[0002] With the development of the economy and the increase in population, land resources are becoming increasingly scarce. Traditional photovoltaic power stations require a large area of land and are no longer suitable for the current land situation. In addition, due to the diverse topographies and landforms in remote areas, there are often irregular terrains such as slopes and hills. Traditional photovoltaic brackets adopt a fixed installation structure, and their shapes cannot be changed after installation, resulting in the inability to adapt to various complex terrains and environmental conditions. Moreover, traditional photovoltaic brackets are vulnerable to bad weather and have certain safety hazards.

[0003] In addition, with the development of the construction industry, more and more buildings are beginning to adopt photovoltaic technology. However, traditional photovoltaic brackets cannot be integrated with buildings, and thus cannot meet the design goal of building-photovoltaic integration required by the development of the construction industry.

Detailed implementation manner

[0031] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0032] As Figure 1 、 Figure 2 shown, a foldable flexible photovoltaic power generation device includes a flexible photovoltaic bracket and multiple groups of photovoltaic modules 3. The flexible photovoltaic bracket includes a support structure, a load-bearing cable 1 and a foldable photovoltaic bracket 2. The foldable photovoltaic bracket 2 is arranged on the load-bearing cable 1, and the foldable photovoltaic bracket 2 can be unfolded or folded along the two-side load-bearing cables 1 through a retracting and deploying mechanism; multiple groups of photovoltaic modules 3 are arranged in rows on the foldable photovoltaic bracket 2 and can be folded or unfolded along with the foldable photovoltaic bracket 2; the support structure is arranged at both ends of the load-bearing cable 1, and both ends of the load-bearing cable 1 are connected to the support structure through a rotating mechanism for adjusting the inclination angle of the photovoltaic module 3; both the retracting and deploying mechanism and the rotating mechanism are connected to a controller (not shown in the figure). Among them, the photovoltaic modules are arranged in a matrix on the foldable photovoltaic bracket to form a photovoltaic panel group, and can be folded or unfolded along with the telescopic movement of the foldable photovoltaic bracket along the flexible load-bearing cable, which is flexible and convenient to apply. At the same time, the controller can control the telescopic movement of the foldable photovoltaic bracket and the inclination angle of the photovoltaic module according to the weather conditions, which can increase the power generation. During the operation process, basically no manual operation is required, and the automatic unfolding and contraction of the folded photovoltaic module can be realized according to the real-time monitored surrounding environmental conditions, which improves the degree of automation.

[0033] In a specific embodiment of the present invention, as Figure 4As shown in the figure, the rotation mechanism includes a reduction motor 4, a rotating shaft 5 and a rotating rod 6. The output shaft 40 of the reduction motor 4 passes through the column 7 of the support structure and is fixedly connected coaxially with the rotating shaft 5. The end of the rotating shaft 5 is fixedly connected to the middle of the rotating rod 6. The rotating shaft 5 is arranged perpendicular to the rotating rod 6. Both ends of the rotating rod 6 are fixedly connected to the ends of the load-bearing cables 1 on both sides. The reduction motor 4 is connected to the controller. A through hole perpendicular to the central axis is provided at the end of the rotating shaft for the rotating rod to pass through, and self-tapping screws with anti-corrosion characteristics are used for fixation. In addition, a photosensitive sensor (not shown in the figure) is also included. The photosensitive sensor and the reduction motor 4 are both connected to the controller. The controller controls the rotation mechanism through the solar radiation sensed by the photosensitive sensor to adjust the inclination angle of the photovoltaic module 3. When the photovoltaic module is unfolded, the photosensitive sensor determines the inclination angle of the photovoltaic panel by sensing the solar radiation at different times of the day. The photosensitive sensor can sense the change in solar radiation, that is, the change in light energy. The photosensitive sensor transmits the signal to the controller, and the controller issues an action instruction to the reduction motor, which can realize the control of the inclination angle of the photovoltaic module, so that the photovoltaic module receives as much solar radiation as possible and improves the power generation efficiency.

