Description

Technical Field

[0001] This utility model relates to the field of wind power generation, and in particular to a stator support structure component, a stator support structure, and a stator. Background Technology

[0002] The stator of a wind turbine includes a stator core and a stator support structure. The stator core is formed by stacking multiple laminations along the axial direction of the stator. The stator support structure is located on the outer or inner periphery of the stator core and is used to fix and support the stator core to prevent collision between the stator and the rotor.

[0003] The stator support structure includes two axial end plates and support ribs. The support ribs extend along the axial direction of the stator, and their two ends are welded to the corresponding axial end plates. Because the stator structure used in wind turbines is relatively large, the stator support structure needs sufficient strength to ensure its stability.

[0004] Increasing the strength of the support ribs is one way to improve the overall strength of the stator support structure. Current technology generally enhances the strength of individual support ribs by increasing the number of bends. However, since the bending angle must be controlled at each bend, more bends result in more labor time and higher processing costs. Furthermore, with a fixed support rib width, more bends mean that the size of individual bend areas within the support rib must be designed to be smaller, leading to less welding space between some bend areas and the axial end plate, increasing welding difficulty and costs. Utility Model Content

[0005] The present invention aims to overcome the existing defects and provide a stator support structure component, stator support structure, and stator that are easy to weld and have a stable structure.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A stator support structure component, the stator support structure component comprising a support rib and a first reinforcing plate;

[0008] The support rib extends along the axial direction of the stator. The support rib includes a connecting plate and two side plates. The connecting plate is used to connect with the stator core. The two side plates are respectively connected to the two ends of the connecting plate in the circumferential direction of the stator and are located on the same side of the connecting plate in the radial direction of the stator. The connecting plate and the two side plates form a groove for accommodating the first reinforcing plate. The first reinforcing plate is connected to the support rib.

[0009] In this design, the first reinforcing plate enhances the radial and tangential rigidity of the support ribs, thereby ensuring the overall strength of the stator support structure while minimizing the number of rib bends. This approach achieves the feasibility of reducing the number of bends for individual support ribs, reducing overall bending difficulty and manufacturing costs, while maintaining stator structural stability. With the support ribs having the same circumferential width along the stator, reducing the number of bends allows for a larger width of the connecting plate, enabling a larger distance between the two side plates. This provides more welding space for welding to the axial end plates of the stator support structure, reducing welding difficulty and costs.

[0010] Preferably, the included angle between the connecting plate and the side plate is defined as α, where 90°≤α<180°.

[0011] In this scheme, the above-mentioned configuration can firstly ensure the structural strength of the support ribs and resist the deformation caused by electromagnetic force during the operation of the wind turbine; secondly, ensure that there is sufficient space between two adjacent support ribs in the circumferential direction of the stator to achieve ventilation and cooling of the stator core; and thirdly, prevent the distance between the two side plates in the circumferential direction of the stator from being too small, which facilitates the welding of the support ribs and the axial end plates.

[0012] Preferably, the three sides of the first reinforcing plate are connected to the connecting plate and the two side plates, respectively.

[0013] In this scheme, the above arrangement enables the connecting plate of the supporting rib and the two side plates to be reinforced by the first reinforcing plate.

[0014] Preferably, the end of the first reinforcing plate facing outward from the groove in the radial direction of the stator is recessed inward from the radial direction of the stator toward the interior of the first reinforcing plate.

[0015] In this design, the above-mentioned features prevent stress concentration at the weld between the first reinforcing plate and the support rib, improve the welding effect, and ensure the overall structural strength of the stator support structure components.

[0016] Preferably, there are multiple support ribs, and the multiple support ribs are arranged at intervals along the circumference of the stator;

[0017] The stator support structure component further includes a second reinforcing plate, which is connected to the side plates of two adjacent support ribs at both ends of the stator in the circumferential direction.

[0018] In this design, the second reinforcing plate can further improve the radial and tangential rigidity of the support ribs, thereby further enhancing the overall strength of the stator support structure components.

[0019] Preferably, the stator support structure component further includes two fixing plates spaced apart along the circumference of the stator, and a plurality of the support ribs are disposed between the two fixing plates in the circumference of the stator;

[0020] The stator support structure component further includes a third reinforcing plate, which is disposed between the fixed plate and the support rib adjacent to the fixed plate. The three reinforcing plates are connected to the side plates of the fixed plate and the support rib respectively at both ends of the stator in the circumferential direction.

