Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and more specifically, to an adjustable fixed photovoltaic support and a photovoltaic power generation system. Background Technology

[0002] With the continued growth of global energy demand, countries are placing increasing emphasis on the development of renewable energy. Photovoltaic power generation, as an important form of clean energy, has received growing attention and investment. Photovoltaic support systems, as a crucial component of photovoltaic power generation systems, play a vital role in the efficiency and stability of photovoltaic power generation. An efficient and stable photovoltaic support system can significantly improve the overall performance of a photovoltaic power generation system.

[0003] Traditional fixed photovoltaic (PV) mounting systems offer good stability, are material-efficient, and easy to install, but their photoelectric conversion efficiency is relatively low. Tracking mounting systems, while having high photoelectric conversion efficiency, are complex in structure and expensive. Adjustable fixed PV mounting systems combine the advantages of both. Their structure simplifies azimuth tracking, allowing manual operation to track the sun's noon altitude angle and adjust the angle according to seasonal changes. This structure simplifies the mounting system, reduces costs, and improves photoelectric conversion efficiency compared to fixed mounting systems. This gives fixed adjustable mounting systems a unique competitive advantage in the PV power generation market and a promising future. However, current tilt adjustment methods mainly include: 1. push-pull type; 2. semi-circular arc type; 3. jack type. These are complex in structure and require multiple operators for adjustment, making them inconvenient. Utility Model Content

[0048] Figure 1 This is a schematic diagram of the structure of the photovoltaic power generation system 20 provided in this embodiment. Figure 2 This is a schematic diagram of the drive unit in the adjustable fixed photovoltaic bracket 10 provided in this embodiment. Figure 3 This is a structural schematic diagram of the driven part in the adjustable fixed photovoltaic bracket provided in this embodiment. Please refer to the reference diagram. Figures 1-3 This embodiment provides an adjustable fixed photovoltaic bracket 10, and also provides a photovoltaic power generation system 20.

[0049] The photovoltaic power generation system 20 includes an adjustable fixed photovoltaic support 10 and photovoltaic modules 23. The photovoltaic modules 23 are mounted on the main beam 110 of the fixed photovoltaic support 10, allowing them to rotate with the main beam 110 to adjust their angle and track the noon solar altitude angle. Specifically, the photovoltaic power generation system 20 also includes purlins 21 and brackets 22. The brackets 22 are fixedly mounted on the main beam 110, the purlins 21 are fixedly mounted on the brackets 22, and the photovoltaic modules 23 are fixedly mounted on the purlins 21, which support the photovoltaic modules 23. It should be noted that the structure of the adjustable fixed photovoltaic support 10 is illustrated for clarity. Figure 1Some photovoltaic modules 23 have been removed, with only one remaining for illustration.

[0050] The adjustable fixed photovoltaic support 10 includes a main beam 110 and a plurality of columns 120 that support the main beam 110. Each column 120 is connected to the main beam 110 through a bearing arc assembly 200, thereby enabling the column 120 to rotatably support the main beam 110 through the bearing arc assembly 200.

[0051] Optionally, a push rod structure 400 is provided between one of the columns 120 and the main beam 110. The push rod structure 400 is telescopic, allowing the main beam 110 to rotate relative to the column 120 by extending or retracting, thereby adjusting the tilt angle of the photovoltaic module. Simultaneously, when the push rod structure 400 is not extended or retracted, it supports the main beam 110, keeping it in a fixed state. This adjustable fixed photovoltaic bracket 10 drives the main beam 110 to rotate relative to the column 120 via the push rod structure 400. Specifically, the connection between the column 120 and the main beam 110 is the driving part, and the column 120 connected to the push rod structure 400 and forming the driving part is the first column 122. The connections between the remaining columns 120 and the main beam 110 do not require push rod structures 400; these connections without push rod structures 400 are the driven parts. When the push rod structure 400 in the driving part pushes the main beam 110 to rotate, the driven parts of the main beam 110 also rotate accordingly.

