Description

Technical Field

[0001] The present application relates to the field of anti-buckling technology, and in particular to an anti-buckling support device for a wind turbine cylindrical steel tower and an anti-buckling control method. Background Art

[0002] As the global demand for renewable energy continues to grow, wind power generation has been widely used as a clean energy source. Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source. Using wind power to generate electricity is very environmentally friendly and has huge wind energy reserves.

[0003] As the supporting structure of wind turbine generator sets, the stability and bearing capacity of wind turbine steel towers directly affect the safety and reliability of wind power generation systems. When subjected to complex wind loads and other external forces, traditional wind turbine steel towers are prone to local buckling and instability, which leads to a decline in structural performance and even structural damage.

[0004] In order to solve the local buckling and instability of wind turbine cylindrical steel towers, a variety of strengthening measures have been proposed, such as increasing the thickness of the tower wall, using high-strength steel, and setting internal and external annular stiffening ribs.

[0005] The technology of increasing the tower wall thickness is to increase the overall rigidity and strength of the steel tower wall by thickening it to resist external loads and wind force. However, this method significantly increases the material cost and manufacturing difficulty, and also increases the deadweight of the wind turbine cylindrical steel tower, which may cause additional burden on the tower base structure.

[0006] The technology of using high-strength steel is to use high-strength steel to manufacture wind turbine cylindrical steel towers, which can provide higher load-bearing capacity and anti-buckling performance at the same weight. However, high-strength steel is expensive, and the processing technology of this technology is complicated. Special attention needs to be paid during welding and processing to prevent the degradation of material properties.

[0007] The technology of setting inner and outer annular stiffening ribs is to set annular stiffening ribs on the inner and outer walls of the wind turbine cylindrical steel tower to enhance its bending and compression resistance. This method improves the local stability of the wind turbine cylindrical steel tower to a certain extent, but local buckling may still occur under complex wind load conditions, affecting the reliability of the wind turbine cylindrical steel tower.

[0008] Technologies such as increasing the thickness of the tower wall, using high-strength steel, and setting internal and external annular stiffening ribs can improve the bearing capacity and stability of wind turbine cylindrical steel towers to a certain extent, but they are often accompanied by high costs and complex construction problems, which are not conducive to the promotion and application of wind turbine cylindrical steel towers.

[0062] As the global demand for renewable energy continues to grow, wind power generation has been widely used as a clean energy source. As the supporting structure of wind turbines, the stability and bearing capacity of wind turbine steel towers directly affect the safety and reliability of wind power generation systems. When subjected to complex wind loads and other external forces, traditional wind turbine steel towers are prone to local buckling and instability, which leads to a decline in structural performance and even structural damage.

[0063] In order to solve the local buckling and instability of wind turbine cylindrical steel towers, a variety of strengthening measures have been proposed, such as increasing the thickness of the tower wall, using high-strength steel, and setting internal and external annular stiffening ribs. However, increasing the thickness of the tower wall, using high-strength steel, and setting internal and external annular stiffening ribs can improve the bearing capacity and stability of wind turbine cylindrical steel towers to a certain extent, but they are often accompanied by high costs and complex construction problems, which are not conducive to the promotion and application of wind turbine cylindrical steel towers.

[0064] For this purpose, see Figure 1 and Figure 2 The present application provides a novel anti-buckling support device 100 for a wind turbine cylinder-shaped steel tower. Figure 1 This is a schematic diagram of a wind turbine cylindrical steel tower anti-buckling brace device 100 according to the first embodiment of the present application. Figure 2 It is a schematic diagram of an anti-buckling brace device 100 for a wind turbine cylindrical steel tower according to another embodiment of the present application.

[0065] like Figure 3 and Figure 4 As shown, the anti-buckling support device 100 for a wind turbine cylindrical steel tower is used to provide anti-buckling support for a wind turbine cylindrical steel tower 200. Figure 3 for Figure 1 The schematic diagram of the wind turbine cylindrical steel tower anti-buckling support device 100 supporting the wind turbine cylindrical steel tower 200 is shown. Figure 4 for Figure 2 The schematic diagram shown is a wind turbine cylindrical steel tower anti-buckling support device 100 supporting a wind turbine cylindrical steel tower 200.

[0066] After the anti-buckling support device 100 of the wind turbine cylinder steel tower of the present application is used to support the wind turbine cylinder steel tower 200, the wind turbine cylinder steel tower 200 is prevented from buckling, and the reliability of the structure of the wind turbine cylinder steel tower 200 is ensured. Of course, in other embodiments of the present application, the wind turbine cylinder steel tower 200 can also support other large tower structures. The present application only takes the wind turbine cylinder steel tower anti-buckling support device 100 supporting the wind turbine cylinder steel tower 200 as an example for explanation.

[0067] It can be understood that the wind turbine cylinder steel tower 200 is generally cylindrical or conical. The wind turbine cylinder steel tower 200 has an axial direction, a circumferential direction and a radial direction. The axial direction is the height direction, the up-down direction, the top-bottom direction of the wind turbine cylinder steel tower 200, the circumferential direction is the circumferential direction of the wind turbine cylinder steel tower 200, and the radial direction is the radius direction of the wind turbine cylinder steel tower 200. The axial direction, the circumferential direction and the radial direction will not be described in detail below.