[0021] In this design, the third reinforcing plate can further improve the radial and tangential rigidity of the support ribs, thereby further enhancing the overall strength of the stator support structure components.

[0022] Preferably, for the support ribs adjacent to the fixing plate in the circumferential direction of the stator, the side plate of the support ribs on the side of the stator closer to the fixing plate in the circumferential direction of the stator is defined as the first side plate, and the side plate of the support ribs on the side of the stator away from the fixing plate in the circumferential direction of the stator is defined as the second side plate, and the included angle α1 between the first side plate and the connecting plate is less than or equal to the included angle α2 between the second side plate and the connecting plate.

[0023] In this solution, the above-mentioned arrangement is used to ensure that there is sufficient gap between the support rib and the fixing plate, so as to reserve enough welding space for the third reinforcing plate, thereby reducing welding difficulty and welding cost.

[0024] Preferably, at least one end of the second reinforcing plate in the radial direction of the stator is recessed toward the interior of the second reinforcing plate in the radial direction of the stator;

[0025] And / or, at least one end of the third reinforcing plate in the radial direction of the stator is recessed toward the interior of the third reinforcing plate in the radial direction of the stator.

[0026] In this solution, the above-mentioned design prevents stress concentration at the weld joints of the second reinforcing plate and the support rib, the third reinforcing plate and the support rib, and the third reinforcing plate and the fixing plate, thereby improving the welding effect and ensuring the overall structural strength of the stator support structure components.

[0027] Preferably, the first reinforcing plate, the second reinforcing plate, and the third reinforcing plate are located at the same position of the stator support structure component in the axial direction of the stator.

[0028] In this design, the first, second, and third reinforcing plates are horizontally arranged in the axial direction of the stator. As a result, under the action of the tangential force generated by the wind turbine torque on the stator, the tangential force can be effectively transmitted between two adjacent reinforcing plates in the circumferential direction of the stator, resisting the compressive force exerted by the reinforcing plates on the support ribs, preventing deformation of the support ribs, and enhancing the rigidity of the stator support structure components.

[0029] A stator support structure includes a plurality of stator support structure components as described above, wherein the plurality of stator support structure components are arranged sequentially along the circumference of the stator.

[0030] In this solution, the stator support structure is divided into multiple stator support structure components, which reduces the overall transportation and assembly difficulty of the stator support structure and saves time.

[0031] Preferably, the stator support structure further includes a connector, and the fixing plate of the stator support structure component is provided with a connecting hole, which extends along the thickness direction of the fixing plate;

[0032] For two stator support structure components that are adjacent in the circumferential direction of the stator, the connector passes through the connection hole on the fixing plate on which the two stator support structure components face each other.

[0033] In this scheme, multiple stator support structure components are connected into a whole by connectors, which improves the overall rigidity of the stator support structure and enhances the structural stability of the stator.

[0034] A stator includes a stator core and a stator support structure as described above. The stator core is sleeved on the outer periphery of the stator support structure, or the stator support structure is sleeved on the outer periphery of the stator core. The stator core is connected to the connecting plate, and the opening of the groove faces the side away from the stator core in the radial direction of the stator.

[0035] In this design, the connecting plate of the stator support structure is connected to the stator core to fix and support the stator core and prevent collisions between the stator and the rotor.

[0036] The positive and progressive effects of this utility model are as follows: The first reinforcing plate can improve the radial and tangential rigidity of the support ribs, thereby ensuring the overall strength of the stator support structure components even with fewer bends in the support ribs. This achieves the feasibility of reducing the number of bends in individual support ribs while ensuring the stability of the stator structure, reducing the overall bending difficulty and manufacturing cost of the support ribs. With the support ribs having the same width along the circumference of the stator, the reduced number of bends in the support ribs allows for a larger width of the connecting plate, i.e., a larger distance between the two side plates. This provides more welding space for welding to the axial end plates of the stator support structure, reducing welding difficulty and cost. Attached Figure Description

[0062] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0063] like Figure 1 As shown, this embodiment discloses a stator, which is particularly suitable for wind turbine generators. The stator in this embodiment is an inner stator, that is, the rotor is sleeved on the outer periphery of the stator.

[0064] like Figure 1 As shown, the stator includes a stator core 1 and a stator support structure. The stator core 1 is formed by stacking multiple laminations along the axial direction of the stator. The stator core 1 is sleeved on the outer periphery of the stator support structure. The stator support structure is connected to the stator core 1 and is used to fix and support the stator core 1.

