Description

Technical Field

[0002] A wind turbine generator set (abbreviated as wind turbine) is a system that converts the kinetic energy of wind into electrical energy. A wind turbine generator set usually includes a wind turbine body and a tower. The tower is connected to the wind turbine body through an elastic support device to achieve reliable support and buffer shock absorption for the wind turbine body, avoiding damage or even fracture of the structure at the connection between the wind turbine body and the tower.

[0003] In the prior art, the elastic support device is usually a spring arranged between the wind turbine body and the tower. The vertical vibration of the wind turbine body can be buffered by the vertical expansion and contraction of the spring.

[0061] like Figures 1 to 8As shown, the present application provides an elastic support device for a wind turbine, comprising: a unit mounting seat 1 and a shell assembly 2 arranged along a first direction, and a transverse buffer support mechanism 3, a vertical buffer support mechanism 4 and a circumferential buffer support mechanism 5 arranged in sequence between the unit mounting seat 1 and the shell assembly 2 along the first direction, the circumferential buffer support mechanism 5 being close to the unit mounting seat 1; the shell assembly 2 comprises a first bottom wall 21 arranged perpendicular to the first direction and a first circumferential wall 22 arranged around the first bottom wall 21; the vertical buffer support mechanism 4 comprises a first fixed plate 41, a second fixed plate 42 and a first spring 43, the first fixed plate 41 and the second fixed plate 42 being arranged at intervals along the first direction; the first spring 43 is arranged between the first fixed plate 41 and the second fixed plate 42, and the vertical movement of the unit mounting seat 1 is buffered by the elastic action of the first spring 43; the transverse buffer support mechanism 3 comprises a sliding column 31 and a plurality of telescopic components 6, the sliding column 31 is cylindrical, and one end of the sliding column 31 along the first direction is slidably connected to the first bottom wall 21, and the other end The first fixed plate 41 is fixedly connected; a plurality of telescopic components 6 are arranged at intervals along the circumference of the sliding column 31, and the telescopic components 6 extend radially along the sliding column 31. One end of the telescopic component 6 close to the sliding column 31 is fixedly connected to the sliding column 31, and the telescopic component 6 is fixedly connected to the first peripheral wall 22 on the side away from the telescopic component 6, and the lateral movement of the unit mounting seat 1 is buffered by the telescopic effect of the telescopic component 6; the circumferential buffer support mechanism 5 includes a connecting column 51, a connecting plate 52 and a plurality of telescopic components 6, the connecting column 51 and the connecting plate 52 are arranged along the first direction and connected to each other, the connecting column 51 is cylindrical and rotatably connected to the second fixed plate 42, and the connecting plate 52 is fixedly connected to the unit mounting seat 1; a plurality of telescopic components 6 are arranged at intervals along the circumference of the connecting column 51, and the telescopic components 6 extend tangentially along the connecting column 51. One end of the telescopic component 6 close to the connecting column 51 is movably connected to the connecting column 51, and the telescopic component 6 is movably connected to the first peripheral wall 22 on the side away from the telescopic component 6, and the circumferential movement of the unit mounting seat 1 is buffered by the telescopic effect of the telescopic component 6.

[0062] In the embodiment of the present application, a transverse buffer support mechanism 3, a vertical buffer support mechanism 4 and a circumferential buffer support mechanism 5 are provided between the unit mounting seat 1 and the shell assembly 2. In this way, when the wind turbine body is installed on the unit mounting seat 1 and the shell assembly 2 is connected to the tower 9, when the wind turbine body moves laterally relative to the tower 9, the transverse buffer support mechanism 3 plays a buffering role, thereby reducing the impact of the lateral vibration on the wind turbine body. When the wind turbine body moves vertically relative to the tower 9, the vertical buffer support mechanism 4 plays a buffering role, thereby reducing the impact of the vertical vibration on the wind turbine body. When the wind turbine body rotates relative to the tower 9, the circumferential buffer support mechanism 5 plays a buffering role, thereby reducing the impact of the rotation on the wind turbine body. In summary, the elastic support device of the wind turbine unit in the embodiment of the present application can buffer the vibration of the wind turbine body in all directions, so that the wind turbine body can be stably supported and buffered.