[0068] The anti-buckling support device 100 of the wind turbine tube-shaped steel tower of the present application can effectively strengthen the wind turbine tube-shaped steel tower 200 without increasing the wall thickness of the wind turbine tube-shaped steel tower 200, using high-strength steel to manufacture the wind turbine tube-shaped steel tower 200, and setting stiffening ribs in the wind turbine tube-shaped steel tower 200, etc., thereby greatly reducing the material usage, reducing the manufacturing cost and manufacturing difficulty of the wind turbine tube-shaped steel tower 200, and at the same time, being able to enhance the adaptability of the wind turbine tube-shaped steel tower anti-buckling support device 100 to various load conditions, thereby improving the reliability of the wind turbine tube-shaped steel tower 200.

[0069] Furthermore, the anti-buckling support device 100 of the wind turbine tube type steel tower of the present application supports the wind turbine tube type steel tower 200 on the inner side of the wind turbine tube type steel tower 200, that is, the anti-buckling support device 100 of the wind turbine tube type steel tower can contact the inner wall of the wind turbine tube type steel tower 200 to reliably support the wind turbine tube type steel tower 200, thereby preventing the anti-buckling support device 100 of the wind turbine tube type steel tower from being affected by external wind force, etc., and also preventing the anti-buckling support device 100 of the wind turbine tube type steel tower from being out of contact with the wind turbine tube type steel tower 200, thereby ensuring the reliability of the anti-buckling support device 100 of the wind turbine tube type steel tower in supporting the wind turbine tube type steel tower 200.

[0070] The specific structure of an anti-buckling brace device 100 for a wind turbine cylindrical steel tower according to an embodiment is described below.

[0071] See also Figures 1 to 4 In one embodiment, the anti-buckling support device 100 of the wind turbine cylindrical steel tower includes a sliding track 110, a support structure 120 and a control system 130. The sliding track 110 is circumferentially arranged around the inner wall of the wind turbine cylindrical steel tower 200. The support structure 120 is movably arranged on the sliding track 110, and the support structure 120 can contact the inner wall of the wind turbine cylindrical steel tower 200 to provide support for the wind turbine cylindrical steel tower 200.

[0072] The control system 130 is controlled and connected to the support structure 120. The control system 130 can determine the buckling position 101 of the wind turbine tube-shaped steel tower 200 according to the buckling data of the wind turbine tube-shaped steel tower 200, and control the support structure 120 to move along the sliding track 110, so that the support structure 120 abuts against the wind turbine tube-shaped steel tower 200 at the buckling position 101, and provides support for the wind turbine tube-shaped steel tower 200 to resist buckling.

[0073] The sliding track 110 is disposed around the inner wall of the wind turbine cylinder steel tower 200 along the circumference of the wind turbine cylinder steel tower 200, and the sliding track 110 is disposed protruding from the inner wall of the wind turbine cylinder steel tower 200. The support structure 120 is movably disposed on the sliding track 110, and the support structure 120 can contact the inner wall of the wind turbine cylinder steel tower 200 to prevent the wind turbine cylinder steel tower 200 from buckling in the direction of the support structure 120.

[0074] When the wind turbine cylinder steel tower 200 buckles in a certain direction, the support structure 120 can move along the sliding track 110 to the buckling position. At this time, the support structure 120 stops on the sliding track 110 and abuts against the inner wall of the wind turbine cylinder steel tower 200. In this way, when the wind turbine cylinder steel tower 200 buckles or has a tendency to buckle, the wind turbine cylinder steel tower 200 can be pressed on the support structure 120, and the support structure 120 provides support for the wind turbine cylinder steel tower 200 to prevent the wind turbine cylinder steel tower 200 from continuing to buckle.

[0075] That is to say, when the wind turbine cylinder-shaped steel tower 200 buckles or has a tendency to buckle, the support structure 120 can move to the corresponding position along the sliding track 110, and provide anti-buckling support by abutting against the inner wall of the wind turbine cylinder-shaped steel tower 200, thereby preventing the wind turbine cylinder-shaped steel tower 200 from buckling in the direction of the support structure 120, thereby ensuring the structural strength of the wind turbine cylinder-shaped steel tower 200 and improving the structural reliability of the wind turbine cylinder-shaped steel tower 200.

[0076] Furthermore, the anti-buckling support device 100 of the wind turbine cylinder steel tower of the present application determines the buckling position 101 of the wind turbine cylinder steel tower 200 through the control system 130. The buckling position 101 here refers to the position of the wind turbine cylinder steel tower 200 corresponding to the sliding track 110 along the radial direction in the buckling direction. The control system 130 is also connected to the support structure 120, and the control system 130 can control the support structure 120 to move along the sliding track 110 relative to the wind turbine cylinder steel tower 200.

[0077] Specifically, the control system 130 can obtain the buckling data of the wind turbine cylindrical steel tower 200, and the control system 130 can process the buckling data to obtain the buckling position 101 where the wind turbine cylindrical steel tower 200 is most likely to buckle under the buckling data. Subsequently, the control system 130 can control the support structure 120 to move along the sliding track 110 to the buckling position 101 and stop at the buckling position 101.

[0078] At this time, the supporting structure 120 can abut against the inner wall of the wind turbine cylinder-shaped steel tower 200 at the buckling position 101, provide support for the wind turbine cylinder-shaped steel tower 200 to resist buckling, prevent the wind turbine cylinder-shaped steel tower 200 from buckling toward the supporting structure 120, ensure the structural strength of the wind turbine cylinder-shaped steel tower 200, and improve the structural reliability of the wind turbine cylinder-shaped steel tower 200.

