DETAILED DESCRIPTION

The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, a foldable flexible photovoltaic power generation device includes a flexible photovoltaic support and multiple groups of photovoltaic components 3. The flexible photovoltaic support includes a support structure, a load-bearing cable 1 and a foldable photovoltaic support 2. The foldable photovoltaic support 2 is arranged on the load-bearing cable 1, and the foldable photovoltaic support 2 is unfolded or folded along the load-bearing cables 1 on both sides through a retractable mechanism; multiple groups of photovoltaic components 3 are arranged in a row on the foldable photovoltaic support 2 and can be folded or unfolded with the foldable photovoltaic support 2; the support structure is arranged at both ends of the load-bearing cable 1, and the two ends of the load-bearing cable 1 are connected to the support structure through a rotating mechanism for adjusting the inclination of the photovoltaic component 3; the retractable mechanism and the rotating mechanism are both connected to a controller (not shown in the figure). Among them, the photovoltaic components are arranged in a matrix on the foldable photovoltaic support to form a photovoltaic panel group, which can be folded or unfolded along the flexible load-bearing cable with the extension and contraction of the foldable photovoltaic support, and the application is flexible and convenient. At the same time, the controller can control the extension and contraction of the foldable photovoltaic support and the inclination of the photovoltaic component according to the weather conditions, which can increase the power generation. There is basically no need for human control during operation. The foldable photovoltaic panels can be automatically unfolded and retracted according to the real-time monitoring of the surrounding environment, thus improving the degree of automation.

In a specific embodiment of the present invention, as shown in FIG4 , the rotating 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 supporting structure and is coaxially fixed 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. The two ends of the rotating rod 6 are respectively 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 of the rotating shaft is provided at the end of the rotating shaft so that the rotating rod can pass through it, and is fixed with a self-tapping screw with anti-corrosion properties. 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 rotating 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 amount of solar radiation at different times of the day. The photosensor can sense the changes in solar radiation, that is, light energy. The photosensor transmits the signal to the controller, and the controller sends an action instruction to the reduction motor, which can control the inclination angle of the photovoltaic module, so that the photovoltaic module can receive as much solar radiation as possible and improve the power generation efficiency.

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

As a preferred structure, as shown in Figures 1-3, the support structure includes a column 7 and a cable 8, and the two ends of the rotating rod 6 are connected to the top of the column 7 through the cable 8. The top of the column 7 is provided with a support head 9 for supporting the cable 8. During application, the column resists the force in the vertical direction, and the cable resists the force in the horizontal direction. During manufacturing, the column 7 is made of steel, and a foundation below the ground is provided at the bottom of the column (not shown in the figure). The cable can provide tension for the short sides of the photovoltaic components on the foldable photovoltaic support, thereby stabilizing the structure of the photovoltaic panel group. The foldable photovoltaic support is supported by a flexible steel cable as a load-bearing cable. At the same time, in order to reduce the bending moment of the support heads at the top of the columns at both ends, the two ends of the rotating rod are supported by external tensioning cable. Or the support structure adopts a triangular plate structure with internal rigid oblique support.

In a specific embodiment of the present invention, as shown in Figs. 5 and 6, the support head 9 includes a support seat 91, a spring plunger 92 and a spring 93. One end of the support seat 91 is vertically fixed to the inner side of the column 7. The support seat 91 is provided with a countersink and two fan-shaped grooves 94 for providing a rotation space for the inclined cable 8. The two fan-shaped grooves 94 are symmetrically arranged on both sides of the countersink, and the tops of the two fan-shaped grooves 94 are through the top of the countersink. The spring 93 and the spring plunger 92 are arranged in the countersink, the spring 93 is arranged at the bottom of the countersink, and the spring plunger 92 is arranged at 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 inclined cables 8 on both sides are connected to the tops of the spring plunger 92. The inclined cables 8 on both sides share a common steel cable, and the steel cable passes through the two fan-shaped grooves 94 in sequence. The two ends of the steel cable are fixed to the two ends of the rotating rod 6 and are arranged on the inner side of the load-bearing cable 1. During the rotation of photovoltaic modules, the inclined cables will inevitably sag or shake due to their own gravity or wind force. The spring can be used to keep the inclined cables taut when they sag and shake, providing tension on both sides of the short sides of the photovoltaic panel group at all times to maintain the stability of the overall structure.

