Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic installation equipment, and particularly to a flexible photovoltaic support for large-slope mountains with stable structure. Background Art

[0002] As an innovative photovoltaic installation solution, flexible photovoltaic supports have been widely used in the construction of photovoltaic power stations in recent years. This support system uses flexible connection materials, such as steel wires, etc. Through flexible layout and structural design, it can adapt to various complex terrains, reduce installation costs, and improve the efficiency of solar energy collection. Especially in some areas with rough terrain and limited soil bearing capacity, flexible supports have become the preferred solution for the construction of photovoltaic power stations by virtue of their unique advantages. It can not only effectively support photovoltaic panels, but also automatically adjust the angle of photovoltaic panels according to the change of light angle, so as to maximize the utilization of solar energy resources.

[0003] When existing flexible supports are applied to large-slope mountains, their stability and safety face severe challenges. Especially in areas with strong wind pressure, due to the special terrain of the mountains, the action of wind load will be more complex and changeable. And in order to increase the efficiency of solar energy collection, photovoltaic panels are usually arranged obliquely. Traditional flexible supports often lack a response mechanism for high-wind-pressure environments, resulting in the fact that under strong wind action, photovoltaic panels are easily damaged, and the support structure may also deform or collapse due to being unable to withstand the huge wind pressure. In addition, the height difference of the terrain of large-slope mountains also brings great inconvenience to the installation and maintenance of flexible supports. Summary of the Invention

Flow guide plates are arranged on the inner wall of the second collar. The inner cavities of the first collar and the third collar are communicated with each other through the flow guide plates. Hydraulic oil is arranged in the inner cavities of the first collar and the third collar. Embedding blocks are arranged on the inner wall of the third collar.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, when there is a large wind pressure at the installation position of the photovoltaic panel, the rotating shaft disengages from the lock of the locking mechanism and rotates under the action of the wind force. The photovoltaic panel is driven to rotate by the rotating shaft, so that the angle of the photovoltaic panel is automatically adjusted to the minimum windward surface. After the photovoltaic panel is adjusted to the optimal windward angle, the force received is reduced, and then the photovoltaic panel is locked by the locking mechanism, significantly improving the stability of the flexible support. 2. In the present invention, aiming at the problem that the support is prone to deformation in a high-wind pressure environment, a support cable is added to the support in the present invention. When the wind load increases, that is, when the locking mechanism stops locking the rotating shaft, the support cable is tightened to increase its tension, and then the stability of the support column is increased. When the wind load decreases, the tension of the support cable is reduced to avoid wear caused by excessive tension. 3. In the present invention, in an environment where there is an obvious height difference between high and low ground on a large slope mountain, by providing a stabilizing sleeve, it is convenient to add an elevation adjuster to the support column to increase the overall height of the support column, solving the installation problem caused by the height difference of the terrain. At the same time, the stabilizing sleeve further tightens the connection of the support under the action of wind pressure, ensuring the overall stability of the support system.

Detailed implementation manners

[0016] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0017] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0018] Please refer to Figures 1-8 , the present invention provides a technical solution: A flexible photovoltaic bracket for large-slope mountainous areas with stable structure, comprising Support pillars 1, the number of support pillars 1 is at least two and they are evenly installed on the ground. An installation seat 4 is arranged at the top of the support pillar 1. Two load-bearing ropes 41 are arranged inside the installation seat 4. A photovoltaic panel 3 is installed at the top of the load-bearing rope 41. The support pillar 1 is composed of a lower base pillar 11 and an upper base pillar 12. A fixed hoop 15 is further arranged on the outer side of the upper base pillar 12. A lifting frame 13 is arranged at the connection end of the lower base pillar 11 and the upper base pillar 12. A stabilizing sleeve 14 is arranged at the top of the inner cavity of the lower base pillar 11, and the lifting frame 13 is fixed through the stabilizing sleeve 14; A rotating shaft 42 is arranged between the two load-bearing ropes 41 and is fixedly connected to the two load-bearing ropes 41 respectively. A locking pin 43 is arranged at one end of the rotating shaft 42, and the inclination angle of the photovoltaic panel 3 is adjusted by rotating the rotating shaft 42; The locking mechanism 44 is arranged at one end of the locking pin 43. The rotating shaft 42 is locked by the locking mechanism 44 to prevent its rotation. The locking mechanism 44 includes an upper tightening ring 441 and a lower tightening ring 442. Positioning holes 443 are formed in the inner sides of the upper tightening ring 441 and the lower tightening ring 442. A plurality of mounting holes 431 are formed in the contact end of the locking pin 43 with the locking mechanism 44. A locking ball 433 is arranged in the inner cavity of the mounting hole 431, and the locking ball 433 is adapted to the positioning hole 443.