[0063] Specifically, since the first spring 43 is arranged between the first fixed plate 41 and the second fixed plate 42, the vertical movement of the unit mounting seat 1 and the wind turbine body can be buffered by the elastic action of the first spring 43, thereby reducing or eliminating the influence of vertical vibration on the wind turbine body. Specifically, when vertical vibration occurs, that is, when the wind turbine body moves vertically, an external force acting on the first spring 43 will be generated. The first spring 43 will undergo elastic deformation (such as stretching or compression) and store energy after being acted upon by an external force; when the external force disappears, the first spring 43 will return to its original shape and release the stored energy. That is, the process of storing and releasing energy by the first spring 43 can effectively buffer vertical vibration, thereby reducing or eliminating the influence of vertical vibration on the wind turbine body. A plurality of telescopic components 6 are arranged at circumferential intervals on the sliding column 31, and the telescopic components 6 extend along the radial direction of the sliding column 31, that is, telescopic components 6 are arranged on different radial directions of the sliding column 31. In this way, when lateral vibration occurs, that is, when the sliding column 31 moves horizontally in different radial directions, each telescopic component 6 can be adaptively telescoped to buffer the movement of the sliding column 31, thereby improving the lateral buffering effect of the sliding column 31, which is beneficial to improving the seismic resistance of the wind turbine body. By arranging multiple telescopic components 6 at circumferential intervals on the connecting column 51, and the telescopic components 6 extend along the tangential direction of the connecting column 51, that is, telescopic components 6 are arranged in different tangential directions of the connecting column 51. In this way, when the wind turbine body rotates and drives the connecting column 51 to rotate, each telescopic component 6 can be adaptively telescoped to absorb the rotational energy, thereby buffering the rotation of the wind turbine body, and releasing energy when the rotational force disappears to return the wind turbine body to its original position, preventing the connection from being damaged or even broken due to excessive force.

[0064] In summary, when lateral vibration occurs, the vibration force of the wind turbine body will be transmitted to the circumferential buffer support mechanism 5, the vertical buffer support mechanism 4 and the lateral buffer support mechanism 3 in sequence. The telescopic component of the lateral buffer support mechanism 3 can absorb the vibration energy, thereby buffering the vertical movement of the wind turbine body, thereby reducing or eliminating the impact of the lateral vibration on the wind turbine body. When vertical vibration occurs, the vibration force of the wind turbine body will be transmitted to the circumferential buffer support mechanism 5 and the vertical buffer support mechanism 4 in sequence. The first spring of the vertical buffer support mechanism 4 can absorb the vibration energy, thereby buffering the vertical movement of the wind turbine body, thereby reducing or eliminating the impact of the vertical vibration on the wind turbine body. In the case of strong winds, the wind wheel of the wind turbine body encounters uneven wind, causing the wind turbine body to rotate to one side in the horizontal direction, that is, to rotate on the horizontal plane, which will cause the connection between the wind turbine body and the elastic support mechanism to be overstressed and damaged or even broken. In this case, the rotational force of the wind turbine body can be transmitted to the circumferential buffer support mechanism 5, and the telescopic components of the circumferential buffer support mechanism 5 can absorb the rotational energy, thereby buffering the rotation of the wind turbine body and releasing energy when the rotational force disappears to return the wind turbine body to its original position, thereby preventing the connection from being damaged or even broken due to excessive force.

[0065] In practical applications, the wind turbine body of the embodiment of the present application is the core component of the wind turbine set, mainly including the wind rotor, transmission system, generator and other parts, and the wind energy is converted into electrical energy through the coordinated work of various parts. The tower 9 is the main load-bearing component in the wind turbine set, providing a stable support platform for the wind rotor and the like and placing the wind rotor in a higher position to improve the efficiency of wind energy capture. In one of the embodiments, the wind turbine body and the unit mounting seat 1, the tower 9 and the shell assembly 2 are connected by welding to improve the connection reliability of various parts in the wind turbine set. In addition, in the embodiment of the present application, the horizontal direction refers to the horizontal direction, and the vertical direction refers to the vertical direction, that is, the direction of the X-axis. The horizontal buffer support mechanism 3, the vertical buffer support mechanism 4 and the circumferential buffer support mechanism 5 of the embodiment of the present application are independent of each other. Under different vibration conditions of the wind turbine body, that is, when the wind turbine body moves differently relative to the tower 9, the three can work separately or in coordination according to the actual movement of the wind turbine body.