[0065] In this embodiment, the stator support structure includes multiple stator support structure components 2, which are arranged sequentially along the circumference of the stator and connected to form a ring-shaped stator support structure. The smaller individual stator support structure components 2 are easier to transport than the larger overall stator support structure, reducing the overall transportation and assembly difficulty, thus saving time and improving efficiency. The specific number of stator support structure components 2 in a single stator support structure can be designed according to actual conditions.

[0066] like Figures 2-4 As shown, the stator support structure component 2 includes an axial end plate 3, a fixing plate 4, a support rib 5, a first reinforcing plate 61, a second reinforcing plate 62, and a third reinforcing plate 63.

[0067] like Figures 2-4As shown, there are two axial end plates 3 and two fixing plates 4. The two axial end plates 3 are spaced apart along the axial direction of the stator, and the two fixing plates 4 are spaced apart along the circumferential direction of the stator. The two ends of the two fixing plates 4 in the axial direction of the stator are respectively connected to the axial end plates 3 on the corresponding sides. There are multiple support ribs 5. The multiple support ribs 5 are spaced apart along the circumferential direction of the stator and all extend along the axial direction of the stator. The gap between two adjacent support ribs 5 is used to realize ventilation and cooling of the stator core 1. The multiple support ribs 5 are arranged between the two fixing plates 4 in the circumferential direction of the stator, and the two ends of the multiple support ribs 5 in the axial direction of the stator are respectively connected to the axial end plates 3 on the corresponding sides.

[0068] In this embodiment, the axial end plate 3 and the fixed plate 4, as well as the axial end plate 3 and the support rib 5, are fixedly connected by welding to improve the structural strength of the stator support structure component 2.

[0069] like Figure 3 As shown, the stator support structure also includes connectors (not shown in the figure). Each of the two fixing plates 4 of a single stator support structure component 2 has a connecting hole 41. The connecting hole 41 extends along the thickness direction of the fixing plate 4 and penetrates the corresponding side of the fixing plate 4. For two stator support structure components 2 adjacent in the circumferential direction of the stator, the fixing plates 4 of the two stator support structure components 2 facing each other abut against each other, and the connecting holes 41 on the two fixing plates 4 are correspondingly arranged. The connector passes through the connecting holes 41 on the fixing plates 4 of the two stator support structure components 2 facing each other, thereby realizing the connection between two stator support structure components 2 adjacent in the circumferential direction of the stator. This method connects multiple stator support structure components 2 into a whole, improving the overall rigidity of the stator support structure and enhancing the structural stability of the stator. The connector can be a detachable connection structure such as a bolt to facilitate stator maintenance.

[0070] like Figures 2-5 As shown, the support rib 5 includes a connecting plate 51 and two side plates 52.

[0071] like Figures 1-3 As shown, the connecting plate 51 is connected to the stator core 1 and is used to fix the stator core 1. Specifically, the connecting plate 51 has a plurality of mounting holes 511 spaced apart along the axial direction of the stator. The mounting holes 511 pass through both ends in the thickness direction of the connecting plate 51. The mounting member 512 passes through the mounting holes 511 from the radially inner side of the stator support structure component 2 and connects to the stator core 1 located on the radially outer side of the stator support structure component 2. The mounting member 512 can be a detachable connection structure such as a bolt, which facilitates the maintenance of the stator.

[0072] like Figures 3-5As shown, the two side plates 52 are respectively connected to the two ends of the connecting plate 51 in the circumferential direction of the stator, and both are located on the side of the connecting plate 51 in the radial direction of the stator away from the stator core 1. The connecting plate 51 and the two side plates 52 form a groove 523. The opening of the groove 523 faces the side away from the stator core 1 in the radial direction of the stator (in this embodiment, it faces the radial inner side of the stator).

[0073] In this embodiment, as Figure 5 As shown, the cross-section of the support rib 5 perpendicular to the stator axis is C-shaped, meaning the support rib 5 only requires two bends, reducing the number of bends and the overall bending difficulty, thus lowering the manufacturing cost of the support rib 5. Furthermore, since there are only two bends, with the support rib 5 having the same width along the stator circumference, the width of the connecting plate 51 along the stator circumference can be designed to be larger, meaning the distance between the two side plates 52 can be designed to be larger. This provides more welding space for welding to the axial end plate 3 of the stator support structure, reducing welding difficulty and cost.

