[0001] This application relates to the field of wind power equipment technology, and in particular to a support device for supporting blade reliability testing. Background Technology

[0002] my country boasts abundant wind energy resources, and in recent years, wind power technology has rapidly improved, leading to a booming industry. Blades are one of the key components of wind turbine generators, directly impacting the overall performance and cost of the unit. As a critical component of wind turbine generators, blades require various testing procedures, including static testing, fatigue testing, and modal testing, to ensure the correctness of their design, reliability, and the rationality of their manufacturing processes.

[0003] Currently, the mandatory certification test for blades is a full-size blade test, with the blade tip test arranged on the full-size blade test bench.

[0004] However, the blade experiment cannot verify the reliability of the blade tip, resulting in poor versatility of the test bench. Utility Model Content

[0005] This application provides a support device for supporting blade reliability testing, which solves the problem that the test bench cannot perform reliability testing on the blade tip, resulting in poor versatility of the test bench.

[0006] This application provides a support device for supporting blade reliability testing, the support device comprising:

[0007] foundation;

[0008] The panel assembly includes a panel and multiple mounting parts. The panel has multiple mounting holes distributed circumferentially and is used to mount blades. The multiple mounting parts connect the panel to the foundation.

[0009] The inclined beam assembly includes multiple interconnected mounting parts, which are connected to multiple mounting parts of the panel assembly, and all of them are connected to the foundation.

[0010] The number of mounting parts for the panel assembly differs from the number of mounting parts for the inclined beam assembly;

[0011] The mounting portion of the panel assembly extends vertically, while the mounting portion of the inclined beam assembly extends in an inclined direction, with the vertical and inclined directions intersecting.

[0012] In some embodiments, the number of mounting portions of the panel assembly is greater than the number of mounting portions of the inclined beam assembly.

[0013] In some embodiments, the panel assembly has three mounting portions, and the inclined beam assembly has two mounting portions, with at least a portion of the mounting portion of the inclined beam assembly connected between the two mounting portions of the panel assembly.

[0018] In two adjacent mounting sections of the panel assembly, the two first vertical plates that are close to each other are a single piece.

[0019] In some embodiments, the mounting portion of the inclined beam assembly includes:

[0020] The second horizontal plate extends horizontally, and there are multiple second horizontal plates;

[0021] The second vertical plate extends along the inclined direction, and there are two second vertical plates;

[0022] Multiple second horizontal plates are connected between two second vertical plates respectively;

[0023] In the inclined beam assembly, the second vertical plates of two adjacent mounting sections are spaced apart;

[0024] When two adjacent first vertical plates are spaced apart, a second vertical plate is connected between the two adjacent first vertical plates so that the two first vertical plates are spaced apart.

[0025] When two adjacent first vertical plates are a single piece, the second vertical plate is connected to the first vertical plate.

[0026] In some embodiments, the first horizontal plates of different mounting parts are integral pieces on the same horizontal plane.

[0027] In some embodiments, the inclined beam assembly further includes a reinforcing rib located between the second vertical plate and the first vertical plate, and extending along the horizontal direction.

[0028] In some embodiments, the number of second cross plates in the inclined beam assembly is three;

[0029] The three second horizontal plates are arranged at intervals along the extension direction of the second vertical plate.

[0030] In some embodiments, the second horizontal plate is provided with a plurality of fixing holes, which are respectively located on the periphery of the second horizontal plate, and are all used to fix the ladder.

[0031] In some embodiments, the panel and multiple mounting parts are welded together; and / or,

[0032] The inclined beam assembly is screwed to the panel assembly; and / or,

[0049] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0051] Currently, the mandatory certification test for blades is a full-size blade test. This test only covers 70% of the blade length and cannot verify the reliability of the blade tip, which poses a certain risk to the operation of the wind turbine.

[0052] To verify the blade tip strength, the blade tip test was arranged to be carried out on the full-size blade test bench, which resulted in the test occupying the full-size blade test resources and the test bench having poor versatility.

