[0056] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0057] Early solar photovoltaic systems mostly used fixed-angle flexible brackets, that is, the photovoltaic modules were installed at a fixed tilt angle. This angle was usually optimized according to the local latitude and seasonal changes to capture as much sunlight as possible with the highest average daily insolation throughout the year.

[0058] However, with the development of solar energy technology and the pursuit of higher energy output efficiency, people have realized that photovoltaic support systems that can track the movement of the sun in real time can significantly improve power generation efficiency. The incident angle of sunlight changes continuously throughout the day, so if photovoltaic panels can always remain perpendicular (or nearly perpendicular) to the sunlight, they can maximize absorption and conversion into electrical energy.

[0059] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0060] According to an embodiment of the utility model, on the one hand, a flexible photovoltaic bracket 100 is provided, comprising a column 1, an arc-shaped support frame 2, a driving mechanism and a support cable 4. Among them, a plurality of columns 1 are arranged at intervals. The arc-shaped support frame 2 is arranged on the top of the column 1 and is rotatably connected to the column 1. The driving mechanism is arranged on the column 1, and the power output end is connected to the arc-shaped support frame 2, which can drive the arc-shaped support frame 2 to rotate along the arc of the arc-shaped support frame 2, and an angle is formed between the rotation axis of the arc-shaped support frame and the vertical direction. The two ends of the support cable 4 are respectively connected to an arc-shaped support frame 2, and the support cable 4 is used to support the photovoltaic module.

[0061] The flexible photovoltaic bracket 100 of the utility model tensions at least two support cables 4 through the arc-shaped support frame 2, and supports the photovoltaic module through the support cables 4. When the inclination angle of the photovoltaic module needs to be adjusted, the arc-shaped support frame 2 can rotate along its own arc so that the photovoltaic module can face the maximum incident angle of the sunlight. Since the arc-shaped support frame 2 rotates along its own arc, the distance of the support cables 4 remains unchanged during the rotation, the support cables 4 will not expand or contract during the rotation, and the prestress loss of the support cables 4 will not be caused, and the damage to the photovoltaic module caused by the expansion and contraction of the support cables 4 is avoided.

[0062] Preferably, in this embodiment, two adjacent support cables 4 are parallel to each other. Since the flexible photovoltaic support 100 needs to move frequently, in order to ensure that it has sufficient rigidity and stability and avoid deformation or damage due to external factors such as wind load and snow load, the column 1 of the flexible photovoltaic support 100 is preferably made of steel structure to improve its structural strength. The support cable 4 is preferably, but not limited to, a steel wire rope.

[0063] In one embodiment, the flexible photovoltaic support 100 further includes a collection device and a control device. The collection device can obtain the current sun position. Figure 4 and Figure 5 As shown, the control device is in communication connection with the collection device and the driving mechanism, and can control the driving mechanism to drive the arc-shaped support frame to rotate according to the current sun position to adjust the inclination angle of the photovoltaic assembly relative to the ground.

[0064] Among them, the collection device can be selected as a sunlight sensor, which can detect the intensity of sunlight and convert it into an electrical signal. The control device can monitor the changes in the position of the sun in real time according to the detection results of the sunlight sensor, thereby driving the bracket motor to rotate so that the photovoltaic component is always facing the optimal incident angle of sunlight, thereby maximizing the absorption of sunlight and converting it into electrical energy.

[0065] As a convertible implementation method, the collection device is a time module, which can be used to obtain the current time. The control device stores sunshine information such as the rising and setting time of the sun, as well as the altitude angle and azimuth angle. The control device can control the driving mechanism to control the arc support frame 2 to rotate along its own arc, so that the photovoltaic module can always face the optimal incident angle of the sunlight.

[0066] The control device may include a programmable logic control component (such as a PLC or a CPU), a memory, and electronic components connected to the programmable logic control component, which are well known to those skilled in the art and will not be described in detail here. The communication connection is preferably, but not limited to, a wire connection or a signal connection.

[0067] In one embodiment, the flexible photovoltaic support 100 further includes:

[0068] The weather acquisition module can obtain the current weather. The control device is communicated with the weather acquisition module. When the weather acquisition module obtains the preset weather, the control device can control the driving mechanism to drive the arc-shaped support frame to rotate according to the preset weather to adjust the inclination angle of the photovoltaic component relative to the ground.

[0069] For example, in heavy snow weather, the control device can control the driving mechanism to tilt the photovoltaic module to reduce the amount of snow falling on the photovoltaic module and promote the sliding of the snow falling on the photovoltaic module.

[0070] In windy weather, the control device can control the driving mechanism to drive the photovoltaic module to tilt so that the inclination angle of the photovoltaic module is parallel to the wind direction, so as to reduce the windward surface of the photovoltaic module and reduce the wind load on the photovoltaic module. Therefore, the flexible photovoltaic bracket of the utility model can avoid deformation or damage caused by external factors such as wind load and snow load.

[0071] The weather acquisition module may be a receiving device that can be used to receive local weather information, which is well known to those skilled in the art and will not be described in detail here. The weather acquisition module may also be a wind direction sensor that detects and senses external wind direction information by the rotation of a wind direction arrow, transmits it to a coaxial code disk, and outputs corresponding wind direction related values.

[0072] Usually the main body of the wind direction sensor adopts the mechanical structure of a wind vane. When the wind blows towards the tail wing of the wind vane, the arrow of the wind vane will point to the direction the wind is blowing. In order to maintain the sensitivity to the direction, different internal mechanisms are also used to distinguish the direction of the wind speed sensor.