[0052] The adjustable fixed photovoltaic bracket 10 achieves angle adjustment through the extension and retraction of the push rod structure 400. The structure is simple and the adjustment is convenient, which helps to realize single-person operation and adjustment.

[0053] The structure of the adjustable fixed photovoltaic bracket 10 provided in this embodiment will be further described below:

[0054] Figure 4 This is a schematic diagram of the bearing arc assembly 200 in the adjustable fixed photovoltaic bracket 10 provided in this embodiment. Figure 5 This is a schematic diagram of the drive plate 230 in the adjustable fixed photovoltaic bracket 10 provided in this embodiment. Please refer to the diagram. Figures 1-5 In this embodiment, the bearing arc assembly 200 includes a first rotating connector 210 and a second rotating connector 220, which are rotatably connected. The first rotating connector 210 includes a clamp 211 with a mounting groove 212 adapted to the shape of the main beam 110. The main beam 110 is mounted in the mounting groove 212, thereby fixing the main beam 110 relative to the first rotating connector 210. The second rotating connector 220 is fixedly connected to the column 120, thereby achieving a rotatable connection with the main beam 110.

[0055] Specifically, in this embodiment, the main beam 110 is a tubular component with a rectangular cross-section, and correspondingly, the mounting groove 212 is rectangular. The clamp 211 is a structure with a rectangular recess formed by bending sheet metal. After the main beam 110 is installed in the mounting groove 212, it rotates synchronously with the clamp 211.

[0056] Furthermore, the mounting groove 212 has an upper opening, and the bearing arc assembly 200 also includes a drive pressure plate 230. The drive pressure plate 230 is fixedly mounted on the clamp 211 and is used to close the upper opening. Thus, the drive pressure plate 230 and the mounting groove 212 of the clamp 211 form a circumferentially closed mounting space, in which the main beam 110 is confined, thereby fixing the main beam 110 within the mounting groove 212.

[0057] Optionally, the driving pressure plate 230 has first connecting holes 231 at both ends, and the clamping member 211 has second connecting holes 217 at both ends. The driving pressure plate 230 is fixedly connected to the clamping member 211 by connecting bolts that cooperate with the first connecting holes 231 and the second connecting holes 217.

[0058] Specifically, the driving pressure plate 230 is a rectangular plate with first connecting holes 231 at both ends along its length. The clamping member 211 has connecting parts on both sides of the mounting groove 212, and the connecting parts have second connecting holes 217. The two ends of the first connecting holes 231 on the driving pressure plate 230 overlap with the two connecting parts, so that the first connecting holes 231 and the second connecting holes 217 are aligned. The connecting bolts pass through the first connecting holes 231 and the second connecting holes 217 and are locked, thereby fixing the driving pressure plate 230 to the clamping member 211.

[0059] Furthermore, the drive pressure plate 230 is also provided with a reinforcing protrusion extending from one end to the other, thereby strengthening the drive pressure plate 230 and preventing deformation when the push rod structure 400 pushes the main beam 110 to rotate. Specifically, the drive pressure plate 230 has upwardly bent protrusions 232 on both sides in the width direction, and an upwardly bent protrusion 233 is provided in the middle of the drive pressure plate 230. The reinforcing protrusion of the drive pressure plate 230 includes the aforementioned protrusions 232 and bent protrusions 233.

[0060] Furthermore, a connecting arm 240 is fixedly connected to one side of the clamp 211, and the end of the connecting arm 240 away from the clamp 211 is rotatably connected to the push rod structure 400. Specifically, as shown... Figure 2As shown, by setting a connecting arm 240, the connecting arm 240, the column 120, and the push rod structure 400 form a triangular shape. When the push rod structure 400 extends or retracts, the included angle between the connecting arm 240 and the column 120 in this triangle changes, thereby causing the main beam 110 to rotate relative to the column 120, thus realizing the angle adjustment of the main beam 110.