[0053] In view of this, this application provides a support device for supporting blade reliability testing. By connecting the mounting part of the panel assembly to the foundation, the panel assembly can be fixed. The mounting part of the panel assembly is connected to the panel to fix the panel. Multiple mounting holes on the panel can be used to fix the blade. Then, a diagonal beam assembly is connected to the panel assembly. This improves the support device's strength and stability to fix the blade, avoiding the impact of test accuracy due to support structure failure. Furthermore, the different numbers of mounting parts in the panel assembly and the diagonal beam assembly allow them to be assembled according to actual stress requirements, improving the adaptability of the support device to different blade test conditions, thereby increasing the versatility of the support device.

[0054] The following description, in conjunction with the accompanying drawings, describes the support device provided in the embodiments of this application for supporting blade reliability testing.

[0055] like Figure 1 and Figure 2 As shown, the support device for supporting blade reliability testing in this embodiment includes a foundation 100, a panel assembly 200, and an inclined beam assembly 300.

[0056] The panel assembly 200 includes a panel 210 and a plurality of mounting parts. The panel 210 has a plurality of mounting holes 211 arranged in a circular pattern. The panel 210 is used to mount blades. The plurality of mounting parts are connected to the panel 210 and the foundation 100.

[0057] The circumferentially distributed mounting holes 211 can adapt to the circular connection end of the blade, enabling fixation at multiple angles or circumferentially to meet the installation requirements of different test conditions. As the direct load-bearing component of the blade, the panel 210 distributes the blade load through multiple mounting holes 211, avoiding localized stress concentration. Furthermore, multiple mounting parts transfer the blade load borne by the panel 210 to the foundation 100, distributing the load to reduce the stress on individual mounting parts and improving the deformation resistance of the panel assembly 200.

[0058] The inclined beam assembly 300 includes multiple interconnected mounting parts, which are correspondingly connected to multiple mounting parts of the panel assembly 200 and all connected to the foundation 100. Through the corresponding connections of the inclined beam assembly 300 to the mounting parts of the panel assembly 200 and the connection of the inclined beam assembly 300 to the foundation 100, the inclined beam assembly 300, the panel assembly 200, and the foundation 100 form a triangular stable structure, enhancing the overall support device's anti-overturning capability and increasing its torsional resistance to sway loads. The interconnection of multiple mounting parts improves the structural stiffness of the inclined beam assembly 300 itself, preventing individual mounting parts from failing due to excessive stress.

[0059] The number of mounting parts on the panel assembly 200 differs from the number of mounting parts on the inclined beam assembly 300. This allows the number of mounting parts on both to be adjusted independently according to specific working conditions, without the need for simultaneous increases or decreases. Compared to a design with a fixed number of mounting parts, this design is more adaptable to diverse testing needs and further enhances the versatility of the support device.

[0060] The mounting portion of the panel assembly 200 extends vertically, while the mounting portion of the inclined beam assembly 300 extends in an inclined direction, intersecting the vertical and inclined directions. The vertical extension of the mounting portion of the panel assembly 200 directly transmits vertical loads to the foundation 100, reducing force dispersal and loss. The inclined extension of the mounting portion of the inclined beam assembly 300 converts lateral loads into axial forces along the direction of the inclined beam assembly, preventing excessive bending stress. The intersection of these two directions forms a three-dimensional force-bearing system that can simultaneously resist vertical and lateral loads, enhancing the overall load-bearing capacity of the device.

[0061] The support device provided in this application for supporting blade reliability testing includes a foundation 100, a panel assembly 200, and an inclined beam assembly 300. The blade is connected to the panel 210 and fixed using multiple circumferentially distributed mounting holes 211 on the panel 210. The circumferentially distributed mounting holes 211 match the blade to ensure the coaxiality of the blade installation, keeping the center of gravity of the blade consistent with the force center of the support device. The weight of the blade itself and the vertical load generated during the test first act on the panel 210. The panel 210 transmits the load to the foundation 100 through multiple mounting parts. Since the mounting parts of the panel assembly 200 extend vertically and are aligned with the direction of the vertical load, the load can be directly and efficiently transmitted to the foundation 100 along the mounting parts, reducing force decomposition and loss.

