[0032] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] Example 1

[0034] In the related art, when using solar energy to generate electricity, offshore photovoltaic equipment is unable to adjust the photovoltaic panels according to the angle of light, which affects the efficiency of photovoltaic power generation.

[0035] To solve the above technical problems, refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a single-axis support structure 100 for an offshore photovoltaic system. The single-axis support structure 100 includes a floating body 110 , a column assembly 120 and a beam assembly 130 .

[0036] Specifically, combined Figures 2 to 4As shown, the column assembly 120 includes a fixed rod 121 and a movable rod 122, one end of the fixed rod 121 is connected to the floating body 110, and the end of the fixed rod 121 away from the floating body 110 is telescopically connected to the movable rod 122; the beam assembly 130 includes a beam 131, a movable member 132 and a driving member 133, the beam 131 is connected to the photovoltaic panel 140, the driving member 133 is connected to the movable member 132, the beam 131 is movably connected to the end of the movable rod 122 away from the fixed rod 121 through the movable member 132, and the movable member 132 It is arranged between the movable rod 122 and the photovoltaic panel 140. Accordingly, the single-axis support structure 100 can float on the sea through the floating body 110. The movable rod 122 is telescopic relative to the fixed rod 121. When the movable rod 122 is telescopic, it drives the photovoltaic panel 140 to move, so that the height of the photovoltaic panel 140 is changed to adjust the height of the single-axis support structure 100. The driving member 133 can drive the movable member 132 to adjust the inclination angle of the photovoltaic panel 140, so that the photovoltaic panel 140 is adjusted to different positions and postures according to the lighting time, and the height and angle of the photovoltaic panel 140 are adjusted.

[0037] It is understandable that the adjustment angle and height of the photovoltaic panel 140 are crucial to its light energy absorption efficiency. The angle of the photovoltaic panel is automatically adjusted with the movement of the sun to ensure that it is always perpendicular to the sunlight, reducing obstacles that block the photovoltaic panel 140, thereby achieving higher light energy absorption and conversion efficiency.

[0038] refer to Figure 1 and Figure 2 As shown, the uniaxial support structure 100 has a first direction. Exemplarily, the first direction is taken as the length direction of the uniaxial support structure 100. It can be understood that the above definition is only for the convenience of understanding the relative position relationship of each part in the uniaxial support structure 100, and should not be understood as a limitation of the present application. It should be noted that the floating body 110 and the beam assembly 130 are both arranged along the first direction, and the column assembly 120 is arranged perpendicular to the first direction.

[0039] In one embodiment, optionally, the movable part 132 includes a rotating part 1321 and a fixed part 1322, the fixed part 1322 is movably connected to the rotating part 1321, and the fixed part 1322 is connected to the movable rod 122 on a side away from the rotating part 1321, and the rotating part 1321 can rotate to drive the beam 131 to rotate, thereby allowing the beam 131 to drive the photovoltaic panel 140 to adjust its position and posture.

[0040] Optionally, the driving member 133 can drive the movable member 132 to rotate, and the rotation direction of the movable member 132 is perpendicular to the cross beam 131, so that the movable member 132 can drive the cross beam 131 to rotate during the rotation process, and the rotation direction of the movable member 132 is the same as the rotation direction of the cross beam 131. It should be noted that the driving member 133 is a component in the mechanical device that is responsible for transmitting power and causing other components to rotate. The driving member 133 can be a motor that drives the movable member 132 to rotate using a gear transmission, or a motor that drives the movable member 132 to rotate using a worm gear transmission, which will not be described in detail here.

[0041] In one embodiment, optionally, reference Figure 1 and Figure 2 As shown, there are multiple column assemblies 120 and multiple movable parts 132. The multiple column assemblies 120 are arranged in parallel with each other at intervals. One column assembly 120 corresponds to one movable part 132. The multiple column assemblies 120 are rotatably connected to the beam 131 through the movable parts 132 respectively. The column assemblies 120 provide better support for the beam 131, and the rotation process of the beam 131 will not affect the column assemblies 120.

