[0033] 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.

[0034] Example 1

[0035] refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a support structure 100 for an offshore photovoltaic system. The support structure 100 includes a floating body 110 , a support assembly 120 and an adjustment assembly 130 .

[0036] Specifically, combined Figure 3 and Figure 4As shown, the support assembly 120 includes a crossbeam 122, a column 121 and a first movable member 123, one end of the column 121 is arranged on the floating body 110, and the end of the column 121 away from the floating body 110 is movably connected to the crossbeam 122 through the first movable member 123, and the side of the connecting member away from the column 121 is connected to the photovoltaic panel 140; the adjustment assembly 130 includes a driving member 131, an adjusting member 134, a fixing rod 132 and a telescopic rod 133, the adjusting member 134 is connected to the crossbeam 122, the fixing rod 132 is telescopically connected to the telescopic rod 133, the end of the fixing rod 132 away from the telescopic rod 133 is hinged to the column 121, and the telescopic rod 133 is away from the column 121. One end of the fixed rod 132 is hinged to one end of the adjusting member 134 away from the beam 122. Accordingly, the support structure 100 can float on the sea through the floating body 110. The driving member 131 can drive the telescopic rod 133 to extend and retract relative to the fixed rod 132. When the telescopic rod 133 moves, the adjusting member 134 drives the beam 122 to rotate. The beam 122 drives the photovoltaic panel 140 to change its position. The beam 122 is movable and adjusted relative to the column 121 through the first movable member 123. The adjustment component 130 and the bracket component 120 are used in combination to facilitate the adjustment of the rotation angle of the photovoltaic panel 140, so that the photovoltaic panel 140 is adjusted to different positions and postures according to the light angle, thereby improving the power generation efficiency of the photovoltaic panel 140.

[0037] It is understandable that the adjustment angle of the photovoltaic panel 140 is 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, thereby achieving higher light energy absorption and conversion efficiency.

[0038] refer to Figures 1 to 3 As shown, the support structure 100 has a first direction. Exemplarily, the first direction is taken as the length direction of the support structure 100. It can be understood that the above definition is only for the purpose of facilitating the understanding of the relative position relationship of each part in the support structure 100, and should not be understood as a limitation to the present application.

[0039] In one embodiment, optionally, Figure 5As shown, the first movable member 123 is provided with a through slot 1231, and the cross beam 122 is passed through the through slot 1231 and is engaged with the slot wall of the through slot 1231. It can be understood that the first movable member 123 can be a universal joint member of a cylindrical structure, so that the cross beam 122 passes through the through slot 1231 of the universal joint member so that the cross beam 122 can be driven to rotate during the rotation of the first movable member 123, and the side of the universal joint member away from the photovoltaic panel 140 is fixedly connected to the column 121, that is, the cross beam 122 is rotatably connected to the column 121 through the universal joint member. In other words, when the adjustment component 130 drives the cross beam 122 to perform relative movement, the cross beam 122 can drive the photovoltaic panel 140 to rotate through the universal joint member.

[0040] It should be noted that the universal joint, also known as the universal joint bearing, is a mechanical component that is mainly used to achieve power transmission between different axes, especially suitable 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.

[0041] Furthermore, the through groove 1231 is a square structure, the cross section of the beam 122 is a square structure, the beam 122 is compatible with the size specifications of the through groove 1231, the beam 122 and the first movable part 123 rotate coaxially, so that the beam 122 drives the first movable part 123 to rotate during the rotation process, and the first movable part 123 drives the photovoltaic panel 140 to rotate, thereby realizing the adjustment of the angle and position posture of the photovoltaic panel 140 according to the light angle, thereby improving the light energy absorption and conversion efficiency.

[0042] In one embodiment, optionally, reference Figure 1 and Figure 2 As shown, the number of the columns 121 and the first movable parts 123 are both multiple, and the multiple columns 121 are arranged in parallel with each other at intervals, and one column 121 corresponds to one first movable part 123. During the relative rotation of the first movable part 123, the column 121 will not move, and the multiple first movable parts 123 can rotate at the same time, which can drive the photovoltaic panel 140 to rotate.

