[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] Combine the following Figures 1 to 9 , describing an embodiment of the present invention.

[0032] According to an embodiment of the present invention, on the one hand, a platform structure is provided, wherein the platform structure is arranged in a tower (not shown in the figure), and the tower has a tower inner wall. Figure 1-Figure 3 As shown, the platform structure includes a platform 1 and a first connecting component 2, and the first connecting component 2 is connected between the platform 1 and the inner wall of the tower.

[0033] Specifically, combined Figure 4-Figure 6, the first connecting assembly 2 includes a swing rod 22, a connecting rod 21 and a first connecting member 23. Among them, one end of the swing rod 22 is rotatably connected to the platform 1 around the first direction X. The connecting rod 21 is rotatably connected to the end of the swing rod 22 away from the platform 1 around the first direction X. That is, the two ends of the swing rod 22 are rotatably connected to the platform 1 and the connecting rod 21 respectively. An activity space 213 is formed in the connecting rod 21, which runs through the second direction Y. One end of the first connecting member 23 is movably connected to the activity space 213, and the other end is used to connect to the inner wall of the tower. Among them, the second direction Y is perpendicular to the inner wall of the tower, and the first direction X intersects with the second direction Y. In some cases, the first direction X can be perpendicular to the second direction Y.

[0034] In this embodiment, the platform 1 forms a four-link 21 structure with the inner wall of the tower through the connecting rod 21, the swing rod 22, the first connecting member 23, so that when the tower shakes, the platform 1 can swing with the tower within a certain amplitude to play a buffering role and resist the damage of the tower shaking to the connection between the inner wall of the tower and the platform 1. That is, the inner wall of the tower and the platform 1 of the present invention adopt a flexible connection method, which solves the pain point problem of the connection plate breaking in the related art and improves the reliability of the connection between the two.

[0035] It can be understood that 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 some cases, the first direction X can be perpendicular to the second direction Y, and the first direction X is also the circumferential direction of the tower or a tangent direction tangent to the circumferential direction of the tower.

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

[0037] Specifically, the platform plate 11 includes an upper surface 111 and a lower surface 112 that are oppositely disposed, and an outer side surface 114 connected between the upper surface 111 and the lower surface 112. The circumferential direction of the platform plate 11 is also the extending direction of the outer side surface 114 of the platform plate 11.

[0038] It is understandable that 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. Exemplarily, the platform plate 11 can also be a rectangular plate structure, a polygonal plate structure or other irregular plate structures.

[0039] Specifically, in some embodiments, the first connecting member 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 arranged in the activity space 213. The first limiting portion 232 is located outside the activity space 213, and is used to limit the first connecting portion 231 from being separated from the activity space 213. Along the third direction Z, the cross-sectional dimension of the activity space 213 is greater than the cross-sectional dimension of the first connecting portion 231. Among them, the third direction Z and the second direction Y are perpendicular to each other. In this embodiment, the cross-sectional dimension of the activity space 213 is greater than the cross-sectional dimension of the first connecting portion 231, and the activity space 213 can provide the first connecting portion 231 with degrees of freedom in all directions, so that the first connecting member 23 can move relative to the connecting rod 21 with the shaking of the tower, so as to play a buffering role, and further improve the reliability of the connection between the platform 1 and the tower.

[0040] It can be understood that the present invention does not specifically limit the shape and structure of the first connection part 231, as long as it can be inserted into the activity space 213 and movably connected with the connecting rod 21. Exemplarily, the first connection part 231 can be configured as a cylinder, a rod, a prism, a block or other irregular shapes, as long as the cross-sectional size of the activity space 213 along the third direction Z is greater than the cross-sectional size of the first connection part 231. Exemplarily, the first connection part 231 is cylindrical. In this case, on the cross section along the third direction Z, the size of the activity space 213 in any direction should be greater than the diameter of the first connection part 231.

[0041] Exemplarily, the first connection portion 231 and the inner wall of the tower may be connected by bolts, welding, clamping, etc., preferably welding, which has higher connection strength and reliability.

[0042] Exemplarily, the connecting rod 21 has a first side surface 211 and a second side surface 212 that are arranged opposite to each other along the second direction Y, the first side surface 211 is close to the inner wall of the tower, the second side surface 212 is far from the inner wall of the tower, and the activity space 213 runs through the first side surface 211 and the second side surface 212. The activity space 213 forms an opening on the second side surface 212, and the setting size of the second limiting portion 313 is larger than the setting size of the opening, so as to limit the first connecting portion 231 from being separated from the activity space 213.

[0043] It is understandable that the present invention does not specifically limit the shape and structure of the second limiting portion 313 and the connection method between the second limiting portion 313 and the first connecting portion 231 , as long as the function of limiting the first connecting portion 231 from leaving the activity space 213 can be achieved.

