Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic installation equipment, and particularly to a stepped photovoltaic bracket applicable to large-slope mountains. Background Art

[0002] With the increasing global demand for renewable energy, photovoltaic power generation, as a clean and renewable energy form, has been increasingly widely used. In complex terrains such as mountains, the design and installation of photovoltaic brackets face many challenges. Especially in large-slope mountains, where the terrain undulates greatly and the height difference is significant, traditional photovoltaic brackets are difficult to adapt to. Most existing photovoltaic brackets are designed as flat or fixed-inclination types, which are difficult to be flexibly adjusted according to the actual terrain of the mountains, resulting in low installation efficiency of photovoltaic panels and difficulty in maximizing the utilization of sunlight resources. In response to the special needs of mountain photovoltaic power generation, the first-generation flexible brackets have emerged on the market. Such brackets use flexible materials such as steel wires to achieve large-span and high-clearance support, effectively solving the limitations of traditional brackets in complex terrains.

[0003] In the field of photovoltaics, especially in the environment of large-slope mountains, due to the complex mountain terrain and significant height difference, traditional flexible photovoltaic bracket designs often require customized brackets of different lengths to adapt to terrain changes during installation. This not only increases the material cost and manufacturing complexity but also prolongs the installation period. In addition, even if the installation of photovoltaic panels is achieved through brackets of different lengths, it is often difficult to ensure that all photovoltaic panels can receive sunlight at the optimal angle, thus affecting the power generation efficiency.

[0017] 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 scope of protection of this application.

[0018] 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.

[0019] Please refer to Figures 1-8 , the present invention provides a technical solution: A stepped photovoltaic bracket applicable to large-slope mountains includes a photovoltaic panel 1 and fixed piles 2. The number of fixed piles 2 is several and they are evenly fixed on the ground. The fixed piles 2 are used to install and fix the photovoltaic panel 1. An installation frame 3 is arranged between every two vertically arranged fixed piles 2, and one side of the photovoltaic panel 1 is connected to the installation frame 3. Every two horizontally arranged fixed piles 2 are connected by a steel wire rope 4; The fixed pile 2 includes a lower foundation pile 21. A movable column 22 is arranged in the inner cavity of the lower foundation pile 21. An upper foundation pile 23 is arranged at the top of the movable column 22. A top cover 24 is arranged at the top of the upper foundation pile 23. A base 25 is arranged at the bottom of the lower foundation pile 21. The base 25 includes a servo motor 251 and a telescopic rod 252. By driving the telescopic rod 252 to rotate through the servo motor 251, the height of the fixed pile 2 can be adjusted. The base 25 is used to drive the movable column 22 to move upward to adjust the overall height of the fixed pile 2. Positioning mechanisms 26 are respectively arranged on both sides of the movable column 22 in the inner cavity of the lower foundation pile 21; The mounting bracket 3 includes clamping plates 31. A number of connecting members 33 are arranged in the inner cavity of the clamping plates 31. A connecting plate 11 is arranged on one side of the photovoltaic panel 1 connected to the mounting bracket 3. A number of connecting holes 111 are formed in the top of the connecting plate 11. The photovoltaic panel 1 is fixed to one side of the mounting bracket 3 through the connecting members 33 and the connecting holes 111.

[0020] In this embodiment, please refer to Figures 2-4 , the telescopic rod 252 is arranged at the output end of the servo motor 251. A threaded shaft 253 is arranged at the top end of the telescopic rod 252. A threaded groove 211 adapted to the outer side of the threaded shaft 253 is formed in the inner cavity of the lower foundation pile 21. The top end of the threaded shaft 253 is in contact with the bottom of the movable column 22. A light intensity sensor for detecting the sunlight irradiation direction is arranged on the surface of the mounting bracket 3. In this embodiment, the sunlight irradiation direction is detected by the light intensity sensor. Since the sunlight irradiation angle changes gradually during a day, if the orientation of the photovoltaic panel 1 is always fixed, a large amount of solar energy will be wasted. According to the sunlight orientation, the controller starts the servo motor 251, drives the threaded shaft 253 to rotate through the servo motor 251, rotates the threaded shaft 253 in the inner cavity of the threaded groove 211, makes the threaded shaft 253 move upward, and jacks up the movable column 22, so that the height of the movable column 22 increases, and thus the overall height of the fixed pile 2 becomes higher, so that the inclination angle and orientation of the photovoltaic panel 1 can be adjusted according to the sunlight irradiation angle, maximizing the utilization of sunlight resources.