[0061] It should be noted that, since there are driving parts and driven parts in the photovoltaic power generation system 20, the driven part does not need to be equipped with push rod structure 400. Correspondingly, there is no need to set up connecting support arm 240 at the driven part. Therefore, in some embodiments, the connecting support arm 240 can be configured to be detachably connected to the clamp 211.

[0062] Please refer to the reference. Figures 1-3 In this embodiment, the first rotating connector 210 further includes an arc-shaped component 213, with the clamping component 211 fixedly connected to the arc-shaped component 213, and the arc-shaped component 213 having an arc-shaped flange 214. The second rotating connector 220 includes a mounting plate 221 and a roller structure mounted on the mounting plate 221. The roller structure is fixedly engaged with the arc-shaped flange 214 so that the second rotating connector 220 is rotatably connected to the first rotating connector 210.

[0063] Specifically, the arc-shaped component 213 includes a connecting edge 215 and an arc-shaped flange 214. The connecting edge 21 has an arc-shaped outer contour and an inner contour that matches the shape of the clamp component 211. The connecting edge 21 is fixed to the outer periphery of the clamp component 211, and the outer edge of the connecting edge 21 is arc-shaped. The axis of this arc is the rotation axis of the main beam 110. The arc-shaped flange 214 is disposed on the arc-shaped outer contour of the connecting edge 21 and is perpendicular to the connecting edge 21. The roller structure mounted on the mounting plate 221 includes a first roller 222 and a second roller 223. The first roller 222 and the second roller 223 are staggered vertically, so that the first roller 222 and the second roller 223 are located on the upper and lower sides of the arc-shaped flange 214 and are fixedly engaged with the arc-shaped flange 214, thereby realizing the rotatable connection between the first rotating connector 210 and the second rotating connector 220. In this embodiment, the second rotating connector 220 includes two mounting plates 221 spaced apart, a roller structure is disposed between the two mounting plates 221, and the two ends of the roller structure's rotating shaft are respectively rotatably mounted on the two mounting plates 221.

[0064] Furthermore, the arc-shaped component 213 is provided with multiple first positioning holes 216, and the mounting plate 221 is provided with multiple second positioning holes 224. The adjustable fixed photovoltaic bracket 10 also includes a positioning pin, which is a first positioning pin 250, used to lock and fix the relative rotation of the first rotating connector 210 and the second rotating connector 220 (e.g., Figure 6(As shown). When the locating pin is simultaneously inserted into the first locating hole 216 and the second locating hole 224, it can lock the relative rotation between the first rotating connector 210 and the second rotating connector 220. When it is necessary to adjust the angle of the main beam 110, the locating pin can be pulled out.

[0065] Figure 7 This diagram shows the structure of the bearing arc connector 300 in the adjustable fixed photovoltaic bracket 10 provided in this embodiment. Figure 8 This diagram illustrates the structure of the column 120 in the adjustable fixed photovoltaic support 10 provided in this embodiment. Please refer to the diagram for further details. Figures 1-8 In this embodiment, the adjustable fixed photovoltaic bracket 10 also includes a bearing arc connector 300, the upper end of which is fixedly connected to the bearing arc assembly 200, and the lower end of which is fixedly connected to the column 120.

[0066] Specifically, the lower end of the second rotating connector 220 has a U-shaped connecting structure, which includes oppositely disposed connecting ears 225, and is fixedly connected to the bearing arc connector 300 through the connecting ears 225. The bearing arc connector 300 is a C-shaped part, and the column 120 is also a C-shaped part, such as... Figure 2 As shown, the size of the bearing arc connector 300 is slightly smaller than that of the column 120. After connection, the bearing arc connector 300 is embedded in the column 120.