[0073] In one embodiment, Figure 2 As shown, a through hole 101 is formed on the top of the column 1 and penetrates the column 1 along the width direction of the column 1. The arc support frame 2 includes an arc segment 201 and a support segment 202. The arc segment 201 passes through the through hole 101. The support segment 202 is connected to both ends of the arc segment 201 and is arranged on the top of the column 1, and the support cable is connected to the support segment 202.

[0074] As a convertible embodiment, the arc-shaped support frame 2 may also be optionally configured to include a circular or semicircular body, the center of which is connected to the column 1 via a rotating shaft, and the support cable 4 is connected to the body.

[0075] As another convertible embodiment, a linear drive mechanism is provided in the column 1, and the column 1 can be extended and retracted in the vertical direction under the action of the linear drive mechanism. Through such a setting, the inclination angle of the photovoltaic panel 7 is more comprehensive, which helps the photovoltaic panel 7 to maximize the absorption of sunlight and convert it into electrical energy. Among them, the linear drive mechanism can be selected as a device that can output linear motion, such as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder or a combination of a motor and a gear rack.

[0076] In one embodiment, Figure 6 As shown, the arc-shaped support frame also includes a U-shaped plate 203 and a U-shaped bolt 204. The U-shaped plate 203 includes a first side plate, a second side plate and a connecting plate. The first side plate and the second side plate are respectively connected to the two sides of the support section 202. The connecting plate is located above the support section 202 and connected between the first side plate and the second side plate. The connecting plate is formed with a first connecting hole and a second connecting hole. The two ends of the U-shaped bolt 204 pass through the first connecting hole and the second connecting hole respectively, and are threadedly connected to the connecting plate. A through hole is formed between the U-shaped plate 203 and the U-shaped bolt 204, and the support cable 4 passes through the through hole. An anti-slip structure is formed at the end of the support cable 4, and the cross-sectional area of ​​the anti-slip structure is larger than the through hole.

[0077] In one embodiment, a guide groove is formed on one of the hole wall of the via hole 101 and the arc segment 201, and a guide protrusion that can slide along the guide groove is formed on the other of the hole wall of the via hole 101 and the arc segment 201. The guide protrusion can cooperate with the guide groove, so that the rotation of the arc support frame 2 is smoother.

[0078] In one embodiment, the support section 202 is hinged to the top of the column 1, which can ensure that the arc-shaped support frame 2 rotates along its own arc. The support section 102 and the arc section 201 can respectively cooperate with different positions of the column 1, ensuring that the arc-shaped support frame 2 can rotate along its own circle and is not easily tilted due to wind load.

[0079] In one embodiment, the driving mechanism includes a rotation source and a rotating wheel. The rotation source is arranged on the column 1. The rotating wheel is connected to the power output end of the rotation source, the rotating shaft of the rotating wheel extends in the vertical direction, a plurality of first teeth arranged at intervals are formed on the outer circumference of the rotating wheel, a plurality of second teeth arranged at intervals are formed on the outer circumference of the arc-shaped support frame 2, and the first teeth mesh with the second teeth.

[0080] The rotation source can indirectly drive the arc-shaped support frame 2 to rotate along its own axis through the rotating wheel.

[0081] As a convertible implementation, the arc-shaped support frame can also be selected to rotate along its own arc through a gear rack structure or a connecting rod mechanism.

[0082] In one embodiment, the two columns 1 at both ends of the flexible photovoltaic support 100 are defined as the first column and the second column, respectively, and the rotating wheel includes a first rotating wheel 501, a second rotating wheel 502 and a transmission belt 503. Among them, the first rotating wheel 501 is arranged on the side of the first column close to the second column, and is engaged with the arc support frame 2 on the first column, and the second rotating wheel 502 is arranged on the side of the second column away from the first column, and is engaged with the arc support frame 2 on the second column, and the power output end of the rotating source is connected to the first rotating wheel 501 and / or the second rotating wheel 502. The transmission belt 503 is sleeved outside the first rotating wheel 501 and the second rotating wheel 502.

[0083] Through such an arrangement, the first rotating wheel 501 and the second rotating wheel 502 can rotate synchronously under the drive of the transmission belt 503, thereby driving the arc-shaped support frame 2 at both ends to rotate synchronously, so as to ensure that the rotation angles of the arc-shaped support frame 2 at both ends of the flexible photovoltaic bracket 100 are consistent, so as to ensure that the inclination angles of the photovoltaic components on the support cable are consistent.

[0084] In one embodiment, the flexible photovoltaic support 100 further includes a diagonal brace 6, which can be supported between the column 1 and the ground. Preferably, the diagonal brace 6 on the first column is supported on the side of the first column close to the second column, and the diagonal brace 6 on the second column is supported on the side of the second column close to the first column, which can resist the tension stress generated by the tensioning of the support cable 4.

[0086] First, the bottom of the column 1 is fixed on the pile foundation, and the arc-shaped support frame 2 is installed on the column 1 , and the arc-shaped support frame 2 is hinged to the support cable 4 .

[0087] Next, a diagonal brace 6 is set between the column 1 and the ground. After the construction of the column 1 is completed, the support cable 4 is tensioned for the first time. After the initial tensioning is completed, the photovoltaic module is installed on the support cable 4. After the photovoltaic module is installed, the support cable 4 is tensioned for the second time.

[0088] It should be noted that during installation, the design plan should be strictly followed, the initial position and operating parameters of the tracking system should be calibrated to ensure smooth linkage of all parts. Regularly check the operating status and wear of the tracking system, and perform maintenance in a timely manner to ensure that the tracking effect is not reduced.