[0044] Exemplarily, the second limiting portion 313 may be configured 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. Exemplarily, the second limiting portion 313 may be configured as a rectangular plate-like 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 portion 232 and the first connecting portion 231 may be integrally formed, or may be connected as a whole by welding, bolt connection, thread connection, clamping, etc. For example, Figure 5 and Figure 7 As shown, the first connecting member 23 further includes a first fastening portion 233. Along the second direction Y, a first threaded hole is provided in the first connecting portion 231, and a first through hole is provided on the first limiting portion 232. The first fastening portion 233 is penetrated in the first through hole of the first limiting portion 232 and connected with the first threaded hole in the first connecting portion 231, so as to connect the first connecting portion 231 and the first limiting portion 232 as a whole. Exemplarily, the first fastening portion 233 may be a bolt, and the first limiting portion 232 may be a gasket.

[0046] Furthermore, in some embodiments, 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, wherein the first side portion 214 and the second side portion 215 are arranged at intervals along the first direction X, and the connecting portion 216 is connected between the first side portion 214 and the second side portion 215 to form a "U"-shaped structure together. Among them, one end of the first side portion 214 and the second side portion 215 away from the connecting portion 216 is respectively rotatably connected to the two 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 above-mentioned activity space 213. Exemplarily, the connecting portion 216 can be configured as a circle, and the first connecting portion 231 can be configured 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 member 24, one end of the first elastic member 24 is rotatably connected to the middle of the swing rod 22 around the first direction X, and the other end is connected to the inner wall of the tower. It can be understood that the first elastic member 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 shakes, part of the force can be converted into the elastic potential energy of the first elastic member 24 to play a buffering role, avoid rigid fracture at the connection between the platform 1 and the inner wall of the tower, and further improve the reliability of the connection between the platform 1 and the tower.

[0048] For example, Figure 5 and Figure 7 As shown, the first elastic member 24 includes a fourth connection portion 241, an elastic portion 243 and a fifth connection portion 242 connected in sequence, wherein one end of the fourth connection portion 241 is rotatably connected to the swing rod 22 around the first direction X, and the other end is fixedly connected to the elastic portion 243, and one end of the fifth connection portion 242 is connected to the elastic portion 243, and the other end is connected to the inner wall of the tower. The fourth connection portion 241 is provided to improve the reliability of the rotational connection between the second elastic member 32 and the swing rod 22, and the fifth connection portion 242 is provided to improve the connection strength between the second elastic member 32 and the inner wall of the tower.

[0049] Exemplarily, the fifth connection portion 242 and the inner wall of the tower may be connected by bolts, welding, clamping, etc., preferably by welding, which has higher connection strength and reliability.

[0050] Exemplarily, the ends of the fourth connecting portion 241 and the fifth connecting portion 242 facing the elastic portion 243 may be provided with a groove, and the two ends of the elastic portion 243 are embedded in the groove and fixedly connected to the inner wall of the groove. Exemplarily, the ends of the fourth connecting portion 241 and the fifth connecting portion 242 facing the elastic portion 243 may be provided with a boss, and the two ends of the elastic portion 243 are sleeved outside the boss and fixedly connected to the outer wall of the boss. Exemplarily, one of the ends of the fourth connecting portion 241 and the fifth connecting portion 242 facing the elastic portion 243 is provided with a groove, and the other is provided with a boss, one end of the elastic portion 243 is embedded in the groove and fixedly connected to the inner wall of the groove, and the other end is sleeved outside the boss and fixedly connected to the outer wall of the boss.

[0051] Exemplarily, an end of the fourth connection part 241 away from the elastic part 243 can be provided with a connecting ear plate to facilitate rotational connection with the rocker arm 22; an end face of the fifth connection part 242 away from the elastic part 243 can have a flat surface or a curved surface to facilitate adhesion and connection with the inner wall of the tower.

[0052] Exemplarily, the elastic part 243 may be a spring. Exemplarily, the elastic part 243 may be in a compressed state.

[0053] It can be understood that the platform 1 and the swing rod 22 , the connecting rod 21 and the swing rod 22 , and the second elastic portion 243 and the swing rod 22 are all rotationally connected via the rotating shaft 25 .

[0054] Exemplarily, three rotating shaft members 25 may be provided, and the first rotating shaft member 25 penetrates the swing rod 22 and the connecting seat 13 on the platform 1 along the first direction X, so that the swing rod 22 can rotate relative to the platform 1 around the first direction X. The second rotating shaft member 25 penetrates the swing rod 22 and the connecting rod 21 along the first direction X, so that the swing rod 22 and the connecting rod 21 can rotate relative to each other around the first direction X. The third rotating shaft member 25 penetrates the swing rod 22 and the fourth connecting portion 241 of the second elastic member 32 along the first direction X, so that the swing rod 22 and the second elastic member 32 can rotate relative to each other around the first direction X.

