Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a flexible photovoltaic support with adjustable angle and wind resistance and vibration reduction. Background Technology

[0002] Flexible photovoltaic (PV) supports play a crucial role in photovoltaic (PV) power generation. Their design not only addresses some of the challenges faced by traditional fixed supports but also provides new pathways to improve power generation efficiency and achieve sustainable development. By employing prestressed cable systems, flexible PV supports can achieve large-span support, adapting to various complex terrain conditions, such as mountains, water surfaces, and other irregular surfaces. This flexibility means that PV power plant construction is no longer limited to flat, open land, greatly expanding the range of available resources. Furthermore, because a wider coverage area can be created, the number of PV panels installed per unit area can be increased, thereby improving overall power generation. In addition, it allows for other activities beneath the solar panels, such as agricultural planting or aquaculture, promoting multi-level utilization of land resources and achieving a win-win situation for both economic and ecological benefits.

[0003] However, existing flexible photovoltaic (PV) supports suffer from problems such as weak wind vibration resistance and inability to adjust their angle. Specifically:

[0004] 1. Lack of angle adjustment function: Flexible photovoltaic brackets are usually made of flexible materials. These materials do not have enough rigidity and stability to support the angle adjustment mechanism, resulting in a fixed structure that cannot adapt to different solar angles or optimize the receiving angle of photovoltaic modules.

[0005] 2. Weak wind vibration resistance: The existing flexible photovoltaic support structure design has not fully considered the requirements for wind vibration resistance, and the installation method is not firm or stable enough. It cannot withstand the impact and vibration brought by strong winds, which may lead to its destruction in strong wind environments. Utility Model Content

[0006] To address the shortcomings of existing flexible photovoltaic supports, such as the inability to adjust the angle and weak wind resistance, this invention provides a flexible photovoltaic support that is adjustable in angle and has a stable and reliable structure.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An adjustable-angle, wind-resistant, and vibration-damping flexible photovoltaic support includes photovoltaic panels, steel strands, a support frame, and a vibration damping mechanism. The supports are arranged in rows, with n supports per row, where n is an integer and n≥4. Each row has a corresponding steel strand between adjacent supports, with both ends of the steel strand connected to the opposite support. The steel strands are arranged in columns and form a well-shaped support frame with the rows of supports. The photovoltaic panels are arranged in several rows, with several panels per row, and are evenly installed on top of the well-shaped support frame. The vibration damping mechanism includes damping components, connecting components, and an angle adjustment component. The number of damping components matches the number of columns of steel strands. Each damping component is fixedly connected at its top to the middle of the corresponding column of steel strands and its bottom is rotatably hinged to the connecting component. The angle adjustment component includes two symmetrically mounted fixing members below the connecting component, each fixing member being movably connected to the connecting component. One fixing member has an adjuster fixedly mounted on it that cooperates with the connecting component.

[0009] Furthermore, the connecting component is a steel tie rod, which is movably connected to the fixing component, and the steel tie rod is provided with an ear plate. The bottom of the vibration damping component is rotatably connected to the ear plate. The adjuster is an electric push rod, which is fixedly installed on the fixing component, and the middle part of its movable rod is fixedly connected to the end of the steel tie rod. When angle adjustment is required, the electric push rod is driven to extend or retract, which simultaneously moves the steel tie rod. Then, the steel tie rod drives the vibration damping component, thereby tilting the photovoltaic panel. Simply extending or retracting the electric push rod moves the steel tie rod, which in turn pulls the photovoltaic panel to tilt through the vibration damping component. This not only allows for more precise and flexible adjustment of the photovoltaic panel angle to adapt to changes in the angle of sunlight incidence at different times and improves photoelectric conversion efficiency, but also enhances the stability and wind resistance of the entire support system, reducing the risk of damage caused by strong winds.

