[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0032] According to an embodiment of the present invention, in one aspect, a platform structure is provided, which is disposed within a tower (not shown in the figure), the tower having an inner wall. For example... Figures 1-3 As shown, the platform structure includes a platform 1 and a first connecting component 2, which is connected between the platform 1 and the inner wall of the tower.

[0033] Specifically, in combination Figures 4-6The first connecting assembly 2 includes a swing arm 22, a connecting rod 21, and a first connecting member 23. One end of the swing arm 22 is rotatably connected to the platform 1 about a first direction X. The connecting rod 21 is rotatably connected to the end of the swing arm 22 away from the platform 1 about the first direction X. That is, both ends of the swing arm 22 are rotatably connected to the platform 1 and the connecting rod 21, respectively. A movable space 213 extending along a second direction Y is formed within the connecting rod 21. One end of the first connecting member 23 is movably connected to the movable space 213, and the other end is used to connect to the inner wall of the tower. The second direction Y is perpendicular to the inner wall of the tower, and the first direction X intersects the second direction Y. In some cases, the first direction X may be perpendicular to the second direction Y.

[0034] In this embodiment, platform 1 forms a four-bar linkage 21 structure with the inner wall of the tower via connecting rod 21, swing rod 22, and first connecting member 23. This allows platform 1 to swing with the tower to a certain amplitude when the tower sways, thus providing a buffer and resisting damage to the connection between the inner wall of the tower and platform 1 caused by the tower swaying. In other words, the flexible connection between the inner wall of the tower and platform 1 in this invention solves the problem of connecting plate breakage in related technologies and improves the reliability of the connection.

[0035] Understandably, in some cases, the tower is a conical structure, in which case the second direction Y is perpendicular to the inner wall of the tower, and the second direction Y is also the radial direction of the tower. In other cases, the first direction X can be perpendicular to the second direction Y, and the first direction X is either the circumferential direction of the tower or a tangent direction tangent to the circumferential direction of the tower.

[0036] In some embodiments, platform 1 includes platform plate 11, which is a circular plate structure adapted to the shape of the inner wall of the tower. In this case, the second direction Y is the radial direction of platform plate 11, and the first direction X is the circumferential direction of platform plate 11 or the tangential direction tangent to the circumferential direction of platform plate 11.

[0037] Specifically, the platform plate 11 includes an upper surface 111 and a lower surface 112 disposed opposite to each other, and an outer surface 114 connecting the upper surface 111 and the lower surface 112. The circumferential direction of the platform plate 11 is also the direction of extension of the outer surface 114 of the platform plate 11.

[0038] Understandably, the present invention does not specifically limit the shape and structure of the platform plate 11, as long as it can be installed in the tower to achieve the corresponding function. For example, the platform plate 11 can also be a rectangular plate structure, a polygonal plate structure, or other irregularly shaped plate structures.

[0039] Specifically, in some embodiments, the first connector 23 includes a first connecting portion 231 and a first limiting portion 232. The first connecting portion 231 is connected between the first limiting portion 232 and the inner wall of the tower, and the first connecting portion 231 is movably inserted within the active space 213. The first limiting portion 232 is located outside the active space 213 and is used to restrict the first connecting portion 231 from leaving the active space 213. Along the third direction Z, the cross-sectional dimension of the active space 213 is larger than the cross-sectional dimension of the first connecting portion 231. The third direction Z is perpendicular to the second direction Y. In this embodiment, the cross-sectional dimension of the active space 213 is larger than the cross-sectional dimension of the first connecting portion 231. The active space 213 can provide the first connecting portion 231 with degrees of freedom in all directions, allowing the first connector 23 to move relative to the connecting rod 21 with the swaying of the tower, thus providing a buffering effect and further improving the reliability of the connection between the platform 1 and the tower.

[0040] Understandably, the present invention does not specifically limit the shape and structure of the first connecting part 231, as long as it can be inserted into the movable space 213 and movably connected to the connecting rod 21. For example, the first connecting part 231 can be constructed as a cylinder, rod, prism, block, or other irregular shape, as long as the cross-sectional dimension of the movable space 213 along the third direction Z is greater than the cross-sectional dimension of the first connecting part 231. For example, if the first connecting part 231 is cylindrical, then the dimension of the movable space 213 in any direction along the third direction Z should be greater than the diameter of the first connecting part 231.

