Description

Technical Field

[0001] This invention relates to the technical field of photovoltaic product-related equipment, and in particular to a photovoltaic flexible support model with adjustable span and tilt angle. Background Technology

[0002] With the rapid development of the photovoltaic industry, flexible photovoltaic supports are increasingly widely used in complex terrains and large power plants due to their advantages such as large span, strong terrain adaptability, and relatively low cost. However, while flexible support structures are characterized by large spans, lightweight, and high flexibility, they are extremely sensitive to wind loads, exhibiting prominent wind-induced vibration and stability issues. Therefore, accurately obtaining their wind load characteristics through wind tunnel testing is crucial for structural safety design.

[0003] In existing technologies, wind tunnel stress tests on flexible photovoltaic (PV) supports typically require manual adjustment of various structural parameters, such as span spacing and PV panel tilt angle. However, this method has significant drawbacks, primarily its cumbersome procedures and difficulty in dynamically adjusting these parameters during wind tunnel operation. Consequently, in simulated wind tunnel tests, the inability to adjust according to actual needs can lead to poor wind tunnel testing results. Summary of the Invention

[0004] The purpose of this invention is to provide a photovoltaic flexible support model with adjustable span and tilt angle, so as to alleviate the technical problem in the prior art that the dynamic structure of the support cannot be adjusted in real time during wind tunnel operation, resulting in poor wind tunnel testing results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a photovoltaic flexible support model with adjustable span and tilt angle, including a driving structure, a transmission structure and multiple photovoltaic panel structures. The driving structure is connected to the transmission structure, and the driving structure is used to drive the transmission structure to move along a second direction. All of the aforementioned photovoltaic panel structures are distributed along the first direction; The transmission structure is connected to the multiple photovoltaic panel structures respectively, and the transmission structure is used to drive the multiple photovoltaic panel structures to move along the second direction in order to adjust the spacing between adjacent photovoltaic panel structures.

[0006] Furthermore, the transmission structure includes a first support block, a scissor linkage, and multiple sets of second support blocks. The first support block and the multiple sets of second support blocks are all distributed along a first direction, and the first support block is connected to the drive structure. One end of the scissor link is connected to the first support block, and the scissor link is distributed along the second direction and connected to multiple sets of the second support blocks; The first support block is used to drive the scissor link to move, so that each of the second support blocks connected to the scissor link moves along the second direction.

[0007] Furthermore, the driving structure includes a mechanism base plate and a linear guide rail, the linear guide rail being connected to the mechanism base plate along a second direction; The first support block is equipped with a slider, and the first support block is slidably connected to the linear guide rail through the slider.

[0008] Furthermore, the drive structure also includes a servo motor and an electric cylinder push rod. The servo motor is connected to the base plate of the mechanism along the second line, and the output end of the servo motor is connected to the first support block through the electric cylinder push rod.

[0009] Furthermore, the photovoltaic panel structure includes profile components, column components, and photovoltaic panel components. The profile components are distributed along a first direction, and the ends of the profile components are connected to the first support block or the second support block via connectors. The profile component is provided with the column assembly, and the column assembly is connected to the photovoltaic panel assembly, and the column assembly is used to adjust the tilt angle of the photovoltaic panel assembly.

[0010] Furthermore, the column assembly includes multiple columns and cables, the multiple columns are spaced apart along a first direction and are all connected to the profile component, and each column is connected to the photovoltaic panel assembly via the cables.

[0011] Furthermore, the plurality of columns include end columns, auxiliary columns, and middle columns, and there are two sets of end columns, which are respectively connected to the ends of the profile component; The central column is located in the middle of the two sets of end columns, and auxiliary columns are provided between the central columns and between the central columns and the end columns.

[0012] Furthermore, both the end post and the middle post include a column body and a connector, the bottom end of the column body is connected to the profile component, and the top end of the column body is rotatably connected to the connector; The connectors are respectively connected to the two sets of cables.

[0013] Furthermore, any of the columns is provided with a high-torque feedback control servo motor, the output end of which is connected to the connector to drive the connector to rotate relative to the column.

[0014] Furthermore, the end of the cable is provided with a fixing member, and the cable is connected to the profile member through the fixing member.

[0028] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Example 1 This embodiment provides a photovoltaic flexible support model with adjustable span spacing and tilt angle, referring to... Figure 1 and Figure 3 The adjustable span and tilt angle photovoltaic flexible support model includes a drive structure 1, a transmission structure 2, and multiple photovoltaic panel structures 3. The drive structure 1 is connected to the transmission structure 2, and the drive structure 1 is used to drive the transmission structure 2 to move along a second direction. The multiple photovoltaic panel structures 3 are distributed along a first direction. The transmission structure 2 is connected to the multiple photovoltaic panel structures 3 respectively, and the transmission structure 2 is used to drive the multiple photovoltaic panel structures 3 to move along the second direction to adjust the spacing between adjacent photovoltaic panel structures 3.

[0030] The embodiments of the present invention at least alleviate the technical problem in the prior art that the wind tunnel testing results are poor because the dynamic structure of the support cannot be adjusted in real time during wind tunnel operation.