[0021] In this embodiment, please refer to Figure 4 , a number of baffles 221 are respectively arranged on both sides of the movable column 22. The positioning mechanism 26 includes a cylinder 261 and a locking plate 264. The locking plate 264 is arranged in the inner cavity of the lower foundation pile 21 and is located on both sides of the movable column 22 respectively. A gear 263 is further arranged on one side of the locking plate 264. The cylinder 261 is arranged inside the lower foundation pile 21 and is located at the bottom of the gear 263. A rack 262 is arranged at the output end of the cylinder 261. One side of the rack 262 is meshed with the outer edge of the gear 263. In this embodiment, when the overall length of the fixed pile 2 increases, that is, after the movable column 22 moves upward, the cylinder 261 gives power to push the rack 262 to move upward. Since one side of the rack 262 is meshed with the outer edge of the gear 263, the gear 263 is driven to rotate. The gear 263 rotates to drive the locking plate 264 to rotate upward, making the locking plate 264 tilt upward, so that the locking plate 264 provides resistance to the baffle 221. After the movable column 22 moves upward, its position is locked to maintain the stability of the bracket. When the overall height of the fixed pile 2 needs to be decreased, the cylinder 261 drives the rack 262 to move downward, making the locking plate 264 rotate downward and tilt downward. At this time, the locking plate 264 cannot provide resistance to the baffle 221, so that the movable column 22 can be controlled to move downward.

[0022] In this embodiment, please refer to Figure 2 and Figure 5 . Hinges 27 are provided at the connection ends of the mounting frame 3 and the fixed pile 2, and at the connection ends of the wire rope 4 and the fixed pile 2. The hinge 27 enables a certain range of movement between the mounting frame 3 and the wire rope 4 and the fixed pile 2. In this embodiment, by providing the hinge 27, when the height of the fixed pile 2 changes, a certain amount of movement space is given through the hinge 27, which facilitates the adjustment of the tilt angle of the photovoltaic panel 1, enabling the entire bracket system to better adapt to the complex and changeable terrain and slopes of the mountain, increasing the flexibility and adaptability of the bracket.

[0023] In this embodiment, please refer to Figure 3 and Figure 6 . The top of the threaded shaft 253 is connected to a transmission plate 222. The transmission plate 222 passes through the movable column 22 and its top end is located in the inner cavity of the top cover 24. A wire rope winding roller 241 is provided in the inner cavity of the top cover 24, and a wire rope 4 is wound around the outer side of the wire rope winding roller 241. In this embodiment, the first-generation flexible bracket solves the problems of large span and high clearance. However, since its components are mainly supported by wire ropes, it may be distorted or broken under the action of strong winds, resulting in collisions and hidden cracks in the photovoltaic modules. After the installation of the photovoltaic bracket is completed, by rotating the wire rope winding roller 241, the pre-tightening force of the wire rope 4 can be adjusted. The wire rope 4 will remain in a taut state under the action of tension, which helps to enhance the stability and stiffness of the wire rope 4, enabling it to better resist the action of external dynamic forces such as wind loads. At the same time, the taut wire rope 4 can also reduce the slack and vibration phenomena caused by wind vibration, etc., thereby protecting the overall structural safety of the flexible bracket.

[0024] In this embodiment, please refer to Figure 6 . A rotating shaft 244 is provided on one side of the wire rope winding roller 241. A worm gear 243 that meshes with the transmission plate 222 is also provided in the inner cavity of the top cover 24. By moving the transmission plate 222 up and down, the rotation of the worm gear 243 can be controlled. By controlling the rotation of the worm gear 243, the wire rope winding roller 241 can be driven to rotate. In this embodiment, when the threaded shaft 253 moves up and down, the transmission plate 222 moves up and down accordingly. By moving the transmission plate 222 up and down, the rotation of the worm gear 243 is driven. By the rotation of the worm gear 243, the rotation of the worm 242 is driven. By the worm 242, the wire rope winding roller 241 is driven to rotate, adjusting the pre-tightening force of the wire rope 4, so that while the height of the fixed pile 2 is adjusted, the pre-tightening force of the wire rope 4 is also adjusted accordingly, avoiding the wire rope 4 from being too tight or too loose due to the height change between the fixed piles 2.