[0066] It should be noted that the embodiment of the present application does not limit the number of telescopic components 6, and those skilled in the art can adjust it according to actual needs. It can be understood that, taking the lateral buffer support mechanism 3 as an example, when the sliding column 31 moves in a certain direction, each telescopic component 6 will have a certain force in that direction, that is, each telescopic component 6 will expand and contract, but the degree of expansion and contraction is different. In one embodiment, Figure 2As shown, the lateral buffer support mechanism 3 is provided with eight telescopic components 6, and the eight telescopic components 6 are arranged at uniform intervals along the circumference of the sliding column 31. The circumferential buffer support mechanism 5 is provided with four telescopic components 6, and the four telescopic components 6 are arranged at uniform intervals along the circumference of the connecting column 51. In addition, the fixed connection method between the connecting plate 52 and the unit mounting seat 1 in the embodiment of the present application includes but is not limited to welding, threaded connection, clamping, riveting, etc., and those skilled in the art can adjust according to actual needs. In one embodiment, the connecting plate 52 is threadedly connected to the unit mounting seat 1.

[0067] In addition, in the embodiment of the present application, the fixed connection method of the sliding column 31 and the first fixed plate 41, the connecting plate 52 and the unit mounting seat 1 includes but is not limited to welding, threaded connection, clamping, riveting, etc., and those skilled in the art can adjust it according to actual needs. In one embodiment, the sliding column 31 is connected to the first fixed plate 41 by welding, and the connecting plate 52 is connected to the unit mounting seat 1 by threaded connection. In addition, the housing assembly 2 also includes a sliding support plate 23, the sliding support plate 23 is fixedly connected to the first bottom wall 21, and the sliding column 31 is slidably connected to the sliding support plate 23. In order to further reduce the friction between the sliding column 31 and the sliding support plate 23, the side surface of the sliding support plate 23 and the sliding column 31 that are close to each other can be smoothed to reduce the surface roughness. Among them, the smoothing method includes but is not limited to polishing, sandblasting, etc., which is not limited here, and those skilled in the art can choose according to actual needs.

[0068] In some optional embodiments of the present application, the vertical buffer support mechanism 4 also includes: a first seismic isolation pad 44 and a sliding rod 45; the first seismic isolation pad 44 is passed through the first spring 43 and is respectively connected to the first fixed plate 41 and the second fixed plate 42; the sliding rod 45 is fixedly connected to the first fixed plate 41 and slidably connected to the second fixed plate 42, so that the second fixed plate 42 moves along the first direction X toward or away from the first fixed plate 41.

[0069] In the embodiment of the present application, by providing the first seismic isolation pad 44, on the one hand, the load of the upper wind turbine body and other components can be distributed smoothly and evenly, which is beneficial to improving the support stability of the vertical buffer support mechanism. On the other hand, the vibration energy can be absorbed, thereby reducing or eliminating the impact of the vibration on the wind turbine body. By providing the sliding rod 45, the second fixed plate 42 can be guided to move along the first direction X, that is, the vertical direction, so as to avoid the second fixed plate 42 from tilting during the movement, which affects the buffering effect of the vertical buffer support mechanism 4.

[0070] It should be noted that the first seismic isolation pad 44 refers to a structure that can undergo elastic deformation to absorb vibration, including but not limited to a rubber buffer pad. In order to improve the stability of the second fixed disk 42 moving in the vertical direction, a plurality of sliding rods 45 are usually provided, and the plurality of sliding rods 45 are arranged at intervals along the circumference of the first fixed disk 41. The embodiment of the present application does not limit the number of sliding rods 45, and those skilled in the art can adjust it according to actual needs. In one of the embodiments, six sliding rods 45 are provided, and the six sliding rods 45 are arranged at uniform intervals along the circumference of the first fixed disk 41, and the first spring 43 and the first seismic isolation pad 44 are both located on the inner side of the sliding rod 45. In addition, in one of the embodiments, the second fixed disk 42 is provided with a through hole, and the sliding rod 45 is inserted into the through hole. The movement of the second fixed disk 42 can be guided by the sliding connection between the sliding rod 45 and the through hole, so that the second fixed disk 42 moves along the first direction X, that is, the vertical direction, to achieve vertical buffering of the wind power body. Furthermore, the sliding rod 45 is also provided with a limit block, and the limit block is located on a side of the second fixed plate 42 away from the first fixed plate 41 , so as to limit the vertical movement stroke of the second fixed plate 42 .