[0062] Specifically, in the experiment, simulated lateral loads such as wind and vibration are transmitted to the panel 210 through the blades. At this time, multiple mounting parts of the inclined beam assembly 300 are connected to the mounting parts of the panel assembly 200, intersecting along the inclined and vertical directions to form a triangular force-bearing structure. The lateral loads transmitted to the mounting parts of the inclined beam assembly 300 are converted into axial forces along the inclined direction and ultimately distributed to the foundation 100, preventing the panel 210 from tilting or the device from overturning due to concentrated lateral forces. The multiple mounting parts of the inclined beam assembly 300 are interconnected to form an integral rigid structure, ensuring that the lateral loads are evenly distributed within the inclined beam assembly 300 and preventing overload of any single mounting part. The panel assembly 200 and the inclined beam assembly 300 have different numbers of mounting parts, allowing them to independently bear the load according to the magnitude of the vertical and lateral loads, achieving differentiated load distribution.

[0063] It should be noted that the coordinated action of multiple mounting parts evenly distributes the load borne by the panel 210, reducing the stress intensity of individual mounting parts, avoiding structural deformation due to local overload, and ensuring the vertical load-bearing stability of the panel assembly 200. The mounting part of the inclined beam assembly 300 extends along the inclined direction and intersects with the vertical direction. Utilizing a triangular structure, it converts lateral loads into axial forces that are transmitted to the foundation 100, significantly reducing bending stress caused by lateral forces and thus enhancing the overturning resistance of the support device. The difference in the number of mounting parts between the panel assembly 200 and the inclined beam assembly 300 allows for assembly according to actual stress requirements, improving the adaptability of the support device to different blade test conditions and thereby enhancing the versatility of the support device.

[0064] In some embodiments, the panel 210 is provided with seven rings of mounting holes 211 of different diameters and circumferentially distributed to meet the installation requirements of blade tips of different sizes, and at the same time meet the requirements of multi-angle testing of blade tips.

[0065] like Figure 2 As shown, in some embodiments, the number of mounting portions of the panel assembly 200 is greater than the number of mounting portions of the inclined beam assembly 300.

[0066] In this application, after the blade is fixed to the circumferentially distributed mounting holes 211 on the panel 210, its own weight and vertical test load are first applied to the panel 210. Since the number of mounting parts in the panel assembly 200 is greater than the number of mounting parts in the inclined beam assembly 300, the vertical load borne by the panel 210 is transferred to the foundation 100 through the mounting parts. The force on the mounting parts of a single panel assembly 200 is further dispersed, effectively avoiding structural deformation caused by excessive local stress. The mounting parts of the inclined beam assembly 300 are interconnected, and the number of mounting parts in the inclined beam assembly 300 is less than the number of mounting parts in the panel assembly 200, thus evenly distributing the lateral load through overall coordination. The multiple mounting parts of the panel assembly 200 are used to disperse the vertical load.

[0067] It should be noted that the multiple mounting sections of the panel assembly 200 effectively prevent tensile or bending deformation due to overload, thereby enhancing the long-term load-bearing stability of the support device for vertical loads. The increased number of mounting sections further amplifies the vertical force transmission efficiency. The mounting sections of the inclined beam assembly 300 allow lateral loads to be transmitted through fewer paths, and combined with the axial load-bearing advantage in the inclined direction, it can reduce the dispersion loss of force during transmission. The panel assembly 200 has more mounting sections than the inclined beam assembly 300, which can adapt to static load tests of large blades. This allows the mounting sections of the panel assembly 200 to handle the continuous vertical load generated by the blade's own weight, while the fewer mounting sections of the inclined beam assembly 300 can meet the needs of intermittent lateral loads, enabling the support device to dynamically adapt to test conditions with different load proportions.