[0074] like Figure 3 and Figure 4 As shown, the first reinforcing plate 61 is disposed within the groove 523 and is connected to the support rib 5. The mounting hole 511 is positioned to avoid the first reinforcing plate 61. The first reinforcing plate 61 can improve the radial and tangential rigidity of the support rib 5, thereby ensuring the overall strength of the stator support structure component 2 even with a smaller number of bends in the support rib 5. This avoids a decrease in the strength of the stator support structure component 2 due to a reduction in the number of bends in the support rib 5, and achieves the feasibility of reducing the number of bends in a single support rib 5 while ensuring the stability of the stator structure.

[0075] In this embodiment, as Figure 4 As shown, the three sides of the first reinforcing plate 61 are connected to the connecting plate 51 and the two side plates 52, respectively. The outer edge shape of the first reinforcing plate 61 is adapted to the shape of the groove 523. The connecting plate 51 and the two side plates 52 of the support rib 5 are directly connected to the first reinforcing plate 61, so that the connecting plate 51 and the two side plates 52 of the support rib 5 can all be reinforced by the first reinforcing plate 61, ensuring the overall strength of the stator support structure component 2.

[0076] Furthermore, such as Figure 4 As shown, the first reinforcing plate 61 is recessed in the radial direction of the stator towards the outside of the groove 523 at one end, in order to prevent stress concentration at the weld between the first reinforcing plate 61 and the support rib 5, improve the welding effect, and ensure the overall structural strength of the stator support structure component 2.

[0077] In other alternative embodiments, the first reinforcing plate 61 may also be connected only to the two side plates 52. In this state, the end of the first reinforcing plate 61 facing the inside of the groove 523 in the radial direction of the stator may also be recessed in the radial direction of the stator toward the inside of the first reinforcing plate 61 to prevent stress concentration at the weld between the first reinforcing plate 61 and the support rib 5.

[0078] like Figures 2-4 As shown, the second reinforcing plate 62 is disposed between two adjacent support ribs 5, and the two ends of the second reinforcing plate 62 in the circumferential direction of the stator are respectively connected to the side plates 52 of the two adjacent support ribs 5 facing each other. The second reinforcing plate 62 can further improve the radial and tangential rigidity of the support ribs 5, and further improve the overall strength of the stator support structure component 2.

[0079] Furthermore, such as Figure 4 As shown, both ends of the second reinforcing plate 62 in the radial direction of the stator are recessed towards the interior of the second reinforcing plate 62 in the radial direction of the stator, so as to prevent stress concentration at the welding point of the second reinforcing plate 62 and the support rib 5, improve the welding effect, and ensure the overall structural strength of the stator support structure component 2.

[0080] In other alternative embodiments, only one end of the second reinforcing plate 62 in the radial direction of the stator may be recessed towards the interior of the second reinforcing plate 62 in the radial direction of the stator.

[0081] like Figures 2-4 As shown, the third reinforcing plate 63 is disposed between the fixed plate 4 and the supporting rib 5 adjacent to the fixed plate 4. The two ends of the third reinforcing plate 63 in the circumferential direction of the stator are respectively connected to the side plate 52 of the fixed plate 4 and the supporting rib 5 facing the fixed plate 4. The third reinforcing plate 63 can further improve the radial and tangential rigidity of the supporting rib 5, and further improve the overall strength of the stator support structure component 2.

[0082] Furthermore, such as Figure 4 As shown, both ends of the third reinforcing plate 63 in the radial direction of the stator are recessed towards the interior of the third reinforcing plate 63 in the radial direction of the stator, so as to prevent stress concentration at the welding points of the third reinforcing plate 63 and the support rib 5, and the welding points of the third reinforcing plate 63 and the fixing plate 4, thereby improving the welding effect and ensuring the overall structural strength of the stator support structure component 2.

[0083] In other alternative embodiments, only one end of the third reinforcing plate 63 in the radial direction of the stator may be recessed towards the interior of the third reinforcing plate 63 in the radial direction of the stator.

[0084] In other alternative embodiments, the first reinforcing plate 61 and / or the second reinforcing plate 62 and / or the third reinforcing plate 63 may not be designed with a recessed structure at either end in the radial direction of the stator.

[0085] In this embodiment, the first reinforcing plate 61 and the supporting rib 5, the second reinforcing plate 62 and the supporting rib 5, the third reinforcing plate 63 and the supporting rib 5, and the third reinforcing plate 63 and the fixing plate 4 are all fixedly connected by welding to improve the structural strength of the stator support structure component 2.