[0071] In some optional embodiments of the present application, such as Figure 3 As shown, the vertical buffer support mechanism 4 also includes: a fixed shell 46; the fixed shell 46 is arranged on the side of the second fixed disk 42 away from the first fixed disk 41, and the fixed shell 46 is provided with a connecting groove; the circumferential buffer support mechanism 5 is provided with a T-shaped connecting block 54 at the corresponding position of the connecting groove, and the T-shaped connecting block 54 is embedded in the connecting groove and rotatably connected to the connecting groove. Specifically, the T-shaped connecting block 54 is arranged on the side of the connecting column 51 away from the connecting disk 52 and is fixedly connected to the connecting column 51.

[0072] In the embodiment of the present application, since the fixed shell 46 is provided with a connection groove, the circumferential buffer support mechanism 5 and the vertical buffer support mechanism 4 can be rotatably connected by embedding the T-shaped connection block 54 in the connection groove and rotatably connecting with the connection groove. It should be noted that the cross section of the T-shaped connection block 54 parallel to the first direction X is T-shaped, and the shape of the T-shaped connection block 54 should be compatible with the shape of the connection groove. In addition, the fixed shell 46 is located on the inner side of the plurality of sliding rods 45 to prevent the fixed shell 46 and the sliding rods 45 from interfering with each other during the operation of the vertical buffer support mechanism 4.

[0073] In some optional embodiments of the present application, such as Figure 3 , Figure 5 as well as Figure 7 As shown, the lateral buffer support mechanism 3 also includes: a plurality of first connecting members 32; the sliding column 31 and / or the first peripheral wall 22 are provided with first connecting members 32 at corresponding positions of the telescopic assembly 6, and the first connecting members 32 are detachably connected to the telescopic assembly 6.

[0074] In practical applications, the telescopic assembly 6 is the core component of the lateral buffer support mechanism 3. The telescopic assembly 6 can buffer the lateral movement of the wind turbine body through its own telescopic movement, thereby reducing or eliminating the impact of lateral vibration on the wind turbine body. It can be seen that the telescopic assembly 6 is usually a consumable part. By detachably connecting the telescopic assembly 6 to the first connecting member 32, the telescopic assembly 6 can be quickly disassembled for maintenance and replacement, which is conducive to improving maintenance work efficiency and reducing maintenance costs.

[0075] It should be noted that the embodiment of the present application does not limit the number of first connecting members 32, and those skilled in the art can adjust it according to actual needs. It is understandable that for the lateral buffer support mechanism 3, since both ends of a telescopic component 6 are respectively connected to a first connecting member 32, the number of first connecting members 32 should be twice the number of telescopic components 6. In one embodiment, Figure 5 and Figure 7 As shown, the lateral buffer support mechanism 3 includes sixteen first connecting members 32, eight of which are arranged on the sliding column 31, and the other eight first connecting members 32 are arranged on the first peripheral wall 22, and a telescopic component 6 is respectively connected to a first connecting member 32 arranged on the sliding column 31 and a first connecting member 32 arranged on the first peripheral wall 22.

[0076] In some optional embodiments of the present application, the first connecting member 32 includes: a first connecting block 321 and a first plug-in block 322; the first connecting block 321 is fixedly connected to the sliding column 31, and the first plug-in block 322 is arranged on the side of the first connecting block 321 away from the sliding column 31; and / or the first connecting block 321 is fixedly connected to the first peripheral wall 22, and the first plug-in block 322 is arranged on the side of the first connecting block 321 away from the first peripheral wall 22; the first plug-in block 322 is provided with one of the plug-in block 7 or the slot 8, the telescopic assembly 6 is provided with the other of the plug-in block 7 or the slot 8, and the plug-in block 7 is plugged into the slot 8.