[0055] Exemplarily, the rotating shaft 25 includes a rotating shaft portion and end portions connected to both ends of the rotating shaft portion. First gaskets 26 may be provided on both sides of the swing rod 22 , and the first gasket 26 is sandwiched between the swing rod 22 and the end portions.

[0056] For example, the shaft portion and the end portion of the shaft member 25 may be threadedly connected, and the three shaft members 25 may be sleeved with a sleeve 27 (eg, Figure 8 As shown in the figure, the connecting seat 13, the connecting rod 21 and the second elastic member 32 are all sleeved outside the shaft sleeve 27 to reduce or even eliminate the risk of the rotating shaft portion and the end portion being loosened.

[0057] In some embodiments, the swing rod 22 includes a first swing rod 221 and a second swing rod 222 spaced apart along the first direction X, and the first swing rod 221 and the second swing rod 222 are both configured as plate-like structures. The three rotating shaft members 25 all penetrate the first swing rod 221 and the second swing rod 222 along the first direction X. The connecting seat 13 of the platform 1 is rotatably connected to the first rotating shaft member 25, the connecting rod 21 is rotatably connected to the second rotating shaft member 25, and the first elastic member 24 is rotatably connected to the third rotating shaft member 25.

[0058] The connecting seat 13 and the second elastic member 32 are both located between the first swing rod 221 and the second swing rod 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 away from the first swing rod 221 and the second swing rod 222, and are rotatably connected to the second rotating shaft member 25.

[0059] Exemplarily, a plurality of second gaskets 28 are sleeved on the second rotating shaft 25 , and the plurality of second gaskets 28 are sandwiched between the first swing rod 221 and the second swing rod 222 .

[0060] It can be understood that the present invention does not impose any specific limitation on the shape and structure of the swing rod 22 , as long as the swing rod 22 can be rotated among 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 when a break occurs, thereby reducing maintenance costs and customer complaints.

[0062] It can be understood that a plurality of first connection assemblies 2 can be arranged 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.

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

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

[0065] Exemplarily, the edge of the platform 1 is provided with a first connection hole penetrating along the fourth direction H, specifically, the edge of the platform plate 11 is provided with a first connection hole penetrating along the fourth direction H. That is, the first connection hole penetrates the upper surface 111 and the lower surface 112 of the platform plate 11. The support beam 12 can be fixedly connected to the lower surface 112 of the platform plate 11, and the support beam 12 is provided with the above-mentioned connection seat 13 at both ends along the second direction Y. The connection seat 13 protrudes from the upper surface 111 of the platform plate 11 through the first connection hole to be rotatably connected with the swing rod 22. In addition, the above-mentioned first connection assembly 2 is installed on the connection seats 13 at both ends of the support beam 12.

[0066] For example, a plurality of support beams 12 may be arranged at intervals.

[0067] Exemplarily, the support beam 12 may be an I-beam, a honeycomb beam, a flat steel, a triangular steel, or the like.

[0068] Further, in some embodiments, the platform structure further includes a second connection assembly 3, which is connected between the platform 1 and the inner wall of the tower. The first connection assembly 2 and the second connection assembly 3 are alternately arranged around the circumference of the platform 1, specifically around the circumference of the platform plate 11.

[0069] It can be understood that a plurality of second connection assemblies 3 may be arranged 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, Figure 3 and Fig. 9 As shown, the second connection assembly 3 includes a second connection member 31 and a second elastic member 32. The second connection member 31 includes a second connection portion 311, a third connection portion 312 and a second limit portion 313 connected in sequence. In the fourth direction H, the third connection portion 312 passes through the platform 1, specifically, passes through the platform plate 11, and the second connection portion 311 and the second limit portion 313 are respectively located on both sides of the platform 1. The second connection portion 311 is used to connect with the inner wall of the tower. The second elastic member 32 is sleeved on the third connection portion 312 and abuts between the second limit portion 313 and the platform 1. Among them, the fourth direction H is perpendicular to the plane where the platform 1 is located. In this embodiment, the second connection member 31 is floatingly connected to the platform 1 through the second elastic member 32, and the second elastic member 32 can provide a pre-tightening force for the platform 1 to effectively suppress the occurrence of a tilting situation caused by a person standing on the edge of the platform 1. Furthermore, when the tower shakes, the second elastic member 32 can provide a certain amount of damping and clearance for the platform plate 11, so as to solve the pain point problem that the bolts are easy to loosen in the related art.