[0041] For example, the first connecting part 231 and the inner wall of the tower can be connected by bolts, welding, snap-fit, etc., preferably by welding, which provides higher connection strength and reliability.

[0042] For example, the connecting rod 21 has a first side 211 and a second side 212 disposed opposite to each other along the second direction Y. The first side 211 is close to the inner wall of the tower, and the second side 212 is away from the inner wall of the tower. The movable space 213 extends through the first side 211 and the second side 212. The movable space 213 forms an opening on the second side 212, and the size of the second limiting part 313 is larger than the size of the opening, so as to prevent the first connecting part 231 from disengaging from the movable space 213.

[0043] Understandably, the present invention does not specifically limit the shape and structure of the second limiting part 313 or the connection method between it and the first connecting part 231, as long as it can achieve the function of restricting the first connecting part 231 from leaving the active space 213.

[0044] For example, the second limiting portion 313 can be constructed as a circle, in which case the diameter of the second limiting portion 313 should be at least larger than the size of the opening in the first direction X. For example, the second limiting portion 313 can be constructed as a rectangular plate structure, in which case the length of the second limiting portion 313 should be at least larger than the maximum size of the opening.

[0045] For example, the first limiting part 232 and the first connecting part 231 can be integrally formed, or they can be connected as one piece by welding, bolting, threading, snap-fitting, etc. For example, as Figure 5 and Figure 7 As shown, the first connector 23 further includes a first fastening portion 233. Along the second direction Y, the first connecting portion 231 has a first threaded hole, and the first limiting portion 232 has a first through hole. The first fastening portion 233 passes through the first through hole of the first limiting portion 232 and connects with the first threaded hole in the first connecting portion 231 to connect the first connecting portion 231 and the first limiting portion 232 into one unit. For example, the first fastening portion 233 can be a bolt, and the first limiting portion 232 can be a washer.

[0046] Furthermore, in some embodiments, such as Figure 5 and Figure 6 As shown, the connecting rod 21 includes a first side portion 214, a second side portion 215, and a connecting portion 216. The first side portion 214 and the second side portion 215 are spaced apart along a first direction X, and the connecting portion 216 connects the first side portion 214 and the second side portion 215 to form a "U"-shaped structure. The ends of the first side portion 214 and the second side portion 215 furthest from the connecting portion 216 are rotatably connected to both sides of the swing rod 22 along the first direction X. The first side portion 214, the second side portion 215, and the connecting portion 216 together form the aforementioned active space 213. Exemplarily, the connecting portion 216 can be constructed as a circle, and the first connecting portion 231 can be constructed as a cylinder. Exemplarily, the first side portion 214, the second side portion 215, and the connecting portion 216 can be integrally formed.

[0047] Furthermore, in some embodiments, the first connecting assembly 2 further includes a first elastic element 24, one end of which is rotatably connected to the middle of the swing rod 22 about a first direction X, and the other end is connected to the inner wall of the tower. Understandably, the first elastic element 24 is located between the connecting rod 21 and the platform 1, and between the first connecting member 23 and the platform 1. In this embodiment, when the tower sways, part of the force can be converted into the elastic potential energy of the first elastic element 24 to provide a buffering effect, preventing rigid fracture at the connection between the platform 1 and the inner wall of the tower, and further improving the reliability of the connection between the platform 1 and the tower.

[0048] For example, such as Figure 5 and Figure 7 As shown, the first elastic element 24 includes a fourth connecting portion 241, an elastic portion 243, and a fifth connecting portion 242 connected in sequence. One end of the fourth connecting portion 241 is rotatably connected to the swing rod 22 about a first direction X, and the other end is fixedly connected to the elastic portion 243. One end of the fifth connecting portion 242 is connected to the elastic portion 243, and the other end is connected to the inner wall of the tower. By providing the fourth connecting portion 241, the reliability of the rotatable connection between the second elastic element 32 and the swing rod 22 is improved, and by providing the fifth connecting portion 242, the connection strength between the second elastic element 32 and the inner wall of the tower is improved.