[0042] In summary, the single-axis support structure 100 for the offshore photovoltaic system can float on the sea through the floating body 110, and the movable rod 122 can be extended and retracted relative to the fixed rod 121. When the movable rod 122 is extended and retracted, it drives the photovoltaic panel 140 to move, so that the height of the photovoltaic panel 140 changes to adjust the height of the single-axis support structure 100. The driving member 133 can drive the movable member 132 to adjust the inclination angle of the photovoltaic panel 140, so that the photovoltaic panel 140 is adjusted to different positions and postures according to the lighting time, thereby achieving the purpose of adjusting the height and angle of the photovoltaic panel 140 and improving the power generation efficiency of the photovoltaic panel 140.

[0043] Example 2

[0044] refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides another single-axis support structure 100 for an offshore photovoltaic system. The single-axis support structure 100 includes a floating body 110 , a column assembly 120 and a beam assembly 130 .

[0045] In this embodiment, in order to adapt to the special requirements of the marine environment, the float 110 is selected to have a frame structure composed of floating tubes or pontoons. The material of the float 110 can be high-density polyethylene (HDPE), which is light and easy to install and has a long service life. The material of the float 110 can also be reinforced plastic, such as fiber reinforced plastic (FRP), to increase the structural strength and durability, so as to have corrosion resistance, wind and wave resistance, environmental protection and recyclability, and good buoyancy characteristics.

[0046] Specifically, combined Figures 2 to 4 As shown, the column assembly 120 includes a fixed rod 121 and a movable rod 122, one end of the fixed rod 121 is connected to the float 110, and the end of the fixed rod 121 away from the float 110 is telescopically connected to the movable rod 122. Accordingly, the single-axis support structure 100 can float on the sea through the float 110, and the movable rod 122 is telescopic relative to the fixed rod 121. When the movable rod 122 is telescopically moved, it drives the photovoltaic panel 140 to move, so that the height of the photovoltaic panel 140 changes, so as to adjust the height of the single-axis support structure 100.

[0047] Specifically, the beam assembly 130 includes a beam 131, a movable part 132 and a driving part 133. The beam 131 is connected to the photovoltaic panel 140, and the driving part 133 is connected to the movable part 132. The beam 131 is movably connected to an end of the movable rod 122 away from the fixed rod 121 through the movable part 132. The movable part 132 is arranged between the movable rod 122 and the photovoltaic panel 140. The driving part 133 can drive the movable part 132 to adjust the inclination angle of the photovoltaic panel 140, so that the photovoltaic panel 140 can be adjusted to different positions and postures according to the lighting time, and the height and angle of the photovoltaic panel 140 can be adjusted.

[0048] refer to Figure 1 and Figure 2 As shown, the single-axis support structure 100 has a first direction. Exemplarily, the first direction is taken as an example of the length direction of the single-axis support structure 100.

[0049] In one embodiment, optionally, the movable member 132 includes a rotating portion 1321 and a fixed portion 1322, the fixed portion 1322 is movably connected to the rotating portion 1321, and the fixed portion 1322 is connected to the movable rod 122 at a side away from the rotating portion 1321. Exemplarily, the movable member 132 may be a universal joint or a universal joint bearing, the fixed portion 1322 is fixedly connected to the movable rod 122, and the rotating portion 1321 can rotate to drive the crossbeam 131 to rotate, thereby causing the crossbeam 131 to drive the photovoltaic panel 140 to adjust the position and posture.

[0050] It should be noted that the universal joint is a mechanical component that is mainly used to achieve power transmission between different axes, especially for application scenarios where the direction of the transmission axis needs to be changed. The core function of the universal joint is to effectively transmit rotational motion and torque when the axes intersect and the relative positions are constantly changing.