[0077] In the embodiment of the present application, since the first plug-in block 322 is provided with one of the slot 8 or the plug-in block 7, the telescopic assembly 6 is provided with the other of the slot 8 or the plug-in block 7. In this way, the first connecting member 32 and the telescopic assembly 6 can be reliably connected by plugging the plug-in block 7 with the slot 8, and this connection structure is simple, which is conducive to simplifying the structure of the lateral buffer support mechanism 3 and reducing the production cost.

[0078] It should be noted that the embodiment of the present application only shows the case where the first plug-in block 322 is provided with the slot 8 and the telescopic assembly 6 is provided with the plug-in block 7. In actual applications, those skilled in the art may also provide the plug-in block 7 to the first plug-in block 322 and the slot 8 to the telescopic assembly 6. This is not limited here, and those skilled in the art may adjust according to actual needs. In one embodiment, the plug-in block 7 is a U-shaped plug-in block 7.

[0079] In some optional embodiments of the present application, the circumferential buffer support mechanism 5 also includes: a plurality of second connecting members 53; the connecting column 51 and / or the first circumferential wall 22 are provided with second connecting members 53 at corresponding positions of the telescopic assembly 6, and the second connecting members 53 are detachably connected to the telescopic assembly 6.

[0080] In practical applications, the telescopic assembly 6 is the core component of the circumferential buffer support mechanism 5. The telescopic assembly 6 can buffer the rotation of the wind turbine body through its own telescopic expansion, reduce the impact of uneven wind on the wind turbine body, and prevent the connection from being damaged or even broken due to excessive force. It can be seen that the telescopic assembly 6 is usually a consumable part. By detachably connecting the telescopic assembly 6 to the second connecting member 53, the telescopic assembly 6 can be quickly disassembled for maintenance and replacement, which is conducive to improving maintenance work efficiency and reducing maintenance costs.

[0081] It should be noted that the embodiment of the present application does not limit the number of second connecting members 53, and those skilled in the art can adjust it according to actual needs. It is understandable that for the circumferential buffer support mechanism 5, since both ends of a telescopic component 6 are respectively connected to a second connecting member 53, the number of second connecting members 53 should be twice the number of telescopic components 6. In one embodiment, Figure 6 and Figure 8 As shown, the circumferential buffer support mechanism 5 includes eight second connecting members 53, four of which are arranged on the connecting column 51, and the other four first connecting members 32 are arranged on the fixing ring 24, and a telescopic assembly 6 is respectively connected to a second connecting member 53 arranged on the connecting column 51 and a second connecting member 53 arranged on the fixing ring 24.

[0082] In some optional embodiments of the present application, the second connecting member 53 includes: a bracket 531, a second connecting block 532 and a second plug-in block 533; the bracket 531 is fixedly connected to the connecting column 51; and / or the bracket 531 is fixedly connected to the first peripheral wall 22; the second connecting block 532 is rotatably connected to the bracket 531; the second plug-in block 533 is arranged at the end of the second connecting block 532 away from the bracket 531, the second plug-in block 533 is provided with one of the plug-in block 7 or the slot 8, the telescopic assembly 6 is provided with the other of the plug-in block 7 or the slot 8, and the plug-in block 7 is plugged into the slot 8.

[0083] In the embodiment of the present application, on the one hand, since the second plug-in block 533 is provided with one of the slot 8 or the plug-in block 7, the telescopic assembly 6 is provided with the other of the slot 8 or the plug-in block 7, wherein the slot 8 and the plug-in block 7 are adapted, that is, the external dimension structure of the part where the plug-in block 7 and the slot 8 are plugged is consistent with the internal dimension structure of the slot 8. In this way, the reliable connection between the second connecting member 53 and the telescopic assembly 6 can be achieved by plugging the plug-in block 7 and the slot 8, and this connection structure is simple, which is conducive to simplifying the structure of the circumferential buffer support mechanism 5 and reducing the production cost. On the other hand, when the rotation occurs, the telescopic assembly 6 no longer extends along the tangent direction of the connecting column 51, that is, there is a certain angle between the extension direction of the telescopic assembly 6 and the tangent direction of the connecting column 51. Based on this, when the second connecting block 532 is rotatably connected to the bracket 531, the bracket 531 fixedly connected to the connecting column 51 will not interfere with the telescopic movement of the telescopic assembly 6, which is conducive to improving the buffering effect of the circumferential buffer support assembly.