[0079] The anti-buckling support device 100 for the wind turbine cylindrical steel tower of the above embodiment controls the support structure 120 to move along the sliding track 110 through the control system 130, so that the support structure 120 provides support to resist buckling for the wind turbine cylindrical steel tower 200 at the corresponding buckling position 101. Moreover, when the buckling position 101 changes, the control system 130 can also control the support structure 120 to move along the sliding track 110 to the next buckling position 101, so as to effectively strengthen the wind turbine cylindrical steel tower 200 and prevent the wind turbine cylindrical steel tower 200 from buckling.

[0080] In this way, there is no need to increase the wall thickness of the wind turbine cylindrical steel tower 200, use high-strength steel materials to manufacture the wind turbine cylindrical steel tower 200, or set stiffening ribs in the wind turbine cylindrical steel tower 200, which greatly reduces the amount of materials used and reduces the manufacturing cost and difficulty of the wind turbine cylindrical steel tower 200. At the same time, by adjusting the support position of the wind turbine cylindrical steel tower 200 by the support structure 120 according to the change of the buckling data through the control system 130, the adaptability of the wind turbine cylindrical steel tower anti-buckling support device 100 to various load conditions can be enhanced, thereby improving the reliability of the wind turbine cylindrical steel tower 200.

[0081] In one embodiment, each cylinder section in the wind power cylinder steel tower 200 is connected by a flange, and the sliding track 110 can be arranged on the flange. Of course, in other embodiments of the present application, the inner wall of the wind power cylinder steel tower 200 has an annular stiffening rib, and the sliding track 110 is arranged on the stiffening rib, or the inner wall of the wind power cylinder steel tower 200 can also be provided with a protrusion, and the protrusion supports the sliding track 110, as long as the sliding track 110 and the support structure 120 are reliably supported.

[0082] See also Figure 3 and Figure 4 In one embodiment, the support structure 120 is located in the buckling region of the wind turbine cylindrical steel tower 200. Figure 3 and Figure 4 In the figure, the area where the support structure 120 is located is the area where the wind turbine cylindrical steel tower 200 is prone to buckling, that is, the buckling area. Figure 3 and Figure 4 The dotted area is shown.

[0083] After the support structure 120 is set in the buckling area, the wind turbine tube-shaped steel tower 200 generally buckles in the buckling area. At this time, the support structure 120 can support the wind turbine tube-shaped steel tower 200 in the buckling area of ​​the wind turbine tube-shaped steel tower 200 to effectively strengthen the wind turbine tube-shaped steel tower 200 and prevent the wind turbine tube-shaped steel tower 200 from buckling.

[0084] Generally, the buckling area is located at the bottom of the wind turbine cylinder steel tower 200. Of course, the buckling area can also be located at other positions of the wind turbine cylinder steel tower 200. As long as the wind turbine cylinder steel tower anti-buckling support device 100 is set in the buckling area of ​​the wind turbine cylinder steel tower 200, the wind turbine cylinder steel tower 200 can be reliably supported.

[0085] See also Figures 1 to 5 In one embodiment, along the circumference of the wind turbine cylindrical steel tower 200 , the buckling region has a plurality of buckling positions 101 , and the support structure 120 can provide support for the wind turbine cylindrical steel tower 200 at any of the buckling positions 101 . Figure 5 for Figure 3 The wind turbine cylindrical steel tower anti-buckling support device 100 is a top view schematic diagram of supporting the wind turbine cylindrical steel tower 200 at different buckling positions 101.

[0086] exist Figure 5 In the figure, four buckling positions 101 of the wind turbine cylindrical steel tower 200 are illustrated, which are a first buckling position 102, a second buckling position 103, a third buckling position 104 and a fourth buckling position 105. The first buckling position 102, the second buckling position 103, the third buckling position 104 and the fourth buckling position 105 are respectively located at a phase difference of 90° with respect to the wind turbine cylindrical steel tower 200.

[0087] When the wind turbine cylinder-shaped steel tower 200 bends from the first buckling position 102 to the third buckling position 104, the control system 130 controls the support structure 120 to move to the first buckling position 102. At this time, the support structure 120 can abut against the inner wall of the wind turbine cylinder-shaped steel tower 200 at the first buckling position 102 to prevent the wind turbine cylinder-shaped steel tower 200 from buckling from the first buckling position 102 to the third buckling position 104, thereby ensuring that the support structure 120 reliably supports the wind turbine cylinder-shaped steel tower 200.

[0088] When the wind turbine cylinder-shaped steel tower 200 bends from the second buckling position 103 to the fourth buckling position 105, the control system 130 controls the support structure 120 to move to the second buckling position 103. At this time, the support structure 120 can abut against the inner wall of the wind turbine cylinder-shaped steel tower 200 at the second buckling position 103 to prevent the wind turbine cylinder-shaped steel tower 200 from buckling from the second buckling position 103 to the fourth buckling position 105, thereby ensuring that the support structure 120 reliably supports the wind turbine cylinder-shaped steel tower 200.

[0089] When the wind turbine cylinder-shaped steel tower 200 bends from the third buckling position 104 to the first buckling position 102, the control system 130 controls the support structure 120 to move to the third buckling position 104. At this time, the support structure 120 can abut against the inner wall of the wind turbine cylinder-shaped steel tower 200 at the third buckling position 104 to prevent the wind turbine cylinder-shaped steel tower 200 from buckling from the third buckling position 104 to the first buckling position 102, thereby ensuring that the support structure 120 reliably supports the wind turbine cylinder-shaped steel tower 200.

