Description

Technical Field

[0001] This utility model relates to the field of photovoltaic construction technology, specifically to a flexible photovoltaic module with adjustable angle for easy installation. Background Technology

[0002] In the renovation project of abandoned tea gardens on slopes in the northeastern part of the Sichuan Basin and surrounding hilly areas, a "tea-solar complementary" model is being explored to improve the economic benefits of the land. These tea gardens are mostly located on shady or semi-shady slopes with an angle of 25°–40°. Deploying photovoltaic panels on such plots can not only generate electricity and increase income, but also create a suitable light environment for tea trees (such as the Sichuan tea variety) that prefer diffused light through the shading rate of the photovoltaic panels. Due to the large variations in slope aspect and gradient in these tea garden plots, the photovoltaic panels must be easy to install and adaptable to different slope terrains. Given the seasonal variation in solar altitude angle in the Sichuan Basin (nearly 80° in summer and only about 30° in winter), the tilt angle of the photovoltaic panels must be adjustable to avoid a sudden drop in power generation or excessive sunlight exposure for the tea trees. Furthermore, due to the high humidity and foggy environment of these tea gardens, the tilt angle adjustment scheme for the photovoltaic panels should be simple, practical, and easy to adjust. Utility Model Content

[0003] The purpose of this utility model is to provide a flexible photovoltaic module with adjustable angle that is easy to install. It has a simple structure, low cost, is suitable for installation in different slope terrain environments and is easy to install. It also has the function of adjusting the tilt angle of the photovoltaic panel.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An adjustable-angle, easy-to-install flexible photovoltaic module includes a flexible photovoltaic mechanism and two photovoltaic supports. The flexible photovoltaic mechanism includes two parallel load-bearing cables and several photovoltaic panels arranged in a linear array. Both ends of each photovoltaic panel are fixedly connected to the two load-bearing cables. The two photovoltaic supports are symmetrically arranged, and both ends of each load-bearing cable are connected to the two photovoltaic supports. Each photovoltaic support includes side columns, crossbeams, through-bolts, and diagonal bracing mechanisms.

[0006] The bottom end of the side column is provided with a foundation flange. The top of the side column has a first through hole and a second through hole machined radially downwards. A through-groove is formed in the middle of the crossbeam from top to bottom, the length of which is greater than the radial dimension of the side column. A through hole is formed in the middle of the crossbeam longitudinally. The ends of the two load-bearing cables are fixedly connected to both ends of the crossbeam. The side column passes through the through-groove, and the through-bolt passes through the first through hole and the through hole.

[0007] The diagonal bracing mechanism includes a strut, a pin, a positioning plate, a mounting screw, and a clamp. The positioning plate is fixed to the underside of the crossbeam. Several limiting holes are machined on the positioning plate in a straight line array. A through mounting hole is opened on the clamp in the radial direction. The clamp is sleeved on the side column. The mounting screw passes through the mounting hole and the second through hole. One end of the strut is rotatably sleeved on a connecting bolt of the clamp. The other end of the strut is rotatably connected to any of the limiting holes through a pin.

[0008] Furthermore, the photovoltaic support also includes a stay cable and a turnbuckle. The end of the threaded rod is machined with a radial cable hole. One end of the stay cable passes through the radial cable hole and is fixedly connected to the cable body of the stay cable by a rope clamp. Both ends of the turnbuckle are threaded with a stay ring. The other end of the stay cable passes through one of the stay rings and is fixedly connected to the cable body of the stay cable by a rope clamp.

[0009] Specifically, the photovoltaic support also includes an external anchoring bolt, an internal anchoring bolt, and an anchoring nut. A through longitudinal hole is provided at the end of the crossbeam. One end of the external anchoring bolt passes through the longitudinal hole and is threadedly connected to the anchoring nut. The anchoring nut is used to fix the external anchoring bolt to the crossbeam. One end of the internal anchoring bolt passes through the external anchoring bolt and is threadedly connected to the external anchoring bolt. A load-bearing pull ring is fixedly provided at the other end of the internal anchoring bolt. One end of the load-bearing cable passes through the load-bearing pull ring and is fixedly connected to the cable body of the load-bearing cable through a rope clamp.

[0010] Furthermore, photovoltaic clamps are provided near the four corners of the photovoltaic panel. Each photovoltaic clamp includes an upper clamping plate, a lower clamping plate, and U-bolts. The upper clamping plate and the lower clamping plate are arranged parallel to each other. A guide is connected to one side of the upper clamping plate, and the guide is slidably adapted to the lower clamping plate. Two through holes are provided on both the upper and lower clamping plates. The two ends of the U-bolt pass through the two through holes of the lower clamping plate and then through the two through holes of the upper clamping plate. Locking caps are threaded to both ends of the U-bolt. Tightening the locking caps can clamp the load-bearing cable between the middle of the U-bolt and the lower clamping plate, and clamp the photovoltaic panel between the upper and lower clamping plates.