[0043] In one embodiment, optionally, in combination Figure 4 and Figure 6 As shown, the support structure 100 also includes a mounting bracket 141, and the mounting bracket 141 is arranged between the cross beam 122 and the photovoltaic panel 140. The mounting bracket 141 is used to fix and support the photovoltaic panel 140. Accordingly, the first movable part 123 drives the mounting bracket 141 to rotate relative to each other, and the mounting bracket 141 drives the photovoltaic panel 140 to move relative to each other, so as to achieve the purpose of adjusting the angle and position posture of the photovoltaic panel 140.

[0044] In summary, the support structure 100 for the offshore photovoltaic system can float on the sea through the floating body 110, the driving member 131 can drive the telescopic rod 133 to extend and retract relative to the fixed rod 132, and when the telescopic rod 133 moves, the adjusting member 134 drives the cross beam 122 to rotate, and the cross beam 122 drives the photovoltaic panel 140 to change its position. The cross beam 122 is movable and adjusted relative to the column 121 through the first movable member 123. The adjustment component 130 and the support component 120 are used in combination to facilitate the adjustment of the rotation angle of the photovoltaic panel 140, so that the photovoltaic panel 140 is adjusted to different positions and postures according to the light angle, thereby improving the power generation efficiency of the photovoltaic panel 140.

[0045] Example 2

[0046] refer to Figures 1 to 3 As shown, an embodiment of the present application provides another support structure 100 for an offshore photovoltaic system. The support structure 100 includes a floating body 110 , a support assembly 120 and an adjustment assembly 130 .

[0047] Specifically, combined Figure 3 and Figure 4 As shown, the support assembly 120 includes a crossbeam 122, a column 121 and a first movable member 123, one end of the column 121 is arranged on the float 110, and the end of the column 121 away from the float 110 is movably connected to the crossbeam 122 through the first movable member 123, and the side of the connecting member away from the column 121 is connected to the photovoltaic panel 140.

[0048] Specifically, the adjustment assembly 130 includes a driving member 131, an adjustment member 134, a fixing rod 132 and a telescopic rod 133. The adjustment member 134 is connected to the cross beam 122, the fixing rod 132 is telescopically connected to the telescopic rod 133, one end of the fixing rod 132 away from the telescopic rod 133 is hinged to the column 121, and one end of the telescopic rod 133 away from the fixing rod 132 is hinged to one end of the adjustment member 134 away from the cross beam 122. Accordingly, the support structure 100 can float on the sea through the floating body 110. The driving member 131 can drive the telescopic rod 133 to extend and retract relative to the fixed rod 132. When the telescopic rod 133 moves, the adjusting member 134 drives the cross beam 122 to rotate, and the cross beam 122 drives the photovoltaic panel 140 to change its position. The cross beam 122 is movable and adjusted relative to the column 121 through the first movable member 123. The adjustment component 130 and the bracket component 120 are used in combination to facilitate the adjustment of the rotation angle of the photovoltaic panel 140, so that the photovoltaic panel 140 is adjusted to different positions and postures according to the light angle, thereby improving the power generation efficiency of the photovoltaic panel 140.

[0049] It should be noted that in order to adapt to the special requirements of the marine environment, the float 110 has 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.

[0050] refer to Figures 1 to 3 As shown, the support structure 100 has a first direction. For example, the first direction is the length direction of the support structure 100. For example, the cross beam 122 and the floating body 110 are both arranged along the first direction.

[0051] In one embodiment, optionally, Figure 5 As shown, the first movable member 123 is provided with a through slot 1231, and the cross beam 122 is passed through the through slot 1231 and is engaged with the slot wall of the through slot 1231. It can be understood that the first movable member 123 can be a universal joint member, so that the cross beam 122 passes through the through slot 1231 of the universal joint member so that the cross beam 122 can be driven to rotate during the rotation of the first movable member 123, and the side of the universal joint member away from the photovoltaic panel 140 is fixedly connected to the column 121, and the universal joint member does not affect the column 121 during the rotation process, that is, the cross beam 122 is rotatably connected to the column 121 through the universal joint member. In other words, when the adjustment component 130 drives the cross beam 122 to perform relative movement, the cross beam 122 can drive the photovoltaic panel 140 to rotate through the universal joint member.