[0068] like Figure 2 As shown, in some embodiments, the panel assembly 200 has three mounting portions, the inclined beam assembly 300 has two mounting portions, and at least a portion of the mounting portions of the inclined beam assembly 300 is connected between the two mounting portions of the panel assembly 200.

[0069] In this application, the panel assembly 200 is provided with three mounting parts, which can decompose the vertical load into more paths for transmission, making the vertical load transmission more uniform. This effectively avoids bending of the mounting parts or settlement of the foundation 100 due to local overload, and significantly improves the long-term load-bearing stability of the support device under continuous vertical loads. The mounting part of the inclined beam assembly 300 connects the two mounting parts of the panel assembly 200, reducing material consumption and structural weight while ensuring lateral load-bearing capacity. Simultaneously, the inclination direction of the inclined beam converts the converged lateral force into axial force, utilizing the material's resistance to axial force to avoid bending failure, further improving the efficiency of lateral load transmission.

[0070] Furthermore, the panel assembly 200 is provided with three mounting parts and the inclined beam assembly 300 is provided with two mounting parts, which not only meets the requirement of vertical load distribution and can be adapted to the case of large blade self-weight, but also achieves efficient handling of lateral load through the inclined beam assembly 300, so that the support device can adapt to the working conditions of most blade reliability tests.

[0071] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, in some embodiments, the mounting portion of the panel assembly 200 includes a first horizontal plate 220 and a first vertical plate 230.

[0072] The first horizontal plate 220 extends horizontally, and there are multiple first horizontal plates 220. The horizontally extending first horizontal plate 220 can directly receive the horizontal component force transmitted by the panel 210 and distribute it to the first vertical plates 230 on both sides. Multiple first horizontal plates 220 can expand the horizontal force coverage area and prevent a single first horizontal plate 220 from deforming due to excessive local force.

[0073] Two first vertical plates 230 extend vertically. Multiple first horizontal plates 220 are connected between the two first vertical plates 230. The vertically extending first vertical plates 230 align with the direction of gravity, efficiently transferring vertical loads to the foundation 100. The two first vertical plates 230 are symmetrically distributed, balancing lateral forces in the horizontal direction and preventing tilting of the mounting section due to unilateral force. The multiple first horizontal plates 220 connected between the two first vertical plates 230 form a rigid frame structure, improving the overall rigidity of the mounting section of the panel assembly 200, ensuring the transmission of horizontal and vertical forces, and preventing localized failure caused by independent force on a single mounting section.

[0074] In two adjacent mounting portions of the panel assembly 200, two first vertical plates 230 are spaced apart and close to each other. This provides connection space for the mounting portions of the inclined beam assembly 300, allowing the inclined beam assembly 300 to specifically bear the lateral forces between adjacent mounting portions.

[0075] In this configuration, two adjacent first vertical plates 230 are spaced apart, and multiple first horizontal plates 220 are arranged within the spaced intervals, with each end of the multiple first horizontal plates 220 connected to two adjacent first vertical plates 230. In two adjacent mounting portions of the panel assembly 200, the first vertical plate 230 of the first mounting portion is spaced apart from the first vertical plate 230 of the other mounting portion, which can improve the structural strength of the mounting portion.

[0076] In this application, each mounting portion of the panel assembly 200 consists of multiple horizontally extending first horizontal plates 220 and two vertically extending first vertical plates 230. The multiple first horizontal plates 220 are connected between the two first vertical plates 230, forming a grid-like frame structure. When the blades transmit vertical loads through the panel 210, the load first acts on the panel 210, and then is distributed by the panel 210 to the first horizontal plates 220 of each mounting portion. The load can then be evenly transmitted laterally to the first vertical plates 230 on both sides, and finally transmitted to the foundation 100 through the vertically extending first vertical plates 230. The first vertical plates 230 are spaced apart in adjacent mounting portions, allowing each mounting portion to independently bear the lateral force component, avoiding mutual force interference caused by direct contact between adjacent first vertical plates 230. Simultaneously, the spaced areas provide buffer space for lateral forces, reducing the risk of resonance between mounting portions and further improving the overall lateral stability of the panel assembly 200.