[0034] In another specific embodiment of the present invention, the reduction motor that provides power for the rotation of the photovoltaic module can also be placed at the support head at the top of the column of the support stay cable. By connecting the stay cable with the reduction motor, the reduction motor can drive the photovoltaic module to rotate. The specific implementation effect is the same as that when the reduction motor is placed in the middle position of the rotating rod.

[0035] As a preferred structure, as Figures 1-3 shown, the support structure includes a column 7 and a stay cable 8. Both ends of the rotating rod 6 are connected to the top of the column 7 through the stay cable 8. A support head 9 for supporting the stay cable 8 is provided at the top of the column 7. During the application process, the column resists the force in the vertical direction, and the stay cable resists the force in the horizontal direction. During manufacturing, the column 7 is made of a steel column, and a foundation (not shown in the figure) below the ground is provided at the bottom of the column. The stay cable can provide tension for both ends of the short side of the photovoltaic module on the foldable photovoltaic bracket, so that the photovoltaic panel group structure is stable. The foldable photovoltaic bracket is supported by a flexible steel cable as the load-bearing cable. At the same time, in order to reduce the bending moment of the support heads at the top of the two end columns, external tension stay cables are used to support both ends of the rotating rod. Or the support structure adopts a triangular plate-like structure with internal rigid diagonal braces.

[0036] In a specific embodiment of the present invention, as Figure 5 、 6As shown in the figure, the support head 9 includes a support base 91, a spring plunger 92 and a spring 93. One end of the support base 91 is vertically fixed to the inner side of the column 7. The inside of the support base 91 is provided with a counterbore and two sector grooves 94 that provide a rotation space for the stay cables 8. The two sector grooves 94 are symmetrically arranged on both sides of the counterbore, and the tops of the two sector grooves 94 communicate above the counterbore. The spring 93 and the spring plunger 92 are arranged in the counterbore. The spring 93 is arranged at the bottom of the counterbore, and the spring plunger 92 is arranged on the top of the spring 93. The lower end of the spring plunger 92 abuts against the spring 93, and the upper ends of the two stay cables 8 are connected to the top of the spring plunger 92. Among them, the two stay cables 8 share a steel cable. The steel cable sequentially passes through the two sector grooves 94, and the two ends of the steel cable are fixed to the two ends of the rotating rod 6 and are arranged inside the load-bearing cable 1. During the rotation of the photovoltaic module, the stay cables will inevitably sag or shake due to their own gravity or the influence of wind. The spring can keep the stay cables taut when they sag and shake, and always provide tension on both sides of the short sides of the photovoltaic panel group to maintain the stability of the overall structure.

[0037] During the specific design, an installation block 10 connected to the support head 9 is provided at the top of the column 7. The support head 9 can be fixed to the inner side of the installation block 10. This split structure is convenient for processing and manufacturing. The photovoltaic module 3 is fixed to the foldable photovoltaic bracket 2 through fixing clamps 30 around it; the diameter of the load-bearing cable 1 is 10 mm, and prestressed galvanized steel strands or high-vanadium cables are used. If anti-corrosion is treated by hot-dip galvanizing, the thickness of the galvanized layer is not less than 65 μm.