[0067] Optionally, the bearing arc connector 300 is provided with a third connecting hole 311, and the column 120 is provided with a fourth connecting hole 121. The third connecting hole 311 and / or the fourth connecting hole 121 are distributed in multiple positions along the height direction, so that the height of the bearing arc connector 300 relative to the lower end of the column 120 can be adjusted by adjusting the corresponding position of the third connecting hole 311 and the fourth connecting hole 121.

[0068] Specifically, in this embodiment, there are multiple third connecting holes 311, which are arranged in multiple rows along the height direction. The fourth connecting hole 121 is a gourd-shaped hole formed by multiple interconnected through holes. By aligning the different positions of the third connecting holes 311 and the fourth connecting holes 121 at different heights and locking them with bolts, the bearing arc connector 300 can be connected to the column 120 at different height positions. In this way, the main beam 110 supported can be located at different heights from the ground. Even if the adjustable fixed photovoltaic bracket 10 is installed on undulating slopes, it can adapt to the installation and has strong slope adaptability.

[0069] Figure 9 This diagram shows a schematic of the push rod structure 400 in the adjustable fixed photovoltaic bracket 10 provided in this embodiment. Figure 10A schematic diagram of the push rod base 500 in the adjustable fixed photovoltaic bracket 10 provided in this embodiment is shown. Please refer to the following: Figures 1-10 In this embodiment, the push rod structure 400 includes a rotating rod 411, a fixed rod 412, and a movable rod 413. The fixed rod 412 is mounted on the first column 122, and the movable rod 413 is connected to the main beam 110. The rotating rod 411 is rotatably mounted on the fixed rod 412, and the movable rod 413 is drively connected to the rotating rod 411. The rotating rod 411 is used to drive the movable rod 413 to extend or retract relative to the fixed rod 412 when rotating, thereby pushing the main beam 110 to rotate relative to the column 120. Simultaneously, when the rotating rod 411 is not rotating, the push rod structure 400 supports the main beam 110 at its current angular position.

[0070] Specifically, one end of the movable rod 413 is inserted into the fixed rod 412, and the other end of the movable rod 413 is rotatably connected to the connecting support arm 240. The end of the fixed rod 412 away from the movable rod 413 is rotatably connected to the first column 122. The rotating rod 411 is rotatably mounted on the fixed rod 412, and the rotating rod 411 is driven to the movable rod 413. The rotation of the rotating rod 411 can drive the movable rod 413 to move relative to the fixed rod 412, thereby realizing the telescopic movement of the push rod structure 400. Optionally, the transmission connection between the rotating rod 411 and the movable rod 413 can adopt a gear and rack structure.

[0071] Optionally, the adjustable fixed photovoltaic bracket 10 further includes a push rod base 500, which is fixedly connected to the first column 122. The push rod base 500 has a first mounting portion 511 and a second mounting portion 521 disposed opposite to each other. The lower end of the push rod structure 400 is located between the first mounting portion 511 and the second mounting portion 521, and the push rod structure 400 is rotatably connected to the first mounting portion 511 and the second mounting portion 521.

[0072] Specifically, the push rod base 500 includes a first U-shaped member 510 and a second U-shaped member 520. The two free arms of the first U-shaped member 510 are fixedly connected to both sides of the first column 122, thereby achieving a fixed connection between the push rod base 500 and the first column 122. The two free arms of the second U-shaped member 520 are fixedly connected to the base plate of the first U-shaped member 510, thereby forming a circumferentially closed rectangular space. The base plate of the first U-shaped member 510 forms a first mounting portion 511, and the base plate of the second U-shaped member 520 forms a second mounting portion 521.

[0073] Figure 11 This diagram shows the structure of the support rod 600 in the adjustable fixed photovoltaic bracket 10 provided in this embodiment. Figure 12 A schematic diagram of the second positioning pin 612 in the adjustable fixed photovoltaic bracket 10 provided in this embodiment is shown. Please refer to the attached diagram. Figures 1-12Furthermore, for high-level supports (i.e., the column 120 reaches a certain height), in order to ensure the convenience and stability of the support angle adjustment, support rods 600 can be set at least some of the driven parts. After rotational adjustment, the support rods 600 support the main beam 110 and the column 120. Specifically, the column 120 with the support rods 600 is the second column 123. The structure of the first column 122 is basically the same as that of the second column 123, and the second column 123 also supports the main beam 110 through the bearing arc assembly 200.