[0090] When the wind turbine cylinder-shaped steel tower 200 bends from the fourth buckling position 105 to the second buckling position 103, the control system 130 controls the support structure 120 to move to the fourth buckling position 105. At this time, the support structure 120 can abut against the inner wall of the wind turbine cylinder-shaped steel tower 200 at the fourth buckling position 105 to prevent the wind turbine cylinder-shaped steel tower 200 from buckling from the fourth buckling position 105 to the second buckling position 103, thereby ensuring that the support structure 120 reliably supports the wind turbine cylinder-shaped steel tower 200.

[0091] It is worth noting that the buckling position 101 of the wind turbine cylindrical steel tower 200 can also be other, for example, the buckling position 101 of the wind turbine cylindrical steel tower 200 is located between the first buckling position 102 and the second buckling position 103. The principle of preventing buckling is substantially the same as the principle of preventing buckling at the above four positions, and will not be repeated in the following text.

[0092] See also Figures 1 to 4 In one embodiment, the support structure 120 includes a driving component 121 and a supporting component 122. The driving component 121 is movably disposed on the sliding track 110 and is control-connected to the control system 130. The supporting component 122 is disposed on the driving component 121, and the supporting component 122 can abut against the inner wall of the wind turbine cylindrical steel tower 200.

[0093] The driving component 121 is a power component of the supporting structure 120. The control system 130 is controlled and connected to the driving component 121. The driving component 121 is rollably arranged on the sliding track 110. When the driving component 121 rolls relative to the sliding track 110, the driving component 121 can move along the sliding track 110, and then the driving component 121 can drive the supporting component 122 to move along the sliding track 110.

[0094] The support component 122 is a component for supporting the wind power cylindrical steel tower 200. The support component 122 extends in the height direction and partially covers the wind power cylindrical steel tower 200 in the height direction. When the control system 130 controls the driving component 121 to move along the sliding track 110, the driving component 121 can drive the support component 122 to move, so that the driving component 121 drives the support component 122 to move to the buckling position 101.

[0095] At this time, the supporting component 122 can abut the inner wall of the wind turbine tube-shaped steel tower 200 at the buckling position 101, provide support for the wind turbine tube-shaped steel tower 200 to resist buckling, prevent the wind turbine tube-shaped steel tower 200 from buckling toward the supporting structure 120, ensure the structural strength of the wind turbine tube-shaped steel tower 200, and improve the structural reliability of the wind turbine tube-shaped steel tower 200.

[0096] Optionally, the support component 122 is fixed to the top of the driving component 121 by welding. Of course, in other embodiments of the present application, the support component 122 can also be reliably fixed to the top of the driving component 121 by screws or other methods.

[0097] See also Figures 1 to 4 In one embodiment, the driving component 121 includes a driving member, a vehicle body and a driving wheel 1211, the driving wheel 1211 is movably disposed on the sliding track 110, the vehicle body and the driving member are disposed on the driving wheel 1211, the driving member is control-connected to the control system 130, the supporting component 122 is disposed on the vehicle body, the driving member is connected to the driving wheel 1211, and controls the driving wheel 1211 to move along the sliding track 110.

[0098] The driving wheel 1211 is rollably located on the sliding track 110, the driving wheel 1211 rotatably supports the vehicle body, the driving member is arranged on the vehicle body, the output end of the driving member is connected to the driving wheel 1211, and the driving member is also connected to the control system 130. After the control system 130 sends a control signal to the driving member, the driving member can control the driving wheel 1211 to roll, and then the driving wheel 1211 drives the vehicle body to move along the sliding track 110 through the friction between the driving wheel 1211 and the sliding track 110.

[0099] The support component 122 is arranged on the vehicle body, and the driving wheel 1211 can drive the support component 122 to move along the sliding track 110 through the vehicle body, so that the support component 122 moves to the flexed position 101. In other words, the driving component 121 of the present application can be a driving trolley, a tractor or other structure that can realize movement along the sliding track 110 and drive the support component 122 to move. Optionally, the driving member is a motor.

[0100] See also Figures 1 to 4 In one embodiment, the support member 122 has a support surface 1221 extending along the axial direction of the wind turbine cylindrical steel tower 200. The support surface 1221 is adapted to the longitudinal section of the inner wall of the wind turbine cylindrical steel tower 200 to fit the inner wall of the wind turbine cylindrical steel tower 200 at the flexure position 101.

[0101] like Figure 1 and Figure 2 As shown, the surface of the support component 122 facing the inner wall of the wind turbine cylinder-shaped steel tower 200 is a support surface 1221, and the axial shape of the support surface 1221 is adapted to the longitudinal cross-sectional shape of the inner wall of the wind turbine cylinder-shaped steel tower 200. In this way, the support component 122 can contact the inner wall of the wind turbine cylinder-shaped steel tower 200 through the support surface 1221, thereby ensuring the supporting effect of the support component 122 on the wind turbine cylinder-shaped steel tower 200.

[0102] In this embodiment, the wind turbine cylinder-shaped steel tower 200 is cylindrical, and the inner wall of the wind turbine cylinder-shaped steel tower 200 extends in the vertical direction. Accordingly, the support surface 1221 is a vertical plane and can fit the inner wall of the wind turbine cylinder-shaped steel tower 200 to reliably support the wind turbine cylinder-shaped steel tower 200.

[0103] Of course, in other embodiments of the present application, the wind turbine tube-shaped steel tower 200 may also be configured in a conical shape, and the inner wall of the wind turbine tube-shaped steel tower 200 may be configured to be inclined. Accordingly, the support surface 1221 is an inclined surface to fit the inner wall of the wind turbine tube-shaped steel tower 200, so as to reliably support the wind turbine tube-shaped steel tower 200; or, the wind turbine tube-shaped steel tower 200 may also be other variable cross-sectional shapes, as long as the shape of the support surface 1221 is compatible with the longitudinal cross-sectional shape of the inner wall of the wind turbine tube-shaped steel tower 200, the wind turbine tube-shaped steel tower 200 can be supported.