[0077] In other embodiments, in two adjacent mounting portions of the panel assembly 200, the two adjacent first vertical plates 230 are integrally formed. The two adjacent mounting portions share a single first vertical plate 230, making one of the two first vertical plates 230 in the first mounting portion and one of the two first vertical plates 230 in the other mounting portion an integral structure. This enhances the overall rigidity of the adjacent mounting portions, creating a cooperative load-bearing structure and improving the load-bearing capacity for large-area distributed loads. Eliminating the connection gap between adjacent first vertical plates 230 avoids vibration or impact caused by gaps under lateral forces, reducing the risk of fatigue damage.

[0078] Specifically, the first vertical plate 230 of adjacent mounting parts is a single piece, eliminating the connection gaps that may exist in split structures. This allows lateral loads to be transferred between adjacent mounting parts through the continuous first vertical plate 230, avoiding vibration impacts or stress concentrations caused by gaps. When the left mounting part is subjected to a rightward lateral force, the single-piece first vertical plate 230 can transfer part of the force to the right mounting part, using the reverse load of the right mounting part to achieve internal stress balance. This suppresses relative swaying between adjacent mounting parts, reduces fatigue damage caused by resonance, and extends the service life of the support device.

[0079] like Figure 2 As shown, in some embodiments, the mounting portion of the inclined beam assembly 300 includes a second horizontal plate 310 and a second vertical plate 320. The combination of the second horizontal plate 310 and the second vertical plate 320 can both bear the lateral force transmitted by the panel 210 and efficiently transmit it to the foundation 100 along the inclined direction, forming a force support that complements the panel assembly 200.

[0080] The second horizontal plate 310 extends horizontally, and there are multiple second horizontal plates 310. The horizontal extension direction can directly receive the horizontal lateral force transmitted by the panel 210, reducing directional loss during force transmission. Multiple second horizontal plates 310 can evenly distribute the concentrated lateral force along the horizontal direction, preventing individual second horizontal plates 310 from deforming due to overload.

[0081] The second vertical plate 320 extends in an inclined direction, and there are two of them. The inclined extension direction is consistent with the direction of the axial force converted from the lateral load, which can efficiently convert the horizontal lateral force into an axial force along the second vertical plate 320 and transmit it to the foundation 100, reducing bending stress. The two second vertical plates 320 are symmetrically distributed, which can balance the torque generated by the inclined force and avoid the mounting part of the inclined beam assembly 300 from tilting on one side.

[0082] Multiple second horizontal plates 310 are respectively connected between two second vertical plates 320. This forms a rigid frame structure between the second horizontal plates 310 and the second vertical plates 320, improving the overall rigidity of the mounting part of the inclined beam assembly 300, ensuring that the horizontal component and the inclined force are transmitted in a coordinated manner between the components, and avoiding local failure caused by the independent force on a single component.

[0083] In the inclined beam assembly 300, the second vertical plates 320 of two adjacent mounting sections are spaced apart. This avoids force interference caused by direct contact between the second vertical plates 320 of the mounting sections of adjacent inclined beam assemblies 300, ensuring that each mounting section independently bears the lateral force of its corresponding area. Space is reserved for the connection between the inclined beam assembly 300 and the panel assembly 200 to avoid structural interference.

[0084] When two adjacent first vertical plates 230 are spaced apart, a second vertical plate 320 is connected between the two adjacent first vertical plates 230 to maintain the spaced arrangement. The second vertical plate 320 of the inclined beam assembly 300 is embedded within the space between the first vertical plates 230 of the panel assembly 200, directly bearing the lateral force between the first vertical plates 230 of the two panel assemblies 200, thus improving force transmission efficiency. The connection relationship fixes the spacing between the first vertical plates 230 of the panel assembly 200, preventing the spacing from shrinking or contacting due to force during testing, and maintaining the independent force-bearing characteristics of the mounting portion of the panel assembly.