[0051] Optionally, combined Figure 4 and Figure 5 As shown, the rotating part 1321 is provided with a through slot 1323, and the cross beam 131 is passed through the through slot 1323 and is engaged with the slot wall of the through slot 1323. It can be understood that the rotating part 1321 can be a universal joint bearing with a cylindrical structure, so that the cross beam 131 passes through the through slot 1323 of the rotating part 1321. In other words, when the rotating part 1321 drives the cross beam 131 to perform relative movement, the cross beam 131 drives the photovoltaic panel 140 to rotate, so that the angular position of the photovoltaic panel 140 changes.

[0052] Furthermore, if Figure 4 As shown, the through groove 1323 is a square structure, and the cross section of the beam 131 along the first direction is a square structure. The size of the through groove 1323 of the square structure is compatible with the beam 131, so that the beam 131 and the rotating part 1321 rotate coaxially. During the rotation, the beam 131 drives the photovoltaic panel 140 to rotate, thereby adjusting the angle and position of the photovoltaic panel 140 and improving the light energy absorption and conversion efficiency.

[0053] Optionally, the driving member 133 can drive the movable member 132 to rotate, and the rotation direction of the movable member 132 is perpendicular to the cross beam 131, so that the movable member 132 can drive the cross beam 131 to rotate during the rotation process, and the rotation direction of the movable member 132 is the same as the rotation direction of the cross beam 131. Further, the driving member 133 can be an electric motor that drives the movable member 132 to rotate by means of gear transmission, or an electric motor that drives the movable member 132 to rotate by means of a worm gear transmission.

[0054] In one embodiment, optionally, reference Figure 1 and Figure 2 As shown, there are multiple column assemblies 120 and movable parts 132. The multiple column assemblies 120 are arranged in parallel with each other at intervals. Each column assembly 120 is arranged between the beam 131 and the float 110. One column assembly 120 corresponds to one movable part 132. The multiple column assemblies 120 are rotatably connected to the beam 131 through the movable parts 132 respectively. The column assembly 120 has a better supporting effect on the beam 131. The column assembly 120 can raise or lower the beam 131, and the rotation process of the beam 131 will not affect the column assembly 120.

[0055] Furthermore, the plurality of column assemblies 120 are respectively perpendicular to the beam 131 , and the beam 131 is supported by the plurality of column assemblies 120 and work together to provide better support, and the column assemblies 120 can be telescopic to raise or lower the height of the beam 131 , thereby adjusting and controlling the height of the photovoltaic panel 140 .

[0056] In one embodiment, optionally, in combination Figure 4 and Figure 5 As shown, the uniaxial support structure 100 further includes a mounting bracket 150, which is disposed between the crossbeam 131 and the photovoltaic panel 140. Accordingly, the photovoltaic panel 140 is mounted on the mounting bracket 150, which is mounted on the crossbeam 131. The mounting bracket 150 plays a fixing and supporting role on the photovoltaic panel 140. When the crossbeam 131 rotates relatively, the photovoltaic panel 140 is driven to rotate in the same direction through the mounting bracket 150. Furthermore, the material of the mounting bracket 150 can be selected from metal or non-metal, and the material of the mounting bracket 150 can also be a metal alloy.

[0057] It is understood that the rotation adjustment of the photovoltaic panel 140 is to maximize its efficiency in receiving sunlight, because the position of the sun changes with time and seasons. By automatically adjusting the angle of the panel, it can be ensured that the photovoltaic panel always faces the sun, thereby improving the photoelectric conversion efficiency.

[0058] In one embodiment, optionally, the single-axis support structure 100 also includes a lighting module, which is connected to the driving member 133. The lighting module can detect and output lighting parameters to control the driving member 133. The lighting module can be a light sensor, which can detect light intensity and form lighting parameters. After the lighting parameters reach a preset value, the driving member 133 is adjusted and controlled, so that the driving member 133 drives the rotating member to drive the beam 131 to rotate, thereby achieving the purpose of rotating and adjusting the photovoltaic panel 140 through the driving member 133, thereby improving the energy output efficiency of the photovoltaic panel 140.

The single-axis support structure 100 is applied to the offshore photovoltaic system.

[0061] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0062] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