[0104] See also Figure 1 and Figure 3 In one embodiment of the present application, the support member 122 is a stiffening rib plate. The stiffening rib plate is a reinforcing plate member that can play a reinforcing role. Figure 1 and Figure 3 In the embodiment, the stiffening rib plate includes a plurality of stiffening support plates, and the plurality of stiffening support plates are spliced ​​together to form a support component 122 of the stiffening rib plate to reliably support the wind turbine cylindrical steel tower 200 .

[0105] Optionally, the reinforcing ribs are arranged in a substantially right-angle trapezoidal shape, and the supporting surface 1221 is arranged on the surface of the reinforcing ribs facing the wind power cylindrical steel tower 200. Optionally, the reinforcing ribs are made of steel and have a certain thickness to ensure the supporting effect.

[0106] See also Figure 2 and Figure 4 In the second embodiment of the present application, the support member 122 is a lattice support. The lattice support is a bar structure formed by connecting steel sections, steel pipes or combined cross-section bars to form a frame structure. The lattice support of the frame structure reliably supports the wind turbine steel tower 200.

[0107] It is worth noting that the structures and supporting principles of the anti-buckling support devices 100 of the wind turbine cylindrical steel tower in the above two embodiments are substantially the same, except that there are differences in the structural form of the support component 122. The support component 122 of one embodiment is a stiffening rib plate, and the support component 122 of the other embodiment is a lattice support.

[0108] It can be understood that the lattice support and the stiffening rib plate support are the same except for the geometric configuration. The lattice support has a larger coverage area than the stiffening rib plate support and can provide a better support effect, but the lattice support is larger in size. In this way, the two types of support components 122 can adapt to the different sizes of buckling areas of the wind turbine cylindrical steel tower 200 to ensure the anti-buckling support effect.

[0109] When describing the structure and principle of the anti-buckling bracing device 100 for a wind turbine cylindrical steel tower, only the supporting component 122 as a stiffening rib plate is used as an example for explanation.

[0110] See also Figures 1 to 4 In one embodiment, the support structure 120 also includes a flexible contact piece 123, and the flexible contact piece 123 is arranged at the edge where the support component 122 contacts the wind turbine cylindrical steel tower 200, and the flexible contact piece 123 is used to make the support component 122 flexibly contact the inner wall of the wind turbine cylindrical steel tower 200.

[0111] The flexible contact member 123 is disposed on the support surface 1221 of the support member 122. When the support member 122 contacts the inner wall of the wind turbine cylinder steel tower 200, the support member 122 contacts the inner wall of the wind turbine cylinder steel tower 200 softly through the flexible contact member 123, thereby avoiding a hard collision between the support member 122 and the wind turbine cylinder steel tower 200 and facilitating the contact between the support member 122 and the wind turbine cylinder steel tower 200. Optionally, the flexible contact member 123 is a brush or the like.

[0112] See also Figures 1 to 4In one embodiment, the axial dimension of the support component 122 along the wind turbine cylindrical steel tower 200 is greater than or equal to the axial dimension of the buckling region of the wind turbine cylindrical steel tower 200. In other words, the axial height of the support component 122 is greater than or equal to the axial height of the buckling region, so that the support effect of the support component 122 on the wind turbine cylindrical steel tower 200 can be guaranteed.

[0113] Of course, in other embodiments of the present application, the axial dimension of the support component 122 may also be smaller than the axial dimension of the buckling area of ​​the wind turbine cylinder-shaped steel tower 200, as long as the support component 122 can reliably support the wind turbine cylinder-shaped steel tower 200.

[0114] See also Figure 1 , Figure 3 , Figure 6 and Figure 7 In one embodiment, the buckling data includes wind load data, and the anti-buckling support device 100 of the wind turbine cylindrical steel tower includes a first detection component 141, which is arranged on the top of the wind turbine cylindrical steel tower 200 and is connected to the control system 130. The first detection component 141 is used to detect the wind load data of the wind turbine cylindrical steel tower 200 and feed the wind load data back to the control system 130. Figure 6 for Figure 1 The wind turbine cylindrical steel tower anti-buckling support device 100 is shown in the working principle diagram. Figure 7 for Figure 1 Another working principle diagram of the anti-buckling brace device 100 for a wind turbine cylindrical steel tower is shown.

[0115] The first detection member 141 is disposed at the top of the wind turbine cylindrical steel tower 200 and is electrically connected to the control system 130. The first detection member 141 can detect the wind load at the top of the wind turbine cylindrical steel tower 200. When the external wind load changes, the first detection member 141 at the top of the wind turbine cylindrical steel tower 200 can detect the change in the external wind load and can feed back the wind load data to the control system 130. The control system 130 can determine the buckling position 101 of the wind turbine cylindrical steel tower 200 according to the change in wind load.

[0116] Subsequently, the control system 130 can control the driving component 121 to drive the supporting component 122 to move along the sliding track 110, so that the supporting component 122 moves to the buckling position 101. At this time, the supporting component 122 can support and reinforce the inner wall of the wind turbine tube-shaped steel tower 200 at the buckling position 101 to prevent the wind turbine tube-shaped steel tower 200 from buckling in the direction of the supporting structure 120, thereby ensuring the structural strength of the wind turbine tube-shaped steel tower 200 and improving the structural reliability of the wind turbine tube-shaped steel tower 200.