[0085] When the two adjacent first vertical plates 230 are integral components, the second vertical plate 320 is correspondingly connected to the first vertical plate 230. The direct connection between the second vertical plate 320 of the inclined beam assembly and the first vertical plate 230 of the panel assembly allows for efficient transfer of lateral forces from the rigid as a whole of the panel assembly 200 to the inclined beam assembly 300, avoiding force transmission losses due to misalignment. This corresponding connection ensures that the stress points of the inclined beam assembly 300 match the rigid area of ​​the integral component of the panel assembly 200, preventing stress concentration at weak points in the panel 210.

[0086] In this application, the mounting section of the inclined beam assembly 300 consists of multiple horizontally extending second horizontal plates 310 and two inclinedly extending second vertical plates 320. The multiple second horizontal plates 310 are respectively connected between the two second vertical plates 320 to form an inclined frame structure. When the blade test generates lateral loads, the load is first transferred to the second horizontal plates 310 of the inclined beam assembly 300 through the panel assembly 200, and then transferred to the second vertical plates 320 on both sides. The inclinedly extending second vertical plates 320 convert the horizontal lateral force into an axial force along their own extension direction, efficiently transferring it to the foundation 100 and reducing the damage to the structure caused by bending stress. The second vertical plates 320 of adjacent mounting sections in the inclined beam assembly 300 are spaced apart to avoid direct contact. When lateral loads from different areas are transferred to the inclined beam assembly 300, each mounting section can independently bear the corresponding load through its own second horizontal plate 310 and second vertical plate 320 frame. The spaced design prevents the disorderly transmission of force between adjacent mounting sections, and at the same time reserves space for connection with the panel assembly 200 to ensure no structural interference.

[0087] Specifically, the connection between the inclined beam assembly 300 and the panel assembly 200 includes two implementation methods.

[0088] In the first embodiment, when the two adjacent first vertical plates 230 of the panel assembly 200 are spaced apart, the second vertical plate 320 of the inclined beam assembly 300 is embedded in and connected to the spaced area between the two first vertical plates 230. This not only directly bears the lateral force gathered in the spaced area of ​​the panel assembly 200, but also fixes the spacing between the two first vertical plates 230 through rigid connection, thus avoiding the space from shrinking or contacting due to force during the test.

[0089] In the second embodiment, the second vertical plate 320 of the inclined beam assembly 300 is connected to the first vertical plate 230 of the integral piece, so that the lateral force transmitted by the panel assembly 200 is directly introduced into the inclined beam assembly 300 through the continuous rigid first vertical plate 230. The strong rigidity of the integral piece is used to achieve efficient force transmission and avoid local stress concentration caused by connection misalignment.

[0090] In some embodiments, the first horizontal plate 220 of different mounting parts is a single piece on the same horizontal plane.

[0091] In this application, the first horizontal plate 220 of the multiple mounting portions of the panel assembly 200 is an integral structure. Compared with independent first horizontal plates 220, the integral structure eliminates the force transmission barriers between the individual first horizontal plates 220, allowing for a more uniform distribution of vertical loads. This reduces the load intensity borne by each individual mounting portion, thereby reducing the risk of deformation or damage to the first horizontal plate 220 and the first vertical plate 230 due to localized overload, further ensuring the stability of vertical load transmission. The integral first horizontal plate 220 connects different mounting portions on the same horizontal plane into a whole, enhancing the overall rigidity of the panel assembly 200. This increased overall rigidity reduces the relative displacement between the mounting portions when the panel assembly 200 is under load, resulting in a more stable structure.

[0092] like Figure 3 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, in some embodiments, the inclined beam assembly 300 further includes a reinforcing rib 330, which is located between the second vertical plate 320 and the first vertical plate 230 and extends horizontally.