[0038] In a specific embodiment of the present invention, such as Figure 7 , 8As shown in the figure, the foldable photovoltaic support 2 includes a number of fan-shaped support frames 20. The support frame 20 is a frame capable of placing the photovoltaic module 3. A support rod 21 is provided at the starting end of the support frame 20. Both ends of the support rod 21 are fixedly connected to the ends of the load-bearing cable 1. Both side frames 22 of the support frame 20 can be rotatably connected to both ends of the support rod 21. A number of fan-shaped support frames 20 can be folded and suspended on the load-bearing cable 1 in pairs; the end of the support frame 20 is connected to the retracting and deploying mechanism. Among them, two load-bearing cables 1 arranged side by side up and down are respectively provided on both sides of the foldable photovoltaic support 2. The ends of adjacent groups of support frames 20 are hinged to two sliders 11. The two sliders 11 are symmetrically arranged at both ends of the connecting rod 12. The slider 11 is arranged between the two load-bearing cables 1 on the same side and can slide along the length direction of the load-bearing cable 1. Among them, through holes matching the load-bearing cable are provided at both the upper and lower ends of the slider 11; one end of the frame 22 is bent upward and the other end is bent downward, which is convenient for folding the support frame. During production, in order to improve the strength and stiffness of the photovoltaic support and ensure the safety of the photovoltaic module, a high-strength aluminum alloy is used for the folding structure design, which has good durability and stability and can ensure the safety and reliability of long-term use; the connection points of the support frames are fixed with self-tapping screws with anti-corrosion characteristics, which can bear a certain load and ensure sufficient strength.

[0039] In addition, a plurality of photovoltaic modules are arranged in parallel between the two side frames and are arranged in a row along the length direction of the load-bearing cable. The photovoltaic modules form a matrix arrangement structure between the load-bearing cables. In specific applications, multiple rows of load-bearing cables and multiple rows of photovoltaic modules can be arranged, and the number of photovoltaic modules can be adjusted according to the actual situation.

[0040] As a preferred structure, the retracting and deploying mechanism includes a winch (not shown in the figure) and a towing rope (not shown in the figure). One end of the towing rope can be wound around the drum of the winch, and the other end of the towing rope can be connected to the end support frame. The winch pulls the end of the support frame through the towing rope to realize the folding or unfolding of the photovoltaic module. The number and installation position of the winches can be determined according to the actual situation and can be installed on the column or a fixed object outside the column, as long as it is convenient to realize the folding and unfolding of the support frame.

[0041] Further optimizing the above technical solution, it further includes a wind detector (not shown in the figure). The wind detector and the winch are both connected to the controller. According to the weather conditions sensed by the wind detector in real time, the controller controls the action of the winch according to the weather conditions to realize the contraction of the support frame. In case of extreme weather, all can be folded to protect the photovoltaic panels from damage.

[0042] During specific assembly, apply butter to the wiring of the photosensitive sensor, wind detector, and controller, as well as the surface of the equipment housing for thorough sealing. At the same time, install high-performance shock-absorbing devices (select rubber pads and / or shock-absorbing springs) around it, and ground its housing separately to ensure a stable zero potential.

[0043] The specific application process of the present invention is as follows: The initial state of the photovoltaic module should be Figure 2 the folded state when not working as shown. When working normally, the winch drives the end support frames to unfold the support frames on the load-bearing cables one by one, thereby driving the overall horizontal unfolding of the photovoltaic module (as Figure 1 shown), and providing a certain pre-tightening force after all are unfolded. The implementation method of the tracking function: After the photovoltaic module is fully unfolded, the photosensitive sensor provides information and is converted into an instruction by the controller to drive the reduction motor to drive the rotating shaft assembled with the rotating rod to rotate, realizing the change of the inclination angle of the photovoltaic module.

[0044] When extreme weather occurs, such as strong wind weather, when the wind force signal sensed by the wind detector is transmitted to the controller, and it is calculated through the internal program that the force on the photovoltaic module exceeds the structural force limit and does not meet the strength requirements, the controller provides an instruction to control the reduction motor to change the inclination angle between the photovoltaics to make it horizontal, and drive the winch to fully fold the photovoltaic module to protect the overall structure, and its state should be as Figure 2 shown.

[0045] The present invention has a wide range of application scenarios and is convenient for popularization and application. Specifically, there are the following aspects:

[0046] I. Installation on urban rooftops:

[0047] 1. The fully foldable design makes this flexible photovoltaic bracket extremely flexible when installed on urban rooftops. The space on urban rooftops is limited, and there are often various obstacles and irregular shapes. The foldable photovoltaic bracket can be flexibly adjusted according to the actual situation of the rooftop to adapt to various complex installation environments. This design not only simplifies the installation process but also improves the utilization rate of rooftop space.