[0117] Optionally, the first detection member 141 is a wind load detection sensor. Optionally, a head is provided on the top of the wind turbine cylindrical steel tower 200, and the external wind load can also be detected through the head.

[0118] See also Figure 1 , Figure 3 , Figure 6 and Figure 7 In one embodiment, the buckling data also includes stress data, and the anti-buckling support device 100 of the wind turbine cylindrical steel tower also includes a second detection component 142. The second detection component 142 is arranged in the buckling area of ​​the wind turbine cylindrical steel tower 200 and is connected to the control system 130. The second detection component 142 is used to detect the stress data of the wind turbine cylindrical steel tower 200 in the buckling area and feed back the stress data to the control system 130.

[0119] The second detection member 142 is disposed in the buckling region of the wind turbine cylindrical steel tower 200 and is electrically connected to the control system 130. The second detection member 142 can detect stress data of the wind turbine cylindrical steel tower 200 in the buckling region. It can be understood that when the wind turbine cylindrical steel tower 200 buckles, the wind turbine cylindrical steel tower 200 will undergo stress changes in the buckling region. At this time, the second detection member 142 can detect changes in the buckling region and can feed back stress data to the control system 130.

[0120] When the control system 130 controls the support component 122 to move to the buckling position 101, the control system 130 can adjust the position of the driving component 121 according to the stress change, thereby avoiding large stress locally on the wind turbine cylindrical steel tower 200, avoiding possible buckling risks, and improving safety redundancy.

[0121] Optionally, the second detection member 142 is a stress sensor. Of course, in other embodiments of the present application, the second detection member 142 may also be other components capable of collecting stress data.

[0122] It can be understood that the present application enables the support structure 120 to support the wind turbine cylindrical steel tower 200 through the cooperation of the first detection member 141 and the second detection member 142. When the external wind load changes, the first detection member 141 feeds back the wind load data to the control system 130, and the second detection member 142 also feeds back the stress data of the wind turbine cylindrical steel tower 200 in the buckling area to the control system 130.

[0123] The control system 130 can process the wind load data and stress data to determine the buckling position 101 where the wind turbine tube-shaped steel tower 200 is most likely to buckle. Subsequently, the control system 130 can control the driving component 121 to drive the supporting component 122 to move along the sliding track 110, so that the supporting component 122 supports the wind turbine tube-shaped steel tower 200 at the buckling position 101. At the same time, the position of the supporting structure 120 is adjusted to support and reinforce the inner wall of the wind turbine tube-shaped steel tower 200.

[0124] Of course, in other embodiments of the present application, the first detection member 141 and the second detection member 142 can also be used separately. The first detection member 141 or the second detection member 142 can be used alone to detect relevant data and feed it back to the control system 130. The control system 130 outputs the flexion position 101 according to the relevant data.

[0125] See also Figure 5 In one embodiment, the wind turbine cylindrical steel tower buckling-resistance bracing device 100 further includes a connecting cable 150, and the control system 130 is electrically connected to the support structure 120 via the connecting cable 150. The control system 130 is a microcomputer, one end of the connecting cable 150 is connected to the control system 130, and the other end is connected to the driving component 121, and the control system 130 supplies power and transmits control instructions to the driving component 121 via the connecting cable 150.

[0126] Of course, in other embodiments of the present application, when there are multiple wind turbine cylindrical steel towers 200, the control system 130 is a signal station capable of transmitting control instructions, and the control system 130 transmits control instructions to the supporting structure 120 via wireless transmission.

[0127] When there are several wind turbine cylindrical steel towers 200 distributed in a certain area, a control station for transmitting command signals can be set up at the center of the area. The control system 130 of the control station is connected to each driving component 121 for communication. The control system 130 sends control instructions to the driving components 121 of each wind turbine cylindrical steel tower 200 through wireless transmission, remote control, etc., and a battery is set in the driving component 121 to supply power to the driving component 121.

[0128] See also Figures 5 to 7 In one embodiment, the control system 130 includes a processing unit, a collection unit 131, a control unit 133, and a deep learning unit based on artificial intelligence. The processing unit can obtain the historical data of the wind turbine cylindrical steel tower 200, and feed the historical data back to the deep learning unit based on artificial intelligence. The collection unit 131 is used to collect the buckling data of the wind turbine cylindrical steel tower 200, and feed the buckling data back to the deep learning unit based on artificial intelligence.

[0129] The artificial intelligence-based deep learning unit can construct a neural network model 132, and the neural network model 132 outputs the buckling position 101 of the wind turbine cylindrical steel tower 200 according to the historical data and the buckling data. The control unit 133 controls the support structure 120 to move to the buckling position 101 along the sliding track 110 according to the buckling position 101, and provides support for the wind turbine cylindrical steel tower 200 at the buckling position 101.

[0130] The processing unit is a component for collecting weather data. The processing unit can collect real-time weather data of weather forecasts, and at the same time, the processing unit can also collect historical weather data. The historical weather data here refers to the weather change data of the previous week and the data of similar weather in the same time period of different years. In this way, the control system 130 can evaluate the severity of the buckling of the wind turbine cylindrical steel tower 200 based on the real-time weather data and the historical weather data.

[0131] The collection unit 131 is connected to the first detection member 141 and the second detection member 142. The collection unit 131 can collect wind load data detected by the first detection member 141 and can also collect stress data detected by the second detection member 142. Then, the control system 130 can determine the buckling position 101 according to the wind load data and stress data collected by the collection unit 131, and can further control the movement of the support structure 120, so that the support structure 120 supports the wind turbine cylindrical steel tower 200 at the buckling position 101.