[0084] It should be noted that the embodiment of the present application only shows the case where the second plug-in block 533 is provided with a slot 8 and the telescopic assembly 6 is provided with a plug-in block 7. In actual applications, those skilled in the art may also provide the plug-in block 7 to the second plug-in block 533 and the slot 8 to the telescopic assembly 6. This is not limited here, and those skilled in the art may make adjustments according to actual needs. In one embodiment, the plug-in block 7 is a U-shaped plug-in block 7, the bracket 531 is a U-shaped bracket 531, and the opening of the U-shaped bracket 531 faces the side away from the connecting column 51. The U-shaped bracket 531 includes two fixing rods spaced apart along the first direction X, and the corresponding positions of the fixing rods are provided with pin holes extending along the first direction X. Correspondingly, the second connecting block 532 is provided with pins on both sides along the first direction X, and one pin is rotatably connected to one pin hole, thereby realizing the rotational connection between the second connecting block 532 and the bracket 531.

[0085] In some optional embodiments of the present application, such as Figures 9 and 10 As shown, the extension direction of the telescopic component 6 is the second direction Y, and the telescopic component 6 includes: a shell 61, a sliding block 62, a second isolation pad 63, a second spring 64 and two third connecting members 65; the shell 61 includes a second bottom wall 611 arranged perpendicular to the second direction Y and a second peripheral wall 612 surrounding the second bottom wall 611; the sliding block 62 is slidably connected to the second peripheral wall 612 along the second direction Y; the second isolation pad 63 is arranged between the sliding block 62 and the second bottom wall 611; the second spring 64 is sleeved on the second isolation pad 63; the two third connecting members 65 are respectively arranged at the ends of the sliding block 62 and the second bottom wall 611 that are away from each other, and the third connecting member 65 is used to be detachably connected to the first connecting member 32 or the second connecting member 53.

[0086] In the embodiment of the present application, on the one hand, due to the provision of the second spring 64, the elastic action of the second spring 64 can buffer the lateral movement and / or circumferential movement of the unit mounting seat 1 and the wind turbine body, thereby reducing or eliminating the influence of lateral vibration on the wind turbine body. Specifically, when lateral vibration or rotation occurs, that is, the wind turbine body will generate an external force acting on the second spring 64. After being acted upon by an external force, the second spring 64 will undergo elastic deformation (such as stretching or compression) and store energy, thereby buffering the lateral vibration or rotation of the wind turbine body; when the external force disappears, the first spring 43 will return to its original shape and release the stored energy, thereby driving the wind turbine body to return to its original shape, reducing or eliminating the influence of lateral vibration or rotation on the wind turbine body. On the other hand, due to the provision of the second seismic isolation pad 63, the lateral vibration or rotation energy can be absorbed, further reducing or eliminating the influence of lateral vibration or rotation on the wind turbine body, which is beneficial to improving the buffering effect of the lateral buffer support mechanism 3 and the circumferential buffer support mechanism 5.

[0087] It should be noted that the second seismic isolation pad 63 refers to a structure that can undergo elastic deformation to absorb vibration, including but not limited to a rubber buffer pad. In one embodiment, the shell 61 also includes a second top wall 613, and the second top wall 613 and the second bottom wall 611 are spaced apart along the second direction Y. The second top wall 613 is provided with a mounting hole, and the third connecting member 65 arranged near the sliding block 62 is also provided with a connecting rod 651, and the connecting rod 651 is passed through the mounting hole, and the two ends of the connecting rod 651 along the second direction Y are respectively connected to the plug block 7 or the slot 8 of the third connecting member 65 and the sliding block 62. Among them, a gap can be set between the mounting hole and the connecting rod 651, and between the sliding block 62 and the second peripheral wall 612, so that the third connecting members 65 at both ends of the telescopic assembly 6 can shake relative to each other. Taking the transverse buffer support mechanism 3 as an example, when the sliding column 31 moves along a specific direction, when the third connecting parts 65 at both ends of the telescopic component 6 can swing relatively, the interference of other telescopic components 6 set at an angle to the moving direction can be reduced, which is beneficial to improving the buffering effect of the transverse buffer support mechanism 3.

