Description

Technical Field

[0001] This invention belongs to the field of photovoltaic installation technology, specifically a spiral ground pile type adjustable photovoltaic support. Background Technology

[0002] Solar energy resources are abundant and widely distributed, making it the most promising renewable energy source. With global energy shortages and environmental pollution becoming increasingly prominent, solar photovoltaic (PV) power generation, due to its cleanliness, safety, convenience, and high efficiency, is a major future trend. Utilizing solar PV technology to create clean and renewable energy for humanity has become a new energy industry of widespread concern and key development for countries worldwide.

[0003] Specifically, the commonly used helical ground pile adjustable photovoltaic brackets on the market currently have the following shortcomings:

[0004] A. Currently, many photovoltaic support structures lack buffer devices to absorb the energy when facing wind impacts. The structures can only rely on their own structural strength to resist the impact, making it difficult to effectively control the swaying amplitude and speed of the structures, thus increasing the risk of structural damage.

[0005] B. When facing lateral forces, existing photovoltaic (PV) support structures lack the ability to make appropriate adjustments. As a result, in complex environments with varying wind speeds and directions, the PV support structures cannot flexibly adapt to changes in external forces, leaving them in a relatively passive stress state. This easily leads to stress accumulation, which in turn affects the structural integrity and service life of the entire PV support structure. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides a spiral ground pile type adjustable photovoltaic support to at least partially solve the above technical problems.

[0007] The technical solution adopted in this invention is as follows:

[0008] This invention proposes a spiral ground-pillar type adjustable photovoltaic support, comprising: a fixed frame, wherein two sets of fixed frames are provided, a support frame is provided between the two sets of fixed frames, an optical fiber energy storage plate is provided above the support frame, a wind-resistant limiting block is provided inside the fixed frame, and the other side of the wind-resistant limiting block is provided on the outer wall of the support frame; and a mounting frame plate, wherein the mounting frame plate is provided below the support frame, a wind-resistant connecting block is provided inside the mounting frame plate, the bottom surface of the support frame is fixedly connected to the top surface of the wind-resistant connecting block, and the support frame slides inside the mounting frame plate through the wind-resistant connecting block.

[0009] In one embodiment of the present invention, the spiral ground pile type adjustable photovoltaic bracket further includes: a support base frame, the support base frame having fixing grooves on both sides, a fixing frame disposed inside the fixing grooves, an mounting frame plate disposed on the top surface of the inner cavity of the support base frame, and a support frame body disposed in the inner cavity of the support base frame.

[0010] In one embodiment of the present invention, buffer damping rods are provided on both sides of the wind-resistant limiting block, and one end of the buffer damping rod is provided on the inner wall of the fixed frame.

[0011] In one embodiment of the present invention, L-shaped fixing rods are provided on both sides of the outer wall of the fixing frame, and offset sensors are provided inside the L-shaped fixing rods. Contact rods adapted to the size of the L-shaped fixing rods are provided on both sides of the outer wall of the wind-resistant limiting block.

[0012] In one embodiment of the present invention, the wind-resistant connecting block is provided with spiral buffer rods on both sides, and the other end of the spiral buffer rods is provided on the inner wall of the mounting frame plate.

[0013] In one embodiment of the present invention, limiting plates are provided on both sides of the outer wall of the mounting frame plate, and four sets of limiting plates are provided. A first magnetic plate is provided inside the four sets of limiting plates. A side fixing plate is provided in the middle of the outer wall of the mounting frame plate. A second magnetic plate adapted to the first magnetic plate is provided on both sides of the side fixing plate. A sliding connecting rod is provided in the middle of the outer wall of the side fixing plate, and the other end of the sliding connecting rod is provided on the outside of the wind-resistant connecting block.

[0014] In one embodiment of the present invention, the top surface of the support frame is provided with a concave positioning plate, and there are four sets of the concave positioning plates. The four sets of the concave positioning plates are fixedly connected to the top surface of the support frame, and the optical fiber energy storage plate is provided on the top surface of the concave positioning plate.

[0015] In one embodiment of the present invention, the concave positioning plate has a through hole inside, and a rotating shaft is provided inside the through hole. The rotating shaft passes through the interior of the optical fiber energy storage plate, and the optical fiber energy storage plate rotates on the top surface of the support frame.

[0016] In one embodiment of the present invention, the supporting base is configured as a rectangular frame structure, and spiral bottom piles are provided at the four corners of the bottom surface of the supporting base, and the bottom surfaces of the four sets of spiral bottom piles are provided with matching fixed spiral heads.

[0017] In one embodiment of the present invention, the surface of the mounting frame plate is provided with a plurality of ventilation holes.

[0018] The beneficial effects of the technical solution of this invention are as follows:

[0019] By using wind-resistant limiting blocks and buffer damping rods, the wind-resistant limiting blocks can prevent the support frame from swaying or shifting excessively when facing lateral forces such as wind, thereby ensuring the integrity of the overall photovoltaic support structure and reducing the risk of damage caused by structural instability. When encountering strong winds, the impact force of the wind on the photovoltaic support frame will cause the support frame to sway to some extent. At this time, the buffer damping rods can absorb some energy and reduce the amplitude and speed of the swaying.