[0019] In this embodiment, please refer to Figure 3 , Figure 4 , Figure 8 , a ground pile 2 is arranged on one side of the support column 1. A support cable 5 is arranged at the top of the ground pile 2. The support cable 5 is fixedly connected to one side of the support column 1. A winding roller 151 is arranged inside the fixing hoop 15. A gear 152 is arranged on one side of the winding roller 151. One end of the support cable 5 is wound on the outer side of the winding roller 151. A rack 445 is arranged on one side of the upper tightening ring 441. One side of the rack 445 meshes with the outer edge of the gear 152. In this embodiment, by connecting a support cable 5 on one side of the support column 1, an additional fixing point is provided for the support column 1, which can effectively resist the overturning moment of the flexible support under the action of wind load or other external forces and form a triangular stable structure, thereby enhancing the anti-overturning ability of the support. At the same time, since the upper tightening ring 441 will move upward under the action of strong wind pressure, the rack 445 will be driven to move upward, thereby driving the winding roller 151 to rotate, so that one end of the support cable 5 is wound, the support cable 5 is tensioned and the tension is increased. When the flexible support is subjected to strong wind, the tension of the support cable 5 is increased to make it taut, resisting the wind load, reducing the relaxation and vibration caused by wind vibration, and improving the stability of the overall structure.

[0020] In this embodiment, please refer to Figure 3 , second torsion springs 444 are arranged at the contact positions of both ends of the lower tightening ring 442 with the upper tightening ring 441. A spring 432 is further arranged in the inner cavity of the mounting hole 431. One end of the spring 432 is in contact with the locking ball 433. In this embodiment, as the wind pressure received by the photovoltaic panel 3 decreases, that is, when the acting force of the wind pressure is less than the elastic forces of the second torsion spring 444 and the spring 432, the second torsion spring 444 and the spring 432 return to their original states, driving the upper tightening ring 441 and the lower tightening ring 442 back to their original positions. Along with the rotation of the locking pin 43, the locking ball 433 is re-embedded into the inner cavity of the positioning hole 443, locking the angle of the photovoltaic panel 3 at the minimum wind receiving surface.

[0021] In this embodiment, please refer to Figures 5-6, the stabilizing sleeve 14 includes a first sleeve ring 141, a second sleeve ring 142, and a third sleeve ring 144. A pressure block 1411 is provided on the inner wall of the first sleeve ring 141, and a flow guide plate 143 is provided on the inner wall of the second sleeve ring 142. The inner cavities of the first sleeve ring 141 and the third sleeve ring 144 are interconnected through the flow guide plate 143. Hydraulic oil is provided in the inner cavities of both the first sleeve ring 141 and the third sleeve ring 144. An embedding block 1442 is provided on the inner wall of the third sleeve ring 144, and an installation groove 131 adapted to the embedding block 1442 is formed on the outer side of the bottom end of the height-adjusting frame 13. In this embodiment, when the height-adjusting frame 13 is inserted into the inner cavity of the lower base column 11, the outer side of the height-adjusting frame 13 presses the pressure block 1411 to increase the pressure in the inner cavity of the first sleeve ring 141. By adjusting the position of the height-adjusting frame 13, after the installation groove 131 corresponds to the embedding block 1442, under the action of the pressure, the embedding block 1442 is pushed to enter the inner cavity of the installation groove 131, thereby fixing the height-adjusting frame 13 on the top of the lower base column 11. At the same time, when the upper base column 12 shakes under the action of wind pressure, the pressure block 1411 will be continuously pressed, causing sufficient pressure to be generated in the inner cavities of the first sleeve ring 141 and the third sleeve ring 144. Under the action of the pressure, the contact between the embedding block 1442 and the inner cavity of the installation groove 131 becomes closer, thereby making the connection of the support column 1 more stable and further enhancing the wind resistance of the flexible support.