[0010] Furthermore, the connecting component is a steel pipe, which is movably connected to the fixing component, and the steel pipe is provided with an ear plate. The bottom of the vibration damping component is rotatably connected to the ear plate. The adjuster is an electric push rod, which is fixedly installed on the fixing component, and the middle of its movable rod is fixedly connected to the end of the steel pipe. When angle adjustment is required, the electric push rod is driven to extend or retract, which simultaneously moves the steel pipe. Then, the steel pipe drives the vibration damping component, thereby tilting the photovoltaic panel. Driving the electric push rod to extend or retract moves the steel pipe, realizing the tilt adjustment of the photovoltaic panel. This not only allows for more precise and flexible adjustment of the photovoltaic panel angle to adapt to changes in the solar incidence angle at different times and improves photoelectric conversion efficiency, but also enhances the stability and wind resistance of the entire support system, reducing the risk of damage caused by strong winds. At the same time, the hollow structure of the steel pipe reduces processing costs and facilitates widespread use.

[0011] Furthermore, the connecting component is a flexible cable, on which several ear plates corresponding to the vibration damping components are fixedly installed, and the vibration damping components are rotatably connected to the ear plates. The adjuster is a geared motor, which is fixedly installed on one of the fixing components, and a winding wheel is also provided on the shaft of the geared motor. The two ends of the flexible cable can be movably passed through the fixing components, and then the two ends of the flexible cable are fixedly connected to the upper and lower ends of the winding wheel, respectively. When the winding wheel rotates clockwise or counterclockwise, it drives the ear plates on the flexible cable to move away from or towards the geared motor. When angle adjustment is required, the geared motor is controlled to drive the winding wheel to rotate clockwise or counterclockwise. At this time, the flexible cable is wound clockwise or counterclockwise onto the winding wheel. During this process, the ear plates on the flexible cable move away from or towards the geared motor. The ear plates cooperate with the vibration damping components to pull the vibration damping components to shift, thereby driving the photovoltaic panel to move and achieve angle adjustment. The flexible cable can better adapt to the installation requirements under different terrain conditions, while also reducing material costs and maintenance difficulty. In addition, the method of using a geared motor to drive the winding wheel realizes the automation and remote control of the photovoltaic panel angle, greatly improving the convenience and efficiency of operation.

[0012] Furthermore, the vibration damping component includes threaded steel bars and vibration damping rubber; a cable clamp is installed at the top of the threaded steel bar, and a connecting fork is installed at the bottom; vibration damping rubber is installed in the middle of the cable clamp, and the steel strand passes through the vibration damping rubber and is fixed by the cable clamp; a pin is provided on the connecting fork, and the connecting fork is rotatably connected to the ear plate through the pin. The vibration damping rubber absorbs and disperses vibration energy when vibration occurs. When external force acts on the flexible photovoltaic support, the steel strand is transmitted to the cable clamp through the vibration damping rubber. The vibration damping rubber, with its good elastic properties, can effectively absorb and buffer vibration energy, reduce the impact on the support system, and enhance the stability and safety of the system. The connecting fork is connected to the ear plate through the pin, allowing a certain degree of rotational freedom, which helps maintain the stability of the support under the action of forces in different directions. Furthermore, when it is necessary to adjust the angle of the photovoltaic panel, the adjusting mechanism of the angle adjustment component can be controlled to move the connecting component, which in turn pulls the vibration damping component to offset, facilitating the angle adjustment of the photovoltaic panel.

[0013] How to use this utility model:

[0014] The wind resistance and vibration reduction principle involves connecting several rows of steel strands into a single unit via a vibration reduction mechanism, thereby significantly improving the wind resistance and vibration reduction performance of the flexible photovoltaic support system. During installation, the number of rows formed by the n supports can be set according to actual needs, but at least two rows are required. In use, the vibration reduction component connects to several steel strands, dispersing and reducing vibrations caused by external forces such as wind. Simultaneously, the connecting component connects several steel strands into a single unit, altering the original natural frequency of the steel strands and effectively preventing resonance, thus improving the wind resistance of the flexible photovoltaic support system. When angle adjustment is required, the regulator is activated, controlling the connecting component to move along the fixed component. This movement of the connecting component drives the vibration reduction component, which in turn pulls the steel strands, causing the photovoltaic panel to tilt, thereby achieving angle adjustment.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] 1. This utility model introduces a vibration damping mechanism and an angle adjustment component, solving the problems of existing flexible photovoltaic supports being unable to adjust their angle and having weak wind resistance. The photovoltaic panels can adjust their angle according to the changes in the sun's position, thereby optimizing the light energy absorption efficiency. At the same time, through the connection between the vibration damping component and the steel strand, vibrations caused by external factors (such as wind) are effectively dispersed and reduced, improving the stability of the entire system. By changing the natural frequency of the original steel strand, resonance is avoided, enhancing the durability and safety of the flexible photovoltaic support under strong wind conditions, resulting in good performance.