In the specific design, the top of the column 7 is provided with a mounting block 10 connected to the support head 9, and the support head 9 can be fixed on the inner side of the mounting block 10. This split structure is convenient for processing and manufacturing. The photovoltaic module 3 is fixed to the foldable photovoltaic support 2 by a fixing clamp 30 on all sides; the load-bearing cable 1 has a diameter of 10mm and adopts prestressed galvanized steel strands or high-vanadium cables. If hot-dip galvanizing treatment measures are adopted for anti-corrosion, the thickness of the galvanized layer is not less than 65um.

In a specific embodiment of the present invention, as shown in Figures 7 and 8, the foldable photovoltaic support 2 includes a plurality of fan support frames 20, the support frame 20 is a frame capable of placing a photovoltaic assembly 3, a support rod 21 is provided at the starting end of the support frame 20, the two ends of the support rod 21 are fixedly connected to the end of the load-bearing cable 1, the two side frames 22 of the support frame 20 can be rotatably connected to the two ends of the support rod 21, and a plurality of fan support frames 20 can be folded and hung on the load-bearing cable 1 in groups of two; the end of the support frame 20 is connected to the retractable mechanism. Among them, two sides of the foldable photovoltaic support 2 are respectively provided with two load-bearing cables 1 arranged in parallel up and down, the ends of two adjacent groups of support frames 20 are hinged on two sliders 11, the two sliders 11 are symmetrically arranged at the two ends of the connecting rod 12, and 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, the upper and lower ends of the slider 1 are provided with through holes that cooperate with the load-bearing cable; one end of the frame 22 is bent upward and the other end is bent downward, so as to facilitate the folding of the support frame. During production, in order to improve the strength and rigidity of the photovoltaic bracket and ensure the safety of photovoltaic modules, high-strength aluminum alloy is used for the folding structure design, which has good durability and stability, and can ensure safety and reliability for long-term use; the connection of the support frame is fixed with self-tapping screws with anti-corrosion properties, which can withstand a certain load and ensure sufficient strength.

In addition, multiple photovoltaic modules are arranged side by side between the two side frames, and a row is arranged along the length direction of the load-bearing cables, and 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 actual conditions.

As a preferred structure, the retractable mechanism includes a winch (not shown in the figure) and a traction rope (not shown in the figure), one end of the traction rope can be wound around the drum of the winch, and the other end of the traction rope can be connected to the end support frame. The winch pulls the end of the support frame through the traction rope to achieve the folding or unfolding of the photovoltaic module. The number and installation position of the winch can be determined according to actual conditions, and can be installed on the column or the fixed object outside the column to facilitate the folding and unfolding of the support frame.

The above technical solution is further optimized, and further includes a wind detector (not shown in the figure), and the wind detector and the winch are connected to the controller. The wind detector senses the weather conditions in real time, and the controller controls the action of the winch according to the weather conditions to achieve the contraction of the support frame. In extreme weather, the support frame can be fully folded to protect the photovoltaic panel from damage.

During the specific assembly, use butter to apply to the wiring of the photosensitive sensor, wind detector and controller as well as the surface of the equipment shell to seal it thoroughly. At the same time, install high-performance shock-absorbing devices (rubber pads and/or shock-absorbing springs) around it, and ground its shell separately to ensure that it has a stable zero potential.

The specific application process of the present invention is as follows: the initial state of the photovoltaic module should be the folded state when not in operation as shown in Figure 2. During normal operation, the end support frame is driven by the winch to unfold the support frames on the load-bearing cable one by one, thereby driving the overall horizontal unfolding of the photovoltaic module (as shown in Figure 1), and providing a certain preload force after it is fully unfolded. The tracking function is implemented in the following way: After the photovoltaic module is fully unfolded, the information provided by the photosensitive sensor is converted into instructions through the controller, driving the reduction motor to drive the rotating shaft assembled as one with the rotating rod to rotate, thereby realizing the change of the inclination angle of the photovoltaic module.

When extreme weather occurs, such as strong winds, when the wind signal sensed by the wind detector is transmitted to the controller, and the internal program calculates that the stress on the photovoltaic module exceeds the structural stress limit and does not meet the strength requirements, the controller provides instructions to control the reduction motor to change the inclination angle between the photovoltaic modules to make it horizontal, and drives the winch to fully fold the photovoltaic modules to protect the overall structure. Its state should be as shown in Figure 2.