[0025] In this embodiment, please refer to Figure 8, the connecting member 33 includes a fixing base 331. An engaging block 332 is arranged in the inner cavity of the fixing base 331. The bottom of the engaging block 332 is arranged as an inclined surface. In this embodiment, when one side of the connecting plate 11 is inserted into the inner cavity of the clamping plate 31, under the action of the inclined surface at the bottom of the engaging block 332, an upward thrust is provided to the engaging block 332. By the upward movement of the engaging block 332, the spring 333 is squeezed to deform. When the connecting hole 111 moves to directly below the engaging block 332, the spring 333 rebounds, so that the engaging block 332 moves downward to return to its original position, and the engaging block 332 enters the inner cavity of the connecting hole 111, thereby fixing the connecting plate 11 in the inner cavity of the clamping plate 31 and installing the photovoltaic panel 1 on one side of the mounting frame 3.

[0026] In this embodiment, please refer to Figures 7-8 , a movable groove 32 is opened at the top of the clamping plate 31. A movable plate 34 is arranged on the inner wall of the movable groove 32. A first magnetic ring 35 is arranged at the bottom of the movable plate 34. The movable plate 34 is fixed in the inner cavity of the movable groove 32 through a bolt 341. A second magnetic ring 334 is arranged at the top of the engaging block 332. The corresponding surfaces of the first magnetic ring 35 and the second magnetic ring 334 attract each other. In this embodiment, by loosening the bolt 341 to make the movable plate 34 movable, the position of the first magnetic ring 35 is adjusted by moving the movable plate 34. When the first magnetic ring 35 is moved directly above the connecting member 33, due to the mutual attraction between the first magnetic ring 35 and the second magnetic ring 334, the engaging block 332 moves upward under the action of the magnetic field, so that it disengages from the inner cavity of the connecting hole 111, and thus the photovoltaic panel 1 can be removed from one side of the mounting frame 3.

[0027] In this embodiment, please refer to Figure 6 , a worm 242 is arranged on the other side of the wire winding roller 241. One end of the worm 242 is movably connected to the inner wall of the top cover 24. The outer edge of the worm gear 243 meshes with the outer edge of the worm 242. In this embodiment, by providing the worm 242, since the characteristic of the worm gear 243 and the worm 242 is that only the worm gear 243 can drive the worm 242 to rotate, the worm 242 cannot drive the worm gear 243 to rotate, so that the worm 242 has a locking effect. Therefore, during use, after the pre-tightening force of the steel wire rope 4 is adjusted, only by adjusting the height of the fixed pile 2 to drive the worm gear 243 to rotate through the transmission plate 222 can the wire winding roller 241 rotate, so that the pre-tightening force of the steel wire rope 4 adapts to the fixed pile 2 after the height adjustment. During use, the pre-tightening force of the steel wire rope 4 will not become loose due to external forces, such as the pressure of the photovoltaic panel 1, causing the wire winding roller 241 to rotate automatically, so that the pre-tightening force of the steel wire rope 4 remains stable, further improving the service life of the steel wire rope 4.

[0028] In this embodiment, please refer to Figure 1 、 Figure 5, an anti-corrosion material is coated on the outer side of the wire rope 4, and buffer pads are respectively arranged on both sides of the connection between the wire rope 4 and the hinge 27. In this embodiment, by coating an anti-corrosion material such as grease on the outer side of the wire rope 4, its weather resistance is improved, effectively isolating the direct contact between air, moisture and other corrosive media and the wire rope 4. At the same time, by arranging buffer pads at the connection between the wire rope 4 and the hinge 27, the vibration energy is absorbed and dissipated, reducing the vibration amplitude and frequency of the wire rope 4, and further improving the strength and service life of the wire rope 4.