[0017] 2. The connecting component of this utility model is a steel tie rod, which can be a steel tie rod, steel pipe, or flexible cable. The adjuster is an electric push rod and a geared motor corresponding to its components, which allows the photovoltaic support to be installed as needed and is applicable to different usage scenarios, making it easy to promote. The vibration damping rubber of the vibration damping component is used to absorb and disperse vibration energy when vibration occurs. When external force is applied to the flexible photovoltaic support, the steel strands are transmitted to the cable clamps through the vibration damping rubber. The vibration damping rubber exerts its good elastic properties, which can effectively absorb and buffer vibration energy, reduce the impact on the support system, and enhance the stability and safety of the system.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1: A flexible photovoltaic support structure with adjustable angle and wind resistance and vibration reduction includes photovoltaic panels 1, steel strands 2, supports 3, and vibration reduction mechanism 4; the supports 3 are arranged in rows, with n supports 3 in each row, where n is an integer and n≥4, and there is a corresponding steel strand 2 between adjacent supports 3 in each row, and the two ends of the steel strand 2 are respectively connected to the opposite supports 3, and the steel strands 2 are arranged in columns and form a well-shaped support frame with the rows of supports 3; the photovoltaic panels 1 are arranged in several rows, with several panels in each row, and the several photovoltaic panels 1 are evenly installed on the top of the well-shaped support frame; The vibration damping mechanism 4 includes a vibration damping component 41, a connecting component 42, and an angle adjustment component 43. The number of vibration damping components 41 is the same as the number of columns of steel strands 2. The top of each vibration damping component 41 is fixedly connected to the middle of the corresponding column of steel strands 2, and the bottom is rotatably hinged to the connecting component 42. The angle adjustment component 43 includes two fixing parts 431 symmetrically installed below the connecting component 42. The two fixing parts 431 are movably connected to the connecting component 42. An adjuster 44 that cooperates with the connecting component 42 is fixedly installed on one of the fixing parts 431.

[0027] The wind resistance and vibration reduction principle is achieved by connecting several rows of steel strands 2 into a whole through the vibration reduction mechanism 4, thereby significantly improving the wind resistance and vibration reduction performance of the flexible photovoltaic support. During installation, the number of rows formed by n supports 3 can be set according to actual needs, but must be at least two rows. In use, the vibration reduction component 41 connects to several steel strands 2, dispersing and reducing vibrations caused by external forces, such as wind. Simultaneously, the connecting component 42 connects several steel strands 2 into a whole, changing the original natural frequency of the steel strands 2, effectively preventing resonance and improving the wind resistance performance of the flexible photovoltaic support 3. When angle adjustment is required, the regulator 44 is activated, controlling the connecting component 42 to move along the fixing member 431. During the movement of the connecting component 42, the vibration reduction component 41 is driven, which in turn pulls the steel strands 2 to move. This movement of the steel strands then tilts the photovoltaic panel 1, thus achieving angle adjustment of the photovoltaic panel 1.

[0028] Example 2: Unlike Example 1, the connecting component 42 is a steel tie rod, movably connected to the fixing component 431, and has an ear plate 45. The bottom of the vibration damping component 41 is rotatably connected to the ear plate 45. The adjuster 44 is an electric push rod 441, fixedly mounted on the fixing component 431, with the middle of its movable rod fixedly connected to the end of the steel tie rod. When angle adjustment is needed, the electric push rod 441 is driven to extend or retract, simultaneously moving the steel tie rod. The steel tie rod then drives the vibration damping component 41, thereby tilting the photovoltaic panel 1. Simply extending or retracting the electric push rod moves the steel tie rod, which in turn pulls the photovoltaic panel 1 to tilt via the vibration damping component 41. This not only allows for more precise and flexible adjustment of the photovoltaic panel 1's angle, adapting to changes in the solar incidence angle at different times and improving photoelectric conversion efficiency, but also enhances the stability and wind resistance of the entire support system 3, reducing the risk of damage caused by strong winds.