[0022] In this embodiment, please refer to Figure 7 , a threaded hole 1423 is formed on the outer side of the second sleeve ring 142. A bolt 1421 is provided on the inner wall of the threaded hole 1423. One end of the bolt 1421 is fixedly connected with a sealing seat 1422. An overflow groove 1431 is formed on one side of the flow guide plate 143. In this embodiment, by rotating the bolt 1421 to move it along the threaded hole 1423 and driving the sealing seat 1422 to move, when the sealing seat 1422 moves, a gap appears between it and the overflow groove 1431. Thus, the hydraulic oil in the inner cavities of the first sleeve ring 141 and the third sleeve ring 144 flows out through the gap under the action of the pressure, reducing the pressure in the inner cavities of the first sleeve ring 141 and the third sleeve ring 144. Thereby, the embedding block 1442 can be taken out from the inner cavity of the installation groove 131, and the height-adjusting frame 13 can be disassembled from the lower base column 11. This setting can make the installation and removal of the flexible support more convenient, and the installation and removal processes are fast and convenient.

[0023] In this embodiment, please refer to Figure 6, on one side of the embedding block 1442, a first torsion spring 1441 is arranged, and the first torsion spring 1441 is connected to the inner cavity of the third collar 144. In this embodiment, when the embedding block 1442 is pushed into the inner cavity of the installation groove 131 under the action of pressure, the first torsion spring 1441 is stretched and deformed. When the pressure in the inner cavity of the third collar 144 is less than the pulling force of the first torsion spring 1441, the first torsion spring 1441 rebounds and drives the embedding block 1442 to move backward, so that it disengages from the inner cavity of the installation groove 131, thus facilitating the disassembly of the lower base column 11 and the upper base column 12.

[0024] In this embodiment, please refer to Figure 1 , a wind-resistant cable 6 is connected between two adjacent struts 1. The struts 1 are supported by the support cable 5 and the wind-resistant cable 6. In this embodiment, the wind-resistant cables 6 connected between adjacent brackets form an additional connection structure, which can transfer and disperse loads between the struts 1, making the force of the entire bracket system more uniform. Under the action of wind load or other external forces, the wind-resistant cables 6 between adjacent struts 1 can jointly resist deformation, thereby enhancing the overall stability of the entire flexible bracket.

[0025] In this embodiment, please refer to Figure 2 , an activity groove 45 is opened inside the mounting seat 4. One end of the load-bearing rope 41 is arranged in the inner cavity of the activity groove 45, and rubber pads are arranged at both ends of the inner cavity of the activity groove 45. In this embodiment, by providing the activity groove 45, when the rotating shaft 42 rotates, the load-bearing rope 41 moves in the inner cavity of the activity groove 45, so that a height difference is formed between the two load-bearing ropes 41, thereby adjusting the angle of the photovoltaic panel 3. At the same time, by providing rubber pads, when the photovoltaic panel 3 rotates under the action of wind pressure, a buffer is provided to improve the stability of the load-bearing rope 41.

[0026] In this embodiment, please refer to Figures 1-2 , a light intensity sensor is arranged on the top of the mounting seat 4, and a servo motor is arranged at one end of the rotating shaft 42 away from the locking pin 43. The rotating shaft 42 can be driven to rotate by the servo motor. In this embodiment, when the wind pressure is lower than the bearing range of the flexible bracket, the irradiation angle of sunlight is detected by the light intensity sensor, and the rotating shaft 42 is controlled to rotate by the servo motor. When the rotating force exceeds the elastic forces of the spring 432 and the second torsion spring 444, the rotating shaft 42 and the locking pin 43 rotate, changing the orientation of the photovoltaic panel 3, so as to adjust the orientation of the photovoltaic panel 3 according to the direction of light and increase the light energy collection efficiency of the photovoltaic panel 3.