[0049] For example, the fifth connection 242 can be connected to the inner wall of the tower by bolts, welding, snap-fit, etc., preferably by welding, which provides higher connection strength and reliability.

[0050] For example, both the fourth connecting portion 241 and the fifth connecting portion 242 may have a groove at one end facing the elastic portion 243, with both ends of the elastic portion 243 embedded in the groove and fixedly connected to the inner wall of the groove. For example, both the fourth connecting portion 241 and the fifth connecting portion 242 may have a boss at one end facing the elastic portion 243, with both ends of the elastic portion 243 sleeved outside the boss and fixedly connected to the outer wall of the boss. For example, one of the ends of the fourth connecting portion 241 and the fifth connecting portion 242 facing the elastic portion 243 may have a groove and the other a boss; one end of the elastic portion 243 may be embedded in the groove and fixedly connected to the inner wall of the groove, while the other end may be sleeved outside the boss and fixedly connected to the outer wall of the boss.

[0051] For example, the end of the fourth connecting part 241 away from the elastic part 243 may be provided with a connecting lug to facilitate rotational connection with the swing rod 22; the end face of the fifth connecting part 242 away from the elastic part 243 may have a flat or curved surface to facilitate close contact and connection with the inner wall of the tower.

[0052] For example, the elastic part 243 can be a spring. For example, the elastic part 243 can be in a compressed state.

[0053] Understandably, the platform 1 and the rocker arm 22, the connecting rod 21 and the rocker arm 22, and the second elastic part 243 and the rocker arm 22 are all rotatably connected by the pivot 25.

[0054] For example, three pivot members 25 may be provided. The first pivot member 25 passes through the connecting seat 13 on the platform 1 along the first direction X, so that the swing arm 22 can rotate relative to the platform 1 about the first direction X. The second pivot member 25 passes through the connecting rod 21 along the first direction X, so that the swing arm 22 and the connecting rod 21 can rotate relative to each other about the first direction X. The third pivot member 25 passes through the fourth connecting portion 241 of the second elastic member 32 along the first direction X, so that the swing arm 22 and the second elastic member 32 can rotate relative to each other about the first direction X.

[0055] For example, the pivot member 25 includes a pivot portion and end heads connected to both ends of the pivot portion. The two sides of the rocker arm 22 may be provided with first pads 26, which are sandwiched between the rocker arm 22 and the end heads.

[0056] For example, the shaft portion and the end head of the rotating shaft component 25 can be connected by a thread, and each of the three rotating shaft components 25 can be fitted with a bushing 27 (e.g., Figure 8 As shown, the connecting seat 13, connecting rod 21, and second elastic element 32 are all sleeved outside the bushing 27 to reduce or even eliminate the risk of the rotating shaft and end head becoming loose.

[0057] In some embodiments, the rocker arm 22 includes a first rocker arm 221 and a second rocker arm 222 spaced apart along a first direction X, both of which are constructed as plate-like structures. Three pivot members 25 extend through the first rocker arm 221 and the second rocker arm 222 along the first direction X. The connecting seat 13 of the platform 1 is rotatably connected to the first pivot member 25, the connecting rod 21 is rotatably connected to the second pivot member 25, and the first elastic member 24 is rotatably connected to the third pivot member 25.

[0058] The connecting seat 13 and the second elastic element 32 are both located between the first rocker arm 221 and the second rocker arm 222. The connecting rod 21 includes the first side portion 214, the second side portion 215 and the connecting portion 216. The first side portion 214 and the second side portion 215 are respectively located on the side of the first rocker arm 221 and the second rocker arm 222 that are far apart from each other, and are rotatably connected to the second rotating shaft 25.

[0059] For example, a plurality of second washers 28 are fitted on the second pivot member 25, and the plurality of second washers 28 are sandwiched between the first rocker arm 221 and the second rocker arm 222.

[0060] Understandably, the present invention does not specifically limit the shape and structure of the swing arm 22, as long as it can realize the rotation function between the platform 1, the connecting rod 21, and the first elastic member 24.

[0061] Furthermore, in some embodiments, the first connecting component 2 is disposed above the platform 1 to facilitate maintenance and replacement in the event of a break, thereby reducing maintenance costs and customer complaints.