[0020] By using wind-resistant connecting blocks and mounting frames, when subjected to lateral wind forces, the wind-resistant connecting blocks can make appropriate sliding adjustments within the mounting frames, preventing the overall structure of the support from suffering excessive stress damage due to rigid connections, thereby enhancing the stability of the entire photovoltaic support structure in complex environments.

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following describes an embodiment of the present invention, a spiral ground pile type adjustable photovoltaic support, with reference to the accompanying drawings.

[0035] like Figures 1 to 9 As shown, this embodiment of the invention provides a spiral ground pile type adjustable photovoltaic support, a support base 1, a fixing groove 4 is provided on both sides of the support base 1, a fixing frame 5 is provided inside the fixing groove 4, a mounting frame plate 11 is provided on the top surface of the inner cavity of the support base 1, and a support frame body 13 is provided in the inner cavity of the support base 1; the fixing frame 5 is provided in two sets, and the support frame body 13 is provided between the two sets of fixing frames 5. An optical fiber energy storage plate 22 is provided above the support frame body 13. A wind-resistant limiting block 6 is provided inside the fixing frame 5, and the other side of the wind-resistant limiting block 6 is provided on the outer wall of the support frame body 13; buffer damping rods 7 are provided on both sides of the wind-resistant limiting block 6, one end of the buffer damping rod 7 is provided on the inner wall of the fixing frame 5, and L-shaped fixing rods 8 are provided on both sides of the outer wall of the fixing frame 5. An offset sensor 9 is provided inside the L-shaped fixing rod 8, and contact rods 10 adapted to the size of the L-shaped fixing rod 8 are provided on both sides of the outer wall of the wind-resistant limiting block 6.

[0036] In practical application, the wind-resistant limiting block is in a relatively stable state within the fixed frame 5, limiting the support frame 13 and preventing excessive horizontal movement. When wind blows towards the photovoltaic support, the lateral force generated by the wind on the fiber optic energy storage panel 22 is transmitted to the wind-resistant limiting block through the support frame 13. The support frame 13, under the influence of wind, will tend to displace. At this time, the wind-resistant limiting block prevents excessive displacement of the support frame 13. The buffer damping rods 7 on both sides of the wind-resistant limiting block begin to work. One end of the buffer damping rod 7 is fixed to the inner wall of the fixed frame 5. When the wind-resistant limiting block is subjected to lateral force and tends to move, the buffer damping rod 7 will be compressed or stretched, absorbing and dissipating energy according to its damping characteristics, thereby reducing the movement amplitude of the wind-resistant limiting block and limiting the sway amplitude of the support frame 13.

[0037] If the wind is strong, the displacement of the support frame 13 may cause the contact rod 10 on the outer wall of the wind-resistant limiting block to come into contact with the L-shaped fixing rod 8. The offset sensor 9 inside the L-shaped fixing rod 8 will sense this contact and detect the offset of the support frame 13, thereby providing timely feedback on the status information of the photovoltaic bracket under the action of wind, so that further reinforcement or adjustment measures can be taken when necessary.

[0038] In one possible implementation, a mounting frame 11 is installed below the support frame 13. A wind-resistant connecting block 12 is provided inside the mounting frame 11. The bottom surface of the support frame 13 is fixedly connected to the top surface of the wind-resistant connecting block 12. The support frame 13 slides inside the mounting frame 11 via the wind-resistant connecting block 12. Spiral buffer rods 14 are provided on both sides of the wind-resistant connecting block 12, with the other end of each spiral buffer rod 14 located on the inner wall of the mounting frame 11. Limiting plates 15 are provided on both sides of the outer wall of the mounting frame 11, with four sets of limiting plates 15. A first magnetic plate 16 is provided inside each of the four sets of limiting plates 15. A side fixing plate 18 is provided in the middle of the outer wall of the mounting frame 11. Second magnetic plates 17, adapted to the first magnetic plate 16, are provided on both sides of the side fixing plate 18. A sliding connecting rod 19 is provided in the middle of the outer wall of the side fixing plate 18, with the other end of the sliding connecting rod 19 located on the outer side of the wind-resistant connecting block 12.

[0039] In a specific application of this invention, when the photovoltaic support is subjected to external forces such as wind, the force first acts on the support frame 13. Since the support frame 13 is fixedly connected to the wind-resistant connecting block 12, the force is transmitted to the wind-resistant connecting block 12. The wind-resistant connecting block 12 slides inside the mounting frame plate 11. At this time, the spiral buffer rod 14 will undergo elastic deformation due to the sliding of the wind-resistant connecting block 12. The spiral structure of the spiral buffer rod 14 can convert the external force into elastic potential energy and store it, thereby buffering part of the external force.