[0011] The beneficial effects of this utility model are:

[0012] In this utility model, a flexible photovoltaic module with adjustable angle for easy installation includes a photovoltaic support structure comprising a side column, a crossbeam, a through-bolt, and a diagonal bracing mechanism. The top of the side column has a first through hole and a second through hole machined radially downwards. A through-slot is formed in the middle of the crossbeam from top to bottom, and a through hole is formed longitudinally in the middle of the crossbeam. The side column passes through the through-slot, and the through-bolt passes through the first through hole and the through hole. The diagonal bracing mechanism includes a support rod, a pin, a positioning plate, a mounting screw, and a clamp. The positioning plate is fixed to the lower side of the crossbeam and has several limiting holes machined in a linear array. The clamp has a through-mounting hole in the radial direction and is fitted onto the side column. The mounting screw passes through the mounting hole and the second through hole. One end of the support rod is rotatably fitted onto a connecting bolt of the clamp, and the other end of the support rod is rotatably connected to any of the limiting holes via a pin. The side columns, crossbeams, and diagonal bracing mechanisms are all manufactured independently and can be easily and quickly assembled on-site, making transportation and assembly extremely convenient when used in sloping environments. Simultaneously, the entire structure is extremely simplified, containing no electric components or transmission mechanisms, eliminating potential corrosion and malfunctions caused by high humidity in shady slope environments. Because the crossbeam tilts at different angles when the support rods connect to different limit holes, this flexible photovoltaic module also features photovoltaic panel tilt adjustment. In hot, sunny summer weather, the adjustable angle creates significant shading, reducing surface temperature in the tea garden, decreasing tea tree transpiration, and improving tea quality. In cold, low-light winter weather, the adjustable angle increases light transmission, raises ground temperature, and prevents frost damage to tea trees. For the connection between the photovoltaic panels and the load-bearing cables, a photovoltaic clamp is designed. The special shape of the U-bolt allows for simultaneous fixed connection between the photovoltaic clamp, the load-bearing cables, and the photovoltaic panels, making the installation of the photovoltaic panels extremely convenient.

Detailed Implementation

[0019] The technical solution of this utility model is described in further detail below with reference to the accompanying drawings, but the scope of protection of this utility model is not limited to the following description.

[0020] like Figure 1 As shown, a flexible photovoltaic module with adjustable angle for easy installation includes a flexible photovoltaic mechanism and two photovoltaic supports. The flexible photovoltaic mechanism includes two parallel load-bearing cables 1 and several photovoltaic panels 2 arranged in a linear array. The two ends of the photovoltaic panels 2 are fixedly connected to the two load-bearing cables 1 respectively. The two photovoltaic supports are symmetrically arranged, and the two ends of the load-bearing cables 1 are connected to the two photovoltaic supports respectively.

[0021] The structure of the photovoltaic support is as follows Figures 2 to 4 As shown, the structure includes separately processed or manufactured side columns 3, crossbeams 4, through-bolts 12, and diagonal bracing mechanisms. The side column 3 is a straight column structure with a foundation flange 5 at its bottom. The top of the side column 3 has a first through hole and a second through hole processed sequentially from top to bottom, both penetrating radially through the side column 3. The crossbeam 4 is a straight beam structure with a through-groove 6 formed in its middle section from top to bottom. The length of the through-groove 6 is greater than the radial dimension of the side column 3. A through hole is formed in the middle of the crossbeam 4 along its longitudinal direction (perpendicular to the extension direction of the crossbeam 4). The diagonal bracing mechanism includes a strut 7, a pin, a positioning plate 8, a mounting screw 9, and a clamp 10. The positioning plate 8 has several limiting holes 11 machined along a straight line array. The positioning plate 8 is fixed to the lower side of the crossbeam 4 by welding or other means. The clamp 10 is machined from commercially available double-bolt clamp parts. It includes two semi-circular bands. The two bands are connected into a ring shape by two connecting bolts. After being assembled into the clamp 10 during processing, mounting holes are machined through the clamp 10 in the radial direction.

[0022] During assembly: the bottom end of the side column 3 is connected to the foundation foundation with anchor bolts through the foundation flange 5, the top end of the side column 3 is inserted into the limiting groove 6 of the crossbeam 4, the through pin 12 is inserted into the first through hole of the side column 3 and the through hole of the crossbeam 4 and the nut is tightened at the end of the through pin 12 to fix it. The through pin 12 enables the side column 3 and the crossbeam 4 to be rotatably connected, and at the same time the limiting groove 6 limits the swing angle between the side column 3 and the crossbeam 4 to a certain range. The clamp 10 is fitted onto the side column 3 by installing clamps on both sides of the side column 3. The mounting screw 9 passes through the mounting hole on the clamp 10 and the second through hole of the side column 3, and is fixed by tightening the nut at the end of the mounting screw 9. When assembling the clamp 10, one end of the support rod 7 is directly and rotatably fitted onto a connecting bolt of the clamp 10, and the other end of the support rod 7 is rotatably connected to a suitable limiting hole 11 through a pin (or bolt in practice) according to the required tilt angle of the photovoltaic panel.