[0062] Understandably, multiple first connecting components 2 can be spaced out around the platform 1, specifically around the platform plate 11, to further improve the reliability of the connection with the tower.

[0063] In some embodiments, platform 1 includes the aforementioned platform plate 11 and at least one support beam 12. The support beam 12 is connected to the platform plate 11 and provides support for the platform plate 11. At least one end of the support beam 12 is provided with the aforementioned connecting seat 13, which protrudes from the upper surface 111 of the platform plate 11. The swing arm 22 is rotatably connected to the connecting seat 13 about a first direction X. In this embodiment, the first connecting assembly 2 is directly connected to the support beam 12 via the connecting seat 13, transferring the force transmitted by the tower or other external forces to the support beam 12, reducing or even eliminating the risk of tearing the platform plate 11.

[0064] Furthermore, the direction perpendicular to the plane containing platform 1 is defined as the fourth direction H. In some cases, the fourth direction H is also the axial direction of the tower, i.e., the height direction, and the plane containing platform 1 is also the horizontal plane.

[0065] For example, the edge of platform 1 is provided with a first connecting hole penetrating along the fourth direction H, specifically, the edge of platform plate 11 is provided with a first connecting hole penetrating along the fourth direction H. That is, the first connecting hole penetrates the upper surface 111 and the lower surface 112 of platform plate 11. Support beam 12 can be fixedly connected to the lower surface 112 of platform plate 11. Both ends of support beam 12 along the second direction Y are provided with the aforementioned connecting seat 13. The connecting seat 13 protrudes from the upper surface 111 of platform plate 11 through the first connecting hole to be rotatably connected to swing rod 22. Furthermore, the aforementioned first connecting component 2 is installed on the connecting seat 13 at both ends of support beam 12.

[0066] For example, multiple support beams 12 may be provided at intervals.

[0067] For example, the support beam 12 can be an I-beam, a honeycomb beam, a flat steel, a triangular steel, etc.

[0068] Furthermore, in some embodiments, the platform structure further includes a second connecting component 3, which connects the platform 1 to the inner wall of the tower. Specifically, the first connecting component 2 and the second connecting component 3 are alternately arranged around the circumference of the platform 1, specifically around the platform plate 11.

[0069] Understandably, multiple second connection components 3 may be provided at intervals around the circumference of the platform 1, specifically around the circumference of the platform plate 11, to further improve the reliability of the connection with the tower.

[0070] Specifically, such as Figure 3 and Figure 9 As shown, the second connecting assembly 3 includes a second connecting member 31 and a second elastic member 32. The second connecting member 31 includes a second connecting portion 311, a third connecting portion 312, and a second limiting portion 313 connected in sequence. In the fourth direction H, the third connecting portion 312 penetrates the platform 1, specifically penetrating the platform plate 11. The second connecting portion 311 and the second limiting portion 313 are located on opposite sides of the platform 1. The second connecting portion 311 is used to connect to the inner wall of the tower. The second elastic member 32 is sleeved on the third connecting portion 312 and abuts against the second limiting portion 313 and the platform 1. The fourth direction H is perpendicular to the plane where the platform 1 is located. In this embodiment, the second connecting member 31 is floatingly connected to the platform 1 through the second elastic member 32. The second elastic member 32 can provide a preload force to the platform 1 to effectively suppress the tilting caused by personnel standing on the edge of the platform 1. Furthermore, when the tower sways, the second elastic element 32 can provide a certain amount of damping and clearance for the platform plate 11, so as to solve the problem of easy loosening of bolts in related technologies.

[0071] Understandably, the second elastic element 32 can be in a compressed state to provide preload to the platform plate 11.

[0072] It should be noted that the second connecting portion 311 and the third connecting portion 312 are intersecting to achieve the connection between the second connecting portion 311 and the inner wall of the tower, and the third connecting portion 312 penetrates the platform 1 in the fourth direction H. Specifically, the second connecting portion 311 can extend in a direction perpendicular to the inner wall of the tower, that is, in the aforementioned second direction Y. The third connecting portion 312 can extend along the fourth direction H. The second limiting portion 313 is connected to the end of the third connecting portion 312 that is away from the second connecting portion 311 shown.

