Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic installation, and in particular is a spiral ground pile type adjustable photovoltaic support. Background Art

[0002] Solar energy resources are abundant and widely distributed, and it is the renewable energy with the greatest development potential. As global energy shortages and environmental pollution become increasingly prominent, solar photovoltaic power generation is clean, safe, convenient, and efficient. Using solar photovoltaic power generation technology to create clean renewable energy for mankind is a major trend in the future and has become an emerging energy industry that is widely concerned and focused on by countries around the world.

[0003] Specifically, the common spiral ground pile adjustable photovoltaic brackets on the market currently have the following shortcomings:

[0004] A. Currently, when dealing with wind impact, many photovoltaic brackets have no buffer devices to absorb this part of energy. The brackets can only rely entirely on the strength of their own structure to resist it, making it difficult to effectively control the swing amplitude and speed of the brackets, increasing the risk of structural damage.

[0005] B. When facing lateral forces, the existing photovoltaic brackets lack structures that can be adjusted appropriately. As a result, in complex environments with different wind strengths and directions, the photovoltaic brackets cannot flexibly adapt to changes in external forces, causing the brackets to always be in a relatively passive stress state, which is prone to stress accumulation, thus affecting the structural integrity and service life of the entire photovoltaic bracket. Summary of the invention

[0006] In view of the above situation, in order 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 by the present invention is as follows:

[0008] The present invention proposes a spiral ground pile type adjustable photovoltaic bracket, comprising: a fixing frame, wherein the fixing frame is provided with two groups, a supporting frame body is provided between the two groups of the fixing frames, a fiber optic energy storage plate is provided above the supporting frame body, a wind-resistant limit block is provided inside the fixing frame, and the other side of the wind-resistant limit block is provided on the outer wall of the supporting frame body; an installing frame plate, wherein the installing frame plate is provided below the supporting frame body, a wind-resistant connecting block is provided inside the installing frame plate, the bottom surface of the supporting frame body is fixedly connected to the top surface of the wind-resistant connecting block, and the supporting frame body slides inside the installing frame plate through the wind-resistant connecting block.

[0009] In one embodiment of the present invention, the spiral ground pile type adjustable photovoltaic bracket also includes: a supporting base frame, wherein fixing grooves are opened on both sides of the supporting base frame, the fixing frame is arranged inside the fixing grooves, the mounting frame plate is arranged on the top surface of the inner cavity of the supporting base frame, and the supporting frame body is arranged in the inner cavity of the supporting base frame.

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

[0012] In one embodiment of the present invention, spiral buffer rods are provided on both sides of the wind-resistant connection block, and the other end of the spiral buffer rod is provided on the inner wall of the installation 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 the limiting plates are provided in four groups. A first magnetic plate is provided inside the four groups of limiting plates, and an edge fixing plate is provided in the middle of the outer wall of the mounting frame plate. Second magnetic plates compatible with the first magnetic plate are provided on both sides of the edge fixing plate, and a sliding connecting rod is provided in the middle of the outer wall of the edge 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 the concave positioning plates are provided with four groups.

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

[0018] The beneficial effects of the technical solution of the present invention are:

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

[0034] A spiral ground pile type adjustable photovoltaic support according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

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

[0036] In the specific application of the embodiment of the present invention, the wind-resistant limit block is in a relatively stable state in the fixed frame 5, and plays a limiting role on the support frame 13 to prevent it from excessively moving in the horizontal direction. When the wind blows towards the photovoltaic bracket, the lateral force generated by the wind on the optical fiber energy storage board 22 will be transmitted to the wind-resistant limit block through the support frame 13. After the support frame 13 is affected by the wind, it will have a displacement tendency. At this time, the wind-resistant limit block will prevent the excessive displacement of the support frame 13, and the buffer damping rods 7 on both sides of the wind-resistant limit block will start 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 limit block is subjected to lateral force and has a tendency 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 limit block, and further limiting the shaking 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 limit block to contact the L-shaped fixing rod 8. The offset sensor 9 inside the L-shaped fixing rod 8 will sense this contact, thereby detecting the offset of the support frame 13, thereby timely feedback of 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 a possible embodiment, an installation frame plate 11 is arranged below the supporting frame body 13, a wind-resistant connecting block 12 is arranged inside the installation frame plate 11, the bottom surface of the supporting frame body 13 is fixedly connected to the top surface of the wind-resistant connecting block 12, and the supporting frame body 13 slides inside the installation frame plate 11 through the wind-resistant connecting block 12; spiral buffer rods 14 are arranged on both sides of the wind-resistant connecting block 12, and the other end of the spiral buffer rods 14 is arranged on the inner wall of the installation frame plate 11; limit plates 15 are arranged on both sides of the outer wall of the installation frame plate 11, and four groups of limit plates 15 are arranged inside the four groups of limit plates 15; an edge fixing plate 18 is arranged in the middle of the outer wall of the installation frame plate 11, and second magnetic plates 17 matched with the first magnetic plate 16 are arranged on both sides of the edge fixing plate 18; a sliding connecting rod 19 is arranged in the middle of the outer wall of the edge fixing plate 18, and the other end of the sliding connecting rod 19 is arranged on the outer side of the wind-resistant connecting block 12.