[0029] Example 3: Unlike Example 1, the connecting component 42 is a steel pipe, movably connected to the fixing component 431, and has an ear plate 45. The bottom of the vibration damping component 41 is rotatably connected to the ear plate 45. The adjuster 44 is an electric push rod 441, fixedly mounted on the fixing component 431, with its movable rod's middle section fixedly connected to the end of the steel pipe. When angle adjustment is needed, the electric push rod 441 is driven to extend or retract, simultaneously moving the steel pipe. The steel pipe then drives the vibration damping component 41, thereby tilting the photovoltaic panel 1. Driving the electric push rod 441 to extend or retract moves the steel pipe, achieving angle tilt adjustment of the photovoltaic panel 1. This not only allows for more precise and flexible adjustment of the photovoltaic panel 1's angle, adapting to changes in the solar incidence angle at different times and improving photoelectric conversion efficiency, but also enhances the stability and wind resistance of the entire support system 3, reducing the risk of damage caused by strong winds. Furthermore, the hollow structure of the steel pipe reduces processing costs and facilitates widespread use.

[0030] Example 4: Unlike Example 1, the connecting component 42 is a flexible cable 442, which is fixedly mounted with several ear plates 45 corresponding to the vibration damping components 41, and the vibration damping components 41 and ear plates 45 are rotatably connected together; the adjuster 44 is a geared motor 443, which is fixedly mounted on one of the fixing parts 431, and a winding wheel 444 is also provided on the shaft of the speed motor; the two ends of the flexible cable 442 can move through the fixing part 431 respectively, and then the two ends of the flexible cable 442 are fixedly connected to the upper end and the lower end of the winding wheel 444 respectively. When the winding wheel 444 rotates forward or backward, it drives the ear plates 45 on the flexible cable 442 to move away from or towards the geared motor 443. When angle adjustment is required, the winding wheel 444 is rotated clockwise or counterclockwise by controlling the rotation speed motor. At this time, the flexible cable 442 is wound clockwise or counterclockwise onto the winding wheel 444. During this process, the ear plate 45 on the flexible cable 442 moves away from or closer to the geared motor 443. The ear plate 45 cooperates with the vibration damping component 41 to pull the vibration damping component 41 to offset, thereby driving the photovoltaic panel 1 to move and realize the adjustment of the photovoltaic panel angle. The flexible cable 442 can better adapt to the installation requirements under different terrain conditions, while also reducing material costs and maintenance difficulty. In addition, the method of using the geared motor 443 to drive the winding wheel 444 realizes the automation and remote control of the angle of the photovoltaic panel 1, which greatly improves the convenience and efficiency of operation.

[0031] Example 5: The difference from Example 1 is that the vibration damping component 41 includes a threaded steel bar 411 and a vibration damping rubber 412; a cable clamp 413 is installed at the top of the threaded steel bar 411 and a connecting fork 414 is installed at the bottom; the vibration damping rubber is installed in the middle of the cable clamp 413, and the steel strand 2 passes through the vibration damping rubber and is fixed by the cable clamp 413; a pin is provided on the connecting fork 414, and the connecting fork 414 is rotatably connected to the ear plate 45 through the pin. The vibration damping rubber 412 is used to absorb and disperse vibration energy when vibration occurs. When an external force is applied to the flexible photovoltaic support 3, the steel strand 2 is transmitted to the cable clamp 413 through the vibration damping rubber 412. The vibration damping rubber 412 has good elastic properties and can effectively absorb and buffer vibration energy, reduce the impact on the support 3 system, and enhance the stability and safety of the system. The connecting fork 414 is connected to the ear plate 45 through the pin, allowing a certain degree of rotational freedom. This helps to maintain the stability of the support 3 under the action of forces in different directions. When it is necessary to adjust the angle of the photovoltaic panel 1, the connecting component 42 can be controlled to drive the vibration damping component 41 to move by controlling the adjuster 44 of the angle adjustment component 43. Then, the vibration damping component 41 is pulled by the connecting fork 414 to offset, which facilitates the adjustment of the angle of the photovoltaic panel 1.