[0073] Furthermore, in some embodiments, the edge of platform 1 is provided with a second connecting hole 113 extending along the fourth direction H. A third connecting portion 312 passes through the second connecting hole 113, and on the plane where platform 1 is located, the cross-sectional dimension of the second connecting hole 113 is larger than the cross-sectional dimension of the third connecting portion 312. In this embodiment, within the plane where platform 1 is located, the second connecting hole 113 and the second connecting member 31 provide movement space for platform 1. When the tower is horizontally operated, it operates under gravity or vibration. Through the second connecting hole 113 and the second connecting member 31, platform 1 can move relative to the tower within a certain range, thereby reducing or even eliminating the risk of rigid fracture at the connection between platform 1 and tower. In some cases, bolts are also used to connect platform 1 and tower; this arrangement can further reduce or even eliminate the risk of bolts loosening.

[0074] Understandably, the present invention does not specifically limit the shape and structure of the second connecting hole 113, as long as it allows the platform 1 to have a certain amount of movement space within its plane. For example, the second connecting hole 113 can be a large circular hole, a rectangular hole, a diamond-shaped hole, or other irregular shapes.

[0075] Furthermore, in some embodiments, along the fourth direction H, the second connecting portion 311 is located below the platform 1, and the second limiting portion 313 is located above the platform 1, with the second limiting portion 313 detachably connected to the third connecting portion 312. This configuration allows the second connecting portion 311 to support the platform 1 from below when the second limiting portion 313 is disengaged from the third connecting portion 312, preventing the platform 1 from falling and further reducing maintenance costs and customer complaints.

[0076] For example, such as Figure 9 As shown, the second elastic element 32 is a conical spring. The small diameter end of the second elastic element 32 abuts against the third connecting part 312, and the large diameter end abuts against the upper surface 111 of the platform plate 11. On the plane where the platform 1 is located, the setting size of the large diameter end is larger than the cross-sectional size of the second connecting hole 113 to prevent the second connecting part 31 and the second elastic element 32 from loosening.

[0077] For example, the second connection 311 can be connected to the inner wall of the tower by bolts, welding, snap-fit, etc., preferably by welding, which provides higher connection strength and reliability.

[0078] For example, the second connecting portion 311 includes a connecting post 3111 and a connecting piece 3112 connected together. The connecting piece 3112 is constructed as an "L"-shaped plate structure, specifically including a first plate portion and a second plate portion connected together. The first plate portion is connected to the connecting post 3111, and the second plate portion is connected to the third connecting portion 312. Specifically, on the plane of the platform 1, the size of the second plate portion is larger than the cross-sectional size of the second connecting hole 113. For example, both the connecting post 3111 and the third connecting portion 312 can be studs, and the connection between the first plate portion and the connecting post 3111, and between the second plate portion and the third connecting portion 312, can be welded, or can also be bolted, or other connection methods.

[0079] For example, the second limiting part 313 and the third connecting part 312 can be integrally formed, or they can be connected as one piece by welding, bolting, threading, snap-fitting, etc. For example, as Figure 9 As shown, the second connector 31 further includes a second fastening portion 314, the third connector 312 has a second threaded hole, and the second limiting portion 313 has a second through hole. The second fastening portion 314 passes through the second through hole of the second limiting portion 313 and connects with the second threaded hole in the third connector 312 to connect the third connector 312 and the second limiting portion 313 into one unit. For example, the second fastening portion 314 can be a bolt, and the second limiting portion 313 can be a washer.

[0080] According to an embodiment of the present invention, another aspect provides a tower, including a tower body and a platform structure of any of the above embodiments. The tower body has an inner wall, and the platform structure is disposed within the tower body and connected to the inner wall.

[0081] According to an embodiment of the present invention, in another aspect, a wind power generation device is also provided, including a platform structure as described in any of the above embodiments; or, a tower as described above.

[0082] In the tower and wind power generation equipment of the present invention, the tower and platform 1 are flexibly connected by a first connecting component 2, which solves the problem of connecting plate breakage in related technologies and improves the reliability of the connection. The tower and platform 1 are also connected by a floating first connecting component 2, which solves the problem of bolts being prone to loosening in related technologies and further improves the reliability of the connection.