[0040] Meanwhile, the magnetic interaction between the limiting plate 15 and the first magnetic plate 16 inside it, and the second magnetic plate 17 on the side fixing plate 18, will generate a certain resistance to the sliding of the wind-resistant connecting block 12. This resistance can prevent the wind-resistant connecting block 12 from sliding excessively, ensuring that the entire structure is adjusted under stress within the normal working range. If the position of the wind-resistant connecting block 12 needs to be adjusted, the magnetic connection can be released first, and then the side fixing plate 18 can be moved. The side fixing plate 18 will drive the wind-resistant connecting block 12 to slide to a suitable position inside the mounting frame plate 11 through the sliding connecting rod 19. Finally, the magnetic connection can be re-established to fix the relative position of the limiting plate 15 and the side fixing plate 18, thereby completing the adjustment of the support structure.

[0041] In strong wind conditions, the wind force generates complex stress on the photovoltaic support. The sliding of the wind-resistant connecting block 12 within the mounting frame 11, the elastic deformation of the spiral buffer rod 14, and the limiting and stabilizing between the limiting plate 15 and the magnetic plate work together to disperse and absorb the stress generated by the wind. The side fixing plate 18 and the sliding connecting rod 19 maintain the overall structural stability while also being able to be adjusted appropriately according to the magnitude and direction of the wind force, ensuring that the entire photovoltaic support can stably withstand the wind force, protect the photovoltaic modules from damage, and ensure their normal power generation.

[0042] In one possible implementation, the top surface of the support frame 13 is provided with a concave positioning plate 23, and there are four sets of concave positioning plates 23. The four sets of concave positioning plates 23 are fixedly connected to the top surface of the support frame 13. The fiber optic energy storage plate 22 is provided on the top surface of the concave positioning plate 23. The concave positioning plate 23 has a through hole 20 inside, and a rotating shaft 24 is provided inside the through hole 20. The rotating shaft 24 passes through the inside of the fiber optic energy storage plate 22, and the fiber optic energy storage plate 22 rotates on the top surface of the support frame 13.

[0043] In a specific application of this embodiment of the invention, four sets of concave positioning plates 23 are fixed to the top surface of the support frame 13. A rotating shaft 24 is inserted into the through-hole 20 of the concave positioning plates 23, preparing for the subsequent installation of the fiber optic energy storage board 22. The fiber optic energy storage board 22 is placed on the top surface of the concave positioning plates 23, with the rotating shaft 24 penetrating the interior of the fiber optic energy storage board 22. Thus, the fiber optic energy storage board 22 is positioned on the top surface of the support frame 13 and can rotate around the rotating shaft 24.

[0044] Based on the illumination conditions determined by the light sensor or by manual judgment, when it is necessary to adjust the angle of the fiber optic energy storage plate 22, it can be rotated manually or by an electric device (if equipped). Due to the presence of the rotation shaft 24, the fiber optic energy storage plate 22 can rotate smoothly on the top surface of the concave positioning plate 23.

[0045] During rotation, the concave structure of the concave positioning plate 23 and the rotating shaft 24 constrain and support the fiber optic energy storage plate 22, ensuring its rotation accuracy and stability. After being adjusted to a suitable angle, the fiber optic energy storage plate 22 can receive sunlight in the optimal posture, converting light energy into electrical energy and storing it.

[0046] When the angle of the fiber optic energy storage panel 22 needs to be adjusted, an external force is applied to the fiber optic energy storage panel 22 with the rotation shaft 24 as the center. Since the rotation shaft 24 is located inside the through hole 20 of the concave positioning plate 23 and passes through the fiber optic energy storage panel 22, the fiber optic energy storage panel 22 can rotate on the top surface of the support frame 13. According to the real-time sunlight conditions, the fiber optic energy storage panel 22 can be rotated to the optimal light-receiving angle to ensure that solar energy can be efficiently converted into electrical energy and stored under different sunlight conditions (assuming that the fiber optic energy storage panel 22 has an energy storage function).

[0047] In one possible implementation, the support base 1 is configured as a rectangular frame structure, and spiral bottom piles 2 are provided at the four corners of the bottom surface of the support base 1. The bottom surface of the four sets of spiral bottom piles 2 is provided with matching fixed spiral heads 3, and several sets of ventilation holes 21 are opened on the surface of the mounting frame plate 11.

[0048] In specific applications of this invention, during installation, the helical ground-piled photovoltaic support system is first transported to the designated installation location. Then, using specific equipment (such as a screw-in machine), the helical base piles 2 are screwed into the ground. Due to the fixed helical head 3 on the bottom surface of the helical base pile 2, the helical head cuts into the soil during the screwing process. As the helical base pile 2 is continuously screwed in, the soil exerts significant lateral pressure on the helical head, thereby firmly fixing the helical base pile 2 underground. The supporting frame 1 is stably supported on the ground by the four helical base piles 2.

[0049] The sun's altitude angle varies depending on the season and time of day. By adjusting the tilt angle of photovoltaic panels, they can be kept relatively perpendicular to sunlight, optimizing solar energy collection.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0051] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