[0029] Working principle of the present invention: Step 1: The servo motor 251 is used to give power to control the rotation of the telescopic rod 252. The telescopic rod 252 drives the threaded shaft 253 to rotate, and the threaded shaft 253 rotates along the inner wall of the threaded groove 211. Since the outer side of the threaded shaft 253 and the inner wall of the threaded groove 211 are in threaded cooperation, the rotation direction of the threaded shaft 253 can be controlled, enabling it to move upward along the inner wall of the threaded groove 211. And because the length of the telescopic rod 252 can be telescoped and can transmit torque, when the threaded shaft 253 moves upward, the length of the telescopic rod 252 is stretched. Since the top of the threaded shaft 253 contacts the bottom of the movable column 22, the movable column 22 is pushed upward by the threaded shaft 253. By the upward movement of the movable column 22, the upper foundation pile 23 moves upward. According to the above principle, by controlling the reverse rotation of the upper foundation pile 23, the upper foundation pile 23 can move downward, thereby adjusting the overall height of the fixed pile 2. Construction workers can adjust the height of the fixed pile 2 according to the terrain height difference of the large slope, so that the top of the fixed pile 2 is on the same horizontal plane, facilitating the installation of the photovoltaic panel. At the same time, through the illuminance sensor arranged in the mounting frame 3, according to the detection of the sunlight irradiation direction by the illuminance sensor, the height of the fixed piles 2 in different directions is adjusted according to the direction of the light, so that the inclination angle of the photovoltaic panel 1 changes, and the photovoltaic panel 1 tilts towards the direction of the light, adjusting the photovoltaic panel 1 to the best angle for receiving sunlight, improving the power generation efficiency of the photovoltaic panel 1; Step 2: By controlling the rotation of the rotating shaft 244, drive the wire winding roller 241 to rotate. Since the steel wire rope 4 is wound around the outer side of the wire winding roller 241, by controlling the rotation of the wire winding roller 241, the steel wire rope 4 connecting the two photovoltaic panels 1 is tightened, and the steel wire rope 4 is kept in a taut state under the action of tension, thereby enhancing the stability and stiffness of the steel wire rope 4 and enabling it to better resist the action of dynamic forces such as external wind loads. At the same time, the taut steel wire rope 4 can also reduce the slack and vibration phenomena caused by wind vibration, etc., thereby protecting the overall structural safety of the flexible support. At the same time, when the height of the fixed pile 2 is adjusted, when the threaded shaft 253 moves up and down, drive the transmission plate 222 to move up and down. Since one side of the transmission plate 222 meshes with one side of the worm gear 243, when the transmission plate 222 moves, drive the worm gear 243 to rotate. Since the outer edge of the worm gear 243 meshes with the outer edge of the worm 242, drive the worm 242 to rotate through the rotation of the worm gear 243, and drive the wire winding roller 241 to rotate through the rotation of the worm 242 to adjust the tension of the steel wire rope 4. Thus, according to the height change of the fixed pile 2 and the height difference between adjacent fixed piles 2, the tension of the steel wire rope 4 is also adjusted accordingly, avoiding the problem of the steel wire rope 4 being too loose or too tight due to the height change of the fixed pile 2; Step 3: When installing the photovoltaic panel 1, dock one side of the photovoltaic panel 1 with the mounting frame 3, so that the connecting plate 11 enters the inner cavity of the clamping plate 31, and the top surface of the connecting plate 11 contacts the connecting member 33. Since the bottom of the fitting block 332 is provided with an inclined surface, when the connecting plate 11 enters the clamping plate 31, under the action of the inclined surface, the fitting block 332 is pushed to move upward, and the spring 333 is compressed and deformed by the upward movement of the fitting block 332. As the position of the connecting plate 11 moves, when the connecting hole 111 moves to directly below the fitting block 332, the spring 333 rebounds without pressure, thereby pushing up the fitting block 332 to move downward, so that the fitting block 332 enters the inner cavity of the connecting hole 111, thereby fixing the connecting plate 11 in the clamping plate 31. Dock both sides of the photovoltaic panel 1 with the two mounting frames 3 respectively, so that the photovoltaic panel 1 is fixed above the support. When disassembling, loosen the bolt 341 and move the movable plate 34 until the first magnetic ring 35 moves directly above the connecting member 33. Since the corresponding surfaces of the first magnetic ring 35 and the second magnetic ring 334 attract each other, under the attraction of the first magnetic ring 35, the fitting block 332 moves upward, and the fitting block 332 moves upward to leave the inner cavity of the connecting hole 111, disconnecting the connection between the photovoltaic panel 1 and the mounting frame 3, and the photovoltaic panel 1 can be removed from the top of the support.