[0074] It should be noted that the structure of the driven parts is not limited here, and the driven parts do not necessarily need to be supported by support rods 600. For example, if the height of the column 120 is low, the driven parts may not be equipped with support rods 600. Alternatively, if the column 120 reaches a certain height, support rods 600 may be installed in some driven parts, while other driven parts may not be equipped with support rods 600 (e.g., ...). Figure 1 (As shown).

[0075] The following describes the support structure and operating principle of the bracket with support rod 600: In this embodiment, the adjustable fixed photovoltaic bracket 10 also includes support rod 600 and positioning pin, which is a second positioning pin 612. The upper end of support rod 600 is rotatably connected to the main beam 110, and the lower end of support rod 600 is slidably connected to the second column 123 to adapt to supporting the main beam 110 at different angles. The second positioning pin 612 is used to cooperate with support rod 600 and the second column 123 to lock the relative movement of support rod 600 and the second column 123. When the second positioning pin 612 locks the sliding of support rod 600 relative to the second column 123, the rotation of support rod 600 relative to the main beam 110 is locked, and at this time, support rod 600 can effectively support the main beam 110.

[0076] Specifically, the support rod 600 is a long rod-shaped component with multiple insertion holes 611 along its length. The upper end of the support rod 600 along its length is rotatably connected to the connecting arm 240 at the driven part. A mounting part 124 is installed on the second column 123. The mounting part 124 has a through hole. When the second positioning pin 612 passes through the through hole and is inserted into one of the insertion holes 611 on the support rod 600, the relative sliding between the support rod 600 and the second column 123 is locked. At this time, the support rod 600, the second column, and the connecting arm 240 form a stable triangular support structure, providing support for the main beam 110 and also locking the main beam 110 from rotating relative to the column 120.

[0077] It should be noted that, since the first positioning pin 250 provided at the bearing arc assembly 200 in this embodiment also plays the role of locking the main beam 110 relative to the column 120, the positions of the multiple insertion holes 611 on the support rod 600 can be matched with the positions of the first positioning hole 216 and the second positioning hole 224 on the bearing arc assembly 200.

[0078] The adjustable fixed photovoltaic bracket 10 and photovoltaic power generation system 20 provided in the embodiments of this utility model, when it is necessary to adjust the angle of the photovoltaic module 23 to track the solar tilt angle, firstly, it is necessary to ensure that the rotation of the first rotating connector 210 and the second rotating connector 220 is in the unlocked state, that is, the first positioning pin 250 and the second positioning pin 612 are not in the locked state; then, rotate the rotating rod 411, so that the movable rod 413 moves relative to the fixed rod 412, the push rod structure 400 extends and retracts, thereby driving the clamp 211 and the main beam 110 which is circumferentially fixed to the clamp 211 to rotate relative to the column 120. At the same time, the torsional force can be transmitted to other driven parts through the main beam 110, so that a single person can realize the angle adjustment work of the entire row. After rotating to the desired angle, the operator stops rotating the rotating rod 411. At this point, the push rod structure 400 provides strong diagonal support to the main beam 110, ensuring the stability of the bracket. Furthermore, the first positioning pin 250 engages with the first positioning hole 216 and the second positioning hole 224 to lock relative rotational movement. The second positioning pin 612 engages with the insertion hole 611 and the through hole on the mounting piece 124, allowing the support rod 600 to provide support force. Moreover, this structure is simple, employs a modular design, and the structures of the driving and driven parts are basically the same. Only the push rod structure 400 needs to be added to the driving part, making manufacturing and installation convenient and cost-effective.

[0079] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