[0027] The working principle of the present invention: Step 1: When strong winds occur in the area where the photovoltaic panels are installed, due to their large surface area and for the sake of light energy collection efficiency, the photovoltaic panels 3 are usually arranged in an inclined manner. Therefore, the photovoltaic panels 3 are subjected to a relatively large wind pressure. When the photovoltaic panels 3 are subjected to wind pressure, since they are installed on the load-bearing ropes 41, a pressure is generated on the load-bearing ropes 41, and the pressure is transmitted to the rotating shaft 42 through the load-bearing ropes 41. Since the locking ball 433 is stuck in the inner cavity of the positioning hole 443, the locking pin 43 is locked and cannot rotate, so that the rotating shaft 42 cannot rotate. When the pressure generated by the wind pressure on the photovoltaic panels 3 is too large, the locking ball 433 squeezes the spring 432 to cause it to deform, and pushes the upper tightening ring 441 and the lower tightening ring 442 to increase the distance between them, so that the locking ball 433 disengages from the inner cavity of the positioning hole 443, so that the locking pin 43 can rotate normally. After the locking pin 43 can rotate normally, the rotating shaft 42 can rotate normally. At this time, under the action of the wind pressure, the locking pin 43 rotates, and the two rotating shafts 42 move in the inner cavity of the movable groove 45 respectively, so that the inclination angle of the photovoltaic panels 3 is changed. When the inclination angle of the photovoltaic panels 3 is changed, the wind pressure on the surface of the photovoltaic panels 3 changes accordingly. And because a plurality of positioning holes 443 are provided in the inner cavity of the upper tightening ring 441, when the wind pressure received by the photovoltaic panels 3 is reduced to less than the elastic forces of the second torsion spring 444 and the spring 432, the second torsion spring 444 and the spring 432 return to their original states, causing the locking ball 433, the upper tightening ring 441, and the lower tightening ring 442 to return to their original positions. Along with the rotation of the locking pin 43, the locking ball 433 re-enters the inner cavity of the positioning hole 443, locking the locking pin 43 again, and keeping the inclination angle of the photovoltaic panels 3 at the minimum wind-receiving angle until the wind direction changes and the photovoltaic panels 3 are automatically adjusted again, so that the photovoltaic panels 3 can rotate the inclination angle and the orientation to the state with the minimum wind pressure according to the magnitude and direction of the wind pressure, thus avoiding damage to the photovoltaic panels and excessive pressure on the support; Step 2: By arranging support cables 5 on both sides of the support column 1 and connecting the support cables 5 to ground piles 2 which are fixed to the foundation, the stability of the flexible support of the support column 1 is further increased. At the same time, as the wind pressure on the photovoltaic panel 3 changes, that is, when the wind pressure is large, the distance between the upper tightening ring 441 and the lower tightening ring 442 becomes larger, and the upper tightening ring 441 will move upward. The upward movement of the upper tightening ring 441 drives the rack 445 to move upward. Since one side of the rack 445 meshes with the outer edge of the gear 152, when the rack 445 moves upward, it drives the gear 152 to rotate. The rotation of the gear 152 drives the winding roller 151 to rotate. Since the winding roller 151 is used for winding the support cable 5, when the rack 445 drives the winding roller 151 to rotate, the support cable 5 is wound to the outside of the winding roller 151, so that the overall length of the support cable 5 becomes shorter, making the support cable 5 taut and increasing its tension. Since a larger wind load will generate a greater lateral force on the support column 1 and the support cable 5, the support cable 5 may become slack. At this time, increasing the tension of the support cable 5 makes it taut to resist the wind load, increasing the wind resistance of the flexible support. At the same time, when the wind load becomes smaller, the upper tightening ring 441 and the lower tightening ring 442 return to their original positions under the elastic force of the second torsion spring 444, so that the upper tightening ring 441 moves downward. The downward movement of the upper tightening ring 441 causes the winding roller 151 to reverse, which can reduce the tension of the support cable 5 and avoid excessive tension of the support cable 5 resulting in wear; Step 3: By arranging a stabilizing sleeve 14 at the connection between the lower base column 11 and the height-adjusting frame 13, when the support column 1 is installed on a large slope mountain, due to the different terrain height differences, in order to keep the height of the top of the support column 1 consistent, by replacing the height-adjusting frame 13 with the corresponding length. After the height-adjusting frame 13 is inserted into the inner cavity of the lower base column 11, the outside of the height-adjusting frame 13 presses the pressure block 1411 in the inner wall of the first collar 141, increasing the pressure of the hydraulic oil in the stabilizing sleeve 14. Under the pressure of the hydraulic oil, the embedding block 1442 moves forward. By moving the height-adjusting frame 13 to adjust the position of the installation groove 131 so that it corresponds to the embedding block 1442, under the pressure of the hydraulic oil, the embedding block 1442 enters the inner cavity of the installation groove 131, and then the height-adjusting frame 13 can be completed for installation. And when the flexible support encounters strong wind, the wind pressure generates pressure on the support column 1, causing the upper base column 12 to shake. When the upper base column 12 shakes, it will continuously push the pressure block 1411 to move backward, further increasing the pressure generated by the hydraulic oil in the inner cavity of the first collar 141, so that the connection between the embedding block 1442 and the installation groove 131 is more stable, avoiding loosening at the connection of the support column 1 under the action of the wind pressure, enhancing the wind resistance of the support column 1 and increasing the stability of the flexible support.