[0031] In this embodiment of the invention, the drive structure 1 drives multiple sets of photovoltaic panel structures 3 to move through the transmission structure 2, thereby adjusting the spacing between the multiple sets of photovoltaic panel structures 3. For each set of photovoltaic panel structures 3, the tilt angle of the photovoltaic panel assembly 35 is adjusted through a high torque feedback control servo 322. Both the high torque feedback control servo 322 and the transmission structure 2 can be connected to an external control device. This allows the drive structure 1 and the high torque feedback control servo 322 to be controlled by the control device during wind tunnel testing, thereby adjusting the spacing between the multiple sets of photovoltaic panel structures 3 and the tilt angle of each set of photovoltaic panel assembly 35. This enables real-time adjustment of the support structure's shape during wind tunnel operation to meet the needs of wind tunnel testing.

[0032] Compared with the prior art, the photovoltaic flexible support model with adjustable span and tilt angle provided in this embodiment of the invention controls the drive structure 1 and the high torque feedback control servo motor 322 through an external control device, thereby realizing the adjustment of the spacing of multiple photovoltaic panel structures 3 and the tilt angle of each photovoltaic panel assembly 35 in wind tunnel testing, thus avoiding the technical problem of poor wind tunnel testing results.

[0033] In an optional implementation of this embodiment, refer to Figure 1 , Figure 3 and Figure 4 The transmission structure 2 includes a first support block 21, a scissor link 22, and multiple sets of second support blocks 23. The first support block 21 and the multiple sets of second support blocks 23 are distributed along a first direction, and the first support block 21 is connected to the drive structure 1. One end of the scissor link 22 is connected to the first support block 21, and the scissor link 22 is distributed along a second direction and connected to multiple sets of second support blocks 23. The first support block 21 is used to drive the scissor link 22 to move, so that each second support block 23 connected to the scissor link 22 moves along the second direction.

[0034] Specifically: the first support block 21 has a rod-shaped structure, and one end of the first support block 21 is detachably connected to the output end of the drive structure 1, and the other end of the first support block 21 is connected to a group of photovoltaic panel structures 3. One end of the scissor link 22 is connected to the middle position of the first support block 21, so that the first support block 21 can drive the scissor link 22 to extend or shorten. The scissor link 22 is provided with single-rotation connection points and double-rotation connection points at intervals, and a second support block 23 is connected at each single-rotation connection point, so that the scissor link 22 moves synchronously with the second support block 23 connected to the corresponding single-rotation connection point during the extension or shortening process.

[0035] It should be noted that the single-rotation connection point located in the middle of the scissor linkage 22 is set as a fixed connection point.

[0036] Furthermore, referring to Figure 1 and Figure 4 The drive structure 1 includes a mechanism base plate 13 and a linear guide rail 14. The linear guide rail 14 is connected to the mechanism base plate 13 along a second direction. The first support block 21 is provided with a slider 211, and the first support block 21 is slidably connected to the linear guide rail 14 through the slider 211.

[0037] Specifically: The upper surface of the base plate 13 of the mechanism is provided with linear guide rails 14, and there can be two linear guide rails 14. The two linear guide rails 14 are respectively slidably connected to the corresponding sliders 211 at the bottom of the first support block 21. Specifically, the bottom of the slider 211 is provided with a groove for sliding along the linear guide rail 14. At the same time, the linear guide rail 14 also provides stable support for the first support block 21. The second support block 23 located at the rear can also be slidably connected to the linear guide rail 14 through a sliding block.

[0038] Furthermore, referring to Figure 1 , Figure 3 and Figure 4 The drive structure 1 also includes a servo motor 11 and an electric cylinder push rod 12. The servo motor 11 is connected to the mechanism base plate 13 along the second line, and the output end of the servo motor 11 is connected to the first support block 21 through the electric cylinder push rod 12.

[0039] Specifically: The servo motor 11 is used to connect to an external control device via electrical signals, and the output end of the servo motor 11 is equipped with an electric cylinder push rod 12. The free end of the electric cylinder push rod 12 is used to detachably connect to the first support block 21 via bolts or clips. In use, the servo motor 11 is started by controlling the control device to drive the first support block 21 and the scissor linkage 22 to move via the electric cylinder push rod 12, thereby causing multiple second support blocks 23 to move together.

[0040] In an optional implementation of this embodiment, refer to Figure 1 , Figure 2 and Figure 3 The photovoltaic panel structure 3 includes a profile component 31, a column assembly, and a photovoltaic panel assembly 35. The profile component 31 is distributed along a first direction, and the end of the profile component 31 is connected to a first support block 21 or a second support block 23 through a connector. The profile component 31 is provided with a column assembly, and the column assembly is connected to the photovoltaic panel assembly 35. The column assembly is used to adjust the tilt angle of the photovoltaic panel assembly 35.