[0132] The deep learning unit based on artificial intelligence can combine artificial intelligence technology with neural networks to perform deep learning to establish a trained neural network model 132. The deep learning unit based on artificial intelligence here can use current artificial intelligence technology and combine it with current neural networks to perform deep learning to establish the neural network model 132.

[0133] Real-time weather data, historical weather data, wind load data, and stress data are processed through the neural network model 132, so that the deep learning unit based on artificial intelligence outputs corresponding control instructions, so that the control unit 133 controls the movement of the support structure 120 according to the corresponding control instructions.

[0134] Specifically, the processing unit can obtain real-time weather data according to weather forecasts and obtain historical weather data according to historical weather data. The real-time weather data and historical weather data are input into the neural network model 132, and the neural network model 132 can evaluate the impact of weather data on the wind turbine steel tower 200.

[0135] If the weather data does not affect the bending of the wind turbine cylindrical steel tower 200, the neural network model 132 sends a signal that the weather has no effect on the wind turbine cylindrical steel tower 200. At this time, the control unit 133 will not control the support structure 120 to move along the sliding track 110, and the support structure 120 will remain in the current position.

[0136] If the weather data affects the buckling of the wind turbine cylindrical steel tower 200, the neural network model 132 sends a signal of the weather impact on the wind turbine cylindrical steel tower 200. At this time, the collection unit 131 collects the wind load data on the top of the wind turbine cylindrical steel tower 200 on that day through the first detection component 141, and collects the stress data of the buckling area of ​​the wind turbine cylindrical steel tower 200 through the second detection component 142.

[0137] Subsequently, the acquisition unit 131 inputs the wind load data into the neural network model 132, which can process the wind load data and quickly predict the possible buckling position 101 of the wind turbine cylindrical steel tower 200. The control unit 133 controls the support structure 120 to move to the buckling position 101 and support the wind turbine cylindrical steel tower 200.

[0138] Then, the acquisition unit 131 inputs the stress data into the neural network model 132, and the neural network model 132 processes the stress data. According to the changes in the wind load data and the stress data, the control unit 133 adjusts the position of the supporting structure 120 to avoid large stress in the local area of ​​the wind turbine cylindrical steel tower 200, avoid possible buckling risks, and improve safety redundancy.

[0139] At the same time, when the neural network model 132 sends a signal that the weather has a serious impact on the wind turbine cylindrical steel tower 200, the control unit 133 can also issue an early warning to the management personnel of the wind turbine cylindrical steel tower 200, and the management personnel can take corresponding measures according to the early warning.

[0140] It can be understood that the neural network model 132 has pre-input the parameters and related design formulas of the wind turbine cylindrical steel tower 200, and has been trained and verified based on the weather data set wind load data and stress data. It can output early warning prompts, determine the buckling position 101 of the wind turbine cylindrical steel tower 200 where buckling is likely to occur, control the support structure 120 to move to the buckling position 101, and support and reinforce the inner wall of the wind turbine cylindrical steel tower 200 there.

[0141] The anti-buckling support device 100 of the wind turbine cylinder-shaped steel tower of the present application is provided with a sliding track 110 on the inner wall of the wind turbine cylinder-shaped steel tower 200, and a support structure 120 is provided in a specific direction. The support for the wind turbine cylinder-shaped steel tower 200 is achieved through the cooperation between the control system 130 and the support structure 120, which significantly reduces the material usage and manufacturing cost.

[0142] Moreover, the anti-buckling support device 100 of the wind turbine cylindrical steel tower can dynamically adjust the support position of the support structure 120 according to real-time and long-term load data through the first detection component 141, the second detection component 142 and the control system 130, which greatly improves the adaptability and response speed of the wind turbine cylindrical steel tower anti-buckling support device 100 to various load conditions.

[0143] Furthermore, the anti-buckling support device 100 for the wind turbine cylinder-shaped steel tower can effectively monitor and determine the buckling position 101 of the wind turbine cylinder-shaped steel tower 200 where buckling is most likely to occur, and timely adjust the support position of the support structure 120 to strengthen the buckling area of ​​the wind turbine cylinder-shaped steel tower 200, thereby greatly improving the stability and reliability of the structure of the wind turbine cylinder-shaped steel tower 200.

[0144] At the same time, the support component 122 has two structural forms, namely, the form of stiffening ribs and the form of lattice support. The stiffening ribs have less impact on the internal space of the wind power cylindrical steel tower 200, while the lattice support covers a wider area. Different forms are selected according to needs, which optimizes the internal space utilization of the wind power cylindrical steel tower 200, and is suitable for different space and coverage requirements, thereby improving the flexibility and applicability of the system.

[0145] Furthermore, the anti-buckling support device 100 for the wind turbine cylinder-shaped steel tower can independently set up a control system 130 in a single wind turbine cylinder-shaped steel tower 200, or set up multiple control stations corresponding to the wind turbine cylinder-shaped steel tower anti-buckling support devices 100 in a centralized area, and perform centralized management through remote control, thereby improving the efficiency and flexibility of the control system 130.