[0023] As can be seen from the above, this adjustable-angle flexible photovoltaic module has a simple overall structure and low cost. The side columns 3, crossbeams 4, and diagonal bracing mechanisms are all manufactured independently and can be easily assembled on-site. The transportation and assembly process is extremely convenient when used in sloping environments. At the same time, the entire structure is extremely simplified, containing no electric components or transmission mechanisms, eliminating the possibility of equipment corrosion and malfunctions caused by high humidity in shady slope environments. Because the crossbeam 4 tilts at different angles when the support rod 7 connects to different limiting holes 11, this flexible photovoltaic module also has a photovoltaic panel tilt angle adjustment function. In the high temperatures and strong sunlight of summer, the adjustable angle can create greater shading, reducing the surface temperature of the tea garden, reducing tea tree transpiration, and improving tea quality. In the low temperatures and weak sunlight of winter, the adjustable angle can increase light transmission, raise the ground temperature, and prevent frost damage to the tea trees.

[0024] Furthermore, such as Figure 2 As shown, the photovoltaic support also includes a stay cable 21 and a turnbuckle 13. A radial cable hole is machined at the end of the threaded rod 12. One end of the stay cable 21 passes through this radial cable hole and is fixedly connected to the cable body of the stay cable 21 via a rope clamp. Diagonal rings are threaded to both ends of the turnbuckle 13. The other end of the stay cable 21 passes through one of the diagonal rings and is fixedly connected to the cable body of the stay cable 21 via a rope clamp. The other diagonal ring and the foundation ring are connected by a cable. The stay cable 21 provides the preload of the photovoltaic support. The radial cable hole at the end of the threaded rod 12 makes installation of the end of the stay cable 21 away from the foundation ring extremely convenient, while also allowing the tension of the stay cable 21 to act directly on the threaded rod 12, and further directly on the middle of the crossbeam 4 and the side columns 3. The turnbuckle 13 has opposite threads at both ends. After the photovoltaic support is installed on the working foundation, the preload of the cable 21 can be directly adjusted by rotating the turnbuckle 13. The process of adjusting the preload is also very convenient.

[0025] Specifically, such as Figure 3 , Figure 4 As shown, the photovoltaic support also includes an external anchoring screw 14, an internal anchoring screw 15, and an anchoring nut. Both ends of the crossbeam 4 are provided with through longitudinal holes. One end of the external anchoring screw 14 passes through the longitudinal hole and is threadedly connected to the anchoring nut. Tightening the anchoring nut can fix the external anchoring screw 14 to the crossbeam 4. One end of the internal anchoring screw 15 passes through the external anchoring screw 14 and is threadedly connected to the external anchoring screw 14. The other end of the internal anchoring screw 15 is fixedly provided with a load-bearing pull ring 16. One end of the load-bearing cable 1 passes through the load-bearing pull ring 16 and is fixedly connected to the cable body of the load-bearing cable 1 through a rope clamp. This achieves a fixed connection between the load-bearing cable 1 and the crossbeam 4. The preload of the load-bearing cable 1 can be adjusted by rotating the internal anchoring screw 15.

[0026] Furthermore, photovoltaic clamps are installed near the four corners of the photovoltaic panel 2, such as... Figure 5 As shown, the photovoltaic clamp includes an upper clamping plate 17, a lower clamping plate 18, and U-bolts 19. The upper clamping plate 17 and the lower clamping plate 18 are arranged parallel to each other. A guide member 20 is connected to one side of the upper clamping plate 17. The guide member 20 is slidably adapted to the lower clamping plate 18 (in implementation, the guide member 20 is a sliding column, and a sliding hole is machined on the lower clamping plate 18, in which the guide member 20 is slidably disposed). Both the upper clamping plate 17 and the lower clamping plate 18 have two through holes. The two ends of the U-bolt 19 first pass through the lower clamping plate 18 respectively. The two through holes of the U-bolt 19 are then passed through the two through holes of the upper clamping plate 17. Locking caps are then threaded onto both ends of the U-bolt 19. When the locking caps are tightened, the load-bearing cable 1 is clamped between the middle of the U-bolt 19 and the lower clamping plate 18, and the photovoltaic panel 2 is clamped between the upper clamping plate 17 and the lower clamping plate 18. Thus, the special shape of the U-bolt 19 is used to simultaneously achieve the fixed connection between the photovoltaic clamp and the load-bearing cable 1 and the photovoltaic panel 2, and the installation process of the photovoltaic panel is also extremely convenient.