[0052] Furthermore, the through groove 1231 is a square structure, and the cross-section of the beam 122 along the first direction is a square structure, that is, the beam 122 is arranged along the first direction, and the size of the beam 122 is adapted to the through groove 1231. The beam 122 rotates coaxially with the first movable part 123, so that the beam 122 drives the first movable part 123 to rotate during the rotation process, and the first movable part 123 drives the photovoltaic panel 140 to rotate, thereby realizing the adjustment of the angle and position posture of the photovoltaic panel 140 according to the light angle, thereby improving the light energy absorption and conversion efficiency.

[0053] In one embodiment, optionally, in combination Figure 2 and Figure 6As shown, the end of the adjusting member 134 close to the telescopic rod 133 is provided with a second movable member 135, the second movable member 135 is hinged to the adjusting member 134, the end of the second movable member 135 away from the adjusting member 134 is movably connected to the telescopic rod 133, and the second movable member 135 is located between the adjusting member 134 and the telescopic rod 133. Accordingly, during the relative movement of the fixed rod 132 and the telescopic rod 133, the telescopic rod 133 drives the adjusting member 134 to move relative to each other through the second movable member 135, thereby driving the cross beam 122 to rotate, so that the cross beam 122 drives the first movable member 123 to rotate. Demonstratively, the second movable member 135 is rotatably connected to the end of the adjusting member 134 away from the cross beam 122.

[0054] In this embodiment, optionally, Figure 6 As shown, the rotation direction of the first movable member 123 is perpendicular to the first direction, and the relative movement direction of the second movable member 135 is perpendicular to the first direction, that is, the rotation direction of the first movable member 123 and the relative movement direction of the second movable member 135 are the same direction. It can be understood that the relative movement direction of the adjusting member 134 is the same direction as the rotation direction of the first movable member 123.

[0055] In one embodiment, optionally, reference Figure 1 and Figure 2 As shown, the number of the columns 121 and the first movable member 123 is multiple, and the multiple columns 121 are arranged in parallel at intervals, and one column 121 corresponds to one first movable member 123. During the relative rotation of the first movable member 123, the column 121 does not move, and the multiple first movable members 123 can rotate at the same time, which can drive the photovoltaic panel 140 to rotate. Furthermore, the multiple columns 121 are respectively perpendicular to the beam 122, and the beam 122 is supported by the multiple columns 121 and the adjustment function is achieved through the joint action to improve the stability of the support structure 100.

[0056] Optionally, refer to Figure 3 and Figure 4 As shown, the fixing rod 132 is arranged at an angle to the column 121, so that the fixing rod 132 has better supporting stability, and the connection between the fixing rod 132 and the column 121 is hinged, that is, there is a certain amount of movable margin between the fixing rod 132 and the column 121, so that when the angle of the photovoltaic panel 140 is adjusted, the angle between the fixing rod 132 and the column 121 changes.

[0057] Alternatively, if Figure 4As shown, the driving member 131 is disposed on a side of the fixing rod 132 away from the column 121 , and the driving member 131 is used to drive the telescopic rod 133 to be telescoped relative to the fixing rod 132 . Exemplarily, the driving member 131 may be a driving cylinder.

[0058] In one embodiment, optionally, in combination Figure 4 and Figure 6 As shown, the support structure 100 further includes a mounting bracket 141, which is disposed between the crossbeam 122 and the photovoltaic panel 140. The mounting bracket 141 is used to fix and support the photovoltaic panel 140. Accordingly, the first movable member 123 drives the mounting bracket 141 to rotate relatively, and the mounting bracket 141 drives the photovoltaic panel 140 to move relatively, so as to adjust the angle and position of the photovoltaic panel 140. Furthermore, the material of the mounting bracket 141 can be selected from metal or non-metal. For example, the material of the mounting bracket 141 is a metal alloy, such as an aluminum alloy.

[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.