[0086] like Figures 2-4 As shown, in this embodiment, a plurality of first reinforcing plates 61 are spaced apart along the axial direction of the stator within the groove 523 of a single support rib 5. A plurality of second reinforcing plates 62 are spaced apart along the axial direction of the stator between two adjacent support ribs 5 in the circumferential direction of the stator. A plurality of third reinforcing plates 63 are spaced apart along the axial direction of the stator between adjacent support ribs 5 and fixing plates 4 in the circumferential direction of the stator. The number of reinforcing plates in each row is the same. The first reinforcing plates 61, second reinforcing plates 62, and third reinforcing plates 63 are located at the same position in the axial direction of the stator support structure component 2, that is, the first reinforcing plate 61, the corresponding second reinforcing plate 62, and the corresponding third reinforcing plate 63 can be located in the same plane perpendicular to the axial direction of the stator. Thus, under the action of the tangential force generated by the wind turbine torque on the stator, the tangential force can be effectively transmitted between two adjacent reinforcing plates in the circumferential direction of the stator, resisting the compressive force exerted by the reinforcing plates on the support ribs, avoiding deformation of the support ribs, and enhancing the rigidity of the stator support structure component. If the first reinforcing plate 61, the second reinforcing plate 62, and the third reinforcing plate 63 are misaligned in the axial direction of the stator, the reinforcing plates will directly compress the side plate 52 of the support rib 5, causing the support rib 5 to deform.

[0087] In this embodiment, "each row of reinforcing plates" refers to a plurality of first reinforcing plates 61, a plurality of second reinforcing plates 62, or a plurality of third reinforcing plates 63 located at the same circumferential position of the stator and spaced apart along the axial direction of the stator.

[0088] like Figure 5 As shown, the included angle between the connecting plate 51 and the side plate 52 is defined as α, and in this embodiment, the included angle α is specifically 105°. On the one hand, this angle can ensure the structural strength of the support rib 5 and resist the deformation caused by electromagnetic force during the operation of the wind turbine. On the other hand, this angle can ensure that there is sufficient space between two adjacent support ribs 5 in the circumferential direction of the stator to achieve ventilation and cooling of the stator core 1. In addition, this angle can also prevent the distance between the ends of the two side plates 52 away from the connecting plate 51 in the circumferential direction of the stator from being too small, so as to facilitate the welding of the support rib 5 to the axial end plate 3.

[0089] In other alternative implementations, the included angle α can also be 100°, 120°, 150° or other angles, as long as 90°≤α<180° is satisfied, and it is further preferred to control it between 100° and 150°.

[0090] Specifically, such as Figure 4 As shown, the multiple support ribs 5 are divided into first support ribs 53 and second support ribs 54. In the circumferential direction of the stator, the support ribs 5 adjacent to the fixing plate 4 are the first support ribs 53, and the remaining support ribs 5 located between the two first support ribs 53 are the second support ribs 54. In this embodiment, the second support ribs 54 have a symmetrical structure, with the same angle between the two side plates 52 and the connecting plate 51. The first support ribs 53 have an asymmetrical structure, with different angles between the two side plates 52 and the connecting plate 51.

[0091] like Figure 6 As shown, the side plate 52 of the first support rib 53 on the side of the stator closer to the corresponding fixed plate 4 in the circumferential direction is defined as the first side plate 521, and the side plate 52 of the first support rib 53 on the side of the stator farther away from the corresponding fixed plate 4 in the circumferential direction is defined as the second side plate 522. The included angle α1 between the first side plate 521 and the connecting plate 51 is less than or equal to the included angle α2 between the second side plate 522 and the connecting plate 51, so as to ensure that there is a sufficient gap between the support rib 5 and the fixed plate 4, so as to reserve enough welding space for the third reinforcing plate 63, thereby reducing the welding difficulty and welding cost.

[0092] In other alternative embodiments, the first support rib 53 and the second support rib 54 can both be symmetrical structures, or the first support rib 53 can be symmetrical and the second support rib 54 can be asymmetrical, depending on the actual situation. Symmetrical support ribs 5 eliminate the need to identify the installation direction during installation, improving installation efficiency.

[0093] In other alternative embodiments, the stator support structure described above is also applicable to stator structures in the form of an outer stator. In this state, the stator support structure is sleeved on the outer periphery of the stator core 1, the rotor is located on the inner periphery of the stator, and the opening of the groove 523 faces the radial outer side of the stator in the radial direction of the stator.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
