes an adjusting member 19, which passes through the flange connecting hole and is adjustablely connected to the support seat 17. By adjusting the length of the adjusting member 19 screwed into the support seat 17, the adjusting seat 18 can be adjusted in the horizontal direction relative to the support seat 17. As an example, this embodiment uses an adjusting bolt as an example for the adjusting member 19, but it is not limited thereto. The adjusting member 19 may also include a telescopic rod or a lead screw assembly. In this case, the adjusting member 19 is connected between the flange and the support seat 17, so that the horizontal relative position between the adjusting seat 18 and the support seat 17 can be adjusted by adjusting the length of the adjusting member 19.

[0109] In another aspect of this disclosure, a generator assembly is provided, the generator assembly including a generator and a support structure as described above, the support structure being connected to the base 5 of the generator.

[0110] Continue to refer to Figure 3 A washer 2 is provided above the base 5. The washer 2 has a through hole for the connector 3 to pass through. When the base 5 of the generator is connected to the support structure, the washer 2 can be fitted onto the connector 3.

[0111] In another aspect, this disclosure provides a wind turbine generator set including a frame and a generator assembly as described above, the generator assembly being connected to the frame.

[0112] This disclosure allows for detachable connection of the adapter sleeve 16 to the connecting body 201. By replacing the adapter sleeve 16, different connecting parts 3 can be adapted to accommodate different generator bases 5, thereby improving the versatility of the support structure.

[0113] In this embodiment, the support structure includes an adapter ring 8 and a support body 9. The adapter ring 8 can be interference-fitted with the connection holes 51 of the support body 9 and the base 5, respectively, so that the support structure can be reliably connected to the connection holes 51 of the base 5. Then, the connector 3 is used to reliably connect the support structure to the base 5 of the generator. By using different adapter rings 8, different connection holes 51 of the generator base 5 can be accommodated, thereby improving the versatility of the support structure.

[0114] Furthermore, by providing an axial limiting part on the support body 9, the adapter ring 8 is prevented from accidentally detaching from the support body 9, thereby improving the connection reliability between the adapter ring 8 and the support body 9.

[0115] In addition, this embodiment includes an adjustment seat 18 in the support structure, which facilitates the adjustment of the position of the support structure relative to the generator, thereby improving the ease of use of the support structure.

[0116] Furthermore, this disclosure improves the versatility of the support structure by using a support body 210 and an adapter sleeve 16 to accommodate different connectors 3 and thus different connection holes 51 of the base 5 of the generator, through the use of different adapter sleeves 16.