[0041] Specifically, the profile component 31 is a long structure, and multiple columns are installed at intervals on the profile component 31. Each column is connected to the photovoltaic panel module 35 via a cable 34, so that the multiple columns support the cable 34 at intervals, thereby further supporting the photovoltaic panel module 35. One end of the profile component 31 can be connected to either the first support block 21 or a second support block 23.

[0042] Furthermore, referring to Figure 1 and Figure 2 The column assembly includes multiple columns and cables 34. The multiple columns are spaced apart along the first direction and are all connected to the profile component 31. Each column is connected to the photovoltaic panel assembly 35 through the cable 34.

[0043] Specifically: multiple columns are spaced apart along the first direction, and two cables 34 are provided. The two cables 34 are symmetrically distributed and connected to each column, so that the two cables 34 are supported by multiple columns. Photovoltaic panel modules 35 are provided on the cables 34 between adjacent main bodies, so that the cables 34 are supported in segments by the spaced columns, and the photovoltaic panel modules 35 are stably supported by the cables 34.

[0044] Furthermore, referring to Figure 1 , Figure 3 and Figure 5 The plurality of columns include end columns 32, auxiliary columns 33 and middle columns 36. There are two sets of end columns 32, which are respectively connected to the ends of the profile 31. The middle column 36 is located in the middle of the two sets of end columns 32, and auxiliary columns 33 are provided between the middle columns 36 and between the middle column 36 and the end columns 32.

[0045] Specifically: There are two sets of end posts 32, and the two sets of end posts 32 are located at both ends of the profile 31. Multiple middle posts 36 are distributed at equal intervals between the two end posts 32, and multiple auxiliary posts 33 are distributed at equal intervals between adjacent middle posts 36. Through the multiple end posts 32, auxiliary posts 33 and middle posts 36, the cable 34 is kept in a horizontal state, thereby achieving the function of stably supporting the photovoltaic panel module 35.

[0046] Furthermore, referring to Figure 5 Both the end post 32 and the middle post 36 include a post body and a connector. The bottom end of the post body is connected to the profile part 31, and the top end of the post body is rotatably connected to the connector. The connector is connected to two sets of cables 34 respectively.

[0047] Specifically: the bottom of the column is connected to the profile 31 by bolts and other connecting parts, and the top of the column is rotatably connected to the connector. Both ends of the top of the connector are provided with through holes for the cable 34 to pass through. In use, by rotating the connector, a height difference is created between the two sets of cables 34 connected to it, which causes the photovoltaic panel 35 connected to the two sets of cables 34 to tilt.

[0048] Furthermore, referring to Figure 5 Each column is equipped with a high torque feedback control servo motor 322. The output end of the high torque feedback control servo motor 322 is connected to the connector to drive the connector to rotate relative to the column.

[0049] Specifically: A high-torque feedback control servo motor 322 is located at the top of the main body. This servo motor 322 is electrically connected to an external control device. The servo motor 322, through its output gear, meshes with a sector gear mounted on the end post 32 or the middle post 36, driving the end post 32 or the middle post 36 to rotate around the graphite copper sleeve shaft 321. This, in turn, causes the photovoltaic panel assembly 35 mounted on it to change its tilt angle. The tilt angle adjustment is precisely controlled by a microcontroller based on feedback signals. After adjustment, the servo motor self-locks to maintain the set tilt angle.

[0050] In an optional implementation of this embodiment, refer to Figure 2 The end of the cable 34 is provided with a fastener, and the cable 34 is connected to the profile part 31 through the fastener.

[0051] Specifically: The end of the cable 34 is provided with a fastener, which is connected to the corresponding part of the profile 31 by bolts and nuts, so that after the two ends of the cable 34 are connected, the tension of the cable 34 is determined, thereby giving the cable 34 a certain degree of support stiffness.

[0052] During operation, the servo motor 11 receives control signals and drives the electric cylinder push rod 12 to extend and retract. The linear motion of the push rod is converted into the extension and retraction of the scissor linkage 22 through the hinge point. Since the scissor linkage 22 links the two side support blocks with the middle fixed support block, it pushes all support blocks to slide along the linear guide rail. The movement of the support blocks directly drives the profile parts 31 and each column installed on them, realizing the automatic adjustment of the span of all photovoltaic panel modules.

[0053] The tilt angle of the photovoltaic panel module 35 is determined by the end column 32, the middle column 36, the graphite copper bushing 321, and the high-torque feedback control servo 322. The graphite copper bushing 321 is installed on the end column 32 or the middle column 36 to reduce rotational clearance and provide stable support. Sector gears are fixed to the sides of the end column 32 and the middle column 36. The output gear of the high-torque feedback control servo 322 meshes with the sector gear of the bracket on the end column 32 or the middle column 36, and the angle of attack of the high-torque feedback control servo 322 and the bracket is precisely controlled by an external microcontroller. After the angle of attack is adjusted, the high-torque feedback control servo 322 and the bracket self-lock, ensuring that the bracket operates precisely and stably at the set angle of attack. It should be noted that the microcontroller is a common existing device that can be electrically connected to an external control device.

[0054] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. The above embodiments in this specification are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