[0039] In a specific application of the embodiment of the present invention, when the photovoltaic bracket 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 will be transmitted to the wind-resistant connecting block 12. The wind-resistant connecting block 12 slides inside the mounting frame 11. At this time, the spiral buffer rod 14 will be elastically deformed 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] At the same time, the magnetic interaction between the limit plate 15 and the first magnetic plate 16 inside it and the second magnetic plate 17 on the edge fixing plate 18 will produce a certain resistance to the sliding of the wind-resistant connection block 12, and the resistance can prevent the wind-resistant connection block 12 from sliding excessively, ensuring that the entire structure is adjusted within the normal working range. If the position of the wind-resistant connection block 12 is to be adjusted, the magnetic connection can be released first, and then the edge fixing plate 18 can be moved. The edge fixing plate 18 drives the wind-resistant connection block 12 to slide to a suitable position inside the installation frame plate 11 through the sliding connecting rod 19, and finally the magnetic connection is re-established to fix the relative position of the limit plate 15 and the edge fixing plate 18, thereby completing the adjustment of the bracket structure.

[0041] In a strong wind environment, the wind creates complex stresses on the photovoltaic bracket. The sliding of the wind-resistant connecting block 12 in the mounting frame 11, the elastic deformation of the spiral buffer rod 14, and the limitation and stability between the limit plate 15 and the magnetic plate work together to disperse and absorb the stresses generated by the wind. The edge fixing plate 18 and the sliding connecting rod 19 can be appropriately adjusted according to the size and direction of the wind while maintaining the stability of the overall structure, ensuring that the entire photovoltaic bracket can stably withstand the wind, protect the photovoltaic components from damage and ensure their normal power generation.

[0042] In a possible embodiment, a concave positioning plate 23 is provided on the top surface of the support frame 13, and four groups of concave positioning plates 23 are provided. The four groups of concave positioning plates 23 are fixedly connected to the top surface of the support frame 13, and the optical fiber energy storage plate 22 is provided on the top surface of the concave positioning plate 23; a through hole 20 is opened inside the concave positioning plate 23, and a rotating shaft 24 is provided inside the through hole 20. The rotating shaft 24 passes through the interior of the optical fiber energy storage plate 22, and the optical fiber energy storage plate 22 rotates on the top surface of the support frame 13.

[0043] In a specific application of the embodiment of the present invention, four groups of concave positioning plates 23 are fixed on the top surface of the support frame 13, and the rotation shaft 24 is inserted into the through hole 20 of the concave positioning plate 23, so as to prepare for the subsequent installation of the optical fiber energy storage plate 22. The optical fiber energy storage plate 22 is placed on the top surface of the concave positioning plate 23, and the rotation shaft 24 passes through the inside of the optical fiber energy storage plate 22, so that the optical fiber energy storage plate 22 is positioned on the top surface of the support frame 13, and can rotate around the rotation shaft 24.

[0044] According to the illumination conditions determined by the illumination sensor or manually, when the angle of the optical fiber energy storage board 22 needs to be adjusted, the optical fiber energy storage board 22 can be rotated manually or by an electric device (if equipped). Due to the existence of the rotating shaft 24, the optical fiber energy storage board 22 can rotate smoothly on the top surface of the concave positioning plate 23.

[0045] During the rotation process, the concave structure of the concave positioning plate 23 and the rotating shaft 24 constrain and support the optical fiber energy storage plate 22, ensuring the accuracy and stability of its rotation. After adjusting to a suitable angle, the optical fiber energy storage plate 22 can receive sunlight in the best posture, convert light energy into electrical energy and store it.

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

[0047] In a possible embodiment, the supporting frame 1 is configured as a rectangular frame structure, spiral bottom piles 2 are provided at the four corners of the bottom surface of the supporting frame 1, the bottom surfaces of the four groups of spiral bottom piles 2 are provided with corresponding fixed spiral heads 3, and the surface of the mounting frame plate 11 is provided with a plurality of groups of ventilation holes 21.

[0048] In a specific application of the embodiment of the present invention, during the installation process, the spiral ground pile type photovoltaic support is first transported to the predetermined installation site. Then, the spiral bottom pile column 2 is screwed into the ground through a specific device (such as a screw-in machine, etc.). Due to the fixed spiral head 3 on the bottom surface of the spiral bottom pile column 2, the spiral head will cut into the soil during the screwing process. As the spiral bottom pile column 2 is continuously screwed in, the soil will produce a large lateral pressure on the spiral head, thereby firmly fixing the spiral bottom pile column 2 underground. The support frame 1 is stably supported on the ground by the fixation of the four spiral bottom pile columns 2.

[0049] The sun's altitude angle changes in different seasons or time periods. By adjusting the tilt angle of the photovoltaic panels, the panels can always remain relatively perpendicular to the sun's rays, optimizing the solar energy collection effect.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0051] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