[0071] It can be understood that the second elastic member 32 can be in a compressed state to provide a pre-tightening force for the platform plate 11 .

[0072] It should be noted that the second connection portion 311 and the third connection portion 312 are arranged to intersect so as to realize the connection between the second connection portion 311 and the inner wall of the tower, and the third connection portion 312 penetrates the platform 1 in the fourth direction H. Specifically, the second connection portion 311 may extend in a direction perpendicular to the inner wall of the tower, that is, the second direction Y. The third connection portion 312 may extend along the fourth direction H. The second limiting portion 313 is connected to an end of the third connection portion 312 away from the second connection portion 311.

[0073] Further, in some embodiments, the edge of the platform 1 is provided with a second connection hole 113 penetrating along the fourth direction H. The third connection portion 312 is inserted into the second connection hole 113, and on the plane where the platform 1 is located, the cross-sectional size of the second connection hole 113 is larger than the cross-sectional size of the third connection portion 312. In this embodiment, in the plane where the platform 1 is located, the second connection hole 113 and the second connection member 31 provide a moving space for the platform 1. When the tower is in horizontal operation, it is subjected to gravity or vibration. Through the second connection hole 113 and the second connection member 31, the platform 1 can move relative to the tower within a certain range, so as to reduce or even eliminate the risk of rigid fracture at the connection between the platform 1 and the tower. In some cases, bolts are also connected between the platform 1 and the tower. Such a configuration can also reduce or even eliminate the risk of loosening of the bolts.

[0074] It is understandable that the present invention does not specifically limit the shape of the second connection hole 113, as long as the platform 1 is allowed to have a certain movement space in the plane. For example, the second connection hole 113 can be a large circular hole, a rectangular hole, a diamond hole or other irregular shapes.

[0075] Further, in some embodiments, along the fourth direction H, the second connection portion 311 is located below the platform 1, the second limit portion 313 is located above the platform 1, and the second limit portion 313 is detachably connected to the third connection portion 312. In this way, when the second limit portion 313 is separated from the third connection portion 312, the second connection portion 311 can receive the platform 1 below to prevent the platform 1 from falling, thereby further reducing operation and maintenance costs and customer complaints.

[0076] For example, Fig. 9 As shown, the second elastic member 32 is a conical spring, the small diameter end of the second elastic member 32 abuts against the third connecting portion 312, and the large diameter end abuts against the upper surface 111 of the platform plate 11, and 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 member 31 and the second elastic member 32 from loosening.

[0077] Exemplarily, the second connection portion 311 and the inner wall of the tower can be connected by bolts, welding, clamping, etc., preferably welding, which has higher connection strength and reliability.

[0078] Exemplarily, the second connection part 311 includes a connection column 3111 and a connection piece 3112 connected to each other, and the connection piece 3112 is constructed as an "L"-shaped plate structure, specifically including a first plate part and a second plate part connected to each other, the first plate part is connected to the connection column 3111, and the second plate part is connected to the third connection part 312. Among them, on the plane where the platform 1 is located, the setting size of the second plate part is larger than the cross-sectional size of the second connection hole 113. Exemplarily, the connection column 3111 and the third connection part 312 can both be studs, and the first plate part and the connection column 3111, and the second plate part and the third connection part 312 can both be welded, and of course they can also be bolted, or connected in other connection methods.

[0079] For example, the second limiting portion 313 and the third connecting portion 312 may be integrally formed, or may be connected as a whole by welding, bolt connection, thread connection, clamping, etc. For example, Fig. 9 As shown, the second connecting member 31 further includes a second fastening portion 314, a second threaded hole is provided in the third connecting portion 312, and a second through hole is provided on the second limiting portion 313, the second fastening portion 314 is penetrated in the second through hole of the second limiting portion 313, and connected with the second threaded hole in the third connecting portion 312, so as to integrally connect the third connecting portion 312 and the second limiting portion 313. Exemplarily, the second fastening portion 314 may be a bolt, and the second limiting portion 313 may be a gasket.

[0080] According to an embodiment of the present invention, on the other hand, a tower is provided, comprising a tower body and a platform structure of any of the above embodiments, wherein the tower body has a tower inner wall, and the platform structure is arranged in the tower body and connected to the tower inner wall.

[0081] According to an embodiment of the present invention, in another aspect, a wind power generation device is provided, comprising a platform structure as described in any one 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 the platform 1 are flexibly connected by the first connecting assembly 2, which solves the pain point problem of the connection plate breaking in the related art and improves the reliability of the connection. The tower and the platform 1 are floatingly connected by the first connecting assembly 2, which solves the pain point problem of the bolts being easy to loose in the related art and further improves the reliability of the connection.

[0083] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