[0146] The anti-buckling support device 100 of the wind turbine cylinder-shaped steel tower of the present application controls the support structure 120 to move along the sliding track 110 through the control system 130, and intelligently adjusts the position of the wind turbine cylinder-shaped steel tower anti-buckling support device 100, thereby strengthening the support of the wind turbine cylinder-shaped steel tower 200 at the buckling position 101 where the wind turbine cylinder-shaped steel tower 200 is prone to buckling, greatly enhancing the adaptability of the wind turbine cylinder-shaped steel tower anti-buckling support device 100 to various load conditions and improving the reliability of the wind turbine cylinder-shaped steel tower 200 structure.

[0147] See also Figures 6 to 8 , Figure 8 This is a flow chart of an anti-buckling control method implemented in the present application. The present application also provides an anti-buckling control method, which is applied to the anti-buckling support device 100 of a wind turbine cylindrical steel tower as described in any of the above embodiments, and the anti-buckling control method comprises the following steps:

[0148] Constructing a neural network model 132 of a wind turbine cylinder steel tower 200;

[0149] Acquire the buckling data of the wind turbine cylindrical steel tower 200, and transmit the buckling data to the neural network model 132;

[0150] The buckling position 101 of the wind turbine cylindrical steel tower 200 is determined according to the neural network model 132 , and the control system 130 controls the support structure 120 to support the wind turbine cylindrical steel tower 200 on the inner side of the wind turbine cylindrical steel tower 200 .

[0151] The deep learning unit based on artificial intelligence can combine artificial intelligence technology with neural networks for deep learning to establish a trained neural network model 132. When monitoring the buckling of the wind turbine cylindrical steel tower 200, the acquisition unit 131 of the control system 130 can obtain the buckling data of the wind turbine cylindrical steel tower 200 and input the data into the neural network model 132. The buckling data is processed by the neural network model 132 to output corresponding control instructions.

[0152] Then, the control unit 133 controls the movement of the support structure 120 according to the corresponding control instructions. The control unit 133 can control the driving component 121 to drive the support component 122 to move along the sliding track 110, so that the support component 122 supports the wind power cylinder steel tower 200 at the buckling position 101, and at the same time, adjusts the position of the support structure 120 to support and reinforce the inner wall of the wind power cylinder steel tower 200.

[0153] In one embodiment, before obtaining the buckling data of the wind turbine cylindrical steel tower 200, the anti-buckling control method further includes the following steps:

[0154] Get real-time weather data based on weather forecasts and get historical weather data;

[0155] Input the real-time weather data and the historical weather data into the neural network model 132, evaluate the severity of the weather's impact on the wind turbine cylindrical steel tower 200, and determine whether it is necessary to start the wind turbine cylindrical steel tower anti-buckling support device 100;

[0156] When the impact is serious, the neural network model 132 issues an alarm prompt;

[0157] And / or, the step of obtaining the buckling data of the wind turbine cylindrical steel tower 200 comprises the following steps:

[0158] Acquire wind load data of the wind turbine cylindrical steel tower 200, and input the wind load data into the neural network model 132, the neural network model 132 outputs the buckling position 101, and the control system 130 controls the support structure 120 to move to the buckling position 101;

[0159] The stress data of the wind turbine cylindrical steel tower 200 is obtained, and the wind load data and the stress data are input into the neural network model 132. The control system 130 adjusts the position of the support structure 120 according to the changes of the wind load data and the stress data.

[0160] The processing unit can obtain real-time weather data according to weather forecasts and obtain historical weather data according to historical weather data. The real-time weather data and historical weather data are input into the neural network model 132, and the neural network model 132 can evaluate the impact of weather data on the wind turbine steel tower 200.

[0161] If the weather data does not affect the bending of the wind turbine cylindrical steel tower 200, the neural network model 132 sends a signal that the weather has no effect on the wind turbine cylindrical steel tower 200. At this time, the control unit 133 will not control the support structure 120 to move along the sliding track 110, and the support structure 120 will remain in the current position.

[0162] If the weather data affects the buckling of the wind turbine cylindrical steel tower 200, the neural network model 132 sends a signal of the weather impact on the wind turbine cylindrical steel tower 200. At this time, the collection unit 131 collects the wind load data on the top of the wind turbine cylindrical steel tower 200 on that day through the first detection component 141, and collects the stress data of the buckling area of ​​the wind turbine cylindrical steel tower 200 through the second detection component 142.

[0163] Subsequently, the acquisition unit 131 inputs the wind load data into the neural network model 132, which can process the wind load data and quickly predict the possible buckling position 101 of the wind turbine cylindrical steel tower 200. The control unit 133 controls the support structure 120 to move to the buckling position 101 and support the wind turbine cylindrical steel tower 200.

[0164] Then, the acquisition unit 131 inputs the stress data into the neural network model 132, and the neural network model 132 processes the stress data. According to the changes in the wind load data and the stress data, the control unit 133 adjusts the position of the supporting structure 120 to avoid large stress in the local area of ​​the wind turbine cylindrical steel tower 200, avoid possible buckling risks, and improve safety redundancy.

[0165] At the same time, when the neural network model 132 sends a signal that the weather has a serious impact on the wind turbine cylindrical steel tower 200, the control unit 133 can also issue an early warning to the management personnel of the wind turbine cylindrical steel tower 200, and the management personnel can take corresponding measures according to the early warning.

[0166] It can be understood that the neural network model 132 has pre-input the parameters and related design formulas of the wind turbine cylindrical steel tower 200, and has been trained and verified based on the weather data set wind load data and stress data. It can output early warning prompts, determine the buckling position 101 of the wind turbine cylindrical steel tower 200 where buckling is likely to occur, control the support structure 120 to move to the buckling position 101, and support and reinforce the inner wall of the wind turbine cylindrical steel tower 200 there.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