[0088] In some optional embodiments of the present application, the first connector 32 or the second connector 53 is provided with one of the plug block 7 or the slot 8; the third connector 65 is provided with the other of the plug block 7 or the slot 8, and the plug block 7 is plugged into the slot 8. In this way, the first connector 32 and the third connector 65, or the second connector 53 and the third connector 65 can be reliably connected by plugging the plug block 7 into the slot 8.

[0089] In some optional embodiments of the present application, a first threaded hole 71 and a second threaded hole 81 are provided at corresponding positions of the plug block 7 and the slot 8; the telescopic assembly 6 also includes a fastener, which is threadedly connected to the first threaded hole 71 and the second threaded hole 81 respectively.

[0090] In actual applications, due to the existence of processing errors, the plug block 7 and the slot 8 usually have an assembly gap, which may cause the plug block 7 and the slot 8 to shake relative to each other. Based on this, since the first threaded hole 71 and the second threaded hole 81 are provided at the corresponding positions of the plug block 7 and the slot 8, the plug block 7 and the slot 8 can be reliably fixed together through the threaded connection between the fastener and the first threaded hole 71 and the second threaded hole 81, and the shaking problem of both can be effectively avoided. In one embodiment, a mounting block is provided on the side of the U-shaped plug block 7 facing away from the outlet, and the first threaded hole 71 is opened on the mounting block. Correspondingly, the slot 8 includes a side wall perpendicular to the second direction Y, and the second threaded hole 81 is opened on the side wall.

[0091] In some optional embodiments of the present application, the housing assembly 2 further includes a fixing ring 24, which is disposed on the inner side of the first peripheral wall 22, and the side of the fixing ring 24 close to the first peripheral wall 22 is slidably connected to the first peripheral wall 22, and the side of the fixing ring 24 away from the first peripheral wall 22 is connected to the circumferential buffer support mechanism 5. Specifically, at least part of the second connecting member 53 is disposed on the side of the fixing ring 24 away from the first peripheral wall 22, and the connection between the telescopic assembly 6 and the second connecting member 53 can realize the connection between the fixing ring 24 and the circumferential buffer support assembly.

[0092] In the embodiment of the present application, since the fixing ring 24 is provided, the fixing ring 24 is connected to the circumferential buffer support mechanism 5 and is slidably connected to the first peripheral wall 22. In this way, the vertical buffer support mechanism 4 can be guided to move along the first direction X.

[0093] Further, the peripheral wall is provided with one of a slide groove 221 or a slider 241 extending along the first direction X, and the side of the fixed ring 24 close to the peripheral wall is provided with the other of the slide groove 221 or the slider 241 extending along the first direction X, and the slide groove 221 is slidably connected with the slider 241 along the first direction X. It should be noted that the present application does not limit the number and position of the slide grooves 221 and the slider 241, and those skilled in the art can adjust according to actual needs. In one embodiment, eight sliders 241 are provided, and the eight sliders 241 are arranged at intervals along the circumference of the fixed ring 24, and correspondingly, eight slide grooves 221 are provided, and the eight slide grooves 221 are arranged at intervals along the circumference of the first peripheral wall 22, and one slide groove 221 is slidably connected with one slider 241 along the first direction X.

[0094] In summary, the wind turbine elastic support device provided in the embodiment of the present application has at least the following advantages:

[0095] In the embodiment of the present application, a transverse buffer support mechanism, a vertical buffer support mechanism and a circumferential buffer support mechanism are provided between the unit mounting seat and the shell assembly. In this way, when the wind turbine body is installed on the unit mounting seat and the shell assembly is connected to the tower, when the wind turbine body moves laterally relative to the tower, the transverse buffer support mechanism plays a buffering role, thereby reducing the impact of the lateral vibration on the wind turbine body. When the wind turbine body moves vertically relative to the tower, the vertical buffer support mechanism plays a buffering role, thereby reducing the impact of the vertical vibration on the wind turbine body. When the wind turbine body rotates relative to the tower, the circumferential buffer support mechanism plays a buffering role, thereby reducing the impact of the rotation on the wind turbine body. In summary, the elastic support device of the wind turbine unit in the embodiment of the present application can buffer the vibration of the wind turbine body in all directions, so that the wind turbine body can be stably supported and buffered.