[0048] 2. The present invention adopts a single-axis horizontal design, enabling the flexible photovoltaic bracket to automatically adjust the angle to maximize the utilization of solar energy resources.

[0053] 2. The single-axis tracking design enables the photovoltaic bracket to automatically adjust the angle to capture solar energy to the maximum extent. In remote areas, there is often a lack of stable power supply, and solar energy, as a clean and renewable energy source, has great development potential. The photovoltaic bracket with a single-axis tracking design can be automatically adjusted according to the sun's movement trajectory to ensure that the photovoltaic panels always face the sun, improve the power generation efficiency, and thus meet the power demand in remote areas.

[0054] 3. The intelligent flexible folding design enables the photovoltaic bracket to adapt to various complex terrains and environmental conditions.

[0058] 2. The horizontal single-axis design ensures that the photovoltaic bracket can maintain the best power generation efficiency under different environmental conditions. Whether it is sunny or cloudy, the bracket can automatically adjust the angle so that the photovoltaic panels always face the sun, thus ensuring a stable power output. This is particularly important for the disaster area because the stability of power supply directly affects the progress of rescue work.

[0059] 3. The application of intelligent technology enables this kind of photovoltaic bracket to have the ability of remote monitoring and management. Rescue personnel can understand the working status, power generation amount and other information of the bracket in real time through the intelligent system and adjust the power generation strategy as needed. This intelligent management not only improves the reliability of power supply but also reduces the operation and maintenance costs.

[0060] 4. The flexible foldable design enables the photovoltaic bracket to adapt to various complex terrains and environmental conditions. In the disaster area, the terrain may be rough, but this bracket can be flexibly adjusted to ensure the stable installation of the photovoltaic panels and the power generation efficiency is not affected.

[0061] 5. Considering from the perspective of disaster relief costs, the use of this kind of photovoltaic bracket helps to reduce the dependence on external power supply, shorten the time and cost of power restoration in the disaster area. At the same time, due to its high-efficiency and stable power generation performance, it can also provide sufficient power support for rescue equipment and improve the rescue efficiency.

[0062] IV. Integration of agriculture and photovoltaics:

In the seasons when sufficient sunlight needs to be provided for crops, the bracket can be partially or fully folded up to ensure that the crops receive sufficient sunlight. In other seasons, the bracket can be unfolded to provide power support for agricultural facilities and achieve energy self-sufficiency.

[0064] 2. The horizontal single-axis design enables the photovoltaic bracket to automatically adjust the angle along with the movement trajectory of the sun, ensuring that the photovoltaic panels always face the sun and maximizing the utilization of solar energy resources. This not only improves the power generation efficiency but also provides a stable and reliable power supply for agricultural facilities, helping to promote the modernization and intelligentization of agricultural production.

[0065] 3. The application of intelligent technologies enables this kind of photovoltaic support to have the ability of remote monitoring and management. Through the intelligent system, agricultural managers can understand the working status, power generation and other information of the photovoltaic support in real time, and make flexible adjustments according to the actual needs of agricultural production. This helps to achieve the coordinated development of agriculture and the new energy industry and improve the overall economic benefits.

[0070] 2. Intelligent technologies enable this kind of photovoltaic support to have the ability of remote monitoring and management. Through the intelligent system, the working status, power generation and other information of the support can be understood in real time, and fault warning and remote maintenance can be carried out. This is particularly important for mobile energy stations because personnel may not be able to monitor and maintain on site in real time, and intelligent technologies can ensure the stable operation of the photovoltaic support and reduce the possibility of faults.

[0071] 3. The flexible folding design makes this kind of photovoltaic support have better adaptability and durability.