[0093] In this application, a reinforcing rib 330 is provided between the first vertical plate 230 and the second vertical plate 320. The reinforcing rib 330 increases the force transmission channel, allowing the same lateral force to be transmitted simultaneously through the main path and auxiliary path, reducing the load pressure of a single path. After the reinforcing rib 330 connects the second vertical plate 320 and the first vertical plate 230, it adds rigid support between the two. The rigidity reinforcement and the overall rigidity provided by the first horizontal plate 220 of the panel assembly 200 integral component work synergistically. The overall rigidity of the panel assembly 200 ensures the uniform distribution of force, and the reinforcing rib 330 improves the local rigidity of the force transmission node, maintaining structural stability.

[0094] like Figure 2 As shown, in some embodiments, the number of second horizontal plates 310 of the inclined beam assembly 300 is three, and the three second horizontal plates 310 are arranged at intervals along the extension direction of the second vertical plate 320.

[0095] In this application, the lateral load generated by the blade test is transferred to the inclined beam assembly 300 via the panel assembly 200. Three horizontally extending second transverse plates 310 then layer the load along the inclined direction of the second vertical plate 320. Each second transverse plate 310 distributes the received force horizontally to the second vertical plates 320 on both sides, and then the inclined second vertical plates 320 convert it into axial force, which is then transferred to the foundation. Furthermore, the three second transverse plates 310, together with the second vertical plates 320 and the reinforcing ribs 330, form a three-dimensional load-bearing frame, thereby improving the structural reliability of the inclined beam assembly 300.

[0096] like Figure 2As shown, in some embodiments, the second horizontal plate 310 is provided with a plurality of fixing holes 311, which are located on the periphery of the second horizontal plate 310, and are used to fix the ladder 400.

[0097] In this application, in order to fix the ladder 400 to the inclined beam assembly 300, the connecting holes of the ladder 400 are correspondingly set with the fixing holes 311 on the second horizontal plate 310. Fastening bolts are sequentially inserted through the connecting holes on the ladder 400 and the fixing holes 311 on the second horizontal plate 310, and fastening nuts are threadedly connected to the fastening bolts, thereby fixing the ladder 400 to the inclined beam assembly 300, which facilitates personnel to climb on the inclined beam assembly 300.

[0098] In some embodiments, the panel 210 and a plurality of mounting parts are welded together.

[0099] In this application, after the blade is fixed through the mounting holes 211 of the panel 210, its own weight and vertical test load are first applied to the panel 210. Since the panel 210 and the mounting part are welded together to form a rigid whole without gaps, the load can be directly transmitted from the panel 210 to each component of the mounting part, avoiding the force transmission lag or vibration loss caused by gaps that may exist in bolted connections and other methods. The welded connection improves the reliability of the panel assembly 200 and makes the load transmitted to the inclined beam assembly 300 more stable.

[0100] like Figure 2 and Figure 3 As shown, in some embodiments, the inclined beam assembly 300 is screwed to the panel assembly 200.

[0101] In this application, the screw connection enables a detachable connection between the inclined beam assembly 300 and the panel assembly 200. During installation, the angle and position of the inclined beam assembly 300 can be adjusted using bolts to precisely align the three second horizontal plates 310 with the stress-bearing areas of the panel 210. During maintenance, damaged inclined beam components can be replaced individually without the need for complete disassembly.

[0102] like Figure 1 and Figure 2 As shown, in some embodiments, both the inclined beam assembly 300 and the panel assembly 200 are screwed to the foundation 100.

[0103] Understandably, the foundation 100 can be a T-slot platform foundation to facilitate the bolting of the panel assembly 200 and the inclined beam assembly 300.

[0104] In this application, the bolted connection between panel 210 and foundation 100, along with the integral design of the first horizontal plate 220 on the same horizontal plane, ensures that the vertical load is evenly distributed within panel assembly 200 and smoothly transferred to foundation 100 through multiple bolted nodes, preventing overload of a single node. The bolted connection between inclined beam assembly 300 and foundation 100 connects the second vertical plate 320 to the first vertical plate 230. The load is then layered into foundation 100 through the bolted nodes at the bottom of the second vertical plate 320 of inclined beam assembly 300, improving the overall structure's anti-overturning stability.
